AfterWindows & Doors in Concord, CA
Window installation in Concord means replacing 1960s and 1970s aluminum single-pane units that were never designed for Diablo Valley heat. Most of the housing stock here still carries original frames, and the 100°F afternoons followed by 60°F Delta breeze evenings put a thermal beating on glass and frames that coastal cities never experience. Call (509) 265-6387 for a written price before any work starts.
Why Concord Homes Are Different
Concord sits in California’s Building Energy Climate Zone 12, where summer highs routinely reach 100-105°F. That’s often 35°F hotter than San Francisco on the same afternoon, and the housing stock reflects an era when nobody planned for it. The single-story ranches and two-story tract homes that spread across Concord through the 1950s, 60s, and 70s went up with aluminum-frame single-pane windows, sliding glass patio doors with worn tracks, and hollow-core exterior doors. All of it is now past useful service life.
What makes Zone 12 compliance genuinely different is the low-SHGC requirement. SHGC stands for solar heat gain coefficient, and it measures how much solar radiation passes through the glass. Concord’s Title 24 standard demands lower SHGC values than coastal Bay Area cities just 20 miles west. A window that passes code in Oakland may not pass in Concord. That’s not a paperwork nuance. It changes which glass gets specified on every opening.
The thermal cycling also does measurable damage. Daily swings of 35-45°F cause seal failure on insulated glass units sooner than in milder climates, and door frames warp faster. Technicians working Concord’s east-side 1970s tracts repeatedly find aluminum sliding window tracks warped out of square from decades of expansion and contraction. Off-the-shelf frame sizing from a coastal supplier often needs field adjustment just to get the sash to operate correctly after installation.
Our Main Concord Services
Two services account for most of the calls we take from Concord homeowners, and both have their own dedicated pages with full pricing detail.
Door Installation in Concord
Concord’s original hollow-core exterior doors were never much of a thermal or security barrier, and after 50 to 60 years of Diablo Valley temperature swings many have warped enough to show daylight around the frame. We replace entry doors, patio doors, and garage doors with properly sized units matched to the opening’s actual measurements, not the nominal size on the original blueprint. See the full breakdown on the Door Installation in Concord page.
Window Replacement in Concord
Most Concord homes are still running original aluminum single-panes, and the heat load is the reason they fail. Single-pane aluminum frames conduct thermal energy straight into the house, and the afternoon heat bleeds through the wall of glass facing west. The Window Replacement in Concord page covers the full replacement scope, including what happens when the existing frame is no longer square enough to accept a stock sash.

BeforeAfterWindow Installation in Concord
Window installation in Concord is a glass-specification exercise as much as a carpentry one. The housing stock runs from 1950s ranches to 1970s two-story tracts, and nearly all of it still carries original aluminum single-pane windows that predate Zone 12’s low-SHGC compliance standard. A replacement window here has to control solar heat gain during 100°F afternoons and still hold its seal through 45°F overnight swings. We measure every opening, write the scope, and hand you the price before any tool is lifted. See Window Installation for the full service detail.
Single & Double Hung Windows
Signs you need it
You can feel heat radiating through the glass on a summer afternoon, or the sash has become difficult to raise and no longer stays open without support.
What it costs in Concord
Replacing an original aluminum single-hung with a double-hung low-E unit in Concord typically runs $380-$740 per window, depending on size and frame condition.
How we do it
We remove the old sash and frame, check the rough opening for square, install the new unit with fresh flashing, and verify operation and seal before we leave the property.
Horizontal Roller Windows
Signs you need it
The sash scrapes or binds when sliding, or the aluminum track has warped enough that the window no longer closes flush against the frame.
What it costs in Concord
Expect to pay $420-$810 per horizontal roller window in Concord, with the upper end covering field adjustment for warped 1970s aluminum tracks.
How we do it
We pull the existing sash, square the opening where thermal cycling has moved it, set the new roller track, and install a unit sized to the actual frame dimensions.
3-Panel Sliding (3-Lite Roller) Windows
Signs you need it
The center panel no longer aligns with the outer panels, or multiple lites have failed seals showing condensation between the glass.
What it costs in Concord
This is a $1,100-$2,400 opening in Concord, driven by the width of the opening and the number of panels being replaced together.
How we do it
We replace the entire 3-panel assembly as a unit, shimming and leveling the new frame to account for any settling in the original rough opening.
Casement Windows
Signs you need it
The crank mechanism fails to close the sash tightly, or the seal between glass and frame has degraded enough that you can feel a draft.
What it costs in Concord
Casement window replacement in Concord typically lands between $620 and $1,150 per unit, including hardware replacement.
How we do it
We remove the old casement assembly, confirm the hinge-side framing is still sound, install the new energized unit, and test the full crank travel.
Awning & Hopper Windows
Signs you need it
Bathroom or basement ventilation windows have corroded hinges or no longer seal tightly enough to keep conditioned air inside.
What it costs in Concord
Budget $330-$620 per awning or hopper window in Concord, varying by glass type and whether the existing frame can be reused.
How we do it
We measure the existing rough opening, supply a correctly sized awning or hopper unit, and install it with new weatherstripping and hardware.
What Window Installation Costs in Concord
| Item | Typical range in Concord |
|---|---|
| Single or double hung window | $380 - $740 per window |
| Horizontal roller window | $420 - $810 per window |
| 3-panel sliding window | $1,100 - $2,400 per opening |
Do I need low-SHGC glass for window installation in Concord?
Yes. Climate Zone 12 requires lower SHGC values than the coastal Bay Area, so a window that passes code elsewhere may not pass in Concord. We specify glass against the Title 24 compliance standard for your address. Call (509) 265-6387 for an exact quote.
Will my window price change once work starts?
No. The measured survey is the same document as the written quote. If the opening needs field adjustment for warped tracks, that work is already accounted for in the original price. Call (509) 265-6387 to schedule a free estimate.
Impact Windows & Doors in Concord
Impact windows and doors in Concord are not just about storm protection. The laminated glass that makes a unit impact-rated also significantly reduces solar heat gain, and on a 105°F Diablo Valley afternoon that’s the feature homeowners actually feel. Original aluminum frames on 1960s and 70s tract homes lack the structural strength to hold an impact-rated laminate long-term, so most Concord jobs start with a full frame replacement. We specify from PGT, CGI, and CWS lines based on what the opening requires, not what’s in stock. See Impact Windows & Doors for full product details.
Impact-Resistant Windows
Signs you need it
You’re replacing original single-pane units and want a glass package that stands up to both flying debris and Concord’s summer heat gain.
What it costs in Concord
Impact-resistant windows in Concord run $980-$1,850 per opening, with the lamination adding roughly 45% over a standard low-E unit.
How we do it
We measure the opening, specify the correct laminate layering for the exposure, and install the unit into a structurally sound new frame, not a retrofit into old aluminum.
Hurricane Impact Windows
Signs you need it
Your home faces a wide western or southern exposure where afternoon heat and wind-driven debris are both year-round concerns.
What it costs in Concord
Hurricane-rated units with full Miami-Dade compliance typically run $1,150-$2,100 per window in Concord depending on size and frame material.
How we do it
We order units matched to the opening’s exact dimensions, pull the old frame, set the new one plumb, and install the impact glass with the proper glazing seal.
Single Hung Impact Windows
Signs you need it
Bedroom and living-room windows on the front elevation face the afternoon sun and need impact protection with a traditional single-hung look.
What it costs in Concord
Single hung impact units run $900-$1,650 per window in Concord, depending on the laminate thickness and frame finish.
How we do it
We replace the full frame with a modern single-hung impact assembly, setting it square to the rough opening and sealing around all four sides.
Double Hung Impact Windows
Signs you need it
You want the ventilation of a double hung with the protection of laminated glass, and the existing wood or aluminum frame is too far gone to reuse.
What it costs in Concord
Double hung impact windows cost $1,050-$1,900 per opening in Concord, with the upper end covering larger bedroom units.
How we do it
We remove the old sash and frame, enlarge the rough opening only if needed for the thicker impact unit, and install with new jamb liners.
Horizontal Roller & Sliding Impact Windows
Signs you need it
Your ranch home’s wide living-room openings use sliding units, and the aluminum tracks are no longer square enough to keep the sash sealed.
What it costs in Concord
Expect $1,200-$2,400 per sliding impact unit in Concord, with track field adjustment included in the written price.
How we do it
We field-size the replacement to the actual opening, shim the track true, and set the impact slider into a fully sealed new frame.
What Impact Windows & Doors Costs in Concord
| Item | Typical range in Concord |
|---|---|
| Impact-resistant windows | $980 - $1,850 per opening |
| Hurricane impact windows | $1,150 - $2,100 per window |
| Horizontal roller / sliding impact | $1,200 - $2,400 per unit |
Are impact windows worth it in Concord if I’m not near the coast?
Yes, primarily for the laminated glass. Concord’s summer heat load is severe, and the laminate layer cuts solar heat gain meaningfully while adding break-in resistance. Call (509) 265-6387 for a written quote with exact glass specs.
Do impact windows meet Concord’s Title 24 energy standard?
They can, if the glass is specified with a low-SHGC coating as well as the impact laminate. We order every Concord unit with both so you don’t have to choose between code compliance and protection. Call (509) 265-6387 to confirm.
Energy-Efficient Windows in Concord
Energy-efficient windows in Concord are a Title 24 requirement, not an upsell. Climate Zone 12’s low-SHGC mandate exists because the Diablo Valley traps heat, and a west-facing wall of old single-pane glass can make an air conditioner run nearly constantly in July. The 1960s and 70s tract stock was built before low-E coatings existed, so nearly every original window in Concord is an energy liability by today’s measured standard. We specify glass by U-factor and SHGC for each elevation, because a south-facing window in Concord needs a different package than a north-facing one. See Energy-Efficient Windows for the full glass comparison.
Low-E & Argon Gas Glass
Signs you need it
Your summer cooling bill is consistently high, or you can feel a difference in surface temperature between the glass and the surrounding wall.
What it costs in Concord
Low-E with argon gas fill adds $70-$140 per window over standard double-pane glass in Concord, depending on the coating type.
How we do it
We replace the existing unit with a dual-pane assembly carrying a low-E coating matched to the elevation, then fill the cavity with argon gas.
ENERGY STAR Replacement Windows
Signs you need it
You’re replacing original aluminum single-panes and want a certified package that meets both Zone 12 Title 24 and ENERGY STAR criteria.
What it costs in Concord
ENERGY STAR-rated replacements in Concord typically run $410-$760 per window, excluding any frame replacement work.
How we do it
We install the rated unit into a properly flashed, squared opening, and leave you with the glass performance documentation for your records.
Insulated Laminated Glass
Signs you need it
You want both noise reduction from nearby traffic and the thermal performance of dual-pane construction in one glass package.
What it costs in Concord
Insulated laminated glass runs $530-$960 per window in Concord, with the laminate layer carrying both acoustic and safety benefits.
How we do it
We order units with a laminate interlayer bonded inside the dual-pane assembly, then install into a frame sized for the thicker profile.
UV-Blocking & Fade Protection
Signs you need it
Furniture, flooring, or artwork near south- and west-facing windows is fading noticeably within a few years of installation.
What it costs in Concord
UV-blocking glass packages in Concord add $60-$120 per window, depending on whether the coating is applied to one surface or both.
How we do it
We specify a UV-filtering coating on the interior-facing glass surface, which blocks most fading radiation without darkening the room.
Solar & Tinted Glass Options
Signs you need it
Your west-facing rooms overheat badly in the afternoon, and you want solar control without relying solely on window coverings.
What it costs in Concord
Solar-control and tinted glass runs $480-$890 per window in Concord, with the price varying by tint density and coating performance.
How we do it
We match the tint or solar coating to the orientation and your target SHGC, then install the unit with the coating on the correct surface for the climate.
What Energy-Efficient Windows Costs in Concord
| Item | Typical range in Concord |
|---|---|
| Low-E with argon gas | $70 - $140 per window add-on |
| ENERGY STAR replacement | $410 - $760 per window |
| Insulated laminated glass | $530 - $960 per window |
What SHGC rating do I need for Concord?
Zone 12 requires a lower SHGC than the coastal East Bay, typically 0.25 or below on south- and west-facing glass. We run the exact number for your address before ordering. Call (509) 265-6387 for a written estimate.
Will energy-efficient windows actually lower my Concord cooling bill?
On original single-pane aluminum openings, yes, typically by 15-25% depending on exposure and the number of openings replaced. The biggest gains come on west-facing glass. Call (509) 265-6387 for exact specs.
Sliding & Patio Doors in Concord
Sliding and patio doors in Concord take more abuse than almost any other opening. The original aluminum sliders on 1960s and 70s tract homes wore through their tracks decades ago, and the daily thermal swing keeps working on whatever’s left. When a slider binds in summer and rattles in winter, the issue is usually a frame that’s no longer square from years of expansion and contraction. We replace the entire assembly, track included, rather than putting a new panel into a warped frame. See Sliding & Patio Doors for full scope details.
Patio Doors
Signs you need it
The door drags across a worn track, or you can see daylight through the weatherstripping at the top or bottom corners.
What it costs in Concord
Patio door replacement in Concord runs $1,850-$3,400 per opening, with the upper end covering larger ranch-home sliders.
How we do it
We pull the old panel and track, square the rough opening, and install a new door assembly sized to the actual dimensions we measured.
Impact Sliding Glass Doors
Signs you need it
You’re replacing a wide rear slider that faces the afternoon sun, and you want both impact protection and solar control in the same panel.
What it costs in Concord
Impact sliding glass doors in Concord typically run $2,400-$4,800 per opening, depending on width and laminate specification.
How we do it
We field-measure the opening, order a laminated impact panel to spec, and install it into a new track system with rollers rated for the heavier glass.
Sliding Glass Door Replacement
Signs you need it
The track is physically bent or the rollers have worn through the aluminum, and the door no longer locks properly against the jamb.
What it costs in Concord
Replacing a standard sliding glass door in Concord costs $1,750-$3,200, including new track and hardware.
How we do it
We replace the full door assembly, level the track across the opening, and verify the lock and latch alignment before finishing.
Impact French Patio Doors
Signs you need it
You want the look of a French door with the glass performance and impact resistance to handle Concord’s western exposure.
What it costs in Concord
Impact French patio doors in Concord run $2,600-$5,200 per opening, with the wide range driven by panel count and glass package.
How we do it
We install the French door assembly with laminated glass in each leaf, set both active and passive panels plumb, and seal the full perimeter.
Screen Door Installation
Signs you need it
Your existing screen door has torn mesh or a bent frame, or the original screen was removed and never replaced.
What it costs in Concord
Screen door installation in Concord runs $180-$420 per door, depending on frame material and whether it’s a sliding or hinged unit.
How we do it
We measure the opening, supply a correctly sized screen door matched to the existing track or hinge hardware, and install it with fresh seals.
What Sliding & Patio Doors Costs in Concord
| Item | Typical range in Concord |
|---|---|
| Standard patio door | $1,850 - $3,400 per opening |
| Impact sliding glass door | $2,400 - $4,800 per opening |
| Screen door installation | $180 - $420 per door |
Can you fix a sliding door that’s off its track in Concord?
Usually yes, if the track itself isn’t bent and the frame is still square. We inspect the rollers and the alignment first, then tell you whether a repair or replacement makes sense. Call (509) 265-6387 for a written diagnosis.
How long does a sliding door replacement take in Concord?
Most Concord patio door replacements are completed in one day, including removal, track leveling, new door installation, and sealing. The written scope we give you before work starts confirms the timeline. Call (509) 265-6387 to schedule.
Impact Garage Doors in Concord
Impact garage doors in Concord solve a problem most homeowners don’t think about until the garage faces a summer afternoon with a west exposure. The original hollow-core metal doors on 1960s and 70s tract homes conduct heat straight into the garage, which then bleeds into the house through the shared wall. An impact-rated insulated door handles both the thermal load and any wind-driven debris, and it’s one of the more cost-effective energy upgrades we install in Concord. See Impact Garage Doors for the full product lineup.
Hurricane-Rated Garage Doors
Signs you need it
Your garage door faces a wide open exposure, or you’re replacing a lightweight original door that flexes under moderate wind pressure.
What it costs in Concord
Hurricane-rated garage doors in Concord run $2,850-$5,800 per door, depending on width, insulation level, and rail reinforcement.
How we do it
We remove the old panel assembly, reinforce the rail system to support the heavier door, and install the new hurricane-rated unit with balanced springs.
Energy-Efficient Garage Doors
Signs you need it
Your garage is noticeably hotter than the rest of the house on summer afternoons, and the existing door is uninsulated sheet metal.
What it costs in Concord
Energy-efficient garage doors in Concord cost $2,100-$4,600, with the insulation value and panel material driving most of the range.
How we do it
We replace the existing door with an insulated panel assembly, install new weatherstripping around the full perimeter, and adjust the opener for the new weight.
Garage Door Replacement
Signs you need it
The panels are dented, the door no longer balances properly, or the thermal cycling has warped the original frame enough that it binds.
What it costs in Concord
Standard garage door replacement in Concord runs $1,900-$3,800, including track and hardware, with impact-rated models above that range.
How we do it
We remove the old door and rails, set new tracks plumb and level, install the replacement door, and balance it with new springs.
Wind-Load Code Compliance
Signs you need it
A recent inspection flagged the existing garage door as non-compliant with current wind-load standards, or you’re planning a remodel that triggers a review.
What it costs in Concord
Bringing a garage door into wind-load compliance in Concord typically adds $800-$1,500 over a standard replacement, depending on the opening.
How we do it
We review the compliance requirement for your specific address, specify a door assembly that meets it, and document the installation for the inspector.
What Impact Garage Doors Costs in Concord
| Item | Typical range in Concord |
|---|---|
| Hurricane-rated garage door | $2,850 - $5,800 per door |
| Energy-efficient garage door | $2,100 - $4,600 per door |
| Standard garage door replacement | $1,900 - $3,800 per door |
Do I need a permit to replace my garage door in Concord?
Most like-for-like replacements don’t require a permit, but changing the opening size or structural headers does. We handle the permit paperwork when it’s needed and document everything for inspection. Call (509) 265-6387 to check your specific opening.
Can an impact garage door really lower my Concord cooling bill?
Yes, when the garage shares a wall with conditioned space. Insulated impact doors can cut heat transfer through that wall noticeably during summer months. Call (509) 265-6387 for exact numbers on your opening.
Custom & Geometric Windows in Concord
Custom and geometric windows in Concord often come up during remodels of 1960s and 70s tract homes, where the original layout didn’t include anything beyond standard rectangles. Adding a radius or trapezoid unit changes both the house and the Title 24 calculation, because every new opening in Zone 12 still has to meet the low-SHGC standard. We fabricate to the exact sightline the architect or homeowner specifies, then verify the glass performance before installation. See Custom & Geometric Windows for the full fabrication process.
Custom Impact Windows
Signs you need it
You’re adding or replacing a large, unusually shaped window and want impact protection without giving up the design.
What it costs in Concord
Custom impact windows in Concord run $1,300-$2,800 per opening, with the non-standard fabrication driving the premium over stock sizes.
How we do it
We measure the rough opening, create a fabrication drawing, order the laminated unit cut to spec, and install it into a properly framed opening.
Geometric & Shaped Windows
Signs you need it
You want a trapezoid, pentagon, or other non-rectangular window to fit a specific architectural feature or roofline.
What it costs in Concord
Geometric window fabrication in Concord typically runs $900-$2,200 per unit, depending on the number of sides and glass type.
How we do it
We take exact field measurements, produce a template, and order the unit with the right low-SHGC glass for the opening’s orientation.
Arched & Curved Windows
Signs you need it
You’re replacing a failed arch-top unit or adding a radius window to a remodel, and the existing rough opening needs to be matched exactly.
What it costs in Concord
Arched and curved windows in Concord cost $1,100-$2,500 per unit, with the radius fabrication adding roughly 30% over a rectangular equivalent.
How we do it
We template the curve precisely, send the drawing for fabrication, and install the finished unit into an opening cut to the same dimensions.
Oversized Openings
Signs you need it
You’re opening up a wall for a large picture window or a floor-to-ceiling glass panel, and the structural header needs to be resized.
What it costs in Concord
Oversized window openings in Concord run $2,200-$4,800, including header work, framing, and the custom glass unit.
How we do it
We coordinate the structural design, pull the permit when required, resize the opening, and install the oversized unit with proper flashing.
What Custom & Geometric Windows Costs in Concord
| Item | Typical range in Concord |
|---|---|
| Custom impact window | $1,300 - $2,800 per opening |
| Geometric or shaped window | $900 - $2,200 per unit |
| Oversized opening | $2,200 - $4,800 per opening |
Can you match an existing arch-top window in a 1970s Concord tract home?
Yes. We template the existing curve rather than working from plan dimensions, because those original openings are rarely perfectly true after 50 years. Call (509) 265-6387 for a written quote on the match.
Do custom windows in Concord still need to meet Title 24?
Yes. Every new opening, regardless of shape, has to meet Zone 12’s low-SHGC standard. We specify the glass for compliance and hand you the documentation with the installed unit. Call (509) 265-6387 to discuss your opening.
