AfterWindows & Doors in Brentwood, CA
Window installation in Brentwood, CA runs $450-$1,100 per opening for standard retrofit work, with whole-home replacement on a 1997-2007 production build typically landing between $9,000 and $24,000. Most Brentwood homes were built during one of California’s fastest housing booms, and the original builder-grade dual-pane units are now failing seal after seal across entire subdivisions at once. Call (509) 265-6387 if you’re seeing fogged glass or feeling heat bleed through frames; the first step is a measured survey you keep.
Why Brentwood Homes Are Different
Brentwood’s housing stock is unusual because it arrived almost all at once. Between 1997 and 2007, production builders like KB Home, Shea, Pulte, and Centex completed large stucco-clad two-story tracts across the city, and nearly every one used the same tier of builder-standard vinyl or aluminum-framed dual-pane windows specified to the California Title 24 minimums of that era. Those units are now 20 to 25 years old, which is exactly when the spacer seals fail, the argon gas leaks out, and fogged glass starts appearing house after house on the same street.
The climate pushes that timeline harder here than in most of the Bay Area. Brentwood sits inland past the Altamont Pass with minimal marine influence, so summer afternoons regularly hit 100-110°F, far hotter than Livermore or Oakland. West- and south-facing windows absorb that heat all day, then the Delta breeze cools things off after sunset. That daily thermal cycling stresses the seals on aging dual-pane units faster than the milder temperature swings closer to the coast, which is why we see more premature seal failure in Brentwood than in any neighboring city.
There’s also a practical advantage to how Brentwood was built. In age-restricted communities like Summerset and Trilogy at Brentwood, every home came from the same builder package in the same two-to-three-year window. Once we identify the OEM window brand and series from one unit, we can pre-order matching replacement sashes for an entire cul-de-sac, which shortens lead time and reduces the number of trips we need to make.
Our Main Brentwood Services
Two jobs account for most of the calls we get in Brentwood: replacing failed windows and replacing worn entry doors. Both are covered in detail on their own pages, linked below.
Door Installation in Brentwood
Brentwood’s production homes shipped with hollow-core front doors that haven’t aged well in the Delta heat. Warping, gaps at the threshold, and swollen frames are common, and the stucco returns on many 2000s-era entries mean the rough opening has to be handled carefully so the weatherproofing ties back correctly. We measure the existing opening, spec the replacement door from Therma-Tru or ViewLux, and leave you the measured survey before any work begins. Full details are on the Door Installation in Brentwood page.
Window Replacement in Brentwood
If your windows fog between the panes or the frames are warm to the touch on a summer afternoon, they’ve reached the end of their service life. In Brentwood, that usually means replacing builder-grade dual-pane units from the 1997-2007 boom era with modern low-E glass that actually blocks the inland sun. The job in most tracts is a retrofit with the existing stucco left intact. The Window Replacement in Brentwood page covers costs, timelines, and what the written scope includes.

BeforeAfterWindow Installation in Brentwood
Window installation in Brentwood is dominated by one job: replacing the original builder-grade dual-pane units that went into every KB Home, Shea, Pulte, and Centex subdivision between 1997 and 2007. Those windows are now failing in clusters, and the 100-110°F summer days mean a failed seal isn’t cosmetic; it’s direct heat transfer into rooms that are already expensive to cool. Our Window Installation work always starts with a measured survey that becomes the written quote, so the price is fixed before a tool is lifted.
Single & Double Hung Windows
Signs you need it
Sashes that won’t stay up, fogged glass between the panes, or rattling in the frame are the telltale signs on Brentwood’s older two-story floor plans, where the upstairs hung windows catch the most afternoon sun and fail first.
What it costs in Brentwood
Expect to pay $320-$850 per single hung and $410-$1,150 per double hung installed in Brentwood, depending on the glazing package and frame material.
How we do it
We remove the existing sash, inspect the frame for rot or racking, install the new hung unit with insulated glass specified to the exposure, and close the interior stops before caulking the exterior line and leaving the photo record.
3-Panel Sliding (3-Lite Roller) Windows
Signs you need it
A center panel that grinds or jumps the track, a frame that’s visibly out of square on stucco walls, or condensation between the panes means the original 2000s-era slider has failed.
What it costs in Brentwood
A 3-panel sliding window replacement in Brentwood runs $1,400-$3,200 per opening, with the final number set by the width and the glazing you choose.
How we do it
We verify the rough opening and the sightline before ordering, then set the new 3-lite frame, level the rollers, and land the panels with the locking rail aligned so all three close as a single assembly.
What Window Installation Costs in Brentwood
| Item | Typical range in Brentwood |
|---|---|
| Single hung window, standard vinyl, low-E | $320-$850 per window |
| Double hung window, standard vinyl, low-E | $410-$1,150 per window |
| 3-panel sliding window | $1,400-$3,200 per opening |
How long does window installation take in Brentwood?
Most single-opening retrofit installs are done in a day, and a whole-home replacement of 15-25 windows typically takes two to three working days. The written scope lists the sequence and schedule before we start.
Will the price change once the stucco comes off?
The measured survey covers the frame condition behind the old window before it’s removed, so if hidden rot changes the scope, that change is written and approved before we cut. Call (509) 265-6387 for a fixed-price estimate.
Impact Windows & Doors in Brentwood
Impact windows in Brentwood aren’t required by code the way they are in coastal Florida, but the city’s climate still makes them worth pricing: 100°F-plus summer afternoons and the high winds that come off the Delta put real stress on large glass openings. Builders in the 1997-2007 boom installed standard dual-pane units, so most Brentwood homes have zero impact-rated glazing. Our Impact Windows & Doors work upgrades those openings with laminated glass that holds together under impact and cuts solar heat gain at the same time.
Impact-Resistant Windows
Signs you need it
West-facing openings that heat up a room so fast the AC runs nonstop from June through September, or single-pane glass in a 1990s addition, are the places to start.
What it costs in Brentwood
Impact-resistant windows in Brentwood run $850-$2,600 per opening depending on the size, the frame, and the product line, with PGT and CGI units at the higher end of that range.
How we do it
We measure the opening and the wind exposure, spec laminated impact glass to the actual load the wall will see, order the unit with the correct SHGC, and install with structural brackets and a full perimeter seal.
Double Hung Impact Windows
Signs you need it
Older double hungs on second-floor bedrooms that face south or west with no shading and single-strength glass are the strongest candidates for an impact-rated upgrade in Brentwood.
What it costs in Brentwood
Double hung impact windows in Brentwood start around $1,100 and reach $2,800 per window for larger sizes in PGT or CGI frames.
How we do it
We pull the old sashes, verify the opening is square, attach the new impact-rated frame with through-frame anchors, set both sashes, and test the balance and the tilt latches before sealing.
What Impact Windows & Doors Costs in Brentwood
| Item | Typical range in Brentwood |
|---|---|
| Impact-resistant window, standard size | $850-$2,600 per window |
| Double hung impact window | $1,100-$2,800 per window |
| Impact sliding glass door | $5,500-$12,000 per door |
Do Brentwood homes need impact windows?
No code in Brentwood requires impact glazing the way Miami-Dade does, but the wind loads coming off the Delta and the inland heat are real. The payoff comes in lower cooling costs and glass that won’t shed into the room if a branch or debris hits it. Call (509) 265-6387 to price your openings.
What’s the difference between impact-rated and impact-resistant?
Impact-rated means the glass and frame were tested together to a specific standard, usually ASTM E1886 and E1996. Impact-resistant is a looser marketing term without a test certificate. We use only tested and labeled units from PGT and CGI.
Energy-Efficient Windows in Brentwood
Energy-efficient windows in Brentwood are a direct response to the city’s summer reality: daytime highs of 100-110°F with no marine layer to soften the heat. When the original builder-grade dual-pane windows from the boom era lose their seal or never had low-E coatings to begin with, the west and south exposures turn those rooms into ovens. Our Energy-Efficient Windows service specifies glazing by orientation, so the U-factor and SHGC on the west side of the house aren’t the same as on the shaded north side.
Low-E & Argon Gas Glass
Signs you need it
Rooms that run 10 or 15 degrees hotter than the rest of the house, glass that’s warm to the touch from inside, or cooling bills that spike every July and August all point to missing or failed low-E.
What it costs in Brentwood
Low-E with argon glass in Brentwood adds $350-$900 per window, with the price set by the glazing package and whether it’s a retrofit or a full tear-out.
How we do it
We read the compass orientation and the shade conditions, pick a low-E coating with the right solar heat gain coefficient for that wall, then order argon-filled insulated units sized to the actual opening.
ENERGY STAR Replacement Windows
Signs you need it
Any Brentwood home with the original 1997-2007 builder windows will save measurable cooling cost by moving to ENERGY STAR-rated units, especially on south and west walls.
What it costs in Brentwood
ENERGY STAR replacement windows in Brentwood run $450-$1,400 per window installed, depending on the frame material and the glazing level.
How we do it
We spec the window with the climate zone in mind, confirm the ENERGY STAR label and the NFRC numbers, install the unit with an air seal at the rough opening, and hand you the spec sheet with the final invoice.
What Energy-Efficient Windows Costs in Brentwood
| Item | Typical range in Brentwood |
|---|---|
| Low-E & argon gas glass upgrade | $350-$900 per window |
| ENERGY STAR replacement window, vinyl | $450-$1,400 per window |
| Full-home energy package, 15-20 windows | $8,000-$22,000 per home |
Which windows should I upgrade first in Brentwood?
Start with the west and south exposures; those are the walls that take the full inland heat from noon to sunset. A measured survey will show you which openings carry the most load, and you keep that document. Call (509) 265-6387 to schedule one.
How much will I actually save on cooling?
Savings depend on the orientation, the existing glass, and how much you run the AC, but replacing failed builder-grade units with low-E argon typically cuts the cooling load on those rooms by 20-35%. We can calculate the projected solar gain difference in writing.
Sliding & Patio Doors in Brentwood
The wide Delta temperature swings make the aluminum frames expand and contract daily, which is why we see so many rollers fail and so many locking rails sheared off in this particular housing stock. Our Sliding & Patio Doors replacements are measured to the actual slab, not the old door, so the new unit closes square and seals tight.
Sliding Glass Door Replacement
Signs you need it
A door that takes two hands to move, condensation permanently between the panes, or a locking rail that no longer meets the jamb means the original builder unit is done.
What it costs in Brentwood
A standard 6-foot sliding glass door replacement in Brentwood runs $1,700-$4,200, and larger or multi-track units run more.
How we do it
We remove the old panel and frame, check the slab for level, set the new frame plumb in the rough opening, seat the rollers, and lap the weatherstripping before re-trimming the interior.
Impact French Patio Doors
Signs you need it
French doors on west-facing patios heat up fast and often carry single-pane glass, a poor setup for Brentwood’s afternoon sun and the Delta wind gusts.
What it costs in Brentwood
Impact French patio doors in Brentwood run $4,500-$10,500 per opening, with the final number set by the width, the number of leaves, and the glass package.
How we do it
We measure the full rough opening, order the hinged impact unit with rated astragals, anchor the jamb, and adjust each panel so the leaves land on the center mullion and seal at the sill.
What Sliding & Patio Doors Costs in Brentwood
| Item | Typical range in Brentwood |
|---|---|
| Sliding glass door replacement, standard 6-foot | $1,700-$4,200 per door |
| Impact sliding glass door | $5,500-$12,000 per door |
| Impact French patio door | $4,500-$10,500 per opening |
How long does a patio door replacement take in Brentwood?
Most sliding door replacements are done in one day. French doors with stucco returns or framing repairs may run two days. The written schedule tells you the crew size and the day-by-day plan before work starts.
Can you match the stucco around the new door?
We preserve the existing stucco return wherever the rough opening is sound and only cut what’s required to set the new frame. If stucco repair is needed, it’s priced in the written scope, not added later. Call (509) 265-6387 for a fixed quote.
Impact Garage Doors in Brentwood
Impact garage doors in Brentwood are less about hurricanes and more about the test of inland heat, wind off the Delta, and the sheer size of the door opening on a three-car garage. Standard production-home garage doors from the boom era are thin steel or wood composite, and after two decades they flex, rack, and let hot air pour into the garage and the rooms above it. Our Impact Garage Doors service upgrades the opening to a wind-rated, insulated door that changes how the whole front of the house performs.
Hurricane-Rated Garage Doors
Signs you need it
A door that bows inward when you push on it, tracks that have pulled from the wall, or a homeowner’s association asking about wind-load compliance are all reasons to look at a rated door.
What it costs in Brentwood
Hurricane-rated garage doors in Brentwood run $2,400-$8,000 per door, with the final number set by the width, the track system, and the wind-load rating you choose.
How we do it
We measure the opening and the header, check the existing track for deflection, order a rated door with the correct design pressure for the exposure, and replace the brackets and hinges as needed.
Garage Door Replacement
Signs you need it
A door that won’t balance, panels that have begun to delaminate from heat cycling, or a track that’s out of alignment after years of Brentwood’s hot-cold swing means the whole assembly should go.
What it costs in Brentwood
A standard garage door replacement in Brentwood runs $1,600-$3,800 for a typical two-car door, with insulated and impact-rated options above that.
How we do it
We release the spring tension safely, remove the old panels and track, set the new track to plumb, install the new spring system, hang the fresh panels, and test the balance and the auto-reverse.
What Impact Garage Doors Costs in Brentwood
| Item | Typical range in Brentwood |
|---|---|
| Standard garage door replacement, two-car | $1,600-$3,800 per door |
| Hurricane-rated garage door | $2,400-$8,000 per door |
| Energy-efficient insulated garage door | $2,000-$6,500 per door |
Why would I need a hurricane-rated garage door in Brentwood?
Brentwood isn’t in a hurricane zone, but high Delta winds and the sheer size of a production-home garage opening make a rated door a structural improvement. It’s also the door most likely to fail if high wind pushes it past its design load. Call (509) 265-6387 to have the opening assessed.
Should garage door springs be repaired by a professional?
Yes. Garage door springs are under dangerous tension, and a failing spring can release that energy without warning. This is not a DIY repair. A trained technician has the tools and the calibrated winding bars to do the job without injury.
Custom & Geometric Windows in Brentwood
Custom and geometric windows in Brentwood usually mean one thing: the original production-home openings are odd shapes, and the builder-grade units inside them were always the weak link. Half-rounds, trapezoids, and oversized picture windows on the front elevation or the stairwell wall are common in the 1997-2007 tracts, and when their seals fail, they’re harder to replace than a standard rectangle. Our Custom & Geometric Windows service measures the exact radius, angle, and rough opening so the replacement fits the first time and keeps the stucco line intact.
Arched & Curved Windows
Signs you need it
Fogged arched glass on the front elevation, a curved frame that has pulled away from the stucco, or an eyebrow vent that’s impossible to clean on the second floor means the unit has failed.
What it costs in Brentwood
Arched and curved windows in Brentwood run $1,500-$3,800 per opening, with the higher end for custom radii and laminated glazing.
How we do it
We photograph and measure the exact arc, send the template to the manufacturer, order the bent or cast frame with the matching glazing, and install the curved unit into the original opening with the same sightline.
Oversized Openings
Signs you need it
A two-story picture window that’s now fogged or bowing, a patio-to-ceiling glass wall that flexes in the wind, or a stairwell opening that’s impossible to reach with standard stock means a custom order.
What it costs in Brentwood
Oversized custom openings in Brentwood run $2,200-$5,000 per opening, and glass-heavy walls above 40 square feet are priced per panel.
How we do it
We measure the structural opening in three axes, confirm the load path and header, order the panels with the correct split and mullion layout, and install with glass cups and a two-person crew where the weight requires it.
What Custom & Geometric Windows Costs in Brentwood
| Item | Typical range in Brentwood |
|---|---|
| Arched or curved window, standard radius | $1,500-$3,800 per opening |
| Oversized custom opening, per panel | $2,200-$5,000 per panel |
| Custom geometric window, laminated glass | $1,800-$4,500 per opening |
Can you match the odd-shaped window already in my Brentwood home?
Yes. We template the existing opening and order a made-to-measure unit, not a stock rectangle. The written quote shows the exact dimensions and the radius or angle so you can check it against the old window. Call (509) 265-6387 to start.
How long does a custom window take to get?
Custom geometric windows are made to the template and typically take three to six weeks from order to delivery. We can pre-order once the opening is measured, so the wait is on the glass, not the install crew.

Under the Haven Standard, the measured survey and the written quote are the same document, so the number you approve is the number you pay.
