AfterWindows & Doors in Union City, CA
Window and door replacement in Union City, CA typically runs between $650 and $3,200 per opening depending on the product and what the existing frame looks like once we open the wall. Most jobs here start with original aluminum sliders from the 1960s through 1980s that have corroded in the marine air that pours through the Dumbarton Bridge gap. The written quote we hand you after the measured survey is the same document we build from, so the price on paper is the price you pay. Call (509) 265-6387 to schedule a measured survey.
Why Union City Homes Are Different
Union City’s western flatlands sit at the inland end of the Dumbarton Bridge marine corridor. Prevailing westerly winds push salt-laden fog directly into neighborhoods west of I-880, and that air does measurable damage to aluminum window frames and steel door hardware. We regularly find sliders on 1960s and 1970s homes so oxidized they have fused to their anchor bolts, and the rough-opening framing behind them has absorbed enough moisture that sistering new jack studs is nearly standard on those jobs. The old Alvarado village area east of the tracks has its own pattern: pre-1950s wood-frame bungalows where sash rot and deteriorated door jambs are the dominant failure, not aluminum corrosion. Homes in the Decoto corridor fall between the two, mixing hollow-core entry doors past service life with single-pane sliders that fog and sweat through every cold season. A California Title 24 compliance upgrade from single-pane aluminum to dual-pane vinyl or fiberglass rides along with almost every replacement we quote here, which is the defining project type in Union City’s windows-and-doors market.
Our Main Union City Services
Two services account for most of the work Union City homeowners call us about: door replacements that tighten up a failed hollow-core or corroded entry, and full window replacements that solve the single-pane aluminum problem in one pass. Each has its own dedicated page with the detail, pricing, and local conditions that apply.
Door Installation in Union City
Doors in Union City fail differently than windows: the marine air attacks hinges, thresholds, and steel frames, while the original hollow-core slabs from the 1960s and 1980s offer almost no thermal or security performance. We replace entry, patio, and interior doors with measured, written pricing before any tool is lifted. Door Installation in Union City covers the full scope, from rotted jamb repair in Alvarado bungalows to full frame replacement on newer tract homes.
Window Replacement in Union City
Replacing original single-pane aluminum sliders is the single most common project we quote in Union City, because the Dumbarton corridor salt air has already done its damage by the time the fog condenses on the inside of the glass. Full tear-out and retrofit both apply depending on rough-opening condition, and every job includes the measured survey the customer keeps. Window Replacement in Union City walks through what the work looks like on the ground, including what we find behind corroded frames.

BeforeAfterWindow Installation in Union City
Window installation in Union City most often means tearing out original single-pane aluminum sliders on 1960s through 1980s tract homes, then setting dual-pane vinyl or fiberglass units into rough openings that frequently need new jack studs because chronic marine-layer moisture has softened the framing. We measure every opening, write the price from that survey, and hand you the document before any work starts. That survey is the same document our crews build from under the Haven Standard, including its first clause: the quote and the measurement are one record. See the scope of our Window Installation work nationwide.
Single & Double Hung Windows
Signs you need it
Sashes that stick, drop, or refuse to stay open, plus condensation between panes on original single-glazed units.
What it costs in Union City
Single and double hung replacements in Union City typically run $450 to $1,600 per window depending on size, frame material, and whether the rough opening needs reframing.
How we do it
We remove the old sash and frame, inspect and sister any compromised jack studs, set the new unit plumb and square, insulate the rough opening, and flash it before trimming out the interior.
Horizontal Roller Windows
Signs you need it
Rollers that grind or bind, tracks packed with corrosion scale, and frames that have bowed enough to let fog-drift air through the weatherstripping.
What it costs in Union City
Expect $500 to $1,300 per horizontal roller window in Union City, with the higher end covering units that require sistering rotted framing.
How we do it
We pull the existing frame, sister any damaged framing, set the new roller unit in a sealed opening, then photograph the finished install as part of the standard record.
Casement Windows
Signs you need it
Cranks that slip or snap, hinges that have corroded stiff from marine exposure, and glass that no longer seals against the frame when closed.
What it costs in Union City
Casement window installation in Union City commonly falls between $560 and $1,700 per opening, driven by hardware grade and whether the rough opening needs structural repair.
How we do it
We remove the old operator and sash, set the new casement into a flashed and insulated rough opening, and adjust the hardware so the sash seats evenly on all four sides.
Awning & Hopper Windows
Signs you need it
Hinges that have seized, glass that fogs from failed seals, and frames that no longer stay open without propping.
What it costs in Union City
Awning and hopper window replacement in Union City typically ranges from $400 to $1,100 per window, with hoppers on the lower end and larger awnings on the upper end.
How we do it
We remove the old frame and sash, prep the rough opening, install the new unit with proper flashing and insulation, and verify the venting operation before we leave.

Impact Windows & Doors in Union City
Impact windows and doors in Union City are a wind-debris and security upgrade layered onto the same corrosion problem that affects every aluminum opening here. Homes west of I-880 catch the direct Dumbarton marine push, and original single-pane sliders offer nothing against wind-driven debris during winter storms or the salt fog that eats frames year-round. We specify impact-rated glazing and reinforced frames from manufacturers like CGI and PGT based on the opening’s exposure, not on what is in stock. That is the same discipline behind our Impact Windows & Doors line overall.
Impact-Resistant Windows
Signs you need it
Original single-pane aluminum that bows under hand pressure and single-glazed glass that would shatter from thrown debris.
What it costs in Union City
Impact-resistant window replacement in Union City typically ranges from $1,200 to $2,800 per opening, with laminated glass and reinforced frames driving the upper end.
How we do it
We measure the existing opening and exposure, specify a laminated impact unit with the correct design pressure rating, then remove the old frame, prep the rough opening, and set the new unit with structural anchoring.
Hurricane Impact Windows
Signs you need it
Living west of I-880 where winter storm gusts and wind-driven debris are a question of when, not if, and original glass offers no barrier.
What it costs in Union City
Hurricane impact windows in Union City commonly fall between $1,300 and $2,900 per opening, depending on size, design pressure, and frame material.
How we do it
We verify the opening dimensions and wind-load requirements, order a rated impact unit, and install it with structural fasteners and full flashing per the manufacturer’s engineering.
What Impact Windows & Doors Costs in Union City
| Item | Typical range in Union City |
|---|---|
| Impact-resistant window | $1,200 - $2,800 per opening |
| Hurricane impact window | $1,300 - $2,900 per opening |
| Impact sliding glass door | $2,600 - $7,500 per unit |
Are impact windows worth it in Union City?
For homes west of I-880, impact glazing closes the largest vulnerability to wind-driven debris and salt-air corrosion in one product. It also reduces exterior noise. Call (509) 265-6387 for a written quote.
Do impact windows meet California building code?
Yes, rated impact units satisfy structural and glazing requirements under current California codes when specified for the correct design pressure. We handle the documentation. Call (509) 265-6387 to schedule a survey.
Energy-Efficient Windows in Union City
Energy-efficient windows in Union City solve the cold-season condensation problem that original single-pane aluminum can’t avoid when Dumbarton fog settles into the low western neighborhoods. Dual-pane insulated glass with low-E coatings cuts the interior sweating and the heat loss through the frame, which matters because Title 24 upgrades are nearly automatic here when original sliders come out. We replace old units with rated glass specified by U-factor and SHGC, not by what happens to be available. That is the same approach we take across our Energy-Efficient Windows line.
Low-E & Argon Gas Glass
Signs you need it
Condensation forming on the inside of single-pane glass every winter morning and rooms that never hold a set temperature.
What it costs in Union City
Low-E argon-filled glass upgrades on Union City replacements generally add $35 to $110 per window over standard insulated glass.
How we do it
We specify the low-E coating and argon fill based on the home’s orientation and the opening’s exposure, then install the glass in a properly flashed and insulated frame.
ENERGY STAR Replacement Windows
Signs you need it
Original aluminum frames that are cold to the touch all winter and utility bills that climb every fog season while rooms stay drafty.
What it costs in Union City
ENERGY STAR-rated replacement windows for Union City homes typically run $500 to $1,600 each, before any structural repair to rough openings.
How we do it
We measure each opening, confirm the performance tier, write the quote, then install rated glass in a new or retrofitted frame with insulation and flashing.
What Energy-Efficient Windows Costs in Union City
| Item | Typical range in Union City |
|---|---|
| Low-E / argon glass upgrade | $35 - $110 per window |
| ENERGY STAR replacement window | $500 - $1,600 per window |
| Insulated laminated glass | $700 - $2,000 per window |
What U-factor should I look for in Union City?
A U-factor of 0.30 or lower works well for Union City’s fog-heavy winters, paired with a low-E coating to manage the summer heat gain through the Dumbarton corridor. Call (509) 265-6387 for glass package pricing.
Will energy-efficient windows stop the condensation?
Dual-pane insulated glass with a low-E coating eliminates the interior surface condensation that forms on single-pane aluminum when marine fog settles in. Call (509) 265-6387 to get your written quote.
Sliding & Patio Doors in Union City
Sliding and patio doors in Union City get hit from two directions: the salt air that corrodes rollers, tracks, and handles, and the original aluminum frames from the 1960s through 1980s that were never built to seal against fog-driven moisture. The result is a door that binds, leaks cold air at the threshold, and lets the Dumbarton marine layer into the house every evening. We replace full sliding units and framed patio doors with measured, written pricing before any tool is lifted. See our full Sliding & Patio Doors scope for the national picture.
Patio Doors
Signs you need it
A door that sticks at the bottom track, has a threshold that stays wet, and shows white corrosion scale on the rollers and the frame.
What it costs in Union City
Patio door replacement in Union City typically ranges from $1,200 to $4,500 per unit depending on width, material, and whether the framed opening needs structural repair.
How we do it
We pull the old slab and frame, inspect the rough opening for rot, sister framing as needed, then set the new door in a flashed and insulated opening with a sealed threshold.
Sliding Glass Door Replacement
Signs you need it
Rollers that grind and jump the track, glass that fogs, and an aluminum frame so oxidized it no longer holds the weatherstripping tight.
What it costs in Union City
Sliding glass door replacement in Union City commonly runs $1,400 to $4,800 per door, with the high end covering corroded anchors and rough-opening repair.
How we do it
We remove the old slider, sister any damaged framing, install a new unit with new rollers and track, and adjust it until the slab glides without binding.
What Sliding & Patio Doors Costs in Union City
| Item | Typical range in Union City |
|---|---|
| Patio door | $1,200 - $4,500 per door |
| Sliding glass door replacement | $1,400 - $4,800 per door |
| Screen door installation | $150 - $500 per screen |
How much does it cost to replace a sliding glass door in Union City?
Sliding glass door replacement in Union City usually falls between $1,400 and $4,800, with the final figure set by track corrosion and rough-opening condition. Call (509) 265-6387 for your written quote.
Can you fix my existing sliding door instead of replacing it?
You can often replace rollers and hardware on a functioning frame, but if the aluminum has corroded through or the rough opening has rot, full replacement is the honest fix. Call (509) 265-6387 for a measured assessment.
Impact Garage Doors in Union City
Impact garage doors in Union City protect the largest unbraced opening on the house from the same storm winds that push through the Dumbarton corridor every winter. The original single-layer steel doors on tract homes from the 1960s through 1980s were never engineered for wind-load compliance, and marine air has rusted their track hardware and hinges. We replace them with rated, reinforced doors specified by design pressure and wind-load code, not by whatever model is easiest to order. That is the standard we apply across our Impact Garage Doors line.
Hurricane-Rated Garage Doors
Signs you need it
A garage door that flexes visibly in winter wind, has rusted tracks, or carries no wind-load rating while the house sits west of I-880.
What it costs in Union City
Hurricane-rated garage door replacement in Union City typically runs $2,600 to $6,500 per door, depending on size, reinforcement, and operator integration.
How we do it
We measure the opening, confirm the wind-load requirement for the home’s exposure, then install a rated door with reinforced tracks, struts, and anchoring per the engineering.
Garage Door Replacement
Signs you need it
Panels dented or rusted through, springs that have been replaced multiple times, and a door that no longer seals against the jamb when closed.
What it costs in Union City
Garage door replacement in Union City generally falls between $1,200 and $4,000 per door, not including any opener or spring work.
How we do it
We remove the old door, inspect and reinforce the opening as required, install the new door with new track and hardware, and leave a photo record of the finished install.
What Impact Garage Doors Costs in Union City
| Item | Typical range in Union City |
|---|---|
| Hurricane-rated garage door | $2,600 - $6,500 per door |
| Standard garage door replacement | $1,200 - $4,000 per door |
| Wind-load code compliance upgrade | $500 - $2,000 per door |
Does Union City require wind-load-rated garage doors?
Current California codes require wind-load compliance for new garage door installations, and the Dumbarton corridor exposure makes the rating practical, not just legal. Call (509) 265-6387 to verify your opening’s requirements.
Can I keep my existing garage door opener?
Most openers can be kept if they are compatible with the new door’s weight and balance, which we verify during the measured survey. Call (509) 265-6387 for a written assessment.
Custom & Geometric Windows in Union City
Custom and geometric windows in Union City usually appear on the older Alvarado village bungalows and on mid-century split-levels where the original architects cut a shaped opening and standard replacement units no longer exist off the shelf. The marine air here has done the same damage to those custom wood sash frames it does to aluminum, so we build replacement units to the original sightlines, not to the nearest stock size. We then set them into openings that often need new jamb stock because chronic fog exposure has softened the wood. That is the standard of our Custom & Geometric Windows line.
Arched & Curved Windows
Signs you need it
Arched or curved sash with rot at the spring point, cracked glazing, or a frame that has shifted out of square from moisture cycling.
What it costs in Union City
Arched and curved replacement windows in Union City typically run $1,500 to $4,500 per opening, driven by template work, radius, and frame repair.
How we do it
We template the existing opening, spec the radius from the measured curve, then fabricate the sash and frame to match the original sightline before installing it into a repaired rough opening.
Geometric & Shaped Windows
Signs you need it
Angled, hexagonal, or trapezoidal glass that has broken seals, wood trim that has rotted, or a shape that no standard manufacturer still catalogs.
What it costs in Union City
Geometric and shaped window fabrication in Union City commonly falls between $1,100 and $3,800 per unit, depending on complexity and glazing.
How we do it
We create a template of the opening, confirm the glass package, fabricate the unit to the measured shape, and set it into a flashed and sealed frame built to match the original sightline.
What Custom & Geometric Windows Costs in Union City
| Item | Typical range in Union City |
|---|---|
| Arched or curved window | $1,500 - $4,500 per opening |
| Geometric or shaped window | $1,100 - $3,800 per unit |
| Oversized custom opening | $2,500 - $7,000 per opening |
Can you match the original window shape on my Alvarado bungalow?
Yes, we template the existing opening and fabricate to the original sightline, including arched and curved shapes that stock manufacturers have discontinued. Call (509) 265-6387 for template pricing.
How long does a custom window take?
Custom and geometric windows typically take four to eight weeks from template to installation, depending on fabrication complexity and glazing. Call (509) 265-6387 to see current lead times.

What pushes a Union City price toward the top of these ranges is nearly always the rough opening: decades of Dumbarton marine air rots jack studs and fuses corroded anchors, which adds framing labor that a phone quote can’t see. Our measured survey finds it on paper and the written price includes it, so the number you are quoted is the number on the invoice.
