AfterWindows & Doors in San Clemente, CA
Window installation in San Clemente runs $750-$1,600 per opening for standard replacement units, and most jobs take one to three days once materials arrive. What makes San Clemente different is the housing stock itself: 1920s Spanish Colonial Revival homes with arched stucco openings sit next to bluff-top mid-century ranch houses and 1990s Talega tracts, all of them facing salt-laden Pacific wind that corrodes aluminum frames and destroys weatherstripping far faster than homeowners expect. Call (509) 265-6387 for a written price before any work starts.
Why San Clemente Homes Are Different
San Clemente’s oldest neighborhoods around Avenida del Mar and the historic T-Zone were built in the 1920s and 1930s as Spanish Colonial Revival originals with stucco walls, arched window openings, and decorative framing that standard replacement windows simply do not fit. Many of those homes still have their original steel casement windows, and by now those frames are usually rusted through where they meet the stucco. A pocket replacement is rarely an option; the full frame has to come out.
Layered on top of that, the city sits on Pacific-facing marine terraces where consistent onshore winds drive salt air directly into west- and south-facing elevations year-round. That salt air degrades aluminum frames, corrodes hardware, and breaks down weatherstripping and IGU seals at a rate that routinely surprises homeowners who moved from inland Orange County cities like Aliso Viejo or Laguna Niguel. The near-constant marine layer also traps moisture against stucco window sills, so improper flashing during installation becomes dry-rot and stucco delamination within a few years. In Forster Ranch and Talega, the 1990s and 2000s tracts have their own issues: builder-grade vinyl units with failed seals and underperforming U-factors that were never matched to coastal conditions.
Our Main San Clemente Services
Most San Clemente homeowners call us about two things: doors that have swollen or corroded in the salt air, and windows that have outlived their seals. Both jobs start with a measured survey you keep, and the written quote cannot differ from that document.
Door Installation in San Clemente
Entry doors in San Clemente take a beating from the marine layer, and west-facing doors in the historic T-Zone corrode fastest. We replace them with full-frame tear-outs that address the flashing and sill damage hiding underneath, not just the visible door slab. Door Installation in San Clemente covers the specifics of entry, patio, and French door work in this city’s stucco and wood-framed homes.
Window Replacement in San Clemente
Whether it’s a 1920s steel casement rusted into an arched opening or a 2005 vinyl double-hung in Talega with a blown seal, window replacement here means matching the unit to the era of the house. The T-Zone requires custom-radius units or wood windows; Forster Ranch needs better glazing, not just new frames. Window Replacement in San Clemente has the full breakdown of what replacement looks like block by block.

BeforeAfterWindow Installation in San Clemente
Window installation in San Clemente is dominated by two realities: original 1920s and 1930s homes with arched, non-rectangular rough openings, and relentless salt air that has corroded existing aluminum and steel frames. Standard off-the-shelf vinyl double-hungs do not fit the Ole Hanson-era openings and do not hold up to the coastal corrosion cycle. For the full scope of our Window Installation work, including the measured-survey process and written quoting, see that page.
Single & Double Hung Windows
Signs you need it
Sashes that stick, rattle in the wind, or show white corrosion powder at the corners mean the frame is failing, not just the glass.
What it costs in San Clemente
Single and double hung windows in San Clemente typically run $750-$1,600 per opening installed, depending on frame material and whether the opening needs full-frame work.
How we do it
We measure the rough opening, write the price before any work starts, remove the old unit down to the studs where needed, install the new hung window with proper flashing, and leave a documented photo record.
Casement Windows
Signs you need it
Crank mechanisms that seize up from salt corrosion and frames that no longer seal tight against the jamb are the two clearest signals.
What it costs in San Clemente
Casement windows in San Clemente run $850-$1,900 per opening, with the higher end reflecting custom sizing for older arched or non-standard rough openings.
How we do it
We remove the old casement and its corroded hardware, inspect the surrounding stucco for moisture intrusion, install the new unit with marine-grade fasteners, and document everything with photos.
What Window Installation Costs in San Clemente
| Item | Typical range in San Clemente |
|---|---|
| Single hung window | $750-$1,200 per opening |
| Double hung window | $850-$1,600 per opening |
| Casement window | $850-$1,900 per opening |
How long does window installation take in San Clemente?
One to three days for most single-openings-to-whole-home jobs, depending on the number of windows and whether full-frame tear-outs are required in older stucco homes.
Does San Clemente require permits for window installation?
Yes, most window replacement in San Clemente requires a building permit, especially on the historic T-Zone homes where design review also applies. We pull permits and pass inspections.
Impact Windows & Doors in San Clemente
Impact-rated windows and doors in San Clemente are not required by code on every home, but they are the only glazing that holds up to both the salt-air corrosion cycle and the debris-driven wind events that hit Pacific-facing elevations. Bluff-top homes and west-facing rooms get hit hardest, and standard annealed glass simply does not survive a direct hit from windborne debris. See our Impact Windows & Doors hub for product specs and testing standards.
Impact-Resistant Windows
Signs you need it
If your current windows show pitting, rust on the frames, or you can hear wind whistling through the seals, an impact-rated replacement is the fix for both security and envelope integrity.
What it costs in San Clemente
Impact-resistant windows in San Clemente run $1,100-$2,400 per opening, with laminated glass and reinforced frames accounting for most of the premium.
How we do it
We measure the rough opening, write the price, install the impact-rated unit with marine-grade flashing, and provide the Miami-Dade or ASTM test documentation for your records.
Horizontal Roller & Sliding Impact Windows
Signs you need it
Roller tracks that grind or jam from salt residue, plus visible frame pitting, mean the unit has reached the end of its coastal service life.
What it costs in San Clemente
Horizontal roller and sliding impact windows in San Clemente run $1,200-$2,500 per opening, with larger three-lite configurations at the upper end.
How we do it
We pull the old roller unit, inspect the sill for dry-rot behind the stucco, install the impact-rated replacement with new tracks and rollers, then document the finished opening.
What Impact Windows & Doors Costs in San Clemente
| Item | Typical range in San Clemente |
|---|---|
| Impact-resistant window | $1,100-$2,400 per opening |
| Horizontal roller impact window | $1,200-$2,500 per opening |
| Impact sliding glass door | $2,800-$6,500 per door |
Are impact windows worth the cost in San Clemente?
For bluff-top and west-facing homes, yes. Impact windows replace the corroded frame and the fragile glass in one step, eliminating both the salt-air failure point and the storm-debris risk simultaneously.
Do impact windows change how my San Clemente home looks?
No. Modern impact units from PGT and CGI come in flush-mount and arch-top configurations that read identically to standard windows from the curb, including custom-radius options for T-Zone homes.
Energy-Efficient Windows in San Clemente
Energy-efficient windows in San Clemente are less about cold winters and more about the marine layer: the constant humidity means your air conditioner runs more than your heater, and low-E glass cuts solar gain on those long west-facing afternoons. Homes in Forster Ranch and Talega, built with builder-grade vinyl in the late 1990s and early 2000s, gain the most from a U-factor and SHGC upgrade. Our Energy-Efficient Windows page explains the full spec sheet.
Low-E & Argon Gas Glass
Signs you need it
Rooms that overheat by 3 p.m. in summer, plus condensation between the panes, mean the original low-E coating has failed or was never installed.
What it costs in San Clemente
Low-E with argon gas glass in San Clemente runs $850-$1,800 per opening, depending on the frame material and whether it’s a pocket or full-frame replacement.
How we do it
We measure the opening, spec the correct U-factor and SHGC for the home’s orientation, install the unit with proper flashing, and provide the glass performance documentation.
ENERGY STAR Replacement Windows
Signs you need it
Drafty sashes and glass that radiates heat into the room on summer afternoons are the two most common complaints we hear from San Clemente homeowners.
What it costs in San Clemente
ENERGY STAR replacement windows in San Clemente run $800-$1,700 per opening, with the tax-credit-eligible units at the mid-to-upper end of that range.
How we do it
We verify the existing rough opening, write the price, remove the old unit, install the ENERGY STAR-rated replacement with a full weather barrier, and photograph the completed work.
What Energy-Efficient Windows Costs in San Clemente
| Item | Typical range in San Clemente |
|---|---|
| Low-E with argon gas window | $850-$1,800 per opening |
| ENERGY STAR replacement window | $800-$1,700 per opening |
| Insulated laminated glass window | $900-$1,900 per opening |
What U-factor should I look for in San Clemente?
For coastal Southern California, a U-factor of 0.30 or lower and a SHGC of 0.25 or lower is the sweet spot for west- and south-facing elevations. We spec exact numbers for each opening.
Will energy-efficient windows actually lower my San Clemente electric bill?
Usually, yes, especially on homes where the AC runs through the afternoon. Solar gain through west-facing glass is the single largest driver of cooling load in San Clemente.
Sliding & Patio Doors in San Clemente
Sliding and patio doors in San Clemente fail in a predictable pattern: the salt air corrodes the roller hardware and the track, the panel starts dragging, and eventually the door won’t latch or seal. Homes with west-facing patios get hit hardest, and the original aluminum sliders on 1970s and 1980s bluff homes are usually beyond repair by now. For the full product and spec breakdown, see our Sliding & Patio Doors page.
Patio Doors
Signs you need it
A door that scrapes, sticks, or lets daylight through the closed seam has rotted or corroded rollers and a fatigued frame.
What it costs in San Clemente
Patio door replacement in San Clemente runs $2,200-$5,800 per door, with multi-panel sliders at the upper end.
How we do it
We remove the old panel and frame, inspect the sub-sill for dry-rot, install the new door with fresh flashing, and leave a photo record of the entire opening.
Impact Sliding Glass Doors
Signs you need it
If the existing slider is aluminum with visible pitting, or if the glass is not laminated, it will not hold up to a windborne debris hit on a Pacific-facing elevation.
What it costs in San Clemente
Impact sliding glass doors in San Clemente run $2,800-$6,500 per door, with the laminated glass and reinforced frame accounting for the premium.
How we do it
We measure the full rough opening, write the price, install the impact-rated slider with marine-grade seals, and provide the impact test documentation.
What Sliding & Patio Doors Costs in San Clemente
| Item | Typical range in San Clemente |
|---|---|
| Patio door replacement | $2,200-$5,800 per door |
| Impact sliding glass door | $2,800-$6,500 per door |
| Impact French patio door | $3,000-$7,000 per door |
Why does my San Clemente patio door stick every summer?
Salt air corrodes the roller bearings and the aluminum track, and the marine layer keeps moisture against the sill, swelling the frame. Cleaning the track helps temporarily, but the corrosion underneath continues.
Can you replace just the patio door panel, not the frame?
Sometimes, but in San Clemente it’s rarely the right call. The frame is usually where the corrosion and dry-rot started, and a new panel in a failing frame repeats the problem within a few years.
Impact Garage Doors in San Clemente
Impact garage doors in San Clemente are the most overlooked opening in the house. A standard builder-grade roll-up door on a Pacific-facing garage will rattle, bow, and eventually fail under sustained wind load, and the salt air accelerates every moving part. See our Impact Garage Doors page for load ratings and wind-code details.
Hurricane-Rated Garage Doors
Signs you need it
If you can see daylight through the garage door tracks, hear the door rattle in a stiff onshore breeze, or find rust flakes on the hinges, the existing door is not doing its job.
What it costs in San Clemente
Hurricane-rated garage doors in San Clemente run $2,400-$5,800 per door, depending on width, insulation, and wind-load rating.
How we do it
We measure the garage opening, write the price, remove the old door and track, install the rated replacement with reinforced hardware, and document the finished door with photos.
Wind-Load Code Compliance
Signs you need it
If your garage door predates the current wind-load codes or shows visible bowing under pressure, it fails the basic compliance test.
What it costs in San Clemente
Wind-load code compliance retrofits for garage doors in San Clemente run $1,200-$3,500 per door, covering reinforcement hardware and bracing systems.
How we do it
We assess the existing door against the current wind-load tables for San Clemente, install the required reinforcement, and provide the compliance documentation for your records.
What Impact Garage Doors Costs in San Clemente
| Item | Typical range in San Clemente |
|---|---|
| Hurricane-rated garage door | $2,400-$5,800 per door |
| Energy-efficient garage door | $1,800-$4,200 per door |
| Wind-load code retrofit | $1,200-$3,500 per door |
Does my San Clemente home need an impact garage door?
If your garage faces west or south on a bluff or open terrace, the answer is usually yes. The garage door is the largest single opening in most homes and the most likely to fail under wind load.
Will an impact garage door last longer in the salt air?
Yes. Rated doors use galvanized or stainless hardware and corrosion-resistant track systems, which is the main reason they outlast standard doors in San Clemente’s marine environment.
Custom & Geometric Windows in San Clemente
Custom and geometric windows are not an option in San Clemente’s historic T-Zone, they are a requirement. The Ole Hanson-era homes around Avenida del Mar have arched, curved, and decorative openings that were never designed for rectangular units, and the city’s design-review process actively discourages converting them. For the full product range and process, see our Custom & Geometric Windows page.
Arched & Curved Windows
Signs you need it
Rust lines at the base of an existing arched steel frame, or a visible gap where the frame meets the stucco arch, mean the original unit has corroded through.
What it costs in San Clemente
Arched and curved windows in San Clemente run $1,500-$3,500 per opening, with custom radius work and full-frame removal at the upper end.
How we do it
We field-measure every arc and radius of the existing opening, produce a written price, fabricate the custom unit to match, and install it with careful flashing around the arch.
Oversized Openings
Signs you need it
Fixed glass panels that bow, cloud, or crack on bluff-top homes, or picture windows that rattle in their frames during wind events, are the usual signals.
What it costs in San Clemente
Oversized and custom openings in San Clemente run $1,800-$4,500 per opening, with structural framing and crane-assisted installation on upper floors adding cost.
How we do it
We measure the rough opening and sightlines, write the price, engineer the glazing for the wind load, install the unit with reinforced framing, and photograph the finished opening.
What Custom & Geometric Windows Costs in San Clemente
| Item | Typical range in San Clemente |
|---|---|
| Arched or curved window | $1,500-$3,500 per opening |
| Geometric or shaped window | $1,200-$3,000 per opening |
| Oversized opening | $1,800-$4,500 per opening |
Can I replace an arched window with a rectangular one in San Clemente?
In the historic T-Zone, the city’s design review discourages it, and the stucco work required to alter the opening usually negates any cost savings. Custom-radius units are the better path.
How long does a custom window take in San Clemente?
Fabrication for custom-radius and geometric units typically runs three to six weeks, then installation is one to two days. We write the timeline into your quote before any work starts.

What San Clemente Customers Say
"The survey measurements and the quote were the same piece of paper. Nothing changed on install day, which is not what happened with the two other companies we had out."
- Annette R."Replaced eight windows. They showed me the U-factor on the units they were actually fitting rather than the brochure numbers."
- Kofi B."They photographed the rotten sill they found under the old frame before replacing it, and the extra cost was agreed in writing before they carried on."
