CWS Construction in San Diego, CA | Mason Remodeling Co San Diego
We provide independent CWS construction service across San Diego, with a focus on window replacement, impact window installation, and roof repair. What sets our crew apart locally is that we actually understand how San Diego’s salt fog, canyon slopes, and older stucco housing make CWS products fail differently here than they would in, say, Temecula. We’re not affiliated with CWS or any manufacturer. We’re the independent crew that fixes what this coastal climate does to their windows and doors. Call (619) 673-9302 any time.
Why San Diego Residents Choose Us for CWS Service

CWS windows and doors show up in a lot of San Diego homes, especially the mid-century ranches and stucco tract houses built across Clairemont, Allied Gardens, and the inland mesas. Our crews work on those products daily, so we know exactly what a CWS Series 1000 Single-Hung frame looks like when it’s been eaten by decades of morning marine layer. We also know when a patch job is smarter than a full replacement, and we’ll tell you straight which one you need.
Isaac Pruett grew up in Los Angeles and picked up a framing hammer long before he sat in a classroom. But it was his time at Los Angeles Trade-Technical College that sharpened his eye for structural detail. For years now, he and our crew have worked all over San Diego County, from gut-renovating kitchens near Balboa Park to overhauling bathrooms in houses older than most of his tools. That local experience means we’ve seen the same failing CWS window details repeated across dozens of San Diego neighborhoods, and we know what to look for before the damage spreads.

Common CWS Construction Problems We Solve in San Diego
Here’s what we see most often on CWS products in San Diego homes:
- Corroded aluminum window frames near the coast. In beach neighborhoods like Pacific Beach and La Jolla, the salty air attacks CWS aluminum frames relentlessly. Pitting starts at the corners and bottom rails, then cracks form. Once the frame cracks, water gets into the stucco and the rot begins.
- Failed weeps and flashing behind original CWS installations. Many 1950s and 60s homes in Clairemont and Allied Gardens still have their original CWS windows with missing or blocked weep holes. That’s been quietly funneling rainwater into the wall cavity for decades, and we regularly find hidden wood rot when we pull those units out.
- Sticking or misaligned CWS sliding doors on hillside lots. Foundation settlement is common on San Diego’s canyon rims and sloped lots. A CWS Series 2000 Sliding Patio Door that drags or won’t latch properly is often a sign the house has settled, not just that the rollers are worn. We check both before we quote.
- Fogged insulated glass in original CWS windows. San Diego’s warm summers make failed seals easy to spot: condensation trapped between the panes. That means the insulating gas is gone and the window’s energy performance is shot. We replace the glass pack when the frame is still sound.
- Rusted hardware on CWS French doors near the water. Series 4000 French Doors in coastal homes often show corroded hinges, handles, and lock sets from salt air. The hardware fails before the door does, and we carry OEM-equivalent replacements that match the original profiles.
CWS Service in San Diego: What Local Conditions Mean for Your Equipment
San Diego’s hillside canyon lots create a problem flat-lot neighborhoods never face. On a slope, water moves downhill through your wall system, not just over it. Our crews have worked on CWS door replacements in Mission Hills and Point Loma where the city required erosion control and foundation inspection before we could even pull the old frame. That’s a San Diego reality, not a CWS one. A simple patio door swap can trigger slope stabilization and drainage correction, because the city wants to know the hillside won’t erode once the opening is disturbed. We’ve handled those permits and inspections enough times that they don’t slow us down. If you live on a canyon rim or a sloped street in Point Loma, budget for that extra step and find a crew that’s done it before. Most window crews in flat inland areas never touch this kind of work.
CWS Models & Products We Service in San Diego
Our crews work on the full CWS residential line: Series 1000 Single-Hung Windows, Series 2000 Sliding Patio Doors, Series 3000 Casement Windows, and Series 4000 French Doors. On repair jobs, we use OEM-equivalent glass packs, weatherstripping, and hardware matched to the original CWS frame profiles. That means the replacement parts fit the way the originals did, not like a generic aftermarket guess. When we quote a repair, we’re clear about what gets replaced and what gets restored. And when corrosion or frame damage has gone too far, we’ll recommend a full replacement. We’re not going to patch a rotted aluminum frame and call it done. That’s dishonest, and it costs you more in the long run. For the windows and doors we replace, you can read more about our approach on our CWS sales & service page.

AfterCWS Service Pricing in San Diego
| Service | San Diego Price Range |
|---|---|
| Window Replacement | $5,310 – $17,700 |
| Impact Window Installation | $9,440 – $29,500 |
| Roof Repair | $470 – $2,125 |
What drives the cost in San Diego is the condition of the existing framing, whether the house sits on a slope that needs drainage correction, and how much salt corrosion has crept into the surrounding stucco. A flat-lot window swap costs less than a hillside door replacement that pulls the city into it. Every project gets a written line-item price before we start, so you know exactly what you’re paying. Call (619) 673-9302 for a free estimate, and we’ll walk the job with you.

FAQs – CWS Construction in San Diego
Do you replace just the glass in my CWS windows, or should I replace the whole frame?
Glass replacement makes sense when the insulated glass unit has failed but the frame is straight and shows no corrosion. A fogged CWS window in El Cajon is a glass-pack problem. A pitted, cracked CWS frame in Pacific Beach is a frame-replacement problem. We’ll tell you which one you have. Call (619) 673-9302 for a straight answer and a free estimate.
Are your CWS window repairs compliant with San Diego’s coastal construction rules?
Yes. When a job falls within a coastal overlay or hillside review zone, we pull the permits, submit the erosion control plans, and pass the inspections before we finish. We’ve done this work in Mission Hills and Point Loma enough times to know what the city wants before we dig the first hole.
Can you fix a CWS sliding door that’s hard to open and lets drafts in?
Usually, yes. We first check whether the house has settled and the track is out of alignment, which is common on San Diego hillside lots. If the frame is sound, we replace rollers, adjust the track, and install new weatherstripping matched to your CWS Series 2000 profile. If the frame is twisted, we’ll quote a full replacement.
Why does my CWS window have condensation between the panes? Is that a San Diego thing?
Condensation between the panes means the seal has failed and the inert gas has escaped. It happens everywhere, but San Diego’s wild temperature swings between cool coastal nights and hot inland afternoons stress seals faster than a stable climate. The fix is replacing the glass pack, or the whole unit if the frame is also compromised.
Do you work on CWS French doors with rusty hardware near the beach?
We do. Rusted hinges, handles, and lock sets on Series 4000 French Doors are common in La Jolla, Pacific Beach, and other salt-air neighborhoods. We replace the hardware with OEM-equivalent parts and check the surrounding frame for the same corrosion that ate the handles. For a full line of CWS products, see our CWS sales & service page.
