Mason Remodeling Co Los Angeles has spent years working on CWS windows and patio doors in Van Nuys, and we’re not the manufacturer’s affiliate or an authorized dealer. We’re an independent service provider, which means we recommend what actually works for your house, not what a brand rep tells us to push. Our CWS sales & service experience covers everything from original 1950s aluminum sliders to modern vinyl retrofit windows.
Why Van Nuys Residents Choose Us for CWS Service
Most Van Nuys homes were built between 1945 and 1965, and plenty of them still have their original CWS aluminum windows, the ones with the thin anodized coating that’s now worn down to bare metal in spots. We know these windows because we’ve pulled hundreds of them out of stucco openings on Vanowen Street, Kester Avenue, and the blocks around Van Nuys Airport. We also track how CWS materials behave through Southern California’s temperature swings, so we can diagnose problems that a General Contractor - Van Nuys might miss.
Isaac Pruett, our owner, grew up in the San Fernando Valley and spent weekends watching his uncle rebuild houses on Roscoe Boulevard. That’s where he learned to spot the difference between a window that needs hardware and a window that needs to come out. Under his direction, every crew member who comes to your door is background-checked and identity-verified, and you’ll get their name and photo before they arrive. That’s the Threshold Standard, and we’ve held to it since 2004.

Common CWS Construction Problems We Solve in Van Nuys
- Hard water mineral buildup in older CWS frames. Van Nuys tap water carries enough dissolved minerals to leave white crust inside window tracks, especially on north-facing units that never fully dry after winter rains. The buildup jams sashes and breaks weatherstripping seals.
- Santa Ana grit in CWS slider tracks. When the winds blow through the Sepulveda Basin, they push sand and fine dust into window tracks on exposed lots. Rollers wear down fast, and sliders start to grind instead of glide.
- Thermal failure on original CWS aluminum windows. The anodized coating on 1950s frames thins over decades. Condensation forms on the glass, drywall stains appear around the openings, and the windows lose whatever insulating value they once had.
- Slab settlement throwing CWS patio doors out of square. Post-war Van Nuys homes sit on flat, sandy-loam lots, and slabs move. Patio door frames rack out of alignment, doors stick, and air leaks open up along the top and bottom.
- Stucco cracking around CWS window corners in summer. The semi-arid heat expands stucco and window frames at different rates. By August, you’ll see hairline cracks radiating from window corners on south-facing walls.
CWS Service in Van Nuys: What Local Conditions Mean for Your Equipment
Van Nuys has one of the highest concentrations of original post-war aluminum slider windows in Los Angeles, and you can see them on Vanowen Street between Sepulveda and Kester, block after block of near-identical 1950s ranchers with the same tired window frames. What’s underneath matters more. Many of those homes sit on slabs with failing post-tension cables, a signature Van Nuys retrofit condition that shifts window and door openings out of square over time. If you’re replacing CWS windows on one of these houses, the installer has to re-square each rough opening before the new frame goes in. Skip that step and the new window binds within a year. Our crew replaced seven aging CWS aluminum sliders on a 1954 rancher off Vanowen Street near the airport. The frames had warped from slab settling and the tracks were packed with decades of Santa Ana grit. We re-squared every opening, installed new CWS vinyl sliders with stainless rollers, and sealed the perimeter to stop air leaks before the winter rains hit.
CWS Models & Products We Service in Van Nuys
We work on the full CWS residential line in Van Nuys: the Standard Vinyl Window Series, Classic Aluminum Window Series, and Premium Wood-Clad Window Series, plus the CWS Sliding Patio Door Series. For hardware and weatherstripping, we use genuine CWS replacement parts whenever they’re available. For glass units, we often recommend quality aftermarket options, they deliver better energy performance at a lower cost than OEM glass on older models. When frames are severely corroded or seals have failed after 20-plus years, we’ll tell you straight that full replacement makes more sense than patching piece by piece. We keep common CWS hardware and weatherstripping stocked locally so most Van Nuys jobs don’t wait on shipping.

FAQs – CWS Construction in Van Nuys
Original CWS aluminum frames lose thermal performance as the anodized coating wears thin, which lets cold air conduct straight through the metal. Combined with Van Nuys’s cool, damp winter mornings, that produces condensation on the glass and a cold draft you can feel standing nearby. The fix is usually replacement with modern vinyl or composite frames. Call (213) 632-5711 and we’ll assess your windows for free.
Yes. Sticking after rain usually means the frame has shifted from slab settlement, or the track has accumulated grit and mineral deposits. We re-square the door, replace worn rollers, and clean and reseal the track. If the frame is too far gone, we’ll quote a full slider replacement. Call (213) 632-5711 for an exact price.
Impact windows make sense anywhere you want better security and noise reduction, and Van Nuys gets both: airport flight paths and street noise, plus Santa Ana wind gusts that rattle loose sashes. Impact-rated CWS windows also meet tougher building codes if you’re planning our Bathroom Remodeling in Van Nuys or another major remodel. We install them regularly across Van Nuys.
For a typical three-bedroom rancher with eight to twelve windows, plan on $8,000 to $22,000 depending on window count, sizes, and whether you need impact glass. Older Van Nuys homes sometimes need rough opening repairs before new windows go in, which adds labor. Call (213) 632-5711 and we’ll walk your house and give you a written number.
Van Nuys summer heat expands stucco and window frames at different rates, and south-facing walls get the worst of it. Cracks at window corners are usually a sign of thermal movement, not structural failure, but they should be sealed so winter rain doesn’t get behind the stucco. We can assess whether it’s cosmetic or something deeper with the window framing.
