PGT Construction in West Hills, CA | Mason Remodeling Co Thousand Oaks
We provide independent PGT construction service across West Hills, from impact window installation to roofing and structural work tied to those window openings. Call (805) 309-3386 for a written estimate. What makes our PGT work different here is that we treat every window as part of a larger hillside building envelope: the flashing, the stucco return, the roof termination above it, and the drainage moving water away from the foundation. Our crew has worked PGT products on West Hills homes for years, and we understand how the local fire-zone codes and 1970s hillside construction affect what actually holds up.
Why West Hills Residents Choose Us for PGT Service
We know PGT product lines well enough to diagnose problems without guessing, and we carry or can quickly source genuine PGT parts for the structural hardware that matters: rollers, balance systems, multi-point lock assemblies. For seals and weatherstripping, we will often recommend an aftermarket material that holds up better against West Hills heat and Santa Ana grit than the original. Isaac Pruett, owner of Mason Remodeling Co Thousand Oaks, grew up in Los Angeles and trained at Los Angeles Trade-Technical College before spending years on job sites across the region. That background means we approach PGT service as builders first: we are looking at how the window, the wall, and the roof work together, not just swapping parts.
We are an independent PGT service provider, not a manufacturer-authorized dealer. That independence matters. We have no incentive to push a full replacement when a repair is the honest call. Our 365-Day Done Right Promise covers the work we do: if something is not right within a year of completion, we make it right at no cost. You will also get a written price before any work starts, and a live person answers our phone around the clock, every day of the year.

Common PGT Construction Problems We Solve in West Hills
- Thermal bowing of aluminum frames on south-facing hillside exposures. West Hills summers push daytime temperatures well past what many original PGT WinGuard aluminum frames were sized for when installed decades ago. The metal expands, the sash drifts out of alignment, and you start feeling air leaks or fighting the lock. We see this regularly on homes south of Victory Boulevard where afternoon sun hits the glass hard. We can often re-square the sash and replace worn hardware rather than condemning the window.
- Stripped or corroded roller assemblies in Eze-Breeze sliding panels. Years of Santa Ana wind-blown grit works its way into the track, then winter rain adds moisture. The rollers grind down or seize. Panels that once slid easily become a two-handed job. We replace rollers and realign the track, and we will tell you honestly if the track itself has worn past the point where new rollers will last.
- Failed sealant joints around WinGuard frames on older stucco homes. Many West Hills homes built in the 1960s through the early 1980s have original stucco that has settled and cracked around window openings. The sealant bond breaks, water gets behind the flange, and you find staining on the interior sill after a heavy winter rain. This is a flashing and waterproofing problem as much as a window problem, and it is the kind of repair we think about from the builder’s side.
- Warped vinyl sashes on unshaded west walls. An unshaded west-facing wall in West Hills takes direct afternoon heat for hours in July and August. Vinyl sashes on those walls can warp enough to fail latching. Energy loss follows. We assess whether the sash can be corrected or whether replacement is the better long-term answer for that specific exposure.
- Undersized 1970s hillside drainage compromising window wells and foundation lines. This is a West Hills construction issue that shows up at the window. When original drainage systems cannot handle today’s stormwater flows, water pools against foundation walls and migrates into window openings. Fixing the window without addressing the drainage is a temporary patch. We look at both.
PGT Service in West Hills: What Local Conditions Mean for Your Equipment
West Hills sits within the Los Angeles Department of Building and Safety’s Very High Fire Hazard Severity Zone for hillside areas. That is a specific designation with real teeth: homes that are reroofed or newly built must use Class A roofing materials and ember-resistant vents. This requirement does not apply uniformly in neighboring communities like Woodland Hills or Canoga Park, which means a West Hills homeowner often faces a paired decision: replace the roof and the windows on the same property, in the same project. That is exactly the kind of work we handle as a General Contractor - West Hills. When we install PGT impact windows on a hillside home under a reroof, we integrate the window flashing and the roof underlayment as one continuous weather barrier. That coordinated approach matters more on a hillside pad off Vanowen Street than it does on a flat Valley lot, because water moves fast down those slopes and finds every gap.
PGT Models & Products We Service in West Hills
We service the PGT WinGuard Aluminum Series, WinGuard Vinyl Series, SpectraGuard Series, and Eze-Breeze sliding panel systems. For structural hardware like rollers, balance systems, and multi-point lock assemblies, we use genuine PGT replacement parts because those components carry load and affect warranty standing. For seals, weatherstripping, and operator covers, we often recommend high-quality aftermarket alternatives that better withstand West Hills heat and wind-blown grit. We keep common replacement parts for the model families above on hand for faster turnaround on West Hills service calls. If a full unit replacement is more cost-effective than repeated repairs, we will tell you that directly and put the numbers in writing before you decide.

FAQs – PGT Construction in West Hills
Yes. Homes in West Hills’ Very High Fire Hazard Severity Zone must meet stricter building code requirements, including Class A roofing and ember-resistant vents on new or reroofed homes, which means window installation here often needs to be coordinated with roofing work and fire-zone flashing details that are not required in nearby communities like Woodland Hills or Canoga Park. We install PGT windows with that code reality in mind, integrating the window flashing with the roof membrane and the surrounding stucco. Call (805) 309-3386 if you are planning a reroof and window replacement together so we can price it as one scope of work.
Thermal bowing happens because the aluminum frame expands in direct sun, and on a south-facing hillside exposure in West Hills that heat is relentless in summer. The bowing throws the sash out of alignment, causing air leaks and lock problems. In many cases we can correct the alignment, replace worn hardware, and restore function without a full West Hills Bathroom Remodeling-style replacement of the whole window. If the bowing is severe or the frame is fatigued from years of cycling, we will tell you replacement is the smarter long-term call and put the numbers in writing.
Yes. The sticking is usually the roller assembly: Santa Ana grit works into the track during dry months, then winter rain adds moisture and corrosion. We clean and realign the track, replace the rollers with genuine PGT parts, and the panel slides properly again. If the track itself is worn past serviceability, we will recommend replacement rather than charging you for a repair that will not last. Call (805) 309-3386 for a free estimate on Eze-Breeze repair.
For West Hills hillside homes in the VHFHSZ, Class A fire-rated roofing is required by code on new or reroofed homes. Within that requirement, concrete tile and standing seam metal are the two roof types we most often pair with PGT impact windows because they handle the thermal expansion of West Hills summers and the water flow of winter storms without degrading the flashing joints where roof meets window. We install both and will price the roof and window scope together if they are being done on the same project.
For structural hardware like multi-point lock assemblies, balance systems, and rollers on 1980s WinGuard windows, genuine PGT parts are often still available or can be sourced through our suppliers. The seals and weatherstripping from that era are usually better replaced with modern aftermarket materials that handle West Hills heat and grit better than the originals. We will always tell you exactly what we are using and why, and whether the age of the window makes repair or replacement the smarter financial choice.
