A typical PGT patio door install in Los Angeles runs $1,800 to $4,200 depending on size, series, and what we find when the old door comes out. You get a written price before we start, and the work is covered by our 365-Day Done Right Promise.

How PGT Products Fail – and How We Fix Them

PGT builds a solid door, but no patio door survives a decade of Los Angeles sun and sliding without some attention. Here’s what we see most often on PGT doors in LA homes, by series where it matters:

• PGT 5500/7700 Series sliders: roller wear from patio grit. These are PGT’s mid-to-upper range aluminum and vinyl sliders, and they’re common in Los Angeles hillside homes and Valley ranches. The factory rollers are fine when clean, but LA’s fine dust and patio sand grind them down fast. The symptom is a door that lifts and drops as you slide it, or a metallic scrape. We replace the rollers with a matched set and adjust the track height so the door glides without putting load on the frame corners.
• PGT WinGuard sliders: seal compression loss, not glass failure. WinGuard is PGT’s impact-rated line, and Los Angeles homeowners in wind-exposed areas like the Palisades or the canyons often have it. The failure mode people assume is glass breakage, but the reality is the compression seals flatten over time and the door loses its airtight fit. You’ll feel drafts at the meeting stile. We replace the pile weatherstripping and re-shim the frame so the door meets the seal squarely, which restores the energy rating rather than forcing you to buy new glass.
• PGT SpectraGuard and Eze-Breeze: frame flex on wide openings. These lighter lines are built for screened porches and sunrooms, but on wide patio openings they flex. A homeowner will call us because the door binds at the top corner or won’t latch. The real cause is rarely the door; it’s the rough opening settling or the header sagging. We re-shim the frame to true, fix the reveal, and the door latches cleanly again. If the lintel is sagging, we say so and quote that separately, because patching the door won’t fix a structural issue.
• PGT 400 Series: slider track corrosion near the coast. Closer to the water, we see salt air corrode the aluminum track on older PGT 400 series sliders. The door drags, grinds, and eventually stops. The fix is a track replacement and a corrosion-resistant coating on the new one, plus a recommendation to keep the track clear of standing water. This is a case where an OEM track is worth the cost; aftermarket tracks on older PGT frames rarely seat correctly.
• PGT Classics: latch misalignment after years of slamming. The Classic series is everywhere in Los Angeles, from Mid-City to the Valley. The strike plate loosens, the keeper wears, and one day the door won’t stay locked. That’s a simple fix but it’s also a safety issue: a patio door that won’t latch is an open invitation. We drill and re-seat the strike, replace the keeper, and adjust the rollers so the door meets the frame without force.

Our PGT Patio Door Installation Process

Every PGT patio door install in Los Angeles runs the same way, from the first call to the final walkthrough:

1. 1
   Call and diagnosis. You tell us what the door is doing. We ask about the symptoms, the age, and the series if you know it. We’ll schedule a site visit at a time that works for you.
2. 2
   On-site measurement and inspection. We measure the rough opening, check the floor for level, and look at the existing flashing and weather barrier. If the door can be repaired instead of replaced, we’ll tell you that first. We don’t sell a replacement when a roller set fixes the problem.
3. 3
   Written price. You get a line-item price on paper before any work starts. The price does not move at the door. If we find hidden damage once the door is out, we photograph it, explain it, and get your written approval before a single extra dollar is spent.
4. 4
   Parts decision. For PGT doors, we use OEM parts where it matters: tracks, locks, and rollers. For seal materials and fasteners, we use proven equivalents that meet or exceed the factory spec. We’ll show you what we’re using and why.
5. 5
   Installation. The old door comes out, the opening is prepped, the new door goes in. We seal the pan, flash the frame, and set the rollers and stops. There’s no caulk mess left on the sill and no shims sticking out of the trim.
6. 6
   Test and walkthrough. We open and close the door 20 times, lock it, unlock it, run water on the exterior, and show you the operation. Then we register the job in our system and put the Done Right Promise in your hand, in writing.
