PGT Home Additions & ADU Nationwide

PGT Home Additions & ADU: The Los Angeles Owner's Guide

PGT home additions and ADU construction in Los Angeles typically runs $53,100 – $153,400, depending on square footage, foundation work, and whether you're building up or out. We install PGT windows and doors as part of our addition and ADU builds, and we match replacement parts to existing PGT product lines when a unit fails or you're changing the footprint. Most Los Angeles homeowners discover a problem when a window or door stops sealing, a frame cracks, or an older PGT product no longer meets current Title 24 energy requirements.

We're an independent general contractor, not a PGT dealer or affiliate. That matters because we can source parts from PGT and also recommend quality aftermarket equivalents when lead times stretch or a product line has been discontinued.

Signs Your PGT Home Additions & ADU Is Failing

• Condensation between the glass panes. The insulated glass unit's seal has failed. In Los Angeles, the big temperature swings between coastal fog mornings and San Fernando Valley heat accelerate seal degradation. You can't repair the seal; you replace the IGU or the sash.
• Sash or panel doesn't sit square in the frame. This is usually a worn roller assembly or a bent hinge, but it can also mean the frame itself has shifted as the addition settled. We check the frame first before ordering parts, because a roller swap won't fix a structural issue.
• You feel a draft around the frame even when it's closed and locked. Weatherstripping has compressed or the locking points are out of alignment. Left alone, this becomes a bigger energy cost and a moisture path into the wall cavity.
• Crank operator on casement windows is slipping or grinding. The gear teeth inside the operator wear down over time. It's a quick repair with the right part, but only if the operator matches the frame's mounting pattern, which changed across PGT production years.
• Visible frame corrosion, especially on aluminum in coastal neighborhoods. Salt air off the Pacific eats painted aluminum faster than people expect. If you see bubbling paint or white oxidation around the weep holes, the structural integrity is declining and a patch isn't the right fix.

DIY or Call Us?

For most window and door hardware you can safely check the AAMA sticker, take a photo of the part, and note the frame dimensions. That photo and model information is often enough for us to give you a price before we come out. What gets owners into trouble is attempting to pull a sliding door panel alone. A large PGT slider weighs well over 200 pounds and once it leaves the track, it's easy to lose control of it. We've seen a dropped panel fling glass across a carport. For anything involving an impact-rated unit, the glass is laminated and heavy, and a mishandled replacement can crack a frame that was otherwise fine.

What we'd tell you to do instead: describe what you're seeing, text us a photo, and let us tell you whether we can fix it with a part we've got on the shelf or whether the sash needs to go to a glass shop. Either way, you'll know the number before anyone picks up a tool. That's how we operate. Give you a number first, then pick up the tools.

Can you match PGT parts if I don't know my product line?

Yes. We can identify the PGT model from the AAMA certification sticker on the frame edge, the etching in the glass corner, or from photos you send us. If the sticker is gone, we can often narrow it by measuring the frame profile and hardware type. Call (213) 277-6578 and we'll walk you through what to look for.

How long do PGT windows and doors last in Los Angeles?

PGT aluminum and vinyl products typically last 20 – 30 years with proper maintenance, though coastal exposure can shorten that to 15 – 20 years on the aluminum lines. Hardware like rollers and cranks is designed for 10 – 15 years of regular use. The insulated glass units, meaning the sealed double-pane assembly, usually hold for 15 – 20 years before seal failure shows up. Those are real-world numbers for this climate, not manufacturer marketing claims. A big factor in Los Angeles is UV exposure, which degrades the weatherstripping and exterior paint faster than in cooler climates. If you maintain your hardware, you extend the operational life before a full replacement becomes necessary. For an exact assessment of your specific windows or doors, call (213) 277-6578. We'll help you figure out whether you need a simple part replacement or a bigger solution.

Can a failing PGT part be repaired instead of replaced?

It depends on the part. Worn rollers, crank operators, weatherstripping, and lock mechanisms can usually be replaced with the sash left in place, which keeps the repair under $600 in most cases. A failed insulated glass unit cannot be safely repaired; the right fix is replacing the sash or the glass. A corroded aluminum frame is also a replacement situation because patching corroded metal doesn't restore structural strength. Before you assume the worst, have it looked at. We'll tell you honestly what can be repaired and what has to be replaced. Call (213) 277-6578 for a straight answer and a written price.

How long does a PGT part replacement take?

For hardware like a roller assembly or crank operator, the swap usually takes 30 – 90 minutes and we can often do it the same visit as the diagnosis. An insulated glass unit replacement usually takes a week to ten days because the sash has to go out for glass work. We quote every job in writing, so the schedule is part of the number you get up front. If you're asking about an entire addition or ADU project in Los Angeles, that timeline is defined by the design and permitting process, which typically runs several months before construction starts. For a specific timeline on your project, call (213) 277-6578 and we'll give you a realistic schedule.

Do you stock PGT parts locally?

We keep common PGT-compatible hardware on hand at our Los Angeles shop: rollers, crank operators, locks, handles, weatherstripping, and corner seals. For full sashes or custom-sized insulated glass units, we order to spec, and that lead time is typically one to two weeks depending on the product. We also carry parts compatible with KraftMaid, Cambria, and Silestone products for our kitchen and bath work. The size and age of your PGT product determines what we can pull off the shelf today and what we need to source. Call (213) 277-6578 and tell us what you're dealing with.

The Kingswell Way

Say the price before the work. Show up in the window we gave. Leave the place cleaner than we found it. Since 2004, every Kingswell location, including Penhallow Remodeling Los Angeles, has operated under that standard. A background-checked, uniformed technician should be the person you expect at the door, and a real person answers our phone 24/7. Those aren't extras. They're the baseline. Trevor Nash leads this location, and he's the first to tell you that a remodel or an addition only goes well when the person signing the work order understands exactly what they're paying for and what happens if we miss the mark.
