PGT Home Additions & ADU: The Fort Worth Owner’s Guide
If you own a PGT product and you’re planning a home addition or ADU in Fort Worth, the part you’re likely dealing with isn’t a failed spring or a cracked seal. It’s a PGT window or door that’s already in place and needs to be integrated, replaced, or re-flashed as part of a larger project. Home additions and ADU construction in Fort Worth typically runs $45,000 to $130,000, and when PGT products are involved, the window and door integration is where projects either go smoothly or get expensive.
Most homeowners call us because they’re adding a bedroom suite or building a backyard ADU, and the PGT windows or sliding doors they spec’d aren’t matching the rough openings on site. Or they have existing PGT impact windows from a 2015 install and the new addition needs to match them exactly. The PGT part of the job is rarely the headline, but it’s the part that creates schedule delays when it’s wrong. We’ve sorted enough PGT compatibility issues across Fort Worth that we know which questions to ask before the first wall goes up.
Key takeaways:
- Home additions in Fort Worth: $45,000 – $130,000. ADU construction: $90,000 – $220,000.
- PGT window and door integration is a specialty within the project. Getting it wrong means re-framing, which costs thousands.
- We’re an independent Fort Worth contractor. We install and integrate PGT products, but we’re not affiliated with PGT.
- Luca Romano still walks every project himself before quoting. No surprises at the door.
Which PGT Models This Applies To
PGT makes several window and door lines, and the compatibility question changes depending on what you have. The PGT WinGuard line is the big one in Texas: aluminum impact windows built for hurricane zones, and they’re common in Fort Worth homes where owners wanted hail and wind protection. PGT’s 5500 series and 7700 series are also out there, along with PGT sliding glass doors in the 500 and 700 series. Each line has different frame depths, different rough opening requirements, and different mullion options.
Here’s the gotcha most people miss: PGT WinGuard windows have a deeper frame profile than standard builder-grade windows. If you’re building an addition and the windows are ordered before the framing is finalized, you’ll end up with rough openings that are too shallow or too narrow. We’ve seen this happen twice in the Mistletoe Heights area alone in the last year. When you’re matching new PGT products to existing ones on the same wall, you need the exact series number, not just “PGT impact windows.” The label on the inside of the frame or the spacer bar between the glass panes will have the series and size code.
For the OEM-vs-aftermarket decision: with PGT, we almost always recommend OEM. PGT’s glass packs are tuned to their frames, and aftermarket glass from a generic supplier won’t carry the same wind load rating. For non-structural components like weatherstripping or rollers on PGT sliding doors, quality aftermarket parts from suppliers like Swisco work fine and save money. But when it comes to the glass, the sash, or the frame itself, OEM is the only option that keeps the Texas Department of Insurance windstorm certification intact. That matters in Fort Worth, especially if your insurance company is checking.

Signs Your PGT Home Additions & ADU Is Failing
- Condensation between the panes on existing PGT windows. The seal on the insulated glass unit has failed, and no amount of wiping fixes it. In Fort Worth’s summer heat, seal failure accelerates; we see it by year 12 – 15 on many PGT units, sometimes earlier on west-facing walls. For an addition, this means you’re either matching a window that’s already failing or replacing it as part of the build.
- Sliding PGT doors that drag or stick. The rollers are worn and the track is likely holding debris from Fort Worth’s spring winds. This is a fixable part, but if the door is older than a decade, you’re often better off replacing the whole panel rather than chasing roller replacements every year. When that door is part of an addition or ADU, the decision should be made before framing starts.
- Water staining around PGT window or door openings in the existing structure. The flashing or the sealant has compromised. This is the number one reason an addition budget blows up: you open a wall to tie in the new roofline and find water damage behind the old PGT unit. We always budget for this contingency on Fort Worth additions, and we show you the line item.
- Hairline cracks in PGT frame corners or mullion joints. Aluminum frames can stress-crack over time, especially after major storms. If you hear wind whistling through a closed PGT window near the Cultural District on a gusty day, that’s a sign the frame has moved. It won’t get better, and a cracked frame can’t be safely reused in a new addition.
- The PGT units don’t match the addition’s energy code requirements. Fort Worth now enforces IECC 2018 or newer on new construction. If your existing PGT windows were installed before 2015, they may not meet current U-factor and SHGC requirements for the addition. This is a compliance issue, not a preference. We check this on every walkthrough.
Replacement Cost & What’s Included
A home addition in Fort Worth runs $45,000 to $130,000 depending on square footage, complexity, and finish level. PGT window and door integration within that project typically falls between $8,000 and $25,000 depending on the number of units and whether you’re matching existing impact glass or starting fresh. A standalone ADU is a bigger number: $90,000 to $220,000, with PGT products usually accounting for $10,000 to $30,000 of that total when impact-rated windows and a sliding door are spec’d.
| Scope | Fort Worth Price Range |
|---|---|
| Home Addition (full project) | $45,000 – $130,000 |
| ADU Construction (full project) | $90,000 – $220,000 |
| Garage Conversion (full project) | $30,000 – $80,000 |
| PGT Window/Door Integration (within addition or ADU) | $8,000 – $30,000 |
| PGT Sliding Door Replacement (single unit) | $3,000 – $8,500 |
What drives the range: the number of PGT units, whether existing units are being matched or all-new, the framing corrections needed at rough openings, and whether the existing openings show water damage that must be repaired first. Every quote from Sawyer Remodel Fort Worth includes a written price before work starts, with parts and labor broken out separately so you know exactly what you’re paying for.

Here’s the honest split. You can absolutely verify the series numbers on your existing PGT units yourself. Open the window, look for the label, take a photo. You can also measure the rough opening width and height, which helps us quote accurately before we ever visit. Those two things save real time and money.
What you shouldn’t do is attempt to remove an existing PGT impact window or frame a new opening around it as a DIY project. Impact windows weigh 80 to 140 pounds for smaller sizes, and larger units need a two-person lift with suction cups. Drop a PGT impact window and you’re out $1,200 to $3,000 for a replacement, plus you’ve created a security opening in your house. Framing load-bearing walls around existing windows during a Fort Worth addition is structural work that needs an engineer’s stamp in most permit jurisdictions. If this is the part of the project you’re considering tackling yourself, skip it. Call us at (682) 841-6652 and we’ll come do a proper walkthrough. Estimates are free.
FAQs
PGT impact windows typically last 15 to 25 years in Fort Worth’s climate, with the insulated glass seal often failing around year 12 to 15, especially on west and south-facing walls. The frames themselves can last longer if the flashing was installed correctly and the weep holes stay clear. Our additions and ADU projects account for existing PGT units that are mid-life, and we replace failing units during the build rather than building around them. Call (682) 841-6652 and we’ll assess what you have.
Yes, but it depends on the failure. Hardware like rollers, locks, and weatherstripping is replaceable. A failed glass seal means replacing the insulated glass unit, not the whole frame, which runs $400 to $1,800 per unit depending on size and whether it’s impact-rated. A cracked aluminum frame corner cannot be reliably repaired, and we’ll tell you that plainly. For any PGT window or door problem in Fort Worth, we’ll give you the repair-versus-replace math before you commit.
For a typical Fort Worth addition with 8 to 14 PGT window and door units, the installation is scheduled across 2 to 4 working days once the framing and rough openings are finalized. That time includes setting, flashing, and interior trim where applicable. We coordinate the PGT install so the addition never sits open overnight, and the schedule is in your written quote before work starts.
We stock common PGT hardware: rollers for 500 and 700 series sliding doors, weatherstripping, locks, and sealant matched to PGT’s aluminum frame finish. Full window and door units are ordered per job from PGT’s Texas distribution network, typically 2 to 4 weeks for standard sizes and longer for custom or impact-rated configurations. If you need a specific PGT part for your Fort Worth home, call (682) 841-6652 and we’ll tell you the exact availability and price for the unit.
