PGT Impact Windows & Doors in Kendall: What to Know First
We provide independent PGT impact windows and doors service in Kendall, from single hung retrofits to full-frame horizontal roller replacements. Most PGT jobs we measure on Monday are in production by Thursday, with a written price delivered before any work starts - Haven Clause 1, no exceptions. As an independent PGT service provider, we are not affiliated with or authorized by PGT Industries; we source OEM and quality aftermarket parts based on what the opening actually needs, not what a distributor is pushing. If you own a PGT window or door in Kendall and need it fixed right, call (786) 321-3319 for a free estimate.
How PGT Products Fail - and How We Fix Them
- WinGuard single hung balance spring fatigue. The constant up-and-down in Kendall’s humid coastal air corrodes the balance shoe track faster than inland installs. We see this most in 2008-2016 vintages near the Dadeland area. We replace with stainless balance assemblies, not the standard zinc kit, and we document the frame squareness before the new hardware goes in.
- WinGuard horizontal roller wheel track grooving. The brass wheel on the aluminum sill plate cuts a groove over time, especially where patio doors see heavy traffic from pool decks tracking grit. On PGT’s 7700 series, this groove catches debris and locks the sash. We mill the sill flat, install a stainless cap track, and swap to polymer-tread wheels that don’t gall the aluminum.
- Laminated glass delamination at the edge. PGT’s impact-rated laminated units can breathe at the edge seal in South Florida’s wet-dry cycling. The symptom looks like a fog ring you can’t wipe off. We source replacement IGUs from the same laminator PGT uses, or from Cardinal or AGC depending on lead time, and we never re-use a compromised frame.
- Vinyl frame corner separation on early EcoView series. Heat buildup in west-facing Kendall townhomes - especially the blocks near SW 88th Street - can stress-weld the mechanical corners on pre-2015 vinyl frames. We pull the sash, re-square with a heated press, and mechanical-fasten the corner with aluminum reinforcement. Full-frame replacement only if the glazing pocket is out of tolerance.
- Multi-point lock actuator strip corrosion. The zinc-diecast actuator in PGT’s French and sliding door systems seizes when the grease washes out in driving rain. We see this on homes three miles from Biscayne Bay more than anywhere else. We replace with a stainless actuator where available, or treat the OEM part with a marine-grade dry lubricant and document the service interval.
Our PGT Impact Windows & Doors Process

- 1
Measured survey. We record every opening to the sixteenth: frame width at three points, plumb, level, and square. You keep the survey sheet. The quote is built from these numbers - not a guess, not a range.
- 2
Parts diagnosis. We identify the PGT series, manufacturing date range, and whether OEM parts are still in production or if a quality aftermarket equivalent outperforms the original. We explain the trade-off in writing.
- 3
Written price delivery. Haven Clause 1: the price you sign is the price on the final invoice. No change orders for conditions we should have seen at survey. Measure once, document it, then cut.
- 4
Verified crew arrival. Haven Clause 3: background-checked, uniformed technician, license number provided before arrival. The person on the dispatch sheet is the person at your door.
- 5
Installation and live test. Dry-fit before sealant. Impact-rated products get a post-installation operability test and a photo record of the sealant bead, the fastener pattern, and the closed-lock position.
- 6
Documentation and guarantee. You receive the photo record, the completed scope sheet, and the 365-Day Done Right Promise in writing. If it’s not right, we make it right.

Why Kendall Homeowners Call Sightline Windows & Doors Kendall for PGT Work

We’ve been measuring and setting frames in Kendall for years - most recently finishing a full impact-window retrofit on a block of townhomes near Dadeland Mall. Sonia Raman insists on a dry-fit before any sealant touches glass, a habit that has saved more than a few jobs from a costly redo. Our 365-Day Done Right Promise is written into the Haven Standard, not offered as a courtesy. If PGT parts are back-ordered, we draw from our verified lines - CGI, CWS, ES Windows, ECO Window Systems - specified by what the opening requires, not by what is in stock. Every job leaves a documented photo record. Every price is written before any work starts.
FAQs
No - PGT’s warranty covers manufacturing defects, not independent service. We document every part source and installation detail so any future warranty claim with PGT remains clean. If your windows are still under PGT’s original warranty, we flag potential claims before we touch the unit. Call (786) 321-3319 and we’ll review your warranty status at no charge.
Most single-component repairs - balance, wheel, lock actuator - are completed in two to four hours on site. Full-frame replacements need one to two days depending on the opening count and whether we hit a Miami-Dade building inspection window. We schedule around your availability, not ours. Call (786) 321-3319 to book a measurement.
Repair when the frame is square, the glazing pocket is intact, and the failure is in a replaceable component. Replace when the frame has corner separation beyond heated repair, the IGUs are delaminating across multiple units, or the original install was out of plumb and the sash is binding. We tell you which side of that line you’re on - in writing, before you spend anything. Call (786) 321-3319 for a free assessment.
We stock common wear parts - balances, wheels, weatherstrip, standard lock bodies - in our Kendall-area warehouse. Discontinued series parts or custom IGUs are ordered per job with a lead time we disclose in the written quote. We never charge a rush fee for parts we should have had on the shelf. Call (786) 321-3319 for availability on your specific series.
We offer a free second opinion on any written estimate. Bring us a competitor’s quote and we will review the scope, the parts specified, and the labor line items at no charge. If their price is lower for identical work, we’ll show you where the difference is - and if we can’t match it with the same quality, we’ll say so. Call (786) 321-3319 to schedule your review.
