PGT Impact Windows & Doors in Lantana: What to Know First

We provide independent PGT impact windows & doors service in Lantana, with most diagnostic visits scheduled within 48 hours and repairs completed on a second visit once parts are confirmed. A written quote from our measured survey is the price on the invoice - Haven Clause 1, no exceptions. Typical PGT jobs in this zip code run from $340 for a single-hung sash replacement to $2,800 for a full-frame horizontal roller install, and we stock common PGT hardware for the 4100 and 5400 series to avoid the 10-14 day factory lead time.

This page is for Lantana homeowners who already own PGT impact windows or doors and need repair, replacement, or an honest second opinion on another contractor’s quote. If you’re comparing brands, we also specify and install CGI, CWS, ES Windows, and ECO Window Systems - but this page covers what we know about PGT from eighteen thousand openings of hands-on work.

How PGT Products Fail - and How We Fix Them

• WinGuard 4100 Single-Hung: balance shoe fracture from salt-air corrosion. The nylon balance shoes in the 4100 series absorb coastal salt through the weep channels faster than PGT’s inland testing predicted. We see this on Lantana beachfront homes east of Ocean Avenue, where the shoes crack after 6-8 years instead of the rated 15. Our fix: we replace with OEM PGT balance shoes but reroute the weep path and add a stainless steel drainage insert that PGT doesn’t ship standard. The sash travels smooth again, and the next replacement interval doubles.
• WinGuard 5400 Horizontal Roller: roller carriage seizure in the bottom track. The 5400’s tandem roller assembly binds when beach sand mixes with the factory grease and the aluminum track oxidizes. Homeowners notice the sash jumping or requiring two hands to slide. We don’t just swap rollers - we pull the sash, media-blast the track to bare aluminum, apply a dry PTFE lubricant that won’t attract grit, then install heavy-duty stainless tandem rollers. The difference is measurable: a 5400 we serviced last March on Hypoluxo Island now moves at 2.3 pounds of pull force, down from 14.
• WinGuard Architectural (AW) Series: corner key separation in the frame. The AW series uses a mechanical corner key with a set screw, not the welded corners of the vinyl lines. In Lantana’s thermal cycling - 90°F days, 72°F nights, eight months a year - the aluminum expands and contracts until the corner key loosens. You feel a draft, or you see daylight. We disassemble the frame, clean the old threadlocker, apply fresh anaerobic sealant, and torque to PGT’s 45 in-lb spec with a calibrated driver. We document the torque reading in your photo record.
• WinGuard Vinyl Double-Hung: interlock failure between meeting rails. The vinyl meeting rails on double-hung units can deform if the sash cords are adjusted unevenly, breaking the weatherstrip seal that gives the impact rating its integrity. This is invisible from inside - you only notice the wind noise during a northeaster. We check rail squareness with a digital caliper, replace the interlock gasket with PGT-spec EPDM, and rebalance both sashes to within 1/16 inch of travel height. The unit tests to design pressure after.
• WinGuard Door Multi-Point Lock: spindle wear in the MPL mechanism. PGT’s multi-point lock spindles are brass, and the mating gears in the MPL are zinc. In high-use doors - the ones facing west, taking afternoon sun and daily traffic - the brass outlasts the zinc by about 8 years. The latch points stop retracting in sequence, and you have to lift the handle hard to engage. We source the full PGT MPL assembly rather than piecemeal gears, because aftermarket gear sets don’t match the 5/16 inch spindle diameter exactly and will chew the new brass in two seasons.

Our PGT Impact Windows & Doors Process

1. 1
   Measured survey and symptom documentation. We arrive with a calibrated laser measure, a digital level, and a camera. Sonia Raman or a Haven Clause 3 verified crew member records the rough opening dimensions, the existing unit’s PGT series label (usually etched in the glass corner or on the frame edge), and the specific failure symptom. You keep this survey sheet.
2. 2
   Diagnostics with the sash or panel removed. For impact units, we don’t guess from the floor. We remove the sash or active panel to inspect the frame interior, the hardware pocket, and the glazing bead condition. This is where we find the secondary failures - the corroded screw we didn’t expect, the cracked glazing tape - that would turn a $400 repair into a ol,200 callback.
3. 3
   Parts decision: OEM PGT versus verified aftermarket. We quote OEM first, with PGT’s current lead time noted. For hardware that fails predictably - the 4100 balance shoes, the 5400 rollers - we stock quality aftermarket that matches the OEM spec and costs 30-40% less. We write both options on the quote, with the warranty implication for each. You choose before we order.
4. 4
   Repair or replacement execution. Our crew works from the written scope, not memory. Every fastener is torqued to spec, every seal is photographed before and after, and the unit is cycled 20 times minimum before we call it done.
5. 5
   Pressure test and photo record delivery. For impact repairs, we verify the sash locks and interlocks engage with a feeler gauge. We then upload the dated photo record to your customer portal, with the torque readings, the parts labels, and the final sightline measurement. The 365-Day Done Right Promise attaches to this document.
6. 6
   Cleanup and invoice match. The invoice line items match the quote line items, unit for unit. If we found something we didn’t expect and fixed it, it’s on the invoice with a zero charge and a note explaining why. Measure it right the first time. Everything after that is just paperwork.

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

We’ve logged work on homes from the Lantana beachfront corridor west to the Hypoluxo Island bridge - enough to know that PGT’s inland corrosion testing doesn’t match what salt air does to a 4100 balance shoe. Sonia Raman writes the U-factor and impact rating of every unit on the quote before the contract is signed, because numbers on the page outlast promises in the air.

The 365-Day Done Right Promise is stamped on every job, not offered as a courtesy. Our crews are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3. If your PGT unit is discontinued or the lead time extends past your need, we specify from our other seven lines: CGI for heavy-duty aluminum, CWS for value-engineered vinyl, ES Windows or ECO Window Systems for specific performance tiers. We don’t stock what we can’t document.

Calls are answered by a live person, 24/7. The person who answers can see your file, your photo record, and your warranty status.
