AfterPGT Door Installation: The Lighthouse Point Owner’s Guide
PGT door installation in Lighthouse Point typically runs $1,800-$4,200 for a standard single entry unit, depending on impact rating, frame material, and whether the opening needs reframing. We stock PGT-compatible hardware and carry the full PGT entry door and sliding door catalog on our trucks, and most Lighthouse Point installs are scheduled within a week of the measured survey. Homeowners usually discover a problem when the door sticks in summer humidity, the sweep gaps let water pool on the threshold after a storm, or the multipoint lock no longer throws cleanly - all signs the installation has shifted, settled, or was never quite square to begin with.
Which PGT Models This Applies To
PGT builds two primary door lines we install in Lighthouse Point: the PGT Entry Door series (fiberglass and steel slab options with impact-rated glass inserts) and the PGT Sliding Glass Door series (including the 770 and 780 pocket-sliding systems common on canal-front homes near the Lighthouse Point Marina). To identify your exact model, check the etched mark on the glass corner or the sticker rail on the frame edge - PGT stamps the series code, glass thickness, and impact certification there.
The OEM hardware - hinges, multipoint locks, roller carriages, and weatherstripping - is purpose-built to PGT’s track and frame dimensions. Aftermarket equivalents exist for some components (Truth Hardware makes compatible multipoint lock bodies, for instance), but the roller systems and impact-rated strike plates are proprietary. We stock both OEM and verified aftermarket on our trucks, and we’ll show you the part number and source before we quote. If your door was installed between 2015 and 2020, watch for the older PGT mortise lock body with the vertical throw bolt - that design was phased out in 2021, and the new body is not backward-compatible without a faceplate swap.
Signs Your PGT Door Installation Is Failing
- The door drags or binds at the top corner. This usually means the frame has racked out of square, common in Lighthouse Point’s older concrete-block homes where seasonal expansion shifts the header. The gap between the door edge and the jamb tells the story - we measure it at three points and record the variance on your survey.
- Water pools on the interior side after heavy rain. The PGT sill pan or end-dam seal has failed, or the sweep was never properly seated during the original install. Salt air near the marina accelerates the compression set in rubber sweeps; we see this on canal-front properties within four to six years.
- The multipoint lock handle turns but the bolts don’t engage. The lock body gears are stripped, or the frame has settled and the keepers no longer align. On PGT’s 2015-2020 mortise design, the zinc alloy gear housing cracks before the steel bolts wear - a known weak point we check during every service call.
- Daylight shows between the door and the frame when closed. The weatherstripping has compressed past recovery, or the door was never properly adjusted to the PGT-specified 1/8-inch perimeter gap. We see this on retrofits where a standard prehung was forced into a PGT opening.
- The sliding panel jumps the track or rolls rough. The PGT roller carriage bearings have corroded, or the track itself has dimpled from impact. The 770 series uses a tandem roller with a 1-1/4-inch wheel - not interchangeable with the 780’s 1-1/2-inch single wheel, a mismatch we find on about one in ten service calls.

AfterReplacement Cost & What’s Included
| Scope | Price Range in Lighthouse Point |
|---|---|
| Standard PGT entry door, installed (non-impact, fiberglass) | $1,800 - $2,800 |
| Impact-rated PGT entry door, installed | $2,600 - $4,200 |
| PGT sliding glass door, installed (standard size) | $3,200 - $5,500 |
| Hardware-only replacement (multipoint lock, rollers, sweep) | $340 - $780 |
| Reframe and install (rotted or out-of-square opening) | Add $600 - $1,400 |
What drives the range: impact-rated glass adds roughly $800-$1,200 per door, aluminum frames run 15% above fiberglass, and any reframing of the rough opening is priced by the linear foot and documented on your survey. Every quote we write in Lighthouse Point includes the measured survey you keep, the written scope with part numbers specified, and the photo record of the completed installation. The 365-Day Done Right Promise covers labor and hardware; PGT’s own glass and frame warranties run 10 years to lifetime depending on the series. No change orders, no surprises - Haven Clause 1 means the price on the page is the price on the invoice.
DIY or Call Us?
There’s a short list an owner can safely check: verify the door closes against the weatherstripping with even pressure top to bottom, look for visible screw loosening at the hinges or strike plate, and confirm the sill drain holes aren’t packed with debris. If you find a loose hinge screw, tighten it - but stop there.
What goes wrong fast: adjusting a PGT multipoint lock without the factory spacing gauge throws the keeper alignment off by millimeters and cracks the gear housing. Removing a sliding door panel to access rollers requires two people, proper lifting angle, and knowing which PGT series uses the top-hung versus bottom-roller design - get it wrong and the panel drops. And any work on an impact-rated door assembly that disturbs the glass-to-frame seal voids the Miami-Dade HVHZ certification. We’re background-checked, uniformed, and carry license numbers on every call - Haven Clause 3. For a door that actually seals and locks as specified, call (754) 600-8907 and we’ll schedule the measured survey.
FAQs
A properly installed PGT impact door in Lighthouse Point typically performs 15-20 years on the frame and glass, though hardware and weatherstripping need attention at 5-8 years due to salt-air exposure. The canal-front properties we service near the Lighthouse Point Marina often see faster sweep and hinge wear - we note this on your survey and price the maintenance cycle into our recommendation. Call (754) 600-8907 for an exact quote - estimates are free.
Often yes, if the frame is square and the glass is intact - hardware swaps, sill pan adjustments, and weatherstripping replacement are routine. We replace the door itself only when the frame has rotted, racked beyond adjustment, or the impact certification has been compromised. We document both options in writing before you decide. Call (754) 600-8907 for an exact quote - estimates are free.
A standard entry door replacement in Lighthouse Point takes one day; a sliding door or any reframing adds a second day. We arrive with the measured survey already completed and the specific PGT unit staged - no return trips for forgotten parts. Call (754) 600-8907 to schedule your survey and we’ll confirm the timeline in writing.
We stock PGT-compatible hardware - multipoint locks, roller carriages, sweeps, and weatherstripping - on our trucks, and we maintain inventory of the most common PGT entry and sliding door sizes at our warehouse. Less common sizes or custom glass patterns typically ship within 5-7 business days; we’ll tell you the exact lead time when we write your scope.
