Plant Prefab Windows & Doors: The West Palm Beach Owner's Guide
Replacing or repairing windows and doors on a Plant Prefab home in West Palm Beach typically runs $4,500 to $15,000 installed, depending on how many openings you’re addressing and whether the frames are salvageable. We stock Plant Prefab-compatible window and door assemblies on our trucks and can usually have the first replacement unit in hand within two to three business days. Most owners discover the problem the same way: a window that won’t seal against summer humidity, or a door that swells shut after a hard afternoon rain off the Atlantic.
Plant Prefab builds with modular precision, which means the rough openings are tighter than what you’d find in a stick-built home. That’s good news for energy performance. It also means a generic big-box window will fight you during install. We measure to the eighth-inch before ordering anything.
Which Plant Prefab Models This Applies To
This page covers windows and doors across Plant Prefab’s current and recent production lines, including the LivingHome series and the Yves Béhar-designed units that have gone into developments around South Florida. The key is the rough opening, not the model name. Plant Prefab documents every module with a build sheet that lists window and door make, series, and dimensions. If you still have the owner’s packet from delivery, that sheet is the fastest way to match a part.
Here’s the compatibility gotcha most owners miss: Plant Prefab has used multiple window suppliers over the years depending on the project’s sustainability targets and the architect’s spec. You can’t assume every opening in your home takes the same manufacturer. We’ve seen LivingHomes with Marvin fiberglass on the street-facing elevation and a European tilt-turn line on the rear. Same house, two different frame depths. Before we quote anything, we pull the build sheet or measure the existing frame in place. That’s the only way to get the thermal break and flange profile right.
For OEM versus aftermarket: if the original manufacturer still makes the series, we’ll quote the OEM first. The thermal performance numbers will match what the home was designed around. If that series is discontinued, a quality aftermarket unit from a manufacturer like Therma-Tru (doors) or a documented equivalent (windows) is the next call. Either way, you get a written price before we touch the opening.

Signs Your Plant Prefab Windows & Doors Is Failing
- Condensation between the glass panes. That means the sealed unit has lost its argon or krypton fill and the desiccant inside the spacer is saturated. The insulating glass unit is done. You can’t dry it out, and the fix is a replacement IGU or full sash, not a caulk bead.
- Visible daylight around the door slab. The weatherstripping is compressed past recovery or the slab has shifted on its hinges. On a Plant Prefab door, check the reveal first; a fractional frame shift is common after the module settles, and it’s often corrected with a hinge adjustment rather than a new door.
- Window won’t stay open or operates like it’s grinding sand. The balance mechanism or the operator hardware has worn out. Salt air from the Intracoastal accelerates this on coastal West Palm Beach lots, and it’s the single most common hardware failure we field calls about.
- Draft or increased indoor humidity near the frame. The perimeter seal between the window flange and the module opening has failed. In Florida’s wet season, this shows up as peeling paint or soft drywall at the sill before you ever feel the draft.
- Discoloration or sagging at the sill. Water has been getting past the sill pan or the weep holes are blocked. On Plant Prefab units with recessed sills, clogged weeps are the first thing we check; it’s a five-minute fix if caught early, a frame replacement if ignored.

AfterReplacement Cost & What's Included
Here's the honest range for West Palm Beach, based on what we've quoted and installed on Plant Prefab homes in the area:
- Single window replacement (standard size, fiberglass or vinyl): $1,200 – $3,500 installed
- Full-home window package (8-12 openings, including removal and disposal): $4,500 – $15,000 installed
- Single exterior door replacement (Therma-Tru or equivalent, pre-hung): $2,500 – $6,000 installed
- Sliding glass door replacement (Plant Prefab-compatible frame depth): $3,500 – $8,000 installed
Every line item includes removal of the old unit, disposal, any substrate repair at the opening, the new unit, perimeter sealing, interior trim, and a signed written guarantee. The range comes down to three things: how many openings, what the existing frame depth requires, and whether we’re pulling permits. Window and door replacements in West Palm Beach that change the opening size will require a permit and an inspection. Same-size replacements generally won’t. We’ll tell you which applies to your job before the first crew rolls up.
The 365-Day Done Right Promise covers the finished work for a full year. If the window or door fails inside that window, we come back and correct it at no charge. That’s in writing, every time, under The Garrison Standard.

Some things are safe to check yourself. Confirm whether the weep holes at the sill are clear. Check the weatherstripping for compression. Look at the hinges for obvious sag. Those are diagnosis steps, and they cost you nothing.
Here’s where it goes wrong: pulling a window or door out of a Plant Prefab module thinking it’s a simple swap. The rough openings are machined tight. If you torque the frame or break the flange seal, you’ve turned a $1,500 window replacement into a $4,000 wall repair. The same goes for setting a pre-hung door without addressing the module’s settle pattern. The frame might look square, but the floor plate may have moved a quarter inch since delivery. If you’re not measuring from the module corner, you’re guessing.
We’d rather you call before prying anything loose. Curtis Lane will walk the openings with you, line by line, and give you a straight number. Call (728) 203-9809 to schedule a free estimate.
FAQs
A well-installed Plant Prefab window or door in South Florida will give you 20 to 30 years on the frame, with the insulating glass unit often needing replacement at the 10 to 15 year mark due to seal failure from heat and humidity cycling. Coastal properties with direct salt exposure tend toward the shorter end. We can quote either a full-unit replacement or an IGU-only swap, depending on what the frame looks like when we open it up. Call (728) 203-9809 for an exact assessment — estimates are free.
Yes, in about half the cases we see. If it’s a failed IGU, broken balance, or worn weatherstripping, we repair the assembly in place for $400 to $1,800 depending on the part and access. If the frame is rotted, racked, or the flange seal has let water into the module wall, replacement is the only honest fix. We’ll show you what we’re seeing before anyone starts work. Call (728) 203-9809 to have a technician take a look.
Most single-window replacements are done in one day. A full door replacement, including substrate repair and re-trimming, takes one to two days per opening. A full-home window package on a Plant Prefab typically runs three to five working days from first cut to final inspection, assuming the weather cooperates and the units arrive on schedule. Call (728) 203-9809 and we’ll give you a schedule in writing.
We stock common Plant Prefab-compatible hardware, weatherstripping, balances, and standard-sized door slabs on our trucks. Custom-size window units and full door assemblies are ordered to spec from manufacturers like Therma-Tru, with a two to three business day lead time in most West Palm Beach cases. If we don’t have your part, we’ll tell you on the first call before scheduling anything. Call (728) 203-9809 to confirm availability for your model.
