Therma-Tru Windows & Doors: The West Palm Beach Owner’s Guide
We stock and install Therma-Tru-compatible windows and doors throughout West Palm Beach, with most replacement parts running $400 – $1,800 installed depending on the component, and full entry-door replacements starting around $4,500. Most owners discover a failed part the way you probably did: a door that suddenly drags against the frame after a humid stretch, a window sash that won’t stay up, or weatherstripping that’s peeling away from the jamb like old tape. What’s failing is rarely the whole door or window. It’s one component that’s reached the end of its life in Florida’s salt air and heat. The good news is Therma-Tru parts are engineered to be replaced individually, and we keep the most common failures on the truck when we head out to Flamingo Park, El Cid, or anywhere else in West Palm Beach.
Which Therma-Tru Models This Applies To
Therma-Tru builds its entry doors around fiberglass slabs from the Classic-Craft, Fiber-Classic, and Smooth-Star lines, and its windows follow a standard size-and-jamb convention that makes parts matching far less guesswork than most people expect. The part you need almost always traces back to two things: the door or window’s manufacture label (a white sticker on the hinge edge of the door slab, or the top rail of the window sash) and one measurement. For door thresholds, it’s the width between jambs. For weatherstripping, it’s the kerf slot width, usually 3/16 inch. For window balances, it’s the length stamped on the old balance’s metal channel. If the label is long gone, a photo of the part and one measurement is usually enough for us to identify it before we arrive.
On OEM versus aftermarket: Therma-Tru’s own replacement parts are built to the exact tolerances of the original, and for things like adjustable sills, corner seals, and compression weatherstripping, we’d never substitute anything else. For window balances and door sweeps, there are quality aftermarket equivalents that match or exceed the originals, and we’ll tell you which is which so the price makes sense. Elmstead Remodeling West Palm Beach is an independent service provider, not affiliated with Therma-Tru, and we also keep parts in stock for KraftMaid cabinetry, Cambria and Silestone countertop hardware.

Signs Your Therma-Tru Windows & Doors Is Failing
- The door catches at the top of the frame or won’t latch without lifting the handle. This is usually hinge sag or a worn sill cap, both common in West Palm Beach’s humidity cycles that expand and contract the fiberglass and frame at slightly different rates.
- You can see daylight or feel air moving around the door’s edges. Compression weatherstripping loses its rebound after 7 – 10 years in Florida heat, and the corner seals at the bottom of the jambs are almost always the first to go.
- The window sash slides down on its own or is hard to lift. The spring balance inside the side channel has lost tension. On Therma-Tru windows this is a sealed-unit balance, and it’s a 20-minute fix with the right part.
- Water pools on the interior sill after a heavy rain. The sill pan or the door sweep has failed. In West Palm Beach’s summer downpours, a worn sweep lets wind-driven rain ride right up and over the threshold.
- Condensation appears between the glass panes of the window. The insulated glass unit has lost its argon fill and the seal is gone. This is a sash or glass-pack replacement, not a repairable seal.

AfterReplacement Cost & What’s Included
For a single Therma-Tru part replacement in West Palm Beach, most jobs land between $400 and $1,800 installed, with the part itself, the labor, the trip, and the disposal of the old component all in the written price. A weatherstrip refresh on one door runs $400 – $700. A new adjustable sill or threshold assembly is $600 – $1,200. A window balance replacement runs $500 – $900 per window. A full entry-door slab replacement starts at $4,500, and if you’re pairing it with a larger project, a full window replacement across the home typically ranges from $4,500 – $15,000. You’ll get the written price before any work starts, itemized by part and labor, and our 365-Day Done Right Promise covers the completed work. If it’s not done right, we make it right.
DIY or Call Us?
What you can safely do: take a photo of the failing part, read the label if it’s still attached, and take one measurement. That’s genuinely useful, and it helps us bring the right part on the first visit. What gets people into trouble is prying off old weatherstripping without the right extraction tool and gouging the kerf slot, or trying to force a sagging door level by over-tightening hinge screws into stripped-out wood. The screws spin, the holes wallow out, and a $600 repair becomes a jamb replacement. Door slabs are heavy, window balances are spring-loaded, and a slab off its hinges is a finger-crush risk. Call (728) 203-3270. We’ll match the part, put it in writing, and do exactly that.
FAQs
The door slab itself lasts 25 – 30 years or more; it’s the wear components around it, weatherstripping, sweeps, sill caps, and window balances, that fail every 7 – 10 years in Florida’s humidity and salt air. Most calls we make in West Palm Beach are for those parts, not for the door itself. Call (728) 203-3270 and we’ll tell you which category yours falls into.
Most failed components are replaceable, not repairable, and that’s actually good news because the replacement is often cheaper than a patched-together fix. Weatherstripping, sweeps, sills, and balances are all designed to be swapped individually. Call (728) 203-3270 for a straight answer on your specific part.
Most single-part replacements take under two hours from the time the crew sets down the drop cloths. A full door slab replacement is a half-day job. We’ll give you a firm start and end window in the written estimate before we begin.
We keep the most common Therma-Tru weatherstripping, sweeps, sill caps, and window balances on the truck for West Palm Beach service calls. Unusual sizes or finish-matched slab replacements may need a few days to order. Either way, the written price comes before the work starts, and the phones are answered by a live person 24/7.
