New windows and doors improve comfort, cut energy bills and add long-term value to your home. Sightline Windows & Doors Lauderdale Lakes pairs proven product lines with our own installing crews for lasting performance - and a price we put in writing.
1. Choose your installer
The unit is half the job - the install is the other half. Our own background-checked crews measure, set, seal and insulate every opening, and they know the lines we quote inside and out because they install them every week.
2. Select the right products
Compare styles, materials and glass packages side by side until the fit is right for your rooms, your budget and your goals. The product-line comparison below is the place to start.
3. Prepare your home for install
Before install day we walk you through a short checklist - furniture pulled back, treatments down, a clear path to each opening - so install day is watch-it-happen, not scramble.

Therma-Tru Window Replacement: The Lauderdale Lakes Owner’s Guide
We stock and install Therma-Tru-compatible window replacements in Lauderdale Lakes with typical installed prices running $340 to $780 per opening depending on series, glazing spec, and whether the frame needs re-flashing. Most standard sash and frame replacements we carry on the truck can be surveyed and started same week. Homeowners usually discover the failure when a window that once sealed tight now whistles during a summer storm, or when condensation appears between panes that used to read clear.
The telltale sign in Lauderdale Lakes is often the north-facing units failing first - they take the brunt of our driving rains without the drying benefit of direct sun. By the time water stains the drywall below, the seal has been compromised for months.
Which Therma-Tru Models This Applies To
Therma-Tru window systems span several series, and the replacement part you need depends on which generation is installed. Look for the etched marking in the glass corner or the sticker on the frame edge - the series code (typically starting with TTW or a four-digit SKU prefix) tells us whether you’re working with a builder-grade vinyl frame, an aluminum-clad wood unit, or one of their impact-rated lines.
We’ve replaced Therma-Tru sashes in the Oriole Gardens area where the original 2016-2019 vinyl double-hungs had sagging interlocks, and we’ve re-glazed their aluminum impact units along State Road 7 where the weep channels clogged with salt residue. The compatibility gotcha: Therma-Tru changed their sash-to-frame interlock geometry in 2018, so a 2017 sash won’t seat correctly in a 2019 frame even if the rough opening measures identical. We verify this with the serial number before ordering, not after.
OEM Therma-Tru parts ship from their distribution center in Ohio with a four-week lead time. We stock quality aftermarket equivalents manufactured to the same extrusion tolerances and glazing specs, with the same DP rating and warranty terms. The aftermarket route saves most Lauderdale Lakes customers $80-$140 per opening and cuts wait time from weeks to days.
Before
AfterSigns Your Therma-Tru Window Replacement Is Failing
- Visible moisture or fog between glass panes. The insulating glass unit (IGU) seal has failed, and the desiccant inside the spacer bar is saturated. In Lauderdale Lakes humidity, this accelerates once it starts - we’ve measured relative humidity above 85% behind failed seals during August surveys.
- Frame sag or sash that won’t stay open. The balance system has lost tension, or the vinyl jamb liner has deformed from heat cycling. South Florida’s UV exposure softens vinyl jambs faster than northern climates; we see this in west-facing units after six to eight years.
- Air infiltration around the sash perimeter. The weatherstrip has compressed or the sash interlock no longer mates flush. On Therma-Tru double-hungs, the bulb seal at the meeting rail is the first point of failure - it takes the abrasion every time the sash moves.
- Cracked or delaminated exterior cladding. Aluminum cladding separates from the wood substrate when water gets behind it, usually at mitered corners. This is structural; the frame is rotting underneath even if the interior looks sound.
- Hardware operation stiff or grinding. The sash lock or tilt-latch mechanism has corroded, or the keeper has shifted due to frame racking. On impact-rated units, the multi-point lock system adds complexity - a single failed pin can stress the entire mechanism.
Replacement Cost & What’s Included
| Scope | Price Range (Installed) |
|---|---|
| Standard sash replacement, vinyl double-hung | $340 - $520 |
| Impact-rated sash with laminated glass | $580 - $780 |
| Full frame replacement, standard opening | $720 - $1,100 |
| Full frame replacement, impact-rated | $1,200 - $1,680 |
| Re-flashing and exterior seal correction | $180 - $340 |
What drives the range: the glass package (single-pane IGU vs. impact-rated laminated), whether the existing frame is square and salvageable, and the exterior finish work required. Every quote we write in Lauderdale Lakes includes the measured survey you keep, the written scope with line-item pricing, and the photo record we deliver at completion. The price on the page is the price on the invoice - Haven Clause 1. Our 365-Day Done Right Promise covers the installation and the product; if the seal fails or the operation isn’t smooth, we return and correct it.

DIY or Call Us?
There’s a short list of checks any owner can make safely. Verify the window is fully closed and locked - an unlocked sash can read as a leak. Run your hand around the frame perimeter on a windy day to locate the draft source. Check the weep holes at the sill; if they’re clogged with debris or paint, clear them with a thin wire.
Where DIY goes wrong: removing a sash from a Therma-Tru impact-rated frame without supporting the weight properly can torque the jamb and void the warranty. Reglazing a failed IGU requires a clean-room environment; dust trapped between panes during assembly is permanent. And any frame replacement involving the nailing fin or flashing integration with your exterior wall is waterproofing work, not carpentry - we’ve re-done three Lauderdale Lakes jobs this year where the homeowner’s caulk line looked tight but channelled water behind the sheathing.
If the measurement isn’t written down, it doesn’t exist. Call (754) 240-8381 and we’ll survey the opening, write the price, and schedule the work.
FAQs
In South Florida’s climate, a properly installed vinyl or aluminum-clad replacement should perform 15 to 20 years for standard units, 12 to 15 for impact-rated lines under continuous UV and salt-air exposure. The IGU seal is typically the first component to age out; we’ve seen premature failure at eight years on west-facing elevations with no overhang. Call (754) 240-8381 for an exact quote on your specific opening - estimates are free.
Sometimes. A failed balance, weatherstrip, or lock mechanism can be component-replaced if the frame and IGU are sound. But a fogged IGU or rotted frame substrate requires full sash or frame replacement - there’s no field repair that restores the original thermal or structural performance. We evaluate this during the measured survey and tell you which path costs less over the unit’s remaining life. Call (754) 240-8381 for a free second opinion on any written estimate.
A standard sash replacement in an existing square frame takes two to three hours per opening. A full frame replacement with exterior trim and flashing integration runs four to six hours. We don’t quote in round numbers - the written scope specifies labor hours by task, and the crew documents start and finish times in the photo record. Call (754) 240-8381 to schedule your measured survey.
We stock the most common Therma-Tru-compatible sash assemblies, balance systems, and hardware for the series we see most frequently in Lauderdale Lakes. Specialty impact-rated glass or custom geometric shapes order in with a ten-day lead. We verify series and size before dispatch so the technician arrives with the correct part, not a return trip. Call (754) 240-8381 to confirm availability for your model.
