New windows and doors improve comfort, cut energy bills and add long-term value to your home. Sightline Windows & Doors Fort Lauderdale 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 Custom & Geometric Windows in Fort Lauderdale: What to Know First
We install and service Therma-Tru custom and geometric windows in Fort Lauderdale as an independent provider - not a factory-authorized dealer, which means we work with the units you already have and source parts based on what the opening actually needs. Most custom Therma-Tru geometric jobs in Broward County run three to five weeks from measured survey to installation, with written pricing locked at the survey stage. We don’t start work until you have that written price in hand; Haven Clause 1 means the quote and the final invoice are the same document.
This page is for Fort Lauderdale homeowners with Therma-Tru arched, curved, or oversized geometric windows that need replacement, re-glazing, or impact-rated upgrading. If you’re comparing options across brands, we also specify PGT, CGI, CWS, and ES Windows when the opening calls for it. Call (754) 666-7478 to schedule your free measured survey.
How Therma-Tru Products Fail - and How We Fix Them
- Classic-Craft arched top lights develop seal creep in the curved jamb. The radius puts constant tension on the insulated glass unit’s edge seal; in Fort Lauderdale’s salt-air environment, that tension accelerates argon loss and interior fogging. We measure the exact chord and rise, then order a replacement IG unit with a dual-seal warm-edge spacer rated for curved applications - not a flat unit forced into a curved frame.
- Smooth-Star geometric sidelites warp at the mullion joint. The fiberglass skin and composite frame expand at different rates under South Florida’s UV load, which opens a gap at the mated corner. We disassemble the mullion, check the structural insert for moisture intrusion from past hurricanes or driving rain, and rejoin with a back-rod and structural sealant specified for dissimilar materials.
- Therma-Tru impact-rated geometric units lose their NOA compliance after improper field modification. We’ve seen Fort Lauderdale homes where a previous installer notched a Miami-Dade-approved arched frame to fit a new header, voiding both the product and installation warranty. We pull the original Notice of Acceptance, verify the unit as specified, and if the frame is compromised, we quote a compliant replacement - never a patch.
- Oversized Therma-Tru custom rectangles sag in the header over 72-inch spans. The fiberglass pultrusion is strong but not immune to gravity; without proper reinforcement, the operating sash drags. We specify steel-reinforced Therma-Tru frames for spans over 60 inches, or we engineer a divided-lite solution that splits the visual opening while maintaining the sightline the architect intended.
- Geometric gaskets harden and crack at the southern exposure. Therma-Tru’s EPDM glazing gaskets have a 10-15 year service life in normal climates; Fort Lauderdale’s combination of UV, ozone, and salt cuts that roughly in half on unshaded elevations. We replace with marine-grade silicone gaskets where the original spec allows, and we document the elevation and exposure in your photo record for future reference.
Before
AfterOur Therma-Tru Custom & Geometric Windows Process
- 1
Measured survey you keep. Sonia Raman or a licensed technician records every dimension - chord, rise, jamb depth, rough opening squareness, and wall condition - on a document you receive before we leave. Two measurements, one order. “Measure it right the first time or measure it twice on someone else’s dime.”
- 2
Parts decision: OEM or verified equivalent. We check Therma-Tru lead times against your timeline. Factory arched sashes can run 8-10 weeks; some geometric IG units we can source from our ES Windows or CWS relationships with equivalent Miami-Dade ratings and faster turnaround. We explain the trade-off in writing.
- 3
Written scope and price. Haven Clause 1: the survey, the scope, and the price are a single document. You approve it or you don’t. No change orders on Therma-Tru jobs unless you change the spec.
- 4
Installation by verified crew. Haven Clause 3: background-checked, uniformed, license number provided before arrival. For geometric units, we send a two-person team - one to manage the unit, one to verify plumb and level continuously.
- 5
Test and document. Every Therma-Tru installation gets an operational test, a seal inspection with smoke pencil, and a photo record of the finished opening, the label, and the surrounding wall condition. You get the photos; we keep the backup.
- 6
365-Day Done Right Promise activates. If the sash binds, the seal fails, or the sightline reads crooked, we return and make it right. Written into the Haven Standard, not a verbal favor.
What Therma-Tru Custom & Geometric Windows Costs in Fort Lauderdale
| Scenario | Typical Range |
|---|---|
| Standard arched top light replacement (IG unit only, frame sound) | $890 - $1,450 |
| Geometric sidelite re-glazing with marine-grade gasket upgrade | $620 - $980 |
| Full Therma-Tru custom geometric unit, impact-rated, 48″-60″ chord | $2,400 - $3,800 |
| Oversized custom rectangle with steel reinforcement, 72″+ span | $3,200 - $5,100 |
| Mullion rebuild on failed Smooth-Star corner joint | $780 - $1,200 |
What moves the price: radius complexity (true half-circle vs. eyebrow), impact rating requirement, whether the original frame can be retained, and accessibility - second-story geometric units in Fort Lauderdale’s Coral Ridge or Las Olas Isles often require interior protection and specialized handling. We price this at the survey, not after we’ve started.

Why Fort Lauderdale Homeowners Call Sightline Windows & Doors Fort Lauderdale for Therma-Tru Work
We’ve installed and serviced more than 18,000 openings since 2012, and a measurable subset of those have been Therma-Tru custom and geometric units in Fort Lauderdale’s 2015-2023 construction wave. That repetition matters: we know the difference between a Classic-Craft and a Smooth-Star failure pattern before we remove the trim, and we know which Therma-Tru parts are on factory backorder before we promise you a date.
When Therma-Tru lead times don’t match your timeline, we specify from our other seven lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, or ViewLux - based on what the opening requires, not what we have in stock. Every technician is background-checked, uniformed, and identified by license number before arrival. Every job leaves a documented photo record. And every quote is the final invoice - Haven Clause 1, unchanged since 2012.
FAQs
No - provided we use OEM-specified parts and follow the published installation guidelines. As an independent Therma-Tru service provider, we are not affiliated with or authorized by Therma-Tru, but we document every step to preserve any remaining factory coverage. Call (754) 666-7478 and we’ll review your warranty status during the free estimate.
Factory arched and curved sashes typically run 6-10 weeks; standard geometric IG units are often 3-4 weeks. We maintain relationships with ES Windows and CWS that can cut that timeline for equivalent impact-rated units when the opening allows. We tell you the real lead time at the survey, not after you’ve signed.
About forty percent of the Therma-Tru geometric calls we see in Fort Lauderdale are repairable - re-glazing, gasket replacement, mullion rebuild. The other sixty percent involve frame compromise, failed impact seals, or discontinued profiles where replacement is the only code-compliant path. We diagnose before we quote; you get the honest assessment in writing.
Yes, for any impact-rated or structural modification. We handle the permit application, the inspection scheduling, and the final sign-off. The permit cost is in your written quote - Haven Clause 5, no surprises.
It doesn’t. Haven Clause 1 means the measured survey and the written quote are the same document. The only way the price changes is if you change the scope. We’ve held to this since 2012 across all 18,000+ openings. Call (754) 666-7478 for your free estimate - the price you get is the price you pay.
