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.

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 South Miami Heights: What to Know First
As an independent Therma-Tru service provider in South Miami Heights, we measure, order, and install custom and geometric Therma-Tru windows with written pricing locked before any work begins. Most Therma-Tru custom and geometric projects in this area run four to six weeks from measured survey to final installation, depending on whether the unit is a standard arched top or a true radius requiring laminated template approval. We do not quote over the phone; Haven Clause 1 requires the measurement and the price to be the same document. If you own a Therma-Tru product and need a custom or geometric window repaired or replaced in South Miami Heights, call (786) 481-0414 to schedule your measured survey.
How Therma-Tru Products Fail - and How We Fix Them
- Classic-Craft arched units develop seal creep at the springline. The thermal break in the pultruded fiberglass frame shifts slightly with each heat cycle in South Miami Heights, and after five to seven years the argon fill bleeds at the apex of the arch. We spot this with a deflectometer reading at the springline; if the gap exceeds 0.4 mm, we order a replacement sash with upgraded warm-edge spacer, not a field reglaze that voids the remaining warranty.
- Smooth-Star geometric shapes collect water in the lower jamb channel. The drain slots in the original extrusion are 3/16-inch and clog with the fine limestone dust that blows through South Miami Heights during dry season. We pull the sash, machine the weep slots to 1/4-inch, and install stainless weep covers so the channel drains before the sill rot starts.
- Fiber-Classic double-hungs with custom grilles show hairline cracks at the muntin joints. The SDL (simulated divided lite) bars are surface-applied and the South Florida UV load degrades the adhesive in thirty-six to forty-eight months. We do not caulk over this; we remove the failed bars, clean the glass surface to 600 grit, and apply new factory-matched SDLs with UV-stable adhesive rated for 2,000 hours QUV.
- Impact-rated custom shapes from the Therma-Tru Coastal series lose lamination clarity at the edges. The PVB interlayer in impact geometric units can delaminate if the frame expands beyond the glass bite, which happens in South Miami Heights when the east-facing units see morning sun followed by afternoon thunderstorm cooling. We measure the glass bite against the current AAMA 101 spec; if the frame is out of tolerance, we spec a replacement with deeper glazing pocket, not a re-glaze.
- Direct-Set geometric units settle out of square in stucco returns. The South Miami Heights building stock from the 1980s and 1990s used soft stucco with minimal lath; the Therma-Tru nailing fin compresses into this substrate and the unit rakes. We sister the fin with aluminum angle, shim to plumb, and document the final sightline measurement so the customer has a baseline for future inspection.
Before
AfterOur Therma-Tru Custom & Geometric Windows Process
- 1
Measured survey. Sonia Raman or a verified crew member arrives with a documented checklist. We record rough opening dimensions in three places, note the stucco condition, and photograph the existing unit’s label code. The customer keeps this survey.
- 2
Diagnostics and parts decision. We identify the Therma-Tru series, manufacturing date from the NFRC label, and whether the failure is frame, sash, seal, or glazing. OEM parts are spec’d when available; when Therma-Tru has discontinued a profile, we source quality aftermarket with matching thermal performance and document the substitution in writing.
- 3
Written scope and price. Haven Clause 1: the quote is the measured survey with line-item pricing. No change orders. The customer approves in writing before any order is placed.
- 4
Installation. Background-checked, uniformed technicians arrive with license numbers visible. We set the unit to the documented sightline, seal with backer rod and specified sealant, and photograph every stage.
- 5
Testing and documentation. We operate the unit through full travel, check drainage with a calibrated water stream, and deliver the photo record and written 365-Day Done Right Promise.
- 6
Cleanup and final invoice. The invoice matches the written quote to the cent. No surprises.
What Therma-Tru Custom & Geometric Windows Costs in South Miami Heights
| Scenario | Typical Range |
|---|---|
| Standard arched top replacement, Classic-Craft or Smooth-Star, up to 60″ x 84″ | $1,800 - $2,600 |
| True radius or eyebrow geometric, template-required, under 48″ x 48″ | $2,400 - $3,400 |
| Oversized custom geometric, impact-rated, with laminated template | $3,800 - $5,200 |
| SDL grille replacement on existing geometric unit | $340 - $580 |
| Seal failure reglaze (non-impact, standard shape) | $620 - $940 |
What moves the price: impact rating adds 35-45 percent; true radius requiring CAD template adds $280-$420; stucco repair after removal adds $400-$800 depending on finish match; second-story access in South Miami Heights’s older ranch-style homes with limited setback adds lift time. We do not estimate until we measure. Call (786) 481-0414 for your free measured survey and written price.
Why South Miami Heights Homeowners Call Sightline Windows & Doors South Miami Heights for Therma-Tru Work
We are independently owned and operated under the Haven Standard, not a franchise, and we have installed and serviced 18,000+ openings since 2012. Every one had a written price first and a photo record at completion. Our technicians are background-checked, uniformed, and identified by license number before they arrive at your South Miami Heights home. We carry eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - so if a Therma-Tru profile is discontinued or the lead time exceeds your need, we can specify a functionally equivalent unit from another line with comparable thermal numbers, also in writing. The 365-Day Done Right Promise is stamped on every job, not offered as a courtesy. Calls are answered by a live person, 24/7. Bring us any competitor’s written estimate and we will review it at no charge.
FAQs
No. As an independent Therma-Tru service provider, we use OEM or equivalent-spec parts and document every step; the manufacturer’s original warranty on the frame and glass remains intact, and our 365-Day Done Right Promise covers our installation labor separately. We have never had a warranty claim denied due to our workmanship documentation. Call (786) 481-0414 if you want us to review your warranty paperwork before we start.
Standard custom shapes from Therma-Tru’s current catalog ship in four to five weeks; true radius or discontinued profiles requiring template approval can run six to eight weeks. We do not quote delivery dates we cannot verify with the factory. If your opening is exposed, we can spec a temporary board-up or a standard rectangular interim unit from our PGT or CGI stock. Call (786) 481-0414 to discuss timing.
Yes, if the pattern is from a current or recently discontinued SDL catalog. We measure the bar width, shadow box depth, and clip spacing, then order factory-matched replacement. For obsolete patterns, we fabricate custom SDLs to the same sightline dimensions and document the substitution in your file. We do not approximate; the customer approves the sample before production. Call (786) 481-0414 to schedule a pattern match.
Replace if the frame is out of square more than 1/8 inch, if the impact lamination has started to delaminate, or if the unit is pre-2010 and the profile is discontinued. Repair if the failure is isolated to seal, hardware, or surface SDL. We make this recommendation in writing with a photo of the defect and a price for each option. No pressure either way. Call (786) 481-0414 for the assessment.
Yes, for any replacement that alters the rough opening or changes the egress capacity. Miami-Dade County requires permit and inspection for impact-rated installations; we pull the permit, schedule the inspection, and include the permit cost in the written quote. The customer receives the passed inspection card and the photo record together. Call (786) 481-0414 to confirm whether your specific job requires permitting.
Ready to get a written price on your Therma-Tru custom or geometric window project? Call (786) 481-0414 to schedule your free measured survey. We will bring the checklist, take the photos, and leave you with a document you can compare against any other quote.
