AfterTherma-Tru Custom & Geometric Windows in West Park: What to Know First
We install and service Therma-Tru custom and geometric windows in West Park as an independent Therma-Tru service provider, with most measured surveys scheduled within two business days and written quotes delivered before any work begins. A typical Therma-Tru geometric window replacement in West Park runs from $1,800 for a standard arched unit to $4,500 for oversized or impact-rated custom shapes, and we do not start until you have that number in writing. This page is for West Park homeowners who already own Therma-Tru products and need custom shapes, arched tops, or geometric replacements that match existing sightlines. Call (786) 685-4706 to schedule your measured survey.
How Therma-Tru Products Fail - and How We Fix Them
- Classic-Craft arched sashes with seal degradation in south-facing exposures. West Park’s combination of high UV and seasonal humidity attacks the dual-seal perimeter on arched Classic-Craft units faster than rectangular sashes. We see this most often in homes near Sunview Park where the original install left minimal expansion clearance. Our fix: remove the sash, document the rough opening dimensions, and reinstall with OEM-spec compression seals plus a 3/16-inch expansion gap that the factory detail sometimes omits in retrofit applications.
- Smooth-Star geometric windows with corner joint separation on radius tops. The mitered corners on Smooth-Star half-round and quarter-round units carry stress differently than square cuts, and the fiberglass skin can delaminate from the frame core at the radius transition after seven to ten years. We pressure-test the corner integrity, inject structural epoxy where the bond has failed, and replace the glazing bead rather than selling a full sash replacement when the frame is still square.
- Impact-rated custom shapes with laminated glass spidering from frame flex. Therma-Tru’s impact-rated geometric units use heavier laminated glass that transmits more load to the frame during pressure cycling. In West Park, where afternoon thunderstorms create rapid barometric shifts, we’ve found that units installed without proper shimming develop stress cracks at the narrowest point of the arch. We measure frame deflection under load and add supplemental shimming at the springline before reglazing.
- Oval and circle-top units with weep blockage from insect debris. The reduced slope on Therma-Tru oval windows collects organic matter faster than standard rectangles, and the weep channels are often undersized for West Park’s heavy pollen seasons. We clear the channels with compressed air and install screened weep covers that the original spec does not include, then document the modification in your job record.
- Direct Set custom shapes with failed adhesion between glass and stop. Therma-Tru Direct Set geometric units rely on structural silicone to retain the lite without a sash, and South Florida’s thermal cycling can fatigue that bond in twelve to fifteen years. We cut out the failed silicone, prep the stop with primer per Dow Corning specs, and re-bed with neutral-cure structural silicone rated for the unit’s design pressure. This is not a caulk gun job; the wrong silicone voids any remaining warranty coverage and the glass can fall.
Our Therma-Tru Custom & Geometric Windows Process
- 1
Measured survey and documentation. Sonia Raman or a verified crew member arrives in uniform with license number visible, measures the rough opening to 1/16 inch, photographs the existing unit, and records the Therma-Tru model stamp if present. You keep a copy of the survey; it becomes the basis for the written quote.
- 2
Diagnosis and parts decision. We determine whether the failure is frame, sash, seal, or glass, then source OEM Therma-Tru components or specify quality aftermarket equivalents where the OEM part is discontinued or the lead time exceeds what the opening can tolerate. We note the choice in writing with the price difference explained.
- 3
Written quote under Haven Clause 1. The quote matches the survey document exactly. No line item appears that was not measured. No allowance for “unforeseen conditions.” The price is the price.
- 4
Installation with evidence. The crew removes the failed unit, preps the opening, installs the replacement, and photographs each stage: rough opening before, shimming detail, fastener pattern, and finished sightline. These photos go into your job record.
- 5
Testing and sign-off. We operate the unit through full range, check seal compression with a feeler gauge where accessible, and verify weep function with a water test. You sign only after confirming the operation.
- 6
365-Day Done Right Promise activation. The Haven Standard warranty is stamped and dated. If the seal fails, the operation binds, or the sightline shifts, we return and make it right. The photo record proves what we did and when.

AfterWhat Therma-Tru Custom & Geometric Windows Costs in West Park
| Scenario | Typical Range | What Moves the Price |
|---|---|---|
| Standard arched replacement (Smooth-Star or Classic-Craft) | $1,800 - $2,800 | Radius size, impact rating, existing frame condition |
| Half-round or quarter-round geometric | $2,200 - $3,400 | Grid pattern, divided lite vs. single lite, finish color |
| Oversized custom shape (over 60 inches at springline) | $3,200 - $4,500 | Crane access, laminated glass thickness, DP rating required |
| Direct Set geometric re-glaze (glass retention failure) | $890 - $1,400 | Glass size, silicone type, scaffold or ladder work |
| Seal replacement and corner repair (sash serviceable) | $340 - $620 | Number of corners, seal type, disassembly complexity |
Impact-rated units add 35-50 percent to base cost due to laminated glass and reinforced frames. Homes in West Park built between 1960 and 1990 often need supplemental shimming or header reinforcement; we note this in the measured survey, not after demolition. Call (786) 685-4706 for your written estimate. Estimates are free, and we will review any competitor’s written quote at no charge under our Free Second Opinion policy.
Why West Park Homeowners Call Sightline Windows & Doors West Park for Therma-Tru Work
We have worked the residential streets near Sunview Park long enough to know which West Park homes still carry the original single-pane aluminum that preceded Therma-Tru retrofits, and what that means for rough opening condition when a geometric unit needs replacement. Our crews are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3, Verified Crews. We carry eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - so if a Therma-Tru lead time does not work for your opening, we can specify a geometric equivalent that matches the sightline and the performance requirement. The 365-Day Done Right Promise is written into every job, not offered as a courtesy. Measure it right, say what it costs, do the work. That is how we have handled 18,000-plus openings since 2012.
FAQs
Using an independent service provider does not automatically void a Therma-Tru warranty, but warranty coverage on custom and geometric units typically extends to original defects in material or workmanship, not seal failure from age or environmental exposure. We document every repair with photos and parts records so you have evidence if a warranty claim arises. Call (786) 685-4706 and we will review your warranty status before quoting.
Standard Therma-Tru geometric sashes and frames ship in two to four weeks; custom color or impact-rated configurations can run six to eight weeks. We maintain relationships with regional distributors in South Florida to expedite common Smooth-Star and Classic-Craft arch components, and we will tell you the real lead time before you commit, not after. Call (786) 685-4706 for current availability on your specific unit.
Repair makes sense when the frame is square, the glass is intact, and the failure is isolated to seals, hardware, or corner joints. Replacement is the better path when the frame has deflected, the laminated glass has spidered, or the unit is more than twenty years old and the parts are discontinued. We measure and photograph before recommending either. Call (786) 685-4706 for a free evaluation.
Yes. We cross-reference the original sightline dimensions against current Therma-Tru geometric offerings and, when necessary, specify equivalents from PGT, CGI, or CWS that maintain the same visible glass area and frame depth. The measured survey determines what will fit the existing rough opening without trim disruption. Call (786) 685-4706 to schedule the survey.
Standard Therma-Tru geometric replacements in West Park typically schedule within ten to fourteen days of quote approval, pending parts arrival. We do not promise same-day installation on planned window work; the Haven Standard requires that the measured survey and the written quote precede any start date. Call (786) 685-4706 to confirm current scheduling.
