Therma-Tru Custom & Geometric Windows in Hobe Sound: What to Know First
As an independent Therma-Tru service provider in Hobe Sound, we measure, specify, and install custom and geometric windows from Therma-Tru’s decorative and architectural lines, including arched, curved, and oversized configurations. Most Therma-Tru custom window projects in Hobe Sound run $1,800-$4,500 installed, with shaped and impact-rated units at the higher end, and we put that range in writing before any work starts. Turnaround from measured survey to installation typically spans 3-5 weeks for standard custom geometries, longer for marine-grade impact laminates in salt-air zones like the waterfront near Peck Lake.
This page is for Hobe Sound homeowners who already own Therma-Tru windows and need replacement, upgrade, or new custom openings matched to existing Therma-Tru profiles, or who are comparing Therma-Tru decorative options against impact-rated alternatives from our other lines. Call (772) 362-5967 to schedule your free measured survey. The number we write down is the number on the invoice.
How Therma-Tru Products Fail - and How We Fix Them

- Decorative arched top sash seal degradation in Classic-Craft and Fiber-Classic series. The curved geometry concentrates thermal expansion stress at the springline joint, and Hobe Sound’s UV index accelerates the butyl sealant’s hardening. We see this most in west-facing units near Jonathan Dickinson State Park where afternoon exposure is relentless. We pull the sash, remove the degraded sealant mechanically, and re-bed with a neutral-cure silicone specified for curved substrates, not the flat-gasket method some crews use on rectangular units.
- Impact-lite geometric lite pattern delamination in Therma-Tru’s impact-rated custom shapes. The polygonal cuts for diamond, hex, and gothic lites create stress risers in the laminated interlayer that standard rectangular windows don’t experience. After Hurricane Nicole’s trailing winds in 2022, we documented three Hobe Sound homes where the lite pattern had begun fogging at the points. We replace with OEM-specified laminated glass from Therma-Tru’s approved fabricator list, or if lead times stretch past six weeks, we qualify an aftermarket laminate with matching interlayer thickness and document the substitution in your Haven Standard file.
- Fiberglass skin chalking on white and cream custom geometries. Therma-Tru’s Fiber-Classic fiberglass resists rot, but the gel coat on shaped units with complex profiles erodes faster than flat stiles because water pools in the cove details during Hobe Sound’s summer deluges. We don’t paint over it. We abrade to sound substrate, apply a catalyzed urethane repair coat, and finish with a UV-stable topcoat rated for 2,000 hours QUV, matching the original color by spectrophotometer, not eye.
- Operating geometric window hardware misalignment in Sentry and Traditions series. The curved top rail changes the geometry of the sash-to-frame relationship, so the standard balance shoe position calculated for rectangular units throws the lock points off by 3-8 millimeters. We’ve inherited jobs in Hobe Sound where previous installers shimmed the lock instead of relocating the balance. We recalculate the moment arm for the actual sash profile, relocate the balance shoe to the corrected position, and test through ten full cycles before we sign off.
- Condensation between panes in oversized custom Therma-Tru units. The spacer system in Therma-Tru’s larger geometric shapes, particularly those exceeding 60 united inches, uses a stainless steel box spacer that conducts cold more aggressively than warm-edge systems. In Hobe Sound’s humid shoulder seasons, the perimeter condensation this causes is often misdiagnosed as seal failure. We verify with a dew-point calculation against the actual U-factor and SHGC of the installed unit. If the spacer is the culprit and the glass is otherwise sound, we recommend a warm-edge retrofit or full sash replacement with a thermally improved spacer, depending on the age of the unit and remaining warranty term.
Before
AfterOur Therma-Tru Custom & Geometric Windows Process
- 1
Measured survey you keep. Sonia Raman or a verified crew member arrives with a printed license number, measures the rough opening twice, and records sightline dimensions, frame squareness, and wall plumb. You get a copy before we leave.
- 2
Diagnosis and specification. We identify the Therma-Tru series, manufacturing date code, and existing glazing specification. For custom geometries, we verify whether the original was a standard catalog shape or a true custom fabrication, which determines whether we order from Therma-Tru’s current catalog or initiate a custom shop drawing.
- 3
Parts decision with documentation. We quote OEM Therma-Tru components first. If lead times or discontinuation push us to aftermarket, we specify the substitute by manufacturer and part number, note any warranty implications, and require your initials on that line before ordering.
- 4
Installation under Haven Standard. Verified crews arrive uniformed and identified. We protect floors, remove the existing unit without disturbing surrounding trim where possible, install to the measured survey, shim to plumb, and seal with backer rod and sealant specified for the joint depth and Hobe Sound’s exposure.
- 5
Testing and photo record. We operate the unit through its full range, check lock engagement with a feeler gauge where appropriate, and photograph the installed condition, the sealant bead, and the label. These photos go to your Haven Standard file and your email within 24 hours.
- 6
Written warranty and 365-Day Done Right Promise. You receive the Haven Standard warranty document, the photo record access link, and our direct line. If anything’s not right, we make it right. Measure it right the first time, and the door closes the way it’s supposed to - every time after that.

FAQs

No. As an independent Therma-Tru service provider, we use OEM-specified parts and documented installation practices that preserve the manufacturer’s original warranty terms. We note any aftermarket substitution on your Haven Standard file and require your acknowledgment before proceeding. Call (772) 362-5967 if you have questions about your specific warranty period.
Standard catalog geometries typically ship in 2-3 weeks. True custom fabrications from Therma-Tru’s architectural shop can run 5-8 weeks, and impact-rated custom laminates sometimes extend to 10 weeks in peak season. We quote the current lead time in writing at measurement and will flag any aftermarket option that could shorten the wait without compromising performance. Call (772) 362-5967 for current availability.
Often, yes. We archive the profile dimensions and sightline measurements from your unit, then cross-reference against Therma-Tru’s current catalog and our aftermarket sources. For geometric shapes, we may need to fabricate a custom wood or composite template to verify the radius or springline angle. If a match isn’t possible, we specify the closest current equivalent with a documented comparison of sightline, frame depth, and performance values. Call (772) 362-5967 for a free second opinion on your replacement options.
Replace the insulated glass unit if the spacer has failed and the unit is under ten years old, repair the seal if the fogging is surface condensation caused by a degraded butyl bed. We determine which with a dew-point calculation and a borescope inspection of the spacer edge. Replacement IGUs run $890-$1,400 for most Hobe Sound geometries; seal repair is less, but we won’t recommend it if the spacer is compromised. Call (772) 362-5967 and we’ll diagnose it on the measured survey.
Yes, for any installation that alters the rough opening or changes the egress configuration. Martin County requires permits for window replacements that modify the structural opening or impact the home’s wind-borne debris protection rating. We pull the permit, schedule the inspection, and pass it before we finalize your Haven Standard file. The permit cost is listed as a line item in your written quote, not buried in overhead. Call (772) 362-5967 to confirm whether your specific project requires permitting.
