Mr-Glass Custom & Geometric Windows in Lighthouse Point: What to Know First
We provide independent Mr-Glass custom and geometric window service in Lighthouse Point, with most measured surveys scheduled within 48 hours and written quotes delivered before any deposit is taken. Custom and geometric Mr-Glass units in this market typically run $1,800 to $4,500 per opening depending on shape complexity, impact rating, and whether the original frame can be retained. This page is for homeowners who already own Mr-Glass products and need arched, curved, oversized, or otherwise non-rectangular window work done correctly the first time.
Call (754) 600-8907 to schedule your measured survey. We will hand you the written price before a tool is lifted.
How Mr-Glass Products Fail - and How We Fix Them
- MG-Impact series radius tops delaminate at the apex. The curved laminated glass in Mr-Glass’s impact-rated geometric units sees concentrated thermal stress where the radius tightens, especially on south and west elevations in Lighthouse Point. We see this most often on canal-front homes near the Lighthouse Point Marina where reflected water amplifies heat loading. Our fix: remove the sash, assess whether the lamination has begun to spider or the interlayer has slipped, then source a replacement radius top from Mr-Glass or, when lead times stretch, a matched laminated build from our verified aftermarket supplier. We document the original sightline measurement and the replacement in the photo record.
- MG-Architectural fixed geometric units lose seal integrity at mitered corners. The silicone backbedding in older MG-Architectural hexagons and octagons hardens unevenly in South Florida’s UV exposure, creating capillary paths for moisture. The symptom homeowners notice first is a clean, dry fog that clears by afternoon then returns. We do not inject “defogging” solution; we pull the unit, verify the spacer system, and replace with a warm-edge spacer build that matches the original sightline.
- Oversized MG-Impact Plus units sag in the head track. Mr-Glass’s heavier impact laminates in spans over 60 inches can stress the original aluminum header if the reinforcement was underspecified for the specific load path. We measure deflection with a straightedge and dial indicator, then specify either a reinforced replacement frame or a split-unit redesign that preserves the opening’s visual intent without the structural risk.
- MG-Geometric casement hardware strips at the operator gearbox. The worm-drive operators in shaped casements from the 2016-2019 production run used a pot-metal casting that fatigues under the additional torque of irregular sash weights. We stock the upgraded stainless gearbox assembly and replace the entire operator mechanism rather than patching with OEM-equivalent pot metal.
- Custom-color anodized frames chalk and fade unevenly. Mr-Glass’s coastal anodize specification on pre-2020 custom orders was 15 microns, which is adequate for inland Broward but marginal for salt-air exposure within a half-mile of the Intracoastal. We match the remaining frame color with a 25-micron replacement or, when the customer prefers, transition to a powder-coat rebuild with a documented salt-spray rating.
Our Mr-Glass Custom & Geometric Windows Process

- 1
Measured survey. Sonia Raman or a verified crew member arrives with a printed license number, measures every sightline and radius point with a digital caliper and story pole, and hands the customer the marked drawing to keep.
- 2
Diagnosis and parts decision. We identify the Mr-Glass series, production year, and failure mode. If Mr-Glass OEM lead time exceeds three weeks and the opening is weather-critical, we present a quality aftermarket option with matched performance specs and let the customer decide.
- 3
Written scope and price. The measured survey becomes the quote document. No line item is added after signature. Haven Clause 1: have it in writing.
- 4
Installation by verified crew. Background-checked, uniformed technicians arrive on the scheduled date. The customer receives a photo record of the opening before, during, and after.
- 5
Operational test and documentation. Every moving sash is cycled. Every fixed unit is pressure-checked for seal integrity. The customer keeps the final photo record and the 365-Day Done Right Promise document.
- 6
Cleanup and closeout. We do not leave until the opening is secure and the work area is clean. The invoice matches the written quote exactly.

Why Lighthouse Point Homeowners Call Sightline Windows & Doors Lighthouse Point for Mr-Glass Work

We are independently owned and operated under the Haven Standard, not a franchise, and we have handled Mr-Glass products since adding the line to our eight verified manufacturers in 2018. Sonia Raman and her crew know the difference between MG-Impact and MG-Architectural frame profiles by sight, which matters when you are trying to match a 2017 installation on a Lighthouse Point canal home and the original paperwork is long gone.
Our 365-Day Done Right Promise is stamped on every job, not offered as a courtesy. If the radius top we installed does not seat clean in the frame, we return and correct it. The photo record from every visit is yours to keep. And if Mr-Glass lead times do not work for your schedule, we can cross-reference your performance requirements against PGT, CGI, CWS, or ES Windows lines from our verified inventory.
Live phone coverage is available 24/7. The person who answers can schedule your survey and will know what “MG-Geometric casement with stripped gearbox” means.
FAQs
No. As an independent Mr-Glass service provider, we use OEM or matched-specification parts and document every step; manufacturer warranties on the glass unit itself remain intact, though any remaining installation warranty from the original contractor does not transfer to us. We cover our work under the 365-Day Done Right Promise. Call (754) 600-8907 to review your specific warranty status.
Mr-Glass OEM custom geometric glass typically ships in 4 to 6 weeks from order confirmation; radius tops and oversized laminates occasionally stretch to 8 weeks in peak season. We keep standard MG-Impact and MG-Geometric hardware in regional stock for same-week repair jobs. If your opening is weather-critical, we will present a quality aftermarket glass build with matched performance specs and a shorter lead time. Call (754) 600-8907 to check current availability.
Repair is possible when the frame is structurally sound and the failure is isolated to glass seal, hardware, or sash balance. Full replacement is necessary when the frame has deflected, the thermal break has failed, or the original geometry was mismeasured and the unit never operated correctly. We determine this during the measured survey and tell you directly which path costs less over the unit’s remaining life. Call (754) 600-8907 to schedule the survey.
That pattern indicates a failing edge seal, not interior moisture. Overnight temperature drop creates negative pressure inside the insulated glass unit; morning sun warms the air and drives residual moisture outward through the compromised seal, so the fog clears by afternoon. The seal will worsen. We replace the glass unit with a warm-edge spacer build that matches the original sightline. Call (754) 600-8907 for a measured survey and written quote.
Yes, when the replacement involves impact-rated products, structural modification, or changes to the opening dimensions. Lighthouse Point Building Department requires permits for impact window installations and verifies Florida Product Approval numbers during inspection. We pull the permit, schedule the inspection, and pass it before final invoice. The permit cost is listed in your written quote. Call (754) 600-8907 to confirm whether your specific job requires permitting.
