Mr-Glass Custom & Geometric Windows in Davie: What to Know First
We provide independent Mr-Glass custom and geometric window service in Davie, with most measured surveys scheduled within two business days and installations completed once the custom unit arrives from the manufacturer, typically four to six weeks for non-impact geometric shapes and six to ten weeks for impact-rated custom configurations. Every job starts with a written price based on the measured survey you keep, and that price does not change once work begins. This page is for Davie homeowners who own or are considering Mr-Glass custom, arched, curved, or oversized geometric windows and need an installer who works with the product line regularly, not a generalist who treats every brand the same. Call (754) 254-8492 to schedule your free measured survey.
How Mr-Glass Products Fail - and How We Fix Them
- Seal failure in the MG-Impact Arch series. The curved glazing in this line creates uneven thermal stress across the IG unit, particularly on south and west exposures in Davie where afternoon sun hits the arc directly. We see delamination starting at the apex of the curve, not the sides. Our fix: we order the replacement IG through Mr-Glass’s OEM channel with upgraded warm-edge spacer specification, and we verify the new unit’s argon fill with a gas analyzer before installation.
- Frame distortion in oversized MG-Custom fixed units. Mr-Glass’s custom line allows spans up to 60 inches in some configurations, but the aluminum frame can rack if the rough opening wasn’t plumbed to within 1/8 inch during original construction. In Davie’s Pine Island Ridge neighborhood, we’ve found this on several 2016-2019 builds where the framer rushed the opening. We fix it by installing a subframe that squares the opening before the new unit goes in, rather than forcing the window to fit a crooked hole.
- Hardware binding in MG-Geometric casement units with irregular polygons. The multi-point locking system on pentagon and trapezoid configurations relies on a custom-length rod that Mr-Glass builds to each order. When the rod stretches from repeated thermal cycling, the sash won’t seat evenly against the weatherstrip. We replace with OEM-spec rod assemblies and lubricate with silicone grease rated for Florida humidity, not general-purpose spray that attracts grit.
- Water intrusion at the head of arched retrofit installations. Mr-Glass arched units in retrofit applications need a properly flashed curved head; the factory nailing fin is designed for new construction. We’ve seen three Davie homes in the last eighteen months where a previous installer relied on caulk alone at the arch crown. Our fix: we fabricate a custom curved drip cap in aluminum brake metal, integrated with the existing wall weather barrier, before the unit is set.
- Coastal corrosion on non-impact custom units within three miles of the coast. Mr-Glass offers standard anodized and powder-coated finishes on its custom line, but the standard anodizing is 15 microns, not the 25-micron marine grade some Davie properties near the C-14 canal system need. We identify this during survey and specify the appropriate finish upgrade or recommend moving to the MG-Impact line with its heavier extrusion wall and enhanced coating.
Our Mr-Glass Custom & Geometric Windows Process

- 1
Measured survey. Sonia Raman or a background-checked, uniformed technician arrives with license number visible, measures every opening to 1/16 inch, and notes rough-opening condition, wall thickness, and interior trim constraints. You keep the survey document.
- 2
Written scope and price. We specify the exact Mr-Glass series, glazing package, and any custom fabrication required. The quote is the survey document with pricing added; Haven Clause 1 means these are the same paper.
- 3
Parts decision. For repairs, we source OEM Mr-Glass components when available and warranted. When lead times exceed eight weeks or the part is obsolete, we specify quality aftermarket alternatives with equivalent performance ratings and document the substitution in writing.
- 4
Installation. Our crew arrives on the scheduled date, removes the existing unit, preps the opening, sets the new Mr-Glass window with proper shimming and fastening pattern per the manufacturer’s engineering letter, and integrates flashing with the wall system.
- 5
Testing and documentation. We operate every moving part, check sash alignment with feeler gauges, verify lock engagement, and photograph the completed installation from interior and exterior angles. The photo record uploads to your file within 24 hours.
- 6
365-Day Done Right Promise activation. The Haven Standard warranty document is signed and dated before we leave. If anything is not done right, we make it right, no renegotiation.

AfterWhat Mr-Glass Custom & Geometric Windows Costs in Davie
These are the price ranges we have written on Mr-Glass custom and geometric jobs in Davie over the past twenty-four months. Your exact figure comes after the measured survey.
| Scenario | Typical Range |
|---|---|
| Standard geometric shape replacement (trapezoid, pentagon, circle-top) in retrofit | $1,400 - $2,800 per opening |
| Arched or curved fixed unit, new construction or full-frame replacement | $2,200 - $4,500 per opening |
| Oversized custom fixed unit (48″-60″ span), impact-rated | $3,800 - $6,200 per opening |
| IG unit seal failure replacement in existing geometric sash | $680 - $1,150 per unit |
| Hardware repair/replacement in MG-Geometric casement | $340 - $620 per sash |
| Custom curved drip cap fabrication and installation | $280 - $450 per opening |
What moves the price: impact rating versus non-impact, glass package (low-E, laminated, or both), finish specification, access difficulty (second story, interior trim protection), and whether the rough opening needs reframing. We do not charge separately for the measured survey or the photo documentation. Call (754) 254-8492 for your written estimate, estimates are free.
Why Davie Homeowners Call Sightline Windows & Doors Davie for Mr-Glass Work

We are independently owned and operated under the Haven Standard, not a franchise or a brand affiliate. Since 2012, we have installed and serviced more than 18,000 openings, and a growing share of that work in Davie involves Mr-Glass custom configurations that other installers decline because they lack the measurement confidence or the supplier relationship.
Our technicians carry license numbers, not just business cards. The 365-Day Done Right Promise is stamped on every job, not offered as a courtesy after a complaint. If Mr-Glass lead times stretch or a series discontinues, we can cross-specify from PGT, CGI, CWS, or ES Windows with equivalent performance data, because we maintain current specifications on all eight manufacturer lines we carry.
Sonia Raman measures twice before ordering anything. “Measure it right the first time. Everything else follows from that.” The written price you receive before work starts is the price on the final invoice. No change orders, no surprises.
FAQs
No, as an independent Mr-Glass service provider, our installation practices follow manufacturer specifications and Florida building code, which preserves warranty coverage on the product itself. The factory warranty covers defects in materials and manufacturing; our 365-Day Done Right Promise covers installation workmanship. We document both in writing before we leave your property. Call (754) 254-8492 if you have a specific warranty concern.
Non-impact custom shapes typically ship in four to six weeks from order confirmation; impact-rated custom configurations run six to ten weeks due to additional engineering review and testing documentation. These are manufacturer lead times, not ours. We do not mark up rush shipping, and we will tell you if a comparable PGT or CGI custom unit can meet your performance requirements with a shorter lead time. Call (754) 254-8492 to review options.
We repair when the frame is square and the glazing channel is intact. Seal failures, hardware binding, and weatherstrip deterioration are all repairable. Full replacement becomes necessary when the frame has corroded, the sash is out of square beyond shimming correction, or the energy performance you need requires a different glazing package than the original unit was built with. We make this determination during the measured survey and tell you directly which path costs less over ten years. Call (754) 254-8492 for a free assessment.
We stock common hardware components for the MG-Geometric and MG-Impact lines at our Davie facility: lock rods, hinges, and weatherstrip profiles for the most frequent configurations. Custom IG units, specialty shapes, and finish-matched extrusions ship from Mr-Glass. We verify parts availability before we quote so you are not surprised by a backorder after work is scheduled. Call (754) 254-8492 to check availability for your specific unit.
You receive four documents: the measured survey you already have, the final invoice matching the quoted price, the Haven Standard 365-Day Done Right Promise with the job-specific details filled in, and access to the dated photo record showing before, during, and after conditions. These are standard on every job, not an upgrade. Call (754) 254-8492 to schedule your installation.
