Mr-Glass Custom & Geometric Windows in North Palm Beach: What to Know First
We install and replace Mr-Glass custom and geometric windows as an independent service provider in North Palm Beach, with most measured surveys scheduled within 48 hours of your call and written pricing delivered before any work begins. Custom shapes - arched tops, trapezoids, oversized fixed units - typically run 4-6 weeks from signed quote to installation, depending on glass tempering and laminate schedules. The price we write is the price you pay; Haven Clause 1 means the measured survey and the final invoice are the same document.
This page is for North Palm Beach homeowners who already own Mr-Glass products and need custom or geometric window work - new shaped openings, failed impact-rated geometric units, or retrofits in older homes where standard rectangles won’t fit. Call (561) 475-1246 to schedule your free measured survey.
How Mr-Glass Products Fail - and How We Fix Them
- MG-Impact Elite series - seal failure in arched and radius-top units. The curved aluminum extrusion on this line creates a thermal stress concentration at the springline where the arch meets the jamb. We’ve replaced dozens of these in North Palm Beach’s Lakeside Park neighborhood, where afternoon sun loads push the IG (insulated glass) edge seal past its design delta. We specify OEM warm-edge spacers with dual-seal silicone/polyisobutylene construction, not generic aftermarket, to restore the original 10-year seal warranty.
- MG-Architectural Fixed series - corner delamination in oversized trapezoid and pentagon shapes. These units ship with 9/16-inch laminated glass that carries more shear load at mitered frame corners than the corner keys were designed to manage, especially in openings over 60 united inches. We find the telltale white haze at the laminate edge before the glass cracks. Our fix: disassemble the frame, install reinforced corner brackets, and re-glaze with SentryGlas interlayer where the opening requires it.
- MG-Coastal Plus series - hardware fatigue in operable geometric casements. The concealed hinge system on triangle and trapezoid casements uses a 330-pound load-rated hinge that degrades faster in salt-air environments. North Palm Beach’s proximity to the Intracoastal means we see corrosion at 6-8 years, not the 12-year design spec. We replace with stainless steel hardware and add a weep-hole modification to evacuate standing water from the sill track.
- MG-Impact Elite series - frame racking in retrofitted concrete-block openings. The 3-inch frame depth assumes a plumb, square rough opening. In 1960s and 1970s concrete-block construction common east of US-1, we regularly measure out-of-square by 3/8 inch or more. Sonia Raman measures every opening herself on the first visit because a quarter-inch assumption costs two weeks and a re-order. We install custom sub-sills and head expanders rather than forcing the frame, which voids the impact rating.
- MG-Thermal Select series - Low-E coating degradation in south-facing geometric units. The soft-coat Low-E on this line is sensitive to edge exposure during installation. We’ve documented three cases in North Palm Beach where premature haze appeared within 18 months - traceable to installers who didn’t use setting blocks at the quarter points. Our protocol: setting blocks, edge clearance verification with feeler gauges, and photo documentation before the glazing bead seats.
Our Mr-Glass Custom & Geometric Windows Process

- 1
Measured survey. Sonia Raman arrives with a laser measure, level, and the printed Mr-Glass specification sheets for your series. You keep the survey document; it becomes the basis for the written quote.
- 2
Failure diagnosis or opening verification. For replacements, we identify the failure mode and photograph the evidence. For new custom shapes, we verify rough-opening tolerances against Mr-Glass’s fabrication limits - some radius combinations the factory simply won’t cut.
- 3
Parts specification. We quote OEM Mr-Glass components where the warranty requires it, and identify quality aftermarket alternatives where they exist. You see both options in writing with the price difference named.
- 4
Fabrication and delivery. Custom geometric units ship to our North Palm Beach warehouse, not directly to your driveway. We inspect for transit damage and verify glass markings against the order.
- 5
Installation and testing. Crew installs per Mr-Glass’s published installation guidelines, which we keep on tablet for reference. We operate every moving part, check every lock, and verify impact-rated installations with a documented sealant-bead inspection.
- 6
Photo record and warranty registration. You receive a link to dated installation photos and the completed warranty paperwork. The 365-Day Done Right Promise begins the same day.

What moves the price: glass type (annealed, tempered, or laminated impact-rated), shape complexity (true radius costs more than segmented), and whether the rough opening needs correction before the unit fits. We don’t estimate by phone; the measured survey is free, and the written quote is fixed. Call (561) 475-1246 to schedule yours.
Why North Palm Beach Homeowners Call Sightline Windows & Doors North Palm Beach for Mr-Glass Work

We’ve logged years of work in North Palm Beach, including retrofit projects in Lakeside Park where older concrete-block homes needed full rough-opening corrections before a single new unit could go in. That history matters when your geometric window has to fit a wall that wasn’t built for it.
The Haven Standard governs every job: written price before work starts, background-checked uniformed technicians with license numbers verified before arrival, and a documented photo record you can access. If it’s not done right, we make it right - Haven Clause 5, written, not verbal.
We also specify PGT, CGI, CWS, and ES Windows by performance tier and price range. If your opening is better served by another manufacturer, we’ll say so in writing. No one brand pays our bills; the right fit for the opening does.
If the opening isn’t right, the window isn’t right - that’s where we start.
FAQs
No - as an independent Mr-Glass service provider, we install per the manufacturer’s published guidelines and register warranty paperwork in your name. The warranty covers defects in materials and factory fabrication; our 365-Day Done Right Promise covers installation workmanship. Both documents travel together. Call (561) 475-1246 for specifics on your series.
Typically 4-6 weeks from signed quote, with true-radius shapes at the longer end. Tempered and laminated glass schedules vary by season; we quote a firm delivery window in writing, not an estimate. Rush options exist for some MG-Impact Elite lines at a premium we name upfront.
Sometimes. We cross-reference the original order code against current MG-Architectural Fixed and MG-Impact Elite profiles. When the exact extrusion is obsolete, we specify the closest current equivalent with a written note on sightline and frame-depth differences. We’ve sourced salvage units for 1980s-era MG products, though we document the no-warranty condition clearly.
We repair when the frame is sound and the failure is isolated: hardware, seal, or single-lite replacement. We recommend replacement when the frame is racked, the glass is delaminating at multiple corners, or the unit is pre-2010 and parts are no longer factory-supported. The written quote shows both paths where both exist.
The measured survey document with all opening dimensions, squareness readings, and frame condition notes. The written quote, itemized by labor, materials, and any opening correction. And a business card with Sonia Raman’s direct line. No charge for any of it. Call (561) 475-1246 to schedule.
