Mr-Glass Custom & Geometric Windows in West Palm Beach: What to Know First
We provide independent Mr-Glass service for custom and geometric windows in West Palm Beach, with measured surveys and written quotes that do not change once work begins. Most custom Mr-Glass installations we handle in the area, from arched casements to oversized fixed geometric units, move from survey to install in 4 to 8 weeks depending on glass specification and permit status. If the number isn’t on the page, it isn’t in the price.
This page is for homeowners in West Palm Beach who already own Mr-Glass products or are considering them for a custom opening, and want a technician who knows the difference between the MG-Impact series and the MG-Architectural line before arriving at the door. Call (561) 354-3861 to schedule your free measured survey. We will review any written estimate you already have at no charge.
How Mr-Glass Products Fail - and How We Fix Them
- MG-Impact series: Seal failure in radius-top and hexagonal units. The dual-seal warm-edge spacer system in early MG-Impact geometric configurations can degrade faster in West Palm Beach’s salt-air environment than in inland Florida markets. We see nitrogen loss and interior fogging most often on elevations facing the Intracoastal or within three blocks of the water. Our fix: we source replacement IGUs (insulated glass units) with upgraded stainless-steel spacer systems rated for marine-zone exposure, then document the argon fill level with a digital meter before installation.
- MG-Architectural line: Corner stress cracks in oversized fixed triangles and trapezoids. These units ship with minimal framing reinforcement because the design intent is maximum glass exposure. In West Palm Beach, thermal cycling between 95-degree afternoons and 72-degree conditioned interiors creates expansion differentials that concentrate at the mitered corners. We sister in concealed aluminum reinforcement brackets at the head and sill, then bed the unit in structural silicone rather than standard glazing tape to absorb movement.
- MG-Impact casement hardware: Hinge sag in custom-width units over 42 inches. Mr-Glass specifies standard three-point locking for widths up to 48 inches, but the hinge-side jamb on custom geometric casements often carries more weight than the design assumes, particularly with laminated impact glass. We replace the factory hinge set with heavy-duty stainless steel hinges from the same OEM supplier, then shim the frame plumb to within 1/16 inch to distribute load evenly.
- MG-Transom and sidelight assemblies: Water intrusion at the sill pan interface. Custom geometric transoms above Mr-Glass entry systems frequently arrive without integral sill pans, relying instead on field-applied sealant. In West Palm Beach’s driving rain patterns, especially on east-facing elevations, this fails within 18 to 36 months. We fabricate and install continuous aluminum sill pans with weeped drainage to the exterior, then tie them into the primary weather barrier with self-adhered flashing.
- MG-Architectural curved units: Laminate delamination in south-facing exposures. The curved tempered-laminated glass in MG-Architectural arched units can experience interlayer separation when the inner and outer lites heat at different rates. This is more common in West Palm Beach than in northern markets because of lower-angle winter sun reflecting off pools and patios onto the glass surface. We specify heat-strengthened rather than fully tempered outer lites for replacement, which reduces thermal shock susceptibility while maintaining impact compliance.
Our Mr-Glass Custom & Geometric Windows Process

- 1
Measured survey. Sonia Raman or a verified crew member arrives with a laser measure, level, and the Mr-Glass spec binder. We record rough opening dimensions, squareness, and plumb to 1/16 inch. You keep the survey document.
- 2
Diagnosis and parts decision. We identify the series, manufacturing date (encoded in the spacer bar), and failure mode. For discontinued MG-Impact configurations, we evaluate OEM-availability against marine-rated aftermarket IGUs and explain the trade-off in writing.
- 3
Written scope and price. The quote references the survey document by job number and lists every material, labor line, and permit cost. It also states what is not included. You sign once; the price does not change.
- 4
Fabrication and permit. For custom geometric units, we coordinate with the glass shop for templating and submit permit applications to the City of West Palm Beach or Palm Beach County as required. We handle the inspection scheduling.
- 5
Installation and testing. Crews arrive uniformed, with license numbers visible. We install per Mr-Glass structural specifications where applicable, then test operation, seal integrity, and drainage. We photograph every stage.
- 6
Documentation and follow-up. You receive the photo record, the completed warranty registration, and the 365-Day Done Right Promise in writing. We call at 90 days to confirm performance.

Prices move with glass specification (impact-rated versus non-impact), access difficulty (second-story geometric units over rooflines), and whether the original frame can be preserved. We do not quote until we measure. Call (561) 354-3861 for your free survey and written estimate.
Why West Palm Beach Homeowners Call Sightline Windows & Doors West Palm Beach for Mr-Glass Work

We are independently owned and operated under the Haven Standard, not a franchise or manufacturer affiliate. Every technician is background-checked, uniformed, and identified by license number before arrival, per Haven Clause 3. We have installed and serviced 18,000+ openings since 2012, and we carry eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - so we can specify what the opening requires rather than what we need to move from inventory.
The 365-Day Done Right Promise is stamped on every job, not offered as a courtesy. If a Mr-Glass unit we install does not perform as specified, we make it right. Our crews work regularly along Flagler Drive and throughout the surrounding West Palm Beach neighborhoods, and we understand the salt-air, high-velocity, and solar-loading conditions that geometric glass faces here.
FAQs
No - manufacturer warranties cover defects in materials and workmanship from the factory, not subsequent service. As an independent Mr-Glass service provider, we document every part we install and every procedure we follow, so if a factory defect is discovered, that evidence supports your claim. We also provide our own 365-Day Done Right Promise on all labor and non-OEM parts. Call (561) 354-3861 to review what coverage applies to your specific unit.
Sometimes, but not always. Mr-Glass discontinued several MG-Impact geometric profiles after 2019. We maintain relationships with the same OEM suppliers that fabricate for Mr-Glass, and we can often source dimensionally identical IGUs with upgraded spacer systems. When OEM parts are unavailable, we specify marine-rated aftermarket equivalents and explain the performance difference in writing before you approve the scope. Call (561) 354-3861 with your unit dimensions and manufacturing date.
Repair is viable when the frame is square, the hardware is functional, and the failure is isolated to the glass seal or a single component. Full replacement makes sense when the frame has twisted, the sash no longer seats properly, or the unit was incorrectly sized for the rough opening and has leaked repeatedly. We make this determination during the measured survey and tell you which path we would choose for our own property. Call (561) 354-3861 to schedule the survey - it is free.
Standard IGU replacements in existing geometric frames typically take 2 to 3 hours on site and can be completed in one visit if the glass is in stock. Full custom fabrications, including curved or oversized MG-Architectural units, require 4 to 8 weeks from approved quote to installation, with permit review adding 1 to 2 weeks in West Palm Beach. We do not promise speed we cannot verify; we promise a written schedule we keep. Call (561) 354-3861 for a timeline based on your specific opening.
Yes, for any replacement that alters the structural opening or involves impact-rated products. We submit to the City of West Palm Beach or Palm Beach County, coordinate inspections, and pass the certificate to you. The permit cost is listed in your written quote, not added later. Call (561) 354-3861 to confirm whether your project requires permitting.
