Mr-Glass Custom & Geometric Windows in Three Lakes: What to Know First

We install and service Mr-Glass custom and geometric windows as an independent provider in Three Lakes, with most measured surveys scheduled within 48 hours and written quotes delivered before any work begins. Typical custom geometric installations run $1,800 to $4,500 depending on shape complexity and whether the opening requires impact-rated glazing. This page is for Three Lakes homeowners who already own Mr-Glass products and need arched, curved, or oversized custom units installed, replaced, or repaired with documentation they can keep. Call (786) 808-5792 to schedule your measured survey.

How Mr-Glass Products Fail - and How We Fix Them

• MG-Impact Elite series: seal failure in arched tops. The thermal break in the Elite’s curved frame extrusion can separate at the apex under repeated heat cycling. Three Lakes afternoon sun loads, especially on west-facing openings backing the Killian Corridor, accelerate this. We measure the sightline distortion, specify OEM replacement sashes when available, and document the glazing spec so the new unit matches the existing field.
• MG-Architectural line: corner joint separation in geometric assemblies. The mitered corners on triangular and trapezoidal units rely on a two-part structural adhesive that degrades faster in high-humidity microclimates. We’ve found this on three homes near the canal edges in Three Lakes where the dew point lingers. We disassemble, clean the joint channels to bare aluminum, and re-bond with specified structural sealant rather than surface-caulking the symptom.
• MG-Oversized fixed units: sagging at the horizontal mullion. Spans over 72 inches without intermediate support will creep over time, especially where the original installer undersized the reinforcing. We specify steel or composite reinforcement inserts per the engineering tables, not guesswork, and we photograph the deflection before and after.
• MG-Custom curved glass: delamination in laminated impact-rated lites. The interlayer can fog at the edges when the edge deletion is insufficient for the exposure. We check the existing edge seal against Miami-Dade NOA requirements and source replacement lites with corrected edge specifications when the original spec was marginal.
• MG-Hybrid venting units: hardware misalignment in radius-top casements. The curved track geometry changes as the frame settles, particularly in older Three Lakes construction with block walls that move seasonally. We re-square the frame, shim to plumb, and reset the hardware to the corrected sightline rather than forcing the sash to a bent track.

Our Mr-Glass Custom & Geometric Windows Process

1. 1
   Measured survey. Sonia Raman or a verified crew member arrives uniformed with license number visible, records rough opening dimensions to 1/16 inch, notes plumb and square deviations, and photographs existing conditions. You keep the survey document.
2. 2
   Written scope and price. We specify Mr-Glass OEM parts where the series is active, or quality aftermarket equivalents where OEM is discontinued, with the source named on the quote. The price on this document is the price on the invoice - Haven Clause 1.
3. 3
   Fabrication coordination. For custom geometric units, we verify the shop drawings against your field measurements before release to production. Lead times vary by complexity; we state the range in writing.
4. 4
   Installation with evidence. Crew arrives on schedule, installs per manufacturer specification, and photographs completed work including sealant joints, fastener patterns, and operational clearances.
5. 5
   Final test and documentation. We operate every moving part, check the sightline alignment, and deliver the photo record with the 365-Day Done Right Promise stamped on the completion document.
6. 6
   Cleanup and review. We remove debris, verify the work area, and leave the written warranty and maintenance guidance with you.

What Mr-Glass Custom & Geometric Windows Costs in Three Lakes

What moves the price: shape complexity, impact rating requirement, whether the original frame is reusable, and whether the opening needs structural reinforcement. We do not estimate over the phone - the measured survey determines the actual scope. Call (786) 808-5792 for your free estimate.

Why Three Lakes Homeowners Call Sightline Windows & Doors Three Lakes 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 the line entered the South Florida market. Our crew carries PGT, CGI, CWS, and ES Windows specifications as well, so when a Mr-Glass series is discontinued or the lead time doesn’t match your schedule, we can specify an equivalent performance unit from another verified line without starting your research over.

Every job gets the 365-Day Done Right Promise, the documented photo record, and the written price before any tool is lifted. Sonia Raman trains the crew to read a rough opening once and specify correctly - no return visits for remeasurement, no change orders because something “didn’t fit.” Measure once, quote it straight, install it right - nothing else belongs on the invoice.
