Mr-Glass Impact Windows & Doors in Boca Raton: What to Know First
We provide independent Mr-Glass impact windows and doors service in Boca Raton, with most repairs completed in one visit and full replacements typically surveyed, quoted, and installed within two to three weeks.

This page is for homeowners in Boca Raton who already have Mr-Glass impact-rated units and need honest diagnostics, warranty-safe repair practices, or a straight replacement quote without the runaround. Call (561) 200-8592 to schedule your free estimate.
How Mr-Glass Products Fail - and How We Fix Them
- Mr-Glass 100 Series single hung impact windows: sash drift and balance failure. The constant humidity cycling in Boca Raton - morning dew at 80 percent, afternoon sun baking the vinyl - fatigues the coil balance springs faster than inland Florida markets. We see this most in west Boca Raton homes near the Loxahatchee preserve where afternoon heat lingers. We replace with OEM-spec balances and lubricate the tilt latches with silicone compound, not petroleum grease that attracts grit.
- Mr-Glass 200 Series horizontal roller impact windows: hard roll and track deformation. The stainless steel rollers corrode at the axle pin when salt air penetrates the bearing seal, usually after four to six years in oceanfront Boca Raton properties. The symptom feels like the sash is fighting you. We pull the sash, measure track flatness with a straightedge, and replace with marine-grade rollers that have sealed ceramic bearings - aftermarket, but spec’d to the same 150-pound sash load rating.
- Mr-Glass impact sliding doors: water intrusion at the sill track end dams. The factory end-dam seal is a compression-fit vinyl piece that shrinks in our UV exposure. Water finds the gap, pools in the subfloor, and the first sign is a spongy interior transition. We remove the track, document the rough opening condition with photos you receive, and reseal with backer rod and neutral-cure silicone that flexes with thermal movement. If the sill pan is compromised, we say so and price the replacement - no hidden damage.
- Mr-Glass laminated impact glass: spider cracking from edge impact, not center strike. The interlayer holds, but moisture wicks through the edge seal and clouds the lite from the perimeter inward. This is almost always a full glass replacement, not a repair. We order the exact OEM glass package with the same .090 PVB interlayer thickness and matching Low-E coating so your U-factor and SHGC stay consistent with the adjacent units.
- Mr-Glass vinyl frame corner separation at the weld. Thermal expansion stress concentrates at the miter weld on dark-colored frames in direct sun. The gap is usually hairline at first, then grows. We assess whether the frame is still square and structurally sound; if yes, we disassemble, clean, and re-weld with a heat-profile joint that matches the factory spec. If the frame has twisted, we quote replacement - trying to force a square sash into a racked frame is how you get binding and premature seal failure.
Our Mr-Glass Impact Windows & Doors Process

- 1
Call and schedule. A live person answers, or you text us back. We ask for photos if the failure is visible, and we pull Mr-Glass shop drawings from our archive to prep for the visit.
- 2
Measured survey on arrival. Sonia Raman or a verified crew member arrives in uniform with license number visible. We measure rough opening width, height, and square - diagonals within 1/8 inch - and record frame color code, glass stamp, and hardware finish. You keep the survey sheet.
- 3
Diagnosis and parts decision. We determine if the fix needs OEM Mr-Glass parts, quality aftermarket equivalents, or full unit replacement. We explain the trade-off: OEM guarantees color match and warranty alignment; aftermarket saves time when Mr-Glass lead times stretch past eight weeks. You decide. We write the price.
- 4
Repair or replacement with evidence. Work proceeds per the written scope. We photo-document before, during, and after - frame condition, fastener placement, sealant bead, and final operation test. The photo record uploads to your job file by end of day.
- 5
Operation test and sign-off. Every moving part cycles twenty times. Impact-rated units get a visual seal inspection and a water spray test at the sill if we touched the glazing. You sign the completion form; we leave the written warranty and the final invoice - same number as the quote.
- 6
365-Day Done Right follow-up. We call at thirty days to check operation. If anything shifts in the first year, we return and make it right. That’s Haven Clause 5, written on every contract.

Why Boca Raton Homeowners Call Sightline Windows & Doors Boca Raton for Mr-Glass Work

We are not a Mr-Glass dealer. We are an independent Mr-Glass service provider with eighteen thousand openings of field experience since 2012, and we carry eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - so if your Mr-Glass unit is discontinued or the lead time doesn’t work, we can specify a performance-matched alternative with the same Miami-Dade NOA and publish the comparison in writing.
Our crews are background-checked, uniformed, and identified by license number before they knock. Every job leaves a documented photo record. The 365-Day Done Right Promise is stamped on the contract, not offered as a favor. And when Sonia Raman says she’ll recheck a measurement that already checked out, her crew knows to wait - because “measure it twice, write it down, then we can talk price” is how we avoid the shimming and caulk-covering that passes for craftsmanship elsewhere.
FAQs
No, if the repair uses OEM-spec parts and practices. We document every part number and procedure so warranty coverage remains intact. Using non-spec hardware or unqualified labor can void protection, which is why we record what we used and why. Call (561) 200-8592 if you need us to review your warranty terms before we start.
OEM Mr-Glass parts typically ship within two to four weeks; quality aftermarket equivalents we stock can often shorten repair turnaround to same-week. For full unit replacements, we confirm lead time in writing before you commit - no surprises. Call (561) 200-8592 to check current availability for your series.
Usually yes, within the current Mr-Glass color chart. Discontinued colors may require a full-frame replacement of the adjacent unit for visual consistency, which we will flag and price as an option - never as a pressure tactic. We bring color chips to the survey and compare in your actual light. Call (561) 200-8592 to schedule a match check.
Repair when the frame is square, the glass package is intact, and the failure is isolated to hardware or seal. Replace when the frame is racked, the glass is compromised, or the unit is pre-2010 and parts are obsolete. We give you both prices when both are viable and explain why one makes more sense for your opening. Call (561) 200-8592 for an honest assessment.
Yes, for any job that alters the opening or changes the egress path. We handle Palm Beach County permit submission, schedule inspection, and pass it - included in the written price, not added later. If your job is glass-only replacement in the same frame, permitting may not be required; we verify that at survey and tell you upfront. Call (561) 200-8592 to confirm your permit status.
