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

• Impact laminated glass delamination in the MG-Impact 300 series. The PVB interlayer between glass lites can fog at the edges after five to seven years of Lantana’s salt-air exposure, especially on east-facing openings within a quarter-mile of the beachfront corridor. We see this more often on MG-Impact 300 horizontal rollers than on fixed picture units because the sliding sash flexes slightly in wind gusts, stressing the seal. Our fix: remove the sash, document the delamination with photos for your record, and install a replacement laminated lite with a marine-grade silicone primary seal and butyl secondary seal per the Haven Standard. We do not attempt to “repair” delaminated impact glass - the unit must be replaced to maintain its Miami-Dade NOA rating.
• Corroded balance shoes in MG-Impact 100 single-hung windows. The nylon balance shoes in early MG-Impact 100 production runs absorb moisture and swell in Lantana’s summer humidity, causing the sash to stick or drop. We replace with stainless-steel-reinforced balance shoes from the same OEM supplier Mr-Glass uses, or with an upgraded aftermarket shoe with a 316 stainless pivot bar if the original is back-ordered. The sash weight and spring calibration are written on your quote before we order.
• Frame corner separation in MG-Impact 500 vinyl impact windows. Heat buildup between the exterior vinyl frame and the aluminum reinforcement channel causes the vinyl to pull at mitered corners, especially on south and west elevations. We measure the gap with feeler gauges, inject structural epoxy into the separation, and install mechanical corner keys where the original fusion weld has failed. If the aluminum thermal break has shifted, we replace the entire sash frame - not the whole window - to preserve the existing glass and hardware.
• Weep system blockage in MG-Impact 200 double-hung units. Lantana’s driving rain and pollen load clog the narrow weep channels in the MG-Impact 200 sill, forcing water into the wall cavity. We clear the weeps with compressed air and a borescope inspection, then enlarge the primary weep slots and add secondary pressure-equalization holes per Florida Building Code wind-borne debris requirements. We photograph the before and after for your documented photo record.
• Impact-rated screen frame fatigue in MG-Impact 400 sliding doors. The extruded aluminum screen frame on MG-Impact 400 two-panel sliders bows at the center lock rail after repeated impact from Lantana’s afternoon thunderstorms and wind-blown debris. We fabricate a replacement screen frame with a heavier 0.060-inch wall extrusion - not the standard 0.040-inch - and install stainless-steel corner stakes instead of the original plastic inserts. The mesh is always replaced; reusing old mesh voids the impact rating on the assembly.

Our Mr-Glass Impact Windows & Doors Process

1. 1
   Measured survey. Sonia Raman or a verified crew member arrives in uniform with license number visible, measures every rough opening to the sixteenth, and records frame squareness, sill level, and wall thickness. You keep the measured survey; it becomes the basis for the written quote.
2. 2
   Diagnostics with documentation. We identify the Mr-Glass series, manufacturing date code, and failure mode. Photos go to your file before we discuss solutions.
3. 3
   Parts decision. OEM Mr-Glass parts when available and cost-effective; quality aftermarket when lead times exceed three weeks or when the aftermarket part exceeds OEM spec. We write the part number, source, and price on the quote - no surprises.
4. 4
   Installation under Haven Standard. Verified crews, arrival on schedule, evidence on every job. We record U-factor and SHGC of every replacement unit before the contract is signed.
5. 5
   Testing and sign-off. Impact windows are operated through full travel, locks are torque-tested, and weep function is verified with water spray. You receive the documented photo record and the 365-Day Done Right Promise in writing.
6. 6
   Cleanup and final invoice. The invoice matches the quote line for line. Measure it right the first time. Everything after that is just paperwork.
