Mr-Glass Energy-Efficient Windows in Davie: What to Know First

We install and service Mr-Glass energy-efficient windows in Davie as an independent Mr-Glass service provider, with most measured surveys scheduled within two business days and written quotes delivered before any work begins. Typical retrofits in Davie run two to four hours per opening; full-frame replacements take a full day when structural reframing is needed. Our pricing starts where we say it starts - Haven Clause 1 means the measured survey and the written quote are the same document, and that document does not change once you sign it.

This page is for Davie homeowners who already have Mr-Glass products and need to improve thermal performance, replace failed insulated glass units, or correct installation errors that are showing up on their FPL bills. If your windows fog between the panes, your south-facing rooms overheat by 2 p.m., or your 2018-2021 Mr-Glass units are no longer meeting the ENERGY STAR ratings they shipped with, we can show you exactly why and what it costs to fix.

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

• Mr-Glass 300 Series: Seal failure in Low-E/argon IGUs. The 300 Series used a dual-seal polysulfide primary with a silicone secondary that degrades faster in Davie’s combination of high humidity and daily thermal cycling. We see this most often in Pine Island Ridge homes built 2016-2019. The argon escapes, the center-of-glass U-factor rises from 0.30 to 0.38 or higher, and condensation forms at the bottom edge by November. We replace the IGU with a warm-edge spacer unit, pressure-equalize to Davie’s 6-foot elevation, and document the before-and-after U-factor reading.
• Mr-Glass SolarShield tint delamination. The SolarShield line’s exterior tint film can separate from the glass after 5-7 years of UV exposure, particularly on west-facing elevations in Davie where afternoon roofline reflection intensifies heat. Delamination looks like a soap-film haze that cleaning will not remove. We do not attempt to repair tint film - we specify a replacement IGU with a hard-coat Low-E on surface #2 and a tinted interlayer, which eliminates the failure mode entirely.
• Mr-Glass 500 Series: Frame thermal bowing. The 500 Series vinyl profile uses a three-chamber design that can develop visible bow in the sash when interior and exterior temperatures differ by more than 35 degrees - common in Davie during January cold fronts when the interior is heated to 72 and the exterior drops to 40. The bow breaks the weatherstrip seal and creates a measurable air infiltration path. We correct this with a sash realignment, replace compression-set weatherstrip with a fin-seal hybrid, and verify with a smoke-pencil test at five points.
• Mr-Glass laminated glass edge corrosion. Mr-Glass laminated units with exposed glass edges - common in custom geometric installations around Davie’s equestrian properties - can develop edge delamination where moisture wicks into the PVB interlayer. This starts as a 1/8-inch dark line at the perimeter and expands inward. The energy performance is compromised because the laminated layer no longer provides the intended solar heat gain coefficient (SHGC) blocking. We source a replacement unit with proper edge deletion and a silicone edge seal, or recommend a framed conversion if the exposure is structural.
• Mr-Glass retrofit installation: Cavity condensation from missing or compressed insulation. We find this in Davie homes where Mr-Glass units were installed as retrofits into existing aluminum frames without proper backer rod and low-expansion foam. The thermal bridge at the frame perimeter causes interior condensation that homeowners mistake for IGU failure. Our fix is to remove the unit, inspect the rough opening with a borescope, install proper backer rod and closed-cell foam, and reinstall with a sloped sill pan - documented with photos at each stage under Haven Clause 4.

Our Mr-Glass Energy-Efficient Windows Process

1. 1
   Measured survey and thermal imaging. We arrive with a FLIR camera, a laser measure, and a manometer. Sonia Raman or a verified crew member records frame temperatures, air infiltration rates, and sightline measurements. You keep a copy of the survey.
2. 2
   Diagnosis with parts specification. We identify whether the failure is glass, frame, or installation-related, then specify OEM Mr-Glass replacement IGUs or quality aftermarket equivalents that meet or exceed the original U-factor and SHGC ratings. We note warranty-safe practices and flag any that would void remaining coverage.
3. 3
   Written quote with no variance clause. The quote references the exact measurements from step one, line-items every part and labor hour, and carries Haven Clause 1: the price on this document is the price on the final invoice.
4. 4
   Installation with evidence collection. Our background-checked, uniformed technician installs to the measured survey, photographs each critical step, and records final air infiltration and U-factor readings.
5. 5
   365-Day Done Right Promise activation. The job file - survey, quote, photos, test results, and warranty - is uploaded to your customer portal. If anything is not done right, we make it right. That is Haven Clause 5, written, not verbal.
6. 6
   Cleanup and documented handoff. We leave the work area cleaner than we found it and send you a link to your complete photo record within 24 hours.

We are not the only window company in Davie that handles Mr-Glass, but we are the only one operating under the Haven Standard with 18,000+ documented installations since 2012. When a Mr-Glass unit fails, you need a technician who knows whether the 300 Series seal failure requires a full sash replacement or just an IGU swap - and who will tell you honestly which it is, because the price difference is $340 versus $940.

Sonia Raman and our crew have worked in Davie long enough to know that Pine Island Ridge homes from the 1990s often need full-frame replacements, while newer construction in Davie Ranch can usually be handled with retrofits. We carry PGT, CGI, CWS, and ES Windows lines as well, so if your Mr-Glass product is discontinued or the lead time exceeds your needs, we can specify a verified equivalent with matching performance data.

Our technicians are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3. Calls are answered by a live person, 24/7. And every job leaves a documented photo record, because evidence is the only proof point we accept.
