Mr-Glass Door Installation: The Lantana Owner’s Guide
Mr-Glass door installation in Lantana typically runs $1,800-$4,200 for a standard single entry unit, depending on impact rating, frame material, and whether the rough opening needs reframing. We stock Mr-Glass hardware and keep common frame sizes on hand for homes along the Lantana beachfront corridor, where salt air accelerates corrosion in non-impact-rated components. Most homeowners realize something’s wrong when the door won’t latch flush, daylight shows at the jamb, or the sweep drags after a storm season - symptoms that usually trace back to frame shift, hinge fatigue, or seal compression in the glazing pocket.
Which Mr-Glass Models This Applies To
Mr-Glass produces three residential door series we see in Lantana: the MG-Impact line (rated HVHZ), the MG-Thermal series (non-impact, energy-focused), and the MG-Entry composite line. The label is stamped on the hinge side of the frame, usually behind the strike plate or on the top rail of the glass insert. If the label’s worn off, measure the slab thickness - MG-Impact runs 1¾ inches, MG-Thermal and MG-Entry run 1⅜ inches - and check the glazing edge for a laminated interlayer (impact) or a single seal (thermal).
We install OEM Mr-Glass frames and sashes where the existing unit is intact enough to accept factory-matched components. For older MG-Thermal units from the 2015-2019 production run, we sometimes source equivalent-grade frames from our CWS and CGI lines when Mr-Glass has discontinued the exact profile, which happened with the MG-Thermal 2100 series in 2020. We document the substitution in writing before ordering, with U-factor and SHGC numbers attached, so the quote and the final spec sheet match. Sightline Windows & Doors Lantana is independently operated and not affiliated with Mr-Glass; we source through authorized distribution and maintain our own compatibility database.
Signs Your Mr-Glass Door Installation Is Failing

- The door sticks at the top corner in summer, then gaps in winter. This is frame racking from humidity cycling in the Lantana climate. The MG-Thermal series used a wood-composite jamb in pre-2018 units that swells ⅛ to 3⁄16 inch seasonally. We check plumb with a 6-foot level and replace with aluminum or composite that doesn’t move.
- Water pools at the sill after a storm, even with the door closed. Theweep holes are clogged, or the sill pan was never flashed correctly at original install. On MG-Impact units, the three-stage drain channel compresses with age; we pull the threshold, clear the ports, and replace the cap if it’s cracked.
- The multipoint lock won’t throw, or the handle spins. The gearbox in the mortise mechanism strips after roughly 8,000-12,000 cycles. We see this most on MG-Impact doors with heavy glass where owners use the handle to pull against wind pressure. The fix is a matched gearbox replacement, not a new handle.
- Condensation between the glass panes that doesn’t wipe off. The insulated glass unit (IGU) seal has failed. In Lantana’s UV exposure, this happens at 10-14 years on average, sooner if the door faces west. We measure the daylight opening and order a replacement IGU to the exact sightline dimension.
- The sweep or weatherstrip pulls away from the jamb. Adhesive failure from salt air. We replace with marine-grade bulb seals and mechanical fasteners, not the original press-in vinyl, which we stopped using on Lantana installs after 2019.

AfterReplacement Cost & What’s Included
| Scope | Price Range in Lantana |
|---|---|
| Standard MG-Thermal entry door, slab and frame, installed | $1,800 - $2,800 |
| MG-Impact rated entry door, HVHZ, installed | $2,600 - $4,200 |
| IGU replacement only (glass swap, frame retained) | $480 - $720 |
| Multipoint lock mechanism replacement | $340 - $560 |
| Full frame reflash and sill pan replacement | $620 - $980 |
| Rough opening repair / reframing (if needed) | $400 - $900 |
The range depends on three things: whether the existing frame is square within ¼ inch, whether the wall is block or frame construction, and whether the HOA or municipality requires permit documentation. We pull permits where required and pass inspection before final invoice. Every job includes the measured survey you keep, the written scope with line-item pricing, and the documented photo record uploaded to your file. The 365-Day Done Right Promise applies to all Mr-Glass work - if the sweep pulls or the lock drags, we return and correct it under Haven Clause 5.
DIY or Call Us?

There are two things a homeowner can safely check before calling: whether the hinge screws are tight (a #3 Phillips, usually) and whether theweep holes at the sill are blocked with debris. Beyond that, door installation involves risks that justify a trained crew. A standard entry slab weighs 80-140 pounds; an impact-rated MG-Impact unit with laminated glass can exceed 200 pounds. Improper lifting damages the frame corners and voids the manufacturer’s warranty. Reframes require structural assessment - we’ve found compromised king studs in three Lantana homes this year where water had been entering for years unseen.
Measure it right the first time. Everything after that is just paperwork. Call (561) 461-2062 and we’ll schedule a measured survey. The written price we leave with you is the price on the final invoice.
FAQs
With proper installation and maintenance, 18-25 years for the frame, 10-14 years for the IGU seal, and 8-12 years for the multipoint hardware. Salt air accelerates hardware corrosion; we specify stainless or coated components on every Lantana install. Call (561) 461-2062 for an exact assessment of your unit - estimates are free.
Sometimes. IGU seal failure, hardware wear, and weatherstrip damage are repairable. Frame rot, structural racking beyond ½ inch, or delamination of the impact layer require full replacement. We diagnose on site and quote both options where both exist. Call (561) 461-2062 for a free second opinion.
A standard replacement in an existing, square opening takes one day. If the rough opening needs reframing or stucco repair, plan for two days plus cure time before finish paint. We arrive on schedule, work the full day, and leave the documented photo record before we leave. Call (561) 461-2062 to check availability.
We carry MG-Impact and MG-Thermal hardware, common sweep profiles, and weatherstrip for the series we see most in Lantana. Full slabs and frames are ordered to measured sightline dimensions - we don’t guess on size. If your unit is from the discontinued MG-Thermal 2100 series, we stock the CWS equivalent that matches the performance spec. Call (561) 461-2062 and we’ll confirm compatibility before scheduling.
