Mr-Glass Construction in Casselberry, FL | Sawyer Remodel Orlando
We’re Sawyer Remodel Orlando, a Casselberry General Contractor and independent Mr-Glass service provider working across the surrounding area. If you need Mr-Glass windows or doors installed, repaired, or replaced, call (850) 809-0306 for a free estimate. The thing that sets our Mr-Glass work apart here is simple: we know Casselberry’s houses, its humidity, and its water table, and we know where Mr-Glass products fail because of them. Our window crews pull permits, order genuine parts when it matters, and give you a written price before any work begins.
Why Casselberry Residents Choose Us for Mr-Glass Service

Mr-Glass windows and doors are built for Florida weather, but no window survives Casselberry’s climate without proper installation. Our crews have years of independent Mr-Glass experience on 1960s-to-1980s slab-on-grade homes throughout Casselberry, and we’ve seen how these products hold up under subtropical heat, afternoon downpours, and hurricane-force wind. Luca Romano, our owner and lead contractor, trained at Los Angeles Trade-Technical College and has spent nearly two decades putting that training to work across Central Florida. He built this crew on a simple rule: show up when you say you will, and leave the jobsite cleaner than you found it. We’re not manufacturer-affiliated. We’re not authorized dealers. We’re local tradespeople who know Mr-Glass windows well enough to tell you when a repair makes sense and when replacement is the honest call.
Every job we run in Casselberry follows the Relay Visibility Guarantee: a written price before work starts, live arrival time tracking, and before-and-after photo updates. You’ll know who’s walking through your door before they get there because every tech is background-checked and uniformed. And our 365-Day Done Right Promise means if something isn’t right after the job closes, we come back and make it right.

Common Mr-Glass Construction Problems We Solve in Casselberry
Here’s what we see most often when homeowners in Casselberry call us about their Mr-Glass windows and doors:
- Failed impact glass seals: Condensation between the panes is the telltale sign. Casselberry’s humidity accelerates this, especially on lakefront homes near Lake Kathryn and Sausalito where morning sun hits the glass hard. Once the seal goes, the insulating gas escapes and the window stops doing its job. We replace the glass pack with genuine Mr-Glass components when the frame is still sound.
- Corroded and seized sliding door rollers: Mr-Glass 5000 Series sliding glass doors are heavy. When the original rollers corrode from high-water-table moisture and humidity, the door becomes nearly impossible to move. We’ve replaced dozens of roller assemblies on Casselberry sliders, and in most cases an aftermarket roller set gets the door gliding again for a fraction of the cost of a full door replacement.
- Stripped frame screws and warped vinyl: The Mr-Glass 6000 Series single-hung windows installed on many 1960s-1980s wood-frame Casselberry homes are prone to this. The vinyl warps in the heat, the screws strip in the soft old wood, and air leaks open up during afternoon thunderstorms. We re-secure the frames with new fasteners, replace the weatherstripping, and reflash where necessary.
- Cracked exterior glass from flying debris: Tropical storms don’t give much warning. Non-impact Mr-Glass units on homes that were never retrofitted for wind codes crack when branches or debris hit them. Often we find the original flashing was installed wrong, which created a water path behind the frame. We replace the glass and correct the flashing in the same visit.
- Unpermitted window openings found during remodels: We’ll get into this more below, but Casselberry has a specific problem with unpermitted Mr-Glass installations from previous decades. When the city’s inspectors flag non-compliant openings, we’re the crew that fixes them properly and pulls the permits to prove it.
Mr-Glass Service in Casselberry: What Local Conditions Mean for Your Equipment

Here’s the thing about Casselberry that most window companies won’t mention because they don’t do enough work here to know it: the city’s older neighborhoods, particularly around Lake Kathryn and Sausalito, are full of 1960s-to-1980s slab-on-grade homes that had windows and doors added over the years without permits. Homeowners expanded rooms, enclosed porches, and swapped in Mr-Glass units on openings that were never reviewed against current wind-load codes. When those windows fail or a remodel begins, the city comes looking, and the homeowner is left holding a costly correction order. This is Casselberry-specific because the combination of aging slab foundations, wood-frame construction, and decades of unpermitted work created a backlog of non-compliant openings that you simply don’t see in newer cities like Oviedo or Winter Park at the same rate. Our crews have handled enough of these corrections to know exactly what the building department wants to see: proper anchoring, code-rated glazing for the wind zone, and documented permits. Good work doesn’t need a speech, it just needs to hold up, and the city’s inspectors seem to agree when they sign off on our work.
Manufacturer warranties on Mr-Glass products cover materials and workmanship from the factory. They don’t cover failures caused by improper installation, which is what we find on a steady share of Casselberry homes. If a previous installer skipped flashing or used the wrong fasteners, the window isn’t warrantied. That’s why we treat installation and repair as the same discipline: correct the opening, use the right anchors, flash it properly, and the window works for decades.

FAQs: Mr-Glass Construction in Casselberry
Yes, and in most cases your windows need to meet Florida Building Code wind-load standards for Central Florida, not the stricter Miami-Dade standards unless your specific street is in a designated high-velocity hurricane zone. Casselberry’s building department enforces the Florida Building Code, which requires impact-rated glazing or shutters on new window installations. We pull permits on every installation and our work passes inspection. Call (850) 809-0306 if you’re unsure what your home requires, and we’ll check before quoting.
Yes, and this is one of the most common calls we get from Casselberry homeowners. The issue is almost always the rollers: either they’re corroded from the high water table moisture, or they’ve seized from years of grit and humidity. We clean the track, replace the roller assemblies with aftermarket units designed for heavy doors, and adjust the frame so the door glides. If the door frame itself has shifted from the slab settling, we’ll address that too. Most repairs run a few hundred dollars and take under two hours. Call (850) 809-0306 for a specific quote.
It can, but there’s a catch: the insurance discount applies only when the impact windows are properly permitted and documented. We’ve seen Casselberry homeowners install impact windows without permits and then wonder why their insurer won’t credit them. When we install impact windows, we pull the permit, pass the wind mitigation inspection, and hand you the paperwork your insurer needs. If your home already has unpermitted impact windows, we can verify the installation and help you navigate the retroactive permit process. Call (850) 809-0306 for a free consultation.
For a 1970s wood-frame home in the Lake Kathryn area, we typically recommend the Mr-Glass 7900 Series Impact Windows for Bathroom Remodeling in Casselberry and other projects. Those homes sit close to the lake, get heavy morning sun, and face real wind exposure during tropical storms. The 7900 Series carries the impact rating you need for code compliance and insurance credits. The key is the installation: the original wood framing around the windows needs to be inspected for rot before we anchor the new units, and we’ll replace any compromised wood during the install. Call (850) 809-0306 for an on-site assessment.
This happens more in Casselberry than almost anywhere we work, especially in the Lake Kathryn and Sausalito neighborhoods where 1960s-1980s homes had windows added without permits. Here’s the sequence: we assess the opening against current wind-load codes, flag any structural issues, then work with the building department to pull the correct permits and bring the installation into compliance. Sometimes that means re-anchoring the existing Mr-Glass unit; sometimes it means full replacement. Either way, you end up with a documented, code-compliant window and a cleared permit. Call (850) 809-0306 and we’ll walk you through it.
