The Ranking
Our top 5 window companies in Miami
Miami homes ask a lot of their windows. Much of the housing stock is concrete block from the 1950s through the 1980s, with older aluminum frames and sliding glass doors that were not built for modern wind loads. Hurricane season, salt air and a long cooling season mean the glass does three jobs: it has to survive a storm, keep the air conditioning from working overtime, and hold up to sun that bleaches fabrics. That is why most replacement work here is impact glass, and why homeowners also ask about insurance credits for wind mitigation.
When you compare quotes, look for two ratings on every opening. Impact products must carry a Florida or Miami-Dade product approval, which the installer should list by number on the contract. Energy performance is shown on NFRC labels and Energy Star ratings, which tell you how much heat the glass lets through. A low U-factor and solar heat gain coefficient matter more in Miami than in cooler cities.
Permits are part of almost every window or door replacement in Miami-Dade, and the contractor normally pulls them. Condo and association buildings often add their own rules for colour, track style and work hours, so ask the installer whether it has worked in your building. If your home was built before 1978, old paint on window frames may contain lead. The US EPA's Renovation, Repair and Painting rule requires contractors who disturb that paint to be certified, so ask about it when you have wood frames or older trim.
Check the licence before you sign. Florida licenses window and door installers through the Department of Business and Professional Regulation, and many installers hold a certified general contractor licence, shown with a CGC prefix. You can look up any licence number on the DBPR website and see whether it is active. We found one company in this ranking that publishes its licence number, so ask the others for theirs.
We checked each company on Google Maps and then on its own website. All five have 4.5 stars or better, at least 50 Google reviews, an operating business status, a real working website, a street address in Miami and a company logo. We left out big-box stores, glass repair shops, lead generation sites, virtual offices and companies whose websites we could not load. Several larger Miami window companies had addresses in Doral, Hialeah, Cutler Bay or Miami Lakes, which are separate municipalities, so they are not on this list.
