Replacement Windows in Largo Florida
Replacing windows can be a major expense when it comes to home renovation but they may be the single most important part of your project. Your windows need to protect your home from the outside elements as well as provide light and access to the outside. Original windows may not be up to new Florida building codes for wind debris zones. If your home was built prior to 2010, chances are your windows wouldn’t pass a building inspection.
Our highly energy efficient replacement windows in Largo are designed with home protection in mind. The glass is made to keep the heat and moisture of our Florida climate out, while keeping your much needed air conditioning in. Windows are a barrier from intrusive bugs, inclement weather and high velocity winds. Don’t you want to make sure your home renovation is done right the first time and increases the value of your home at the same time?

Replacement Windows: All About Grids
Traditionally, grids were wooden mullions that made multiple small panes of glass into one large window. Technological advances in the window industry have made it possible to make and transport large windows, eliminating the need to piece together windows with mullions.
Presently, people still use grids to enhance the beauty of their windows. The grids can come in between the glass panes for easy cleaning. Alternatively, they can contour over the glass for a more traditional look.
