Lowering Your Monthly Heating & Cooling Costs with Replacement Windows in Connecticut

Each year that you continue to live with older windows and doors, you could be losing up to 33% of your homes energy. Over time and through constant wear and tear, your existing windows and doors have spawned cracks, leaks, and gaps that allow for an exchange of energy. By replacing them with Renewal by Andersen® windows and doors, which utilize insulated Fibrex frames and advanced glass packages, that energy exchange is eliminated and you’ll see an immediate drop in your heating and cooling costs.
