About this service

Installing impact windows involves removing your existing frames and securing heavy-duty, reinforced glass units into your home’s structure. The final cost depends on the size of your openings, the type of frame material, and the specific energy-efficiency ratings you choose. Labor requirements also play a major role in the total investment.

Summer heat puts a massive strain on air conditioning systems. Impact windows help manage indoor temperatures by blocking out intense solar heat, which means your cooling system does not have to work nearly as hard. This efficiency is a huge benefit during the hottest months, helping you maintain a cool home without excessive energy waste.
