Installing new replacement windows? We'll help you do it right!

Window choices are not simple, nor are they “standard”. There is a lot to consider. From style considerations, material choices (vinyl, fiberglass, wood, aluminum) and with 30% of a home’s energy potentially lost through windows, you also have to consider energy technologies (glass packages, Low-E, efficient seals, frame materials). Our team will help you navigate these replacement window choices for a customized, long-term solution for your home. Whether you’re considering window installation or window repair and maintenance, knowledge is power.

Infinity Fiberglass Windows: A Lifetime of Durability, Energy Efficiency, & Beauty

Infinity's fiberglass windows are not only beautiful, they are built to withstand the test of time with an emphasis on durability. Made from Ultrex fiberglass, these products deliver lasting performance by resisting warping or fading while also ensuring safety against cracking due in part because they're not susceptible like other materials such as vinyl.
