Top-Notch Installation of the Industry’s Finest Fiberglass Windows Offered to Homeowners in Lenexa, KS

Exterior shot of double-hung window with black fiberglass frames installed in brick wallWhether you’re still researching the merits of fiberglass windows or you’re already convinced that you want fiberglass replacement windows for your home in Lenexa, Kansas, make sure you explore the options available from Johnson County Siding & Window Co. We take great pride in installing replacement windows from Marvin®, an award-winning manufacturer with a long-established reputation for innovation and exquisite craftsmanship.

Why Our Fiberglass Windows Are a Cut Above the Rest

Fiberglass windows are a worthwhile investment for homeowners who want to replace their windows one time and feel confident that they’ve made a smart, low-maintenance choice. Fiberglass is the ideal window-frame material because it doesn’t expand and contract with temperature changes, and it doesn’t absorb moisture. This means it won’t swell and shrink as the years go by, which could put your all-important window seal at risk.

However, Marvin® replacement windows are even better suited to the climate in the Lenexa area because of their superior construction and use of the manufacturer’s proprietary Ultrex® fiberglass. This frame material is eight times stronger than vinyl and three times stronger than wood. Why is that significant? It allows Marvin to produce windows with remarkably slender frames that are strong enough to securely hold large expanses of energy-efficient glass, thus maximizing your view of the outdoors.

Marvin also understands the importance of providing plenty of customization options, so homeowners can enjoy long-lasting and energy-efficient fiberglass windows that suit their tastes to a T.

Installation Expertise You Can Count On

When you partner with us for your window replacement project, you’ll be teaming up with a Marvin Authorized Replacement Contractor, which means we’ve demonstrated our commitment to following the manufacturer’s installation specifications. Moreover, we’ve been installing windows in Lenexa and surrounding communities for more than 40 years while maintaining a stellar A+ Better Business Bureau rating. We also offer a five-year workmanship warranty on top of the industry-leading product warranty you’ll receive from the manufacturer.
