Frequently asked questions

Infinity replacement windows rank among the best replacement windows in the industry. Infinity's Ultrex® fiberglass boasts 8x the strength of vinyl windows and have an acrylic finish 3x thicker than competitive options to prevent dings, scratches, and fading. An Infinity Replacement consultant can help guide you through the window replacement process to find the best windows for Pennsylvania weather by exploring energy efficient window options, window costs, and window styles.

Infinity Replacement serves locations across the Philadelphia area. If you live outside of our Philadelphia service area, we can connect you with a local Marvin dealer for your window replacement project.

Infinity installers work diligently to ensure a proper fit for your windows and patio doors. Your window installers will remove your old windows and prepare the space to install new windows. Your new windows and doors will be inserted, leveled, secured, and any gaps filled. During installation, we'll take care to disrupt as little as possible and keep your home clean — we'll even haul away your old windows.

Typical window replacement costs vary based on a variety of factors. The style, size, and design options you choose will impact window costs. An Infinity Replacement expert can tailor a quote for your specific home window replacement needs.
