About Us
Our History
Window Perfections in Altoona was founded on July 5, 2000 by Mark L. Stouffer. As a proudly family–owned and operated business, it has grown from its early days into a respected local specialist in custom Okna replacement windows and patio doors. Rather than relying on subcontractors, the company employs a small, full‑time installation team, which fosters consistent quality and care.
Under the guiding philosophy of “Windowology”—a fact‑driven, educational sales approach championed by Stouffer—the business emphasizes empowering homeowners with transparent information rather than pressure tactics. Over more than two decades, Window Perfections has completed hundreds of installations across Blair County, earning an A+ rating from the Better Business Bureau and multiple local award recognitions.
Their longstanding commitment to energy efficiency, exceptional craftsmanship, comprehensive warranties, and customer satisfaction has cemented their reputation as a trusted choice for window replacement in the Altoona region.
Our Awards
Since 2015, Window Perfections has earned the Angi Super Service Award every single year, placing them among the top-performing home service providers in the country. This award is reserved for companies that consistently receive high ratings in areas like quality, professionalism, punctuality, and value. With a near-perfect customer satisfaction record, the team has proven its commitment to excellence time and again.
Winning this award year after year is no small feat—it requires consistent delivery of top-tier service and dedication to doing the job right the first time. For homeowners in Altoona and the surrounding areas, it’s a clear sign that Window Perfections can be trusted not just once, but over the long haul. The recognition is more than a badge—it’s proof of a company culture built on quality, trust, and results.
As The Windowologist says,
“We don’t mean to brag, but only 5% of window contractors are chosen for The Angi Super Service Award and you win it consistently years in a row…well, you must be doing something right!”
