The name Chicago has trusted since 1979

Roy Spencer started Perma-Seal on one idea: permanent repairs at a fair price, and standing behind the work without equivocation. More than 45 years and 500,000 homes later, we still run on it.

Our story

A better repair, done with integrity

Roy Spencer started Perma-Seal in 1979 with a plain idea most contractors would not commit to: fix the problem permanently, charge a fair price, and put the promise in writing. Integrity was never a slogan for him. It was simply how he decided to run the business.

More than four decades later, Perma-Seal is the name Chicagoland and Northwest Indiana turn to for dry basements, solid foundations, and healthier homes. The standard has not slipped, and neither has who picks up when you call.
