Our Company

Perma-Seal was founded in 1979 by Roy Spencer. After working for two other large waterproofing companies, he was dissatisfied with the low ethical standards and the “patch now and service ‘em later” repairs that were commonplace in the industry. It was then that he decided to build a company that could provide permanent repairs and stand behind that work with integrity. Today, over 30 years later, Perma-Seal has become the world’s largest residential waterproofer and has helped nearly 250,000 Chicagoland homeowners achieve permanently dry basements.

Perma-Seal's methods of repair are nationally recognized as the industry leader in permanent basement waterproofing and foundation repair solutions. Our exclusive, patented systems allow many options that address your individual challenges without making your need to fit the one solution. Our time tested repair methods, along with our excellent service have been the reason why Perma-Seal has been around for so many years.

At Perma-Seal, our commitment to excellence and integrity remains our #1 priority. We are continually improving our products and procedures to achieve our goal of total customer satisfaction and making your basements and crawlspaces a valuable part of your home. Not only are our patented methods of repair nationally recognized as the industry leader in basement waterproofing and foundation repair solutions, but no other Chicagoland contractor can offer these permanent solutions for your home.

Perma-Seal offers the best warranties in the industry so that you can have the peace of mind of knowing that you’ve made a wise investment in your home with a solid, reputable company. All of our warranties are written, clear, and fully transferable to any new owners, and many are for the life of the structure.

No subcontractors; only Perma-Seal trained, experienced and uniformed staff perform work in your home. Not only do all of Perma-Seal’s employees undergo initial background checks and drug screening, but all of our staff attend weekly training classes to cover technical, safety and customer service issues. It is critical that we, and you, know who will be working in your home.

Perma-Seal has received many awards and accolades throughout the years. We are presently accredited with an A plus rating from the Better Business Bureaus in Chicago and Northwest Indiana; we have also won the Bureau’s Complaint Free Award as well as their prestigious Torch Award for Marketplace Ethics. Perma-Seal has won Angie’s List Super Service Award for the last 9 years, and Roy Spencer was selected in 2005 as the Ernst and Young Illinois Entrepreneur of the Year in the Consumer Product’s category. Roy was also featured as the waterproofing expert on Pam Zechman’s CBS news exposé. Its achievements like these that give our customers Peace of Mind and truly make Perma-Seal “Known best for being Better”!
