Drain Tile System in Chicago, IL

This company is one of the most professional entities I have ever dealt with. From the very knowledgeable (yet not pushy) salesman, to the administrative office support, to the workmen, our experience was nothing but pleasant and seamless. Communication was open and consistent, with service reminders calls, a call just before the workmen arrived, and a follow-up call to assess our satisfaction. And the workmanship--excellent!! Everything was handled according to code, with a permit pulled, and the final product passed city inspection with flying colors.

After my dad passed away this year, we knew we had to do something about a very leaky basement in order to sell the house. It was an emotional time going through my parents' belongings and the last thing I wanted was to worry about the basement. We had two foundation cracks filled in my parents' home and then had Perma-Seal install an entire drain tile system. The impending work was explained to us in language that we could understand and then everything went exactly as planned.

Thanks to Perma-Seal's immaculate, accurate, high-quality work, our basement is now bone dry! And the lifetime warranties and transferability to new owners gives us peace of mind as we sell my parents' home.

I would definitely recommend Perma-Seal to all of my friends and family. This is a top-notch company.
