See a problem? Let us know!
They offer a great service, they even emptied out my garage and put up plastic sheets before getting started. Left the place cleaner than they found it! AJ presented a few options and explained each one. He was prompt and worked quickly and efficiently with his crew. The job went as planned and I have nothing but praise for the quality of the work performed. If you are looking for an expert, A J Waterproofing is the way to go!
Family Owned and Operated for Over 30 Years

I would like to take this time to introduce myself, A.J. DiElsi and my company, A.J. Waterproofing.

I have been waterproofing basements since 1976! This is the only business I do. We are a family owned and operated company. We do not have salesmen; I come out and meet, talk and diagnose the water problem with you personally. We do not have multiple crews. I am on each and every job, this way, I know every job is done to perfection.

We have been in business for 30 years and we service the entire Mainline and surrounding areas. We also do travel out of state, especially for our referrals. My business is built on referrals. We strive to please every to please everyone that we work for, therefore they pass our name along the way.

We are incredibly meticulous in our workmanship and leave the area cleaner than when we arrived. We have actually had homeowners; dig up our outside work because they did not believe that we had done anything. Everything in the garden had looked like it was never touched! Every homeowner always comments on how neat our crew is and that they are amazed at the job we did!!

We do all phases of waterproofing inside and outside and we do both residential and commercial. We have a transferable lifetime guarantee with every job.
