Family Owned and Operated for Over 40 Years

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

I have been providing waterproofing basement services since 1976! Basement Waterproofing 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 40 years and we provide basement waterproofing, walls parging, sump pump installation, french drains, downspout corrections, outside grading and more to the entire Mainline and surrounding areas. We also do travel out of state, especially for our referrals. My business is built on referrals form satisfied customers. We strive to please everyone that we work for, so they will 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.
