We recently had National Waterproofing fix our multiple basement leaks. They came highly recommended by our contractor, who had them fix his own family’s basement leaks. We could not be happier with all aspects of our job including a timely and accurate estimate, good communication and tidy and respectful work. Our project manager, Mark, was informative, knowledgeable and frequently checked in on the progress. The on-site team of three worked tirelessly throughout the day and sometimes into the later evening due to poor weather, while still taking time to smile and wave at our little girls watching from the back window. Our property was left clean and well prepared for the landscapers who followed. Though I am confident that I will never need their services again in this house, I would not hesitate to recommend them for any waterproofing job.
Thank you so much for everything, Derek & Heather C.

I have never endorsed products or services, but in this instance I would be remiss if I if I didn't comment on the performance on this company. Not only are they very professional, they are courteous and accommodating. Accolades to Mark, Doug and the boys for their services.

National Waterproofing was excellent! They provided a detailed estimation, answered all of my questions, did outstanding workmanship and followed-up after the work was complete. I definitely would recommend this company to anyone. My basement thanks you!
