Recommended Customer Reviews
We had water coming up through a basement floor in heavy rains and everyone had a theory as to why. Paul and his team diagnosed the problem thoroughly, did the work promptly, and kept the cost to the minimum amount reasonable. We've been through two heavy rains: no water. I'd absolutely work with this team again.
Paul and his team were a dream to work with. Both Paul and the crew approached my exterior footing drain project methodically and were always available to answer my questions. They even corrected a problem done by previous work. Will plan on reaching out again for our backyard drainage project. They came highly recommended from a neighbor and now I would happily recommend them too!
The team at Allied Waterproofing exceeded all my expectations. Paul approached our problem thoughtfully and provided a creative yet economical solution. The men doing the work arrived on time, kept me informed as to what was going on, and left the yard in immaculate condition. Erin kept me informed as to when to expect the job to be done. She promptly responded to my questions. I could not be more pleased.
Excellent team at Allied Waterproofing. Erin is a superstar at the front office. She responded to calls and updates. Paul knows his business with repairs and fair estimates. We had to ""problem-solve"" some issues with our front driveway drains. No ""up-sale"" or solutions we did not need. The Crew was in and out like they had never been there. Start with Allied for drainage issues!
Vanessa I.Prompt and friendly! Paul was a delight and I was able to work from home without issue.
Allied has done two projects for us to waterproof our basement -- one large job involving 1-1/2 sides of our house, and one small job involving a spot leak where water collects on the other side of the house. All aspects of the work they do is simply phenomenal. They diagnose the problem, develop a solution (sometimes more than one to choose from), provide a reasonable bid, and carry out the work. At each step of the process you know you are dealing with total professionals. The crew that came out were knowledgeable, professional, and extraordinarily efficient. For any kind of work we have had on our home, I have never seen a crew work so hard and do the work so well. Everything was done just right. I wish I could give six stars. Recommended X 100!
Paul and his team did a great job installing two different French drains in our yard. Erin was so responsive and a great contact point for the company. Vlad and his crew were absolute animals!! They did such a great job and only took a day and a half. They also did a great job of cleaning up after and making the seams in the yard as invisible as possible. They were extremely competitive with other bids we received and actually bested the other bids by a long shot. I would highly recommend Allied to everyone I know. Great company, great employees and very affordable.
Michael E.Had Allied out to get quoted for a project. Had every opportunity to sell me an expensive solution to my drainage issue but instead offered sound advice and saved me thousands. Super knowledgable and honest. Will absolutely be turning to them for all my waterproofing and drainage issues.
Ben S.Reliable, dependable, easy to work with and offered the best price. I had a sewer that needed a liner. The estimate process was easy. I had to coordinate the estimate while out of state. Actual work was done as the owner/estimator had described. Inspection passed with flying colors. Never thought I'd say that I'm happy a sewer liner installation.
We recently purchased a new construction home. The home itself was great, but the backyard looked to have drainage issues. Allied Waterproofing was responsive, honest, professional and super knowledgeable. Would highly recommend!
