Once & Done Waterproofing Solutions, LLC

We have a 150-old house with a small, unfinished, and very damp basement (but no standing water). In the summer the humidity was continuously over 70%. We bought the largest dehumidifier you can get at a home improvement center, which was unable to get the humidity below 60%. We just wanted to be able to store things there without having them ruined. We had three contractors look at it and make recommendations. The first proposed an elaborate and very expensive foam insulation approach (though he described it as "relatively cheap"). To boot, a number of his reviewers described results that were not as promised and complained that getting follow-up service was difficult to impossible. The second had a one-size-fits-all approach whereby he digs a trench and installs drainage pipes all around the perimeter. This would not only have been unnecessary, but almost certainly would not have solved our problem, which was extremely moist air. The third was Once-and-Done Waterproofing, and the owner, Jeff Johnson, proposed to install a powerful commercial-grade dehumidifier, for what seemed like a very reasonable price. We went with him. The results have been fantastic! This unit easily keeps the humidity in the mid-30% range and completely solved our problem. Jeff is a no-nonsense, straight shooter who does exactly what he promises, when he promises it. His office manager Shawn was great at communication and scheduling. Jeff gives you his personal mobile phone number and he actually answers it! We could not be happier with the results!

Jeff delivered what he promised and so far there are no issues. We needed a bigger grate by our basement door and Jeff came back and installed it without any problems. The work was done quickly and efficiently.

They are professional, honest, and finished in a timely manor.

Only years ahead will prove the value of the service being that it is waterproofing of basement system installed, but thus far I am satisfied.

He did a great job

Called Jeff after I talked with and met with 2 of the big name companies. Jeff came to give me a quote on time when promised. After looking over my job, He explained what work needed to be done and what was not needed,. Fix the source of the problem and don't waste money on work that don't need to be done is what Jeff told me. Glad I listened to him. Jeff and his crew came on a Saturday finished in 1 day. Job was done neatly and crew was very professional!

Jeff came in and gave us an estimate which he stuck to. He also arrived on time and did the work in a timely and professional way. He was also pleasant and fair to deal with.

Work was done on time and with high quality at the price I was quoted. I am very pleased with the results. I would highly recommend them.

I highly recommend this company. Our basement hasn’t leaked since (knock on wood). The guys were so nice and really did a great job. I was also VERY impressed with how clean they left the place. Oh, and the price was great too.

Called and showed up the next day and follow up the next day of meeting. Very courteous, polite and very professional. Went above and beyond expectation. save us money.
