"Fast Estimate , had many estimates from other companies and Waterproofing One was the best price for Us , Joe was very confident and knowledgeable and gave Us good suggestions for our leaking basement, the crew that installed the French drain inside were great, install looks very professional. I figured we’d have a mess to clean up after the install understandably. But wow they did an incredible job cleaning up afterwards. Not a speck, they even spent time cleaning off the driveway and front lawn. We have been through one major rain storm since the install and not a drip of water. So far so good , we are getting an expected 3” in the next 24 hours and it’s a relief to know I don’t have to stress about rain storms anymore!"

"The job/work couldn’t have went any better and smoother then it did, not to mention the cleanliness and customer service provided from beginning to end went above and beyond my expectations. Inside my basement they made sure objects and furniture were moved out of the way of the working area and covered for protection. They also made sure the walkways and paths used to remove debris out of the basement and new materiel into the basement were covered to prevent surfaces from getting dirty or damaged. Just overall a very thorough and diligent process from start to finish. I would highly recommended AJ Waterproofing and most certainly would rehire them for any future business if needed."

"AWS did an excellent job waterproofing my basement with a French drain and two sump pumps. They were a pleasure to work with, and I highly recommend them."

"We had Peter and his crew from Aqua-Dry come out and replace our basement French drain, and sump pump and waterproof the cinder block walls. We have had no issues since. Our basement was done in the Spring of 2016. I have recommended Aqua-Dry to multiple friends. Peter stands by his work."

"The best basement waterproofing service you will ever hire. This company installed a French drain around the perimeter of my Philadelphia townhome basement and parged the walls. Mike is an expert and assured us everything would go well and it did. The crew were neater and more careful than house painters. I couldn’t believe how quiet, clean, and professional they were. I strongly recommend this company."

"My basement was getting wet every time it rained.. I called and was able to have an inspector come out right away for a free estimate. Everyone was so nice and very professional. I now have a dry basement! I would highly recommend them if you are in need of any waterproofing or foundation services!"

"Very impressed with the prompt response to my request to waterproof the basement. Patrick spent time to detail the French drain and sump pump project and explained what to expect. The crew arrive at 8 am and worked all day to about 5 pm. Very labor intensive, hauling out concrete, hauling in 5 gallon buckets of gravel & cement up & down the basement stairs. 32x22 French Drain perimeter and sump pump with battery backup installed in 1 day. The entire basement and outdoor area was cleaned after the work, even the driveway was washed down. About 4-5 guys showed up and Fernando was the foreman on the job. They worked very hard and were courteous. I had a debris pile that they were able to haul as well. It was not a cheap job, but there were no surprises. I was aware of the cost after the quote and with the amount of work involved, I am extremely satisfied. Thank you for your professionalism and expertise."

"I had a previous company come in to waterproof my basement and they charged me more than Once and Done and did a horrendous job. They didn't do it correctly and more mold grew. Once and down came in, tore out the previous work and put in their system and my basement is completely dry even during the wettest months & completely mold-free. They gave excellent customer service and priced the job VERY reasonably. This is an honest company and do super work. I would give them 10 stars if I could."

"This company did a first class job solving a basement foundation water infiltration problem in our commercial office building in Upper Bucks County, PA. A project manager came out to assess our situation; he came up with a proposed solution on the spot, provided us with a written proposal and sample photos of other similar work they had done. The work required excavating a small portion of the foundation on the exterior and filling a crack in the foundation wall down to the footers. The crew came out as scheduled and completed the job in a single day as predicted. Some follow up tweaks were needed, and I'm happy to say that the customer service team and follow up crew responded promptly and made some necessary adjustments to button up the job as promised. This is a first class operation and I do not hesitate to recommend this outfit to other colleagues and property owners needing this service."
