"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!"

"We recently used AJ's Waterproofing Services to fix our water issues in our basement and we couldn't be happier with the job him and his team did. It was very apparent from our consultation with him that he is the ultimate professional. He spent over an hour and a half with us explaining the issues at hand in our basement and the different options we could go with to remedy the situation. It never once felt like he was out to oversell us or take advantage of us. We knew very quickly he was the man for our job. The day of the French drain install, he sent us multiple updates throughout the day. After they were done for the day, they thoroughly cleaned the area. There were no traces of dust and debris from where they dug up the concrete. We just had a major rain storm and we had no water in the basement. I would highly recommend AJ's Waterproofing for all of your water issue needs."

"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."

"Make sure you get a quote from this company before signing with others. These guys are fantastic. This is the best company I have worked with to do work on my house and they are the gold standard for how work should be done. They were on time and early to do the work. They got it done fast (2 days to install the trench and drain, spray for mold, and vapor barrier basement). They used their own employees and didn't subcontract. They kept everything clean wiped the floor and walls with a bucket and made sure not a spec of mud was on the ground when they left (looks better than when they came). Their quality of work is excellent and you could feel the difference and see it in the basement before they left. Now let's talk about price. They beat the quotes or matched the price from other companies (some companies were new and more expensive for less and some have the same price but worse reviews). After seeing the work I wouldn't give my money to anyone else. Please check these guys out before going with anyone else."

"Mike and his crew were great to work with. They are reasonably priced, professional, and got the work completed quickly. Basement waterproofing was done in one day! They left the basement clean. I would recommend their services!"

"From the beginning of the project to the end, Basement Gurus made the process feel painless. They gave me a clear understanding of what remedies were necessary to fix my foundation and ensured that all of my expectations would be met. The contracted workers were timely, considerate, clean, and personable. I strongly recommend Basement Gurus for any waterproofing work and will be using them as often as necessary in the future."

"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."

"I felt so confident in my salesperson’s level of knowledge & level of sincerity that I didn’t bother getting other quotes. This is rare for me. The salesperson, Dave Shiflette came out for an initial visit & advised me to address external gutter & drainage issues before addressing it from the inside. He advised me to first try to keep water away from my basement before spending money to redirect it away. This earned my trust- big time!!! I addressed the above ground issues & still got water in my basement. It was time to admit defeat, accept that it was due to hydrostatic pressure (water coming in below underneath foundation), and call in the experts! The crew was great! The foreman updated me during every major step. Things were clean for the most part. I don’t hold the crew responsible for dirt & minor mud because they had to go to/from mud due to recent rain. Still- There is room for improvement on the dust area. I felt so confident in my salesperson’s level of knowledge & level of sincerity that I didn’t bother getting other quotes. This is rare for me.

There’s a bit of improvement to be left in the dirt/dust area, though. It’s my only gripe. I did have to run my shop vac through furniture & other materials throughout two floors affected. Again- we did have rain beforehand, but we did provide a clear clean driveway access to minimize dirt entry into our home. On to more important matters… It rained for 4+ days about 7 days after our install. We’d normally get about 200- 500 gallons of water in our finished basement during such a storm. We got zero water puddles above ground during the storm!!! I did panic because no water made its way to the sump pump well, while we got a few wet spots on the above-ground area. These “wet spots” were just damp areas in the concrete. They weren’t puddles of water. I panicked & sent messages to our salesperson. He forwarded to management. They sent out their most experienced foreman who determined the the system was working (after testing & showing me a live result with a water hose pumping water through the area of concern). The verdict: concrete takes 30 days to fully cure. The spots haven’t cured yet! I was so relieved!!! The system works! My days of torture in the basement are over! My instincts to go with the salesperson were right!!! I’d like to thank Jay for assuring me that they are a family business that cares about clients, cares for their customers & STANDS BEHIND THEIR PRODUCT!!! I give these guys a perfect rating!!!"
