“Words cannot express our satisfaction with you personally, as well as your workers. The “total” effort to waterproof our home was magnificent! Please allow us to reference you to anyone!”

  • Your good character was evident the moment we met you, You were also courteous and professional in your conversations with us.
  • You communicated with us via email, phone, U.S. Mail, and home visits, as promised.
  • Your BBB rating was excellent.
  • You analyzed all aspects of the water problem: the roof, gutters, terrain, foundations, flooring, etc.
  • You spent many man hours doing physical inspections, and drilling, before submitting the proposal – you wanted to be accurate, and we appreciate that.
  • Your being bilingual helped to avoid any misunderstanding with your workers.
  • You worked hard, and asked nothing of your employees that you wouldn’t do yourself.
  • You worked long hours, including on the weekend.
  • Your being trustworthy – (a large crew in an empty home for 2 days) – was a great comfort to us.
  • You and your team showed attention to keeping our home clean in the work area and access points. Several tons of debris and supplies moved in and out (up and down stairs) during the repair process. Your team used: drop clothes, an air scrubber, plastic door covers, vacuum, wipes, etc.
  • You presented us a very, very, fair price.
  • You adjusted the schedule and minimum price very fairly for unforeseen problems.
  • We look forward to you scheduling us for the cleaning of the exterior of our gutters.

Thanks for your excellent work. I know you are a man of your word and will finish the EZ Breath installation once the sheetrock is done. I did not see the need to hold the $100 as you suggested. I look forward to hearing from you soon about the estimate for re-finishing the sheetrock, and the estimate for laying down the vinyl flooring. Thanks again!

Joe Soster and his crew installed a basement waterproofing system and a sump pump in my home. The quality of work was simply awesome; the crew respected our home, worked hard, and produced a great final product. The price was very reasonable. I am very satisfied!

I wish to thank you and your men for an excellent job!

Thank you and your crew for working on the various parts of my house. You’ve helped me out in more ways than you could know, taking away much of the burden. I’m appreciative of the fact that you billed my only for the men’s time on the last day.

We are very thankful to Joe Soster for fixing our basement water problems. Joe assessed the problems and created an out-of-the-box solution that worked perfectly for our unique needs. He and his team went above and beyond by fixing downspout issues outside of our house. Joe was professional, thorough and worked within our tight budget and time constraints.

Waterproofing One did an amazing job installing a French drain, water well, removing an old sump pump that wasn’t to code and installing a new one. Every time it would rain we would have water in our basement. After Waterproofing One came out we never saw water! We’ve had some extremely intense rain the past few months and not one drop of water in the basement! They were professional, reasonably priced, and were done in one day.

The project was top notch. Not only did they consistently show up on time, but they finished the project early. Final project turned out great!

Joe and his crew did a great job waterproofing our basement. Before Joe and his crew waterproofed our basement, the basement was damp, smelly, and was prone to standing water. Joe and his crew removed all water damaged interior walls, put a French drain around the perimeter of the basement, installed a Sump pump, install new downspouts, cleaned and graveled all the window wells. He and his crew did all this work in about three days. The best part of the work that Joe and his crew did is that the basement is now DRY. Even after several heavy rain storms, the basement is dry. I recommend Joe and his crew for anyone who has a basement that is damp musty, and prone to standing water. They will get the work done quickly and when they’re finished the basement will be dry. Thank you, Joe, for your great work and your reasonable price.

We had our basement waterproofed (drainage system and walls). We also had glass block windows installed. They look great. Couldn’t be happier with their work. Would definitely recommend them.

They had to return to complete the job. I couldn’t wait til it rained so I could see if everything was done correctly. It was and my basement is still dry, not musty or moldy or anything. I am quite happy with the work.

Extremely clean; timely, pleasant workers. Andy (spvr) was helpful and Javier (installer) was hard worker with good alternative ideas for repairing the water leaks into the bsmt.

The showed up the first day on time and explained what was going to happen. The used plastic tarp to protect the first floor of the house from dirt and dust, put tarp down on the floor to protect the hardwood floors. They removed stone and dirt from the basement, laid a new footer and concrete block wall. Then filled in with concrete and smoothed over. The repaired the other two walls, filled in the floor with gravel. Also, removed old insulation, replaced it with new and installed a moisture barrier. These guys were professional, knew exactly what they were doing, protected the house from dust/dirt, cleaned up every day before they left. The job they did was physically demanding, as they had to cart materials in and out of the house by bucket, as there was no outside entry into the basement. I would HIGHLY recommend them.

They went beyond what they said they would do. Always on time and cleaned up afterwards. No more water in the basement!

From the first phone call to the completed project was about two weeks. None of the other estimates came close. They always showed up on time and cleaned up before they left. We have no basement entry, so all work had to go through our living room to get to the basement, but they kept it clean. Best of all, no water in our basement any longer, even after a few soaking rains. Very easy to work with and you have direct contact with the contractor, not with an office. Good experience.

They did a terrific job and some of the worksite was left dusty, but what counted is what they did about it… they came back and made it right and re cleaned the entire space in my basement. I am also having them do my gutters. They came back on the weekend to re-seal my window and just nice to see a local company in the area do good work and care about their customers’ satisfaction.

Joe Soster & Co. never disappoint. I have worked with Joe, Andy and the crew on numerous jobs and my clients are always pleased. They do what they commit to even when the unexpected occurs. And their craftsmanship and price are excellent and back it up with a lifetime warranty! I highly recommend Waterproofing One to anyone looking to get it done right.

They installed my exterior french drain and I will be using them for my siding and gutters.
