"We had a master bathroom completely gutted and remodeled. Sean designed the layout and Jason was the project manager. We were very impressed with the level of quality in everything from the initial design to the final result. The minor issues that did come up were resolved very thoroughly. Would highly recommend this company to anyone considering a major remodel project."

"Workers wore masks and kept a good distance when interacting with us. I am thrilled with the concrete leveling. If the driveway sinks again within 3 years they will fix it for free. Nice folks and excellent results."

"I helped my daughter with this crawlspace encapsulation work on her house. I solicited 3 quotes and it was an easy choice to go with Basement Waterproofing Nationwide. From the initial inspection and quote with Tim, the financing and finally the work with Will and his crew, everything went well. They completed the job to my expectations, answered all my questions and kept me informed all along the way. They actually finished the job in 3 days instead of 4. I highly recommend giving them a chance."

"We originally contacted JES because there was a persistent moldy smell on the lower level of our house. Chris Yi did our estimate and was extremely thorough in explaining what was causing the smellâ providing pictures and walking us through our options on getting rid of the mold growing on the supports under our house due to the high levels of humidity in the area we live in. After assessing the options, we decided to go with encapsulation with a dehumidifier, which Chris said was our best option for the above stated reasons. Chris clearly knew his stuff, which reassured us that we were doing the best thing for our home. When it came time for the work to be done, the crew that arrived was extremely professional. Emilio Sanches, Juan Mata, and Angel Mata worked expeditiously, but the level of craftsmanship was top notch. The moldy smell is gone and we have confidence that the mold will not return. JES was the total package for our crawlspace needs.Â"

"The crawlspace in our recently purchased house was a mess—full of water, mold, and deteriorated insulation. NV gave us a competitive price, on par with the other bids we got, and their bid seemed more comprehensive than some of the others. Jaime did an excellent job explaining everything to me and talking me through any questions we had. Once the work began, Manny and the rest of the guys did a great job—they were on site promptly each day and were clearly working hard over the three days of the project. Manny was very communicative and easy to work with and even went out of his way to help us with some extra items in the yard. The crawlspace looks awesome now—clean and dry! Thanks again to the NV Waterproofing team for all their hard work and helping us clean up a rough part of the house!"

"Dan understood our problem did not need trenches and pumps inside our home. Our hill-side home didn't need a sump-pump internal system - drains run to daylight. His gang hand-dug an external trench, laid in perforated drain pipe and silt barriers and drainage gravel. They repaired cracks in the foundation, dried it, applied a drying rubbery material, then installed a dimpled drainage barrier cloth. They graded the earth around the house to aid rainwater runoff. Even re-planted my hasta garden. 2 days, start to finish. We are confident this will succeed."
