"They fixed two leaking cracks in the basement exteriorly in May 2019. Also, they regraded the patio so that the rain water runs away from the house. I am happy with their works. I am glad my basement is dry now. Thank you."

"Angelo did a great job during the estimate process. Ends up that we didn’t need the work that we thought we needed and he was honest about that. Still provided me really great advice on what was needed so that I could rectify the issue. If I ever need waterproofing done, I’ll definitely be calling them first."

"Alex from Lux, gave me very helpful advice and he concluded that his company’s services were not warented. Trustworthy, honest advice, and he answered all my questions thoroughly with visual and verbal explaination. Lux is a company I would recommend and use in the future. In my personal opinion, Alex saved me $10-30k in waterproofing. He said that I did not have a moisture issue in my basement and he gave me 3 things I could do to make my basement environment safe and sound for the future. A different contractor came in and gave me a free estimate to put a sump pump in for $7k and then I’d need to finish my basement for an estimate of $20k. Alex from Lux, said I had a dry foundation and that my mold on my vinyl was likely a cause from a leak years ago from my washer or my dishwasher a level above. I truly felt that Alex was truthful, helpful and Honest. Go with Lux if you seek an honest opinion and company."

"I was very impressed with the whole experience with NV Waterproofing, from the estimate to the completion of the work. I had mold growing on a basement wall and a perpetual musty smell in the basement. Cristian came out to do the estimate. He did a full walk around outside the house and then did a thorough inspection of the basement. It was good to see that he used a moisture meter when doing the inspection. It's amazing that out of four companies that did estimates, NV Waterproofing and one other were the only ones to bring that tool. He looked at a waterproofing system that had been installed right before I moved in and explained what was wrong with it and then explained how it could be fixed. He was patient and explained everything. I appreciated that he did not put any pressure on us to sign anything before he left. After getting the estimate, I had questions and called the office t get answers. The office staff was great, answering what they could and forwarding the rest to Cristian who answered them promptly. Between scheduling the work and the work beginning, the Covid crisis hit. NV Waterproofing was great with working with us to explain our options of continuing with the work or rescheduling. I decided to go ahead with the job. The crew that performed the work was very professional. All had masks, all kept a good distance, and they did a great job of keeping the place clean. The foreman was easy to contact and promptly answered any questions I had during the job. All in all they were great. Including coming back promptly to finish off a final piece of work that had gotten overlooked."

"Best Buy's Regional Manager(Dan Mayo) came out in a timely manner to give us a quote to not only waterproof our basement but he also inspected our crawl space that unbeknownst to us had leakage also and had built up mould. His quote was most reasonable in comparison to other companies and he adjusted his work schedule to accommodate our travel schedule. We were leaving in two days and he had his crew come the day before we left and they completed the work that day. The crew itself was impressive in their work ethic as they labored almost non-stop from 9 a.m. to 7 p.m. What a relief it was for us to have this work completed before we left for two weeks.. Dan's follow up was extraordinary as he showed a willingness to fix anything that may have been overlooked."

"They did an excellent job of waterproofing our foundation, burying downspouts, and replacing a patio to guarantee drainage away from the house. Most of our interaction was with the crew foreman. He spoke good English, showed attention to detail, and did a careful, professional job even when the weather got so hot we found ourselves urging the crew to take more breaks. They were not the cheapest bid, but worth it for the skilled workmanship. This is the second project we have hired them to do, and I would recommend them for any work where drainage is important."

"I would recommend this company immediately for anyone looking to have insulation work done. Our house was extremely drafty and bills for heating and cooling were high- after the initial consult , I was sold and hired them. The job was no small task but I was very impressed with the teams professionalism, attention to detail and their very special attention to keeping the place in some order in between the days of the project. I can't say anything negative about any part of the experience- even the ceiling repair team was amazing. Thank you John, Scott and team!"

"Lux foundation repair did a wonderful job at my home. I have 4 pipes coming into my home that had deteriorating seals around the pipe. The seals had deteriorated to the point that I had a large plastic box under the pipes so that after every rain I would collect the water that otherwise would have destroyed our finished basement. After small storms, I would collect a couple gallons, after very large storms, I would collect over 8 gallons of water in the box. I spoke to one contractor who suggested excavating the outside of the home. No small task since the pipes enter about 6’ below grade and it would have involved removing several established plants. I was surprised with the estimator from Lux informed me that they could solve the problem from inside the home. I was surprised that the estimator was very confident that he could not only fix the problem, but guarantee that it would fix the problem. The work team arrived on time, quickly did their work and left. When the next storm arrived, I checked the box….no water at all. Was it painless? Yes. Was it worth the money? Yes."

Basement Waterproofing FAQs, answered by experts

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

A crawl space encapsulation isn’t always necessary, but it’s a wise choice, especially if you live in an area that sees a lot of precipitation. Sealing a crawl space not only reduces damage caused by moisture, mold, and pests, but it also increases your home’s value. It can also save you money by reducing energy bills and avoiding costly repairs for structural or foundation damage.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.
