"Dave from Clifton Contracting/Exterior Waterproofing came out to diagnose a leak in our basement. He came out within 24 hours and quickly identified what was causing the problem (gutters). Although this is a job too small for Clifton Contracting/Exterior Waterproofing, I would not hesitate to contact them down the road if I ever had an issue they would be better suited for. Thanks!"

"Jeff came to give us cost estimate for fixing our basement leaking issue. He was one of most knowledgeable professional I ever meet during my initial move in to new house. He explained why it is leaking and what we can do about it in very detailed logical explanation with clear diagrams to assist my understanding. Jeff said to fix these issues if it still leaks than come back for further assessment. It was great help, and I can really work on source of this problem now. I will never use any other waterproofing company other than All Aspects Waterproofing, LLC."

"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!"

"I had Lux come out to do foundation work on our home, as well as exterior waterproofing. It was a large job, and as a first-time homeowner, I didn’t know what to expect. Miguel and his team were efficient and did a great job. They communicated very well, which I really appreciated, and the job was completed in about a week. They ran into a small snag during the work, but were able to locate the issue and fix it quickly. They were very flexible and understanding, even after the job when I had a few follow-up questions. I would definitely use them again!"

Basement Waterproofing FAQs, answered by experts

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

If foundation problems are not fixed, they will likely worsen over time, leading to more complex and expensive repairs. Neglecting a damaged foundation can cause a range of issues, including:

  • Structural Damage: Minor problems like small cracks can escalate into major structural issues. This can damage the house above the foundation and, in severe cases, lead to foundation walls caving in or a total collapse.

  • Water Damage and Pests: Moisture and water intrusion can cause flooding, mold growth, and pest infestations.

  • Health and Safety Risks: Mold can lead to poor indoor air quality and other health risks, while structural instability poses a significant safety hazard.

  • Reduced Home Efficiency: A compromised foundation can negatively impact your home's energy efficiency.

To avoid these escalating problems and costs, it's best to hire a foundation repair company to address any issues as soon as you become aware of them. The earlier problems are discovered and fixed, the lower the repair cost will likely be.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.
