"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."

"I couldn't be happier with the job LUX Foundation Solutions did to resolve my basement flooding issue. I requested a list of basement repair professional on Home Advisor and LUX Foundation Repair was the first of three to respond to the request. I scheduled an appointment for LUX to give me a quote on what it would take to resolve my basement flooding. Keagan arrived at the scheduled time and I described the flooding issue. It would require replacing the basement stairwell drain, sump pump and connecting pipe. We also discussed putting french drain and a larger pad at the top of the stairs to close a gap between the foundation and stairs that allowed water to channel into the stairwell. Keagan was upfront about how and when the job would be scheduled. I was contacted when the job was initially scheduled and kept informed on any changes as the start date. Adam and Ace arrived the date specified and went right to work. They were professional, knowledgeable and answered all questions I had. They were a pleasure to work with. I would recommend them to anyone looking for a foundation repair professional."

"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 waterproofed my basement and replaced my roof. They did a wonderful job! Insurance doesn't cover it so they made very affordable with their finance options they presented. I am so pleased! I will refer them to anyone that needs service. Thank you Best Buy!"

"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."

"Excellent. A breeze to schedule with, they texted a photo of the plumber and his name when he was on his way. Arrived on time and successfully unclogged basement drain, then proceeded to replace leaky kitchen faucet. I remodeled homes in a former life, but I did not want to pay for the parts/equipment as the majority of the cost of the work was covered under a home warranty. Therefore, I can't speak to the total cost or value, but I was satisfied by the work completed."

Basement Waterproofing questions, answered by experts

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.
