"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!"

"We are the 2nd owners of a 15 year old home. Don't know why the original owner/builder did not put a sump pump in the basement, as it would have been a cheaper option in the end. If you are building a new home with a basement, put a sump pump in, don't scrimp on what is a very valuable insurance policy. After looking at a handful of other companies to retrofit a sump pump in our cellar, we picked All Aspects Waterproofing, LLC. They did a great job! Very high quality work, and outstanding service. They did a great job! We enthusiastically recommend All Aspects Waterproofing to any homeowner!"

"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."

"Exceeded my expectation with waterproofing my entire basement + window wells. These guys are the real deal! I worked with Rob and I was educated and all my concerns were addressed. They do it right by you, the contract missed a window well and they were able to addressed that without having to go through a whole new quote/contract. Helped move some furniture around and left the place clean."

"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 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 questions, answered by experts

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all.
