"They work was great. The basement has been dry ever since. Their price was the best of the estimates I received. The service was great and the salesman was great. They didn't make any stains or drop anything. The gentleman came out the same day I called him."

"Basement Waterproofing Nationwide did excellent work in a timely and proffessional manner for a reasonable and appropriate fee. They said they would complete the work in 1-2 days and were done in one day. They were very careful and left things neater than they were before they came. We have used them before with great success and would use them again. So far, the problem we had, water in our basement, has not recurred, and our basement is bone dry. Tnank you Basement Waterproofing Nationwide."

"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."

"We moved into new house and quickly found out the basement had major water issues due to years of neglect (including a clogged and poorly installed English drain from years ago, and a sump pump that while it worked, never pumped water.). Given the investment we made in buying the house, we wanted to make sure we left no doubt in our mind that we were fixing it for the long haul so we could use the basement without worry of mold/mildew for our kids. We had NV Waterproofing install perimeter wide gutter guards, and a new sump pump system and drainage pipes. As soon as the work was done we got rain, and for the first time in the 4 months since we have lived here I saw the water that otherwise would be in our basement actually in the rear of our backyard by the discharge pipe. We have had a few more rains and even one snow and there is nothing better to look at then when I see the water that is coming out of the discharge pipe that I know otherwise would be pooling in my basement and cynderblocks walls, and how that was the case for many years before we moved in. Also, the team that did the work was extremely professional. We have 3 kids and pets and the team was extremely courteous. We tried to stay out of their way during the week they were doing the work, however there were times when we couldn't and the team was extremely courteous and professional. The team lead did an amazing job of explaining to me the work he was going to do, showing me updates, and then afterwards explaining in detail what was done, why it was done, and things for me to look for for in the future. I would highly recommend NV Waterproofing to others based on my experience with them. They did high quality work and were extremely professional."

"We had a basement waterproofing issue. Shopped around a couple of companies. With the best rating on google, and with good reason, Best Buy Waterproofing was our choice. Rob was knowledgeable, diligent, patient and open towards our questions and concerns. Best experience I had with any company rep to date. He came out twice to our place (once the first time to look at the issue, second before he took the work to make sure we all are on the same page.) And then he was there before the work was started to make sure all of us were on the same page. The crew that came out (Darwin, Juan, Raul, Hammie, Chilo) were very careful about their work, respectful, and meticulous. They plastic sealed the work area to prevent dirt, and broom cleaned the area after they were done. Even after the work was done and the transaction was completed, Rob came out to check the work and to make sure it was up to his standard. He olso brought with him the mold treatment up on my request and took care of that as well. Thank you Rob! I highly recommended Best Buy."

"The crew arrived on time. They all went right to work. I hired Tru Integrity because the representative who came to my house to see what had to be done to fix the water problem explained, in language I could understand, the steps involved. Of course I cannot judge the work until we have rain. When the job was completed the basement, yard and driveway were cleaned."

Basement Waterproofing questions, answered by experts

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.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

Generally, moisture barrier padding costs $0.75 to $1.50 per square foot, varying by brand and mix. That’s a lot more than standard padding, which runs $0.25 to $0.90 per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.
