"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!"

"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."

"Once and done waterproofing helped me out with a small annoying leak Iâ  ve had around a pipe. The owner called me right away, came out the next day for an estimate, and fixed the leak the day after. His crew is friendly and courteous and hard working. Explained every step they weâ  re doing. Did such a great job, I had the bury some drain pipes and install a rain water reservoir. Very reasonable pricing and veteranâ  s discount."

"We contacted JES due to water flooding in our basement during heavy rain. Jason Gamse was on time, took the time to thoroughly inspect our basement and explain the reasons of our issue. He presented our options and was able to give us a pricing on the spot. We recommend Jason to assess any basement foundation and waterproofing project."

"Fantastic! Dan (of RPD CORP/Archer Contractors) came out to consult with me about my leaky basement and cracked walls. Dan was knowledgeable, and his understanding of drainage and structural problems gave me comfort in knowing that I have the right group for the project. They installed a drainage system to control storm water, graded the land, and repaired my foundation. His crew came out within 1 week, on schedule, and completed my project in 3 days. They were professional, efficient and exercised care. It'��s been a year since the work was completed and the basement is 100% dry."

"We had a great experience hiring '58 Foundations to waterproof our basement! Lon was our salesperson, and he came and explained the work that would be necessary to ensure that water would never flood our basement again. We appreciated him taking the time to explain how the whole process worked, and providing us with the option to finance the project to make it affordable for us. We had Brett Boyles and his crew, John and Clarence, come to do the work, and they did a fantastic job! Brett even came to show us the progress in the middle of the project and explained every detail of the work that was being done. He was very professional and we appreciated how he gave us peace of mind about everything once the project was completed. I would highly recommend '58 Foundations for anything basement-related. We appreciate your business - thank you!"

Basement Waterproofing FAQs, answered by experts

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

The first step to preventing foundation cracks is to repair any current ones. When one crack forms, it becomes more likely that a second crack will follow. A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.

Regular inspections, maintaining proper grading around the foundation, and keeping gutters clear are advisable. Vapor barriers and sealants may need checking for wear after several years.
