"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."

"This was a huge job. A complete basement waterproofing - new internal drains installed and two new sump pumps installed. The guys were great - came on time worked hard all day and cleaned up after themselves. The only negative was at the completion of work when it was time to pay the amount was less than what was originally quoted. I told the guy that and he insisted that it was what he had. I even showed him the quote on paper. I paid it - glad it was less, but a few days later got a call from the office telling me I needed to pay another $1600 (the difference between the original quoted price and at the time of service price) I told her what the guy told me and she got a little rude saying "well you knew what the quoted price was" - yeah I DID know and was prepared to pay but after install HER guy insisted it was the price he had. I wasn't trying to get out of paying but the confusion on how much it costs was with the people working there. I didn't appreciate her attitude as if I was trying to skimp out of paying. Nevertheless, I ended up with this additional payment. However, the work is supposed to be guaranteed for life. No complaints there."

"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!"

"I had a bad water issue in my basement and instead of digging up the concrete floor and installing french drains, Humberto addressed the issue of water getting in in the first place. He sealed and refinished our driveway and waterproofed the area where driveway met the foundation of the house. Also installed sump pump in landing of basement stairs and installed drains in the window wells. He was very responsive and wonderful to work with. I highly recommend!"

"I highly recommend this waterproofing company! From my very first contact with them—even before I hired them—they were kind, patient, and extremely helpful. My basement was flooding, and the initial person I spoke with immediately made me feel relieved and confident that I was in good hands. The entire team provided excellent service from start to finish. I’m very happy with the work they did! They were so neat with my house making sure none of the floors got messed up. They even steeped the porch outside when they were done. The test not a drop of water anywhere. Thank you so much. I forgot names. The lady in the office is wondering as well. Prompted!!!! They didn’t take are to give an estimate like other companies. 🙌🙌👍👍💪"

"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."

Basement Waterproofing FAQs, answered by experts

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

A crawl space is an area under the house that provides access to plumbing, electrical, heating ducts, and other HVAC units. Its purpose is to create a buffer between the ground and the living area, helping with ventilation, moisture control, and access for maintenance or repairs. Crawl spaces are most often seen in houses in North America which are built on concrete foundations versus other parts of the world where buildings are constructed differently.
