"We had previously hired someone to waterproof our basement but it severely failed. Once AFS came and accessed the crawl space, they implemented a new system. Our crawl space is amazing now and the team Quadarrius, Jovian, and Dallas were professional, informative, and proficient! Colt my representative walked me through everything before during and after! I love this company and recommend their services to anyonet!"

"We were in the middle of moving, we were selling the house that we were in and closing on a new home and there was some moisture found in the basement. This owner was great! We had called other different companies and because of our limited time frame (closing on a house), he was the only one that could come out right away. He treated the walls and waterproofed the lower level wall in the house. By far he was the most affordable company we quoted and he was a very hard work. Honest guy. He gave us a sense that he would not pull one over on you like most companies."

"Calvin was super helpful in getting us exactly what we needed for our 1903 home. Full crawlspace encapsulation and a repair of a sagging section of the house that was overloaded with a floated concrete floor. He easily could have oversold us on expensive repairs that were unnecessary but he was honest and up front with our issues and reassured us that our foundation was in really good condition for the age of the house. The crew doing the work showed up when they said they would and left the place clean. Highly recommend these guys to get the job done right!"

"I was upstairs and I heard a lot of noise and the house started shaking. There were cracks inside the house. I asked what happened and they said the jack slipped. After that they said everything was good, looked level. They were supposed to redo my front steps by tearing the whole thing down and reconstructing it, but they talked me into just letting them fill in the area under the stairs with concrete and they did a sloppy job as fast as he could so they could get paid and be done with the projects. Now water gets under those area he filled and goes into the foundation. The hand railing is also not secured well to the concrete and I requested the redo that. I realized after they were done that the house was not level by the garage door. They hired a person to install a new door and he had real trouble getting the old one taken down and then had trouble with the install as well. The crew did not clean up after themselves at all. My niece and I spent 5 hours cleaning up all the bricks and concrete. One day they left my front door open and my house was filled with concrete dust everywhere. I called them several times to ask them to come out and look at the spot above the garage that was still sagging. They would tell me they were going to come out once they get more work in the area, but never came. A few months ago he said I never complained or called him. He still hasn't been out here to look at the house and I don't think he's planning on it. The last time we talked he said he was going to call before he came out but I haven't heard from him. I was responsible for repairing the drywall crack on the interior, but was assured there wouldn't be many, however, there are huge cracks all over the house."

"Bought this in the spring to use before burning in the fall/winter.  Ended up moving in December and did not use it.
I'm wasn't sure how to score a company I didn't use (and not reviewing isn't really an option), so I just picked a score consistent with the average rating.

Basement Waterproofing questions, answered by experts

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.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

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.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.
