"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"We experienced water in our basement for the first time due to our sump pump failing. We went to Home Advisor and found AUS. They responded quickly late in the evening and a few hours later we had a new sump pump installed and water quickly began recede from our basement. Our tech was amazing and very professional. He left our home just before midnight and had more homes to do. We were very pleased with the quality and timeliness of the repair and would definitely recommend AUS again."

"We were pleased with the customer service, skill set and careful attention provided by Indiana Foundation during last week's waterproofing work on our basement. Josh Solomon and Noah Salisbury were diligent in their attention to our questions and concerns, going the extra mile to ensure a quality installation that met our needs. Our basement is already drier and we hope to build it out for a play/rec room soon."

"We had a different person who came out before them who was horrible and then I tried Crawlspace/Basement Waterproofing Solution because they were reasonably priced and they worked with me on scheduling their time so that they would be there when the electrician are there. They worked together with the electricians and were all done. They were wonderful. It was an all-day project but everybody worked together. Everybody showed up, everybody cooperated, and it was all done in one day with a big job. They were very good with the whole thing. The price was really good deal and all they have to do is seal from the outside to the inside. The biggest thing for us is that, they were here when everybody is here to do one thing. They are really good and we only had one problem but it was all filled up. This company gave exactly what we needed, showed up when they are supposed to, and did a great job. It was perfect. I would recommend right away to anybody before anybody else.  We were very impressed with them."

"Our house had a water damage that ruined much of the drywall and floor on the first floor and the basement. For such a big repair job, I carefully looked up the reviews and recommendations from Angie's list and talked to 3 contractors that have the highest ratings. AOM was one of the three. David, the owner of AOM, quickly came to our house, assessed the damage, explained to me what need to be done, showed great empathy to our loss and current situation (having to stay in hotel waiting to go back to our house), and put a very competitive bid (about 2/3 the bid of another contractor). We picked them and signed the contract. AOM uses Trello, a cloud-based project tracking system that software companies often use, to effectively and promptly communicate task description and updates to all workers and house owners. AOM workers are professional, hard working, and friendly. For such a big project, expectedly there were some hiccups and AOM had to juggle ours with their other on-going projects. David kindly explained to me various aspects of the repair work and promptly fixed any faults that we identified. I became to completely trust David's professional skill and that he would treat our house like his. Several nights and weekends David came to work late so that we could move back to normal life as soon as possible. In the end, we are very happy with our remodeled house. I sincerely recommend David and AOM for any house remodeling and restoration job."

Basement Waterproofing FAQs, answered by experts

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.
