"Jake took down our old barn and removed two dead trees and relocated our water hydrant. He showed up a week before the job to give my husband advice on removing the electrical panel and get exact dimension for water hydrant. All went smooth in this 95 degree weather. Thanks Jake, you did a great job!"

"Herb was great. He also showed me how the water heater works and showed me how to turn on and off the main water supply and drain the sprinkler system to winterize. Very helpful. I would definitely hire him again."

"FEMA required that our commercial property grade be raised out of the new floodplain. I pulled together bids from numerous companies and got their opinion on how they would go about the project because of it being in a hard to reach area. Of all the bids, Buds was the most affordable, and his approach to handling the project was very straight forward and made the most sense. He got started right away and stayed on the project every day until it was complete, which didn't take long. He stuck to his quote and there were no surprises. The site has been surveyed and the work looks good down to every detail. Bud and his company BMG Services will always be my go-to service provider for any future projects."

Basement Waterproofing FAQs, answered by experts

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

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.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.
