"I wish I could give Innovative Basement Authority a negative rating. Run away from this company as fast as you can. Beware- they are changing their name to Ground Works. Probably because of all the negative reviews. We paid a substantial amount of money to install one of their basement systems after having water problems. The initial sales guy was a very high-pressure seller, trying to get us to sign a contract the same day he came out. Fast forward a year. They told us they needed to come out for an inspection. The sales guy ?found? $40,000 work of additional work that was ?urgent?. He used scare-tactics and tried to convince us we needed to sign on the dotted line immediately. Because of course mold is going to make my family sick. It seemed sketchy to me, but I was able to get the guy to leave without us signing that day. I immediately called our trusted home inspector, and he said the sales guy was trying to sell us things we did not need. He also said he had talked to others"

Basement Leak Repair questions, answered by experts

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites
