"We had an internal house line leading to the sewer plugged on a Sunday. We couldn't run any water in the house without it coming out of the drain and into the basement. Based on all the positive reviews I read of KJM plumbing, I called Kurt and he was here within 20 minutes with his machine and cleared the clog, which took about an hour. Pleasant, polite man. The price was reasonable for a weekend emergency call. If I need a plumber again, he'll be the first one I'll call."

"Although I did not hire them, I was impressed by their honesty. He explained what the problem was, and told me that it could best be solved by a carpenter, as it was not a cement foundation problem as I thought it was. He also gave a price range of what he thought it would cost. Would hire if I had a problem."

"Central Wisconsin Excavating (CWE) did a fantastic job on our project. They built a solid, well-prepared foundation for our 80,000-bushel grain bin and graded our driveways perfectly to ensure water drains away from our buildings. Their attention to detail, quality of work, and professionalism really stood out. The site was left clean and properly finished, and everything was done right the first time. We’re extremely happy with the results and would highly recommend CWE to anyone needing excavation or site work done right."

"First, Bob [Provider Name Removed] took the time to explain all aspects of what is causing the mold in our crawl space. His explanation was consistent with the mold testing specialist/microbiologist we hired. The options for turning our crawl space into a mini basement were in-line with what our microbiologist said. The installation team was great to work with. They were very knowledgeable, professional, and respectful of our property. They cleaned up all the post project debris too. We are very happy with our fully enclosed crawl space that doubles as lock-and-key storage. We highly recommend the entire Basement Repair Specialists team."

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
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.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
