"Based on the foundation being brick, there was not the option to add weeps. Additionally in the middle of February, I did not want to excavate the exterior. Therefore the waterproofing was done from the inside. Renew added a rigid board covering onto the foundation interior which will direct moisture downwards to the new drain tile system and now the basement is humidity and moisture free. Very pleasant folks to work with too."

"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."

Basement Waterproofing FAQs, answered by experts

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.

Having a trusted crawl space contractor is the key to great encapsulation. If you're not sure how to hire a crawl space pro, begin by asking your neighbors for referrals. Homes in your neighborhood will often have a similar foundation to your house, and personal recommendations are one of the best ways to find a contractor. Additionally, double-check that the contractor has experience with encapsulation as well as proof of their license and insurance.

Periodic inspections and addressing drainage issues prevent further damage.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.
