"Where do I begin with this review. I stopped at the West Allis Farmers Market AND the West Allis Car Show where the booth was busy and I waited for a chance to enter for the yeti cooler drawing and an inspection after the flood this summer. The conversations that were happening around the booth from what seemed like employees or friends of employees is what caused me to walk away TWICE. I am not sure what kind of company you'd like to be known for but the conversations I heard were appalling to say the least. But I went to the review page and saw comments from the General Manager when a potential customer had voiced concerns - this is the example your employees follow. They are a product of this type of environment. Sounds like you need to get a handle on your staff from the front desk all the way up to your GM. Sleeping around, moving from department to department. Might want to get a handle on that before you have an STD outbreak on your hands. Id hate to be the significant other or spouse of an employee that works here. And after reading the reviews I'd hate to be a paying customer bullied by a company. I also have a "no soliciting" sign and what was left in my door. Soliciting. But reading reviews I have seen this multiple times being expressed. Education stated it was provided but seems the GM fell short here too."

Basement Leak Repair questions, 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.

The frequency with which a French drain clogs depends on various factors, such as the amount of debris that enters the pipe, the quality of the French drain installation, the type of grate and filter used, and how often it is maintained. That’s why it’s recommended to clean your French drain at least once a year, whether it is clogged or not. This can prevent clogs and increase the lifespan of your drain.

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.

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.  

The best basement waterproofing method depends on the issue you’re trying to solve. For example, if you have standing water on your basement floor, a floor drain or sump pump might be your best solution. Or, if you have standing water around your foundation, installing a drainage system that protects your basement and foundation might be better.
