"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."

"My interaction with this company, represented by Gordon Rudd, was limited to a site visit only. Work that I thought might be needed turned out to be unnecessary. When I called the company, I reached Gordon directly, and he was able to stop by the next morning, right at the time we scheduled. He was very helpful in explaining what I was seeing. He didn't charge me anything for the very helpful visit."

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.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

In most cases, standard homeowners insurance policies cover water damage from sudden, accidental damage, like burst pipes and leaking appliances. However, water damage caused by flooding, groundwater seepage, or heavy rain is likely to be excluded from coverage. Check your policy to be sure, as some plans include opt-in flood insurance coverage. Certain companies also allow homeowners to add an optional water backup endorsement to a policy.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.
