"We had a small leak that only happened in severe rainstorms. Instead of diagnosing this problem the salesperson wa ted to sell us their complete system. They painted a picture of a poorly constructed basement with many problems. We resisted but finally agreed this was s mistake, because the only problem found after tearing up our basement was a dead sump pump and maybe extra weep holes could have been put in the crock. The original basement drainage system was correctly installed to code. Now our perfect basement floor has permanent scars and we are still fighting the concrete dust leftover from the project. The workers also damaged our vinyl siding and stained it with some type of solvent when cleaning areas that were marred during work. They are probably solve severe basement problems, but we were definitely “oversold”. We made a regrettable error in trusting their expertise."

"Very organized. As a working parent in a household with small children, Matrix’s process was very smooth. Once permits were approved, building moved according to the quoted timeline. We appreciated the app that kept homeowners in the loop about who would be on site on a given day and what was being done. Project oversight was very good. Our project manager was very responsive to our questions/concerns and a helpful go-between with the sub-contractors and inspectors."

Action Professional Window & Gutter Cleaning Service Inc. has served Madison and the Dane County area for over 30 years. We provide a variety of services for homeowners and businesses. We specialize in professional gutter cleaning and repair along with installing gutters covers that come with a 5-year warranty on parts AND LABOR. We clean siding and remove graffiti and grime from most any structure. We also pressure wash decks and fences. Let us also quote your snow removal needs too. Our top priority is providing full and complete customer satisfaction.

"This is an outstanding business and I would highly recommend them. I hired them several years ago to power wash my sister's huge house which was filthy on the outside. The team hand washed the whole house and worked so hard in 90 degree heat. They took a lot of pride in their work and did an outstanding job. The neighbors would walk by the house afterward and would not be able to put their hand on why it looked so good and when I told them it was because of the power wash that was done they wanted to know who did the work so they could make note of the company if they needed work done in the future. They have also done numerous gutter cleanings on my house and are reasonable priced, very professional, and do a very thorough job. The rep even made sure to get some of the dust from the shingles that had been in my gutter for a while scraped off so that it would not build up even further. I have never had a gutter company do that! I give this company my highest compliments. They are a pleasure to do business with."

Angie's List 2012, 2013 and 2014 Super Service Award winner. Servicing Illinois and Wisconsin. Co owners, Nick and Jonathan came together to start a company to serve both Wisconsin and Illinois, where they could utilize their 20 plus years experience assisting consumers with home improvement and development as well as water and air treatment. Their idea was to start a basement waterproofing company-Dry Otter Basement Waterproofing. Their goals are to provide a healthier home for their customers and develop long lasting business relationships but more importantly, friendships. Service area covered: Southern WI and Northern IL. Award wining.Additional email - [email protected].

"Nick and the Dry Otter crew do fantastic work. Everything from beginning to end was top notch. The estimate was true, the work was done well and on time, and the result of the project is perfect. I live on the East Side of Madison and have had water seeping into my basement for years now. Dry Otter trenched all the way around my basement and installed a sump pump. I've been thinking of doing this project for years and met with all of the local companies that do this, and I'm very glad that I picked Dry Otter for the project. I was definitely nervous about possibly having to rip out the existing basement stairs as part of the job, but these guys were able to preserve the existing stairs which saved me from a huge additional cost. I'd recommend anyone to strongly consider this company for a sump pump installation. They answered all of my questions after the job and even sent someone after the project was done to tighten a nut on the water meter that was slowly leaking. Now I'm turning half of my basement into a chill out zone for the kids and keeping the other half as a utility basement. Our house just became way better. Probably the best thing I can say about this crew is that they are honest business people that stand by their work. Expect a job done well, on time, and at a reasonable price."

Basement Waterproofing questions, answered by experts

Yes, you can over dehumidify your house. While you may prefer a dryer climate inside, the elimination of too much moisture in the air can lead to an extremely dry environment that can affect those with respiratory and skin issues. Strike a balance between eliminating excess moisture without making your home feel like a desert. Most modern thermostats show the humidity levels for guidance.

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.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.
