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."

"First there were a couple of delays due to COVID, the weather, and a truck broke down. The window guys were over 2 hours late. While excavating near the house, the workers “accidentally” broke our water main. This of course was our fault and cost us an additional $3000! Read your contract. There is a small clause about accidents not being their fault. Subsequently, we had no water for two days and a large plumbing bill from a plumber they sent. This may not be over."

"The person performing the service had to make several trips because one of the "new" parts turned out to be faulty. I found both Complete Protection and their local repair contractor to be both very responsive and totally professional at every stage of the repair process."

Septic Tanks questions, answered by experts

Your septic tank may be full or clogged if you notice household drains that are backed up, draining slowly, or gurgling; greener, lusher grass around the septic system; pooling water in your yard; or smelling sewage odors outdoors. You can contact a local septic tank pro to inspect your septic system and pump your tank.

Wells should be at least 100 feet deep for drinking water, but they may need to be deeper depending on the local geology, water quality, and your household’s water usage. Work with a qualified well drilling professional who can assess the appropriate depth for your well and test the water before drinking it.

The depth of your septic tank has nothing to do with its size. In fact, some septic tanks can even be installed above-ground! Like other sizes, a 1,000-gallon septic tank could be buried as shallow as 4 inches below the ground or as deep as 4 feet. It all depends on your specific property.

Some signs that a septic tank is full include wastewater or even sewage backing up into drains in the house, foul smells coming up through the drains or around the yard, pooling water in the yard, spongy soil underfoot around the septic tank, gurgling noises in the pipes, or grass that looks lusher or greener than normal without any new lawn care services.

Estimating what size well pump you need is challenging and often inaccurate, but a general rule of thumb is to take the number of fixtures—including water-consuming appliances—in your home and aim for that number in gallons per minute. That calculation method would allow for every fixture in your home to use about one gallon of water per minute. However, it’s best to leave the pump size determination to a professional technician, as they can ensure your pump is providing your home with sufficient water, especially during peak usage hours.
