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."

FAQs for house leveling projects in Cortland, IL

One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.

Typically, it’s more affordable to buy an existing home than it is to build a new one. New construction loan interest rates tend to be higher than interest rates for traditional mortgages. Additionally, the cost of materials is likely higher when building a new home than it was when an existing home was built (unless it’s a very new one). You’re also paying for all new appliances, finishes, permits, inspections, and connections for water, gas, and electricity. 

The most common first signs of foundation issues include: 

  • Cracks in the foundation walls that grow

  • Signs of moisture or water leaking through cracks in the foundation

  • Standing water in the basement

  • Sagging floors or walls

  • Cracked walls in upper floors

  • Doors and windows that don’t close properly anymore

Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.

If you’re noticing signs of foundation issues, the first step to fixing a foundation problem is to hire a foundation repair inspector. They will determine the problem, the cause, and the severity before recommending a course of action to repair the foundation. The method for fixing foundation problems depends on the problem and what options are available. A few possible solutions include:

  • Epoxy injections

  • Mudjacking

  • Piers made of steel or concrete

  • Jacks 

  • Hydraulic piers

  • Carbon or steel reinforcement strips

  • Waterproofing materials
