Groundworks Provides Professional Sioux City Foundation Repair, Basement Waterproofing, and More

Situated near the northwestern part of Iowa, Sioux City is located in both Woodbury and Plymouth counties, with the majority of the city being in Woodbury County. “Siouxland” refers to Sioux City and the surrounding areas of northwestern Iowa, northeastern Nebraska, and southeastern South Dakota and is a term of endearment amongst local residents.

Situated at the furthest upstream point of the Missouri River, Sioux City is both a travel destination as well as a peaceful area to live. With an average annual rainfall of nearly 26 inches, it is slightly below the national average. However, it’s the fact that more than 60 percent of that rain falls during the summer months when humidity levels often reach 90 percent, that’s the problem. Add in the annual 30 plus inches of snow, and it’s no wonder Sioux City homeowners deal with wet basements and crawl spaces nearly year-round.

The area’s soil differs depending on where you live in Woodbury or Plymouth County. Most soil is silt loam-based with varying levels of clay. The soil across the region also has different degrees of drainage, ranging from well-drained to poorly-drained. To sum it up, homeowners in Sioux City can experience several different types of foundation problems because the soil conditions differ considerably from area to area.

    I purchased a home in need of repairs. I looked around at different options to have a basement wall secured. I decided to go with Groundworks because the pricing was fair compared to other companies. Three men arrived, they worked very hard in the blistering cold to make sure the job was done correctly and professionally. Adriel explained in detail about the work being performed. They were on time when they said they would arrive, took great care of the house and did a fantastic job. After my experience with Adriel, I will recommend this company to friends and family. Thank you!!

    Nick Waldron and Mike Wrenn both helped to plan and install an expansion joint in my driveway. Service was exceptional. Nick was very detailed in his explanation and helped me understand the value of the expansion joint installation. Mike arrived on time and got straight to work. He was very professional and efficient. I was very happy with the whole process. Very professional and will recommend.

    We highly recommend Groundworks. Paul Winder was so professional and knowledgeable about what we needed to do to fix the foundation of our home. There were no pushy sales pitches and Paul was very honest and straight forward about what we needed and didn’t need. With the financing they have to offer it’s very affordable and we now have a peace of mind that our home will be solid for many years to come. Thank you Groundworks and Paul Winder.

    I had such a great experience with CLS. Dave, the owner personally came out to the house to give me a quote. I really like that the owner prefers to meet each client to fully understand the situation. The crew came out and was respectful and clean. They did a great job and the price was better than the other quotes I received. I highly recommend CLS.

    CLS was a great company to work with. Very professional and friendly. When the job was completed,they even took the time to show and explain to my elderly mom the work they had done. Thank you CLS! Shout out to Brenda as well for her help.

    I have been working with this company to repair several issues with our home after flooding. So far they have been amazing with answering all questions and responding to every email and phone call. Over the work is actually complete I will update my review.
