Built on Grit, Backed by Heart in West Chicago, IL

Back in 1984, Kost Services started as a waterproofing business with a mission to keep basements dry, and that mission still drives us today. Over the years, we’ve grown into a trusted team serving both homes and businesses with reliable work across the board. With over 48 years of experience, we’ve stayed small on purpose.

Family-owned and locally rooted right here in West Chicago, IL, we care about the work we do and the people we do it for. Whether it’s concrete foundation contractors pouring strong slabs, concrete crack repair that holds up, or foundation repair contractors keeping buildings steady, we focus on what works best, not what costs the most.

Our crew also handles property maintenance services, detailed concrete restoration, and no-fuss bobcat services with that same hands-on, no-upsell approach. Alex and Bob, father and son, run things with honesty, practical fixes, and a shared love for building things the right way. We’re proud to serve neighbors, local businesses, and anyone who wants solid work done with zero runaround.

Thanks for stopping by. If you’re ready for quality without the sales pitch, let’s talk about your next project!
