We Know Southern Indiana

Clay-heavy soil, high water tables, aging homes β€” we've been dealing with these conditions for over two decades.

Local. Not a Franchise.

We live here, too. Our reputation is local. When we finish a job, we'll likely see you at the grocery store.

We charge for what the job requires, not for what we can add on. If you don't need it, we won't suggest it.

Common Questions

Frequently Asked

Why hire a local contractor instead of a national franchise?+
Three reasons, all practical. Response time β€” we live here, we can be onsite in days, not weeks. Accountability β€” a national franchise can ship you off to a call center; we answer the phone. And local knowledge β€” clay soils, Ohio River water table, and freeze-thaw cycles behave a specific way in this region, and the right repair reflects that.
Is Cornerstone licensed and insured?+
Yes. Cornerstone Foundation and Waterproofing LLC is a fully licensed and insured Indiana-registered contractor. We can provide proof of insurance on request and our license number is included in every written quote.
What warranty do you offer?+
Basement waterproofing work carries a transferable lifetime warranty β€” it stays with the home when you sell, which is specifically valuable during real estate transactions. Foundation repair and structural work carry manufacturer and workmanship warranties that are outlined in writing on your quote before any work begins.
How long has Cornerstone been in business?+
Cornerstone Foundation and Waterproofing LLC has been in business since 2020, but the owner Nicholas Applegate brings 24+ years of hands-on foundation and construction experience that predates the company. The business is family-owned and based in Jeffersonville, Indiana.
What if something goes wrong after the job is done?+
Call us. Our warranty is not decorative β€” if something covered by the warranty is not behaving the way we said it would, we come back out, diagnose it, and make it right. This is how we have earned a 5.0 Google rating and almost all of our work through referrals.
