About Cornerstone
Cornerstone Foundation & Waterproofing was built from the ground up right here in our community. As a family-owned business, we know how important your home is β it's not just a structure, it's where life happens. With years of experience solving foundation and water issues, we take pride in honest work, fair pricing, and treating every customer like family. We're not a big corporate company β we're your neighbors, and we're here to serve Southern Indiana and Louisville with care you can trust.
The Family Behind Cornerstone
Nicholas, his family, and the crew.

Cornerstone is run the way Nicholas and his wife wanted their family business to work: on-site ownership, a small tight crew, and customers treated like neighbors because most of them are.
βWe don't just repair foundations β we rebuild trust. Every customer, every job, is a chance to do something excellent and leave a home better than we found it.β
This business is more than a trade β it's a calling to serve. Every homeowner who calls us is placing real trust in us, and that trust deserves honesty, quality workmanship, and respect, even when no one is watching.
We're not chasing volume. We're building a reputation job by job, handshake by handshake, in communities where we live and work. When we show up to your home, we bring the same standard we'd want someone to bring to ours.
Nicholas founded Cornerstone in 2020 after 20+ years working in the foundation and waterproofing industry. He built it on a simple principle: give homeowners a straight answer, do excellent work, and treat every property like it matters β because it does.
The company is family-owned and family-operated, serving Jeffersonville, New Albany, Clarksville, Sellersburg, Charlestown, and the surrounding Southern Indiana region.
The Team
Who You're Working With
Nicholas Applegate
Owner & Lead Technician
Nicholas has over 24 years of experience in foundation repair and waterproofing β and he still works every job alongside his crew. You won't find him managing from the office while someone else figures it out. He's in the crawl space, in the basement, on the job site. Customers notice, and they mention it in nearly every review.
What We Stand On
Our Commitments to Every Customer
These aren't slogans β they're the standards we hold ourselves to on every job.
Honest Guidance
We tell you exactly what's wrong and exactly what you need β nothing more. If it's minor, we'll say so. If another company exaggerated, we'll say that too.
Quality Workmanship
No shortcuts, no patches over problems. We fix the real cause, do the work right the first time, and leave a job we're proud to put our name on.
Respect for Your Home
Punctual, clean, communicative, and careful. We treat every property the same way we'd want someone treating ours β because this is someone's home, not a job number.
Service With Purpose
We're here to help people in stressful moments. Being the company you're grateful you called β that's the standard we hold ourselves to on every estimate and every job.
