Swainco = Integrity. I had Mike Smith come out to review the home we just purchased. another foundation company in Indiana had given me a quote for $50K for work in 4 areas. Mike looked at the "concerned" areas and saw no legitimate issues. We shook hands and I will call him when/if we have real issues.

We have had SwainCo encapsulate and install a crawlspace drain system under two houses. They are professional, courteous, reliable, and their services are unmatched. The team was very knowledgeable and took pictures of the work, step by step. We couldn’t be more pleased and highly recommend SwainCo!

Paul Grissom

I wanted to share how great this company has been for me as a new homeowner. I had Mike come out for an estimate. He took his time making sure I understood what the problem was and what could be done. He came prepared with an information packet I could look through and followed up with a quote a few days later. The pricing was lower than other quotes I've gotten but more than that, I felt comfortable with the company as a whole.

Great work and great crew! Gave SwainCo a call to help bury a downspout drain and discharge out to the middle of my front yard. Kendrick took my call at their office, answered some questions I had, and was very helpful. Kendrick and two other teammates came out right on time on the day we scheduled. The three of them worked really well together and knocked the project out in only half a day. We’ve since had rain on numerous occasions, and all is working smoothly. It’s been a relief to finally have that drainage routed properly!

I called SwainCo to evaluate my leaking crawl space. 2 other companies gave me an estimate to dig up the crawl space which was vey expensive. Mike Smith from SwainCo told me to just relocate my HVAC lines above grade and patch the holes and it would solve the problem. He was right. No further leaking, the crawl space is dry. He was very professional and honest. He could have easily recommended digging up the crawl space but didn't. I will use them if I ever have a problem in the future.Great company.
