Below are just a few of the reviews and testimonials we've received from our valued customers across the Greater St. Louis area.

Chimney Cleaning & Inspection Reviews

"Mad Hatter was incredibly professional from start to finish. The technician arrived on time, explained everything he found during the Level II inspection, and gave us a clear written report. We had a crack in our flue liner that our home inspector missed entirely. They caught it before we had a house fire. Worth every penny!"

— Jennifer M., Chesterfield, MO

"I've used Mad Hatter for years for our annual chimney sweep. They always show up on time, lay down floor protection, and leave the house cleaner than they found it. Their 'no-mess guarantee' is real! Highly recommend to anyone in the O'Fallon or St. Charles area."

— Robert K., O'Fallon, MO

Air Duct Cleaning Reviews

"After a kitchen remodel, our ductwork was absolutely full of drywall dust. Mad Hatter's Caddy Vac truck system pulled out what looked like a bucket of debris from our vents. The difference in air quality was noticeable within days. My son's allergies have been much better since."

— Lisa T., Wentzville, MO

"Called Mad Hatter after noticing more dust than usual in our home. They sent a truck out within a week and the difference was remarkable. The tech was knowledgeable and explained what they were doing the entire time. Very impressed with the thoroughness of the service."

— David H., Ballwin, MO

Chimney Repair & Restoration Reviews

"Our chimney had been leaking for years and two other companies told us it needed a complete rebuild. Mad Hatter diagnosed the real issue — a crumbling crown and a cracked liner — and gave us a targeted fix at a fraction of what others quoted. The work is beautiful and comes with a transferable warranty."

— Sarah W., Kirkwood, MO

Real Estate Agent Reviews

"As a real estate agent in St. Louis, I've referred Mad Hatter to dozens of my clients over the past 10 years. They are fast, professional, and their written reports are lender-ready. When a chimney issue threatens to derail a deal, Mad Hatter always comes through."

— Mark D., RE/MAX Results, St. Charles County

"I can always count on Mad Hatter to prioritize my real estate clients when timing is critical. They communicate well, show up when they say they will, and the reports are clear enough for buyers, sellers, and lenders alike. They're my go-to chimney company for all my listings."

— Angela P., Keller Williams, O'Fallon, MO
