Trusted by Hundreds of St. Louis Families

⭐⭐⭐⭐⭐ Chimney Inspection & Sweep – O'Fallon, MO

"Joe and his team are the real deal. We had them out for a Level 1 chimney sweep before winter and were blown away by how thorough they were. They used a camera inside the flue and showed us exactly what was going on. No pressure, no upsell – just honest, expert service. I've already recommended them to four neighbors."

— Sarah M., O'Fallon, MO

⭐⭐⭐⭐⭐ Air Duct Cleaning – St. Charles, MO

"We just completed a home renovation and knew our ducts were filled with construction dust. The Mad Hatter team used their truck-mounted vacuum system and you could literally see the difference in air quality the same day. My wife's allergies have been so much better since. Professional, clean, and worth every penny."

— David R., St. Charles, MO

⭐⭐⭐⭐⭐ Dryer Vent Cleaning – Wentzville, MO

"I had no idea how clogged our dryer vent was until the technician showed me the lint blockage he removed. Our dryer had been taking two cycles to dry a load – now it dries perfectly in one. Should have called sooner! These guys were on time, professional, and got the job done right."

— Linda K., Wentzville, MO

⭐⭐⭐⭐⭐ Chimney Repair & Relining – Chesterfield, MO

"After a different company told us we needed a full chimney rebuild (for $8,000!), we called Mad Hatter for a second opinion. Jason did a forensic camera inspection and identified a cracked clay liner that could be resolved with a stainless steel relining system – saving us thousands. The work was done on time, correctly, and they cleaned up perfectly afterward. Integrity at its finest."

— Mike T., Chesterfield, MO

⭐⭐⭐⭐⭐ Real Estate Pre-Sale Inspection – Kirkwood, MO

"As a real estate agent, I've worked with dozens of home service companies. Mad Hatter is the only chimney and duct specialist I refer to my clients without hesitation. They are punctual, communicate clearly, and produce a thorough written report that holds up during closing negotiations. Joe and the team understand how important timing is in real estate – they've never let me or my clients down."

— Karen J., Real Estate Agent, Kirkwood, MO
