Keeping Your Home Safe, Clean, and Efficient
At The Mad Hatter Service Company, we’ve built our reputation on keeping St. Louis homes running safely. Your chimney and venting systems require regular maintenance to prevent hazards and operate efficiently. Our experienced team delivers thorough, reliable maintenance and preventative care.
Our Chimney Services
1. Professional Chimney Sweeping
Creosote buildup is the leading cause of chimney fires. Our comprehensive sweeping service removes dangerous soot and creosote from your flue, ensuring a clear path for smoke and combustion gases to exit your home safely.
-
Best for: Active wood-burning fireplaces and stoves used seasonally or regularly.
2. Gas Appliance Clean & Checks
Gas fireplaces and appliances are low-maintenance, but they are not no-maintenance. We inspect and clean gas logs, burners, and venting systems to ensure proper ignition, prevent carbon monoxide hazards, and keep your system burning beautifully.
-
Best for: Annual pre-winter maintenance for gas fireplaces and inserts.
3. Level 1 Visual Inspections
Included with our sweeping services, a Level 1 inspection is our standard baseline check. If your chimney usage hasn't changed and you aren't experiencing any performance issues, we examine the readily accessible portions of your chimney’s interior and exterior to ensure everything is in sound working order.
4. Level 2 Chimney Inspections
Specialized Inspections & Diagnostic Audits
🛑 Buying a home, filing an insurance claim, or experiencing a complex chimney draft issue?
NFPA 211 standards require a deeper look. To provide our customers with the absolute highest level of consumer protection and unbiased reporting, The Mad Hatter has partnered with The Chimney Safety Firm real estate, insurance, or legal inspections. Instead, we partner with The Chimney Safety Firm—a strictly non-bias, forensic diagnostic agency that does not perform sweeps or repairs. They offer one exclusive service: The Forensic Diagnostic Chimney Audit.
We seamlessly refer all of the following to their specialized team:
-
Real Estate Transactions: Level 2 inspections required for home sales and transfers.
-
Insurance & Legal Claims: Official forensic documentation following a chimney fire, lightning strike, or structural shifting.
-
Complex Problem Solving: Advanced diagnostics for recurring draft issues, mysterious leaks, or structural red flags.
By separating maintenance (The Mad Hatter) from un-biased forensic auditing (The Chimney Safety Firm), you can rest assured there is never a conflict of interest—just pure, accurate data regarding the safety of your home.
