Chimney Doctors

What Chimney Doctors does

Chimney Doctors is a family-owned, full-service chimney and fireplace company headquartered in Burnsville, Minnesota, serving residential homeowners across the Twin Cities metropolitan area since 1997. The company provides a comprehensive service portfolio organized into three lines: core maintenance services (chimney sweeping, Level 1/2/3 inspections, creosote removal, gas fireplace tune-ups, chimney removals and replacements); repair services (stainless steel chimney relining with lifetime warranty, tuckpointing and repointing, partial-to-complete chimney rebuilding, crown repair, leak diagnosis and repair, professional vapor-permeable masonry waterproofing, and general masonry repair); and a product/installation line spanning gas, wood, and electric fireplaces, inserts, stoves, gas log sets, and proprietary ChimGuard chimney caps and accessories.

The company's underlying technology is predominantly skilled-trade rather than software-based. The core technical asset is human expertise: the owner, Steve Trumble, holds CSIA Master Chimney Sweep certification (#6835; 61st in the country) and is the only CSIA Master Certified chimney professional in Minnesota. The company employs the largest roster of CSIA-certified chimney technicians in the state, supplemented by NFI Woodburning and Gas Specialist certifications and a CDET-certified chimney diagnosis expert. A vertically integrated manufacturing capability exists through Sota Metal Fabrication LLC, a separate company founded by the owner that produces proprietary ChimGuard full-coverage chimney caps with heavy-duty stainless steel mesh, metal skirts, and standing seams, backed by a lifetime replacement warranty. All work is performed on-site at customer homes.

The business model is professional services plus hardware sales, with revenue generated from one-time transactional jobs (cleanings, inspections, repairs, installations) priced via free on-site quotes, plus product revenue from chimney caps, dampers, chase covers, and installed fireplace units sourced from 15 manufacturer partners (Majestic, Valor, Heatilator, Osburn, Kuma, Blaze King, Lopi, MF Fire, Modern Flames, SimpliFire, Dimplex, Marquis, RealFyre, HearthStone, Thelin). Distribution is direct-to-consumer via three local phone numbers, website booking, and contact forms, with no retail or e-commerce channel. Customer acquisition is driven by 1,100+ Google 5-star reviews, word-of-mouth referrals, local-SEO-optimized service-area pages covering 50+ cities, a multi-platform social presence, and a content-marketing blog. A 10% senior and military discount is offered on standard cleaning and inspection services.
