The Team Behind the Trucks

Mike founded this company in 1998 with a ladder, a set of brushes, and a conviction that chimney customers deserved straight answers. Twenty-five-plus years later, we're still family-owned, still showing homeowners photos before prices, and still answering the phone at 2am — because that's when chimneys pick their moments.

Every technician is trained, insured, and background-checked. Every job ends with your home as clean as we found it. Read our story →

Common Questions

How often should a chimney be cleaned in Colorado?

The NFPA recommends annual inspection and cleaning as needed. Along the Front Range, where fireplaces work from October into April, annual service is the practical baseline — and heavy wood burners, especially in the mountain communities, often benefit from a mid-season check.

Are you really open 24/7?

Yes — the phone at 720-310-3798 answers around the clock, every day. Routine work gets scheduled at your convenience; emergencies (chimney fires, storm damage, CO alarms, active leaks) dispatch immediately, day or night.

What areas do you cover?

Roughly 65 miles around each of our three bases — Denver, Fort Collins, and Colorado Springs — which covers the Front Range from the Wyoming line down past Pueblo, and from the eastern plains up into the mountain towns. Over 100 communities have dedicated pages on this site.

Do you give free estimates?

Always: free, written, and preceded by an honest look at the system. You'll see photos of anything we find before you see a price, and the price you approve is the price you pay.

Do you handle both wood and gas fireplaces?

Both, plus pellet and wood stoves, inserts, and factory-built systems — and the dryer vent while we're at it. Whatever vents through your roof, we service the complete system.
