Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Westminster Homeowners Call Grafton Chimney Sweep for Chimney Sweep
Most Westminster homes we open up have a story in the flue. A 1950s ranch off 80th and Federal tends to have a clay-tile liner that’s been quietly cracking for years. A newer build on the northwest side usually has a factory-built metal chimney with its own set of failure points. You need a sweep who reads the house before touching the brush, and that’s the part we take seriously.
Westminster homeowners call us because we repair what we find. If a sweep turns up a spalling crown or a liner that’s never been right for the appliance vented into it, we can scope that repair and often do it the same visit instead of referring you out. We carry professional-grade materials from HeatShield, DuraFlex, Gelco, and Copperfield, and our technicians install them directly.
We serve homeowners across Westminster and the surrounding metro, including Arvada, Commerce City, Northglenn, and Denver. When you call, we’ll give you a straight answer on scheduling and a flat price agreed before we book anything.

Chimney Sweep Certified in Westminster
A Chimney Sweep Certified job in Westminster means more than running a brush up the flue. It’s a proper clean, a check on what the flue is made of, and a camera look at the parts a brush can’t reach. In Westminster’s older housing stock, that extra step is what tells us whether you’re looking at routine soot or a liner that needs real repair. A standard sweep in Westminster typically runs $185 – $290; adding a Level 2 camera inspection usually lands in the $250 – $400 range, depending on flue configuration.
What a Standard Sweep Covers
We brush the flue, clean the firebox and smoke chamber, check the damper, and clear out the firebox floor. You get a report of what we found, with photos where they help.
When a Camera Inspection Is Needed
Any unlined stack, any flue with visible tile cracks, and any appliance vented into a chimney that wasn’t built for it gets a camera. We show you the footage before we recommend anything.
Gas Fireplace Cleaning in Westminster
Gas Fireplace Cleaning in Westminster is often skipped because there’s no visible soot to worry about. That’s a mistake. Gas units still build up dust, debris, and oxidation on the burner and logs, and a dirty burner can produce incomplete combustion. A gas fireplace service in Westminster typically runs $150 – $250 depending on the unit and what needs to come apart. We clean the burner assembly, check the venting, verify the flue is clear, and inspect the fuel lines and surrounding masonry.
What Gets Checked on a Gas Unit
We pull the logs and clean the burner ports, inspect the vent termination, and check for signs of spillage or blockage. If something’s off with the venting, we flag it before you use the fireplace again.
When to Book the First Service
Most manufacturers recommend an annual service, and we agree with that schedule. If you’ve never had the unit opened up since moving in, that’s your sign.
Trusted Brands We Service in Westminster
We work with DuraFlex, HeatShield, Gelco, and Copperfield on Westminster chimney work. HeatShield is our go-to for liner resurfacing when the flue is compromised but still serviceable – it restores the liner without pulling the whole thing out. When resurfacing won’t hold, DuraFlex flexible liner systems let us do a complete reline in the same job. We keep turnaround fast because the materials are already specified and the repair is scoped before we leave the driveway. No “we’ll order it and come back in three weeks.” No handing you off to another company for the liner work either. We stock nothing; we source what the job needs and install it ourselves.
Common Chimney Sweep Problems We See in Westminster Homes
- Cracked clay tile in mid-century flues. Westminster’s expansive clay soil and the 2013 Front Range floods left many 1950s and 1960s flues with hairline tile cracks or debris-packed stacks. A brush can’t fix that – only a camera reveals it.
- Third-degree creosote mistaken for ordinary soot. Glazed, tar-like creosote doesn’t brush out. When it’s treated as a routine sweep, the real scope gets missed and the problem gets re-sold later.
- Appliances vented into chimneys never designed for them. A furnace or water heater tied into an old masonry stack changes what the flue needs to do. Without an inspection, the smoke chamber, damper, and crown never enter the conversation.
- Exterior chimney freeze-thaw damage. Westminster’s swings above and below freezing accelerate masonry spalling, and exterior chimneys take the brunt of it. Catching it at the crown stage prevents a rebuild.

FAQs About Chimney Sweep in Westminster
Because 1950s Westminster flues are the most likely in the city to have hairline tile cracks you can’t see from the firebox. Decades of expansive clay soil movement and the 2013 Front Range floods did damage that a brush won’t reveal. A camera run costs less than a liner you didn’t need. Call (833) 749-6226 for an exact quote – estimates are free.
A Level 1 is the annual visual check and it’s right when nothing has changed. A Level 2 adds a camera and is what you want for any new home purchase, any appliance change, or any suspected flue problem. Level 3 – opening the wall – only when the camera shows a defect that requires it. Call (833) 749-6226 and we’ll tell you honestly which one you need.
Probably not, and that’s the honest answer. Glazed, third-degree creosote is hard and tar-like and doesn’t respond to a standard brush. It needs either chemical treatment or, in advanced cases, rotary cleaning before we can even assess the liner. Burning hot fires and using dry wood slows creosote buildup, but once it’s glazed it’s a professional job. Call (833) 749-6226 for a quote.
Yes – factory-built metal chimneys require the manufacturer’s specified brush and technique, and the inspection checklist is different from masonry stacks. These units are common in the newer northwest Westminster construction, and they tend to fail on joints and vent terminations rather than on the flue interior. Call (833) 749-6226 and we’ll scope the job correctly.
Water stains on the ceiling near the chimney, rust streaks on the firebox, loose mortar at the top of the stack, or a damper that sticks when it’s wet are the classic signs. Those point to the crown or flashing, not the flue liner, and diagnosing correctly saves you from a liner you don’t need. Call (833) 749-6226 – estimates are free.
