Why Simmons Brothers Chimney Sweeps
- Hearth Safety Is All We Do — We aren't a general contractor who sweeps chimneys on the side. Fireplace service and chimney cleaning is our entire focus — which means our diagnosis is sharper, our safe-first recommendations are more reliable, and your flue health never gets treated as an afterthought.
- Written Scope Before We Touch Anything — Before any creosote removal, masonry repair, or damper service begins, we hand you a clear written scope of what we found and what we recommend. No verbal estimates that change at invoice time — just honest, transparent work with a quality check at every stage.
- Full-Season Support, Not Just a Sweep — From season opening through off-season protection, we provide wood-burning guidance, burn quality coaching, CO safety checks, and cap replacement so your fireplace performs beautifully all winter and stays protected when the season ends. We're your annual service partner, not a one-time visit.
- Licensed, Insured, and Respectful of Your Home — We are fully licensed, insured, and bonded — and we treat your living-room centerpiece with the same respect we'd give our own. Protective covers go down, the work area stays clean, and we follow up after every job to make sure you're satisfied with the care your chimney received.
What Our Customers Say
Trusted by homeowners across Westminster, CO
"I've had my chimney serviced by three different companies over the years and Simmons Brothers is the only crew that actually showed me the camera flue scan and explained the liner condition before they started. I felt informed, not sold to. Our fireplace has never burned cleaner."
— Carol M., Westminster, CO
"They arrived on time, put down protective covers, and handed me a written scope of everything they planned to do. The creosote removal was thorough and they found a cracked damper I didn't know about. Honest work from a crew that clearly takes hearth safety seriously."
— Dave R., Broomfield, CO
"What I appreciated most was the follow-up call after the job. They asked if we had any questions about the wood-burning guidance they left behind. That kind of comfort and care is rare. We've already scheduled our annual service for next fall."
— Susan T., Arvada, CO
"We have an older heritage hearth that most sweeps won't touch because of the masonry tuckpointing it needs. Simmons Brothers not only handled it, they gave us a timeline, kept us updated, and did a quality check before they packed up. The fireplace looks and drafts better than it has in years."
— Mark L., Westminster, CO
Frequently Asked Questions
How often should I schedule a chimney inspection and cleaning?
The National Fire Protection Association recommends an annual chimney inspection for any fireplace that sees regular use — and a full chimney cleaning whenever significant creosote buildup is found. For most Westminster homeowners, a season prep visit in early fall is the right rhythm. It covers your camera flue scan, smoke shelf cleaning, draft testing, and a liner condition report before the first fire of the year.
What is creosote and why does it matter?
Creosote is a byproduct of incomplete combustion that accumulates on the interior walls of your flue during wood-burning. In its early stages it's flaky and brushable. In later stages it becomes a dense, tar-like substance that dramatically increases fire risk. Creosote removal is one of the most important steps in fire risk reduction, and our sweep will assess your buildup level and recommend the appropriate cleaning method during every inspection.
Do you offer masonry repair and crown sealing, or just cleaning?
We provide comprehensive chimney care that goes well beyond basic sweeping. Our services include masonry tuckpointing, crown sealing, chimney flashing service, cap replacement, spark arrestor installation, damper service, and water entry prevention. If your chimney has a structural or weatherproofing need, we'll identify it during your inspection and provide a written scope for the repair.
Can you service gas fireplaces and inserts, not just wood-burning?
Yes. We offer gas insert support including pilot checks and CO safety checks for homeowners with gas appliances. While a gas fireplace produces less creosote than a wood burner, the flue, venting components, and combustion safety still require regular attention. We'll evaluate your unit's code-compliant status and make safe-first recommendations based on what we find.
What should I expect on the day of my chimney service appointment?
Our clean crew will arrive within the scheduled window, introduce themselves, and lay down protective covers before any work begins. We'll walk through our season opening checklist, conduct a camera flue scan, and present you with a written scope of our findings. Work is performed with clear communication throughout, and we do a quality check before we leave. You'll also receive a liner condition report and any wood-burning guidance relevant to your setup.
How do I know if my chimney needs a repair versus a routine cleaning?
That's exactly what our chimney inspection is designed to determine. Signs that something beyond a standard sweep may be needed include visible cracks in the firebox or crown, draft issues or smoke backing into the room, water stains on the ceiling or firebox, and visible gaps in your chimney flashing. Many of these issues are invisible from the outside, which is why a camera flue scan and firebox integrity check are included in every service visit — so you get a complete picture, not just a surface-level assessment.
