Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Trusted Chimney Sweep for Westminster Homeowners
A wood fire that smokes into the room instead of going up the flue usually means creosote has built up enough to narrow the chimney, and that is exactly the kind of thing a proper sweep catches before it becomes a safety problem. Westminster sits high on the Front Range, where cold nights arrive early and fireplaces see heavy use from October on, so chimneys here work hard. Our technicians have up to 9 years of experience, and we do the whole job under one roof: we inspect it, we sweep it, and if something needs repairing, we handle that too. We’re licensed and insured, and we don’t recommend work you can’t see the reason for. We answer 24/7, so call (844) 785-0715 to book a sweep, and we’ll get you on the schedule quickly for same-day service when the calendar allows.
Chimney Sweep Services
Chimney Sweep Services cover the whole job of clearing the flue, checking the firebox and smoke chamber, and confirming the cap and screen are doing their work. You need this once a year with regular fires, or after a season of burning dirty wood that leaves glaze on the liner. At Hillcrest Chimney Sweep we inspect, sweep and repair, so nothing gets handed off to someone else mid-job. A standard sweep in Westminster typically runs $180 to $340 depending on how much creosote has accumulated and how accessible the flue is. We use professional-grade tools and rods, and we work carefully around your firebox so the masonry stays intact.
Routine Annual Sweeps
An annual sweep clears soot and creosote before it hardens into a stubborn glaze that’s harder to remove. We run a camera check and give you a written report on what we find, so you know the condition of your chimney rather than guessing. If the flue is clean and clear, we tell you that and nothing more.

Heavy Creosote Removal
Wet wood and starved air flow produce glaze that clings to the liner and resists ordinary brushing. We use the right rods and brushes for the flue material, and we don’t force anything that risks cracking a clay tile. When the deposit is too thick for a straight sweep, our repair side handles it with resurfacing or liner work, and we explain the options before booking anything.

Chimney Cleaning
Chimney Cleaning is the detailed side of a sweep: working soot and ash out of the smoke chamber, the shelf at the damper, and the firebox itself, not just running a brush down the flue. If you’ve burned for a full season, if you can smell smoke when the fire is out, or if you’ve just bought a Westminster home and don’t know when the last cleaning happened, this is the appointment to book. We do the work with drop cloths and a shop vac sealed against the opening, so the room stays as it was. Cleaning typically runs $180 to $340. If we find a problem that needs more, we show you the camera footage before anyone suggests a repair.
Smoke Chamber and Damper Care
The smoke chamber is the sloped area above the damper, and it’s where hard-to-reach soot likes to collect. We reach it with flexible tools and check the damper seals while we’re there. A damper that doesn’t close right costs you heat and lets cold air down the flue when the fireplace is idle.
Keeping the House Clean
Dust is the thing homeowners dread about a sweep, and there’s no reason it should happen. We lay protective covers, keep the vacuum sealed to the firebox, and clean up as we go. When we leave, the room looks the way it did when we arrived.
Fireplace Cleaning
Fireplace Cleaning handles the parts you actually see and touch: firebox walls, grate, andirons, the hearth, and the glass on an insert, so the whole fireplace is ready to use again. It’s the right service when the firebox is stained with soot, when ash has built up past the grate, or when you’re getting a home ready for the first cold snap. We treat it as its own job, separate from sweeping the flue, and do it without letting ash get into the room. Fireplace cleaning in the Westminster area generally starts around $120 to $200 as part of a sweep or as a stand-alone visit. We’ll tell you honestly whether it needs doing at all.
Firebox and Hearth Cleaning
Soot on the firebox walls isn’t just cosmetic; heavy buildup can mask cracks that let heat into the masonry. We clean the walls and hearth and check for cracks while the surface is clear. Any damage we find gets photographed and shown to you.
Insert Glass and Gaskets
Smudged glass on a wood or gas insert is a sign the air wash is working overtime or the gasket isn’t sealing. We clean the glass and check the door gasket while we have access. A worn gasket is a small repair that keeps the insert burning efficiently and predictably.
Chimney Services
Chimney Services means the full life cycle of your chimney handled by people who do nothing else: inspection, sweep, and repair, in that order, with one point of contact throughout. You need it whenever the chimney has gone more than a year without a look, or when something has changed, like a draft problem, a new appliance, or a storm that dropped limbs on the roof. We don’t do gutters or vents or anything else, which keeps our focus tight. Pricing depends on what the chimney actually needs, and the written estimate sets the final figure before any work begins. With Hillcrest Chimney Sweep you get one company, one report, and one clear recommendation.
One Company, No Handoffs
We inspect it, sweep it, and fix it, all under one roof, so you aren’t coordinating a sweep company and a repair contractor who blame each other. The person who finds a problem is the person who fixes it. That means fewer surprises and a straighter answer.

Focused on Chimneys Only
Every job we take on is chimney work, so the expertise doesn’t get divided across unrelated trades. When we recommend DuraFlex liner work or HeatShield resurfacing, it’s because we do that work regularly, not because it’s a sideline. Trade-specific focus shows in the details.
Chimney Sweep Certified
Chimney Sweep Certified means the technician who sweeps your chimney is trained and credentialed for the specific work, not a general handyman with a brush. That matters most when the sweep turns up a defect, because reading a flue correctly takes training and a trained eye for what the camera is showing. We inspect, sweep and repair under one roof, and our technicians have up to 9 years of experience in that order of work. We’re licensed and insured. Certifications are the baseline, not a sales pitch. Every sweep comes with a camera inspection and a photo report you keep, typically $180 to $340 for the visit. You’ll know what was found and why it matters.
Camera Inspection Included
We run a camera down the flue during every sweep, so the review is based on footage rather than a guess. If we find a crack or a gap in the liner, you see it on screen before we discuss options. Nothing is recommended without camera evidence you can look at yourself.
Reports You Can Keep
You get a written report and photos from the visit, which is handy for insurance, for a home sale, or for remembering what your chimney looked like last year. When you call us the next time, we have a baseline to compare against. Records turn a vague worry into a clear answer.
Gas Fireplace Cleaning
Gas Fireplace Cleaning focuses on what a gas fire leaves behind: dust, cobwebs, and a faint film on the logs and glass, plus the venting path that carries exhaust out of the house. It’s worth doing annually, particularly before the heating season starts, because a clean burner and clear vent line are part of how the fireplace stays safe to run. We sweep and clean gas units as part of our chimney work, and we inspect the venting for blockages, bird nests, or a disconnected section that a camera can spot. Gas fireplace cleaning in Westminster usually runs $120 to $220 depending on the unit. We don’t take shortcuts on gas; if something is off, we tell you plainly and recommend a professional repair rather than a workaround.
Burner and Log Detail
Dust on the burner ports and logs can change how the flame burns and leave soot marks above the opening. We clean those surfaces carefully and check the flame pattern while it runs. If the flame looks wrong, that’s a sign to have the unit serviced, not a sign to keep using it.
Venting and Carbon Monoxide Check
A gas fireplace sends exhaust up the flue, and a blocked or disconnected vent can let carbon monoxide into the living space. We check the vent path with a camera and confirm it’s clear. This is not a place for a wait-and-see attitude, and it’s cheap insurance against a silent problem.
Chimney Maintenance
Chimney Maintenance is the ongoing rhythm of keeping a chimney sound: a sweep and inspection each year, a check on the cap and crown before winter, and small repairs handled before they become big ones. You need it because Westminster’s freeze-thaw cycles work on masonry all winter, opening hairline cracks in the crown and letting water in where it shouldn’t be. Water is the slowest and most expensive chimney problem there is, and a cap that fits properly is the cheapest defense. We use Gelco and Famco caps and covers for that reason, and we’ll say plainly when a repair can safely wait until spring. Routine maintenance visits in Westminster typically run $180 to $340. Keeping ahead of these details protects both the chimney and the house.
Caps, Crowns and Water Intrusion
A missing or damaged cap lets rain, snow, and animals straight into the flue, and a cracked crown gives water a path into the masonry. We check both during every maintenance visit and fit a proper cap when one is needed. Preventing intrusion costs far less than repairing what water does over a few winters.
Seasonal Timing
The ideal time to book maintenance is before the first burn, in late summer or early fall, so you’re not starting the season with a dirty flue. If you’re already into winter, a sweep still helps, and we can plan the repairs for when the weather allows. There’s no bad month to get the chimney looked at.
Brands We Service
We work with professional-grade materials from brands chimney specialists rely on. DuraFlex flexible liner systems are what we turn to for deteriorated or improperly sized flues, and we know where those liners wear, kink, and lose their insulation value. HeatShield ceramic resurfacing is our choice for repairing a liner that’s still structurally sound but pitted or cracked, and we understand how the compound cures and how it holds up over years of heating cycles. When we recommend either, it’s because we install them regularly and know how they behave.
Caps and covers come from Gelco and Famco, and working with those product lines means we can match the right cap to the flue size and the local weather without improvising. Olympia Chimney and Copperfield round out the material knowledge we bring to liner and venting work. Whether you have a DuraFlex liner, an Olympia Chimney cap, or any other make, we can help. We don’t claim to be a dealer or to stock parts; we bring trade-level product knowledge to the repair. That’s the difference between a company that knows these brands and one that glances at a catalog the morning of the job.

AfterSigns You Need a Pro Right Now
- Smoke rolling into the room. A fireplace that used to draft fine but now spills smoke usually has a partial blockage or a restricted flue. Don’t keep burning and hope it settles; a camera inspection finds the cause in minutes.
- A strong creosote smell in warm weather. That acrid odor on a hot day means creosote is present and off-gassing. It’s a reminder to book a sweep before the next season starts.
- Visible soot or black staining above the firebox. Soot on the wall or mantel is a sign the draft is struggling or the firebox is leaking. It can indicate a crack that needs a professional repair, not a paint touch-up.
- Cracks in the firebox brickwork or mortar joints. Small cracks in the firebox can let heat reach the masonry and the framing behind it. Have it checked; this is one area where a small problem is worth taking seriously early.
- Water, rust, or animal debris in the flue. A cap that’s failed shows up as dripping water, rusted metal, or nesting material when the damper opens. Get the cap and crown checked before the damage spreads into the masonry.
Our Process, Step by Step
- 1
Book the visit and agree the scope. We talk through what you’ve noticed, schedule the sweep, and confirm what the appointment includes and what it costs before we arrive. The price is set per job, and the estimate is free.
- 2
Inspect before we sweep. We run a camera down the flue and look over the firebox, damper, smoke chamber, cap and crown, documenting what we see. This is what tells us what kind of sweep the chimney actually needs.
- 3
Sweep with the right tools. Brushes and rods are chosen for the flue material, and we seal the vacuum and lay protective covers so soot stays contained. We work down from the top and finish at the firebox.
- 4
Report what we found. You get the photos and a plain explanation of the chimney’s condition, including anything that needs attention and how soon. Nothing is recommended without camera evidence you can review.
- 5
Repair only if it’s needed. If something needs repair, we quote it in writing and explain what can safely wait until spring. You see the written estimate set the final price before any work begins.
How Much Does Chimney Sweep Cost in Westminster?
Chimney sweep prices in Westminster run mostly on the same ranges. A standard sweep for a wood-burning fireplace typically runs $180 to $340, and that depends on the level of creosote, the length and pitch of the flue, and whether the roof access is straightforward. A gas fireplace cleaning is on the lower end, usually $120 to $220, because there’s no creosote to remove. Fireplace cleaning as part of the visit generally starts around $120 to $200. If the inspection turns up a liner problem, HeatShield resurfacing or a DuraFlex liner replacement is a separate repair, and that’s where the estimate gets tailored to your chimney.
What moves the price: heavy glaze creosote takes more time and specialized tools, a steep or complex roofline adds difficulty, and a chimney with multiple flues has more to sweep. What shouldn’t move it: whether you call for an estimate, which is free. To avoid overpaying, ask for the scope in writing, make sure the price includes the inspection and the report, and be wary of anyone who recommends liner work before you’ve seen camera footage. Every estimate we give spells out what’s included and what the final price is; there’s no service-call fee or surprise charge on the day. When we tell you the chimney is clean and doesn’t need anything, that’s a complete answer, not an upsell. Call (844) 785-0715 for a free estimate.
