Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Copperfield Chimney Cleaning & Sweep in Boulder: What to Know First
We provide independent Copperfield chimney cleaning and sweep services throughout Boulder, with most inspections booked within a week and a written price delivered before any work begins. A standard Copperfield Level 2 inspection with camera scan, sweep, and documented photo record runs $285-$395 for most Boulder homes. We’re not affiliated with or authorized by Copperfield - we’re an independent service provider who happens to work on a lot of their systems in this market.
This page is for Copperfield owners in neighborhoods like Mapleton Hill, Chautauqua, and the newer builds off Arapahoe who need annual maintenance, suspect a performance issue, or want a second opinion on a replacement quote. Corrine Halstead and our crew have inspected and cleaned Copperfield liners, caps, and chase covers across more than 38,000 chimney visits since 2009. Call (970) 598-0453 to book or request a free estimate.
How Copperfield Products Fail - and How We Fix Them
- Copperfield UltraPro stainless liners with premature weld-seam corrosion. We see this most in Boulder homes above 5,400 feet where thermal cycling is aggressive and winter humidity drops below 15 percent. The seam opens slowly, leaks condensation into the chase, and shows up as water staining on the ceiling near the fireplace. We camera-scan the full length, document the breach under Haven Standard Clause 4, and quote a replacement with an Olympia Chimney smooth-wall liner if the UltraPro is out of warranty.
- Copperfield WindBeater caps with bent or missing spark-arrestor mesh. Boulder’s wind corridor - especially west of Broadway and up toward the foothills - deforms the .023-inch mesh over two to three seasons. Once the mesh gaps, embers can exit and birds enter. We measure the flue exact and source a Gelco replacement cap through Haven’s buying network if the WindBeater frame is still square; if the frame is twisted, we quote a new cap assembly with written price before installation.
- Copperfield Pro-Form chase covers with corner-seam rust-through. The painted steel version, common on 2015-2019 Boulder builds, traps water at the cross-break corners where the factory caulk shrinks in dry winters. Rust stains on the chase siding are the tell. We remove the cover, photo the deck condition, and fabricate a replacement from heavier-gauge steel or copper through our Famco supplier - never re-caulking a rotted cover and calling it done.
- Copperfield RoundFlex liners with ovalization in offset flues. The multi-ply construction can deform where an old Boulder chimney has a sharp offset between floors, typically in pre-1950 Mapleton Hill homes. Ovalization reduces draft and accelerates creosote buildup at the pinch point. We camera-locate the deformation, measure the remaining round diameter, and recommend either a custom ovalization repair with HeatShield refractory or a full liner replacement if the structural integrity is compromised.
- Copperfield Class A chimney systems with joint-separation in earthquake-prone installs. Boulder County’s seismic zone means the twist-lock joints on exterior Class A stacks can work loose over five to seven years, especially where snow load adds stress. We inspect each joint with a borescope from the top down, reseat and lock the affected sections, and pressure-test the assembly before signing off.
Our Copperfield Chimney Cleaning & Sweep Process

- 1
Booking and confirmation. You call (970) 598-0453 or request online. We assign a named, background-checked technician and text you when they’re en route - Haven Standard Clause 2, “Arrive on schedule.”
- 2
Level 2 camera inspection. We run a high-resolution camera the full flue length before touching anything. For Copperfield systems, we’re documenting liner seam condition, cap mesh integrity, and any chase-cover rust pattern specific to that product line. The camera doesn’t guess. Neither do I.
- 3
Written price and scope. Corrine or your assigned tech shows you the footage, names the finding, and delivers a written price with scope and warranty before any work starts - Haven Standard Clause 1, “Have it in writing.” No exceptions.
- 4
Sweep and service with correct parts. We use rods and brushes sized to your Copperfield flue diameter, not generic hardware-store kits. If parts are needed, we source OEM Copperfield when warranty requires it, or quality aftermarket from DuraFlex, HeatShield, or Gelco through Haven’s buying network when it doesn’t - and we tell you which and why.
- 5
Testing and documentation. We run a final camera pass, perform a draft test where applicable, and deliver your documented photo record on the spot - Haven Standard Clause 4, the practice we’ve held since 2009. Your warranty and scope are in writing before we leave.
- 6
365-Day Done Right Promise. If anything in our scope fails due to our work or materials, we make it right. The promise is stamped on every job.

Why Boulder Homeowners Call Emberly Chimney Cleaners Boulder for Copperfield Work

We’ve cleaned and inspected Copperfield systems in Boulder since 2009 - through the dry winters that shrink caulk, the wind events that warp caps, and the altitude that stresses weld seams differently than sea-level installs. Our technicians are uniformed, background-checked, and named on your appointment; you’ll know who’s coming and when.
The Haven Standard means you get a written price before work starts, a documented photo record when it’s done, and a 365-Day Done Right Promise on every job. We source materials through our buying network - DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - to keep pricing honest without marking up retail parts. And when you call (970) 598-0453, a live person answers, 24 hours a day.
FAQs
No - annual professional sweep and inspection is required to maintain most Copperfield liner and component warranties, provided the work is documented. We deliver that documentation as standard under Haven Standard Clause 4, with dated photos and a written scope. Call (970) 598-0453 to schedule - estimates are free.
We source both. If your Copperfield liner or cap is under warranty and OEM is required to preserve coverage, we procure through our supplier network. If warranty has expired or the component is discontinued, we quote quality aftermarket from DuraFlex, HeatShield, or Gelco - usually at lower cost with equivalent or better specifications - and we tell you which we’re using and why before ordering.
The camera shows it. We run a full Level 2 inspection and show you the footage: seam separation, ovalization, or corrosion pitting gets measured and documented. If the defect is localized and the liner structure is sound, we may recommend a HeatShield refractory repair. If the damage is extensive or the liner has exceeded its service life, we quote replacement with written price and scope before any work. You’ll see what we see and decide.
NFPA 211 recommends annual inspection; sweep frequency depends on use and fuel. In Boulder’s dry climate, wood-burning systems often build Class II creosote faster than back east due to rapid draft draw at altitude. Gas systems need less frequent sweep but still require annual inspection for condensate damage and cap integrity. We inspect first, then tell you if sweep is needed this year - no automatic upsell.
Class III creosote can ignite at 451°F and reach 2,000°F in a chimney fire, cracking liners and exposing framing. A failed liner or cap can also vent carbon monoxide into living space. These are real risks, not scare tactics - and they’re preventable with annual inspection. If your system is overdue, call (970) 598-0453 for a camera scan and honest assessment of condition. Estimates are free, and we’ll tell you plainly if work can safely wait.
