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 Allentown: What to Know First
We provide independent Copperfield chimney cleaning and sweep service in Allentown, with most jobs completed in a single visit and upfront pricing that matches the final invoice. A standard Copperfield sweep and Level 1 inspection runs $149-$219, while a Level 2 camera inspection for suspected liner or crown issues runs $289-$389. We’re not here to sell you parts your chimney doesn’t need.
This page is for homeowners in Allentown who’ve got a Copperfield liner, cap, or damper installed and want it serviced by technicians who know the product line without charging dealership prices. We’ve worked on Copperfield systems across the Lehigh Valley, from the older brick colonials near West Park to the split-levels out by Trexler Park. If you’re unsure what model you’ve got, we’ll identify it on arrival. Call (610) 632-1394 and a live person will pick up, any hour of any day.
How Copperfield Products Fail - and How We Fix Them
- Copperfield ProFlex liner panels separate at the seam joints after 12-18 years of Allentown freeze-thaw cycles. The Lehigh Valley’s temperature swings stress the 316Ti stainless steel at the crimped seams, especially in south-facing chimneys that heat and cool daily. We camera-inspect the full liner run, mark the separation points, and either re-crimp with a proper expansion joint or section-replace using compatible ProFlex segments. We’ve seen this exact pattern on three homes near 17th and Chew streets in the past two years.
- Copperfield Gelco chimney caps clog with creosote at the mesh screening, restricting draft and backing smoke into the house. The 3/4-inch mesh that keeps animals out also traps glazed creosote in Allentown’s humid shoulder seasons. We remove the cap, ultrasonic-clean the mesh in our truck, and check the underlying crown for spalling. If the cap frame is warped from past chimney fires, we source a direct-fit Gelco replacement or fabricate a custom cap with 5/8-inch mesh that drafts better in this climate.
- Copperfield Lyemance and Lock-Top top-sealing dampers corrode at the stainless steel cable guide. The cable housing sits in the flue gas stream, and Allentown’s sulfur-heavy coal-era masonry accelerates pitting. The damper won’t open fully or seal tight. We extract the old cable, chase the housing with a borescope, and install a replacement cable assembly from Copperfield’s service parts line. If the cast-aluminum frame is cracked, we quote a new damper body rather than patching something that’ll fail again next season.
- Copperfield DuraFlex relining sleeves sag in tall, uninsulated flues common in pre-1940 Allentown homes. The West Park neighborhood has dozens of these: 30-foot straight runs in unlined brick where the sleeve pulls away from the top plate. We find the sag point with a laser level during camera inspection, then install a DuraFlex support plate with a tensioning band or recommend a full reline if the sleeve has abraded at the thimble. The chimney doesn’t care what it looks like from the street. We check what’s inside.
- Copperfield chimney crowns poured with their proprietary blend develop hairline cracks that wick water into the flue. The blend sets hard but doesn’t flex with the brick below, especially on Allentown homes with soft Reading Formation brick from the 1920s. We map the crack pattern, grind to sound concrete, and apply HeatShield CrownCoat or pour a new Gelco-reinforced crown depending on depth. Either way, you get photos before and after, and a plain-English verdict on whether the repair buys you five years or twenty.
Our Copperfield Chimney Cleaning & Sweep Process
- 1
Call and schedule. A live person answers, confirms your Allentown address, and books a window. We ask if you know your Copperfield model or when it was installed.
- 2
Arrival and protection. Our technician lays floor and furniture protection, then runs a Level 1 or Level 2 inspection based on what you’ve reported. Copperfield components are identified by part number where accessible.
- 3
Camera diagnosis and documentation. For Level 2, we send the camera up the flue and capture video of every seam, joint, and transition. You see the footage on our tablet. We explain what’s normal wear and what needs attention.
- 4
Parts decision and upfront quote. If we need Copperfield OEM parts, we check availability and lead time. If a quality aftermarket equivalent from DuraFlex, HeatShield, or Gelco fits and saves money without voiding your remaining warranty, we present both options. The price we quote is the price on the invoice.
- 5
Cleaning, repair, and testing. We sweep to NFPA 211 standards, complete the agreed repair, and run a draft test with a digital manometer. Smoke draws properly, damper seals, cap vents. No surprises.
- 6
Written report and guarantee. You get photos, the video file, our findings in plain English, and the 90-Day Done Right Promise in writing. If something’s not right, we come back. No paperwork to dig up, no arguing.

FAQs
No. As an independent Copperfield service provider, we perform warranty-safe work using correct parts and procedures. We document everything with photos and part numbers so any future warranty claim with Copperfield has proper records. If your system is still under Copperfield’s original warranty, we note that in our report and flag any issues that should go through their channel first. Call (610) 632-1394 and we’ll check your install date.
A standard Level 1 sweep and inspection takes 45 minutes to 90 minutes for most Allentown homes. A Level 2 camera inspection adds 30 to 60 minutes depending on flue height and what we find. We complete most jobs in a single visit, and we’ll tell you before we start if your situation needs a return trip for parts. Book a morning slot if you want the full day available for any follow-up work.
Repair makes sense when the damage is localized, the liner is under 15 years old, and the remaining sections show no thinning or seam stress. Replace when we find multiple failure points, the steel has thinned below 0.005 inch, or the original installation used an undersized diameter for your appliance. We show you the camera footage and give both options with honest timelines. No replacement is suggested without evidence you can see.
Most common service parts, cables, and caps ship within two business days. ProFlex liner sections and specialty dampers sometimes take four to five days. Because we also stock and work with DuraFlex, HeatShield, and Gelco, we can often cross-reference a compatible part for same-day completion if you’re facing a heating deadline. We’ll tell you the real lead time before you commit, not after.
The NFPA recommends annual inspection for all chimney systems, including Copperfield. Sweeping frequency depends on use: wood-burning fireplaces need sweeping when creosote reaches 1/8 inch thickness, typically every cord of wood burned. Gas systems with Copperfield liners need less frequent sweeping but still need annual inspection for condensation damage and debris blockage. Allentown’s wet shoulder seasons accelerate corrosion, so we advise not skipping years even with light use. Call (610) 632-1394 to schedule - estimates are free.
