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 Liner & Rebuild in Yonkers: What to Know First
Copperfield chimney liner and rebuild work in Yonkers typically runs $1,800 to $6,400 depending on whether we’re replacing a liner, rebuilding the flue, or taking the stack down to the roofline and starting over. As an independent Copperfield service provider, we’re not a factory warranty shop, but we know these liners cold, and most jobs are completed in one to three days once parts land. If you own a Copperfield liner or a home with one installed, this page covers what actually goes wrong, what it costs to fix in Yonkers, and what you should ask before anyone touches the stack. Call (551) 212-3526 and we’ll put a written price in front of you before any work starts.
How Copperfield Products Fail - and How We Fix Them
Copperfield makes a solid liner, but every product line has its weak points. Here’s what we see in Yonkers homes, year after year:
- Copperfield 316L flexible liners develop pinholes at the corrugation valleys, not the peaks. This is specific to how the alloy flexes during install. Condensation pools in the valleys, the acids in flue gas sit there, and microscopic perforations start. We find these with the camera, not by guesswork. Fix: full liner replacement when pinholes cluster, or a HeatShield resurfacing if the host pipe is structurally sound.
- The Copperfield rigid stainless flue sections show seam separation at the twist-lock joints. We mostly see this on their older oval rigid line in Yonkers colonials built before 2005. Thermal cycling works the joints loose over 15-20 winters. The fix isn’t always a full liner; sometimes re-seating and banding the joints is enough, if the metal gauge still reads healthy.
- Copperfield terra cotta flue liners spall when a Yonkers chimney gets hit with freeze-thaw cycles. Spalling means the inner face of the clay tile flakes off in chunks. The tiles are fine in mild climates, but Yonkers swings from 20-degree nights to 50-degree days mid-winter, and moisture in the masonry expands and contracts. The result is broken flue sections, which is a rebuild job, not a liner job.
- Copperfield caps and crowns crack at the crown-to-flue transition. This isn’t a Copperfield defect so much as a Yonkers weather reality. Water gets in, freezes, and the crown splits. We see it on the Copperfield multi-flue caps over two-story homes near the Hudson. The fix is a proper crown rebuild with an expansion joint, then a new cap.
- Improper liner sizing. This is the biggest one. A Copperfield liner that’s undersized for the appliance creates draft problems and excessive creosote. We regularly pull liners in Yonkers homes that were sized for a different stove or furnace, not the one actually connected. That’s an install error, not a manufacturing issue, but it means the liner has to come out and be resized.
Our Copperfield Chimney Liner & Rebuild Process

- 1
Call and book the camera inspection. We answer live, 24/7. You call (551) 212-3526, we schedule a time, and a named tech shows up in uniform with the camera rig.
- 2
Level 2 camera scan, every time. We run the camera down the full flue before touching anything. You see the footage on screen as we go, and we record it. Clause 4 of the Haven Standard: documented photo record on every job.
- 3
We show you what we found, in plain terms. Pinholes, spalling, seam separation, a cracked crown. You’re not taking our word for it, you’re looking at the camera feed.
- 4
Parts decision: OEM vs. quality aftermarket. We source Copperfield OEM when it’s available and the warranty makes sense. If a Copperfield part is backordered or overpriced, we’ll quote a DuraFlex or HeatShield alternative and tell you exactly what changes. You get the written price and written scope before anyone starts, and you decide.
- 5
The rebuild or liner replacement. We do the work, run a second camera pass to document what’s in place, and hand you the photo record plus the written warranty.
- 6
365-Day Done Right Promise. If something isn’t right, we come back and make it right. That’s stamped on every job.

AfterWhat Copperfield Chimney Liner & Rebuild Costs in Yonkers
Here are the numbers we quote most often for Copperfield work in Yonkers:
- Stainless steel liner replacement (single flue, one story): $1,800 to $2,900
- Flexible liner install for a wood stove or furnace, Copperfield-compatible: $1,400 to $2,600
- Partial chimney rebuild (above the roofline, crown and top courses): $2,200 to $4,300

- Crown rebuild and cap replacement: $800 to $1,700
Price moves with access, roof pitch, and what the camera finds. A two-story Yonkers colonial with a steep roof costs more to rig than a single-story ranch off Central Avenue. We never give a price without the camera scan first. Call (551) 212-3526 and we’ll give you a written number, not a verbal ballpark.
Why Yonkers Homeowners Call Level Two Chimney Yonkers for Copperfield Work

Most companies in Westchester charge for a flashlight look and call it an inspection. We’ve been running camera-scan documentation as the default since 2009, and that practice became Clause 4 of the Haven Standard. When you hire us for Copperfield work, you get the footage, the written price, the written scope, and the written warranty before a single brick moves. Corrine Halstead built this company on the idea that the camera doesn’t lie, and neither does the quote. We also carry the multi-brand backup: if a Copperfield part won’t work for your setup, we’ll quote DuraFlex, HeatShield, or Gelco alternatives and show you the difference. Live phone, real people, no voicemail tree. That’s it.
FAQs
If we use Copperfield OEM parts, no. If we use a quality aftermarket alternative like DuraFlex or HeatShield, that’s a decision you make with the written quote in hand. We’ll tell you exactly what the warranty implications are before you sign anything. The camera doesn’t lie, and neither does the quote.
You don’t, until a camera goes down the flue. Pinholes and seam separation don’t announce themselves. Signs like a smoky fireplace, a new draft smell, or visible flue tile chunks in the firebox are clues, but the camera is the only way to know for sure. We include the Level 2 scan on every visit, and you see the footage yourself. Call (551) 212-3526 to book one.
Depends what the camera shows. Seam separation on an otherwise sound rigid liner can sometimes be re-seated and banded. Pinholes clustered in one section can be addressed with HeatShield resurfacing. If the host pipe is cracked or the metal gauge has thinned below spec, it’s a replacement. We never recommend a liner replacement without showing you the footage that supports it.
Most liner replacements are done in a day. Partial rebuilds run one to two days. A full rebuild from the roofline up is two to three days, weather permitting. Yonkers winters make masonry work slower, but we’ll give you a clear schedule in the written scope before we start.
Yes. We work with DuraFlex, HeatShield, and Gelco regularly. If you’re not sure what’s in your chimney, that’s what the camera scan is for. We’ll tell you what you have, what condition it’s in, and what your options are, in writing.
If your Copperfield liner or chimney needs attention in Yonkers, call (551) 212-3526 for a free estimate. We’ll put the price in writing, show you the camera footage, and you decide what happens next.
