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.

AfterFast, Reliable Chimney Liner & Rebuild Across Upper Nazareth
Chimney liner and rebuild work in Upper Nazareth, PA typically runs $850-$3,800 depending on whether you need a liner replacement alone or a partial rebuild of the chase and firebox. Most jobs are completed in one to two days once we’ve inspected the system and ordered any manufacturer-specific parts. If you live in Upper Nazareth and your prefab fireplace is from the 1990s or early 2000s, you’re probably not dealing with a brick chimney at all, and that changes what a liner inspection and rebuild actually means for your home. Call (484) 859-1367 and Wendell or one of his crew will walk you through what you’re looking at.
We’ve been crawling through fireplaces and chases across the Lehigh Valley long enough to know that Upper Nazareth’s housing stock has its own set of problems. The subdivisions that went up fast between 1990 and 2010 left behind thousands of factory-built fireplaces wrapped in wood-framed chases, and those systems are hitting the age where liners delaminate, chase covers rust through, and refractory panels crack. Most homeowners never know until someone actually opens the firebox and looks.
Why Top Hat Chimney Is Upper Nazareth’s Preferred Chimney Liner & Rebuild Company
Wendell Pike started Top Hat Chimney in 1999, and he’s still the one answering the phone most days. That matters in Upper Nazareth because the work here isn’t textbook masonry repair. It’s knowing which zero-clearance fireplace brands were installed in which subdivisions, what their manufacturer-specific liner requirements are, and how Blue Mountain’s freeze-thaw cycles punish a builder-grade chase cover. A franchise crew that rotated in last spring won’t know that a 2002 colonial in Valley View Estates likely has the same rusted chase cover as the house three doors down.
Every job we finish in Upper Nazareth carries the 90-Day Done Right Promise in writing. If something isn’t right, one call brings Wendell back. No arguing, no re-quote. Our Chimney Liner & Rebuild team shows up in uniform, background-checked, with a real arrival window and a call if that window slips. Ask anyone on your street. We’ve probably been in their fireplace.
We also don’t play the price-swap game. The number you hear on the phone is the number on the invoice. A free second opinion on any written estimate from another company is part of how we work, because if you’re being told you need a $4,000 rebuild, you should be able to see the camera footage that proves it.
Our Chimney Liner & Rebuild Services in Upper Nazareth
Stainless Steel Liner
A stainless liner is the standard fix when the original clay tile or flexible aluminum liner in an Upper Nazareth home has cracked, delaminated, or separated. We install DuraFlex stainless systems sized to the original zero-clearance fireplace, not whatever is on the truck. In a prefab chase, the liner has to match the manufacturer’s listing requirements, and that’s where a lot of generic chimney companies get it wrong. A stainless liner replacement in Upper Nazareth runs $1,200-$2,800 installed.
Flexible Liner
Flexible liners make sense when the existing flue takes a turn or when you’re relining a masonry chimney at an older farmstead on the edge of the township. But flexible doesn’t mean flimsy. We use DuraFlex and Copperfield products that hold up to the freeze-thaw cycling that Upper Nazareth gets every winter. If your old Hairpin-style liner has delaminated and is flaking into the firebox, that’s a replacement, not a patch job. Flexible liner work in Upper Nazareth typically runs $1,100-$2,600.
Liner Replacement
This is the service we do most for Upper Nazareth’s 1990s-2010s tract homes. The original builder-installed liner fails, and the homeowner usually finds out because of a smoking fireplace, a draft smell in the house, or visible rust flakes in the firebox. We pull the old liner, document the condition with camera footage, and install a properly sized replacement. Liner replacement in Upper Nazareth averages $1,300-$2,900, including the inspection and camera report.
Partial Rebuild
A partial rebuild in Upper Nazareth usually means one of two things. Either the wood framing inside the chase has rot from a rusted chase cover and needs repair before a new liner goes in, or the firebox itself has cracked refractory panels and a damaged smoke shelf that needs rebuilding. In a prefab system, you can’t just mortar over it. The manufacturer’s parts have to be ordered and installed to spec. Partial rebuilds in Upper Nazareth run $2,000-$3,800 depending on how deep the damage goes.

Trusted Brands We Service in Upper Nazareth
We install and service liners and components from DuraFlex, Copperfield, HeatShield, and Gelco. That matters because a prefab fireplace in Upper Nazareth is built around a specific manufacturer’s listed parts. You can’t swap a liner from one brand into a firebox from another and call it safe. We keep common replacement components for the brands most prevalent in Upper Nazareth’s subdivisions on hand or within a day’s turnaround, which means less waiting between diagnosis and repair. When your chase cover has been rusting since 2005, another two weeks of waiting isn’t harmless.
Common Chimney Liner & Rebuild Problems We See in Upper Nazareth Homes
- Rusted builder-grade chase covers. The galvanized covers installed on 1990s-2000s prefab chases across Upper Nazareth rarely last 20 years. Once the corners rust through, rain and snowmelt run straight down into the wood framing. By the time the liner is checked, the chase may have been rotting silently for years.
- Cracked refractory panels in zero-clearance fireplaces. Same subdivision era, same problem. Panels crack from heat cycling and no longer shield the surrounding wood chase. The chimney looks fine from outside. The firebox tells a different story once you actually look at it.
- Warped or missing chimney caps on prefab terminations. Animals get in, debris blocks draft, and creosote collects inside the liner. In a flexible liner, that creosote accumulation becomes a fire hazard quickly because the liner’s thinner than a solid masonry flue.
- Delaminated flexible liners from freeze-thaw cycling. Blue Mountain’s cold winters and the 30-35 inches of annual snowfall Upper Nazareth gets mean expansion and contraction every single season. Hairpin-style liners installed in the early 2000s are failing now, neighborhood by neighborhood.
Pricing for Chimney Liner & Rebuild in Upper Nazareth, PA

FAQs - Chimney Liner & Rebuild in Upper Nazareth
Yes, and honestly you need it more than the brick-chimney house down the road. Upper Nazareth’s tract-built homes from that era use factory-built, zero-clearance fireplaces with flexible liners inside wood-framed chases. The liner isn’t protected by masonry. It’s protected by a sheet-metal chase cover that rusts, and once that fails, water gets into the wood framing around the liner. Visual inspection from outside tells you nothing because the liner is hidden behind vinyl siding and framing. We need to open the firebox and run a camera up. Call (484) 859-1367 and we’ll schedule it.
Because the builder installed the same cheap galvanized covers on every house when those subdivisions went up, and Upper Nazareth’s winters with Blue Mountain to the north produce exactly the freeze-thaw cycling that eats galvanized steel. Twenty years of that, and the corners go first, then the seams. Walk a street in Valley View Estates in 2026 and you can almost predict which houses need covers by their age and exposure. The one we opened on a 2002 colonial had the cover rusted through at all four corners and a liner that had delaminated from years of moisture. That work would have gone unnoticed without a Level 2 inspection. Call us if your chase is showing rust stains or you’re seeing water near the fireplace. A new stainless cover is cheap compared to the framing rot it prevents.
Often, yes. If the framing is still sound, we pull the old cover, replace any rusted flashing, install a stainless chase cover, and run a new liner sized to your zero-clearance firebox. The camera report shows what’s actually needed. We don’t rebuild a chase that doesn’t need rebuilding. If rot has gotten into the framing, that’s different, and you’ll see it on the screen before we do anything. Call (484) 859-1367 for an exact quote. The estimate is free.
Yes, if you ever plan to use it again or if you’re selling the house. A fireplace that hasn’t been used isn’t the same as a safe fireplace. In Upper Nazareth’s 1990s-era prefabs, the refractory panels have been heat-cycling since installation and can crack even when the firebox sits cold. The chase cover may have been rusting for a decade while the fireplace collected dust. When you go to sell, a home inspector will flag the fireplace anyway. Better to know now. Once a year, burn or no burn. Chimneys break in the off-season too. Call (484) 859-1367 and we’ll get it inspected before burning season starts.
We install DuraFlex stainless liners, Copperfield flexible liners, and HeatShield repair systems. For prefab fireplaces, the liner has to be listed for use with your specific firebox. We check the manufacturer’s tag inside the firebox door and match the liner accordingly. If your fireplace has no tag or it’s illegible, we verify the make and model through other means before ordering. The camera footage and a plain-English verdict, every time, no exceptions. We never install a liner that isn’t right for the firebox, because that’s how you get a chase fire instead of a fireplace fire. Call (484) 859-1367 with your fireplace make and model if you know it, and we’ll get you scheduled.
