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.

AfterTrusted Chimney Liner & Rebuild for Pottstown Homeowners
A chimney liner and rebuild in Pottstown typically costs between $1,800 for a straightforward stainless steel liner installation and $8,500 or more for a full chimney rebuild, with most projects completed in a single day or scheduled within the week. Hearthstone Chimney Co. has been serving Pottstown homeowners since 1984, and we document every condition with a Level-2 camera inspection so you see exactly what we see before any work begins. Call (610) 819-4281 - a live person answers 24 hours a day, seven days a week.
We’ve worked on chimneys in every era of Pottstown housing, from the stone farmhouses near Ringing Rocks to the post-war colonials in Lower Pottsgrove and the newer developments around Sanatoga. The clay liners in homes built before 1980 are reaching the end of their service life, and the freeze-thaw cycles of southeastern Pennsylvania winters accelerate mortar deterioration in brick and block chimneys. When a liner fails or a chimney structure degrades, the risks are real: carbon monoxide intrusion, chimney fires from creosote buildup in compromised flues, and water damage that compounds every season it is not addressed.
Russell Haines founded Hearthstone Chimney Co. on the principle that a homeowner deserves to understand their chimney in plain English and to receive a fair price that does not change once the work begins. Our 90-Day Done Right Promise - in writing, no arguing - means if something is not right, we come back. No paperwork shuffle, no finger-pointing. That is the Keystone Standard we have upheld for over 42 years.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner Installation
A stainless steel liner is a continuous, corrosion-resistant flue pipe that protects your chimney walls from heat and corrosive byproducts. In Pottstown, we recommend stainless steel liners for oil and gas appliances especially, because the sulfur in these fuels eats clay tile over decades. We size every liner to the appliance using NFPA 211 standards, and we source our stainless steel from Olympia Chimney and Gelco - brands we have installed in hundreds of local homes with zero callbacks for material failure.
Flexible Liner Installation
Flexible liners navigate offset flues and chimney bends that rigid pipe cannot follow, making them essential for many Pottstown chimneys built with offsets to avoid floor joists. We use DuraFlex and Olympia Chimney flexible products rated for the specific appliance - wood, gas, or oil - because a liner rated for gas will fail prematurely in a wood-burning application. Our technicians measure the flue path with a video camera before ordering material, so the liner arrives cut to length with no field splicing that creates weak points.
Liner Replacement
When a clay tile liner cracks, spalls, or separates at the joints, replacement is the only code-compliant option - patching with refractory cement is a temporary fix that inspectors in Montgomery County and Chester County will flag. We extract the damaged liner when possible, or we install a new stainless or flexible liner inside the existing flue if the chimney structure is sound. Every replacement includes a smoke test and camera verification before we call the job complete, and you receive photos of the new liner from top to bottom.
Partial Chimney Rebuild
A partial rebuild addresses the most weather-exposed section of a chimney, typically the top four to six courses above the roofline where freeze-thaw damage concentrates. In Gilbertsville chimney liner and rebuild projects and across Pottstown’s climate, we see this damage accelerate on chimneys with failed crowns or missing caps, because water saturates the brick and spalls the face off in winter. We match existing brick and mortar color where possible, rebuild to current code height requirements, and install a poured concrete crown with proper drip edge and overhang to protect the new work.
Full Chimney Rebuild
A full rebuild is necessary when the chimney structure is compromised from the foundation up - leaning, significant mortar loss, or internal collapse that makes liner installation unsafe. We have completed Boyertown chimney liner and rebuild projects on historic homes in Boyertown and West Pikeland where the original chimney was built without proper footings or with salvaged brick that could not withstand modern heating appliance temperatures. Our process includes temporary venting for your heating system, staged demolition, footing inspection, and reconstruction with new brick or block, a properly sized flue, and a crown and cap assembly that will outlast the next generation of ownership.
Liner Repair
Some liners can be repaired rather than replaced, particularly when the damage is localized to a few cracked tiles or minor joint gaps. We use HeatShield cerfractory sealant for select applications, applied with a specialized foam applicator that fills voids and creates a smooth, insulated flue surface. This is not a universal solution - we will show you the camera footage and explain exactly where HeatShield is appropriate and where it would be a false economy. When we recommend repair over replacement, you will know why. When we recommend replacement, you will know that too.

Brands We Service for Chimney Liner & Rebuild
We work exclusively with professional-grade materials from manufacturers who stand behind their products the way we stand behind our work. Our technicians are trained and equipped to install and service Gelco stainless steel liners, which we have used in Pottstown and Royersford homes for over fifteen years with consistent performance in high-heat wood-burning applications. Olympia Chimney supplies both rigid and flexible liners we specify for gas and oil conversions, and we maintain inventory of their common diameters so most installations proceed without material delays. Famco and Copperfield provide the caps, dampers, and specialty fittings that complete a liner system, and we source their components to ensure compatibility and warranty coverage.
We have also installed and serviced HeatShield resurfacing systems and DuraFlex flexible liners in hundreds of chimneys across Montgomery and Chester counties. Whether your existing liner is one of these brands or another make, we can assess its condition, determine if it is suitable for continued use, and install a replacement that meets or exceeds the original specification. We do not use builder-grade substitutes or generic parts that compromise the system we are putting our name on.
Signs You Need Chimney Liner & Rebuild Right Now
- White efflorescence or spalling brick on the exterior. These are signs that water is migrating through the masonry and freezing, which expands and fractures the brick face. In Pottstown, this accelerates after wet winters like 2023-2024, and it indicates the chimney structure is absorbing moisture rather than shedding it. Left unaddressed, the damage moves inward and compromises the flue.
- Flakes of clay tile in the firebox or cleanout. These shards are pieces of your liner that have detached due to thermal shock, age, or chimney fire damage. A liner that is shedding material has lost its containment integrity, which means heat and combustion gases can reach combustible framing. This is not a maintenance item for next season - it is a safety condition that warrants immediate inspection.
- Smoke or odors entering living spaces when the system operates. This indicates a breach in the flue or a blockage that is forcing exhaust into the home. Carbon monoxide is odorless and can accompany visible smoke, so any odor event merits a Level-2 inspection with camera documentation to locate the exact point of failure.
- Visible cracks in the chimney crown or missing mortar joints. The crown is your chimney’s umbrella, and when it fails, water enters the core of the masonry. We see this most often on chimneys in Sanatoga and Gilbertsville where the original crown was a thin mortar wash rather than a proper poured concrete cap. Water infiltration from above destroys liners from the outside in.
- Your heating appliance was upgraded but the liner was not. Modern high-efficiency furnaces and boilers produce cooler exhaust that condenses into acidic moisture inside an oversized flue. If your furnace was replaced in the last decade but the liner was never evaluated, it may be deteriorating from condensate damage you cannot see until the camera goes up.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Schedule and confirm. When you call (610) 819-4281, a live person answers and books your appointment at a time that works for you. We confirm by phone the day before, and our technician arrives in a marked vehicle, in uniform, within the agreed window. No four-hour waits, no mystery contractors.
- 2
Level-2 camera inspection and documentation. We insert a high-resolution video camera the full length of the flue, recording every surface. You see the footage in real time, and we explain what we are observing - cracked tiles, joint gaps, creosote buildup, water damage, or structural concerns. The inspection produces dated photos and a written condition report.
- 3
Plain-English verdict and upfront pricing. Russell Haines insists that every homeowner receive a clear diagnosis before any work is proposed. We explain whether your chimney needs a liner repair, liner replacement, partial rebuild, or full rebuild, and we provide a written estimate with line-item pricing. The number on the estimate is the number on the invoice. We do not “find” additional problems once work begins.
- 4
Professional installation with quality materials. Our technicians install your liner or rebuild using the materials specified in your estimate - Gelco, Olympia Chimney, HeatShield, or other professional-grade products. Most liner installations and partial rebuilds are completed in a single visit. Full rebuilds are staged with temporary heating system venting so you are never without heat.
- 5
Final verification, cleanup, and written guarantee. We perform a post-installation camera inspection and smoke test to confirm proper draft and containment. The work area is cleaned, your furniture is protected throughout, and you receive a written invoice, the inspection report, and our 90-Day Done Right Promise - in writing, no arguing. If it is not right, we come back.
How Much Does Chimney Liner & Rebuild Cost in Pottstown?
A typical stainless steel liner installation in Pottstown runs $1,800-$3,400 for a straightforward single-flue application, while a flexible liner in a chimney with offsets or bends ranges from $2,200-$4,100. Liner replacement where we must extract damaged clay tile first adds $400-$800 for labor and disposal. Partial rebuilds above the roofline generally fall between $2,800-$5,500 depending on height, brick matching requirements, and whether the crown and cap need replacement. Full chimney rebuilds start around $6,500 and can exceed $12,000 for multi-flue structures on historic homes with specialty materials.
Several factors move these numbers. The flue diameter and length determine liner material cost - a 6-inch by 25-foot run uses less material than an 8-inch by 35-foot run. Accessibility matters: chimneys on steep roofs or behind additions require additional safety setup. The condition of the existing structure affects whether we can line in place or must rebuild first. And the appliance type - wood, gas, oil, or pellet - dictates the liner rating and insulation requirements.
