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.

Hearthstone Chimney Co. has been repairing chimneys in Pottstown and the surrounding communities for over 42 years, and our background-checked, uniformed technicians complete most jobs in a single visit with no-hassle upfront pricing. Call (610) 819-4281 anytime - a live person answers 24 hours a day, 7 days a week.
We’ve worked on chimneys in every corner of Pottstown, from the historic homes near High Street to the brick colonials in Lower Pottsgrove and the ranch-style houses out toward Sanatoga. The freeze-thaw cycles here in Montgomery County are hard on masonry. Water gets into hairline cracks, winter turns it to ice, and by spring you’ve got spalling brick, crumbling mortar, or worse. We’ve seen it all, and we fix it right the first time. Every repair we make is backed by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back and make it right. That’s the Keystone Standard we’ve lived by since 1984.
Russell Haines built this company on a simple idea: treat every chimney like it’s your own, document what you find, and stand behind the work. No shortcuts, no surprises on the bill, no disappearing after the check clears. When you call Hearthstone, you get a square deal. We’ll be there when we say.
What Our Chimney Repair Service Includes
Mortar Repointing
Mortar repointing is the process of grinding out deteriorated mortar between bricks and packing fresh, matched mortar into the joints. In Pottstown, we see this need most often in homes built before 1980 where the original lime mortar has simply worn away from decades of weather exposure. Our technicians use professional-grade mortar mixes formulated for our local climate, not the cheap bagged stuff from the hardware store, and we color-match so the repair blends with your existing brickwork.
Spalling Brick Repair
Spalling happens when water-saturated bricks freeze and the face of the brick flakes or pops off entirely. It’s common on Pottstown chimneys that lack proper caps or where the crown has cracked, especially on north-facing exposures that stay wet longer. We remove and replace spalled bricks with matching units, then identify and fix the source of the water intrusion so it doesn’t happen again next winter.
Chimney Waterproofing
Waterproofing isn’t a cosmetic treatment - it’s a breathable silane/siloxane sealant that keeps liquid water out while letting water vapor escape. We apply this to sound masonry chimneys in Pottstown after any needed repairs are complete, using professional-grade formulations from Copperfield. It’s particularly valuable for homes in West Pottsgrove and Stowe where wind-driven rain hits chimneys harder. Done correctly, it extends the life of your masonry by a decade or more.
Flashing Repair
Flashing is the sheet metal where your chimney meets the roof, and it’s the single most common leak point we find in Pottstown inspections. The original step flashing may have corroded, the counterflashing may have pulled away, or a previous roofer may have tried to seal it with caulk that has long since failed. We fabricate and install custom flashing using proper techniques - not sealant shortcuts - and we document the before and after with photos you can see.
Chimney Rebuilding
When damage is too extensive for spot repairs, partial or full chimney rebuilding is the only safe option. We’ve rebuilt chimneys in Pottstown neighborhoods from Cedarville to Ringing Rocks where the structure had deteriorated to the point of leaning, separating from the house, or posing a collapse risk. Our rebuilds use matching brick and proper engineering, with a plain-English verdict upfront so you understand exactly why rebuilding is necessary and what it will cost before we start.
Tuckpointing
Tuckpointing is a specialized form of repointing where we cut narrow grooves into the mortar joints and fill them with a contrasting color to create the appearance of fine, precise joints. It’s often requested for historic homes in Pottstown’s older districts where architectural authenticity matters. Our craftsmen have the hand skills this work demands, and we take the time to get the color and profile right - because on a 1920s Colonial, “close enough” isn’t.

Brands We Service for Chimney Repair
We work exclusively with professional-grade materials from industry-trusted manufacturers - no builder-grade substitutes that fail in five years. For chimney liners and components, we regularly install and repair DuraFlex and Olympia Chimney systems, and we stock common parts so most repairs don’t wait on shipping. We’ve serviced hundreds of Gelco chimney caps and Famco venting products over the decades, and we know their specifications well enough to spot when a previous installer used the wrong component for the application.
Our waterproofing and refractory work relies on HeatShield and Copperfield materials - the same products specified by engineers for commercial installations. Whether you have a Gelco cap, an Olympia Chimney liner, or any other make, we can help. We don’t push one brand over another; we recommend what fits your chimney, your budget, and how long you plan to stay in your home.
Signs You Need Chimney Repair Right Now
- White staining (efflorescence) on your brick. That chalky white deposit is minerals left behind when water moves through your masonry and evaporates. It means water is getting in, and it’s only a matter of time before the freeze-thaw damage starts. In Pottstown’s climate, we’ve seen efflorescence in February turn to spalling brick by the following November.
- Cracked or missing mortar joints. Gaps in your mortar let water penetrate directly to the interior structure. Once water reaches the flue liner or the wooden framing adjacent to the chimney, you’re looking at repairs that go far beyond tuckpointing. We catch this regularly during camera inspections in homes near the Schuylkill River where humidity runs higher.
- Your chimney crown is cracked or crumbling. The crown is the concrete cap that sheds water away from the flue. When it fails, water pours directly down into the chimney structure. We’ve replaced crowns in Pottstown homes where the damage was invisible from the ground but had rotted the adjacent roof sheathing.
- Rust stains on the exterior or in the firebox. Rust means moisture is reacting with metal components - usually the damper, fire grate, or a deteriorating liner. Left unchecked, a rusted liner can develop gaps that allow heat and combustion gases into wall cavities. This is not a “wait and see” situation.
- The chimney is leaning or separating from the house. A tilting chimney indicates foundation settlement, deteriorated footing, or structural failure of the masonry itself. It’s a safety hazard that can progress suddenly. We’ve stabilized and rebuilt leaning chimneys in Sanatoga and Gilbertsville where homeowners thought the slight lean had been there for years - until it wasn’t slight anymore.

No jargon, no scare tactics.

Upfront estimate with line-item pricing. Before any work begins, you receive a written estimate with each repair itemized and priced. The number on the estimate is the number on the invoice.

How Much Does Chimney Repair Cost in Pottstown?
How much chimney repair costs in Pottstown varies with the scope of damage, access difficulty, and materials required. Here’s what we typically see in our local market:
- Mortar repointing (partial): $450-$1,200 for a section of chimney, depending on height and accessibility
- Full chimney repointing: $1,800-$3,500 for a standard two-story chimney
- Spalling brick repair (spot): $350-$900 per area, plus any underlying water source repair
- Chimney crown repair or rebuild: $600-$1,500 for standard concrete crowns; precast or custom-formed may run higher
- Flashing repair: $400-$950 for typical step and counterflashing replacement
- Chimney waterproofing treatment: $250-$600 depending on chimney size and condition
- Partial chimney rebuild: $2,500-$5,500
- Full chimney rebuild: $4,500-$12,000+ depending on height, brick matching requirements, and liner needs
Several factors push these numbers up or down. A chimney on a steep roof in West Pikeland costs more to access safely than one on a single-story ranch in Stowe. Historic brick that requires special ordering adds material cost and time. Hidden damage - rotted framing behind the chimney, for example - can’t be priced until it’s exposed, which is why we insist on camera inspection before quoting.
The best way to avoid overpaying is to get a detailed, written estimate from a company that shows you the problem, not just tells you about it. Be wary of anyone who quotes a repair price from the ground without inspecting the interior flue. We’ve provided free second opinions on written estimates from other contractors, and we’ve found that the lowest bid often omits necessary steps that become “change orders” later. Our price is our price. A square deal: no surprises on the bill.
Every estimate from Hearthstone Chimney Co. includes the inspection, photos, written verdict, and itemized pricing. Call (610) 819-4281 for your free estimate - there’s no obligation to proceed.
