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.
Fast, Reliable Chimney Repair Across Reading
Chimney repair in Reading almost always comes down to one thing: old masonry meeting Pennsylvania valley weather. Most of the chimneys we open up here were built before 1920, and they show it. Wendell Pike founded Top Hat Chimney in 1999, and his crew has spent nearly three decades pulling spalled brick off Reading rowhouse stacks and relining coal-era clay tile flues that were never meant to vent a modern gas furnace.
If you’re seeing cracked mortar joints, chunks of brick in your gutter, a smokey smell between floors, or water staining on the chimney breast, call (484) 209-0837. We’ll send a sweep to your door, put a camera up the flue, and show you exactly what’s going on before quoting a single dollar.
Key Takeaways:
- Typical mortar repointing in Reading runs $45-$85 per square foot.
- Most rowhouse stacks here contain two to four flues sharing one chase; we identify every flue before any repair begins.
- We offer a free second opinion on any written estimate, and $40 off any repair over $200.
- Every job carries our 90-Day Done Right Promise in writing. If it’s not right, one call brings us back.

Our Chimney Repair Services in Reading
We handle the full scope of Chimney Repair work, but in Reading a few services dominate the call board. The city’s pre-1940 brick rowhouse stock, married party-wall stacks, and valley moisture combine to make mortar repointing, spalling brick repair, waterproofing, and flashing work our bread and butter here.
Mortar Repointing
Reading’s rowhouses were built when lime mortar was standard. A century of freeze-thaw cycles has turned much of it to sand. We rake out the failed joints and tuck in fresh mortar matched to your brick’s color and hardness. Repointing typically runs $45-$85 per square foot in Reading, depending on access and how deep we must grind.

Spalling Brick Repair
Spalling is what happens when water gets into the brick face, freezes, and pops the surface off. Reading’s valley fog and cold air drainage off Blue Mountain make this a constant problem. We can replace individual spalled brick units to match your existing masonry, rather than rebuilding an entire stack that doesn’t need it.

Chimney Waterproofing
We apply a vapor-permeable waterproofing treatment that keeps rain and fog moisture out while still letting the masonry breathe. For Reading’s brick rowhouses, this is often the difference between a chimney that lasts another twenty years and one that starts dropping brick faces after the next hard winter. A typical waterproofing treatment for a two-story rowhouse stack runs $350-$650.

Flashing Repair
Reading is a valley town. When rain drives against a roofline where the chimney meets the shingles, bad flashing is where it gets in. We replace step flashing, counter flashing, and seal the transition so water stops following the brick down into your ceiling. Flashing repair in Reading generally runs $400-$900, depending on the roofline’s pitch and whether we’re working from a ladder or staging.

Wendell and his crew know these systems inside and out, and the 90-Day Done Right Promise covers every one of them.
Common Chimney Repair Problems We See in Reading Homes
- Shared unlabeled flues in a single stack. In Reading’s dense rowhouse blocks it’s routine to find one exterior chimney stack serving three or four appliances: a gas furnace, a water heater, a first-floor fireplace, a second-floor fireplace. Homeowners often don’t know which flue goes to which appliance, and neither does the last guy who worked on it. We map every flue before we touch anything.
- Active appliances venting into blocked or collapsed flues. A legacy of piecemeal coal-to-gas conversions done cheaply in the mid-20th century is that furnaces and water heaters sometimes run their exhaust into a flue that’s now completely bricked off, collapsed, or stuffed with a squirrel nest. You can’t see it from the outside. A camera finds it in ten minutes.
- Cross-contamination between adjacent rowhouses. Shared party-wall chimney stacks mean your neighbor’s flue and your flue may be separated by nothing more than a century-old wythe of brick and crumbling mortar. When a chase cracks or a liner fails, exhaust from one home can migrate into another. This is a genuinely dangerous situation and a frequent repair trigger in Reading.
- Accelerated spalling from valley moisture. Reading sits in a corridor between Blue Mountain and South Mountain. Cold air drains off the ridgelines, valley fog settles in low, and century-old brick absorbs water that later freezes and pops the face off. We see more spalled brick per block in Reading than in almost any market we work.
Pricing for Chimney Repair in Reading, PA
Here are the honest numbers for Reading’s market. Mortar repointing: $45-$85 per square foot. Spalled brick replacement: $60-$120 per brick, depending on size and access. Chimney waterproofing: $350-$650 for a typical two-story rowhouse stack. Flashing repair: $400-$900. Flue relining with DuraFlex stainless: $1,800-$3,400 for a standard one- or two-story rowhouse liner, depending on length and diameter.
What changes the price is access. A stack in the middle of a connected rowhouse block with no alley access means a longer ladder setup or a roof staging system. A freestanding single-family chimney with a walkable roof is simpler. We quote you a flat price before a single tool comes off the truck. The number you hear on the phone is the number on the invoice, no exceptions, and there’s no trip charge inside our service county.
Call (484) 209-0837 for a free estimate. We’ll send a sweep out, scope the flue with a camera, and tell you plainly whether the work can wait or needs doing now.

FAQs - Chimney Repair in Reading
Most homeowners can’t tell, and they shouldn’t have to. In a typical Reading rowhouse stack slotted between party walls, a gas furnace, a water heater, and one or two fireplaces may all empty into a single unlabeled clay-tile chase. The only reliable way to map flues is with a camera inspection from the roof or firebox. It matters because repairing the wrong flue does nothing for your problem. We map every flue before any repair is quoted, and the camera footage gives you a plain-English verdict, every time, no exceptions. Call (484) 209-0837 to schedule an inspection.
Yes, and this is one of the most common issues we see in Reading’s attached housing stock. Shared party-wall stacks mean your flue and your neighbor’s flue run through the same masonry chase. If their liner fails or their mortar joints degrade, exhaust can migrate into your flue through gaps in the party wall. We’ve found carbon monoxide from a neighbor’s furnace venting into an adjacent home’s living space. If you smell exhaust or fuel odors that don’t match your own appliances, or if a CO alarm trips without an obvious source, call us at (484) 209-0837. This is not a wait-and-see situation.
Spalling is caused by water absorbing into the brick face, then freezing and expanding. Reading’s valley location between Blue Mountain and South Mountain traps cold air and fog, driving repeated freeze-thaw cycles into century-old brick. Over time, the brick face pops off. We repair spalling by removing the damaged units and replacing them with matched brick set in compatible mortar, then addressing the moisture source, usually with waterproofing or flashing repair. Small spalls can be patched; big ones mean replacing units. Call (484) 209-0837 and we’ll tell you which one you have.
It’s very common. Many Reading rowhouses still run on original coal-era clay tile liners that were oversized for coal and have since cracked, collapsed, or been partially removed. If the flue serving your gas furnace has no functional liner, you should not keep running the furnace. Modern gas appliances produce exhaust that condenses acidic moisture against unlined masonry, eroding it from the inside and opening pathways for carbon monoxide into your home. We would reline that flue with DuraFlex stainless steel, sized correctly for the appliance, and you’re safe again. Call (484) 209-0837 to have it scoped and quoted.
Once a year, burn or no burn. Chimneys break in the off-season too. Gas furnaces produce acidic condensate that eats at old mortar and clay tile even when you never light a fire. In Reading’s rowhouse stacks, we also want to check for cross-contamination from adjacent flues, animal nesting, and spalling brick that could break loose. A yearly Level 2 camera inspection is cheap compared to what a failed flue in a shared chase can cost. Call (484) 209-0837 to book one; estimates are free.
