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 Coplay
Chimney repair in Coplay comes down to one reality: most of these homes were built between 1880 and 1930 for coal heat, and the flues are now doing a job they were never sized for. That means relining, repointing, and crown work are the norm here, not the exception. Wendell Pike and his crew know exactly what they’re walking into when they park on a Coplay street north of Chestnut or up toward the old cement works. If you need a straight answer about your chimney, call (484) 859-1367 and you’ll get a live person, not a phone tree.
Key Takeaways:
- Most Coplay chimneys are unlined coal-era flues now venting gas or oil appliances, a combination that creates condensation and hidden masonry rot.
- Shared chimney stacks in attached row homes mean a neighbor’s appliance can push flue gases toward your living space.
- Repointing, relining, and crown waterproofing are the three repairs we do most in Coplay.
- Every job gets a 90-Day Done Right Promise, in writing. If it’s not right, one call brings Wendell back.

Our Chimney Repair Services in Coplay
Mortar Repointing & Tuckpointing
Those old brick row homes along Chestnut Street and the streets sloping down toward the Lehigh River take a beating every winter. Freeze-thaw cycles open up mortar joints, and once water gets in, the damage accelerates fast. Repointing in Coplay typically runs $15 to $30 per square foot depending on access and joint depth. We cut out the crumbled mortar and tuck in fresh, matched to the original color so the repair doesn’t scream at you from the sidewalk.

Spalling Brick Repair
Spalling is when brick faces pop off, usually because water soaked in and froze. On Coplay’s compact row homes, spalled bricks don’t just look bad. They compromise the structure of the chimney and can drop chunks onto a narrow sidewalk where kids walk to school. We replace the damaged brick with matched salvaged or new units, and we’ll tell you plainly if the spalling is cosmetic or structural. A typical spalling repair in Coplay runs $400 to $1,200 depending on how many courses are affected and whether we need staging or roof access.

Chimney Waterproofing
Waterproofing is the single best preventive repair for a century-old Coplay chimney. We apply a vapor-permeable sealant that keeps rain and snow out while letting moisture inside the masonry breathe out. The Lehigh Valley climate means sustained wet conditions from November through March, and a waterproofed chimney survives those months far better than a bare brick one. Waterproofing a typical Coplay chimney runs $350 to $700, and we recommend it after any repointing or crown rebuild.

Flashing Repair
The flashing is the metal transition where your chimney meets the roof, and on Coplay’s tight roof pitches it fails more often than people think. Water follows failed flashing into the attic and down into party-wall cavities, damaging both units in attached rows. We replace lead, copper, or galvanized flashing with proper step flashing and counter-flashing, sealed with high-quality roofing mastic. Flashing repair in Coplay generally runs $450 to $950 depending on accessibility and whether the old flashing was installed correctly in the first place.

Trusted Brands We Service in Coplay
We stock and install liners and repair materials from DuraFlex, HeatShield, and Copperfield because we’ve seen them hold up in Pennsylvania winters year after year. When we reline a coal-era flue in Coplay, we size the DuraFlex stainless liner to the current appliance, not the original coal burner. If a flue can be saved without a full reline, HeatShield’s ceramic resurfacing system is often the right call. We keep common components on the truck, which means less waiting on parts and a faster turnaround for Coplay customers.
Common Chimney Repair Problems We See in Coplay Homes
- Oversized coal-era flues choking modern appliances. Coal flues were built big to move hot, dirty coal smoke. Modern gas and oil exhaust is cooler and wetter, so it condenses inside the oversized flue and rots the mortar from the inside out. We see this pattern on block after block near the old cement works.
- Shared chimney stacks spreading trouble between neighbors. In attached rows, your flue and your neighbor’s flue share the same masonry stack. If their high-efficiency appliance vents into a cracked liner, those flue gases can push back into your home through open mortar joints. It’s a carbon monoxide risk that has nothing to do with your own fireplace habits.
- Freeze-thaw cycling shredding century-old mortar. Coplay winters are cold, and the Lehigh Valley geography channels cold air off the river, extending the heating season. Every freeze-thaw cycle wedges moisture deeper into the joints, and the damage compounds year over year.
- Failed flashing on tight street setbacks. Many Coplay streets have houses built close to the curb with steep rooflines and minimal side clearance. Flashing fails, water gets in, and the damage shows up inside both units before anyone sees a leak on the ceiling.

FAQs - Chimney Repair in Coplay
Yes, and this is one of the most common calls we run in Coplay. Attached row homes share masonry chimney stacks, so a deteriorating flue liner or a poorly-vented appliance next door can push flue gases sideways through cracked mortar joints into your home. The camera footage and a plain-English verdict, every time, no exceptions. If you smell exhaust or feel a draft near the chimney wall, call (484) 859-1367 and we’ll inspect it.
Coal-era flues are physically too large and too cold for modern gas appliances, so exhaust gases don’t rise fast enough. They stall, cool, and condense. The condensation eats away mortar from the inside, narrowing the passage further until the appliance can’t push exhaust out at all. That’s when carbon monoxide backs up into the house. The fix is relining the flue to match the current appliance. Call (484) 859-1367 for a camera inspection and an honest assessment.
Once a year, burn or no burn. Chimneys break in the off-season too. For unlined or vintage chimneys in Coplay, we recommend a Level 2 camera inspection every year rather than a visual-only sweep, because the damage we’re looking for is inside the flue, not on the surface. Freeze-thaw cycles do their work in the winter, and by spring you may have spalled bricks or cracked crowns you can’t see from the ground. Call (484) 859-1367 to schedule an annual inspection before the heating season.
Mortar repointing combined with flue relining. The homes near the river get the worst of the cold air channeling off the water, which means more freeze-thaw cycling and more condensation inside those oversized coal-era flues. We rarely see a single isolated repair. It’s usually a combination: repoint the mortar, reline the flue, rebuild the crown, and waterproof. Call (484) 859-1367 and we’ll walk you through what your chimney actually needs and what can wait.
Yes, but it takes a crew that knows how to work tight. On a brick row house off Chestnut Street, our tech found a shared chimney stack with a neighbor’s vented appliance pushing flue gases past a cracked liner into an unlined coal-era flue. After a Level 2 inspection showed spalling and a dangerously weak draft, we rebuilt the crown, repointed the mortar joints, and relined the flue with a DuraFlex stainless liner sized for the current gas furnace, then flashed the roof penetration to stop cross-contamination from the adjacent property. Tight setbacks require careful staging and a two-person crew, but it’s work we do regularly in Coplay. Call (484) 859-1367 and we’ll come out and take a look.
If you’re in Coplay and you’re wondering whether your chimney needs work, the answer is a phone call away. We’ll send a sweep who knows this borough’s housing stock, we’ll put a camera in the flue, and we’ll tell you straight what’s wrong and what isn’t. No scare tactics, no invented problems. Call (484) 859-1367 today and get a free estimate from a name you can verify.
