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.

We’ve been working the chimneys of Emmaus for decades. Russell Haines and our crew know the borough’s streets - from the tight rows near Main Street to the late-Victorian detached homes off Chestnut and the brick semis along Ridge. Dispatch and scheduling are coordinated from our Philadelphia office, but our trucks are on Emmaus roads daily. We understand the coal-conversion legacy that defines this borough’s chimneys: original clay tiles sized for high-BTU coal combustion, now venting low-temp gas appliances into flues three times too large. That mismatch creates condensation problems you can’t see from the living room. We find them with a camera, show you the footage, and size the fix to the appliance - not the other way around.

We know Emmaus’s specific conditions: the freeze-thaw cycling that crosses 32°F dozens of times each Lehigh Valley winter, the hard Portland cement repointing from the 1970s that looks solid but traps moisture, the coal-era flues now venting gas furnaces on block after block. That local knowledge changes what we look for and how we fix it.
Our Chimney Liner & Rebuild Services in Emmaus
Stainless Steel Liner Installation
Stainless steel is the standard for relining Emmaus’s oversized coal-era flues. We use DuraFlex and Olympia Chimney products, matched precisely to your appliance’s BTU output and venting temperature. A gas furnace venting into a clay tile built for coal drops exhaust temperature below the dew point, and that acidic condensation eats lime-mortar joints from the inside. We’ve replaced dozens of these in Emmaus’s historic core. A typical stainless liner installation in Emmaus runs $1,800-$3,400, including the Level-2 inspection and camera documentation.

Flexible Liner Solutions
Emmaus’s older chimneys often have offsets, corbels, or tight cleanout chambers that rigid pipe can’t navigate. Flexible liners from DuraFlex solve that. They’re especially useful in the borough’s semi-detached homes where the flue path was never straight to begin with. Our Chimney Liner & Rebuild team measures the run with a camera first, then specifies the right diameter and alloy for your fuel type. Flexible liner installations in Emmaus typically fall between $1,600 and $2,900.

Liner Replacement
This is the defining service in Emmaus. The borough’s coal-conversion legacy means countless chimneys had their coal grates swapped for oil and later gas furnaces without ever resizing the flue - so the round vent now sits inside a rectangular coal-era tile that’s three times too big, dropping exhaust temperature and dumping acidic condensation straight into 80-120 year old lime mortar. That mismatch, block by block in a compact walkable borough, is why relining here is a sizing problem, not just an age problem. We remove the failed clay tile, inspect the masonry shell with a camera, and install a liner sized to your appliance’s actual output. Liner replacement in Emmaus ranges from $1,800-$3,400 for standard gas furnace applications.

Partial Rebuild
When the flue is sound but the exterior masonry has failed, partial rebuild is the right call. In Emmaus, we see this constantly: hard Portland cement repointing from the 1970s or 80s that looks intact from the roof but traps water against softer original brick, accelerating face spalling while hiding void channels only visible from inside the flue. On a late-Victorian detached on the 200 block of Norden Alley, our tech dropped a DuraFlex camera and found the original clay tiles cracked the length of the run and a 1970s hard Portland repoint trapping moisture on the exterior wythe - spalling brick visible from the yard, hidden void channels behind the patch. We documented every crack on the homeowner’s screen before quoting, then installed a properly sized stainless liner matched to their gas furnace’s low-temp exhaust and rebuilt the crown to shed water away from the lime mortar. The homeowner made the call on the repair with the footage in front of them, not our word. Partial rebuilds in Emmaus typically run $2,200-$5,500.

Common Chimney Liner & Rebuild Problems We See in Emmaus Homes
- Gas furnace vented into an oversized coal-era clay tile. The flue was built for high-BTU coal combustion, not low-temperature gas exhaust. Condensation forms, turns acidic, and eats lime-mortar joints from inside the flue - invisible until a Level 2 inspection with camera reveals the damage. We find this on Emmaus’s older streets every season.
- Hard Portland cement repointing from the 1970s-80s. It looks intact from the roof but traps water against softer original brick, accelerating face spalling while hiding void channels only visible from inside the flue. A camera inspection shows what the roofline hides.
- Freeze-thaw cycling across the Lehigh Valley. Temperatures cross 32°F dozens of times each winter, spalling exposed brick and crown, letting water infiltrate the flue. Annual cleaning sweeps on Emmaus’s older rooflines routinely flag this progressive damage.
- Crown deterioration letting water into the flue system. Emmaus’s pre-WWII chimneys were built with lime-mortar crowns that erode faster than modern concrete. Once the crown fails, water runs down the flue wall, accelerating liner and mortar decay from the top down.

FAQs - Chimney Liner & Rebuild in Emmaus
You almost certainly need a properly sized liner. The original clay tile in Emmaus’s coal-era homes was built for high-BTU combustion at temperatures that kept flue gases above the dew point. Your gas furnace produces cooler, wetter exhaust that condenses inside that oversized flue, turning acidic and destroying mortar joints from within. The clay tile itself may look fine from the bottom. Only a Level-2 camera inspection shows the actual condition. Call (610) 991-8179 to schedule - estimates are free.
For liner and rebuild questions, you need a Level-2 inspection. We run a camera the full length of the flue, photograph every joint, crack, and condensation stain, then show you the footage on a screen with a plain-English explanation of what we’re seeing. The inspection includes the exterior masonry, crown, and appliance connection. Level-2 inspections in Emmaus run $199-$289. Nothing is recommended without camera evidence you can see for yourself.
Three factors converge here: lime-mortar construction from the 1890s-1940s that’s now 80-120 years old; hard Portland cement repointing from the 1970s-80s that traps moisture against softer original brick; and the Lehigh Valley’s repeated freeze-thaw cycling that exploits every weak point. Newer suburbs built after 1960 with Portland mortar and straighter flue designs don’t face this stacked set of problems. Emmaus’s compact, walkable borough layout just means you see it house after house, block by block.
We show you the camera footage before we quote any repair. On that Norden Alley job, the homeowner watched us document cracked tiles and hidden void channels in real time, then made the call with the evidence in front of them. If your flue is sound and properly sized, we’ll tell you. We’ve told plenty of Emmaus homeowners their chimney needs nothing more than a sweep and a water-repellent treatment. The 90-Day Done Right Promise means we have to stand behind whatever we recommend - so we only recommend what we can prove. Call (610) 991-8179 if you want a second opinion on any written estimate; ours is free.
Partial rebuild addresses the crown, upper courses, and sometimes the shoulders of the chimney - the parts most exposed to weather and freeze-thaw damage. The flue itself stays in place or gets relined. Full rebuild means the chimney is taken down to the roofline or below and reconstructed, necessary when the structural wythes are compromised or the footing has failed. In Emmaus’s historic core, we more often see partial rebuilds paired with liner replacement: the masonry above the roof is rebuilt with proper crown drainage, while a new stainless liner handles the venting. Full rebuilds are less common but critical when the chimney leans or shows major structural cracking. We’ll tell you which category you’re in, and show you why. Call (610) 991-8179 for an exact quote - estimates are free.
