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 worked on enough chimneys in Nazareth to know the borough’s older housing stock isn’t like the surrounding townships. The historic core near Center Square is packed with 1880s-1920s brick and frame homes built during the coal era, many still carrying their original multi-flue masonry stacks. One flue served the parlor fireplace. Another served the coal furnace. When owners converted to oil or gas in the 1950s and 60s, that second flue often got an improvised cap, a sheet metal scrap, a broken clay tile piece, sometimes plywood. Decades later, a new owner installs a wood stove or gas insert into the fireplace flue, never knowing the adjacent flue is blocked. That’s not a theoretical problem here. We find it regularly.
Our Fireplace Services team treats every Nazareth chimney with the assumption that its history matters to its safety. We don’t brush and run. We camera-inspect, document what we find, and show you the photos before recommending anything.

Why Hearthstone Chimney Co. Is Nazareth’s Preferred Fireplace Services Company
Hearthstone Chimney Co. has served local Pennsylvania communities for over 42 years, and our crews know the Lehigh Valley’s older housing stock from Bethlehem to Bath. Nazareth’s borough-center homes present a specific challenge: shared multi-flue stacks with one active flue and one orphaned, often improperly capped flue from a mid-century conversion. A sweep who doesn’t camera-check both flues in that stack is missing the hazard.
We answer every call with a live person, 24 hours a day, 7 days a week. No voicemail, no callback queue. Our technicians are background-checked, uniformed, and carry professional-grade materials from DuraFlex, HeatShield, and Gelco. Most jobs finish in one visit. Our pricing is upfront: the number on the estimate is the number on the invoice.
Every job carries our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back. That’s the Keystone Standard, and it’s governed by our K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.
We coordinate scheduling from our Philadelphia office, but our Nazareth customers get local crews who understand the freeze-thaw damage that hits exposed masonry in this part of the Lehigh Valley, where 30-35 inches of annual snow and sharp late-winter temperature swings aggressively spall mortar crowns and joints.
Our Fireplace Services in Nazareth
Gas Fireplace Service
Gas fireplaces in Nazareth need annual inspection of the burner assembly, pilot system, and venting path. In older borough homes where a gas insert was retrofitted into a coal-era flue, we verify that the liner is properly sized and that no blocked secondary flue is creating a backdraft hazard. Our techs clean burner ports, check gas pressure, and test CO levels. We service inserts from major manufacturers and stock replacement parts to avoid ordering delays.

Wood Burning Fireplace
Nazareth’s original parlor fireplaces were built for coal grates and later adapted for wood. The flues are often oversized by modern standards, which sounds harmless but produces sluggish draft and accelerated creosote buildup. A standard brush cleaning without camera inspection can’t tell you if the clay tiles are cracked or if last spring’s freeze-thaw cycle loosened mortar that’s now sitting on the smoke shelf. We document everything with photos and a plain-English verdict.

Fireplace Insert
Inserts are popular in Nazareth’s older homes because they squeeze modern efficiency into a historic opening. But the connection matters. An insert vented into an unlined or improperly lined flue is a code violation and a fire hazard. We see too many installations where the liner was never properly connected to the insert collar, or where the installer never checked the capped coal flue sharing the same stack. Our Level 2 camera inspection catches these before they become problems. We install and service inserts with DuraFlex liners sized to the appliance, not the old flue.

Damper Repair
A stuck or rusted damper wastes heat and can admit downdrafts. In Nazareth’s humid summers and freeze-thaw winters, cast-iron throat dampers corrode and masonry-top dampers seize. We repair or replace both types, and we’ll show you the mechanism working on camera before we leave. If the damper is beyond repair, we can install a lock-top or Lyemance damper that seals better than the original.

Firebox Repair
The firebox takes the direct heat, and in Nazareth’s century-old homes the refractory panels or brick lining often show cracks, spalling, or deteriorated mortar. Spring rains flush loosened crown mortar down the flue and into the firebox, accelerating damage. We repair with HeatShield refractory mortar or replace panels as needed, matching the original construction. No recommendation without photo evidence.

Fireplace Conversion
Converting a wood-burning fireplace to gas in Nazareth requires more than running a line and dropping in a log set. The flue must be evaluated for proper venting, especially in shared-stack situations where the old coal flue may interfere with draft. We handle the full conversion, including gas line coordination, insert selection, liner installation, and final inspection. Everything documented, everything to code.

Trusted Brands We Service in Nazareth
We work exclusively with professional-grade materials from industry-trusted brands. For liners and relining, we use DuraFlex stainless steel and HeatShield resurfacing systems. For firebox repairs and refractory work, we specify HeatShield and Gelco products. For caps, dampers, and accessories, we stock Copperfield and Gelco lines. We don’t substitute builder-grade materials to hit a lower price. Our trucks carry common sizes and fittings, so most Nazareth repairs don’t wait on parts orders.
Common Fireplace Services Problems We See in Nazareth Homes
- Improvised-capped coal flues in shared stacks. On the older blocks near the historic borough center, we regularly find the former coal-furnace flue capped with sheet metal scraps, broken clay tile, or plywood from a 1950s conversion. When a later owner adds a wood stove or gas insert to the fireplace flue in the same stack, that blocked secondary flue creates a hidden backdraft and CO hazard that a cleaning alone won’t catch without a full camera inspection of both flues.
- Freeze-thaw spalling on exposed masonry crowns. The Lehigh Valley’s sharp late-winter temperature cycles fracture mortar crowns and open joints on Nazareth’s older chimneys. Spring rains then wash that loose material down into the flue and firebox, where it blocks airflow and accelerates deterioration. A post-winter inspection isn’t just recommended here; it’s genuinely functional maintenance.
- Clay-tile flues with cracked or missing tiles. The original clay liners in Nazareth’s 1880s-1920s chimneys have endured generations of acid flue gas and thermal shock. A cleaning brush can miss a missing tile entirely. Only a camera inspection reveals whether the flue needs HeatShield resurfacing, a stainless liner, or full relining. We don’t guess, and we don’t upsell liners on flues that only need crown and mortar work.
- Gas inserts vented into unlined or improperly lined coal-era flues. The flue that carried coal exhaust is oversized for modern gas appliances, producing poor draft and condensation that corrodes the chimney interior. We size liners to the insert manufacturer’s specification, not to the old flue dimension, and we verify with a draft test after installation.

FAQs - Fireplace Services in Nazareth
Yes. We camera-inspect every accessible flue in the stack, not just the one serving your fireplace. In Nazareth’s older borough-center homes, the second flue often served a coal furnace and was improperly capped during a mid-century conversion. We’ve found sheet metal, broken clay tile, and plywood blocking these flues. A blocked secondary flue can create backdraft and CO hazards when your fireplace or insert operates. Call (610) 595-5754 to schedule a full stack inspection.

Yes, especially in Nazareth. The Lehigh Valley’s freeze-thaw cycles damage mortar crowns and joints over the winter, and spring rains wash that debris into your flue and firebox. Even light use leaves some creosote, and the combination of loosened mortar and any accumulation creates a genuine blockage risk. We recommend a post-winter inspection and cleaning as functional maintenance, not just a calendar item. Estimates are free - call (610) 595-5754.

First-degree creosote brushes off easily, but its presence tells us the flue is running cool and the draft is sluggish. In Nazareth’s oversized coal-era flues, that’s often a symptom of a deeper problem: improper flue sizing, a blocked secondary flue disrupting airflow, or a deteriorating liner. We camera-inspect to find the cause. Brushing alone masks the symptom. Call (610) 595-5754 and we’ll show you what the camera sees.

Not necessarily. Original clay tiles can last centuries if intact. We camera-inspect to check for cracks, missing tiles, or gaps at the joints. If the tiles are sound but the mortar joints are deteriorated, HeatShield resurfacing may restore the flue at a fraction of liner cost. We only recommend full relining when the camera shows damage that resurfacing can’t address. You’ll see the photos and the verdict before any decision. Call (610) 595-5754 for a Level 2 inspection.

Yes, but the flue must be properly evaluated and usually lined. Coal flues are oversized for gas inserts, which produces poor draft and corrosive condensation. We size a DuraFlex liner to the insert manufacturer’s specification, verify proper connection at the collar, and test draft after installation. We also camera-check any secondary flues in the same stack for blockages that could create backdraft hazards. Call (610) 595-5754 to schedule an assessment.
