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.

Calls are answered by a live person, every hour of every day. Our background-checked, uniformed technicians arrive with no-hassle upfront pricing - the number on the estimate is the number on the invoice. Most jobs are completed in a single visit.
We know the shallow-pitched ranch rooflines that collect ice along MacArthur Road, the original brick chimneys in the Fullerton Heights neighborhood with no clay tile liner, and the freeze-thaw punishment that Lehigh Valley winters deliver between South Mountain and Blue Mountain. That local knowledge changes what we look for - and what we find.
Our Fireplace Services in Fullerton
Gas Fireplace Service
Gas fireplaces in Fullerton often run into a problem the homeowner can’t see: the chimney they vent into was never designed for them. Many Fullerton homes converted from coal or oil heating to gas inserts without properly resizing the flue. We inspect the burner assembly, check gas pressure and venting, and run a camera to confirm the flue matches the appliance. If you’re in a ranch off Schoenersville Road or a cape cod near the Fullerton Fire Company, we’ve likely serviced a home with your exact chimney profile.

Wood Burning Fireplace
Wood burning in a Fullerton chimney demands a flue sized correctly for the appliance and free of deteriorated clay tile. The acidic condensate from decades of oil-fired heating eats clay liners from the inside out, leaving gaps and spalling that wood-stove exhaust will exploit. We sweep, camera-inspect, and give you a plain verdict on whether your flue is sound - or whether it needs relining with professional-grade materials before you light another fire.

Fireplace Insert
This is where Fullerton’s housing stock creates the most invisible danger. A gas or wood insert dropped into a wide, rectangular coal-era flue with an undersized flexible liner stuffed down the middle leaves a gap that collects creosote and traps moisture. From the firebox, it looks fine. Our camera shows the truth. We size the liner correctly to the appliance, using HeatShield or DuraFlex where appropriate, and we document the before and after so you understand exactly what was wrong and what we fixed.

Damper Repair
Fullerton’s freeze-thaw cycles warp and corrode dampers faster than in more temperate zones. A stuck or rusted damper wastes heat, invites drafts down your flue, and can prevent proper draft when you do want a fire. We repair or replace throat and top-sealing dampers, including Gelco and Olympia Chimney hardware sized to your flue. If the damper is seized in a home that’s sat vacant through a Lehigh Valley winter, we’ll get it moving or get it replaced - and show you the photo of why it failed.

Firebox Repair
The firebox takes the direct heat, and in Fullerton’s older homes, the refractory panels or brick lining may have decades of thermal cycling behind them. Cracked fireboxes let heat reach combustible framing - a real hazard, not a sales pitch. We assess with a camera and light, quote the repair upfront, and use professional-grade refractory materials. No recommendation without evidence you can see for yourself.

Fireplace Conversion
Converting a wood fireplace to gas - or updating an old gas setup - in Fullerton means confronting the flue-sizing question honestly. We do not install an appliance into a chimney we haven’t camera-inspected. The conversion is quoted completely, with the flue work included if needed, and documented with photos. Done right - and we stand behind it.

Trusted Brands We Service in Fullerton
We stock and install professional-grade materials from HeatShield, Gelco, Olympia Chimney, and Famco - brands we trust because they’ve held up in Lehigh Valley conditions. Our Philadelphia warehouse keeps common parts and liner sizes on hand, so Fullerton customers aren’t waiting on backorders while burning season slips away. We don’t substitute builder-grade materials to hit a price point. The brands we use are the brands we specify, and the warranty runs through us with the 90-Day Done Right Promise behind it.
Common Fireplace Services Problems We See in Fullerton Homes
- Retrofitted gas inserts with flexible liners stuffed into oversized, unlined coal or oil flues. The gap between liner and flue wall collects third-degree creosote and traps moisture. It’s invisible from the firebox and undetectable without a camera scan - a failure mode our technicians find repeatedly in Fullerton’s post-WWII housing.
- Spalled mortar joints and loose chimney crowns from Lehigh Valley freeze-thaw cycles. The bowl between South Mountain and Blue Mountain channels cold air and drives hard winter temperature swings. Water gets in, freezes, expands, and pops the face off brick and mortar. Shallow-pitched ranch rooflines make it worse.
- Ice damming on those same ranch rooflines rotting flashing at the chimney base. Fullerton’s compact ranches shed snow slowly. Ice backs up under shingles and finds the chimney flashing. By spring, the wood’s soft and the leak’s inside the wall.
- Appliances vented into stacks never designed for them. Original clay tile liners, deteriorated by decades of acidic oil-flue condensate, are now asked to handle a wood stove or gas insert they can’t safely contain. The sizing is wrong. The liner is compromised. The homeowner doesn’t know until we show them.

FAQs - Fireplace Services in Fullerton
Your chimney was built for a coal stoker or fuel-oil furnace, not a fireplace or insert. Fullerton’s post-WWII housing stock was constructed with wide, rectangular flues sized for those heating systems, and most were never lined with clay tile. When a later owner added a fireplace or gas insert, the flue was left oversized and often unlined - a mismatch that affects draft, safety, and efficiency. We camera-inspect to document exactly what you have and what it needs. Call (610) 632-1394 for a free evaluation.

A camera scan shows the interior flue surface in its entirety - gaps between a liner and flue wall, deteriorated clay tile, creosote buildup in corners a brush misses, and moisture staining that indicates leaks. From the firebox, a chimney can look sound while the camera reveals a liner gap collecting creosote or a spalled section ready to let flue gases escape. We provide the photos and a plain-English verdict. Nothing is recommended without evidence you can see.

No. A full reline is necessary only when the existing flue is unsound, improperly sized, or unlined and cannot be made safe for the appliance venting into it. Sometimes a partial repair, HeatShield application, or damper correction solves the problem at a fraction of the cost. We determine this with a camera inspection, not a guess from the driveway. If another company recommended a reline, our free second opinion includes the photos to show you whether it’s truly needed.

The Lehigh Valley’s hard freeze-thaw cycles - driven by cold air channeling between South Mountain and Blue Mountain - attack mortar and concrete aggressively. Fullerton’s shallow-pitched ranch roofs compound this by trapping snow and ice against the chimney base, where repeated thawing and refreezing flexes the flashing until it separates. Crown cracks let water into the chimney structure; flashing gaps let it into your home. We repair with materials formulated for this climate, not generic mixes that won’t survive the winter.

Yes, and this is exactly the situation we handle most often in Fullerton. The key is verifying that the liner is sized correctly to the insert and that no gap exists between liner and flue wall. On a ranch off MacArthur Road, our tech scoped a chimney that had been retrofit with a gas insert using an undersized DuraFlex liner crammed down the center of a wide oil-era flue. The camera showed a ring of third-degree creosote and trapped moisture in the gap between liner and brick - invisible from the firebox. We pulled the liner, ran HeatShield to re-line the flue to the correct size, and corrected the draft. We can assess your setup and give you a straight answer on whether it’s safe as-is or needs correction. Call (610) 632-1394 to schedule.
