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 on Mercerville chimneys for decades. The Cape Cods and ranch homes off Edinburg Road, the split-levels near the Hamilton Marketplace corridor, the brick colonials along Route 33 - we’ve swept and inspected them all. These aren’t theoretical houses to us. They’re the same postwar stock built for Trenton-area workers between 1950 and 1975, with the same original clay-tile flues, the same low-pitch rooflines, and the same problems that develop when a 60-year-old chimney meets a modern, tightened-up house.
Why Hearthstone Chimney Co. Is Mercerville’s Preferred Chimney Cleaning & Sweep Company
Our reputation in Mercerville was built one appointment at a time. Homeowners here talk to their neighbors. They remember which contractor showed up on time, which one tracked mud through the living room, and which one tried to sell a $4,000 liner on a chimney that only needed a sweep and a crown seal. We don’t do that. Our 90-Day Done Right Promise - in writing, no arguing - means if something isn’t right, we come back and make it right.
Dispatch and scheduling are coordinated from our New York City office, but our crews serve Mercerville locally and know the area’s housing stock cold. We’ve worked on the short chimney stacks in the Nottingham Way area, the ranches near Mercerville’s border with Hamilton Square, and the older Capes closer to White Horse. That local knowledge matters when you’re diagnosing why a chimney backdrafts or where water is getting in.
A live person answers every call, every hour, every day. Not a voicemail tree. Not a callback queue. When you call (856) 388-5580, you get someone who can book your appointment, answer your questions, and send the right technician with the right equipment.
Our Chimney Cleaning & Sweep Services in Mercerville
Level 1 Inspection
A Level 1 inspection is the baseline for any Mercerville chimney that’s been in regular use without changes to the appliance or venting system. We examine the readily accessible portions of the chimney exterior, interior, and connections - looking for creosote buildup, obstructions, and basic structural soundness. For many Mercerville ranch and Cape Cod owners, this is the annual checkup that keeps the homeowner’s insurance satisfied and the fireplace safe to use. We document what we find and give you a plain-English verdict. No jargon, no scare tactics.

Level 2 Inspection
This is where we do our best work in Mercerville. A Level 2 inspection includes everything in Level 1 plus a camera scan of the full flue interior - and on Mercerville’s 50-70-year-old clay-tile chimneys, that camera changes everything. We run it top to bottom, record the footage, and show you what we’re seeing on screen. Cracked tile. Spalling flue sections. Mortar joints turned to powder. Third-degree creosote glazing the smoke chamber black. You see it with your own eyes. We explain what it means, what your options are, and what can safely wait. Nothing is recommended without camera evidence you can see for yourself.
On a Cape Cod off Edinburg Road in Mercerville, our tech pulled a 1962 firebox apart and found the original clay tile flue liner cracked and spalling, with heavy third-degree creosote glazing the smoke chamber from backdrafting after the homeowner’s blown-in attic insulation. We ran a camera down the flue, showed the homeowner the cracked tile on screen, then installed a HeatShield liner and Gelco crown - no upsell, just the footage.

Creosote Removal
Creosote in Mercerville isn’t just a byproduct of burning wood. It’s a symptom of how these older houses have been modified over decades. When homeowners add blown-in attic insulation and replacement windows - extremely common in Mercerville’s postwar stock - the tightened building envelope starves the firebox of combustion air. The result is incomplete combustion, cooler flue temperatures, and third-stage creosote: a hard, glazed, tar-like coating that standard wire brushes won’t touch. We use professional-grade rotary cleaning systems and chemical treatments to break down glazed creosote safely. This is not a DIY job. Third-degree creosote is highly combustible and requires proper equipment and technique to remove without damaging the flue.

Soot Removal
Standard soot buildup responds well to a proper sweep with the right diameter brush and rods. In Mercerville, we see heavy soot accumulation in chimneys venting older oil or gas appliances into flues that were never properly sized for them. The soot itself isn’t the fire hazard that creosote is, but it restricts draft, reduces efficiency, and can release carbon monoxide into the living space if the flue is compromised. We remove it completely and check the flue for cracks or blockages while we’re at it.

Annual Sweep
For Mercerville homeowners who use their fireplace regularly, an annual sweep is the single best investment in safety and performance. The National Fire Protection Association recommends it. Your homeowner’s insurance likely requires it. And given Mercerville’s hard freeze-thaw cycles and aging chimney stock, skipping a year means gambling on hidden damage you won’t discover until it’s expensive or dangerous. We book annual sweeps in advance so you don’t have to remember - we’ll call you when it’s time.

Common Chimney Cleaning & Sweep Problems We See in Mercerville Homes
- Cracked clay-tile flue liners from freeze-thaw cycling. Mercerville’s 20-25 inches of annual snowfall and hard freeze-thaw cycles drive moisture into aging brick chimneys. The original 1950s-1970s clay tile flues crack and spall, creating gaps that can leak carbon monoxide into living spaces. A brush-only sweep without a camera inspection misses this entirely.
- Chronic backdrafting from tightened building envelopes. Decades of attic insulation and replacement windows in Mercerville’s ranches and Capes starve fireboxes of combustion air. The result is smoke rolling back into the room, poor draft, and third-degree creosote buildup even on rarely used fireplaces.
- Flashing and crown failure on short, low-pitch chimney stacks. Mercerville’s ranch homes often have chimneys that barely clear the ridge line. When the crown cracks or flashing pulls loose, spring moisture drives directly into the brickwork. By the time water stains appear inside, the damage is extensive.
- Appliances vented into flues never designed for them. Original Mercerville chimneys were built for open fireplaces, not modern high-efficiency furnaces or water heaters. The cooler exhaust condenses, accelerates corrosion, and produces acidic condensation that eats clay tile from the inside out.

FAQs - Chimney Cleaning & Sweep in Mercerville
Yes. On Mercerville’s original clay-tile flues, a brush-only sweep can miss cracked or spalling tile that creates a carbon monoxide hazard. We run a camera before we recommend any work beyond the sweep itself. You see the footage. We explain what it means. Some cracks can be monitored. Others need immediate attention. But you won’t get a sales pitch for a liner you don’t need - the camera evidence speaks for itself. Call (856) 388-5580 to schedule a Level 2 inspection with your sweep.
Backdrafting in Mercerville Capes is almost always caused by a negative pressure house - too much air being exhausted by kitchen fans, dryers, and bathroom vents, with too little makeup air because of replacement windows and attic insulation. The chimney can’t draft against that pressure imbalance. We diagnose it during our inspection, check for proper combustion air supply, and clear any creosote buildup that’s restricting the flue. Sometimes the fix is mechanical - a combustion air duct or a properly sized liner. Sometimes it’s operational - how you run the house. We’ll tell you straight which it is.
The NFPA says annually for any chimney in use. In Mercerville, with our hard freeze-thaw cycles and the age of the housing stock, we agree - and we’d push harder for homeowners with original clay-tile flues. An annual sweep catches creosote before it becomes a fire hazard and gives us a chance to camera-inspect for tile degradation that accelerates in winter. Skip two years and you’re gambling on hidden damage that a camera would have caught early. We offer annual plan scheduling so you don’t have to keep track.
Third-degree creosote is a hard, glossy, black or dark-brown glaze that looks like tar baked onto the flue walls. A standard wire brush won’t touch it. We see it constantly in Mercerville on chimneys with backdrafting problems - the cooler flue temperatures from poor draft cause incomplete combustion and heavy glazing. Removal requires rotary cleaning heads and professional-grade chemical treatments to soften the deposit before mechanical removal. It’s specialized work, and it’s not safe to attempt without proper equipment. We include third-degree creosote assessment in every Level 2 inspection.
It’s related, and we’ll flag it during any sweep or inspection. A crumbling crown and loose flashing are water entry points that destroy chimneys from the top down - especially on Mercerville’s short-stack ranches where the crown takes direct weather exposure. We can reseal or rebuild crowns with professional-grade materials and repair flashing as part of a service call. If the damage is extensive, we’ll show you the photos, explain the options, and schedule the repair. But we won’t let you walk away from a sweep without knowing the crown condition. Water damage doesn’t fix itself.
