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.

AfterTrusted Fireplace Services for Trenton Homeowners
Our Fireplace Services in Trenton typically cover inspection, repair, and conversion of gas and wood-burning systems, with most maintenance visits completed in under two hours and repair appointments available within a few business days. A properly serviced fireplace burns cleaner, drafts correctly, and won’t fill your Mill Hill or Berkeley Square living room with smoke or carbon monoxide.
We’ve been working on fireplaces in Trenton since 1984. That’s over 42 years of crawling into fireboxes in the historic homes near the State House, adjusting gas valves in the condos off Route 29, and rebuilding dampers in the post-war ranches around Hamilton Township. Russell Haines started this company on the idea that a craftsman should explain what he’s doing in plain English and stand behind it in writing. The 90-Day Done Right Promise still works that way: if it’s not right, we make it right, no paperwork and no arguing.
Our phones are answered by a live person, 24 hours a day, 7 days a week. Not a voicemail tree. Not a callback queue. A real person who can book your appointment or answer a question about that odd smell from your fireplace. Call (856) 519-0832 when you’re ready.

What Our Fireplace Services Include
Gas Fireplace Service
Gas fireplaces in Trenton sit idle from April through October, and that idle time causes problems. Spiders clog pilot orifices in the humid Delaware River valley summers. Thermopiles weaken and lose the millivoltage needed to open the gas valve. In the older homes off Perry Street and the newer builds near the Trenton Transit Center, we see the same pattern: the first cold night arrives, the pilot won’t stay lit, and the homeowner is left with a decorative black box instead of heat.
We service gas fireplaces by testing gas pressure at the manifold, inspecting the burner for corrosion or misalignment, checking the thermocouple and thermopile output with a digital multimeter, and verifying that the venting terminates correctly without obstruction. If your unit needs a new valve, pilot assembly, or ceramic log set, we carry common parts from DuraFlex and Famco on our trucks. Most gas fireplace services in Trenton are completed in a single visit.
Wood Burning Fireplace
A wood-burning fireplace in Trenton faces specific stresses. The freeze-thaw cycles of Mercer County winters crack mortar joints in the firebox. The heavy clay soils in neighborhoods like Chestnut Park and Wilbur shift foundations slightly, throwing off chimney alignment and creating gaps where smoke can leak into wall cavities. And the oak and maple that homeowners burn for heat produce acidic creosote that eats away at flue tiles over decades.
Our wood-burning fireplace service starts with a Level-2 camera inspection of the flue, documented with photos you can see. We check the firebox for missing or deteriorated brick, test the damper for proper opening and sealing, and examine the smoke chamber for parging damage. If we find cracked flue tiles or a deteriorated smoke chamber, we’ll explain exactly what it means, show you the photo evidence, and tell you whether it needs immediate repair or can be monitored. No scare tactics. No recommendations without proof.
Fireplace Insert
Fireplace inserts are essentially a wood stove or gas heater slipped into an existing masonry fireplace opening. They’re popular in Trenton’s older homes because they deliver real heat efficiency, turning a drafty open fireplace into something that can warm a room. But inserts are only as good as their installation. An improperly sized liner, a blocked outside air intake, or a gap between the insert surround and the fireplace face can cause smoke spillage, carbon monoxide risk, or house fires.
We install and service fireplace inserts from major manufacturers, connecting them to properly sized stainless steel liners from DuraFlex and ensuring the surround meets clearance requirements. For existing inserts, we remove the unit when possible to inspect the liner condition, clean the combustion chamber and glass, and replace worn gaskets and door seals. An insert service in Trenton typically takes 90 minutes to two hours, depending on access.
Damper Repair
The damper is the metal plate that seals your fireplace flue when it’s not in use. A damper that won’t open fully means smoke in your living room. A damper that won’t close means heated air escaping up your chimney all winter, and in summer, humid outside air pouring down to rust your firebox. In Trenton’s hundred-year-old homes, we’ve seen cast-iron throat dampers rusted solid, warped by chimney fires, or jammed with fallen mortar from deteriorated crowns above.
We repair and replace throat dampers and install top-sealing dampers from Copperfield when the throat damper is beyond saving. A top-sealing damper mounts at the chimney top and seals with a silicone gasket, eliminating the heat loss and animal entry that throat dampers can’t prevent. We can test your existing damper’s seal with a smoke pencil and show you exactly where the air leaks. Most damper repairs in Trenton are completed in one visit, with the technician explaining your options before any work begins.
Firebox Repair
The firebox is where the fire actually lives, brick or refractory panels that take direct flame and 1,200-degree temperatures. In Trenton, we see firebox damage from three main causes: years of over-firing (burning too hot), water infiltration from a failed chimney crown, and simple age-related deterioration of the original refractory mortar. Cracked firebrick or spalling panels aren’t just cosmetic. They allow heat to reach combustible framing behind the fireplace, and in a severe case, they can lead to a structure fire.
We repair fireboxes by replacing damaged brick with matching firebrick set in refractory mortar, or by installing prefabricated refractory panel systems from HeatShield when the damage is extensive. For minor cracking, we apply HeatShield’s cerfractory resurfacing compound, which is rated to 2,200 degrees and carries a 20-year warranty. Every firebox repair includes a camera inspection of the surrounding flue to ensure there’s no hidden damage above. We don’t close up a firebox without knowing the whole chimney is sound.
Fireplace Conversion
Converting a wood-burning fireplace to gas, or switching from an old standing-pilot gas system to modern direct-vent or vent-free, is a significant job that affects your home’s safety for decades. In Trenton, conversions are common in homes where the original owners have aged out of hauling firewood, or where the masonry chimney is deteriorated and a direct-vent gas insert avoids expensive rebuild costs. But conversions require proper gas line sizing, combustion air calculations, and venting that meets both manufacturer specs and local code.
We handle fireplace conversions from start to finish: gas line extension or replacement, proper venting with DuraFlex or manufacturer-approved materials, and final inspection to ensure compliance with Trenton’s building department requirements. We’ll also tell you honestly when a conversion isn’t the right choice, if your chimney condition or home layout makes it unsafe or impractical. A conversion consultation in Trenton includes a full inspection, a written estimate with no obligation, and photos of anything we find that affects the project scope.
Brands We Service for Fireplace Services
We’ve worked on thousands of fireplace units across Mercer County, and we maintain active familiarity with the brands that hold up in real-world conditions. For gas fireplaces and inserts, we regularly service and install units from manufacturers whose venting and component systems we know inside out. We’ve installed DuraFlex stainless steel liners and venting in hundreds of Trenton homes, from the bungalows near Cadwalader Park to the center-hall colonials in Hiltonia. We stock common DuraFlex components and can fabricate custom transitions when an existing flue doesn’t match standard dimensions.
HeatShield’s cerfractory resurfacing systems are our go-to for firebox and smoke chamber restoration. We’ve applied their products in dozens of Mercer County fireplaces, and we appreciate that their warranty is transferable and their application process is documented with before-and-after photos. For chimney caps, dampers, and exterior components, we install Copperfield and Famco products exclusively. Copperfield’s stainless steel caps with integrated animal guards hold up to Trenton’s wet winters without the rust-through we see on big-box store versions. Famco’s top-sealing dampers provide a positive seal that throat dampers simply can’t match.
Whether your fireplace is a HeatShield-restored firebox, a DuraFlex-vented gas insert, or a unit from any other manufacturer, we can service it correctly. We don’t guess at compatibility or substitute generic parts. If we don’t stock it, we order the right component and schedule the follow-up.
Signs You Need Fireplace Services Right Now
- Smoke spills into the room when you light a fire. This means your chimney isn’t drafting properly, and the cause could be a blocked flue, a stuck damper, or negative air pressure from your home’s HVAC system. In Trenton’s tighter modern homes, we see this increasingly from house depressurization, not chimney blockage. Either way, breathing wood smoke is harmful, and the problem won’t fix itself.
- You smell gas near the fireplace when it’s off. Natural gas and propane are odorized specifically so you’ll notice a leak. A gas smell indicates a failed valve, loose fitting, or cracked pilot tubing. Don’t light the fireplace. Don’t assume it’s normal. Call us or your gas utility immediately. This is not a wait-and-see situation.
- The firebox has visible cracks, missing mortar, or spalling brick. Heat escaping through damaged firebox walls reaches the wood framing behind your fireplace. In Trentin’s older homes with balloon framing, that heat can travel quickly. We document firebox damage with photos and explain whether resurfacing, panel replacement, or rebuild is appropriate.
- Your gas fireplace pilot won’t stay lit or the burner flames are uneven. A pilot that drops out after releasing the button usually means a weak thermocouple. Uneven burner flames suggest clogged ports or improper gas pressure. Both are fixable in a single visit, but both also indicate the unit is overdue for professional service.
- Water stains appear on the ceiling or walls near the chimney breast. Water and chimneys destroy each other. Stains mean your chimney crown, flashing, or cap has failed, and water is running down inside the masonry. In winter, that water freezes and expands, accelerating damage. The fireplace below is affected too, as water rusts dampers, deteriorates fireboxes, and ruins gas valves.
Our Fireplace Services Process - Step by Step
- 1
Call and speak with a live person. When you call (856) 519-0832, a real person answers, 24 hours a day, 7 days a week. We’ll ask about your fireplace type, the symptoms you’re seeing, and your schedule. We’ll give you a realistic arrival window, not a four-hour guess. We’ll also confirm our $89 Seasonal Tune-Up if you’re due for routine maintenance, or note any applicable discount.
- 2
Arrival and protection of your home. Our technician arrives in a marked vehicle, in uniform, with a background check on file. We lay drop cloths from the door to the fireplace and use HEPA vacuums if soot or debris will be disturbed. We treat your Mill Hill Victorian or your Robbinsville townhouse with the same care we’d want in our own homes.
- 3
Inspection with documentation. Every fireplace service includes visual and camera inspection appropriate to the system. For wood-burning fireplaces, we run a chimney camera to document flue condition. For gas units, we test with a digital manometer and combustion analyzer. You receive photos of anything we find, with a plain-English explanation of what it means and whether it needs immediate action.
- 4
Upfront pricing and your approval. Before any repair work begins, you get a written estimate with the exact price. The number on the estimate is the number on the invoice. No surprises, no “while we were in there” additions. If we discover something unexpected, we stop and explain it with photo evidence before proceeding. You’re in control of every dollar spent.
- 5
The work, the cleanup, and the written guarantee. We complete most fireplace services in a single visit, using professional-grade materials from our stocked inventory. When we’re done, we clean thoroughly, test the system for proper operation, and leave you with a written summary and the 90-Day Done Right Promise. If anything isn’t right, we come back and make it right. In writing. No arguing.
How Much Does Fireplace Service Cost in Trenton?
How much Fireplace Services costs in Trenton depends on what your system needs and what we find during inspection. Here are the typical ranges we see in Mercer County:
| Service | Typical Range | What Affects Price |
|---|---|---|
| Gas fireplace tune-up and safety check | $89-$175 | Accessibility, parts needed (thermocouple, pilot assembly), venting configuration |
| Wood-burning fireplace inspection and sweep | $175-$295 | Flue length, creosote buildup level, need for camera inspection |
| Damper repair or replacement | $225-$650 | Throat vs. top-sealing damper, chimney access difficulty |
| Firebox repair (minor resurfacing) | $450-$950 | Surface area, material (HeatShield vs. refractory panels) |
| Fireplace insert installation | $2,800-$5,500 | Insert model, liner length and diameter, gas line extension needed |
| Fireplace conversion (wood to gas) | $3,200-$7,500 | Gas source distance, venting requirements, finishing carpentry |
Several factors push prices higher or lower. A gas fireplace with a simple thermocouple replacement runs at the low end. A wood-to-gas conversion in a historic Trenton home with no existing gas line and a deteriorated chimney requiring full liner replacement runs higher. The condition of your chimney crown and flashing affects whether we can focus on the fireplace itself or need to address water intrusion first.
To avoid overpaying, get a second opinion on any estimate over $500. We offer a Free Second Opinion on any written estimate from another company. Bring us their paperwork and we’ll inspect independently, with no obligation. We also offer $50 off any repair over $250, and a permanent 5% discount for seniors and veterans.
Every estimate we provide is free and includes the camera inspection and photo documentation. You’ll see what we see before you spend a dollar. Call (856) 519-0832 for your exact quote.
