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.

Why Emberly Chimney Cleaners Is Nashua’s Preferred Fireplace Services Company
Nashua’s housing stock is unusual, and it rewards a sweep who understands the difference between a 1920s triple-decker flue on French Hill and a 1992 zero-clearance firebox in a colonial off exit 4. Our Fireplace Services team has worked both, and we’ve been documenting every job with a camera scan since 2009, years before insurers started asking for it. That archive now spans more than 38,000 chimneys inspected and cleaned, most in markets like Nashua where factory-built fireplaces dominate the post-1975 build-out.
Nashua homeowners tend to research before calling. They read the three-star reviews and they want the price on the page, not hidden behind a form. That’s why every job we quote includes a written scope, a written price, and a written warranty before anyone touches your fireplace. Corrine Halstead, our owner, built the company on that habit: say what we found, name what it costs, and show you the photos when we’re done. Clause 4 of the Haven Standard requires it.
We answer the phone 24/7 with a live person, and when you book, you’ll get a text when the technician is on the way. For Nashua, that usually means one to two business days for non-emergency service, and same-week availability during the fall preseason when most homeowners are scheduling before the first cold snap.
Our Fireplace Services Services in Nashua

We handle the full range of fireplace work across Nashua, and on this page we’re going to focus on the four services Nashua homeowners call us about most. Each one gets a written price before work starts.
Gas Fireplace Service
Nashua’s oil-to-gas conversion wave in the 2000s left a lot of homes with gas fireplace inserts venting through flues that were sized for something else entirely. That mismatch causes condensation, which eats at clay tile and rusts dampers from the inside. A standard gas fireplace service in Nashua runs $160-$290 and includes cleaning the burner, checking the thermocouple and pilot assembly, verifying venting clearances, and a camera scan of the flue. If you smell gas or the fireplace won’t stay lit, call us before you run another cycle; the problem is usually the thermopile, but venting issues can’t be diagnosed by ear.

Wood Burning Fireplace
Nashua sits in the Merrimack River valley, and our heating season runs October through April. That’s seven months of regular burns, and in a cold year we see creosote accumulate two to three times faster than in milder climates just south of the Massachusetts line. A wood burning fireplace cleaning in Nashua costs $150-$250 and includes a full sweep of the firebox, smoke chamber, and flue, plus a creosote classification you can see in the photo report. We’ll tell you if you’re dealing with Class II or Class III creosote and what that actually means for your burn habits.

Fireplace Insert
Nashua’s post-1975 suburbs were built with factory-made zero-clearance fireplaces, not full masonry systems. Those units have a 20 to 25 year design lifespan, and the ones installed between 1982 and 1998 are now past it. When the refractory panels crack or the flex liner pits through, the fix is usually a new UL-listed insert with a properly sized liner. A full fireplace insert replacement in Nashua runs $1,800-$4,600 depending on the unit’s face dimensions, venting configuration, and whether the existing chase can be reused. We carry materials from DuraFlex, Famco, and Copperfield so we’re not waiting on a distributor for common sizes.

Damper Repair
A damper that won’t open or close is usually one of three things in Nashua: rust from condensation in a converted oil-to-gas flue, a warped frame from heat cycling in a zero-clearance box, or simple linkage wear in a unit that’s been in service since the Clinton administration. Damper repair runs $220-$480 in Nashua, and we’ll tell you plainly when a replacement is the better use of your money. In some factory-built fireplaces from the early ’90s, the damper assembly is no longer manufactured, and we’ll say so rather than charge you for a patch that fails next season.

Before
AfterTrusted Brands We Service in Nashua
We work on factory-built units from the brands that dominated Nashua’s 1980s and 1990s housing boom, plus the inserts and liners homeowners have added since. We stock common parts for Famco dampers, Copperfield surrounds, and DuraFlex liner systems, which means a damper repair or liner replacement in Nashua usually doesn’t wait on a backorder. If we’re replacing a liner, we quote the specific brand and thickness in writing, and the photo report shows the old liner next to the new one so there’s no guesswork about what you paid for.
Common Fireplace Services Problems We See in Nashua Homes

- Cracked refractory panels in 1980s-1990s zero-clearance units. These panels sit at the back of the firebox and absorb heat shock every burn. In Nashua’s factory-built stock, we see hairline cracks that let flame reach the metal firebox shell, which is not rated for direct flame exposure. Once that happens, the unit needs to come out, not be patched.
- Shared flues venting a neighbor’s gas appliance into your fireplace. Pre-war triple-deckers on French Hill and the downtown blocks often have two or three units tied into one masonry stack. When one owner converts from oil to gas without relining, combustion gases can push into an adjacent unit’s fireplace. We camera-scan the full run to map exactly where your flue starts and ends.
- Condensation and spalling in converted oil flues off Daniel Webster Highway. The ranch homes built in the 1960s and 1970s used oversized clay-tile flues sized for high-BTU oil boilers. A modern 80% efficiency gas appliance vents at a lower temperature, which means the flue never warms up enough to dry out. The result is acidic condensation that spalls the tile from the inside, and we see it constantly in that corridor.
- Freeze-thaw crown damage near the Merrimack River. Ground moisture plus the river’s proximity means chimney crowns here take more freeze-thaw cycles than homes up on the ridge. A cracked crown lets water into the firebox, which rusts dampers and stains the ceiling below. We seal crowns with a breathable repellent and document the before and after on camera.

FAQs - Fireplace Services in Nashua

Expect us to find something. Zero-clearance units installed in Nashua between roughly 1982 and 1998 are past their 20 to 25 year design lifespan, and an untouched unit from that era almost always shows cracked refractory panels, a deteriorated flex liner, or both. We’ll camera-scan the entire flue run, show you the footage on site, and tell you in plain terms whether the unit can keep running safely or needs to be replaced. If it can wait, we’ll say so. Call (980) 580-8641 to book the inspection.

The flue was sized for an oil boiler, not an 80% efficiency gas appliance. Oil burners run hot and push a lot of exhaust volume, so the clay tiles were sized to handle that. Gas appliances run cooler and push less volume, which means the flue stays below the dew point longer and condensation forms inside. That condensation is acidic, and it spalls the clay tile from the inside out. The fix is usually a properly sized stainless liner. We’ll show you the camera footage of the spalling before we quote you a liner, and the price is on paper before we start.

You camera-scan the full flue run and document exactly which openings are tied to your fireplace. In pre-war triple-deckers on French Hill, shared masonry stacks often have multiple appliance openings, and when one unit converts from oil to gas without relining, combustion gases can push into a neighboring unit’s fireplace. A properly installed liner that terminates cleanly at your fireplace opening solves it. We’ll map the flue, write down what we found, and give you a quote that includes relining your run only. Call (980) 580-8641 and we’ll set a time to scan it.

Once a year if you burn more than a cord of wood, and ideally in the early fall before the burn season starts. Nashua’s heating season runs October through April, and with 60 to 65 inches of annual snowfall, locals burn hard. That means creosote accumulates faster here than in milder parts of Massachusetts, and an annual sweep plus inspection keeps a Class II buildup from becoming Class III, which is the glaze-like stage that’s hardest to remove and most prone to chimney fire. A standard cleaning and inspection is $150-$250, and it includes the photo record we file on every job.

Repair means we can restore the existing damper assembly to function, usually by replacing the linkage, freeing a rusted pivot, or straightening a warped frame. Replacement means the existing assembly is too far gone, or the manufacturer no longer makes parts for that unit, and the entire damper assembly comes out and a new compatible one goes in. On 1990s zero-clearance units in Nashua, replacement is common because several manufacturers from that era discontinued their parts lines years ago. We’ll show you the failed part, quote repair and replacement as separate line items, and let you choose with the numbers in front of you.
Last fall, our crew serviced a colonial off Amherst Street where the original zero-clearance firebox in the family room had a hairline crack running through the back refractory panel. The homeowner had been burning seasoned hardwood every weekend since moving in during the early ’90s, and the factory flex liner was now pitted and weeping at the seams. We pulled the old firebox, installed a new UL-listed insert with a properly sized DuraFlex liner, and replaced the warped damper. The draft improved so much that the homeowner said they could finally sit on the couch without smelling smoke.
If you’re in Nashua and your fireplace hasn’t been looked at in years, call (980) 580-8641 for a free estimate. We’ll show you exactly what’s in your flue before you spend a dollar fixing it, and you’ll walk away with a written price, a written scope, and a written warranty on every job we do.
