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.
Fast, Reliable Fireplace Services Across Andover
Fireplace service in Andover, MA typically runs $180-$650 depending on whether you need a routine gas fireplace tune-up, a wood-burning firebox rebuild, or a full insert installation in an older masonry chimney. Our crews are dispatched from our Boston office and cover Andover daily, including the historic Shawsheen Village brick rows and the colonial-era homes near Main Street. Call (351) 444-9705 and we’ll book a Level 2 camera inspection with a written price before any work starts.
We’ve worked Andover chimneys since 2009, and the calls we get here are different from Lawrence, Lowell, or Wilmington. The town’s mix of 18th-century center-corridor colonials, the uniform 1910s-1920s American Woolen Company brick blocks, and the sprawling post-WWII colonials on wooded lots means every fireplace service call requires reading the house before reading the flue. Our Fireplace Services team treats Andover as its own market, not a zip code on a route sheet.

Why Level Two Chimney Haverhill Is Andover’s Preferred Fireplace Services Company
We’ve completed more than 38,000 chimney inspections since 2009, and a disproportionate share of our liner assessments and historic firebox repairs come from Andover’s dense concentration of century-old masonry. The town’s housing stock simply produces more shared-stack, unlined-flue, and spalling-brick calls than neighboring communities.
Our technicians are background-checked, uniformed, and licensed - license number displayed on every page. You get a named tech, a text when they’re en route, and a documented photo record of every finding under Haven Standard Clause 4. That practice began with us in 2009, before insurers or regulators required it.
Every job carries the 365-Day Done Right Promise: if it’s not done right, we make it right. We also offer a Free Second Opinion on any competitor’s written estimate. Calls are answered live, 24 hours a day, not by voicemail or web form.
Our Boston office coordinates dispatch to Andover, so we’re not guessing drive times or local conditions. We know which Shawsheen Village streets share chimney stacks, which outer-colonial neighborhoods have multi-flue setups, and how Andover’s six-month heating season and freeze-thaw cycle from November through April punish mortar and crowns.
Our Fireplace Services in Andover

Gas Fireplace Service
Andover’s gas fireplace calls split two ways: modern direct-vent units in post-1980s colonials that need annual burner cleaning, safety-check, and vent inspection; and converted historic fireplaces in Shawsheen Village and downtown where a previous owner dropped in a gas log set without proper liner sizing. The second type is where we find cross-contamination risk - a neighbour’s furnace or water heater venting into the same shared stack, sending carbon monoxide through gaps in century-old masonry. Our gas service includes combustion analysis, pilot and thermopile testing, and a Level 2 camera scan of the full flue to verify no other appliance is sharing your airspace. Typical gas fireplace service in Andover runs $180-$280.

Wood Burning Fireplace
Andover’s long heating season and heavy snowfall mean wood-burning fireplaces here work harder than in milder climates. Active use from October through April produces significant Stage 2 and Stage 3 creosote accumulation, especially on unlined or deteriorating clay-tile flues common in pre-1950 homes. We sweep to NFPA 211 standards, then camera-scan to document liner condition. If we find spalling clay, exposed brick, or a missing liner, we quote a stainless DuraFlex liner or HeatShield resurfacing in writing before any repair begins. A wood-burning fireplace sweep and inspection in Andover is typically $240-$340; liner installation runs $1,800-$3,200 depending on flue height and access.

Fireplace Insert
Insert installations are our most common major fireplace project in Andover, and for good reason. The town’s thousands of original masonry fireplaces - beautiful, deep, and drafty - bleed heat up the chimney all winter. A properly sized EPA-certified insert, installed with a stainless liner from top to bottom, converts that liability into a 70%+ efficiency zone heater. We size inserts to your firebox dimensions and chimney height, pull proper permits, and run a new DuraFlex liner to the cap. In Shawsheen Village, we often pair insert installs with firebox refractory repairs because the original 1920s brick cannot handle modern combustion temperatures without cracking. Fireplace insert installation in Andover typically ranges $3,200-$5,800 including liner, pad, and surround.

Damper Repair
Andover’s freeze-thaw cycle destroys cast-iron throat dampers. We replace stuck, rusted, or misaligned dampers with precision-fit replacements - sometimes a new cast-iron frame and plate, sometimes a top-sealing damper/cap combination from Gelco or Olympia Chimney that stops rain and animal entry while sealing tighter than any throat damper. On shared Shawsheen Village stacks, we verify the damper repair doesn’t mask a deeper flue problem: a damper that won’t close fully can be a symptom of liner sag or masonry shift, not just rust. Damper repair or replacement in Andover runs $280-$520.

Firebox Repair
The firebox takes direct flame and thermal shock; in Andover’s oldest homes, original 19th-century brick and lime mortar have simply given out. We rebuild with refractory mortar rated to 2,500°F, replacing spalled brick and repointing joints to restore a true fire-safe enclosure. On Burnham Road and Morton Street, we’ve found fireboxes cracked so extensively that flames were licking the shared masonry wall between units - a genuine structure fire risk in attached rows. We document everything with photos, quote the rebuild in writing, and warranty the work under our 365-Day Done Right Promise. Firebox repair in Andover typically runs $850-$2,400 depending on depth of rebuild.

Fireplace Conversion
Converting a wood-burning fireplace to gas - or vice versa - in Andover requires navigating the town’s historic stock and its unique shared-stack configurations. We handle gas line coordination, proper liner sizing for the new appliance type, and permit documentation. In Shawsheen Village, conversions almost always require liner work because the original 1920s flue was never designed for modern gas venting temperatures and condensate patterns.

Common Fireplace Services Problems We See in Andover Homes

- Shared-stack cross-contamination in Shawsheen Village. The attached and semi-attached 1920s brick rows on Burnham Road, Morton Street, and surrounding blocks often have the same chimney stack passing through two or more dwellings. Your gas fireplace service call can reveal a neighbour’s furnace venting into your flue through gaps in spalling clay liner - a carbon monoxide hazard no surface inspection catches. Only a Level 2 camera scan finds it.
- Freeze-thaw mortar destruction on century-old exterior chimneys. Andover’s November-through-April freeze-thaw cycle, compounded by heavy snow load and ice damming, opens mortar joints and cracks chimney crowns. Water enters, freezes, expands, and repeats. By spring, the flue liner is wet, the smoke chamber is stained, and the firebox back wall is spalling. We see this pattern constantly in the oldest center-corridor homes.
- Unlined or deteriorating clay-tile flues in pre-1950 construction. Original clay liners in Andover’s historic housing stock were never designed for decades of wood-burning at modern intensities. The tiles crack, spall, and gap - sometimes so badly we can see into an adjacent flue or the chimney wall itself. A standard sweep cleans creosote but does not repair the liner; we quote DuraFlex stainless or HeatShield resurfacing based on what the camera shows.
- Multi-flue chimney neglect in post-WWII colonials. The larger colonials throughout Andover’s outer residential areas often have two or three fireplaces served by a single exterior stack. Homeowners use the family room fireplace regularly but forget the living room and bedroom flues - which may have deteriorated caps, animal nests, or water damage while sitting idle. Our inspection covers every flue in the structure, not just the active one.

FAQs - Fireplace Services in Andover

Yes, it fundamentally changes the scope of your service call. In Andover’s Shawsheen Village, the 1910s-1920s American Woolen Company brick rows were built with chimney stacks passing through or abutting multiple dwellings, so your flue may share masonry with - or directly connect to - a neighbour’s appliance vent. Our Level 2 camera inspection checks the full length of the flue and any visible adjacent passages; if we find cross-contamination, we document it with photos and explain your options, which may include installing a dedicated stainless liner to isolate your fireplace from the shared stack. Call (351) 444-9705 for a free estimate - we’ll scope the shared condition before quoting any work.

About one in three Andover sweeps we perform between March and May reveals freeze-thaw damage that requires repair before safe use the following season. The cycle opens mortar joints, cracks crowns, and saturates flue liners; by spring, what started as routine creosote removal becomes a crown rebuild, liner assessment, or firebox repointing. We camera-scan every sweep so you’re not surprised. If your chimney is pre-1950 and hasn’t had a Level 2 inspection in two years, assume there may be more than creosote waiting up there. Call (351) 444-9705 to book - estimates are free.

The American Woolen Company built those streets - Burnham Road, Morton Street, and the surrounding blocks - with identical brick, identical mortar, identical flue construction, and identical now-century-old clay liners. When we find spalling liner or cracked firebox in one unit, the neighbours have the same materials exposed to the same freeze-thaw cycles and the same heating-season workload. We’ve had single jobs on Burnham Road lead to five or six neighbouring homes with identical deterioration. We don’t canvass aggressively; technicians simply mention our findings to the customer, who tells neighbours, who call for their own inspections. The uniformity does the rest. Call (351) 444-9705 if you’re on one of these streets and haven’t had your flue camera-scanned.

Yes, for most Andover homeowners with a functional but inefficient open fireplace, an insert pays back through reduced oil or gas consumption over a typical six-month heating season. An EPA-certified insert converts 70%+ of wood energy into room heat versus 10-15% for an open fireplace, and the sealed combustion system eliminates the drafts that pull heated air up your chimney all winter. We size inserts to your firebox and run a new DuraFlex liner to the cap, which is required for safe operation and warranty compliance. In Andover’s climate, the break-even point typically falls between three and five heating seasons depending on your primary fuel costs. Call (351) 444-9705 for sizing and a written installed price.

Any firebox with cracked brick, missing mortar, or spalled refractory panels needs repair before firing - full stop. A compromised firebox allows flame, heat, and combustion gases to reach combustible framing or shared masonry walls, which is how chimney fires start and how carbon monoxide enters living spaces. Dampers that won’t open fully create smoke backup; dampers that won’t close bleed heat 24 hours a day. We inspect both components with camera and visual examination, quote repair in writing, and can often schedule firebox rebuilds or damper replacements within a week during off-peak months. Call (351) 444-9705 for a free inspection and written scope - no obligation, no pressure.
