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 worked on Andover chimneys since 2009, from the colonial-era and Victorian homes along the town center corridor to the post-WWII colonials on wooded lots throughout the outer residential areas. Our technicians know the local building stock: multi-flue stacks serving two or three fireplaces in larger colonials, original fieldstone or brick foundations in the oldest homes, and the unique concentration of century-old masonry in Shawsheen Village that makes Andover’s chimney repair needs genuinely different from neighboring Merrimack Valley towns.

Our Chimney Repair Services in Andover
Mortar Repointing
Mortar repointing in Andover runs $1,200-$2,800 for a typical single-flue stack, with multi-flue chimneys on larger colonials trending toward the higher end. The freeze-thaw cycles here run November through April, and that relentless expansion and contraction grinds away mortar joints on older masonry. In Shawsheen Village, we regularly find 1910s-1920s brick where the original lime mortar has turned to powder, letting water penetrate straight to the flue. We grind out the failed joint to proper depth, match the mortar composition to the original brick, and repoint by hand. Every repointing job includes a Level 2 camera inspection of the flue interior and a written warranty under the Haven Standard.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is what we see when moisture trapped behind deteriorating mortar freezes and pushes the brick surface off. In Andover, this shows up aggressively on chimneys with failed crowns or deteriorated pointing, especially after wet winters. Spalling brick repair typically costs $1,500-$3,500 depending on how many courses need replacement and whether the damage extends to the chimney crown. We source matching brick through our Haven buying network and replace damaged courses, then address the water entry point that caused it. Without fixing the source, new brick will spall again in two or three seasons.
Chimney Waterproofing
Andover’s six-plus months of heating season and heavy snowfall mean chimneys stay wet and cold for extended periods. Waterproofing a masonry chimney in this market runs $800-$1,400, including thorough cleaning, repair of minor mortar cracks, and application of a vapor-permeable silane/siloxane sealant that lets the brick breathe while shedding water. We use products procured through our Haven buying network, applied only after the masonry is confirmed dry and the crown is sound. Waterproofing a chimney with active leaks or failed pointing first is a waste of your money, and we’ll tell you so before quoting.
Flashing Repair
Chimney flashing repair in Andover costs $650-$1,500, with full replacement of step flashing and counterflashing on steep-pitch roofs at the upper end. The intersection where your chimney meets the roof is the most common leak point we find during Level 2 inspections, and in Andover’s older center-corridor homes the original flashing is often galvanized steel that’s corroded through or was never properly integrated with the roofing membrane. We fabricate custom flashing to match your roof pitch and chimney profile, seal with high-temperature sealant, and document the completed work with photos for your record.
Chimney Rebuilding
When spalling, mortar failure, or structural shifting has compromised the stack beyond repair, partial or full chimney rebuilding becomes necessary. In Andover, this typically ranges from $3,500 for a partial rebuild of the upper courses to $8,500 or more for a full teardown and reconstruction of a multi-flue stack on a large colonial. We rebuild to current code with proper flue liner sizing, adequate clearance to combustibles, and a poured concrete crown with proper drip edge and slope. Every rebuild includes the full Level 2 inspection, photo documentation, and written warranty under Haven Standard Clause 1: Have it in writing.

AfterTrusted Brands We Service in Andover
We source repair materials through the Haven buying network specifically to keep customer prices honest: HeatShield cerfractory flue liner resurfacing systems for deteriorated clay tiles, Gelco stainless steel chimney caps and chase covers, and Olympia Chimney liner components for full relining jobs. These aren’t upsell items - they’re the materials we specify when the camera shows us your flue condition and we write the scope. Because we procure through a centralized buying network rather than marking up retail parts, the price you get in writing reflects actual material cost plus labor, not a padded parts bill.
Common Chimney Repair Problems We See in Andover Homes
- Original unlined or clay-tile flues in Shawsheen Village. The 1910s-1920s American Woolen Company brick homes on Burnham Road and Morton Street were built before modern flue liner standards. Decades of freeze-thaw cycling have spalled and cracked the original clay tiles, letting creosote and moisture penetrate mortar joints and degrade the brick face. A Level 2 camera inspection is the only way to see this damage.
- Multi-flue stacks with one flue relined and another ignored. Larger Andover colonials often have two or three fireplaces sharing a single chimney stack. Homeowners get one flue relined after a problem, assume the others are fine, and never learn that the adjacent flue has first-degree creosote and cracked tiles until a camera inspection reveals it. We assess every flue in the stack.
- Appliances vented into unlined chimneys. Furnaces and water heaters retrofitted into Andover’s oldest center-corridor homes vent corrosive flue gases that dissolve mortar in the smoke chamber and damper area. The damage is hidden from view and progresses until the chimney fails or carbon monoxide risk becomes acute. Camera inspection finds it before that point.
- Crown failure leading to systemic water damage. The concrete crown at the top of the chimney is supposed to shed water away from the masonry below. In Andover, crowns without proper reinforcement, slope, or drip edges crack within a decade, letting water saturate the brick below. We see this pattern repeatedly on 1980s-era colonials with original construction crowns.

FAQs - Chimney Repair in Andover
Yes. Original clay-tile flues in Shawsheen Village’s 1910s-1920s construction have endured a century of freeze-thaw cycling, and the tiles spall and crack in ways you cannot see from the firebox or roof. Our Level 2 inspection camera shows the actual flue condition, and we provide the footage and a written assessment before recommending any work. Call (351) 444-9705 to schedule - estimates are free.
The distinction comes down to how deep the deterioration runs. Repointing fixes failed mortar joints while the brick itself remains sound; rebuilding is necessary when spalling, cracking, or structural shifting has compromised the masonry mass. Our camera inspection and exterior assessment document exactly what we found, show you the photos, and give you a written price for each option so you can decide. Nothing is recommended without evidence you can see.
That’s efflorescence - mineral salts left behind when water migrates through the masonry and evaporates at the surface. In Andover, it typically indicates a failed crown, deteriorated pointing, or improper flashing that’s letting water into the stack. The staining itself is cosmetic, but the water movement behind it is actively degrading your mortar and, in freezing weather, spalling your brick. We find the water source during inspection and fix it before cosmetic cleaning.
In Shawsheen Village especially, yes. Our field experience on Burnham Road and Morton Street shows that identical 1920s construction means identical flue-age problems. One camera inspection on the block routinely exposes the same deteriorated clay-tile liners and mortar issues in five or six neighboring homes. If your neighbor’s chimney needed liner work, yours was built the same year with the same materials and the same exposure. A Level 2 inspection will tell you where you stand.
Third-degree (glazed) creosote cannot be brushed out with standard sweeping. It’s a hardened, tar-like deposit that requires mechanical removal with specialized chains or rotary tools, and in severe cases chemical treatment to soften it first. In Andover’s long heating season, we see this most often in wood-burning fireplaces that burn unseasoned wood or are damped down overnight. The removal itself is only part of the job - we also camera-inspect to find why the creosote accumulated so heavily, whether that’s an undersized flue, improper appliance connection, or deteriorated liner. Call (351) 444-9705 for an inspection and written scope.
