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 Top Hat Chimney Is North Andover’s Preferred Chimney Repair Company
Wendell Pike founded Top Hat Chimney in 1999, and he’s been inside more North Andover chimneys than he can count since. The houses here are different from what you find ten minutes down the road in Andover or Lawrence. We know the colonial-era stacks off Salem Street and Osgood Street, the mid-century ranches up near Berry Street and Chestnut Street, and the split-levels scattered along Route 125. That local knowledge matters when you’re diagnosing why a 200-year-old flue suddenly won’t draft or why water keeps finding its way past flashing that looked fine last fall.
Every job we do in North Andover carries the 90-Day Done Right Promise in writing. If the repair isn’t right, one call brings Wendell back. No fine print, no arguing. And when you call (978) 724-7935, a live person answers. It might be Wendell himself picking up at 9 p.m. on a Sunday. Ask anyone on your street what they got from the last big chimney outfit that rolled through; then ask someone who used Top Hat.
Our Chimney Repair Services in North Andover
Mortar Repointing
Older North Andover brick, especially the lime mortar used in the 18th-century homes near the Old Center, erodes from the inside out after decades of Merrimack Valley freeze-thaw cycles. Mortar repointing in this area typically runs $800 to $1,400 for a standard repair section, and it’s the single most common job we do in North Andover. We match the mortar color and composition to the original work so the repair doesn’t look like a patch. If we’re working on a home in the Historic District, we take extra care to match the existing lime putty rather than slapping on modern Portland cement that would trap moisture inside the brick.

Spalling Brick Repair
When brick faces start popping off and littering your roof or walkway, that’s spalling. North Andover’s tight street setbacks near the Old Center mean many chimneys never got the flashing and crown attention they needed, and water has been soaking into the soft, aged brick for years. Spalling brick repair in North Andover usually falls between $1,000 and $2,200 depending on how much masonry has to be cut out and replaced. Wendell will show you camera footage of the damage before he recommends anything, so you’re never paying for a rebuild you didn’t actually need.

Chimney Waterproofing
North Andover sits in the Merrimack Valley corridor, which channels nor’easters right through town. That repeated hard freeze-thaw cycle is brutal on brick that’s already been wicking moisture for a century or two. We apply a vapor-permeable waterproofing treatment after repointing or brick repair, so moisture can escape from inside the masonry but rain and snow can’t soak in from outside. A typical chimney waterproofing in North Andover runs $400 to $800 on top of the underlying masonry repair. It’s the single cheapest thing you can do to stop a repointed chimney from failing again in five years.

Flashing Repair
Flashing is the sheet metal where the chimney meets the roof line, and on North Andover’s colonial homes it’s often original copper that’s been patched with tar and roofing cement by three generations of homeowners. When flashing fails, water runs down the chimney chase and into the attic, the wall cavity, or the ceiling around the fireplace. Flashing repair in North Andover typically costs $450 to $900, and we replace it with proper step flashing and counter-flashing rather than gooping on another layer of caulk. Tight roof access near the Old Center means this job gets skipped more often than it should. We bring ladders sized for the job and call you with a real arrival window if anything slips.

Trusted Brands We Service in North Andover
If your chimney has a liner that needs replacing, a crown that needs rebuilding, or a tricky flashing detail, we work with HeatShield, DuraFlex, and Gelco products because they hold up under New England weather. The sweep who shows up at your door will have what’s needed on the truck most days, which means less waiting around for a second visit. We don’t push a brand on you. We’ll tell you what your existing setup is, what’s failing, and whether a HeatShield resurfacing job actually makes sense, or whether a full DuraFlex stainless liner is the honest answer. The camera footage and a plain-English verdict, every time, no exceptions.
Common Chimney Repair Problems We See in North Andover Homes
- Shared and adjacent flues in colonial-era homes: On a side street off Great Pond Road near the Old Center, our crew repaired a 1790s colonial where a neighbor’s wood stove had been venting into a shared two-flue stack for years. The clay tile liner in our client’s flue was spalled and collapsed, so we removed the debris, installed a DuraFlex stainless steel liner, and repointed the spalling brick above the roofline to stop cross-contamination and restore draft.
- Failed mortar joints from freeze-thaw cycling: North Andover’s winter temperature swings are hard on soft colonial brick. Water gets into hairline cracks, freezes, expands, and pops the joint open further. After enough seasons, you’re looking at repointing or, in what we see a lot around the Old Center, partial chimney rebuilding.
- Collapsed clay tile liners: The 18th- and early 19th-century chimneys in North Andover were built without modern liners, or with clay tiles that have since cracked and collapsed under decades of heat stress. A collapsed liner is a code violation and a carbon monoxide risk. We see it flagged constantly during pre-sale inspections.
- Wood stove inserts with undersized or short flex liners: Mid-century ranch and split-level homes along Route 125 and up near Berry Street often had wood stoves retrofitted into oversized masonry flues. The flex liners were never sized right or never extended to the cap, which kills draft and causes smoke rollout. This is one of the most common repair finds during North Andover real estate transactions.

FAQs - Chimney Repair in North Andover
Yes. In a shared two-flue stack, an unlined or failed flue on one side can bleed exhaust into the other side’s flue and even into the neighboring home’s living space. We bring both homeowners in on the camera inspection, document every flue’s condition separately, and if the stack needs to be relined, we sometimes have to reline more than one flue to get the whole assembly safe and code-compliant. Call (978) 724-7935 and we’ll walk you through what your shared stack actually looks like inside.
Because most of them were built before modern chimney liners existed, and over 200-plus years the clay tile liners that were added later have cracked, spalled, or collapsed entirely. Home inspectors in Essex County routinely red-flag unlined flues as a Massachusetts code violation, and sellers get stuck needing a reline before closing. That’s the single biggest driver of our late-summer and fall work in North Andover. We’ve seen the same scenario play out dozens of times near the Old Center.
Most of the time, yes. Tight setbacks near the Old Center make straightforward roof access tricky, but we bring ladders sized for narrow side yards and can often work from below or from a neighboring property with permission. The repair itself doesn’t change; it’s just a matter of getting to the stack safely. If we truly can’t access the chimney on a narrow lot, we’ll tell you plainly and figure out the next step rather than leaving the job half-done.
Flexible stainless liners that were installed for wood stove inserts but never sized correctly or never extended all the way to the chimney cap. That causes draft failure, smoke rollout into the living space, and a failed pre-sale inspection more often than not. The fix is usually a correctly sized and fully extended liner, which runs $2,200 to $5,000 in North Andover depending on the flue size and access. We’ll show you the camera footage before recommending anything.
Homes on large, wooded lots around the Lake Cochichewick watershed tend to burn more locally cut firewood, and green or improperly seasoned wood accelerates creosote buildup dramatically. That means stage-two and stage-three creosote glazing forms faster, which in turn means more frequent sweeping and more repair work when the acidic creosote starts eating at the masonry and mortar. If you’re burning wood from your own lot, have the flue checked once a year, burn or no burn.
If your chimney needs work in North Andover, call (978) 724-7935 and talk to a real person. Wendell will give you a straight answer about what’s wrong, what it costs, and whether it can wait. Estimates are free, and no one is going to pressure you into a repair you don’t need.
