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.

AfterFast, Reliable Chimney Repair Across Burlington
Chimney repair in Burlington typically runs $350-$1,800 for common fixes like mortar repointing, flashing repair, and minor brickwork, while full flue liner resurfacing lands between $3,200 and $5,900. Most repairs we scope here are tied to one thing: oil-era chimneys from the 1960s and 70s that were never properly relined after the home switched to gas. Our camera-scan inspection (NFPA 211 Level 2) documents exactly what needs work before anyone quotes a dollar. Call (857) 567-8887 and we’ll walk you through what we’re seeing.
We’re in Burlington several days a week, scoping chimneys off Winn Street, Cambridge Street, and the neighborhoods around Simonds Park. You don’t need to describe the problem perfectly. You need someone to put a camera down the flue and show you the evidence. That’s what we do.
Why Level Two Chimney Boston Is Burlington’s Preferred Chimney Repair Company
Burlington homeowners call us because our default inspection standard is the same one code inspectors use: NFPA 211 Level 2, camera down the flue, written price before work starts, and a documented photo record when it’s done. Since 2009, we’ve completed more than 38,000 chimney inspections and cleanings. The majority of our Burlington work is on the ranch, Cape, and split-level stock built during the Route 128 boom, and we know exactly what those chimneys do when the liner fails.
Every Burlington job is quoted in writing before anything is touched. That’s Clause 1 of the Haven Standard, and it means you see the scope, the price, and the warranty in writing before a technician starts work. We don’t ask you to trust a verbal estimate. We hand you the document and let the camera footage speak. On a split-level off Mill Street, our tech scoped a 1968 chimney after the homeowner noticed spalling bricks near the crown. The clay tile flue was original, cracked, and roughly twice the cross-section needed for their 2012 gas boiler. Condensate had eaten the mortar joints from the inside. We showed them the footage, pulled a HeatShield resurfacing permit, and repaired the flue liner without rebuilding the stack. That’s the standard on every visit, and it’s why our 365-Day Done Right Promise gets stamped on every job.
When you call, a live person answers. Your tech arrives uniformed, background-checked, with a license number on the page. Corrine Halstead leads our team and holds the line on documented evidence before recommendations. We serve Burlington locally from our Boston dispatch office, which means scheduling is fast and consistent.
Our Chimney Repair Services in Burlington
Mortar Repointing
Mortar repointing in Burlington typically runs $350-$900 depending on how many courses of brick need tooling. The freeze-thaw cycling through late winter and mud season opens joints that were tight the previous fall. We don’t just rake and fill; we match the original mortar’s compressive strength so the repair doesn’t transfer stress into the brick itself.
Spalling Brick Repair
Spalling brick in Burlington usually lands between $450 and $1,400, depending on the face area and how deep the brick faces have popped. The root cause here is rarely just weather. It’s often acidic condensate from a gas appliance venting into an oversized oil-era flue, which accelerates liner deterioration from the inside while seasonal water intrusion spalls the face from the outside. We show you the camera footage of the inside before recommending any outside work.
Chimney Waterproofing
Waterproofing a Burlington chimney costs $185-$400, and it’s the one repair that pays for itself through fewer reopening joints each spring. We use siloxane-based treatments that block water while letting the chimney breathe. Burlington’s inland climate means repeated saturation and freezing, so we only use waterproofers rated for New England masonry.
Flashing Repair
Flashing repair in Burlington runs $400-$1,200, and it’s one of the most common leak sources we find on ranch and split-level chimneys. The geometry doesn’t help: shallow roof pitches and side-wall abutments where chimneys penetrate near dormers add stress. We replace step flashing, counterflashing, and the base flashing in one pass, then document the old material in the photo record.

We work with materials from Gelco, Olympia Chimney, and Copperfield, sourced through the Haven buying network to keep pricing honest for Burlington customers. We stock the common replacement parts locally: clay tiles, crown sealant, stainless caps, and the stainless steel liners used in HeatShield resurfacing. That means most jobs don’t get delayed waiting on a supply house.
Common Chimney Repair Problems We See in Burlington Homes
- Clay tile liners past design life. Most Burlington chimneys built in the 1960s and 70s have never been camera-inspected since original construction. The first sign is often spalling bricks or a draft problem, not a visible crack.
- Acidic condensate from post-conversion gas appliances. When a 1968 oil-fired chimney vents a modern gas boiler, the flue is often oversized, and the cooler exhaust causes acidic condensate that erodes mortar and tile from the inside out.
- Freeze-thaw damage through mud season. Burlington’s winters push water into open mortar joints, and the repeated freezing expands them. Spring inspections routinely show joints that were solid the previous fall.
- Crown and flashing failures at the roofline. Ranch and split-level chimneys in Burlington frequently leak where the chimney penetrates near a valley or dormer, and the crown gets the worst of the runoff splash.

FAQs - Chimney Repair in Burlington
Spalling after repointing usually means the problem is inside the flue, not on the brick face. Your oil-era clay tile flue is almost certainly oversized for a gas appliance, which lets acidic condensate form and erode the mortar from behind. The spalling you see outside is often the second symptom. Until the liner is resized or resurfaced, repointing alone won’t hold. A camera scan settles it in minutes. Call (857) 567-8887 and we’ll show you exactly what the inside of that flue looks like.
Yes, especially in Burlington, where the most expensive problems are invisible from the ground. A clay tile flue can be cracked in a dozen places while the exterior brick looks untouched. A camera inspection is the only way to see liner condition, clearance, and whether the flue matches the connected appliance. We include a camera inspection on every visit and hand you the photo record afterward. It’s not an upsell. It’s the inspection.
Freeze-thaw cycling pushes water into any open mortar joint, expands it when frozen, and opens the joint further. By late March, chimneys that sealed fine in October can show fresh spalling and open joints. Burlington’s inland winters produce this cycle repeatedly. A spring inspection after the last hard freeze catches the damage before a summer rain turns it into a leak. We schedule Burlington spring inspections in advance since that’s when we find the most repointing and waterproofing need.
Likely yes. Massachusetts building code (780 CMR) requires proper chimney liner sizing for the connected appliance, and a gas unit venting into an unlined or oversized oil-era flue is out of compliance. The fix is usually a resized stainless liner or HeatShield resurfacing, not a full rebuild. We show you the current condition on camera, explain what code requires, and quote the liner work in writing before anything starts.
What you’re seeing is acidic condensate residue, not creosote from wood smoke. It forms when gas exhaust cools too much in an oversized flue, condenses on the clay liner, and builds up a tarry film that eats mortar from the inside. Burlington’s converted oil-era chimneys are especially prone to this because the flue was sized for oil, not gas. A camera scan confirms the film, and we recommend liner resurfacing or resizing based on the footage, not a guess.
