We’ve been climbing Burlington chimneys since the early 1980s, back when the Route 128 tech corridor was still filling in the neighborhoods off Winn Street and Bedford Street with the split-levels and colonials that now dominate the town’s housing stock. Those homes were built fast, heated with oil, and their chimneys are now fifty to sixty years old. We know what fails on them, and we know the difference between a crown that needs patching and a crown that’s failed because the flue underneath it has been condensing flue gas for twenty years after a gas conversion nobody thought to reline.

Our Chimney Cap & Crown team documents every inspection with a Level-2 camera and photos you can see. Nothing gets quoted without evidence you can hold in your hand.

Why Hearthstone Chimney Co. Is Burlington’s Preferred Chimney Cap & Crown Company

Burlington homeowners tend to stay put. The tech professionals who bought these colonials in the 1990s are still in them, and their parents - the original 1960s buyers - are still calling us from the same raised-ranches off Terrace Hall Avenue and Fox Hill Road. That longevity matters. We’ve earned the calls we get from Burlington because we answer the phone with a live person, we show up when we say, and we don’t invent problems that aren’t there.

Our reviews from Burlington customers mention the same things: the technician pointed the camera at the flue and explained what we were looking at, the estimate matched the final bill, and when we had a question two weeks later, someone picked up the phone. Our 90-Day Done Right Promise is in writing with no arguing - if it’s not right, we come back. No paperwork to dig up.

Dispatch and scheduling are coordinated from our Boston office, but our crews serve Burlington locally. We’re familiar with the town’s permit requirements through the Burlington Building Department and the specific challenges of working on chimneys tucked against split-level rooflines with limited ladder access. Most jobs are completed in a single visit.

Our Chimney Cap & Crown Services in Burlington

Crown Repair

Crown repair is what we do most often in Burlington, and it’s rarely as simple as slapping on sealant. The original mortar crowns on 1960s-80s chimneys here were poured with a basic sand-cement mix and no reinforcement. After fifty-plus years of Burlington’s hard inland freeze-thaw cycles - no coastal moderation to soften the temperature swings - that mortar is spalled, cracked, or completely detached from the brick courses below.

We grind out the damaged material, inspect the flue with a camera while we’re at it, and pour a new Gelco crown with proper overhang and drip edge. If the flue liner underneath is cracked or offset from years of condensation after a gas conversion, we’ll show you that footage before we quote anything beyond the crown. A crown-only fix on a failing liner is money thrown away.

Cap Installation & Replacement

Single-flue caps on Burlington’s older chimneys are often the wrong size, rusted through, or missing entirely. Squirrels love the oak canopy along the Burlington Landlocked Forest edge, and a missing cap in November means a nest by December. We install stainless and copper caps from Famco and Copperfield, measured to your flue and secured with proper mounting hardware - not the bent-wire jobs that blow off in the first nor’easter.

But here’s the local reality: many Burlington caps we replace are on chimneys that also need relining. The oversized clay flue from the original oil furnace is now venting a lower-temperature gas appliance. That flue stays wet, the liner spalls, and the moisture attacks the crown from below while rain attacks from above. We check both. You see both.

Multi-Flue Cap

This is the right solution for most Burlington colonials and split-levels. Your chimney chase carries two flues - fireplace and furnace, or fireplace and an abandoned oil flue - and each needs its own protection. A multi-flue cap from Olympia Chimney covers the entire chase with a single stainless hood, mesh screening on all flues, and a profile that sheds ice and leaves.

We size these to your chase dimensions, not a stock catalog guess. On a recent job near the Burlington Mall, a homeowner had been quoted a single-flue cap by another company that would have left the furnace flue open to the weather. We measured both flues, showed the camera footage of the condensing flue gas damage inside, and set a custom multi-flue cap that solved the actual problem.

Custom Cap

Some Burlington homes need more than standard sizing. Steep-pitch roofs on the town’s 1970s contemporaries, or chimneys with unusual flue spacing from a later addition, require custom fabrication. We work with Copperfield and local sheet-metal shops to build caps that fit properly and last. Custom caps in Burlington typically run $650-$1,200 installed, depending on metal choice and access difficulty.

Crown Coating

For crowns with minor surface spalling and intact structural integrity, a professional-grade crown coating from HeatShield can add five to ten years of protection. We don’t recommend coating over cracks that go through to the flue, and we don’t coat without a camera inspection first. In Burlington’s climate, a coating on a compromised crown fails in two winters. We’ll tell you honestly which category you’re in.

Trusted Brands We Service in Burlington

We install caps and crowns built from professional-grade materials - no builder-grade substitutes that fail at the first hard freeze. Our stock includes stainless and galvanized caps from Famco and Olympia Chimney, custom copper work through Copperfield, and crown repair products from Gelco and HeatShield. We keep common Burlington sizes in our local inventory, so most cap replacements don’t require a two-week order delay. When your crown is leaking into the attic insulation, that matters.

Common Chimney Cap & Crown Problems We See in Burlington Homes

• Ice loading cracks the crown overhang. Burlington’s inland location means sustained subfreezing temperatures with no coastal moderation. Water that seeps into hairline cracks in the crown mortar expands with every freeze, and by March the overhang is spalling off in chunks. We find this on early spring cleanings every year, often with ceiling stains below that the homeowner noticed first.
• Gas-converted flues condense from the inside out. A significant share of Burlington’s 1960s-70s homes switched from oil to natural gas without relining the oversized clay flue. Lower flue-gas temperatures keep the stack wet year-round, softening mortar at the crown and causing clay tile spalling that a cap alone won’t fix. Our camera finds this routinely.
• Multi-flue chases with abandoned oil flues trap moisture. When one flue is capped but the other is left open, or when both are capped without proper venting, downdraft-driven moisture collects in the unused flue. Animal nests compound the problem. We see smoke chamber deterioration from the top down on chimneys near Simonds Park and the Town Common where this went unaddressed.
• Original flashing has separated from the brick. Fifty years of thermal cycling loosens step flashing at the chimney-roof intersection. Water runs behind it, shows up as a stain on the bedroom ceiling, and the homeowner calls us thinking it’s a roof leak. Sometimes it is. Often it’s the crown directing water exactly where it shouldn’t. We sort out which is which before anyone climbs onto the roof.
