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 Liner & Rebuild Across Burlington
Chimney liner replacement and partial rebuilds in Burlington, MA typically cost between $2,800 and $6,500 depending on flue count, liner material, and whether masonry work is needed. Most jobs are completed in a single visit after a Level-2 camera inspection confirms the scope. If you’re smelling gas near your fireplace, seeing water stains around the chimney chase, or your technician flagged cracked clay tile during a cleaning, your chimney likely needs relining or rebuild work, not just a sweep.
We’ve been dispatching crews to Burlington from our Boston office for decades. We know the split-levels off Route 3A, the colonials near the Burlington Mall, and the raised ranches tucked behind Wilmington Road. These homes share a common problem: chimneys built during the 1960s-1980s suburban boom, now with clay tile liners that have endured fifty-plus years of hard Massachusetts winters. When you call (781) 404-3793, a live person answers, day or night. We’ll schedule a camera inspection, show you the photos, and give you a plain-English verdict with upfront pricing before any work begins.

Our Chimney Liner & Rebuild Services in Burlington
Stainless Steel Liner Installation
Stainless steel liners are what we install most often in Burlington, and for good reason. The town’s 1960s-70s oil-to-gas conversions left many oversized clay flues serving low-heat gas appliances without relining, and because Burlington sits inland with no coastal moderating effect, those flues run cold and chronically condense. A correctly sized stainless liner, typically DuraFlex, solves the draft problem and meets modern code. A single-flue stainless installation in Burlington generally runs $2,800-$4,200; two-flue colonials common off Lexington Street run $4,000-$5,800.
Flexible Liner Systems
Not every Burlington chimney has a straight shot. The offset flues in split-levels near Pinehurst and the older colonials around the Town Common often need a flexible liner that can navigate bends without breaking the draft. Flexible systems cost roughly the same as rigid stainless when the flue is straightforward, but add $400-$800 for complex offsets. We measure with a camera first so you’re not paying for more than you need.
Liner Replacement
Full liner replacement becomes necessary when clay tile has spalled, shifted at the offset, or cracked from decades of freeze-thaw cycling. Burlington’s inland location means harder winters than coastal towns, with sustained subfreezing temperatures that accelerate mortar joint deterioration. We remove the damaged liner, inspect the smoke chamber and firebox, and install a new system sized precisely for your appliance. Liner replacement in Burlington typically falls between $3,200 and $5,500 depending on flue count and whether the smoke chamber needs parging.
Partial Chimney Rebuild
Sometimes the liner failure is a symptom, not the disease. Water intrusion through cracked crowns or failed flashing rusts the damper, degrades the smoke chamber, and undermines the liner from the outside. In Burlington, we see this pattern repeatedly in early spring cleanings: ice loading at the crown melts, finds a crack, and runs behind the flashing all winter. A partial rebuild addresses the crown, upper courses of brick, and flashing while the liner is being replaced. Partial rebuilds with liner work in Burlington range from $4,500 to $6,500.

Trusted Brands We Service in Burlington
We don’t use builder-grade substitutes. Our trucks carry DuraFlex stainless liners, HeatShield cerfractory resurfacing products, and Famco caps and fittings so Burlington customers aren’t waiting on parts. When we find a degraded smoke chamber or spalled clay during your Level-2 inspection, we can often complete the repair same day because the right materials are already on the truck. This matters in Burlington’s older neighborhoods where a second trip means another morning of taking off work.
Common Chimney Liner & Rebuild Problems We See in Burlington Homes
- Oversized, unrelined clay flues in converted oil-to-gas homes. Burlington’s 1960s-70s housing stock frequently went from oil to natural gas without relining. The oversized clay flue runs too cold for low-heat gas exhaust, causing chronic condensation, liner spalling, and draft failure that cleaning alone cannot fix.
- Freeze-thaw damage to crowns and mortar joints. Burlington’s inland climate produces harder freeze-thaw cycling than coastal Massachusetts towns. Crown cracks let meltwater penetrate, which refreezes, expands, and opens the crack wider each season. By March, we’re documenting significant water intrusion in chimneys that looked fine in October.
- Creosote buildup masking unsafe liner conditions. Decades of wood burning in Burlington fireplaces leaves first- and second-degree creosote in smoke chambers and flue offsets. Routine sweeping removes the creosote but often reveals the real problem: shifted clay tile, gaps at the offset, or a liner that has separated from the appliance connector.
- Original clay tile liners reaching end of service life. The clay tile in 40- to 60-year-old Burlington chimneys was never designed for indefinite use. We regularly find tiles that have cracked at the offset, shifted from thermal cycling, or spalled from condensation exposure, creating paths for heat and carbon monoxide to escape into the chase.
Pricing for Chimney Liner & Rebuild in Burlington, MA
Here is what chimney liner and rebuild work actually costs in Burlington’s market. These are the ranges we quote after camera inspection, with the number on the estimate matching the number on the invoice.
| Service | Typical Range in Burlington |
|---|---|
| Single-flue stainless steel liner | $2,800 - $4,200 |
| Two-flue stainless steel liner | $4,000 - $5,800 |
| Flexible liner with offset navigation | $3,200 - $5,000 |
| Full liner replacement (clay removal, new system) | $3,200 - $5,500 |
| Partial rebuild with liner (crown, upper brick, flashing) | $4,500 - $6,500 |
| Smoke chamber parging with liner work | $800 - $1,400 |
What moves the price? Flue count is the biggest factor. Two-flue colonials are common in Burlington and nearly double the liner material. Offset complexity adds labor. Smoke chamber damage found during inspection adds parging work. We never recommend work without camera evidence you can see yourself, and we’ll tell you plainly when something can safely wait.

FAQs - Chimney Liner & Rebuild in Burlington
Cleaning removes creosote and debris, but it cannot fix an oversized clay flue that was never relined after your oil-to-gas conversion. The flue is too large for modern gas appliances, so exhaust cools too quickly, condenses on the clay tile, and causes chronic draft failure and liner degradation. A correctly sized stainless liner restores proper draft and meets current fuel gas code. Call (781) 404-3793 and we’ll camera-inspect to confirm whether your flue is oversized.
Burlington chimneys should be inspected annually and swept as needed, but the harder freeze-thaw cycling here means crown and flashing damage can develop between cleanings. We recommend a Level-2 camera inspection any time you change fuel types, install a new appliance, or notice draft problems, water stains, or odors. The inspection includes photos you can see and a plain-English verdict on whether your liner is still sound.
Third-degree creosote is a hardened, tar-like deposit that standard sweeping cannot fully remove. It indicates a long period of cool, smoky fires or a liner that is too large for the appliance, both common in Burlington’s older fireplaces. Third-degree creosote is a significant fire hazard and usually requires chemical treatment or removal, plus evaluation of whether the underlying liner is still intact. We document the extent with camera photos and explain whether relining is the safer long-term solution.
Each flue is evaluated separately. The furnace flue is more likely to need relining if it was converted from oil to gas without updating the liner size. The fireplace flue may be sound or may have damage from wood-burning use, water intrusion, or age. Our Level-2 inspection checks both flues with separate camera runs, and we only recommend work on flues that show documented damage or code violations. You’ll see the photos for each.
Galvanised steel caps and flashing have a shorter lifespan than stainless in any climate, but Burlington’s combination of hard freeze-thaw cycling and acidic condensation from gas exhaust accelerates the corrosion. We see rusted-through galvanised caps regularly on 1980s-era homes around the Mall area and near Wilmington Road. We install stainless caps and copper or stainless flashing as standard, which outlast galvanised by decades. The upgrade is typically $180-$340 per cap and pays for itself in avoided water damage.
We were called to a split-level on a quiet Burlington street where the homeowner kept getting a gas smell and poor draft at the fireplace. A Level 2 inspection showed the original 1960s clay flue had been left oversized after the oil-to-gas conversion, and the cold gas exhaust had degraded the liner and warped the damper. We installed a correctly sized DuraFlex stainless steel liner and a new stainless cap, and the draft problem cleared immediately.
Your chimney was built to last, but the liner inside it wasn’t meant to last forever. If you’re in Burlington and suspect your clay tile has seen better days, or your technician flagged something you couldn’t see for yourself, call (781) 404-3793. A live person will answer, we’ll schedule a camera inspection, and you’ll get photos, a plain-English verdict, and upfront pricing before any work begins. Done right, and we stand behind it.
