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.

AfterChimney Cleaning in Waltham, MA
Chimney cap and crown work in Waltham usually runs $450 to $1,900 depending on whether we’re replacing a rusted cap, rebuilding a cracked crown, or both. Our crews see a pattern across Waltham’s Watch City mill-era neighborhoods: original brick chimneys with concrete crowns that were poured decades ago, now spider-cracked from freeze-thaw cycles and shedding water into the flue. Call (857) 567-8887 for a written quote before any work begins.
Why Waltham Homes Are Different
Waltham’s dense worker housing, built from the 1870s through the 1920s for Waltham Watch Company and Charles River mill employees, left the city with a high concentration of original masonry chimneys sized for coal-burning systems. Nearly all of those systems have since been converted to oil and, increasingly, to gas. Each conversion left liner dimensions mismatched for the appliance now attached, and that mismatch shows up as weak draft, backdrafting, or cracked clay tile liners. Neighboring Lexington and Weston don’t face this at the same rate because their housing stock is younger and purpose-built for modern fuels.
Waltham also sits in the Charles River valley with a full six-month heating season. Chimneys here bear sustained creosote accumulation from October through April, and the freeze-thaw cycles at this latitude work hard on mortar joints and brick crowns. Heavy snowpack and ice damming along Moody Street and the South Side routinely compromise flashing and drive water into liners between cleanings.
Our Main Waltham Services
Most Waltham homeowners reach out about one of three things: a chimney that hasn’t been cleaned in years, a water stain spreading across the ceiling, or a fireplace that smokes back into the room. Here’s what each involves locally.
Chimney Cleaning & Sweep in Waltham
In Waltham’s older core, a cleaning usually reveals more than soot. We document what we find with a camera scan as part of every visit, because the original clay liners in these homes are often cracked or spalled after a century of heat cycling. The work includes removing creosote from the flue and smoke chamber, checking the damper, and giving you a photo record of what the inside actually looks like. Full details are on our Chimney Cleaning & Sweep in Waltham page.
Chimney Repair in Waltham
Waltham’s triple-deckers and late-Victorian cottages share flues more often than homeowners realize, and a deteriorating shared flue is a compliance issue under Massachusetts fuel gas code liner-sizing rules. We handle brick repair, crown rebuilds, flashing replacement, and smoke chamber parging. Every repair is quoted in writing before work starts, with photos showing exactly what’s damaged. See the specifics on our Chimney Repair in Waltham page.
Fireplace Services in Waltham
Most Waltham fireplaces were built for coal and converted later, which means the firebox dimensions and damper assemblies aren’t always right for modern wood burning. We repair and replace dampers, rebuild fireboxes, and resolve smoking issues that come from draft problems rather than the fireplace itself. Our Fireplace Services in Waltham page covers what we check and what each repair involves.

BeforeAfterChimney Cap & Crown in Waltham
Chimney cap and crown work in Waltham comes down to protecting the top of the chimney from New England weather. A cracked crown lets water seep into the brick below, and once that freeze-thaw cycle starts, spalling and flue damage follow within a season or two. We replace rusted caps, rebuild failed crowns, and coat intact crowns to buy them another decade. This is the repair Waltham’s triple-deckers need most often, and you can see more about how we handle it on our Chimney Cap & Crown service page.
Cap Installation
Signs you need it
You see rain streaking down the flue during storms, or birds and squirrels are getting in.
What it costs in Waltham
Cap installation in Waltham typically runs $300 to $600 depending on flue size and material.
How we do it
We measure the flue, select a stainless or copper cap, secure it with a mechanical fastener, and photograph the finished install.
Crown Repair
Signs you need it
You notice cracks in the concrete top, missing chunks on the ground below, or white efflorescence on the brick.
What it costs in Waltham
Crown repair in Waltham typically runs $450 to $1,200 depending on crack severity and whether we rebuild or coat.
How we do it
We remove loose material, form a new crown with a proper drip edge, and apply a waterproof membrane before documenting the result.
Crown Coating
Signs you need it
Your crown is intact but porous, with hairline cracks that have not yet opened up.
What it costs in Waltham
Crown coating in Waltham typically runs $350 to $700 and is the right call when the crown is structurally sound.
How we do it
We clean the surface, apply a flexible elastomeric coating, and give you a written record of the product and coverage.
What Chimney Cap & Crown Costs in Waltham
| Item | Typical range in Waltham |
|---|---|
| Cap installation | $300 - $600 |
| Crown repair | $450 - $1,200 |
| Crown coating | $350 - $700 |
Can a cracked crown wait until spring?
It can wait if the crack is superficial, but Waltham’s freeze-thaw cycles widen small cracks fast. A crown that’s actively letting water through will cost more to fix in April. Call (857) 567-8887 for a camera inspection.
Do you need a permit for cap work in Waltham?
Cap replacement typically doesn’t require a permit in Waltham. Crown rebuilds are routine exterior masonry work. We’ll tell you if anything about your setup changes that. Call (857) 567-8887 for a written assessment.
Chimney Liner & Rebuild in Waltham
Waltham’s fuel conversions created a specific problem: original flues sized for coal furnaces now venting gas appliances with much smaller exhaust volumes. That mismatch leads to condensation, deteriorated clay tile, and draft failures. We install stainless steel liners sized to the appliance, and we rebuild chimneys when the masonry itself has gone too far. Our Chimney Liner & Rebuild page walks through the full scope.
Stainless Steel Liner
Signs you need it
Your gas furnace or water heater shares a flue with another appliance, or the clay liner is cracked and flaking.
What it costs in Waltham
Stainless steel liner installation in Waltham typically runs $2,500 to $5,000 depending on height and accessibility.
How we do it
We size the liner to the appliance using Massachusetts 248 CMR rules, lower it down the flue, insulate it, and connect it at the breach.
Partial Rebuild
Signs you need it
The top few courses of brick are spalled or loose, but the rest of the chimney is structurally sound.
What it costs in Waltham
Partial rebuilds in Waltham typically run $1,500 to $3,500 depending on how many courses come down.
How we do it
We remove deteriorated brick, match the existing mortar and brick size, rebuild in lifts, and tool the joints to shed water.
Full Chimney Rebuild
Signs you need it
Brick is spalling from the roofline down, or the chimney leans, or a camera scan shows the flue has collapsed inward.
What it costs in Waltham
Full chimney rebuilds in Waltham typically run $6,000 to $15,000 depending on height, access, and whether scaffolding is required.
How we do it
We take the chimney down to the roofline or below, rebuild it with new flue liners where required, and install a new cap and crown.
What Chimney Liner & Rebuild Costs in Waltham
| Item | Typical range in Waltham |
|---|---|
| Stainless steel liner | $2,500 - $5,000 |
| Partial rebuild | $1,500 - $3,500 |
| Full chimney rebuild | $6,000 - $15,000 |
Do I really need a new liner if my chimney looks fine outside?
In Waltham’s older homes, the outside can look perfect while the clay liner is cracked and shedding into the flue. The only way to know is a camera scan. Call (857) 567-8887 for one.
How long does a rebuild take on a triple-decker?
Most partial rebuilds finish in a day. A full rebuild on a three-story Waltham triple-decker takes two to four days. You get a written timeline before we start.

What Waltham Customers Say
"They told me the flue was fine and I did not need a liner. Charged me for the inspection and nothing else. That is why I have called them twice since."
- Hal M."Found a bird nest and a blocked flue we had no idea about. Photographed everything, cleared it, and explained what the smell had been."
- Curtis V."They ran a camera down the flue and showed me the cracked tiles on a screen. The previous company had swept it twice and never mentioned it."
