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.

Our Chimney Repair Services in Randolph
Mortar Repointing
The post-WWII brick chimneys across Randolph’s North Main Street corridor and the neighborhoods near Crawford Square have mortar joints that have endured 50 to 70 years of Massachusetts freeze-thaw cycling. When the mortar crumbles, water penetrates the wall, accelerates deterioration, and can destabilize the entire structure. We grind out failed joints to proper depth and repoint with color-matched, professional-grade mortar formulated for New England’s climate. Most Randolph repointing jobs run $1,200-$2,400 for a standard single-flue chimney.

Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is epidemic in Randolph’s mid-century housing stock. The combination of original clay-tile liners cracked by condensation, failed crowns letting water in, and repeated freeze-thaw through inland Norfolk County winters destroys brick from the inside out. We replace spalled bricks with matching units, address the underlying moisture source, and seal the repair, including Chimney Cap & Crown - Randolph work when needed. On a recent job near the intersection of Route 28 and North Main Street, we found a 1965 Cape Cod chimney with bricks so deteriorated the homeowner could pull fragments loose by hand. We rebuilt the upper courses, installed a Gelco cap, and stopped the cycle. Typical spalling repair in Randolph: $800-$1,800.

Chimney Waterproofing
Many Randolph homeowners assume brick is waterproof. It isn’t. The town’s older chimneys absorb rainfall like a sponge, and once water is inside, freeze-thaw does the rest. We apply vapor-permeable waterproofing agents that let the chimney breathe while repelling liquid water - critical in Randolph, where the northern neighborhoods near the Blue Hills elevation see stronger winds driving rain deeper into masonry. Waterproofing a standard Randolph chimney runs $450-$850 and extends service life significantly.

Flashing Repair
The junction where chimney meets roof is the most leak-prone point on any Randolph home. Original step flashing on 1960s and 1970s ranches was often minimal, and decades of thermal movement have opened gaps. We fabricate and install custom flashing using professional-grade materials, sealed with counterflashing integrated into the masonry. Because many Randolph homes have low-profile chimneys with minimal clearance, flashing takes more abuse from wind-driven rain than in taller-chimney communities. Repair typically runs $400-$900; full replacement on complex roofs can reach $1,400.

Trusted Brands We Service in Randolph
We don’t use builder-grade substitutes. Every repair in Randolph is built with professional-grade materials from brands that the trade relies on: Gelco caps and accessories, Olympia Chimney liners and components, and Famco hardware. We stock common sizes and configurations locally, so most Randolph repairs don’t wait on shipping. When a HeatShield cerfractory flue liner repair is the right solution for a cracked clay flue, we have the equipment and certification to do it in a single visit. The materials matter, but so does the judgment to match the right product to the specific failure pattern - and Randolph’s oil-to-gas conversion chimneys present patterns that generic approaches miss.
Common Chimney Repair Problems We See in Randolph Homes
- Cool, wet oversized flues from fuel conversions. Randolph’s 1950s-1970s Cape Cods and raised ranches were built with single-flue brick chimneys sized for oil boilers, and many homeowners who later switched to gas or heat pumps now heat that oversized flue so weakly that it runs cool and wet year-round - cracking clay liners and building creosote even in houses that almost never burn wood.
- Freeze-thaw destruction of mortar and brick. Randolph’s inland Norfolk County location delivers repeated freeze-thaw swings through winter, which aggressively attacks aging mortar joints and cracked clay tiles in the town’s mid-century chimneys. The northern edge of town sits close to the elevated terrain of the Blue Hills, exposing those neighborhoods to stronger prevailing winds that drive rain and ice deeper into chimney crowns and accelerate cap and flashing failure.
- Low-profile chimneys creating downdraft after re-roofs. Many of Randolph’s 1960s Cape Cods have low-profile chimneys that satisfy the minimum clearance rule only marginally; when owners re-roof with thicker modern shingle systems or add ridge caps, the effective clearance can drop enough to cause persistent downdraft and smoke rollback - a callback-complaint pattern technicians in town encounter repeatedly that rarely shows up in taller-chimney communities like neighboring Milton or Canton.
- Failed crowns and caps letting water into the core. Original concrete crowns on Randolph’s mid-century chimneys have shrunk, cracked, or separated from the flue tile, allowing water directly into the chimney structure. Combined with the town’s exposure to wind-driven rain, this produces the spalling and joint failure we see on inspection after inspection.

FAQs - Chimney Repair in Randolph
Yes, because in Randolph’s converted heating systems, the chimney is still working even when the fireplace isn’t. Gas furnaces and water heaters vent into that same flue, and an oversized oil-era flue running cool from gas exhaust will condense moisture, crack clay tiles, and deteriorate mortar whether you burn wood or not. We inspect chimneys serving any fuel type. Call (857) 597-5950 to schedule - estimates are free.
You see what we see. Every Level-2 inspection includes a camera run the full length of the flue, photos of the interior and exterior, and a plain-English verdict on our monitor while you’re watching. We were out on a raised ranch off North Main Street where a 1960s clay-tile flue serving a gas furnace had a cracked liner and rusted damper from years of cool, condensing exhaust. We ran a camera the whole length, showed the homeowner the wet crack and spalling tiles on our monitor, then Chimney Liner & Rebuild - Randolph options were discussed, and we HeatShield-lined the flue and repointed the crown rather than pushing a full rebuild. The draft came back within spec, the moisture smell went away, and the homeowner had seen every reason for every dollar before we touched anything. No camera evidence, no recommendation. That’s our rule.
Randolph’s specific housing stock and exposure. The town’s rapid 1950-1975 buildout produced dense concentrations of low-profile chimneys on Cape Cods and ranches, many now past 50 years of service. The northern neighborhoods catch stronger winds off the Blue Hills elevation, driving rain deeper into crowns and flashing than in more sheltered Canton. And Randolph’s oil-to-gas conversion rate has left more oversized, underheated flues producing condensation damage. Same county, different failure patterns. Call (857) 597-5950 for an inspection that accounts for Randolph’s specific conditions.
Repointing is what your chimney actually needs: removing deteriorated mortar to proper depth and installing new mortar that matches the original profile and color. Tuckpointing is a cosmetic technique using two contrasting mortar colors to create the illusion of fine joints - historically used on high-end brickwork, rarely appropriate for a functional Randolph chimney. If a contractor recommends tuckpointing, ask why. We repoint. Done right, and we stand behind it.
Very likely, and it’s a pattern we see repeatedly in Randolph. Many 1960s Cape Cods here had chimneys that barely met the 2-foot-above-10-foot clearance rule when built. Add thicker modern shingles or a ridge cap, and the effective height drops below what prevents downdraft. We measure actual clearance, evaluate the chimney’s position relative to roof peaks and nearby trees, and can often resolve it with a proper flue extension or cap configuration rather than a full rebuild. Camera inspection confirms the flue condition first. Call (857) 597-5950 - we’ll figure out what’s actually wrong.
