Call (844) 803-1545

We’ve been working on Grafton chimneys since the early 1980s, back when the North Grafton commuter-rail expansion was just getting underway and the big suburban colonial developments were still farmland, so if you need Chimney Cleaning & Sweep - Grafton, you’re calling a crew that knows this town block by block. That means we’ve watched the two distinct housing stocks in this single ZIP code age in completely different ways. The pre-WWII mill cottages and capes in South Grafton and Grafton Center have their own set of problems, entirely separate from the prefabricated fireplace systems installed in the 1995-2010 builds near the station. We know which is which before we pull up to the curb, and we carry the right materials for both. Call (844) 803-1545 and a live person will answer, any hour of any day.

Why Hearthstone Chimney Co. Is Grafton’s Preferred Chimney Repair Company

Grafton homeowners don’t call us because we’re flashy. They call us because we show up when we say we will, we explain what we found in plain English, and we put our guarantee in writing with no arguing. Over 42 years in business means we’ve repaired chimneys on Brigham Hill Road, along Route 140, and in the tight lots behind the South Grafton village center where access alone takes planning.

Our Chimney Repair team documents every inspection with Level-2 camera footage you can see yourself, followed by a written verdict that tells you exactly what is wrong, what it will cost, and what happens if you wait. No surprises on the bill. The number on the estimate is the number on the invoice.

We also know the local terrain. A chimney on a hillside near Lake Ripple faces different wind and water exposure than one in the flatter North Grafton subdivisions. That kind of local knowledge changes how we approach waterproofing and crown repair.

Our Chimney Repair Services in Grafton

Mortar Repointing

The freeze-thaw cycling in Grafton is among the most aggressive in Massachusetts, and the original lime mortar in those South Grafton mill-era chimneys was never formulated to survive six decades of it. We grind out deteriorated joints to proper depth and repoint with color-matched, breathable mortar that moves with the brick instead of fighting it. Most repointing jobs on a standard single-flue stack in Grafton run $850-$1,400 and are finished in one day.

Spalling Brick Repair

Spalling, the flaking and crumbling of brick faces, is what you see when water has already gotten inside the masonry and frozen its way back out. In Grafton Center’s older colonials, we regularly find spalling concentrated on the south and west faces where sun exposure creates rapid temperature swings after wet weather. We remove damaged brick, match replacement units to the original, and address the water source so it does not repeat. Individual brick replacement starts around $350; partial rebuilds of spalled courses run $1,200-$2,200.

Chimney Waterproofing

Grafton’s 55-65 inches of annual snow sits on chimney crowns and soaks into porous brick through March and April, then refreezes on the first cold night. Our waterproofing treatment uses vapor-permeable sealers from professional-grade suppliers, applied after any needed repointing, so moisture can escape from inside but cannot enter from outside. A standard waterproofing treatment on a Grafton masonry chimney runs $600-$950 and carries a 10-year performance expectation when properly maintained.

Flashing Repair

The intersection where your chimney meets the roof is the most common leak point we find in Grafton, especially on the older homes with stepped flashing that has worked loose after decades of thermal cycling. We fabricate and install custom flashing with proper counterflashing integration, sealed with high-temperature compounds. Most flashing repairs in Grafton run $450-$850, and we warranty the workmanship under our 90-Day Done Right Promise.

For chimneys where the crown or cap is the primary failure point, we also handle Chimney Cap & Crown in Grafton with poured concrete crowns, pre-formed caps, and custom copper or galvanized installations.

Trusted Brands We Service in Grafton

We stock parts and materials from Olympia Chimney, Famco, and Copperfield on our Grafton-area trucks, which means most jobs do not wait on shipping. Olympia’s stainless flue liners and Famco’s ventilation components are what we specify for the oversized masonry stacks in South Grafton that need proper sizing for modern gas and oil appliances, and we handle Chimney Liner & Rebuild - Grafton jobs start to finish. Copperfield’s crown repair compounds and waterproofing agents handle the freeze-thaw punishment this town dishes out. When a North Grafton prefab fireplace needs a new chase cover or termination cap, we measure, fabricate, and install without the two-week delay you’d get from a contractor who orders everything from a catalog.

Common Chimney Repair Problems We See in Grafton Homes

• Crown cracks after February freeze-thaw. Every late winter, Grafton chimneys absorb snowmelt during the day and refreeze overnight. The crown, the concrete slab at the top of your chimney, takes the worst of it. Hairline cracks become water highways by April, and by October you’ve got interior ceiling damage.
• Oversized flues in South Grafton mill housing. Those handsome brick chimneys on Pleasant Street and near the old mill villages were built for coal furnaces with massive flue requirements. Modern gas and oil appliances exhaust into flues three times too large, causing acidic condensation that destroys clay tile from the inside. The masonry looks fine from the sidewalk. The inside is another story.
• Corroded chase covers on 1990s-2000s prefabs. The galvanized steel chase covers installed on North Grafton’s suburban colonials are hitting 20-30 years of service. Rust stains on the siding, water in the firebox, and deteriorated firestop gaskets are the signals. We replace with stainless or copper that outlasts the original by decades.
• Failed flashing at roof intersections. Grafton’s combination of heavy snow load and older roof geometries in the village cores creates chronic flashing separation. Homeowners often mistake it for a roof leak and pay for unnecessary shingle work when the real problem is the chimney-to-roof seal.
