We’ve been answering calls for Chimney Cleaning & Sweep - Millbury and repairs from homeowners for over 42 years.

When you call (844) 803-1545, a live person answers - day, night, weekend - and we’ll give you a real arrival window, not a four-hour guessing game. Most Millbury calls reach us within 25 minutes, and our trucks carry the materials to finish the job that day.
Why Hearthstone Chimney Co. Is Millbury’s Preferred Chimney Repair Company
Millbury sits in Worcester County’s interior, where winters bite harder and linger longer than they do closer to Boston. That freeze-thaw cycle you endure from November through April? It fractures mortar joints and pops brick faces with mechanical precision. We’ve watched the same pattern damage chimneys on Pleasant Street, on West Main, and in the older neighborhoods tucked between the Blackstone River and the canal. This isn’t theoretical for us. We’ve documented it with camera scopes and repaired it with materials rated for exactly this climate.
Our reputation here was built one job at a time. Homeowners in Millbury call us back because we show them photos they can understand, explain what failed and why, and quote a price that matches the final invoice. No phantom charges, no “we found something else” surprises.
Response time matters when water is entering your living room or a chimney crown has cracked wide enough to drop debris into your flue. Our technicians are background-checked, uniformed, and stocked with professional-grade materials from DuraFlex, HeatShield, and Famco. Most Millbury repairs are completed in a single visit because we don’t send a salesperson to look and a crew to return later. The person who diagnoses it fixes it.
We’re not a chain chasing volume, and we’re not a one-truck operator who might answer the phone next month or might not. Hearthstone Chimney Co. has served local communities since 1984. We plan to be here in thirty more years, and we act accordingly.
Our Chimney Repair Services in Millbury
Mortar Repointing
The mortar between your bricks is the sacrificial element - it’s supposed to erode before the brick does. In Millbury’s older housing stock, that mortar has been doing its job for 100 years or more, and it’s exhausted. We grind out deteriorated joints to proper depth and repack with color-matched, high-bond mortar formulated for central Massachusetts temperature swings. On homes near the Blackstone River corridor, we often find original lime mortar that has turned to powder; we match the replacement to the masonry era while meeting modern performance standards.

Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is epidemic in Millbury’s 19th-century chimneys. The soft, low-fired brick used in Blackstone Valley mill construction absorbs moisture more readily than modern hard-fired brick, and when that moisture freezes, it shears off the face in layers. Our Chimney Repair team removes damaged units, sources matching replacement brick where possible, and rebuilds with proper bonding patterns. In cases where the interior has deteriorated from acidic condensate - common when oil or gas appliances vent through old coal-era chimneys - we’ll recommend relining with DuraFlex stainless steel or HeatShield cerfractory flue sealant.

Chimney Waterproofing
Millbury’s heavy snowpack and ice-dam-prone roof pitches drive meltwater straight into chimney crowns and caps. We apply professional-grade, vapor-permeable waterproofing agents from Copperfield that allow the masonry to breathe while blocking liquid water entry. This is not the hardware-store sealant that traps moisture and accelerates damage. We treat the full chimney exterior above the roofline, with special attention to the crown-to-flue joint where most leaks originate. A proper waterproofing treatment in Millbury typically lasts 7-10 years if the crown and cap are sound.

Flashing Repair
Step flashing and counterflashing around your chimney are the most common leak points we find in Millbury’s older homes. Original installations were often lead or galvanized steel that has fatigued through decades of thermal cycling. We fabricate and install custom flashing using professional-grade materials, sealed with high-temperature compounds, and integrated properly with your roofing system. On the post-war Cape Cods in Millbury’s suburban edges, we frequently find DIY patch jobs that have trapped water against the sheathing; we remove these, inspect for rot, and install correct flashing that sheds water the way it was designed to.
For chimney cap and crown-specific work, we also offer Chimney Cap & Crown in Millbury as a dedicated service.

Common Chimney Repair Problems We See in Millbury Homes
- Crumbling clay flue tiles in century-old chimneys. Millbury’s original heating chimneys were built for coal and later adapted for oil or gas without proper relining. A Level-2 camera inspection almost always reveals cracked, shifted, or missing tiles that a standard sweep would miss entirely.
- Spalling brick from freeze-thaw damage above the roofline. The exposed portion of your chimney endures the worst of Worcester County’s weather. Soft, low-fired 19th-century brick simply cannot withstand decades of water saturation followed by hard freezes without protective maintenance.
- Deteriorated mortar joints allowing water into the chimney structure. Once mortar erodes to 1/4 inch depth or more, water enters the wall system, accelerates brick deterioration, and can migrate into your home’s framing. We catch this early with documented inspections.
- Failed chimney crowns with cracks running to the flue edge. Concrete crowns on Millbury’s older chimneys were often poured too thin or without proper reinforcement. Freeze-thaw opens cracks, meltwater enters, and the freeze-thaw cycle widens them until the crown requires complete reconstruction.
