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.

Call (857) 392-4709 - a live person answers, every hour of every day.
Malden’s chimneys are not like the ones in the suburbs. Most were built for coal, converted to oil, then converted again to gas. The flues are oversized. The brick is porous. And in a triple-decker on Pleasant Street or a two-family off Salem Street, your chimney stack might serve three separate households on three different heating fuels. That changes everything about how you diagnose, how you quote, and how you get the work done. Our Chimney Repair team knows the difference.
Why Hearthstone Chimney Co. Is Malden’s Preferred Chimney Repair Company
We’ve been answering the phone with a live person for over 42 years. Not a voicemail. Not a callback queue. When a Malden homeowner calls at 6 PM on a Saturday because water is dripping through the ceiling near the chimney breast, someone picks up.
Our technicians are background-checked and uniformed, and most repairs are completed in a single visit. We use no-hassle upfront pricing - the number on the estimate is the number on the invoice. No surprises on the bill.
Every inspection ends with photos you can see and a plain-English verdict. We document like engineers and explain like craftsmen. And every job is backed by our 90-Day Done Right Promise in writing: if it’s not right, we make it right, no paperwork and no arguing.
We’re familiar with Malden’s permit process at City Hall, the specific challenges of triple-decker coordination, and the way winter hits these older brick stacks harder than it does new construction. That local fluency saves time and prevents callbacks.
Our Chimney Repair Services in Malden
Mortar Repointing
In Malden’s 1890-1930 housing stock, original mortar often hasn’t been touched in 40 or 50 years. Eastern Massachusetts averages 35-45 freeze-thaw cycles each winter, and porous brick on a triple-decker near Fellsmere Pond or along Main Street absorbs moisture that expands and shatters mortar joints from the inside out. Repointing - grinding out failed joints to proper depth and packing fresh, matched mortar - restores structural integrity and stops water infiltration before it requires a full rebuild. A typical repointing job on a Malden triple-decker chimney runs $1,200-$2,800.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is epidemic in Malden. Cool, oversized flues running modern gas exhaust condense moisture against clay tiles. That moisture migrates outward through the brick, and winter freeze-thaw cycling blows the faces off. We’ve replaced spalled courses on chimneys from Maplewood to Edgeworth, always matching existing brick where possible and addressing the moisture source so it doesn’t repeat. Single-area spalling repair typically costs $450-$950; extensive face replacement climbs toward $1,800.
Chimney Waterproofing
Malden brick is thirsty. Many of these chimneys were never sealed, and decades of exposure have opened capillary networks that drink up fall rain and hold it through winter. Our waterproofing treatment - a vapor-permeable silane/siloxane application from professional-grade suppliers - lets the brick breathe while blocking liquid water. It’s not a cosmetic coat. It’s a functional barrier that extends repointing intervals by years. For a standard Malden triple-decker stack, waterproofing runs $650-$1,100 and takes a single afternoon. We often pair it with crown repair, since a cracked crown is the fastest way to undo good waterproofing.
Flashing Repair
Step flashing and counterflashing where the chimney meets the roof are common failure points in Malden’s older housing. Original flashing was often lead or galvanized steel that has fatigued through decades of thermal cycling. We fabricate and install custom flashing using Copperfield components, sealed with professional-grade membranes. A straightforward flashing repair on a Malden two-family runs $550-$1,200; if the surrounding decking has rotted, costs rise accordingly, and we’ll show you the photos before you decide.
Chimney Rebuilding
Sometimes the damage has gone too far for spot repair. We’ve rebuilt chimney stacks from the roofline up on properties near Bell Rock Memorial Park and along Eastern Avenue, always using brick matched for color and hardness, with proper crowns and flue liners installed to modern code. A partial rebuild in Malden typically runs $2,500-$5,500; full rebuilds on taller triple-decker stacks can reach $8,000-$12,000. We never recommend rebuild without camera evidence you can see for yourself, and we’ll tell you plainly when work can safely wait a season.
Tuckpointing
Tuckpointing is the cosmetic cousin to repointing - matching mortar color to create the illusion of fine, uniform joints. In Malden’s historic districts and for homeowners who want the stack to look as sound as it is, we offer tuckpointing as a finish layer after structural repointing is complete. It adds $400-$800 to a repointing job but transforms the appearance of a weathered triple-decker chimney.

Trusted Brands We Service in Malden
We work exclusively with professional-grade materials - no builder-grade substitutes. For Malden’s demanding conditions, we specify DuraFlex stainless liners sized for low-temperature gas exhaust, HeatShield cerfractory resurfacing for compromised flue tiles, and Copperfield flashing and custom-fabricated components. These are the brands that other sweeps call for when their first attempt fails. We stock common sizes locally, so most Malden jobs don’t wait on shipping.
Common Chimney Repair Problems We See in Malden Homes
- Oversized flues condensing moisture. Century-old flues designed for coal furnaces now run cool gas exhaust. The moisture traps against clay tiles and accelerates spalling and liner breakdown far faster than in a properly sized single-family chimney.
- Freeze-thaw destruction of porous brick. Malden’s older brick was never meant to absorb and release water 35-45 times per winter. By March, we’re documenting new spalling and joint failure that wasn’t visible in October.
- Multi-party repair paralysis. In a triple-decker, three flues on three different fuels serve three separate owners. One landlord’s urgency is another’s “next year” problem, and the shared stack keeps deteriorating while everyone negotiates cost-sharing.
- Crown and flashing failure turning minor problems into structural ones. Water enters through a cracked crown or lifted flashing, saturates the masonry, and turns a $600 repointing job into a $4,000 rebuild in two or three winters of neglect.

FAQs - Chimney Repair in Malden
Every 12 months, without exception. The National Fire Protection Association recommends annual Level 2 inspection for all masonry chimneys, and Malden’s combination of oversized flues, multi-fuel conversions, and aggressive freeze-thaw cycling makes that minimum, not maximum. We schedule many of our triple-decker inspections for late March or early April, right after the freeze-thaw season, when damage is most visible. Call (857) 392-4709 to book - estimates are free.
Yes, with conditions. We can reline or repair a single flue within a shared stack without disturbing the others, provided the chimney structure itself is sound and we have access. However, if the crown, flashing, or exterior masonry requires work, that benefits all three units and the cost-sharing conversation becomes necessary. We’ll document exactly what is isolated to your flue versus shared, so you have clear numbers for that conversation. We’ve done this dozens of times on Malden triple-deckers.
Repointing is structural - removing failed mortar and packing new mortar to restore strength and water resistance. Tuckpointing is cosmetic - matching mortar color to create fine, uniform joint lines after the structural work is done. Your Malden chimney almost certainly needs repointing if it hasn’t been done in 30+ years. Tuckpointing is optional, a finish layer for appearance. We assess joint depth and integrity during inspection and tell you which applies.
First-degree creosote is flaky, sooty, and brushes off easily - common with dry, seasoned wood and hot fires. Third-degree (glazed) creosote is hard, shiny, tar-like, and requires chemical treatment or mechanical removal; it’s the fuel of chimney fires. You cannot safely distinguish them from the firebox. Our Level 2 camera inspection shows the flue surface in detail, and we’ll show you the footage. If glazed creosote is present, we remove it with professional-grade equipment - no shortcuts that leave residue behind.
Waterproofing applies a vapor-permeable silane/siloxane barrier that blocks liquid water while letting trapped moisture escape. For Malden’s porous, unsealed brick, it significantly slows freeze-thaw damage and extends repointing intervals. It can wait if your mortar joints are sound, your crown is intact, and you’re not seeing interior water staining. It cannot wait if spalling is active, joints are crumbling, or you’ve already had water infiltration. We’ll show you the photos and give you a straight answer on timing.
