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.

AfterFast, Reliable Chimney Liner & Rebuild Across Malden
Chimney liner replacement and partial rebuilds in Malden typically run $2,800-$6,500 depending on flue count and stack access, with most jobs scheduled within a week of your call. We dispatch crews to Malden from our Boston office daily, and we’ve worked on enough triple-deckers along Pleasant Street, Ferryway, and the Maplewood stretch to know the permitting rhythm the city expects. If your chimney serves multiple units or you’re seeing tile fragments in the cleanout, call (857) 392-4709 - a live person answers, and we’ll walk you through what a camera inspection will show before we book anything.
Why Hearthstone Chimney Co. Is Malden’s Preferred Chimney Liner & Rebuild Company
We’ve been answering calls with a live person for over 42 years, and that hasn’t changed. Malden homeowners know our trucks because we’ve been pulling up to triple-deckers here since the early 1980s, back when oil-to-gas conversions were just starting to overload clay flues with cooler exhaust.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your liner has three seasons left, we’ll say so. If it’s spalling and sending shards into the smoke chamber, we’ll show you the footage and explain exactly why.
Our Chimney Liner & Rebuild in Malden crews are background-checked, uniformed, and carry professional-grade materials from DuraFlex, HeatShield, and Copperfield on every truck. Most liner replacements and partial rebuilds finish in a single visit once scheduled. Our no-hassle upfront pricing means the number on the estimate is the number on the invoice - a square deal, no surprises on the bill.
The 90-Day Done Right Promise backs every job in writing. If it’s not right, we make it right. No paperwork to dig up, no arguing. That’s the Keystone Standard we’ve operated under since 1984.
Our Chimney Liner & Rebuild Services in Malden
Stainless Steel Liner Installation
Stainless steel liners are our most common install in Malden triple-deckers. The 316Ti alloy we use from DuraFlex handles the acidic condensation that forms when low-temp gas boilers vent into oversized coal-era flues. In a typical Ferryway three-family, we’ll drop a correctly sized liner from the crown to the appliance connection, insulate per NFPA 211, and seal the top with a new cap and proper flashing. The old flue was probably 8×12 inches for coal. Your gas boiler needs 5 inches round. We size it right, or the moisture never stops.
Flexible Liner Systems
Some Malden stacks have offsets or bends from century-old construction that rigid pipe can’t navigate. Flexible liners solve that. Our crews carry DuraFlex Pro and Olympia Chimney flex kits with the torque-rated connectors that pass Malden’s inspection requirements. Flexible installs cost roughly the same as rigid in straight flues but save significant labor when the chimney has a dogleg between floors - common in 1890s wood-frame conversions near Maplewood.
Liner Replacement
Full liner replacement becomes necessary when clay tiles are spalling, cracked, or missing sections - what we find in most Malden chimneys that haven’t been inspected since the last owner. The process: camera inspection first, photo report to all owners, permit application to Malden Building Department, then removal of debris and installation of the new system. We coordinate with every party who shares the stack. One owner can’t sign for three. We’ve learned the patience this requires, and we build that timeline into every Malden quote.
Partial Chimney Rebuild
When freeze-thaw damage has destroyed mortar joints and the outer wythe of brick is separating from the flue, a liner alone won’t save the structure. Partial rebuilds address the top courses, crown, and flashing - the areas that take the worst beating. In Malden, we see this most on chimneys that haven’t been repointed since the 1970s. Eastern Massachusetts averages 35-45 freeze-thaw cycles each winter. Porous brick absorbs that moisture, expands, contracts, and eventually the face of the brick pops off. We rebuild with matching brick where possible, pour a new concrete crown with proper drip edge, and flash to the roofline so water stays outside.

Trusted Brands We Service in Malden
We don’t use builder-grade substitutes. Our trucks stock DuraFlex stainless liners and flex kits, HeatShield cerfractory resurfacing compound for flue walls with minor degradation, and Copperfield chimney caps and flashing components. For Malden triple-deckers needing custom-fabricated solutions, we source through Famco. These are the brands that professional sweeps specify, and they carry the warranties that matter when you’re installing in a structure that needs to last another century. Because we keep common sizes in stock, most Malden jobs don’t wait on parts.
Common Chimney Liner & Rebuild Problems We See in Malden Homes
- Oversized gas flues destroying clay tiles. Malden’s triple-deckers were built with 8×12 or 10×10 flues for coal furnaces. Modern gas equipment runs cooler and wetter. The exhaust condenses on tile surfaces, soaks in, and the freeze-thaw cycle cracks them into spalling shards. We find this on nearly every unlined gas flue we inspect in Malden.
- Multi-party coordination stalling permits. One chimney stack, three flues, two or three separate owners. Malden’s housing DNA means no liner job starts until every party signs off. We’ve seen permits sit for six weeks while owners debate cost splits. We build this reality into our project timeline and help facilitate the conversation.
- Never-repointed mortar accelerating structural failure. Brick chimneys on Pleasant Street and the older Maplewood blocks often have mortar that’s turned to sand. Water penetrates, freezes, expands, and the wythe separates. A timely inspection and repointing job prevents the $8,000+ full rebuild that follows.
- Mixed fuels in shared stacks creating incompatible venting. One flue still on oil, one converted to gas, one abandoned. Each fuel type produces different exhaust temperatures and corrosiveness. The gas flue runs cool and wet. The oil flue runs hot and sooty. They share a wall. The thermal stress cracks tiles faster than any single-fuel chimney would experience.

FAQs - Chimney Liner & Rebuild in Malden
Every owner with a flue in that stack must agree to the scope and cost split before Malden Building Department will issue a permit. We inspect all flues, produce a single photo report, and provide separate line-item quotes per flue. Owners can proceed together or separately, though shared scaffolding and roof protection typically make coordinated work more economical. We’ve facilitated these conversations for decades. Call (857) 392-4709 and we’ll explain how we handle the coordination.
Annually, and in Malden’s triple-deckers we’d push for every burning season. Gas exhaust is cooler and wetter than oil or coal, and your oversized flue traps condensation against clay tiles that were never designed for it. The NFPA 211 standard says yearly inspection for all chimneys, and Malden’s housing stock makes that standard more relevant here than in newer construction. Call (857) 392-4709 to schedule - estimates are free.
Because the same moisture that destroys liners also destroys mortar. By the time clay tiles are spalling, the freeze-thaw damage has usually reached the brick joints and crown. Installing a liner in a structurally compromised stack is like putting a new engine in a rusted frame. We won’t do it without addressing the envelope. Our camera inspection shows you exactly where the line falls between liner-only and rebuild. Call (857) 392-4709 for a clear assessment.
Our Level-2 inspection includes full interior flue scanning with a remote camera, photos of every defect, measurements of flue dimensions and clearances, and a plain-English verdict on liner condition, structural integrity, and code compliance. You receive the photo report and a flat, itemized quote before any work is authorized. No surprises on the bill. The 90-Day Done Right Promise covers everything we do. Call (857) 392-4709 to book.
Some conditions can wait a season; others should not run again until repaired. A cracked liner with visible gaps and spalling tiles is a carbon monoxide and fire risk - we recommend shutting down the appliance until replacement. Minor tile degradation with intact structure can sometimes be monitored annually if the appliance is properly venting. We’ll tell you which category you’re in, with photos so you can see for yourself. No scare-selling. Call (857) 392-4709 and we’ll give you a straight answer.
