We’ve been driving to Randolph since before the Route 24 interchange was rebuilt, and we know the chimneys here. The town’s post-war build-out left thousands of Cape Cods, raised ranches, and split-levels with single-flue brick chimneys sized for oil-fired boilers, not the gas conversions and heat pumps that now vent through them. That mismatch between flue size and appliance output is the root cause of most liner failures we diagnose on the north side near the Blue Hills, down toward North Main Street, and through the Liberty Street corridor.

Why Hearthstone Chimney Co. Is Randolph’s Preferred Chimney Liner & Rebuild Company

Russell Haines built this company in 1984 on the idea that a chimney sweep should explain the problem like a craftsman and stand behind the fix like a professional. Forty-two years later, that still means photos you can see, a plain-English verdict, and the 90-Day Done Right Promise in writing - no paperwork, no arguing. Our dispatch is coordinated from our Boston office, but our crews live in the corridor and know Randolph’s housing stock cold.

We’ve earned our reputation in Randolph one appointment at a time. Homeowners here are practical people who’ve owned their houses for decades and intend to stay. They remember the contractor who disappeared after the deposit, or the sweep who declared a liner “fine” without ever running a camera. We answer every call with a live person, 24/7, because that’s the kind of company that plans to be in town thirty years from now. Our technicians are background-checked, uniformed, and trained to document everything - cracked clay tiles, joint separation, clearance measurements, crown condition - before suggesting any work.

The difference shows up in callbacks, or rather in the lack of them. When we install an Olympia Chimney stainless liner sized precisely to the appliance, or apply HeatShield resurfacing to a sound flue with isolated joint gaps, the fix holds. That’s the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.

Our Chimney Liner & Rebuild Services in Randolph

Stainless Steel Liner Installation

A stainless steel liner is the right choice when Randolph’s original clay tiles are too far gone for repair - spalled, cracked through the body, or separated at the joints beyond what resurfacing can seal. We use Olympia Chimney and DuraFlex materials sized precisely to your appliance’s BTU output and venting requirements, not the oversized flue left behind from an oil boiler. In a 1960s Cape Cod near North Main Street, that often means dropping a 5-inch or 6-inch flexible stainless liner down a flue that was built for 8-inch or larger clay tile. The smaller diameter runs hot enough to maintain draft and evacuate combustion gases completely, which solves the chronic condensation that was eating the old clay from the inside out.

Most stainless installations in Randolph run $2,200-$3,800 and are completed in one day. We pull the permit, coordinate the inspection, and leave the work area cleaner than we found it.

Flexible Liner Solutions

Not every chimney in Randolph is straight. The offset flues in some split-levels and raised ranches, particularly in the neighborhoods off Liberty Street and toward the Holbrook line, need a liner that can navigate bends without losing integrity. Flexible stainless liners from DuraFlex handle those transitions while maintaining the same corrosion resistance and proper sizing as rigid pipe. We measure the offset with a camera first, then specify the right flexibility grade and insulation wrap for your specific flue path. Done right - and we stand behind it.

Liner Replacement

Full liner replacement becomes necessary when the clay tile system has reached end of life, which in Randolph’s 50-70-year-old chimneys is increasingly the case. But “replacement” is also the industry’s most abused upsell. We’ve been called to homes where a previous sweep quoted $4,000 for stainless replacement based on a flashlight glance up the flue, only to find on camera that HeatShield resurfacing would have addressed isolated joint gaps for a fraction of the cost. Our rule: no replacement is recommended without Level-2 camera evidence you can see for yourself, and a plain-English explanation of why repair won’t suffice.

When replacement is genuinely needed, we remove the deteriorated clay, inspect the surrounding masonry for soundness, and install the new system with proper insulation and termination. Typical range in Randolph: $2,800-$4,200.

Partial Chimney Rebuild

Sometimes the liner isn’t the only problem. Randolph’s repeated freeze-thaw cycles, especially on the north and west faces of chimneys exposed to prevailing winds off the Blue Hills, can deteriorate the masonry above the roofline while the lower flue remains sound. A partial rebuild addresses the crown, the top few courses of brick, and the flashing interface without tearing down a structurally sound stack below. We match existing brick and mortar color where possible, install a proper concrete crown with positive drainage, and ensure the new cap and liner termination work as a system. Most partial rebuilds in Randolph fall between $1,800-$3,200.

Trusted Brands We Service in Randolph

We don’t use builder-grade substitutes. For liner installations and rebuilds in Randolph, we specify HeatShield for ceramic resurfacing of sound flues with isolated joint failure, Gelco for caps and termination components that need to withstand Norfolk County’s wind-driven rain, and Olympia Chimney for stainless steel liner systems that will outlast the next roof. These are the same brands specified by factory-built fireplace manufacturers and referenced in NFPA 211. We stock common diameters and fittings locally, so most Randolph jobs don’t wait on parts.

Common Chimney Liner & Rebuild Problems We See in Randolph Homes

• Oversized flue running too cool after fuel conversion. The original clay liner in your 1965 raised ranch was sized for an oil boiler firing at 150,000 BTU. Your new gas system runs at 80,000. That oversized flue never gets hot enough to establish proper draft, so combustion gases condense on the tile surfaces, accelerating joint separation and spalling. We measure the flue and the appliance output, then specify a liner that matches.
• Low-profile chimney losing clearance after re-roofing. Many of Randolph’s 1960s Cape Cods have chimneys that barely satisfied the 2-foot-in-10 rule when built. Add architectural shingles that are 50% thicker than the original three-tabs, or a ridge vent that sits higher, and the effective clearance drops below code. The result is persistent downdraft and smoke rollback that technicians in taller-chimney towns like Milton rarely encounter. We measure actual clearance and can extend the stack or install a proper draft-inducing cap.
• Clay tile spalling from freeze-thaw cycling. Randolph’s inland location means more temperature swing than coastal Massachusetts - above freezing during a January thaw, then single digits the following night. Water penetrates cracked tiles, freezes, and pops off surface layers. By the time you see debris in the firebox or hear rattling in the flue, the damage is usually extensive enough to require camera confirmation.
• Unnecessary full-liner quotes based on no evidence. This is the one that burns homeowners. A sweep declares the liner “shot” without running a camera, or shows you a generic photo from some other chimney. We document your actual flue, show you the footage on screen, and explain exactly what we’re seeing. Sometimes it’s a full replacement. Sometimes it’s HeatShield resurfacing of three joint gaps. You get the truth either way.
