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 Somerville
A chimney liner or partial rebuild in Somerville typically runs $2,800-$7,500 depending on flue count and access, with most jobs scheduled within a week and completed in a single visit. Our crews know the borough’s tight lots and century-old brick chimneys well - we’ve been working Somerville’s late-Victorian housing stock for over 42 years. Call (908) 589-8342 to speak with a live person and book your free estimate.
Somerville’s borough core, the streets radiating from Main Street and the Somerset County courthouse, presents a chimney challenge unlike anywhere else in Somerset County. The density of 1880-1930 brick homes with original multi-flue masonry chimneys means shared chases, adjacent flues, and cross-contamination risks that a one-size liner job won’t solve. We dispatch from our New York City coordination office, but our trucks roll into Somerville regularly - and our technicians arrive knowing what to look for on these old brick stacks.

Our Chimney Liner & Rebuild Services in Somerville
Stainless Steel Liner Installation
Stainless steel liners are our go-to for Somerville’s active heating flues, especially where a gas conversion left an old clay tile system cracked and porous. We size each liner to the appliance - boiler, furnace, or water heater - and use professional-grade DuraFlex or Olympia Chimney products, never builder-grade substitutes. On the tight rooflines near Division Street and Grove Street, our crews have learned the access angles that let us drop a liner cleanly without disturbing neighboring flashing or walking a brittle crown.
Flexible Liner Systems
Flexible liners solve the offset flues we find constantly in Somerville’s Victorian-era chimneys, where original construction wasn’t plumb and decades of settling have created bends a rigid liner won’t navigate. A flexible DuraFlex liner conforms to these irregular channels while maintaining proper draft. We recommend flexible systems for many of the borough’s older homes, particularly where a Level-2 inspection reveals hidden offsets between the fireplace throat and the chimney top.
Liner Replacement
Liner replacement is the core of what we do in Somerville. The borough’s 1880-1930 chimneys were built for coal or wood, then retrofitted for gas or oil - often incompletely. We regularly find active flues with deteriorated clay tile, and abandoned flues left bare to vent moisture into the surrounding brick. Our liner replacement service pulls the old system, inspects the chase with a camera, and installs a new stainless or flexible liner sized to current code. Every replacement includes a new cap and proper termination to stop water entry.
Partial Chimney Rebuild
Partial rebuilds address what Somerville’s frost-pocket climate does to century-old masonry. The Raritan Valley’s cold-air drainage creates freeze-thaw cycling harder than neighboring Readington or Bedminster experience, cracking clay flue tile and spalling mortar joints until the stack leaks draft and lets creosote glaze build where a brush can’t reach. A partial rebuild replaces the damaged courses, rebuilds the crown, and repoints mortar joints - restoring structural integrity without the cost of a full teardown. We match existing brick and mortar color where possible, because a rebuild should look like it belongs on the house.

Trusted Brands We Service in Somerville
We work exclusively with professional-grade materials from industry-trusted brands: DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. No builder-grade substitutes. For Somerville homeowners, this means we stock the liners, caps, and crown materials your chimney needs - no waiting on special orders that stretch a one-day job into three.

A square deal: no surprises on the bill.
Common Chimney Liner & Rebuild Problems We See in Somerville Homes
- Shared chases with orphaned flues. On a late-Victorian brick home off Main Street near the Somerset County courthouse, our crew found a chase holding two flues - an active gas appliance flue that had been relined and an orphaned, uncapped fireplace flue venting moist ambient air straight into the surrounding masonry. We dropped a HeatShield liner in the abandoned flue, sealed it with a new chimney cap, and rebuilt the spalled crown and mortar joints that the frost-pocket cycling had opened up.
- Frost-pocket freeze-thaw destruction. Somerville sits in the Raritan River valley, where cold-air drainage creates frost-pocket conditions that intensify freeze-thaw cycling on exposed masonry. This accelerates mortar joint spalling and clay flue tile cracking beyond what neighboring upland towns experience, making annual inspection especially critical for the borough’s older chimney stock.
- Tight roof access damaging crowns before work begins. The postage-stamp lots radiating off Main Street leave little room for crew movement. A step short, flashing disturbed, and a chimney crown cracked by foot traffic - we’ve seen it. Our technicians carry protective mats and work from ladder brackets where possible to avoid walking brittle crowns.
- Cross-contamination in attached housing. Somerville’s dense Victorian housing includes attached properties and duplexes where neighboring flues share a chase. A gas-appliance flue relined at conversion may be safe, while the adjacent abandoned flue vents moisture and combustion byproducts into the same masonry stack - quietly rotting it from the inside and creating draft hazards neither homeowner detects alone.

FAQs - Chimney Liner & Rebuild in Somerville
Yes, we can install a liner in your flue alone, but we must inspect the entire shared chase first. In Somerville’s dense Victorian housing, we regularly find that an active flue and an abandoned flue share the same masonry - and the unlined, uncapped flue is venting moisture into the stack, damaging both sides. Our camera inspection documents the full chase condition before we quote. Call (908) 589-8342 to schedule - estimates are free.
You’re seeing frost-pocket freeze-thaw damage, not fire damage. Somerville’s position in the Raritan River valley traps cold air, accelerating the freeze-thaw cycle that pops mortar joints and spalls brick faces. An unlined or deteriorated flue lets combustion moisture from your gas appliance into the masonry, compounding the problem. A liner stops the moisture intrusion; repointing and crown repair address the existing damage. Call (908) 589-8342 for an inspection and exact quote.
A partial rebuild replaces damaged sections - typically the top few courses, the crown, and any spalled brick - while preserving sound lower masonry. A full rebuild tears down to the roofline or below and reconstructs the entire stack. For Somerville’s 1880-1930 chimneys, we often recommend partial rebuilds when the lower brick is sound but the crown and upper courses have succumbed to frost-pocket cycling. The camera inspection tells us which applies to your chimney. Call (908) 589-8342 - we’ll show you the photos and explain your options.
We need interior access to inspect the appliance connection, the firebox or thimble, and to run our camera up the full flue length. The liner itself is dropped from the roof, but the connection at the bottom and the final draft test require us to work both ends. In Somerville’s tight lot configurations, we coordinate access to minimize disruption - most jobs are completed in a single visit. Call (908) 589-8342 to schedule.
Level 1 is a visual check - appropriate if your chimney has been regularly maintained and nothing has changed. Level 2, with camera inspection of the full flue interior, is required for any liner or rebuild work, after a chimney fire, or when you’re buying or selling a home. Level 3 involves removing building materials to access hidden areas - we only recommend this when Level 2 reveals a problem we can’t fully diagnose. For Somerville’s century-old chimneys, we start with Level 2. Call (908) 589-8342 to book yours - estimates are free.
