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.

Why Level Two Chimney Cambridge Is Lexington’s Preferred Fireplace Services Company
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, every one with a written price before work started and a documented photo record when it was done. Lexington homeowners make up a growing share of that count, particularly in the postwar Cape belt between Route 2 and the Battle Green and the modernist clusters off Concord Avenue.
Our reviews from Lexington customers consistently cite the same thing: the camera footage. Where other companies charge for a flashlight look and call it an inspection, Clause 4 of the Haven Standard requires a photo record on every job - and we’ve done that since 2009, years before insurers or the NFPA asked for it. You get the images, the written scope, and the written warranty before anyone picks up a tool.
Dispatch and scheduling are coordinated from our Boston office, but crews serve Lexington locally. Background-checked, uniformed technicians with license numbers displayed on every page. A named tech assigned to your job, with a text when they’re on the way. Live phone support, 24 hours a day, 7 days a week - not a voicemail, not a web form.
The 365-Day Done Right Promise applies to every Lexington job: if it’s not done right, we make it right. And our Free Second Opinion on any written estimate means you can bring us a competitor’s quote and we’ll tell you exactly what we see.
Our Fireplace Services in Lexington
Wood Burning Fireplace Service
Lexington’s inland position gives it colder average lows and heavier snowpack than coastal towns at similar latitude, driving a wood-burning season from October through late April that accelerates creosote accumulation. In pre-1900 chimneys near the Battle Green, we regularly see freeze-thaw spalling of lime-mortar joints and clay-tile flue liners that turns a routine cleaning visit into a Chimney Repair in Lexington call. On postwar Capes along Woburn Street and Bedford Street, galvanized caps and flashing have often rusted through after 60+ winters, letting water track into the smoke chamber. We document everything with camera footage, quote the repair in writing, and perform only the work you approve.
Gas Fireplace Service
Gas fireplaces in Lexington’s 1950s-1970s colonials and Capes often have original valves, thermocouples, and log sets that have never been serviced. We test gas pressure, inspect the burner orifice for spider webs and debris, check the thermopile output in millivolts, and verify that the glass panel seals properly. In newer homes near Lexington Center, direct-vent inserts sometimes suffer from failed blower motors or cracked refractory panels. Every gas service includes a written combustion analysis and a photo record of the firebox interior, the gas valve tag, and the vent termination.
Fireplace Insert Installation
Inserts are popular in Lexington’s drafty postwar Capes where the original fireplace was built for atmosphere, not heat output. We size the insert to your existing firebox, verify the flue liner compatibility (often requiring a new stainless or DuraFlex liner), and handle the hearth extension and surround to code. In Six Moon Hill and Five Fields homes with shallow modernist fireboxes, inserts sometimes require custom surround panels or a modified smoke chamber to achieve proper draft. We source materials through Haven’s buying network to keep customer prices honest, and we never install an insert without a camera inspection of the flue first.
Damper Repair and Replacement
A stuck or rusted damper wastes heated air and can prevent proper draft. In Lexington’s coastal-exposed chimneys, we see damper frames corroded through, throat dampers frozen solid with creosote, and top-sealing dampers with failed springs. We repair what can be repaired and replace what can’t, always with a written price before work starts. In modernist homes with marginal chimney height, a top-sealing damper often improves draft performance more than a throat repair.
Firebox Repair
The firebox takes the direct heat, and in Lexington it fails in two distinct patterns. In 1700s colonials near the Battle Green, we repoint firebrick with high-temperature refractory mortar and rebuild firebox walls where the original lime mortar has turned to dust. In 1950s Capes, we see cracked refractory panels, rusted-out metal fireboxes, and heat-damaged throat transitions. We document the damage with photos, explain what can wait and what can’t, and give you a written scope and warranty.
Fireplace Conversion
Converting a wood-burning fireplace to gas - or vice versa - requires a Level 2 inspection, a written plan, and often a new liner. In Lexington’s historic district, we coordinate with the Historic District Commission when exterior alterations are involved. In modernist homes, conversions sometimes require creative venting solutions due to minimal chimney height. We handle the permitting, the inspection, and the documentation.
BeforeAfterTrusted Brands We Service in Lexington
We stock parts and materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - procured through Haven’s buying network specifically to keep customer prices honest. For Lexington customers, this means faster turnaround on repairs that would otherwise require special orders. A rusted cap on a Woburn Street Cape can be swapped with a stainless Famco unit same-visit. A failed clay-tile liner in a Battle Green colonial can be resurfaced with HeatShield cerfractory foam in one day, not two. We don’t markup parts and hide it in labor; the written price lists every component separately.
Common Fireplace Services Problems We See in Lexington Homes
- Chimney crown and flashing corrosion on low-slope modernist rooflines. In Six Moon Hill and Five Fields, runoff and snowpack sit against the masonry edge longer than on a pitched colonial roof, accelerating cap and crown failure. We inspect these with the camera before recommending replacement.
- Under-drafted fireboxes in TAC-designed homes. Chimneys that barely clear the 2-foot-above-10-foot rule, combined with shallow 1950s fireboxes, push creosote straight past first-degree into glazed buildup. We measure draft pressure and recommend solutions that actually fix the geometry, not just sweep the symptom.
- Freeze-thaw spalling in pre-1900 Battle Green chimneys. Repeated freeze-thaw cycles attack lime-mortar joints, causing brick faces to pop off and clay tiles to crack. We flag this during routine cleaning and quote repointing or relining before water intrusion worsens it.
- Galvanized cap and flashing failure on postwar Capes. The 1950s-1970s building boom in Lexington used galvanized steel that rusts through in 40-60 years. We replace with stainless components sized for the specific flue and roof pitch.

FAQs - Fireplace Services in Lexington
Once per year, per NFPA 211, regardless of burn frequency. Lexington’s long heating season and freeze-thaw cycles mean moisture damage progresses whether you light fires or not; an unused flue is often a more deteriorated flue because condensation sits without drying heat. Call (857) 309-1908 to schedule - estimates are free.
The TAC-designed homes in Six Moon Hill and Five Fields have flat or shed-style rooflines that leave chimneys barely clearing the 2-foot-above-10-foot rule, so draft is chronically marginal; combined with the shallow fireboxes fashionable in 1950s modernist design, smoke lingers and creosote glazes faster than in a conventional colonial with proper height and depth. We measure actual draft pressure and can often improve performance with a top-sealing damper, a smoke chamber modification, or a properly sized liner. Call (857) 309-1908 for a camera inspection and written solution.
Galvanized caps and flashing rust through first, typically in 40-60 years on Lexington’s postwar stock; on modernist low-slope roofs, the crown itself cracks from pooled water and freeze-thaw. Stainless components last indefinitely but must be properly sized for marginal-clearance chimneys. We inspect with the camera, show you the corrosion, and quote replacement with the right material for your exposure. Call (857) 309-1908 for a free estimate.
First-degree creosote is flaky, sooty, and brushes off easily - common with dry hardwood and hot fires. Third-degree glaze is a hard, shiny, tar-like layer baked onto the flue wall, often requiring rotary chains or chemical treatment to remove; we see it routinely in Six Moon Hill’s under-drafted fireboxes where cool, slow burns predominate. The camera shows the difference clearly, and we classify what we find in your written report. Call (857) 309-1908 to see what your flue actually contains.
Cap first, always. A rusted cap lets water into the flue, and water destroys clay tiles from the top down through freeze-thaw. Once the cap is replaced with stainless, we camera the liner to assess tile condition; if tiles are cracked or missing, we quote HeatShield resurfacing or a DuraFlex stainless liner before recommending any fireplace use. Doing it in reverse - lining first, cap second - wastes money when water continues destroying the new work. We write the sequence and price before starting. Call (857) 309-1908.
