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.

AfterOlympia Chimney Chimney Cleaning & Sweep in Cambridge: What to Know First
We provide independent Olympia Chimney chimney cleaning and sweep services throughout Cambridge, with most Level 1 and Level 2 inspections and standard sweeps completed in a single visit. Our pricing is agreed upfront, and we do not recommend work without camera evidence you can see for yourself. If your Olympia Chimney liner, cap, or venting system needs attention, call (857) 392-4709 - a live person answers, 24 hours a day.
This page is for Cambridge homeowners who installed an Olympia Chimney product during a renovation or fireplace upgrade, or who bought a home with one already in place and need honest service without the runaround. We are not affiliated with or authorized by Olympia Chimney. We are an independent service provider who has worked on their systems across Cambridge for years, including the tight flue configurations common in the triple-deckers near Inman Square and the older conversions along Mass Ave.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney ProFlex liner series: The ProFlex’s corrugated stainless construction traps creosote in the valleys between ridges, especially when homeowners burn unseasoned hardwood or run the fireplace as a primary heat source through Cambridge’s damp shoulder seasons. We remove buildup with rotary polypropylene brushes sized to the corrugation profile, then verify clearance with a video scan. If the liner has pulled away from the top collar - common after thermal cycling in New England winters - we reseat with an Olympia-compatible top plate or, if the original is cracked, a Gelco termination fitting that mates cleanly.
- Olympia Chimney smooth-wall rigid liners: These carry draft better but develop pinhole leaks at the seam welds after 15-20 years, particularly where condensation pools in low spots on flat roofs in Cambridgeport. During a Level 2 sweep, we pressurize-test suspect sections and document with photos. When repairable, we apply HeatShield Cerfractory Foam to seal from the inside; when the damage is extensive, we pull a DuraFlex replacement of matching diameter.
- Olympia Chimney Gelco cap and shroud assemblies: The mesh on early Gelco caps (pre-2015) rusts through at the welds faster than the stainless frame, letting squirrels and starlings nest in the flue. We replace with current-spec Gelco mesh or upgrade to a Copperfield cap with 5/8-inch spark arrestor spacing, which meets Cambridge fire code without the airflow restriction that chokes marginal drafts.
- Olympia Chimney wind-directional chimney pots: The rotating collar seizes with creosote glaze after seasons of inactivity, common in summer cottages along the Charles that convert to year-round use. We disassemble, soak the bearing in degreaser, and reassemble with high-temp anti-seize. If the pot body is cracked from freeze-thaw, we source a replacement through Famco rather than gamble on generic pots that do not match the throat diameter.
- Olympia Chimney fireplace face and surround panels: The refractory panels in some factory-built fireplaces develop hairline cracks from rapid heating when homeowners crank the thermostat after a Cambridge cold snap. These are not swept away - they are replaced. We measure with a template, order the correct Olympia panel or a HeatShield-compatible equivalent, and install to the manufacturer’s clearance spec so the warranty on the firebox remains intact.
Our Olympia Chimney Chimney Cleaning & Sweep Process
- 1
Call and schedule. A live person answers, day or night. We ask the model name or series if you know it, the fuel type, and when you last had service. We quote a range upfront - no surprises on the bill.
- 2
Arrival and protection. Our technician arrives in uniform, lays drop cloths from the door to the hearth, and runs a HEPA-filtered vacuum before touching a tool. Background-checked, every one of them.
- 3
Level 1 or Level 2 inspection. We scope the flue with a camera you can watch in real time. For Olympia Chimney liners, we note the series, condition of the collar and termination, and any creosote glazing pattern that indicates a combustion or airflow problem.
- 4
The sweep and any repair. We match brush type to liner construction - poly for corrugated stainless, flat wire for smooth-wall, whip for heavy glazed creosote. If we find a separable joint or damaged component, we explain the fix, show you the photo, and proceed only with your go-ahead.
- 5
Post-service test and documentation. We run a draft test, provide a written condition report with photos, and register your sweep with our handwritten service log. The 90-Day Done Right Promise applies in writing, no arguing.
- 6
Cleanup and close. We vacuum again, remove every cloth, and leave the work area cleaner than we found it. Payment is handled - the number on the estimate is the number on the invoice.

Why Cambridge Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We have been in business since 1984 - over 42 years - and we plan to be here when your Olympia Chimney system needs its next sweep. That changes how we work. The 90-Day Done Right Promise is not a slogan; it is in writing, and if something is not right, we make it right with no paperwork and no arguing. Our technicians are background-checked, uniformed, and trained on Olympia Chimney’s specific clearances and coupling methods, not generic “chimney guy” improvisation.
We also stock and work with DuraFlex, HeatShield, Gelco, and Famco products, so when an Olympia part is back-ordered or discontinued, we have a quality path forward that does not leave you waiting through another burning season. Russell Haines keeps that handwritten service log because he believes the work should be remembered. If it needs doing, we will tell you. If it does not, we will tell you that too.
FAQs
No. Routine chimney cleaning and inspection by a qualified professional does not void your Olympia Chimney warranty, provided the work does not alter the system beyond factory specifications. We document our methods and materials so there is a clear record if a warranty question ever arises. Call (857) 392-4709 if you need a copy of our service documentation for your files.
Once per year for wood-burning systems, per NFPA 211. In Cambridge’s humid summers, we sometimes find accelerated corrosion in gas-venting Olympia Chimney liners that have not been inspected in two or more years. Annual inspection catches this before it becomes a replacement. Call (857) 392-4709 to schedule - estimates are free.
We source OEM when it is available and cost-effective. When Olympia Chimney has discontinued a part or the lead time extends past burning season, we use professional-grade equivalents from Gelco, Famco, or DuraFlex that meet or exceed the original spec. We explain the trade-off and show you both options before ordering. Call (857) 392-4709 for specifics on your model.
The camera tells the story. Spot damage - a cracked collar, a single separable joint, localized creosote corrosion - we repair. Multiple fractures, widespread pitting, or any gap that compromises the liner’s ability to contain combustion gases means replacement. We show you the footage, explain the threshold, and let you decide. No scare tactics. Call (857) 392-4709 for a Level 2 inspection.
Glazed creosote builds in layers. Eventually it restricts draft, causing smoke to back up into the room or carbon monoxide to spill. In the worst case, it ignites. Cambridge Fire Department responds to chimney fires every winter, many in systems that had not been inspected in years. The risk is real, but so is the cost of unnecessary work - which is why we inspect first and recommend only what the evidence supports. Call (857) 392-4709 for an honest assessment.
