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.

How Olympia Chimney Products Fail - and How We Fix Them
- Olympia 3000 Series wood-burning fireplaces: The refractory panels in these units crack diagonally across the firebox floor after repeated thermal cycling - a pattern we see often in Chelmsford because owners burn green or partially seasoned hardwood from local cordwood suppliers. We replace with Olympia-spec refractory cement board or factory-matched panels, never generic firebrick that changes the unit’s heat profile.
- Olympia direct-vent gas inserts (DV-32 and DV-42 lines): The pilot assembly on these collects condensation in Chelmsford’s freeze-thaw cycles, especially in homes near the Merrimack River where basement humidity runs higher. The symptom is a pilot that lights but won’t hold - homeowners replace thermocouples twice before realizing the pilot hood itself is corroded. We clean or replace the full pilot assembly and verify millivolt output at the valve.
- Olympia chimney-top dampers (OTD series):strong> The stainless cable frays where it passes through the chimney cap guide tube, usually at the 7- to 9-year mark. In Chelmsford’s older colonials near Heart Pond, the narrow, offset flues accelerate wear by forcing the cable through a sharper bend. We replace with OEM cable when available, or upgrade to a DuraFlex-compatible top-sealing damper if the frame is still sound.
- Olympia fireplace inserts with blower kits: The thermodisc fails open, so the blower never kicks on and the insert overheats the surrounding masonry. Homeowners smell hot drywall before they realize the fan isn’t running. We test amperage draw, replace the thermodisc and limit switch as a pair, and verify airflow across the heat exchanger.
- Olympia zero-clearance fireboxes in converted oil-to-gas homes: The original firebox was sized for wood or oil, and the gas log set someone dropped in creates localized overheating at the rear wall. We see this in West Chelmsford splits from the 1970s. The fix is a properly listed gas insert with an approved surround kit, or firebox rebuild with HeatShield cerfractory foam if the steel wrapper is still structurally sound.
Our Olympia Chimney Fireplace Services Process
- 1
Call and schedule: A live person answers at (978) 991-9492, 24 hours a day. We ask the model number if you have it, the symptoms, and whether the unit is gas or wood-burning.
- 2
Level-2 camera inspection: Our technician arrives in uniform, background-checked, with a chimney camera and combustion analyzer. We photograph the firebox, flue, and any components we suspect - you see the images on a tablet while we explain what we’re looking at.
- 3
Plain-English verdict and upfront price: We tell you what’s wrong, what caused it, and what it costs to fix. If an OEM Olympia part is back-ordered, we explain the aftermarket alternative and any trade-off in warranty coverage.
- 4
Repair with documentation: We complete most jobs in one visit. For gas units, we test manifold pressure and CO levels in the flue. For wood units, we verify draft and check for creosote buildup that could affect the new components.
- 5
Written guarantee: Every repair is covered by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back.
- 6
Cleanup and records: We leave the work area as we found it, and you keep the photos, the report, and the guarantee for your files.

Why Chelmsford Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We’ve been answering the phone with a live person for over 42 years, and we plan to be in Chelmsford in thirty more. That changes how you treat a customer.
Russell Haines and our technicians know Olympia Chimney products from hands-on work across hundreds of Massachusetts homes, including the older colonials near Heart Pond with their narrow, offset flues that test every sweep’s patience. When an Olympia part is discontinued or back-ordered, we draw on our experience with DuraFlex, HeatShield, and Gelco systems to find a solution that restores safe operation without compromising the unit’s listing.
Every job comes with photos you can see, a plain-English verdict, and our 90-Day Done Right Promise - in writing, no arguing. Background-checked, uniformed technicians. Most jobs completed in a single visit. A square deal: no surprises on the bill.
If the flue isn’t right, the fire isn’t safe - it’s that simple.
FAQs
No - as an independent Olympia Chimney service provider, we follow manufacturer installation and repair guidelines, and we use OEM or equivalent-listed parts. The warranty covers defects in materials and workmanship from the factory, not who performs routine service. We document every repair with photos and part numbers so you have records if a warranty claim ever arises. Call (978) 991-9492 if you’d like us to review your warranty status before we begin.
Common wear parts - pilot assemblies, thermocouples, blower motors - we carry on our trucks or can source within 2-3 business days. Factory-matched refractory panels for older 3000 Series units sometimes take 5-7 days because Olympia Chimney stocks limited quantities of legacy colors and textures. We always tell you the lead time before you commit, and we’ll recommend a safe temporary operating limit if the fireplace must stay offline.
Replace when the steel firebox wrapper is warped or rusted through, when the flue liner is incompatible with your fuel type, or when repair costs exceed 60% of a new listed insert. Repair when the issue is localized - a failed gas valve, cracked refractory, or damper cable - and the chassis is sound. We give you the numbers both ways, with photos, so you decide. Call (978) 991-9492 for a free estimate.
Gas units: annually, before heating season, to check manifold pressure, pilot integrity, and CO spillage. Wood-burning units: after every cord of wood burned, or annually if used regularly, to inspect the firebox, liner, and creosote accumulation. In Chelmsford, where many homeowners burn mixed hardwood from local suppliers, we find 18-month intervals are often too long - the wood tends to run higher moisture than kiln-dried Western species.
The risks are specific and real: a cracked heat exchanger can leak carbon monoxide into living space; a failing pilot can allow gas to accumulate before ignition; a blocked termination cap can cause combustion spillage. These are not abstract dangers - they’re what we find during tune-ups on units that “seemed fine.” The $89 Seasonal Tune-Up catches them early. Call (978) 991-9492 to schedule.
