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.
Olympia Chimney Chimney Cleaning & Sweep in Westminster: What to Know First
We provide independent Olympia Chimney chimney cleaning and sweep services in Westminster, with most Level 1 and Level 2 inspections completed in a single visit and upfront pricing agreed before we start. A standard sweep and inspection for an Olympia Chimney system in Carroll County typically runs $189-$289, depending on creosote buildup and whether a camera inspection is needed. We do not quote low to get in the door and then add charges; the number on the estimate is the number on the invoice.
This page is for Westminster homeowners who heat with wood or pellets through an Olympia Chimney liner, cap, or component and want a sweep who knows the difference between a 316Ti flex liner and a 304, or why the Gelco-cap pairing on older Olympia systems tends to collect debris in our freeze-thaw climate. If that’s your chimney, call (301) 215-3355. A live person answers, 24 hours a day.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia 316Ti flexible liner, pre-2018 batches: The titanium-stabilized alloy resists acid corrosion better than standard 304, but early production runs had weld-seam inconsistencies that trap creosote in the corrugations. In Westminster, where homeowners often burn mixed hardwoods and softwoods through shoulder seasons, we’ve pulled liners with ¼-inch glazed creosote hiding in those seams. We remove it with polypropylene brushes sized to the liner’s exact pitch, then verify clear passage with a camera before we sign off.
- Olympia Chimney stainless steel caps with standard mesh: The ¾-inch mesh that ships standard clogs with leaf debris from Carroll County’s heavy oak canopy, especially on homes near Westminster’s Reservoir Hill or around the Hashawha Environmental Center. Water backs up, freeze-thaw opens crown cracks, and suddenly you’re looking at liner damage from the top down. We clean the cap thoroughly and, if the mesh is corroded, replace with a Gelco 5/8-inch mesh or a custom-fabricated Famco cap that sheds debris better in our climate.
- Olympia Chimney’s proprietary top-sealing dampers: The cast-aluminum frame gasket hardens after seven to ten winters in Westminster’s temperature swings. The damper still “works” but leaks enough to let conditioned air escape and draw down creosote-laden cold air in summer. During sweep service, we inspect the seal with a smoke pencil and replace the gasket with OEM-spec silicone or upgrade to a HeatShield-compatible damper if the frame has warped.
- Olympia pellet vent systems (4-inch and 3-inch): Pellet ash is alkaline and, combined with Westminster’s humidity spikes in late spring, cakes into a concrete-like deposit in the T-connector and cleanout tee. Standard wire brushes score the inner wall; we use nylon pellet-specific whips and vacuum extraction, then inspect with a borescope to confirm the venturi passages are clear. A blocked pellet vent backdrafts carbon monoxide into the living space. We flag it immediately if we see it.
- Olympia Chimney’s air-cooled chimney systems in masonry enclosures: The air gap between the metal chimney and the brick chase collects fallen mortar, bird nesting, and decades of soot in Westminster’s pre-1980 housing stock along Main Street and Pennsylvania Avenue. The chimney “works” but drafts poorly and overheats the surrounding framing. We remove the chase cover, vacuum the gap completely, and document the condition with photos you can see before we reassemble.
Our Olympia Chimney Chimney Cleaning & Sweep Process
- 1
Call intake: A live person answers, asks what you’re burning, how often, and whether you’ve noticed draft issues or odors. We schedule a window and confirm upfront pricing.
- 2
Arrival and protection: Our technician arrives in uniform, lays drop cloths from the door to the hearth, and runs a HEPA vacuum before touching anything. Background-checked, every one of them.
- 3
Level 1 or Level 2 inspection: We assess the Olympia Chimney components against NFPA 211 standards. If we suspect concealed damage, we recommend the Level 2 camera inspection and show you the monitor in real time.
- 4
Cleaning with brand-appropriate tools: Poly brushes for 316Ti liners, nylon whips for pellet vents, hand tools for tight smoke chambers. We use Copperfield rods and brushes, never hardware-store substitutes that shed bristles in your flue.
- 5
Parts decision and documentation: If we find a failed gasket, corroded cap, or liner breach, we explain the OEM-versus-quality-aftermarket trade-off for your specific Olympia component. No recommendation without photo evidence you can see for yourself.
- 6
Final test, written report, and guarantee: We run a draft test, provide a plain-English written report with photos, and every job carries our 90-Day Done Right Promise in writing. If it’s not right, we come back. No arguing.

Why Westminster Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We’ve been sweeping chimneys in Carroll County since 1984. That’s long enough to know which Westminster neighborhoods have the pre-war masonry that shifts in our clay soil, and which have the 1980s additions with Olympia liners installed too tight in the chase. Russell Haines learned this trade hands-on, and he’s built a team that documents every inspection like an engineer and explains it like a craftsman.
Our 90-Day Done Right Promise means if we miss something or a repair doesn’t hold, we make it right in writing with no paperwork and no arguing. We carry professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, so we’re not ordering parts while your heat is down. And when you call (301) 215-3355, a live person answers - every hour, every day. Most jobs finish in a single visit. That’s how we’ve stayed in business for over 42 years.
FAQs
No. As an independent Olympia Chimney service provider, we follow manufacturer specifications and NFPA 211 standards, which preserves warranty coverage. Using unqualified contractors or incorrect tools can void it, which is why we document our methods and materials in your written report. Call (301) 215-3355 if you need a copy for your records.
We source OEM when it’s the right choice and available, but we also use quality aftermarket from Famco, Gelco, and Copperfield that meets or exceeds OEM spec. We explain the trade-off for your specific part and let you decide. No surprises on the bill either way.
You can’t tell from the hearth. Creosote buildup hides liner damage, and a cracked crown often looks fine from below. That’s why we include camera inspection when we suspect concealed damage, and we show you the photos before recommending any repair. Some issues can wait a season; others can’t. We’ll tell you plainly which is which.
Once per burning season for wood-burning systems, per NFPA 211. In Westminster, where many homeowners burn from October through March and our spring humidity accelerates corrosion, we recommend inspection at shut-down. Pellet systems typically need sweep service every 1-2 tons of fuel burned. Call (301) 215-3355 to schedule around your burning schedule.
Glazed creosote becomes fuel for a chimney fire, and even a small fire can crack a 316Ti liner or damage the surrounding masonry. Carbon monoxide can then leak through those cracks. The risk is real, gradual, and invisible until it’s not. A standard sweep costs less than a deductible. Call (301) 215-3355 for a free estimate.
