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 Baltimore: What to Know First
We provide independent Olympia Chimney chimney cleaning and sweep services throughout Baltimore, with most Level 1 and Level 2 inspections completed in a single visit and pricing agreed before we start. A standard Olympia Chimney sweep and inspection in Baltimore typically runs $180-$320, depending on creosote buildup severity and whether a camera inspection is needed. We’re not affiliated with Olympia Chimney - we’re an independent service provider that happens to know their product lines from years of hands-on work in Baltimore’s older housing stock.
This page is for homeowners in neighborhoods like Canton, Fells Point, Hampden, and the rowhouse blocks near Patterson Park who have an Olympia Chimney liner, cap, or venting component and need it cleaned, inspected, or diagnosed honestly. If that’s you, call (410) 849-6273. A live person answers, 24 hours a day.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney 316Ti stainless liners and creosote glazing in Baltimore’s freeze-thaw cycles. The 316Ti alloy resists corrosion well, but Baltimore’s wet winters and sudden temperature drops can accelerate glazed creosote formation, especially in liners serving older masonry fireplaces with poor draft. We use rotary polypropylene whips followed by chemical treatment for stubborn glaze, then verify clearance with a camera before signing off.
- Olympia Chimney round flex liners that lose tension in tall Baltimore rowhouse flues. The 25-foot and 35-foot flex kits common in three-story Canton and Federal Hill homes can sag at connection points after years of thermal cycling. During sweep and inspection, we check for ovalization and draft loss; if the liner has dropped, we re-tension and re-secure with Olympia-compatible top plates or, when the original hardware is fatigued, upgrade to a DuraFlex termination.
- Olympia Chimney pellet vent systems with ash accumulation in horizontal runs. The PVL series pellet vents, popular in Baltimore County retrofits, have smooth-wall interiors that still collect fine ash at elbow joints. We disassemble accessible sections, vacuum with HEPA filtration, and reseal with fresh gaskets - not generic caulk, which voids the vent’s UL listing.
- Olympia Chimney wind-directional caps that seize in coastal salt air. Homes near the Inner Harbor or Middle River see accelerated corrosion on the pivot bearings of Olympia’s wind-directional models. We remove, clean, and assess; if the cap is salvageable, we lubricate with high-temp graphite. If the pivot is frozen, we replace with a Gelco or Famco equivalent that matches the flue diameter and maintains proper draft dynamics.
- Olympia Chimney direct-vent gas terminals clogged with Baltimore’s cottonwood seed and urban debris. The concentric intake/exhaust terminals on Olympia’s gas systems can choke with seed fluff in late spring, causing rollout or sooting. We clear the intake screen, verify combustion air draw with a manometer, and document the reading - not just “looks clean,” but measured and recorded.
Our Olympia Chimney Chimney Cleaning & Sweep Process
- 1
Call and schedule. A live person answers at (410) 849-6273, any hour. We ask about your Olympia Chimney product line if you know it, the fuel type, and any symptoms - odd smells, draft issues, visible soot. We book a window and confirm upfront pricing.
- 2
Arrival and protection. Our technician arrives in uniform, lays drop cloths, and runs a HEPA vacuum before touching anything. We inspect the appliance and flue opening for obvious damage or code violations.
- 3
Level 1 or Level 2 inspection with camera. For routine sweeps, we perform a Level 1 visual inspection. If we find glazed creosote, liner displacement, or suspected damage, we upgrade to Level 2 - full camera inspection of the flue interior, with photos you can see on the spot and a plain-English verdict.
- 4
Sweep and component service. We match the cleaning method to the Olympia Chimney material: poly whips for 316Ti stainless, softer methods for aluminum pellet vent, hand brushes for tight offsets. We service caps, dampers, and connections as needed, using OEM or professional-grade aftermarket parts from DuraFlex, HeatShield, or Gelco when Olympia hardware is discontinued or backordered.
- 5
Testing and documentation. We test draft, check for proper clearances, and run a final camera pass if work was performed inside the flue. You receive photos, findings, and any recommendations in writing - no surprises, no pressure.
- 6
Cleanup and guarantee. We vacuum again, remove protection, and leave the work area as we found it. Every job is covered by our 90-Day Done Right Promise: in writing, no arguing. If it’s not right, we come back.

Why Baltimore Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We’ve been sweeping chimneys in Baltimore for over 42 years, and we’ve learned that the flue doesn’t care about brand loyalty - it cares about whether the person working on it understands how that particular product behaves in this particular climate. Russell Haines and our crew know Olympia Chimney’s product evolution, which parts cross-reference to DuraFlex and Gelco when Olympia discontinues a line, and when a repair can wait versus when it can’t.
Our 90-Day Done Right Promise means if we miss something, we make it right - in writing, no arguing. Calls are answered by a live person, 24 hours a day. Technicians are background-checked and uniformed. Most jobs finish in one visit. And nothing is recommended without camera evidence you can see for yourself. If the flue is right, the fire takes care of itself.
FAQs
No - manufacturer warranties on chimney components cover defects in materials and workmanship, not who performs routine maintenance. We document our work with photos and written findings, which actually supports any future warranty claim you might need to file with Olympia Chimney. Keep your service records. Call (410) 849-6273 if you’d like us to review what’s documented from your last sweep.
Cleaning addresses soot and creosote buildup; repair addresses physical damage like cracks, separation, or corrosion spots. During our Level 2 camera inspection, we show you the difference in real time. If the liner is dirty but intact, we sweep it and you’re set for the season. If we find a breach or thinning wall, we explain exactly where and why, and we only recommend replacement when the camera evidence supports it. Call (410) 849-6273 to schedule an inspection.
OEM parts are preferred for exact fit and warranty continuity, but Olympia Chimney has discontinued certain cap and termination models over the years. We stock and source professional-grade equivalents from DuraFlex, HeatShield, and Gelco that match UL listings and flue specifications. We explain the trade-off before installing anything non-OEM, and we never substitute with builder-grade hardware. Call (410) 849-6273 to discuss what’s available for your specific model.
The National Fire Protection Association recommends annual inspection for all chimney systems, and sweeping when creosote exceeds 1/8 inch. In Baltimore, where many Olympia Chimney liners serve wood-burning fireplaces in drafty old masonry, we find that heavy-use households need sweeping every year, while occasional users can sometimes stretch to every two years - confirmed by camera, not by guess. Call (410) 849-6273 and we’ll tell you honestly where you stand.
Skipped maintenance leads to accumulated creosote, which ignites at 451 degrees and can damage the liner, surrounding masonry, or worse. In Baltimore’s tight rowhouse construction, a chimney fire spreads fast. Carbon monoxide risk also rises if a vent is partially blocked. That said, we don’t scare-sell - we inspect, we show you what we find, and we tell you whether the risk is immediate or manageable until next season. Call (410) 849-6273 for a free estimate and an honest read on your flue.
