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 Rockville: What to Know First
Olympia Chimney cleaning and sweep in Rockville runs between $189 and $325 for a standard open-flue fireplace, depending on creosote buildup, flue height, and whether you’re due for just a sweep or a full Level 2 camera inspection. Most jobs are done within two hours from the time Wendell or one of his crew pulls up to the curb. We’re an independent Olympia Chimney service provider, not a manufacturer affiliate, which means we call it like the camera sees it and charge you the number we quoted before a single tool comes off the truck. If you own an Olympia fireplace or wood stove in Rockville and want a sweep who knows the brand, call (240) 716-5865.
How Olympia Chimney Products Fail — and How We Fix Them
Olympia builds decent fireplace and chimney components, but they fail in predictable ways around Rockville. We’ve been inside enough of them since 1999 to know exactly where to look. These aren’t theoretical failure modes. They’re what we find on service calls:
- The Olympus Series fireplace damper clamps. The cast-iron damper plate on Olympia’s Olympus zero-clearance fireplaces tends to seize in place after repeated heat cycles. When it won’t fully open, combustion air gets pulled from other places, pulling more creosote into the flue. We free the damper assembly, check the pivot rods, and sweep the flue properly — a two-step fix most homeowners don’t get from a brush-only sweep.
- Creosote glazing at the smoke shelf. Olympia’s smoke shelves on their masonry adapter kits have a sharp bend that accumulates thick, hard second-degree creosote in Rockville’s humid shoulder seasons. This is exactly what a camera inspection catches before it becomes a chimney fire. We scrape and brush that shelf by hand, every visit.
- Leaky Olympia multi-flue caps over Rockville’s three-story runs. The factory screen mesh on Olympia’s multi-flue caps corrodes after a few winters of freeze-thaw, letting squirrels and starlings nest in dead flues. We pull the cap, inspect for animal staining, clean out the debris, and replace with a properly sized cap if the old one’s rusted through.
- Warped refractory panels on older Olympia Ventis fireplaces. These panels crack and bow after years of hot fires, leaving gaps that let heat reach framing. During a sweep, we’re trained to spot panels that need replacement before they become a bigger repair.
- Wet ash accumulation in exterior-chase Olympia units. Rockville gets too many raw winter days, and Olympia’s exterior-chase fireplaces pull moisture into the ash bed when the chase cap weeps. Wet ash turns acidic, eats at the firebox floor, and makes every future sweep harder. We clean it out, tell you the source of the moisture, and recommend whether to reseal or reroute.
Our Olympia Chimney Chimney Cleaning & Sweep Process
Here’s what happens when you call us for an Olympia Chimney cleaning or sweep in Rockville:
- 1
You call, a live person answers. Day, night, Sunday morning — one of us picks up. We ask what you’re seeing: smoke spillage, odd smells, or just overdue for an annual sweep. Then we book a real arrival window.
- 2
Wendell or a uniformed crew member arrives. We check the firebox, damper operation, and note anything rusted, cracked, or out of alignment before we start.
- 3
We sweep with appropriately sized brushes. Every Olympia flue gets the right diameter brush and rods. No shortcuts, no skipping the smoke shelf.
- 4
Camera inspection. We run a camera down the flue after sweeping. We show you the footage on the spot and explain in plain English whether anything needs attention now, can wait, or isn’t worth touching. If it doesn’t need doing, we’ll tell you.
- 5
We leave the area cleaner than we found it. Drop cloths down, HEPA vacuum running, and no soot tracked through the living room.
- 6
You get the 90-Day Done Right Promise in writing. If the sweep isn’t done right, one call brings us back at no charge.

FAQs
No. Regular cleaning and inspection is required by Olympia’s own warranty terms. We’re an independent Olympia Chimney service provider, so we’re not authorized to make warranty determinations ourselves, but we’ll give you clear, documented notes and camera footage you can submit for any warranty claim.
Once a year, burn or no burn. Rockville’s freeze-thaw cycles and humid summers cause flues to degrade even when unused. An annual sweep catches creosote buildup before it glazes and lets us spot moisture intrusion early.
Usually, yes, for common wear items like damper gaskets, cap screens, and refractory retainers. For older Olympia Ventis or Olympus parts that are harder to source, we may need to order an OEM part and return for a second visit to complete the install.
Then we’ll tell you exactly why, with the camera footage to prove it. Sometimes a sweepplus a HeatShield resurfacing treatment buys years. Other times a new DuraFlex liner is the honest answer. We never recommend a liner you can’t verify with your own eyes.
We schedule sweeps within a few days most weeks, and we keep it moving in the fall so you aren’t burning season one fire too many. Call (240) 716-5865 and a live person will get you on the calendar. If we’re in your neighborhood, we’ve been known to show up that afternoon.
