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 Boston: What to Know First
We clean and sweep Olympia Chimney systems throughout Boston, and most jobs are completed in a single visit of 90 minutes to two hours. A standard chimney cleaning and sweep for an Olympia Chimney flue in Boston runs $229 to $389, depending on creosote class and accessibility. You’ll get a written price before we touch the roof, and every visit includes a camera-scan inspection with a documented photo record, per Clause 4 of the Haven Standard.
This page is for Boston homeowners who own an Olympia Chimney liner or chimney system and want it cleaned properly, not just scraped. We’re an independent Olympia Chimney service provider. We are not affiliated with or authorized by Olympia Chimney, and that’s a good thing: it means we report what the camera shows, not what a warranty department wants us to say. Call (857) 567-8887 for a free estimate with a written scope and firm price. Corrine Halstead and our Boston crew answer live.
How Olympia Chimney Products Fail - and How We Fix Them
Olympia Chimney makes solid stainless steel liners and components, but Boston winters and real burn habits create failure patterns we see repeatedly. Here’s what we find on Olympia Chimney systems across Dorchester, Roxbury, Hyde Park, and the South End:
- Olympia Chimney 316L flexible liner: pitting at the lower 18 inches. Condensate from wood and gas appliances pools near the tee and eats at alloy that’s rated for solid fuel but not acidic condensation. We see this most on Olympia Chimney liners connected to gas inserts. Our fix: camera-scope the lower run, document pitting depth, and clean with an acid-neutralizing treatment before recommending liner replacement only if the metal is actually compromised.
- Olympia Chimney rigid liner sections: seamed joints loosening after 7 to 10 years. Thermal cycling in New England winters expands and contracts the seams. The result is creosote-oozing joints (often Class II to Class III buildup) that don’t respond to a standard brush sweep. Our fix: seam-by-seam camera documentation, a rotary whip pass at the joint line, and written notes on which joints will need resealing within the next two seasons.
- Olympia Chimney rain caps: mesh clogging in weeks, not months. Boston’s elm and oak pollen seasons mix with soot to pack the spark-arrestor mesh on Olympia caps. That blockage throttles draft and causes smoke spill-back into fireplaces. Our fix: remove, clean or replace the mesh, and photograph the before and after so you can see the air gap is restored.
- Olympia Chimney tee snout blockages on through-wall installations. In Boston triple-deckers and row houses, through-wall setups angle the tee where creosote and construction debris accumulate faster than a straight vertical run. This is one of the most common causes of “smells like smoke” complaints we get in Dorchester Avenue properties. Our fix: screen and snout clean, followed by an end-to-end camera pass to confirm the full flue path is clear.
- Olympia Chimney flashing and storm collar: seal failure at the roof line. We don’t just sweep the inside. On roof-access jobs, our techs inspect collar condition and caulk continuity because a failed collar lets rain run down the outside of the liner, which then flashes spalling and rust streaks down the interior. Our fix: re-seal with the correct high-temp silicone and note in writing whether the collar should be replaced within the year.
Our Olympia Chimney Chimney Cleaning & Sweep Process

- 1
Call and booking. A live person answers at (857) 567-8887, we confirm your Boston address, and we schedule a two-hour window with a text when your named tech is on the way.
- 2
Pre-sweep camera scan. Before any brush touches the flue, we run the camera down and record the baseline. That’s the only way to spot a pre-existing defect and protect both sides of the job.
- 3
Creosote class and written price confirmation. We measure the creosote class (Class I, II, or III) and tell you the exact sweep price in writing before work begins. No surprise add-ons.
- 4
The sweep. We use rotary whip and brush systems sized to the Olympia Chimney liner diameter, not a hammer-drill-and-chains setup that can dent thin-wall liner.
- 5
Post-sweep camera scan and photo report. We run the camera again, compare images to baseline, and hand you a documented photo record, per Clause 4 of the Haven Standard.
- 6
Written warranty and next-step scope. If we see early-stage liner pitting or a failing collar, we write it up with a price and a calendar recommendation, not a pressure pitch. You decide.

FAQs
Expect $229 to $289 for a standard single-flue sweep on an Olympia Chimney liner in Boston. Heavy Class III creosote runs $329 to $389. We give you a written price before work begins, and every sweep includes the camera inspection and photo record at no extra charge. Call (857) 567-8887 for a firm quote.
Not always. Minor pitting (under 1 mm depth) in the lower 18 inches of a 316L liner can often be managed with a thorough sweep and annual monitoring. We only recommend liner replacement when the camera shows perforation, separation at seams, or measurable wall thinning that affects draft or safety. You’ll see the photos before any recommendation is made.
Annually if you burn wood, and every two years at minimum if you burn gas or run a gas insert. Boston’s humidity and cold cycling create faster creosote adhesion than dryer climates, and a single season of ignored buildup can push most Olympia Chimney systems into Class II creosote quickly. We set calendar reminders for every customer.
Three things, in order: creosote builds to Class II or III, then draft drops and smoke starts spilling back into the room, then the creosote becomes fuel for a chimney fire that no liner can safely contain. It’s not fear-mongering. It’s the physical sequence. Call (857) 567-8887 if it’s been more than two seasons and we’ll run the camera before you decide.
No. Olympia Chimney warranties cover material defects in the liner and components, not the cleaning process. What can void a warranty is improper installation or mechanical damage during a bad sweep, which is why we use rotary whip sizing matched to your liner diameter and document the flue before and after with photos. We do not use chains, hammers, or any method that dents thin-wall stainless.
