Olympia Chimney Chimney Sweep in Fresno: What to Know First
An Olympia Chimney chimney sweep in Fresno typically costs $189 to $289 for a standard open-flue fireplace, with most jobs completed in 60 to 90 minutes from setup to final vacuum. That price includes a full Level 1 inspection of your Olympia flue system, creosote and soot removal, and a written report on what we found. We’re an independent Olympia Chimney service provider in Fresno, not a manufacturer call center, which means we tell you what your system actually needs and nothing more.
This page is for Fresno homeowners with an Olympia Chimney fireplace, stove, or insert who want a sweep that respects both their chimney and their schedule. You’ll get straight numbers, the real failure modes we see in Olympia systems across the San Joaquin Valley, and a clear picture of who shows up at your door. Call (559) 215-1714 to book or to talk through what you’re seeing in your firebox.
How Olympia Chimney Products Fail – and How We Fix Them
Every chimney brand has its habits. Olympia Chimney products are built well, but after enough Fresno burn seasons we see the same patterns repeat. Here’s what actually shows up on our camera screens:
- Olympia stainless steel liners (the 316L alloy used in their flex and rigid systems): In Fresno’s dry heat, the liner itself rarely corrodes the way coastal systems do, but the seams collect creosote unevenly. When a homeowner burns a lot of low-and-slow fires, glaze forms at the seam ridges first. We see this on Olympus and Chateau series units specifically. Our fix is a mechanical sweep with poly brushes sized to the liner, followed by a camera pass to confirm the seam valleys are clear.
- Olympia cast-iron dampers on their masonry fireplace kits: The pivot points get sticky from soot and fine ash, and that’s when people force the lever and crack the casting. We’ve seen it on Olympia’s masonry throat dampers more than any other component. During a sweep we remove the damper gate, clean the seat and pivot points, and test the action before reinstalling.
- Olympia air-cooled chimney pipe on prefab units: The air channel between the inner and outer wall draws ash dust and nesting debris from the cap. When the cap screen is even partially blocked, the cooling airflow drops and the pipe runs hotter than it should. On Sweep Time calls for Olympia prefab fireplaces, we always remove the cap and clear the cooling channels, not just the flue interior.
- Creosote buildup concentrated at the smoke shelf on Olympia masonry fireplaces: The angled shelf behind the damper is a natural trap, but Olympia’s firebox geometry has a slightly narrower throat than many competitors, which means buildup happens faster there. Our sweep includes a hand-scrape of the smoke shelf and a mirror check so we can show you the before-and-after.
- Olympia glass door frames on their fireplace enclosures: The glass isn’t the issue; the frame channels fill with fine white ash and the gasket degrades from heat cycling. That’s a chimney sweep adjacent-check we do on every Olympic door set we encounter. If the gasket is compromised we’ll tell you, with a replacement price in writing before any work proceeds.
Styles & brands we work with





Our Olympia Chimney Chimney Sweep Process
- 1
Booking and identification: You call, a live person answers, and we schedule the visit. Before the truck rolls, you get the technician’s name and photo by text or email. When they arrive, they show a photo ID badge. That’s the Threshold Standard, and it’s not optional.
- 2
Floor and firebox prep: We lay drop cloths, set up the vacuum with HEPA filtration, and cover your furniture within eight feet of the hearth. Your floors don’t get the ash, and neither does your living room air.
- 3
Visual inspection and camera run: We run a camera up the Olympia flue before we touch it with brushes. Ruben Castellano is known for telling you what he’s seeing while the camera image is still on the screen. If you’re home, you’ll see it too.
- 4
Mechanical sweeping: We brush from the top down when safe access allows, or bottom up with a rotary system when the roof pitch on your Fresno home warrants it. We scrape the smoke shelf, clear the damper, and remove the cap for a proper clean.
- 5
Parts decision: If we find a problem, we show you the camera image and give you a written price for the repair before any work starts. For Olympia systems, we use OEM parts when the warranty is active and equivalent trade-grade parts when it’s not. You decide.
- 6
Final test and guarantee: We run one more camera pass, test the damper, and confirm airflow. Then you get a written report and our 365-Day Done Right Promise: if the work isn’t right, we make it right. If a repair we did fails within a year, the second visit is free.

AfterWhat Olympia Chimney Chimney Sweep Costs in Fresno
Here’s what we actually charge, in writing, before we touch a single tool:
- Standard Olympia fireplace sweep (Level 1 inspection included): $189 to $289 depending on flue height and creosote stage.
- Heavy creosote removal (Stage 2 or 3 glaze): $325 to $475. Glaze from years of slow fires is more work to clear and takes specialized tools.
- Olympia wood stove or insert sweep: $215 to $315. The tighter firebox and angled flue path add time.
- Level 2 camera inspection (buying a home or after a chimney fire): $249 to $349 when booked with a sweep, $299 to $399 standalone.
What moves the price: creosote condition, flue height, roof access difficulty, and whether animals have nested in the cap or upper flue. You’ll get the exact number in writing before we begin. Call (559) 215-1714 for a free estimate.
Why Fresno Homeowners Call Alcott Chimney Fresno for Olympia Chimney Work
We’ve been serving Fresno since 2002, and our technicians know Olympia systems the way a good mechanic knows a specific engine. That matters because Olympia’s quirks are specific: the throat geometry on their masonry kits, the cooling channels on their air-cooled pipe, the seam behavior on their liners. A technician who treats every fireplace the same misses those details, and you pay for the miss later.
Every tech who arrives at your door has passed a background check and identity verification, so you know the person you saw in the photo is the person standing on your porch. You get a written price before any work, a written guarantee on every repair, and a live person on the phone any hour of the day. And because we also work with DuraFlex, HeatShield, and Gelco product lines, when a Fresno home has mixed-brand setup (Olympia in the living room, DuraFlex in the family room) we handle both the same day. Ruben Castellano built this company on a simple standard: “Tell me what you’re seeing and I’ll tell you what it actually means.” That’s still how we run every job.
FAQs
Sweep your Olympia Chimney fireplace once per cord of wood burned, or at minimum once per burn season, whichever comes first. In Fresno, most families burn 20 to 35 fires per season, which means one annual sweep is usually right. If you burn compressed logs or pine, you may need two. Call (559) 215-1714 and we’ll help you figure out your actual burn rate.
A properly performed mechanical sweep does not void an Olympia Chimney warranty, and skipping regular sweeps is the quickest way to create a warranty denial for creosote-related failures. We use poly brushes sized correctly for Olympia liners and pipe, and we document every job with camera images so you have a maintenance record if the manufacturer ever asks. If your system is still under warranty we’ll flag that and use OEM-spec procedures.
Most common Olympia parts, like damper assemblies and cap screens, are stocked in our Fresno service vans and can be replaced the same day as your sweep. Casting replacements for a cracked damper gate sometimes take three to five days to source. We’ll give you the exact availability and a written price before we start anything.
Burning it out doesn’t work for thickened creosote; it only bakes the softer tar into hardened glaze that’s harder and more expensive to remove, and in the worst case a burn-out attempt becomes a chimney fire you can’t control. Glazed creosote removal costs two to three times a standard sweep ($325 to $475 instead of $189 to $289). The math favors the annual sweep. Call (559) 215-1714 to get on the schedule before fall.
A Level 1 inspection checks the readily accessible parts of your Olympia flue and firebox, which we include with every standard sweep at no extra charge. A Level 2 inspection adds a full camera scan of the interior flue and is what you need after a chimney fire, before changing fuel type, or when buying a home in Fresno. Level 2 runs $249 to $349 when booked with a sweep.
