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.

How Olympia Chimney Products Fail - and How We Fix Them
Olympia Chimney builds solid stainless and galvanized flue systems, but every product line has its own habits. Here’s what we see in Catonsville homes, from the Patapsco Valley side over to the 40 West corridor.
- Olympia Galva-Temp air-cooled chimney pipe and heavy creosote. Galva-Temp is a galvanized air-cooled pipe that works fine when the fire burns hot. The trouble starts when a homeowner burns unseasoned wood or keeps the damper mostly closed. Creosote condenses inside the outer wall, and because the pipe has an air gap, the surface never gets hot enough to burn it off. The result is a sticky glaze that a standard brush won’t fully remove. We see this a lot in older Catonsville colonials with masonry fireplaces retrofitted with Galva-Temp runs in the chase. Our fix is a slower pass with chemical treatment, not just elbow grease, then a camera check to confirm the wall is clean.
- Olympia Forever Flex liner and third-degree creosote glaze. Forever Flex is Olympia’s 316L stainless liner, and it’s a good product. But no liner survives years of cool-burning fires without buildup. The flex corrugations are the problem: creosote packs into the valleys between ribs and hardens into a glaze that a rotary brush can polish right past. We run a poly brush or chain whip through these depending on severity, then inspect with a camera to make sure we got the valleys, not just the ridges. First-degree creosote is a brush job. Third-degree is a glaze. That’s the difference between a $200 clean and a $500 clean, and we’ll tell you which one you have before we start.
- Olympia chimney caps rusting from Catonsville humidity. Olympia factory caps do fine in dry climates. Catonsville sits in a humid belt off the Patapsco, and galvanized caps take a beating. Rust starts at the weld points, and once the mesh rots out, birds and squirrels take the invitation. The cap is not a failure that ruins the flue, but it lets critters and rain in, which then turns creosote into a tar the brush cannot move. We’ll check the cap on every sweep and tell you if a replacement is needed. Usually we can match the OEM part; if not, we use a quality aftermarket replacement from a brand like DuraFlex that’s built for this climate.
- Improper oil-flue conversion on older Olympia systems. We run into older Olympia oil flues in Catonsville homes that converted to gas twenty years ago. The homeowner assumed a sweep was optional, so the old soot sat there for two decades. Oil soot is acidic. It eats stainless after enough time. When we finally get in there, the liner shows pitting, and sometimes the owner needs a HeatShield resurfacing or a new liner rather than just a clean. The failure is not the product; it’s the skipped maintenance. Once a year, burn or no burn. Chimneys break in the off-season too.
- Olympia anchor plates with missing silicone at the crown. The anchor plate where the liner terminates is supposed to be sealed against the crown. Silicone dries and separates over Maryland winters. Water gets under the plate, runs down the outside of the liner, and sits on the firebox top. The owner sees a musty smell in summer and thinks creosote; it’s actually water-damaged creosote, which is a different animal. We’ll reseal the plate, clean the flue, and tell you honestly if the crown itself needs work before the water problem gets worse.
Our Olympia Chimney Chimney Cleaning & Sweep Process
Here’s the whole job, start to finish, so you know what happens when we come out.
- 1
You call (443) 332-7798. A live person picks up, day or night. It might be Wendell himself. We ask what Olympia product you have, what you’ve been burning, and when the last sweep happened.
- 2
We give you the price before we load the truck. The number we quote on the phone is the number on the invoice. If we get there and the flue is worse than expected, Wendell calls you before any work changes hands and tells you plainly what it will cost.
- 3
We set up and inspect the firebox and flue. Drop cloths go down, the vacuum gets positioned, and we shine a light up the flue to see what we’re dealing with. This is where we catch the Olympia-specific issues: cap rust, anchor plate silicone, glaze in the flex ribs.
- 4
We sweep with the right tool for your product. Galva-Temp gets a poly brush and chemical treatment if needed. Forever Flex gets a brush or chain whip sized to the corrugations. No shortcuts, no polishing over the glaze.
- 5
Camera in, no exceptions. After the brush work, the camera goes up. You see the footage. We walk you through what we’re looking at in plain English. The camera footage and a plain-English verdict, every time.
- 6
Cleanup and the Done Right Promise. We leave the hearth cleaner than we found it, and the 90-Day Done Right Promise goes with every job. If something isn’t right, one call brings Wendell back.

FAQs
No. As an independent Olympia Chimney service provider, we clean and repair these systems without affecting the manufacturer’s warranty. We use OEM parts when they’re the right call and available, and quality aftermarket alternatives when the OEM part is backordered or overpriced. We’ll tell you which we’re using and why before we install anything.
Once a year, burn or no burn. That’s true for every Olympia product we service, whether it’s Galva-Temp pipe in a chase or a Forever Flex liner. Catonsville humidity makes creosote stickier in summer, and off-season moisture turns soft soot into a glaze that’s harder and more expensive to remove. If you burn more than two cords a year or burn green wood, twice a year may be the better call. Call (443) 332-7798 and we’ll tell you honestly whether you need a sweep this season or can wait.
Yes, and you’ll see it with your own eyes. After every sweep, we run a camera through the flue. If the liner is pitted, cracked, or rusted through, you’ll see it on the screen. If it just needs a clean, you’ll see that too. Nothing gets recommended without camera evidence you can look at yourself.
That smell is usually creosote that absorbed moisture over the Maryland summer, sometimes with water getting under the anchor plate or a failing cap. The fix starts with a sweep to get the creosote out, then we check the cap and the plate seal. Sometimes the crown needs re-sealing. We’ll show you the problem on the camera and tell you exactly which repair is needed and which one can wait.
Usually within a week, sometimes sooner in the fall rush. A sweep is not an emergency call, and quoting same-day service makes us no better than the chains that frustrate you in the first place. The urgency is seasonal: before burning season, not the afternoon before you light the first fire. Call (443) 332-7798 and we’ll slot you in at the first open time, which is typically soon.
If you own an Olympia Chimney fireplace, liner, or pipe anywhere in Catonsville, you already know the product is good. It just needs a sweep who knows its habits. Wendell Pike has been inside these flues for over two decades, and he’ll tell you straight if the job needs doing or not. If it needs doing, we will do it right. If it does not, I will tell you that too. Call (443) 332-7798 for a free estimate. The price we quote is the price you’ll pay, and every job carries the 90-Day Done Right Promise in writing.
