Olympia Chimney Chimney Sweep in Houston: What to Know First
An Olympia Chimney chimney sweep in Houston typically runs between $189 and $329 for a standard open fireplace, and we book most appointments inside a week. The price covers a full flue cleaning, a safety check of the firebox and damper, and a written condition report before we leave. If you own an Olympia Chimney fireplace or venting system, you’ll also want a sweep who knows how their liners and caps wear in Houston’s humidity, because that’s where the real problems hide. Call (903) 961-6496 and we’ll give you a written price before anything gets touched.
This page is for homeowners who cook on, heat with, or just enjoy an Olympia Chimney fireplace and want to know what a proper sweep involves, what it costs, and what can quietly go wrong between cleanings. We’ve worked on Olympia Chimney products across Houston for years, from older masonry fireplaces in Garden Oaks to prefab units in Katy and Sugar Land, and we see the same patterns repeat. Here’s what we know.
How Olympia Chimney Products Fail, and How We Fix Them
Olympia Chimney makes solid equipment, no argument there. But every brand has failure points that show up only after years of use, and in Houston, the climate adds its own fingerprints. These are the five we run into most on sweep jobs.
- Air-cooled chimney pipe with creosote-glazed inner walls. On Olympia’s older air-cooled venting systems, the inner stainless wall runs hot enough to bake creosote into a hard, glassy layer that a standard brush won’t remove. We see this constantly on wood-burning prefab fireplaces that get used four or five nights a week in December and January. The fix is a slow, deliberate sweep with a stiffer brush, sometimes two passes, followed by a camera check to confirm the flue is actually clean, not just brushed.
- Flashing and storm collar leaks at the chase top. Houston gets real rain, and when an Olympia Chimney chase top flashing wasn’t sealed properly at install or the storm collar has shifted, water follows the pipe down into the chase. The first clue is usually a rust stain on the ceiling near the fireplace or a musty smell when the AC kicks on. During a sweep, we inspect the chase top and collar as standard, because a clean flue doesn’t matter much if water is quietly eating the framing.
- Damaged refractory panels in zero-clearance fireboxes. Olympia zero-clearance units often use refractory brick panels that look fine until the fireplace runs hot, then hairline cracks start. Those cracks let heat reach the metal firebox shell, which was never meant to take direct flame. We check panel condition on every sweep and flag cracks with photos, because replacing a panel now costs a fraction of replacing the firebox later.
- Clogged or blocked termination caps on prefab systems. On Olympia direct-vent and vent-free setups, the termination cap is the exhaust system’s only way to breathe. Houston squirrel and bird pressure is constant, and we’ve pulled nests, leaves, and even a toy action figure out of capped chimneys. A blocked termination cap pushes carbon monoxide back into the living space instead of out. That’s not a scare line, it’s physics. We clean and clear caps on every sweep and recommend a screened cap if yours doesn’t have one.
- Creosote buildup in short, cold flues. Many Houston homes run short chimney stacks, which means exhaust gases cool faster and drop creosote sooner than in colder climates. Olympia Chimney systems are no exception. A flue that sees only occasional fires can still accumulate enough Stage 2 creosote in one season to be a fire risk. We rate what we remove, show you photos, and tell you honestly whether you need two sweeps a year or one is plenty.
Styles & brands we work with





Our Olympia Chimney Chimney Sweep Process
We’re an independent Olympia Chimney service provider. We don’t have a parts rebate arrangement with them, and we don’t need one. What we have is experience with their products and a process that doesn’t skip steps. Here’s how a typical job runs.
- 1
You call, a person answers. No phone tree. We ask basic questions about your fireplace type and last sweep, then schedule a two-hour arrival window that we actually keep. Nathan Corliss runs the crew and he’s been on a roof more times than he can count. The crew shows up in uniform and introduces themselves.
- 2
We look before we touch. We inspect the firebox, damper, smoke shelf, and accessible flue from below, then check the chimney from the roof. If we see cracked panels, water intrusion, or a blocked cap, we photograph it.
- 3
We write the price. Before any work begins, you get a written quote. If the sweep is all you need, that’s the number on the invoice when we’re done. If we find something else, we show you the photo and explain what it means. You decide.
- 4
We run the sweep and contain the mess. We use tarps, HEPA vacuuming, and brushes matched to your flue type. Olympia Chimney air-cooled systems get a gentler pass on the inner wall, while masonry flues with heavy Stage 2 creosote get a more aggressive mechanical cleaning. Ash stays in the fireplace, not on your couch.
- 5
We test and document. We run a draft check, verify the damper opens and closes fully, and do a final visual from the roof. You get a written condition report with photos and any recommendations, in plain English.
- 6
We leave it cleaner, guaranteed. The Kingswell Guarantee applies to every repair we make. If a covered repair fails, we return and fix it at no charge. That’s the 365-Day Done Right Promise. Tell you the price first, explain the work second, put it in writing third, that’s the whole system.

AfterWhat Olympia Chimney Chimney Sweep Costs in Houston
Most Olympia Chimney chimney sweeps in Houston run between $189 and $329. The spread comes down to flue type, creosote stage, and whether you need anything beyond the standard clean. Here’s what that looks like in real dollars.
- Standard open fireplace sweep: $189 to $249. Includes flue cleaning, damper check, firebox inspection, and written report.
- Prefab or zero-clearance unit with Olympia Chimney air-cooled pipe: $229 to $289. The pipe takes more time to clean properly without damaging the inner wall.
- Heavy creosote or glaze removal (Stage 2 or 3): $289 to $379. Requires stiffer brushes, sometimes a second pass, and a camera confirmation.
- Level 2 inspection add-on (camera scope): $149 to $199. Worth it if you just bought the house or haven’t swept in four-plus years.
What moves the price: roof pitch and access, critter removal if we find a nest, a missing or damaged cap, and whether the damper needs repair. We quote before we work, and the quote doesn’t change unless you add work. Call (903) 961-6496 and we’ll give you a real number over the phone, not a “we’ll see when we get there.”
Why Houston Homeowners Call Ashby Chimney Houston for Olympia Chimney Work
Because a lot of chimney companies in Houston will clean your flue and vanish. We’re not that company. We’ve been doing this since 2002, and our whole model is built around the opposite of what makes people gun-shy: a written price before work starts, a written guarantee when it’s done, and a real person who answers the phone at 2 a.m. if you’re worried about a smell. Our techs are background-checked and uniformed, so you know exactly who’s in your home. We carry DuraFlex, HeatShield, and Gelco products alongside Olympia Chimney parts, which means when your Olympia cap is discontinued or backordered, we can usually offer a viable alternative instead of leaving you without a functioning fireplace for six weeks. That multi-brand fluency is the edge you want when a manufacturer line changes hands or a part goes out of production. Nathan grew up in Los Angeles and trained at Los Angeles Trade-Technical College, and he’s been working Houston rooftops long enough to know which chase tops in Meyerland hold water and which ones don’t. We answer the phone, we show up, and we stand behind the work in writing.
FAQs
How often should I have my Olympia Chimney fireplace swept in Houston? Every 30 to 50 fires, or at least once a year if you burn wood, even in a mild Houston winter. Gas log setups still need an annual check for dust, spider webs in the burner orifices, and venting blockages, though they don’t build creosote. The National Fire Protection Association recommends an annual inspection regardless of fuel type. Call (903) 961-6496 and we’ll help you set a sensible schedule based on how you actually use the fireplace.
Do I really need a camera inspection, or is a visual sweep enough? For an Olympia Chimney prefab unit, we recommend a camera scope at least every other sweep. The air-cooled pipe inner walls are where hidden damage and creosote glaze live, and you can’t see that from the roof or the firebox. A camera shows you exactly what we’re seeing. If the camera finds nothing, you’ve paid $149 to $199 for certainty. If it finds a crack or separation, it just saved you a chimney fire.
Can you get Olympia Chimney parts, or do I have to go through the manufacturer? We handle parts sourcing for you, and we’re an independent Olympia Chimney service provider, so we’re not restricted to their catalog. If an Olympia part is on backorder or discontinued, we’ll tell you straight, then show you a comparable option from DuraFlex, HeatShield, or Gelco that does the same job. You always approve the part and the price before we install anything.
What happens if you find a crack or other problem during my sweep? You get a photo and a plain-English explanation. We don’t manufacture problems, and we don’t push repairs you don’t need. If it’s safe to wait, we say so. If it’s not, we explain why and give you a written quote. The decision is always yours. Every repair we do carries the Kingswell Guarantee, and if it fails within the guarantee period, we return and fix it free.
How fast can you get to my Olympia Chimney fireplace in Houston? Most standard sweeps are booked within a week, and since our phones are answered live 24/7, you’ll get a real person and a real time window the first time you call.
