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 Cap & Crown in Pottstown: What to Know First
We provide independent Olympia Chimney chimney cap & crown service in Pottstown, with most repairs completed in a single visit and upfront pricing agreed before we start. A standard Olympia Chimney cap replacement runs $280-$520, while crown repair or coating typically falls between $340-$780 depending on accessibility and flue count. We’re not here to sell you parts you don’t need - we’ll show you the problem on camera, explain what the fix is, and let you decide.
This page is for Pottstown homeowners who already have an Olympia Chimney system installed and need honest work on the cap or crown. If you’re seeing rust streaks, water in the firebox, or crumbling concrete at the top of your chimney, call us at (610) 819-4281. A live person answers, 24 hours a day.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney Gelco-style single-flue caps in the 13×13 and 8×12 sizes - these are common on Pottstown colonials built in the 1980s and 1990s. The 304 stainless mesh hoods hold up, but the base rails fatigue where they meet the flue tile after 15-20 winters of Montgomery County freeze-thaw. We see the rail corners crack first, usually on the north-facing side where ice lingers. We replace with either an Olympia Chimney OEM base rail or a heavier-gauge aftermarket equivalent, depending on what’s in stock and your preference.
- Olympia Chimney multi-flue caps on homes near the Schuylkill River - the wider spans (typically 17×29 or 21×37) collect more leaf debris and hold moisture against the crown below. We’ve pulled caps off in the West End where the crown was sound underneath but had developed a 3/16-inch depression right at the flue center from years of standing water. We clean and inspect the crown, reseal with CrownCoat or similar professional-grade coating, then reset the cap with proper standoff height so water sheds clean.
- Olympia Chimney outside-mount caps with integrated spark arrestors - the arrestor mesh on older units (pre-2015) uses a lighter weave that clogs with creosote faster than current spec. In Pottstown’s older housing stock with oil-to-gas conversions, we find these caps choked half-shut, which backdrafts CO into the house during shoulder season. We swap to current-mesh arrestors or full replacement caps with better airflow geometry, always checking draft pressure before we leave.
- Olympia Chimney crown-forming systems on prefab metal chimneys - the factory crown wash is thin, sometimes 3/8-inch at the edge, and it doesn’t bond well to the chase cover below after the first decade. In the historic districts near High Street, we’ve chased water intrusion back to these crowns more times than we can count. We strip to bare metal, apply a bonding primer, then build back with a proper cementitious crown mix sloped 1/4-inch per foot - not a caulk job, not a patch, but a real crown that sheds water.
- Olympia Chimney custom copper caps on higher-end installs - beautiful when new, but the solder joints at the hip ridges work loose after 12-15 years of thermal cycling. Pottstown’s summer humidity and winter cold snaps are hard on soft solder. We resolder with 95/5 tin-silver or replace the cap entirely if the copper has thinned. We keep copper stock in our shop, so most custom work doesn’t wait on a factory order.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, day or night. We book a window that works for you - no four-hour waits, no “sometime Tuesday” vagueness.
- 2
Level-2 camera inspection on arrival. Our tech photographs the cap, crown, and flue interior. You see what we see on the tablet. Russell Haines trained every senior tech to read a flue quietly and thoroughly - the chimney does not lie, and neither do we.
- 3
Parts decision. If your cap is Olympia Chimney, we check whether OEM replacement makes sense or if a quality aftermarket cap from Gelco or Famco fits better for your situation. We explain the trade-offs: warranty coverage, lead time, longevity. No pressure either way.
- 4
The repair. Background-checked, uniformed technicians do the work. Most cap replacements and crown coatings finish in one visit. Crown rebuilds sometimes need a return trip for cure time.
- 5
Test and document. We run a draft test, check for leaks with a water spray, and give you photos of the completed work plus a plain-English report.
- 6
Guarantee in writing. Every job carries our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back.

Why Pottstown Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We’ve been sweeping and repairing chimneys in Pottstown and Montgomery County for over 42 years. Russell Haines has spent the better part of two decades on local roofs, including plenty of older homes near Manatawny Street where the chimneys are as stubborn as they are historic. He learned the trade at Los Angeles Trade-Technical College, then put in years of field work before the craft became second nature.
We don’t just know Olympia Chimney. We also work with DuraFlex, HeatShield, and Gelco - so if an Olympia Chimney part is backordered or a different solution fits better, we have options. Every job gets photos you can see, a plain-English verdict, and our 90-Day Done Right Promise in writing. A square deal: no surprises on the bill. We’ll be there when we say.
FAQs
No - as an independent Olympia Chimney service provider, we use manufacturer-compatible parts and practices that keep your warranty intact. We document everything with photos in case you ever need to file a claim. If you’re unsure about your specific warranty terms, call us at (610) 819-4281 and we’ll review them with you.
Most single-flue replacements take 90 minutes to two hours from ladder set to cleanup. Multi-flue caps or jobs requiring crown repair first may run three to four hours. We complete most jobs in a single visit, and we’ll tell you upfront if yours is a two-trip situation. Call (610) 819-4281 to schedule - estimates are free.
If the crown has surface cracking but no structural separation from the flue tile, a professional coating usually lasts 10-15 years. If the crown is crumbling, sloped wrong, or detached at the edges, rebuild it - coating over bad concrete is money wasted. We show you the camera footage and give you both options with real numbers. Call (610) 819-4281 for a free look.
We stock common Olympia Chimney cap sizes and keep relationships with regional distributors for faster turnaround than factory direct. For discontinued lines, we source quality aftermarket equivalents from Gelco or Famco that match or exceed OEM specs. We’ll tell you honestly if there’s a wait and what your alternatives are. Call (610) 819-4281 to check availability.
Water in the firebox, rust stains on the exterior masonry, or a damp odor after rain usually point to cap or crown failure. But we’ve also traced “cap problems” back to cracked flue liners and missing chimney shoulders. That’s why we start with a camera inspection - we don’t guess, and we don’t sell you a cap if the real problem is downstream. Call (610) 819-4281 for a free estimate and we’ll show you exactly what’s wrong.
