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.

AfterOlympia Chimney Chimney Cap Installation: The Hagerstown Owner’s Guide
We stock and install Olympia Chimney-compatible chimney caps in Hagerstown, and most cap replacements run between $285 and $540 installed, depending on the flue size and whether your crown needs any patching while we’re up there. If you call before noon on a weekday, Wendell and his crew can usually have a new cap on the same week, weather permitting. Most Hagerstown homeowners find out their cap failed the hard way: brown water staining on the ceiling near the fireplace, a dead bird in the firebox, or a rust stain running down the chimney brick in the spring.
Which Olympia Chimney Models This Applies To
Olympia Chimney makes caps to fit their stainless steel liner systems, but the caps we install most often in Hagerstown are universal-fit models that work across their standard round flue sizes: 6-inch, 8-inch, and 10-inch inner diameter. The gotcha we see regularly: an Olympia Chimney cap for a 6-inch liner will not seat properly on a 6-inch clay tile flue without a transition plate. The tile is thicker, which changes the outer diameter just enough to matter. If you’re unsure what you have, take a tape measure across the inside of the flue opening at its widest point, then call us at (240) 534-1247 with that number before you buy anything online.
Top Hat Chimney is an independent service provider, not affiliated with Olympia Chimney. We stock their caps because they hold up well in Maryland weather, and because we can get OEM or quality aftermarket equivalents without waiting on a slow distributor.
Signs Your Olympia Chimney Chimney Cap Installation Is Failing
- Rust bleeding down the chimney chase or brick. The cap’s galvanized base plate has given out. Stainless lids last; the base plate is usually the first part to go in Hagerstown’s freeze-thaw cycles.
- Water pooling around the fireplace after a hard rain. Without a cap, an open flue in a summer storm can let in a surprisingly large amount of water. You’ll see it on the smoke shelf or the firebox floor.
- A cap that rattles or has shifted off-center. High winds in the valley, especially over near the Jonathan Street corridor where rooflines run tight, can loosen an old friction-fit cap. Once it rocks, it grinds, and the flue edge takes damage.
- You see daylight from inside the firebox looking up. Straight-line sight means no cap at all, or one that’s been ripped off entirely. Birds find that opening within a season.
- Soot streaks on the cap’s mesh sides. The screen is doing double duty because the cap body is undersized or warped. It’s not a fire hazard yet, but it’s not drafting right either, and that’s a repair you should not put off.
Replacement Cost & What’s Included
Plan on $285 to $400 for a standard single-flue cap installation in Hagerstown, and $400 to $540 when the flue is oversized, the crown needs a quick patch, or you’re putting a cap on two flues at once. That price includes the cap itself, the leg kit or clamp hardware, and the labor to set it level and secure it. We tell you the number on the phone and that’s the number on the invoice, no surprises when the sweep gets off the truck. Top Hat Chimney backs the work with our 90-Day Done Right Promise in writing: if it’s not right, one call brings Wendell back at no charge. Seniors and veterans always get 10% off, and any repair over $200 takes $40 off right now.
DIY or Call Us?
You can safely check a few things from the ground: is the cap still on straight, is there visible rust, does it sit flat against the crown. What you should not do is get on a roofline you don’t normally walk, especially in Hagerstown where older homes have steep pitches and some chimney crowns are softer than they look. We have pulled more than one homeowner off a ladder because the cap was friction-fit and they had no way to reseat it without the right clamp kit. If you already own the cap and it’s the right size, we’ll install it for you. If you’re not sure about the size, call (240) 534-1247 and Wendell will help you measure it over the phone.
FAQs
A stainless steel Olympia Chimney cap installed properly will last 10 to 15 years in Hagerstown before the base plate or screen needs attention, though galvanized bases can start rusting in half that time if water pools around the base. Maryland’s freeze-thaw cycles, not the fire itself, are what wear the cap out. If you see early rust, call (240) 534-1247 and we’ll tell you if it can wait or if it’s time to swap it.
Yes, if the failure is a torn screen or a loose leg, we can often repair it on the spot, but once the base plate is rusted through on an Olympia Chimney cap, patching is not worth the money because the patch will fail at the same seam. We’ll show you the camera footage and give you a plain-English verdict, every time, no exceptions.
Most single-flue cap installations take 45 minutes to an hour from the time we put the ladder up, and we’ll leave the roofline cleaner than we found it. We book a real arrival window and call if it slips.
Yes, we carry 6-inch, 8-inch, and 10-inch Olympia Chimney-compatible caps on the truck, along with DuraFlex, HeatShield, and Gelco parts for liner work. If your flue is an odd size, we can have the right cap in hand within a few days and install it the same week.
If you need a chimney cap looked at in Hagerstown, call (240) 534-1247 and Wendell or one of the crew will pick up. You’ll get a straight answer on the phone, a fair price before any work starts, and a name you can recognize at the hardware store on Saturday. If it does not need doing, Wendell will tell you that first.
