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 Roanoke Owner’s Guide
An Olympia Chimney chimney cap installation in Roanoke typically runs $280 to $550 for a standard single-flue cap with proper measuring, fitting, and weather sealing, with most jobs completed in one visit. We stock common Olympia Chimney cap sizes on our trucks and can match the exact series and flue diameter to your existing system. Most homeowners realize their cap is failing after finding rust flakes in the firebox, hearing animal scratching above the flue, or noticing water stains on the ceiling near the chimney breast after a hard Roanoke rain.
Which Olympia Chimney Models This Applies To
Olympia Chimney manufactures several cap series, and the right match depends on whether your system uses their standard galvanized line, the 304 or 316 stainless steel series, or the copper architectural caps they offer for historic homes. The model number is stamped on the underside lip of most existing caps, or on the original installation paperwork if you have it. Failing that, we measure the flue tile outer dimension and the crown overhang to spec the correct base and screen height.
We are an independent service provider, not affiliated with Olympia Chimney. For most Roanoke installations, we use genuine Olympia Chimney caps when the flue configuration is standard, but we also carry Gelco and Copperfield equivalents that match the same gauge and mesh spec when the original series has been discontinued or when a homeowner wants a different finish. The aftermarket caps we use meet the same 304 stainless minimum; we do not install builder-grade galvanized caps that will rot out in five years of Virginia freeze-thaw.
Signs Your Olympia Chimney Chimney Cap Installation Is Failing
- Rust streaking down the chimney face. Even stainless caps can fail at the weld seams or the base flange where creosote condensation pools. In Roanoke, the combination of humid summers and freeze-thaw winters accelerates seam corrosion that starts invisible and shows up as orange streaking on brick or siding.
- Water in the firebox after rain. A cap with a cracked or missing lid, or a base that has pulled away from the flue tile, lets water run straight down the flue. That water mixes with creosote to form acidic sludge that degrades the smoke chamber and damper.
- Animal intrusion, especially squirrels and raccoons. The ¾-inch mesh on an Olympia Chimney cap is specified to keep animals out while allowing smoke passage. When mesh corrodes or a cap blows off entirely, animals build nests that block the flue and create a fire hazard.
- Spalling brick or deteriorating mortar on the crown. A cap that is too small for the flue, or installed without proper overlap, channels water onto the crown instead of off it. We see this often on homes in South Roanoke where the original cap was sized for the flue tile but not the crown footprint.
- Downdraft smoke spillage into the room. A cap with a damaged or missing lid, or one installed at the wrong height above the flue, disrupts the pressure differential that draws smoke upward. This shows up on windy days, especially on exposed ridgelines in neighborhoods like Grandin Court.
Replacement Cost & What’s Included
| Service Item | Price Range in Roanoke |
|---|---|
| Single-flue stainless cap (standard size) | $280 - $380 |
| Multi-flue or oversized cap | $420 - $550 |
| Crown repair needed before cap install | $180 - $340 additional |
| Flue tile extension or adjustment | $120 - $220 additional |
The range depends on three things: cap size and material grade, whether the crown needs repair before a proper seal is possible, and whether we need to extend or adjust the flue tile height so the cap sits at the correct clearance. We price this upfront, before any work starts. The estimate you approve is the number on the invoice. Every cap installation carries our 90-Day Done Right Promise in writing, no arguing.
DIY or Call Us?
A homeowner can safely check whether the cap is present, whether the mesh is intact, and whether the cap shifts when pressed. Use binoculars from the ground; do not climb the roof. The danger is not the cap itself but the height, the pitch, and the fact that many Roanoke homes have composite or slate roofs that do not forgive a misplaced foot.
Installing a chimney cap requires working at roofline height with proper fall protection, sealing the base with high-temp silicone that bonds in cold weather, and verifying the cap does not obstruct draft. A cap installed crooked or with an inadequate base seal will leak worse than no cap at all. We have replaced DIY installations where the homeowner used hardware-store screws that rusted through in two seasons, or where the cap was the right diameter but the wrong base style for a square flue tile. If you are comfortable on a ladder and have a flat, low roof, you might manage it. Most call us instead. (540) 787-3302.
FAQs
A 304 stainless cap typically lasts 15 to 20 years in the Roanoke climate, though the 316 marine-grade series and copper caps can go 25 years or more. The limiting factor is usually the base seal and the weld seams, not the mesh or lid. Call (540) 787-3302 and we can inspect what you have and tell you honestly whether replacement is due.
Minor mesh damage can sometimes be patched, but a cracked lid, separated base flange, or rusted-through body means replacement. We do not recommend welding or epoxy repairs on a component that must withstand 1,200-degree flue gases and Virginia ice loading. We will show you the damage on camera and explain why repair or replacement makes sense.
Most standard cap replacements take 45 minutes to 90 minutes from ladder set to cleanup, assuming the crown and flue tile are sound. If crown repair or flue adjustment is needed, plan on half a day. We complete most jobs in a single visit because we stock the common sizes and carry the sealants and fasteners matched to your cap series.
We carry the most common single-flue and multi-flue sizes in 304 stainless, and we can source same-day or next-day for less common Olympia Chimney specs or copper finishes. When you call, tell us the model number or flue measurement and we will confirm stock before we dispatch. Estimates are free.
A clean chimney doesn’t announce itself. Neither does a problem - until it does.
If you are seeing rust, water, or animal signs, or if your cap is simply past its years, call us at (540) 787-3302. We will measure, spec, and install the right Olympia Chimney-compatible cap with photos you can see, a plain-English verdict, and a price that does not change. The 90-Day Done Right Promise applies to every job, in writing, no arguing.
