Olympia Chimney Chimney Cap & Crown Nationwide

Olympia Chimney Chimney Cap & Crown in Alpharetta: What to Know First

We provide independent Olympia Chimney chimney cap and crown service throughout Alpharetta, from standard cap swaps on the 300 Series to full crown rebuilds on older 200 Series flue systems. Most Olympia Chimney jobs we book run $280 to $890 depending on whether we’re fitting a new cap, coating a cracked crown, or both. Every job starts with a camera-scan inspection and a written price before any work begins - no exceptions, no surprises.

How Olympia Chimney Products Fail - and How We Fix Them

• 300 Series stainless caps: weld-seam separation at the skirt. The 300 Series uses a rolled seam where the vertical skirt meets the horizontal lid, and after five to seven Alpharetta summers that seam opens from thermal cycling. Water runs straight down the flue tile, not around it. We replace with a matching Olympia profile or, when the flue configuration allows, upgrade to a Gelco single-piece stamped cap that eliminates the seam entirely.
• 200 Series galvanized caps: base-rust bleeding onto the crown. The 200 Series galvanized shell holds up reasonably well, but the rolled-steel base ring traps moisture against the crown mortar. In Alpharetta’s humid shoulder seasons, that trapped water accelerates spalling - surface flaking that looks cosmetic until the crown loses its slope. We pull the cap, assess crown integrity with a hammer test and camera check of the flue interior, then either coat with HeatShield CrownCoat or rebuild the crown if the rebar’s exposed.
• Multi-flue 400 Series: inadequate overhang for wide chimney profiles. The 400 Series multi-flue cap ships with a standard 1.5-inch overhang, which is fine for a compact chimney in a dry climate. Alpharetta gets driven rain from the southeast, and we’ve seen water bypass the cap entirely on chimneys wider than 36 inches. We spec custom-fabricated caps through our Haven buying network with 3-inch minimum overhangs, or source direct from Olympia when the lead time works.
• Chimney crown: hairline cracking from freeze-thaw in north-facing exposures. Alpharetta doesn’t freeze often, but when it does - particularly in shaded lots off Rucker Road and the Windward side - a saturated crown can crack in a single night. Olympia Chimney crowns are poured concrete, not precast, so they’re site-specific and can’t be swapped like a cap. We map the crack pattern, inject a flexible sealant if it’s under 1/8 inch, or cut and repour if the crack runs to the flue edge.
• Spark arrestor mesh: corrosion clogging on 300 Series with oil-assisted appliances. The 304 stainless mesh on 300 Series caps corrodes faster when the flue carries oil-combustion byproducts, which happens in Alpharetta homes with supplemental oil heaters tied to the same chimney. Clogged mesh backs up draft and deposits acidic condensation on the crown below. We clean or replace the mesh, verify draft with a manometer, and flag the appliance configuration in the written report.

Our Olympia Chimney Chimney Cap & Crown Process

1. 1
   Call and schedule. Live person answers. We book a window, text you when the tech’s en route, and send a named, background-checked technician.
2. 2
   NFPA 211 Level 2 inspection with camera. Corrine Halstead and our crew have worked Alpharetta long enough to know which flue configurations local builders favored in different eras. The camera goes down the flue before we touch the cap or crown. Clause 4 of the Haven Standard requires a documented photo record on every job - we’ve done this since 2009.
3. 3
   Written price, written scope, written warranty. Before any work starts, you get the full number. If it’s a cap replacement, we note whether we’re using Olympia OEM, Gelco, or Famco equivalent and why. If it’s crown work, we specify coating versus rebuild. No verbal estimates. No “we’ll see how it goes.”
4. 4
   Repair with proper materials. Caps are fitted with stainless fasteners and high-temp sealant. Crown coatings get two passes of HeatShield CrownCoat with a cure-time interval. Rebuilds use 4,000 PSI concrete with integral waterproofing, troweled to a minimum 2-inch overhang past the chimney face.
5. 5
   Post-repair camera verification and draft test. We run the camera again to confirm no debris entered the flue during the work, then check draft with a manometer. The photos, readings, and completed scope go into your documented record.
6. 6
   Cleanup and 365-Day Done Right Promise activation. Stamped on every job. If it’s not done right, we make it right.
