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 & Crown in Silver Spring: What to Know First
We provide independent Olympia Chimney chimney cap & crown service in Silver Spring, with most inspections and repairs completed in a single visit. A standard cap replacement or crown coating runs $280-$650 depending on flue count and access, and we give you the full price before any work starts. We’re not affiliated with Olympia Chimney, but we’ve installed and repaired their caps and crowns across Montgomery County long enough to know which series hold up and which ones need watching after a hard winter. If you own an Olympia Chimney product and suspect water intrusion, rust streaking, or crown cracking, call us at (301) 479-9806 for a free estimate with photos you can see and a plain-English verdict.
How Olympia Chimney Products Fail - and How We Fix Them
- Stainless single-flue caps (SC-series) with screen blowout. The SC-1317 and SC-913 commonly show mesh separation after 3-5 Silver Spring winters. Freeze-thaw cycles around the Capital Beltway corridor accelerate metal fatigue where the screen meets the cap skirt. We replace with an OEM-equivalent 304 stainless cap or step up to a Gelco multi-flue unit if the flue tile condition warrants it.
- Galvanized multi-flue caps (GMC-series) with base rail rust. The GMC-1717 and GMC-1313 use galvanized steel that holds paint poorly once the factory coating chips. We see this most on homes near Sligo Creek where tree drip keeps the cap base damp. Our fix: remove the compromised cap, assess the crown beneath for spalling, and install a powder-coated replacement or a stainless upgrade depending on your budget and chimney height.
- Crown wash failure on Olympia Chimney-equipped flues. Olympia Chimney doesn’t manufacture crown material, but their cap mounting hardware often gets blamed when the real problem is a thin, cracked crown wash underneath. In Woodside Park and the older brick colonials off Georgia Avenue, we’ve pulled caps that were perfectly fine only to find the crown had turned to sand. We repair with CrownCoat or a poured concrete crown, then reinstall or replace the cap.
- Chimney pot and cap combinations (DECO-series) with improper sealing. The DECO-2 and DECO-3 pots are cast with a base flange that needs high-temp silicone and proper counter-flashing. We’ve found builder-installed units in Four Corners with no sealant at all, just gravity holding them down. Water runs straight into the flue gap and rots out the smoke chamber. We reset with proper sealant, add a storm collar where the pot meets the flue, and document the repair with photos.
- Interior-mounted damper-cap combos (TOP-sealing series) with cable seizure. The TOP-1317 and TOP-913 use a stainless cable that runs down the flue to a control handle. After years of creosote buildup, the cable binds or the cap plate won’t seal fully. We disassemble, clean the track and cable, replace worn springs, and test the seal with a smoke pencil. If the frame is warped, we source the correct Olympia Chimney replacement frame rather than forcing an aftermarket part that won’t seat right.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, 24 hours a day. We book a window that works for you, not a four-hour guessing game.
- 2
Level-2 camera inspection. Our technician arrives in uniform, runs a camera up the flue, and photographs the crown, cap, flue tiles, and smoke chamber. You see what we see on the screen. No surprises, no hidden damage.
- 3
Parts decision with options. We identify your Olympia Chimney series, check OEM availability, and quote both factory and quality aftermarket alternatives. You choose. We don’t choose for you.
- 4
The repair. Most cap replacements and crown coatings finish in one visit. Crown rebuilds or multi-flue custom caps may need a return trip with prefabricated materials. Either way, we protect your roof and landscaping, and we clean up after.
- 5
Testing and documentation. We run water over the crown, check cap clearance and draft, and give you photos of the finished work plus a written summary.
- 6
The 90-Day Done Right Promise. If something isn’t right, we come back. In writing. No arguing. That’s the Keystone Standard we’ve kept since 1984.

FAQs
No - proper repair by a qualified technician does not void your warranty, but using non-OEM parts or improper installation methods can. As an independent Olympia Chimney service provider, we use OEM parts when available and document the work so you have a record if a warranty question ever comes up. If you have your original purchase documentation, bring it to the appointment. Call (301) 479-9806 and we’ll walk you through what’s covered.
A well-maintained stainless cap lasts 15-20 years, but galvanized models in our freeze-thaw zone often show rust at 7-10 years. Homes near mature tree canopy, like much of Woodside Park or Takoma Park, see faster deterioration from constant dampness and leaf acid. We inspect cap condition during every sweep and tell you honestly whether this season or next is the right time to replace. Call for a free inspection.
Usually yes for anything made in the last 15 years. Olympia Chimney maintains decent parts availability, though some discontinued series require us to fabricate or source a compatible aftermarket cap. We check stock before your appointment so we don’t waste your time. If a part is backordered, we’ll give you the timeline and a temporary solution if water intrusion is active. Call (301) 479-9806 with your model number.
Coating works for surface cracks and minor spalling with solid structural base. If the crown is cracked through, separated from the brick, or more than 50% deteriorated, coating buys you a year or two at best and wastes your money. We show you the camera footage and explain which category you’re in. No coating goes on without checking the base first. Call for an honest assessment.
We answer live 24 hours a day and schedule as fast as the calendar allows. True emergencies - active water pouring in, cap blown off in a storm - get priority. Most standard cap and crown work books within a few days. We’ll tell you honestly whether a temporary tarp measure makes sense while you wait for a dry day to do the permanent repair. Call (301) 479-9806 and we’ll find you a slot.
