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.

AfterGelco Chimney Cap & Crown in Washington: What to Know First
Gelco chimney cap and crown work in Washington typically runs $385 to $1,650 depending on whether we’re replacing a cap, rebuilding a spalled crown, or fabricating a custom multi-flue lid. Most Gelco cap replacements are done in a single visit because we stock common sizes, while crown repairs need a second trip to cure. Our price is written before we start, not after a tech is in your fireplace. This page is for homeowners in Washington, DC with a Gelco cap or crown installed in the last ten to fifteen years who want to know what actually fails, what it costs to fix, and whether the repair can wait. Call (240) 621-1264 and a live person answers.
How Gelco Products Fail - and How We Fix Them
- Gelco Stainless Multi-Flue Caps: Rust Streaking at the Mesh Seam. The crimped joint where the expanded metal mesh meets the lid shows rust first on Gelco caps installed before 2018. It’s not a manufacturing defect. It’s where Washington’s wet winters hold moisture against two dissimilar metals. We replace the cap with a seam-sealed unit and note the warranty date on the written scope.
- Gelco Terracotta-Look Caps: Freeze-Thaw Spalling. Washington row houses with Gelco decorative terracotta-style caps see crown spalling faster than homes with plain lids. Rainwater pools on the wide flat section, freezes, and pops the surface. We rebuild the crown with a sloped top and crown coat that sheds water toward the gutter line.
- Gelco Standard Single-Flue Caps: Loose Mounting Band After Wind. Gelco’s pressure-fit mounting band holds well until repeated gusts work it half an inch loose. You’ll hear a metal rattle on windy nights. We re-seat with mechanical fasteners and a high-temp silicone bead, then pull on it before we leave the roof.
- Gelco Cap Screens: Squirrel-Chewed Corners. The corner welds on older Gelco screen caps can be pried open by a determined squirrel. We see this constantly in Capitol Hill and Petworth lofts. We replace with a welded-corner aftermarket screen sized to the exact flue tile, not a friction-fit universal.
- Gelco Crown Coat Products: Under-Cured Edges. Gelco’s brush-on crown coat works well when applied to a clean, dry crown at the right temperature. Washington’s spring humidity can leave edges under-cured and crumbly within a season. We strip, re-prime, and coat on a dry day, then return the next day to check the cure before the written warranty starts.
Our Gelco Chimney Cap & Crown Process
- 1
Call and name the product. You call, a live person picks up, and we ask what’s on the roof: Gelco cap, terracotta-look, multi-flue, or unknown. Unknown is fine. We’ll find out when we get up there.
- 2
Camera inspection before anything else. We run the camera down the flue and check the crown from the roof. That’s a Level 2 inspection per NFPA 211, and it’s included on every visit. Photos become part of your record.
- 3
Written scope with a decision point. If the Gelco cap has years left, we say so and write that. If it’s done, we show you why on the spot and quote a replacement or repair in writing. You decide with the photo in front of you.
- 4
Parts decision: OEM or trusted aftermarket. Some Gelco sizes are still available. When they aren’t, or when an aftermarket part outperforms the original, we say that plainly and price both when it helps you.
- 5
Repair or replacement, done clean. We do the work, test the fit, and photograph the finished cap or crown from three angles. Those photos go into your job file.
- 6
Written warranty and a follow-up photo record. You get a documented record under Haven Standard Clause 4, a written warranty, and a text when the tech is on the way next time. If it’s not done right within 365 days, we make it right.

FAQs
Replacing a failed Gelco cap with a trusted aftermarket part does not void a homeowner’s warranty on other components in most cases, and if the original cap is already out of warranty, there’s nothing to void. We tell you whether a Gelco-branded replacement or a better-fitting aftermarket cap is the right call, with the reasoning written down.
Most common Gelco cap sizes are on our trucks or available same week. Custom caps take seven to ten days because they’re measured, fabricated, and powder-coated to your flue tile. We’ll tell you which one your job is before you decide.
If the crown is cracked but the concrete is still solid, a Gelco crown coat will buy you five to eight years. If it’s spalled to the point where you can see loose aggregate and the slope is gone, coating it is throwing good money at a bad base. We’ll show you a photo of your actual crown and let you decide.
A failed Gelco cap lets rain, birds, and squirrels into the flue. In Washington, that means water mixing with creosote to make an acidic slurry that eats at the liner joint. The repair cost doesn’t stay the same; it compounds. If the cap is loose but the screen is intact, you have a few months. If the screen is torn, call and we’ll fit you in.
Yes. We service caps from Olympia Chimney, Famco, Copperfield, and others, and we stock backup liners from DuraFlex and HeatShield when a cap failure has done damage further down the flue.
