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 Annapolis: What to Know First
We provide independent Gelco chimney cap and crown service in Annapolis, and most jobs are completed in one visit with a written price before any work starts. A standard Gelco cap replacement in Annapolis typically runs $425-$680 installed, while crown repair or coating lands between $350-$950 depending on damage and flue count. This page is for homeowners who own a Gelco cap or crown and want a plain answer about what failed, what it costs, and whether it can wait. Call (443) 274-4231 and a live person answers.
If you bought a home in Annapolis between 2015 and 2025, there’s a fair chance a Gelco cap is sitting on your chimney right now. Contractors in this area installed them heavily during that stretch. We see them on brick ranchers in Hillsmere, capes in Admiral Heights, and a lot of the older wood-burning units along the Eastport waterfront where salt air works on metal year-round. Gelco makes a solid cap. But every brand has failure modes, and Gelco’s happen to be specific, predictable, and usually fixable before they become liner problems.
How Gelco Products Fail - and How We Fix Them
Gelco caps and crowns are built well, but Annapolis weather finds the weak points. Here’s what we actually see when the camera comes back up:
- Gelco Legacy Series cap: wind baffle separation. The Legacy line uses a riveted wind baffle that starts to chatter in coastal wind conditions. Over three or four winters in Annapolis, the rivets loosen and the baffle separates from the hood. The cap still looks fine from the ground. The first sign is usually a faint rattle you can hear on windy nights, or rust staining that appears in a straight line where the baffle once sat. We replace the baffle with heavier-gauge stainless fasteners rather than swapping the whole cap when the hood is still sound. That’s a $90-$140 fix instead of a $500 replacement.
- Gelco Stainless Series: mesh clogging and drafting loss. The Stainless Series ships with a standard 3/4-inch mesh that works until it doesn’t. In Annapolis, cottonwood and sycamore debris load the mesh in a single spring. The cap stops pulling smoke properly and the homeowner assumes the flue needs sweeping. It usually doesn’t. We clear the mesh, and if it recurs, we swap in the 5/8-inch mesh panel Gelco offers for high-debris regions. Half the “drafting problems” we’re called for on Gelco caps in Annapolis are just clogged mesh.
- Gelco crown coating: hairline cracking at the flue collar. This is the one Gelco owners miss. The crown itself is usually fine, but the joint where the flue tile meets the crown opens a hairline crack within a few seasons of thermal cycling. Water gets in, freezes, and spalling starts on the flue tile itself, not the crown. Most companies quote a full crown rebuild when they see this. We often don’t need to. We clean the joint, apply a flexible crown sealant, and document the before and after with the camera. If the crown base is still sound, that’s a $350-$500 repair, not a $1,200 rebuild.
- Multi-flue Gelco caps: uneven rust on the leeward side. On two- and three-flue homes in Annapolis, the flue that faces the Bay gets hammered by salt-laden wind. The other side stays clean. The rust always starts on the windward edge of the leeward flue, which is counterintuitive until you see the pattern on camera. If caught early, we treat the surface and re-coat. If the rust has eaten through, we replace with the Gelco Coastal line, which uses a heavier 24-gauge stainless. It costs about 15% more than standard stock and lasts about twice as long within a mile of the water.
- Gelco Custom Cap: incorrect sizing from the original install. We regularly find custom Gelco caps that were ordered an inch too small for the flue. The installer measured the inside, ordered to that number, and the cap sits too tight, restricting airflow. Or too big, and it rocks in the mortar. Gelco will build to any dimension, which is useful, but somebody has to measure correctly. We re-measure to the outside dimensions of the flue tile, check clearance against NFPA 211, and order the correct size when the original cap can’t be adapted. On Gelco customs, the measurement mistake was made before you bought the house, and you’ve been burning against a restricted flue since closing.
Our Gelco Chimney Cap & Crown Process
We follow the same sequence on every Gelco job in Annapolis, whether it’s a simple cap swap or a full crown rebuild. Clause 4 of the Haven Standard requires a photo record on every job, so you’ll see what we saw.
- 1
Call and schedule. A live person answers at (443) 274-4231, 24 hours a day. You’ll get a named tech assigned and a text when we’re on the way.
- 2
Camera-scan inspection up and down the flue. This is where we identify what actually failed on the Gelco cap or crown. Photos, not guesses.
- 3
Written scope and written price before work starts. We name the exact part, whether it’s OEM Gelco or a quality aftermarket equivalent, and the line-item cost. No verbal estimates. No “we’ll see once we’re up there.” Clause 1 of the Haven Standard.
- 4
The repair or replacement. Background-checked, uniformed technicians do the work. We use Gelco OEM parts when warranty continuity matters, and heavy-gauge aftermarket equivalents when the part is a generic like a mounting bracket and the OEM markup doesn’t buy anything real.
- 5
Photo documentation after the work. You get before and after photos of the cap, crown, and flue. If we coated a crown, photos show the coating thickness and coverage.
- 6
Written warranty, stamped. Every Gelco job carries the 365-Day Done Right Promise. If it’s not done right, we make it right.
BeforeAfterWhat Gelco Chimney Cap & Crown Costs in Annapolis
Here’s what Gelco work actually runs in Annapolis, based on jobs we’ve done since 2009:
| Job | Price Range | What Moves It |
|---|---|---|
| Gelco cap cleaning and mesh clearing | $90-$140 | Flue height, debris load |
| Gelco cap replacement (standard single-flue) | $425-$680 | Cap model, flue size, roof access |
| Gelco Coastal cap (heavier gauge for salt air) | $525-$780 | Proximity to the Bay, flue count |
| Crown repair (crack seal, no rebuild) | $350-$500 | Crack extent, flue tile damage |
| Crown coating (full sealant application) | $600-$950 | Square footage, number of flues |
| Full crown rebuild | $950-$1,400 | Material, flue tile replacement needs |
The wildcard is the height and pitch of your roof. A steep roofline in Murray Hill adds labor time and that moves the number. What doesn’t move it is whether you’re financing or paying cash, or whether you bought the house last year. Same written price either way. Estimates are free. Call (443) 274-4231 for an exact quote on your Gelco cap or crown.
Why Annapolis Homeowners Call Level Two Chimney Annapolis for Gelco Work
We’ve cleaned and inspected more than 38,000 chimneys since 2009, and a good portion of those in Annapolis had Gelco caps on top. That matters because you can’t diagnose a failed Gelco cap from the ground. You need a camera down the flue and eyes on the cap itself, and we’ve been doing camera-scan documentation as standard since 2009, years before insurers started asking for it. Corrine Halstead runs this shop, and she started with a wire brush at a vocational program through LaGuardia Community College before deciding chimneys were worth making a career of. Her crew has seen every Gelco failure mode this page describes, and they’ve also seen how other brands behave when a Gelco part needs a workaround. We stock DuraFlex and HeatShield equivalents too, so if a Gelco cap failure has already damaged the flue liner, we can give you one written price for the whole repair, not three phone calls and three different trucks.
FAQs
Gelco caps carry a limited manufacturer warranty, typically 5 to 10 years depending on the series, but the warranty only covers the part, not the labor to swap it. As an independent Gelco service provider, we don’t process Gelco warranty claims. We can tell you whether your failure is likely covered based on what the camera shows, and if you have the original install paperwork, the replacement part cost may be recoverable from Gelco. But labor is on you, and we’ll write the labor price out before anything is ordered.
About 40% of the Gelco caps we see in Annapolis can be repaired rather than replaced. If the hood is still sound and the failure is a separated baffle, clogged mesh, or loose fasteners, we fix it. If the metal has rusted through or the cap was sized wrong from the original install, replacement makes more sense than a patch. We’ll show you the photos that back up the call either way. Call (443) 274-4231 for an honest read on your specific cap.
Most Gelco cap and crown jobs in Annapolis are scheduled within 5 to 10 days, faster if you’re within a mile of the water and the rust is moving. We don’t promise same-day service, because we don’t do same-day service. The urgency on cap and crown work is seasonal, not hourly. A cracked crown in December is a spring repair. A cracked crown in March is a problem before the next freeze. Call (443) 274-4231 and we’ll give you a straight answer about timing.
Yes, and that’s not scare-selling. An unused chimney is exactly where cap and crown failures do the most damage, because nobody notices them. A chimney nobody has used in four years is rarely in better shape for the rest. Water runs down an uncapped flue, erodes the mortar joints, and by the time you smell it in the house, the liner is already compromised. The camera-scan will show you exactly what’s happening, whether the flue is active or not.
For caps themselves, Gelco OEM is what we order when the cap is still under warranty or the customer wants an exact match. For mounting brackets, bolts, and mesh panels, we carry heavy-gauge aftermarket parts that meet or exceed the Gelco spec and cost less because there’s no brand markup. The camera doesn’t guess. Neither do I. You’ll see the part spec in writing before the job starts, and you can choose.
