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.
Gelco Chimney Cap & Crown in Annapolis: What to Know First
We repair, replace, and rebuild Gelco chimney caps and crowns in Annapolis, usually within a week of your call. Most Gelco cap and crown jobs run between $185 and $1,400 depending on whether it’s a simple cap swap, a crown recoat, or a full multi-flue rebuild. We’re an independent Gelco service provider, not a factory shop, which means we call it straight: if your cap has five more years in it, we’ll tell you and leave. If you own a Gelco cap or crown anywhere in the Annapolis area, call (240) 851-3653 and Wendell Pike will talk you through what you’re seeing before anyone sets foot on your property.

How Gelco Products Fail - and How We Fix Them
Gelco makes a solid cap, but every brand has its patterns. After 25-plus years of pulling these off chimneys around Annapolis, we know exactly where Gelco parts give out and what that failure looks like from the roof or through a camera lens:
- Gelco single-flue cap screen corrosion at the rivet line. The standard Gelco galvanized mesh cap holds up well for the first several years, but Annapolis gets a lot of salt air and wet freeze-thaw cycles. The stainless rivets hold; the galvanized mesh around them doesn’t. You’ll see a rusty ring forming around each rivet head long before the screen actually tears. We replace the screen with true stainless mesh, not a new galvanized sheet that will do the same thing in six years.
- Gelco multi-flue cap leg brackets pulling loose on brick-and-stone spreads. The factory leg brackets are decent, but on older Annapolis chimneys with uneven crown surfaces, the brackets don’t seat flat. That leaves a gap where wind gets under the cap and works the bolts loose over two or three seasons. We shim and bed the legs properly on the crown surface, and we check the bolt torque on every Gelco multi-flue we service, whether it was our install or somebody else’s.
- Crown spalling under a Gelco cap that’s too tight for the flue tile. A cap that fits too snugly traps moisture against the crown and the flue tile edge. In Annapolis, where we get hard winter rain followed by freezes, that trapped water is what peels the surface off a crown in chunks. We size the replacement cap to the flue tile, not just to the old cap, and we recoat the crown at the same time if it’s needed, which is the step most outfits skip.
- Gelco top-mount damper cap hinge seizing after a few winters. Homeowners don’t always remember that the top-mount damper is also a cap. The hinge pin on these gets a film of creosote, then rain, then rust, and then the cable has to fight the hinge. That’s how cables snap. We clean and lube the hinge assembly as part of any Gelco top-mount damper service, and we can usually free up a stiff one without replacing the whole unit.
- Aftermarket Gelco-style caps that don’t match the original crown footprint. We see a fair number of cheap knockoff “universal” caps on Annapolis chimneys where a homeowner or a handyman tried to save money. The metal is thinner, the screens blow out, and the footprint never matches the crown. By the time they call us, the crown has usually been rained on for two winters. We don’t put those back on. We’ll match the proper Gelco footprint or step you into a quality aftermarket equivalent only when OEM wait times get unreasonable.
Our Gelco Chimney Cap & Crown Process
- 1
You call. A live person answers. You describe what you see: a wobbly cap, a rusty screen, a crown that’s flaking, water staining around the fireplace. Wendell may ask you to text a photo.
- 2
We look at it. We get on the roof and inspect the cap, crown, and flue tile in person. If something looks off inside, we run the camera up the flue so you can see it on video.
- 3
We decide OEM vs. aftermarket with you. For a straight Gelco cap replacement, OEM is usually available and delays are short. For older or odd-sized Gelco caps, we talk through aftermarket options that match the footprint. You always know the price before we order anything.
- 4
The repair or replacement. New cap goes on, properly bedded and secured. Crown work gets a surface prep, a recoat if it’s that stage, or a full rebuild if it’s beyond a coat. We don’t do half a crown job.
- 5
We test and document. We check the fit, the draft, and the seal. We show you the after-photos, same angles as the before-photos, so you can see what your money bought.
- 6
You get the 90-Day Done Right Promise in writing. If any part of our Gelco cap or crown work isn’t right, one call brings Wendell back. No invoice, no argue.
What Gelco Chimney Cap & Crown Costs in Annapolis
Here’s where honest numbers live. A standard Gelco galvanized single-flue cap replacement runs $185 to $325, installed. A stainless Gelco multi-flue cap for a typical Annapolis two- or three-flue chimney runs $450 to $850 depending on footprint and leg style. A crown recoat falls between $325 and $550. A full crown rebuild, which means removing the old crown and pouring new, lands between $900 and $1,400. What moves the price is roof access, flue count, and whether the crown is worth saving or needs to be pulled. We quote a flat number on the phone for standard jobs, and we honor it. Call (240) 851-3653 and we’ll give you a real price, free, before anything gets scheduled.
Why Annapolis Homeowners Call Top Hat Chimney for Gelco Work
Partly it’s because we’ve been doing this since 1999, which means we remember when Gelco caps first started showing up on rooftops around here. Partly it’s because Wendell and his crew work on the other brands too: DuraFlex liners, HeatShield repair. When we tell you your Gelco cap is fine but your flue liner has a problem, that’s not an upsell. It’s the truth, and we have the camera footage to prove it. The promise is simple: if the work isn’t done right, one call brings us back within 90 days. No charge, no fine print, every job, in writing. Ask anyone on your street. In Annapolis, knowing the name of the person who works on your house still means something.
FAQs
No. A cap replacement performed by an independent service provider does not void any Gelco factory warranty on the chimney or fireplace system, provided the replacement cap fits the flue tile correctly. We document every install with photos and measurements, so if a warranty question ever comes up, you have records to back it. That said, if your chimney is still under a builder’s or installer’s warranty, call us before you let anyone else touch it. We’ll tell you whether that warranty is even relevant to what’s failing.
Both. We order Gelco OEM caps and components when they’re available and the lead time works. For older Gelco models that the factory no longer stocks, or when a homeowner wants to avoid a multi-week wait, we recommend specific aftermarket caps that match the flue footprint and hold up to Annapolis weather. The metal gauge and stainless quality are what matter, not the logo. We’ll show you both options and the price on each before you decide.
For a cap replacement, usually within seven to ten days of your call, often sooner depending on parts and access. Crown rebuilds take a little longer since the material has to cure, and we won’t rush that, especially in cold or wet weather. If you have active water coming into the fireplace, tell us that on the phone and Wendell will try to move your job up. Call (240) 851-3653 and we’ll give you a straight answer on timing.
Usually yes, if the crown is already spalling or cracked and the cap is coming off anyway. Doing both at once means one trip, one set of roof work, and a cap that seals properly against a fresh crown surface. It also avoids a second labor charge later. But if your crown is solid and just dirty, we’ll clean it and leave it alone. If it doesn’t need doing, I’ll tell you that too. Call us and we’ll come look before you spend a dollar.
