Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

How Gelco Products Fail - and How We Fix Them
Gelco builds masonry and flue components that show up in a lot of older Annapolis chimneys, especially homes built between the 1970s and early 2000s. Here’s what we see most on Gelco jobs around the county:
- Gelco clay flue liner cracking from freeze-thaw stress. Annapolis winters don’t stay cold, they cycle. Water gets into hairline cracks, freezes overnight, thaws by noon. Repeat that a few hundred times and a Gelco liner splits. We repair this with a HeatShield resurfacing where the liner is sound, or we pull and replace with a DuraFlex stainless liner if it’s too far gone.
- Spalling brick on older Gelco crown assemblies. The crown is where Gelco systems most often fail in Annapolis. If the crown wasn’t poured with enough overhang, water runs down the face of the brick. The brick face pops off in sheets. We rebuild the crown, then waterproof the masonry with a siloxane sealer that lets the brick breathe.
- Mortar joint washout from salt air. Homes close to the Severn or the Bay get salt-laden air that eats soft mortar. Gelco installations from the 80s and 90s often used mortar mixes that break down faster than the brick. We repoint with a matching mortar and tool the joints tight.
- Gelco chase top rust-through on prefabricated units. If you have a Gelco chase cover that’s rusted through, the water gets into the firebox space and rots framing. We replace the chase top and usually add a Gelco cap that actually sheds water.
- Flashing failure where the Gelco flue meets the roof line. Annapolis rooflines with steep pitches put a lot of stress on flashing. Once the flashing lifts, water tracks down the outside of the Gelco flue and into the masonry. We re-flash with proper step flashing and a sealed counter-flashing so water goes where it should.
Our Gelco Chimney Repair Process
Here’s what happens when you call Top Hat Chimney about a Gelco chimney problem in Annapolis:
- 1
You call, a person answers. You’ll describe what you’re seeing. We’ll ask a few questions and give you an arrival window, not an all-day guess. There’s no trip charge inside our service county.
- 2
Wendell or a background-checked crew member shows up. Someone in uniform walks the property, checks the flue, the crown, the flashing, and the firebox. We take photos of everything with the camera, including the inside of the flue.
- 3
You see the evidence. We show you the camera footage and give you a plain-English verdict. If it doesn’t need doing, Wendell will tell you that too. No scare-pitch, no mystery damage.
- 4
Parts decision is made with you. For Gelco-specific components, we use OEM where warranty matters and the part is available. Where an aftermarket part from DuraFlex or Olympia performs just as well and costs less, we say so, and we tell you why.
- 5
We do the repair and show you the result. After the work is done, we run the camera again, walk you through what changed, and you sign off knowing exactly what you paid for.
- 6
You get the 90-Day Done Right Promise in writing. If something isn’t right, one call brings us back at no additional cost. That’s stamped on every single Gelco job we do.
What Gelco Chimney Repair Costs in Annapolis
Gelco chimney repair in Annapolis runs a wide range because the job can be a patch or a rebuild. Here’s what we typically see:
| Repair Type | Typical Cost in Annapolis |
|---|---|
| Mortar repointing (small area) | $350 – $900 |
| Spalling brick repair (partial face) | $500 – $1,400 |
| Crown rebuild with waterproofing | $850 – $2,200 |
| Flashing replacement | $450 – $1,200 |
| Full chimney rebuild (above roofline) | $3,000 – $8,000+ |
What moves the price is access. If your Annapolis roofline is steep or the chimney is three stories up, the job costs more because it takes longer and needs more safety setup. If the Gelco flue liner itself is shot, that adds a liner install on top of the masonry work. Every estimate is free and the number we give you is the number you pay. Call (240) 851-3653 for a fixed quote.
Why Annapolis Homeowners Call Top Hat Chimney for Gelco Work
We’ve been doing this since 1999. Wendell Pike started Top Hat Chimney the same year, and he’s been inside more Annapolis flues than he can count, including a good stretch of the Historic District where the fireplaces are old enough to have opinions. He learned the trade hands-on after a vocational program at Southwestern College, then put in real years of work before he stopped counting how many flues he’d swept.
When you hire us for Gelco repair, you get a locally owned, owner-operated company with a published address and license number. You get a live person on the phone around the clock, and it may well be Wendell picking up. You get the 90-Day Done Right Promise on every job. And if your Gelco system needs something we don’t install, we’ll tell you that too. We also service DuraFlex liners and HeatShield systems, so if your repair turns into a liner replacement, we can handle that as well.
Permanent standing offers apply to Gelco work just like everything else: $40 off any repair over $200, free second opinion on any competing written estimate, and 10% off always for seniors and veterans.
FAQs
No, not if the repair is done properly and the existing components still meet the installation requirements. As an independent Gelco service provider, we’re careful about which repairs touch warranty-covered parts and which don’t. We’ll flag anything that could affect a warranty claim before we touch it. Call (240) 851-3653 and we’ll walk you through what applies to your system.
Most Gelco-specific replacement parts for chimneys from the 1980s and 90s are still available, though some discontinued components take a week or two to source. Where a part is no longer made, we have direct-fit aftermarket options from DuraFlex and Olympia that we’ve used for years. We’ll show you the difference and let you decide.
Repair if the brick is structurally sound and the flue liner is intact or resurfaceable. Replace if the masonry has shifted, the liner is gone, or water has been getting in long enough to rot the framing. The camera footage will settle it quickly. Call (240) 851-3653 and we’ll give you a straight answer with the evidence.
Usually within a week or two, depending on the season and what the job involves. If it’s a safety issue, we’ll make room sooner. When you call, you’ll talk to a live person who can look at the schedule and tell you straight what’s possible. No trip charge inside the county for the estimate.
Water keeps getting in. The freeze-thaw cycle keeps working. The brick keeps spalling. And if the flue liner is involved, you’re now looking at a chimney fire risk or carbon monoxide leaking into the house. Your flue doesn’t care how the fire looks. It cares how it breathes. A $500 repointing job this year beats a $6,000 rebuild in five years. Call (240) 851-3653 for an exact quote on your Gelco chimney.
