Gelco Chimney Liner & Rebuild in Annapolis: What to Know First

We service Gelco chimney liners in Annapolis, and most liner replacements or rebuilds take one to two days once we’ve put eyes on the flue. As an independent Gelco service provider, we’re not affiliated with the manufacturer, which means we’ll tell you straight whether that liner can be repaired or needs to come out. Call (240) 851-3653 and you’ll get an honest read before any work is scheduled. This page is for Gelco owners in Annapolis who want to know what’s actually wrong, what it costs, and whether it’s urgent.

• Most Gelco liner replacements run $1,800 to $4,200 in this market, depending on flue size and access.
• Every job carries our 90-Day Done Right Promise in writing.

How Gelco Products Fail - and How We Fix Them

We’ve pulled plenty of Gelco liners out of Annapolis chimneys, and the failure patterns are consistent. Here’s what we actually find:

• Gelco Stainless Steel Liners (single-wall flex): The most common issue in Annapolis is corrosion pitting along the seam welds, usually from acidic flue gas mixing with coastal humidity. It starts as a pinprick and grows. We don’t caulk these; if the pitting is in the bottom third, we cut and splice a new section. If it’s throughout, the liner gets replaced.
• Gelco Insulated Flex Liner Kits: We see failure at the top connector where the liner meets the rain cap, especially on chimneys without a proper chase cover. Annapolis rain runs inside and puddles in the insulation wrap. We replace the connector, test the cap gasket, and if the insulation is saturated, the whole liner gets swapped.
• Gelco Rigid Liner Sections: The weak point is the locking seam. When a fire burns hot (common with hardwoods stacked near the Bay), the seam expands and pops. We weld reinforcement collars or replace the section. This is not a DIY caulk job; a popped seam is a carbon monoxide path.
• Gelco Liner-to-Flue Fit Issues: We’ve pulled Gelco liners that were undersized for the appliance. A water heater venting into a 6-inch liner when it needs 4 inches creates condensation and premature rust inside the liner. We correct the sizing when we rebuild; a loose fit is a draft killer and a rust starter.
• Gelco Liner Tears During Installation (previous installer error): More times than we can count, a liner in Annapolis comes out with a longitudinal tear from being yanked through an offset flue. Gelco’s single-wall flex is sturdy but not indestructible. We pull the old liner, measure the true flue path, and if the offset is sharp, we upgrade to a heavier-gauge liner rather than repeat the same mistake.

Our Gelco Chimney Liner & Rebuild Process

Here’s how a Gelco job runs with us, start to finish:

1. 1
   You call, a live person answers. Could be me, Wendell Pike. We book a time, give you a real arrival window. No call center, no “sometime between Tuesday and Thursday.”
2. 2
   We camera the flue. You see the footage. If the liner is pitted, torn, or undersized, we show you exactly where and why. If it doesn’t need doing, I’ll tell you that too.
3. 3
   Parts decision on the spot. For Gelco, we evaluate whether an OEM section or a quality aftermarket equivalent makes sense. Some Gelco OEM parts are backordered six weeks; we’ll tell you if an aftermarket Duralloy or equivalent will hold the same or better, with no warranty conflict on the repair.
4. 4
   The rebuild. We pull the old liner, clean the flue path, and install the new liner with the right connectors, top plate, and rain cap. For a full chimney rebuild, we address the masonry structure, crown, and liner as one system, not three separate jobs.
5. 5
   We test the draw and check for leaks. Then I walk you through the camera footage of the finished job so you can see what’s behind the wall.
6. 6
   You get the 90-Day Done Right Promise in writing. If it’s not right, one call brings us back. That’s been true since 1999.
