How Gelco Products Fail - and How We Fix Them

Gelco builds solid chimney components, but they’re not immune to Leesburg’s freeze-thaw cycles and humid summers. Here’s what we see in the field, on real Gelco installations across Leesburg homes.

• Gelco galvanized steel chase covers rust through at the seams. The covers do their job for years, then rust starts where the screws penetrate and the folded corners hold water. Once a chase cover fails, water runs down the inside of the chase and into the flue opening. We replace with stainless steel, re-seal the flue termination, and document the old cover’s condition so the record’s clear.
• Mortar joints on Gelco masonry chases crack and spall. Lee sburg’s winter temperature swings - overnight lows in the 20s, daytime highs above freezing - force water into hairline cracks, where it expands and breaks the joint. We see this most on Gelco chases built with modular brick facing over a framed chase. Our fix is full repointing with Type N mortar, then waterproofing.
• Gelco multi-flue caps loosen at the anchor points. When a cap is installed over two or three flues, wind load and thermal expansion work the anchors loose over time. A loose cap shifts, water gets between the cap and the flue tile, and you get efflorescence on the brick below. We reset the cap with new anchors and silicone sealant rated for high-temperature exposure.
• Gelco direct-vent chase terminations leak where the pipe meets the cap plate. On gas fireplace chases, the termination collar and storm collar are the first things to go. The silicone fails, water follows the pipe down, and you get water staining on the ceiling below the firebox. We reseal and, if the collar’s too far gone, replace with an aftermarket stainless collar that doesn’t care about Gelco’s OEM number.
• Prefab Gelco fireplaces - not repairable, but the chase around them is. Gelco’s prefab firebox units are sealed appliances. When one fails, we don’t open it up. But the chase, the cap, the flashing, and the termination assembly around it are all repairable, and that’s where most of the leaks actually are.

Our Gelco Chimney Repair Process

Here’s what a Gelco repair job looks like when you call Level Two Chimney Leesburg.

1. 1
   Call and schedule. A live person answers - 24/7, not a voicemail or a form. You’ll get a named technician and a two-hour arrival window, plus a text when they’re en route.
2. 2
   Level 2 camera inspection. Our tech runs a camera down the flue and up into the chase on every repair visit, not just on inspections. Clause 4 of the Haven Standard requires a photo record on every job, and on a Gelco repair that’s how we know exactly what’s leaking before we quote it.
3. 3
   Written price and scope. You get a written price, written scope of work, and a written warranty before anything starts. No “we’ll see once we open it up.” If we find something unexpected mid-repair, we stop, show you the camera footage, and quote the change in writing.
4. 4
   The repair. For masonry, we use Type N mortar matched to the existing joint profile. For chase covers and caps, we’re using stainless aftermarket parts that outlast the originals. For waterproofing, we’re spraying Siloxane-based sealer, not a cheap film.
5. 5
   Test and re-inspect. After the repair, the flue gets re-scanned and the repair area re-photographed. You see the before and after, side by side.
6. 6
   Documentation and guarantee. You walk away with a photo record, a written warranty, and the 365-Day Done Right Promise: if it’s not done right, we make it right.

What Gelco Chimney Repair Costs in Leesburg

Most Gelco repairs in Leesburg fall into these ranges. These are our actual price bands, not bait numbers.

• Mortar repointing (tuckpointing) on a Gelco chase: $350-$900 depending on how many joint feet and how much needs cutting out.
• Chase cover replacement (stainless steel): $850-$1,600 depending on chase size and if it needs a custom fabrication.
• Flashing repair on a Gelco masonry chase: $400-$1,200 depending on how much of the step and counter flashing is salvageable.
• Spalling brick repair: $500-$2,000 depending on how many brick faces need replacement and whether we’re color-matching a custom blend.
• Full chimney or chase rebuilding: $3,500-$12,000+ depending on height, access, and whether the flue liner is reusable. We’ll quote this only after a camera scan and we’ll tell you if it can safely wait.

What moves the price: roof pitch, scaffolding requirements, whether the interior flue is still sound, and how much the previous painter or roofer sealed over the problem. We’ll give you a free exact quote on any of this - call (571) 601-3174.
