How Gelco Products Fail – and How We Fix Them

• Gelco cast-in-place flue liners cracking at the mortar joints. We see this most often in older Long Beach homes where the original Gelco liner was poured decades ago and seasonal thermal cycling has done its work. The symptom is usually a thin white efflorescence streak on the exterior chimney face after rain. The fix is a HeatShield resurfacing or a DuraFlex stainless liner dropped down the existing flue, depending on what the camera inspection shows.
• Gelco chimney crowns spalling at the edges. Long Beach’s salt air accelerates freeze-thaw damage on exposed concrete crowns, and Gelco crowns from the 1980s and 1990s were often poured without proper drip-edge overhang. The fix is a crown rebuild with a proper bond break and expansion joint, sealed with a siloxane-based waterproofing compound rated for coastal exposure.
• Gelco refractory panels in prefabricated fireboxes cracking behind the grate. This is a heat-cycle failure, not a chimney sweep problem. Once a panel hairline-cracks, combustion heat reaches the metal firebox shell and things degrade fast. We replace panels with OEM-spec refractory material, never with generic firebrick cut to fit.
• Gelco chimney caps and spark arrestors rusting at the mesh-to-frame weld. Salt air again. The mesh is usually the first thing to go, and once it starts tearing, you’re not just losing spark protection – squirrels and birds get in. We replace with aftermarket stainless caps that outlast the originals, installed to the same mounting pattern.
• Gelco dampers seizing at the hinge or cable. Top-sealing Gelco dampers on older Long Beach homes often bind because the cable housing corrodes internally. Sometimes it’s a simple cable replacement; sometimes the whole damper needs swapped. We’ll tell you which one it is before we do anything, with a photo from the interior.

Our Gelco Chimney Repair Process

Every Gelco job at Flint Chimney Co Long Beach follows the same discipline, which is the whole reason our guarantee holds up. Here’s how it runs:

1. 1
   Call and schedule. A live person answers (562) 317-7262, takes the address, and gives you a firm arrival window.
2. 2
   On-site inspection. We run a camera through the entire flue from top to bottom and photograph everything visible from the roof and at the firebox. You get the full report before anyone touches a trowel.
3. 3
   Written price. We hand you a line-item quote covering materials, labor, access equipment if needed, and cleanup. That number is final unless we uncover something the camera couldn’t see – and we re-quote before proceeding.
4. 4
   The work. Repoint, rebuild, waterproof, or reline using specified materials – Gelco components where original, or DuraFlex and HeatShield where a legitimate upgrade is called for.
5. 5
   Post-repair test and photos. We verify the repair with the camera again so you’re not taking our word for it. You get before-and-after photos for your records.
6. 6
   365-Day Done Right Promise. Every Gelco repair carries our written guarantee, valid for one full year from the service date. If a covered repair fails, we return free – no charge, no argument.

What Gelco Chimney Repair Costs in Long Beach

Here’s what we charge for the most common Gelco repairs in Long Beach, based on the work we’ve done across the city:

• Mortar repointing around Gelco flue tile: $450 – $900
• Tuckpointing a Gelco brick chimney face: $18 – $32 per square foot
• Chimney crown rebuild (standard residential, one flue): $650 – $1,150
• Flashing repair at the roofline: $350 – $800
• Chimney waterproofing (full exterior treatment): $500 – $950
• Partial chimney rebuild (above roofline, typical homes): $2,800 – $6,500

What moves the price most is access. A two-story Long Beach roof with a steep pitch costs more than a single-story ranch in Los Altos. A chimney that’s already been repointed once may need deeper grinding, which adds labor. Call (562) 317-7262 and we’ll send a tech out to quote it exactly – the estimate is free and the number you approve is the number you pay.

Hank Delano grew up in Los Angeles and learned the trade at LA Trade-Tech before spending close to two decades working chimneys across Southern California.

Our techs know which Gelco parts still hold up and which ones are worth replacing with DuraFlex or HeatShield alternatives. Every job gets a written price before work starts, and every repair carries the 365-Day Done Right Promise. Clean flue, honest report – that’s the whole job. We’re an independent service provider, not a Gelco-authorized shop, so you get straight answers about what actually needs fixing and what can ride another season.
