Gelco Chimney Cap & Crown Nationwide

Gelco Chimney Cap & Crown in Severna Park: What to Know First

We provide independent Gelco chimney cap and crown service throughout Severna Park, with most inspections and repairs completed in a single visit and upfront pricing agreed before any work begins. A standard Gelco cap replacement runs $280-$520; crown repair or coating typically falls between $340-$780 depending on flue count and access. We’re not here to sell you a full rebuild unless your chimney actually needs one, and we’ll show you the photos to prove it either way.

This page is for Severna Park homeowners who already know they have a Gelco cap or crown and want it fixed by someone who understands the product, not a generalist who orders “whatever fits.” If you’re seeing rust streaks, water in your firebox, or a cap that’s taken flight during a Chesapeake Bay nor’easter, call us at (443) 464-2560. A live person answers, 24 hours a day.

How Gelco Products Fail - and How We Fix Them

• Gelco Multi-Flue caps with the 5/8-inch mesh screen: The welded seam where the screen meets the galvanized frame collects salt-laden condensation from Severna Park’s humid bay summers, accelerating corrosion from the inside out. We see this most often on homes within a mile of the Magothy River or the Severn. Our fix is a full screen replacement with 304 stainless mesh, not a patch job, because once the weld starts weeping rust, the cap is living on borrowed time.
• Gelco Single-Flue caps in the 3/4-inch overhang series: The overhang lip catches wind like a sail. After the March 2018 windstorm, we replaced seventeen of these in the Chartwell and Olde Severna Park neighborhoods alone. We upgrade to a lower-profile Gelco cap or add wind-brace strapping on the new install, depending on your flue height and roof pitch.
• Gelco stainless crowns with the factory bead edge: The bead creates a natural water trap where crown meets brick. In Severna Park’s freeze-thaw cycle, that trapped water expands and spalls the crown edge within four to six years. We grind back the damaged edge, apply a tapered Gelco-compatible crown coat, and extend the drip edge past the brick line so water sheds clean.
• Gelco galvanized caps installed before 2015: Pre-2015 galvanizing was thinner, and the salt air here eats it. The cap looks fine from the ground while the underside turns to lace. We pull it, photograph the underside, and recommend stainless or copper replacement. If the flue tile is still sound, there’s no reason to go beyond the cap.
• Gelco chase covers on prefab chimneys: The factory corner folds are stress points. We’ve found cracks at the folds on at least a dozen Severna Park townhomes, particularly in the Riggs Avenue corridor where the 1980s prefab clusters sit. Water runs straight down the chase and rusts the firebox. We replace with a custom-fabricated Gelco-spec chase cover with reinforced corners and a deeper pan slope.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, day or night. We ask whether you know your Gelco model or just the symptoms, and we book a Level-2 camera inspection with one of our background-checked, uniformed technicians.
2. 2
   Inspect and document. We photograph the cap or crown from the roof, run a camera down the flue to check for water damage below, and record everything. You see the same images we see. Russell Haines reviews every Gelco job personally before we quote.
3. 3
   Quote with parts specified. We tell you whether OEM Gelco parts are available for your series, or whether a quality aftermarket equivalent from our DuraFlex or Copperfield inventory makes more sense for longevity. The price on the estimate is the price on the invoice.
4. 4
   Repair or replace. Most Gelco cap and crown work completes in one visit. We bring common Gelco sizes on the truck. Custom fabrications or chase covers typically need a return trip with the pre-measured piece.
5. 5
   Test and guarantee. We water-test crown repairs, verify cap draw with a smoke pencil, and leave the work area cleaner than we found it. Every job carries our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork, no arguing.

What Gelco Chimney Cap & Crown Costs in Severna Park

These are real Severna Park numbers, not national averages padded for your zip code. A straightforward cap swap on a single-story ranch near Benfield Road costs less than the same cap on a three-story colonial off Robinson Road with a 12/12 pitch. We measure, we price, we stick to it. Call (443) 464-2560 for your exact estimate - estimates are free, and we don’t charge to look.
