Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterGelco Chimney Cap & Crown in Chesapeake: What to Know First
We provide independent Gelco chimney cap and crown service throughout Chesapeake, from Great Bridge to Hickory, with most Gelco cap replacements and crown repairs completed in a single visit and priced upfront before we start. As an independent Gelco service provider, we stock common Gelco parts and compatible professional-grade alternatives, so you’re not waiting on factory shipping while water gets into your flue. Typical Gelco cap or crown jobs in Chesapeake run $280-$750 depending on whether we’re replacing a standard single-flue cap, coating a cracked crown, or fabricating a custom multi-flue solution for an oversized chimney. If you own a Gelco product and suspect the cap is rusting through, the crown is spalling, or you’re seeing water stains on the ceiling near your fireplace, call us at (757) 590-6579. We’ll send a technician with a camera, show you exactly what’s happening, and give you a number that won’t change.
How Gelco Products Fail - and How We Fix Them
- Gelco Stainless Single-Flue Caps (Model 8″-13″ round) - The 304-grade mesh on these caps holds up well in Chesapeake’s salt air, but we’ve found the spot-welded corner seams on units manufactured before 2019 tend to crack after seven to ten years of thermal cycling. Once the seam opens, driving rain enters at an angle and pools on the smoke shelf. We remove the failed cap, inspect the flue tile for spalling, and install either an OEM Gelco replacement or a heavier-gauge Copperfield equivalent with fully welded seams and a lifetime warranty.
- Gelco Multi-Flue Caps (Model M-8 through M-16 series) - These ship with galvanized steel mounting brackets that corrode faster than the stainless cap body in Chesapeake’s humid summers, especially on homes within a few miles of the Elizabeth River or the Intracoastal Waterway. The bracket fails silently; the cap lifts in a nor’easter and lands in your yard, or worse, blocks the flue. We replace with 316 stainless brackets and add counter-flashing where the crown condition allows, so the next cap stays put.
- Gelco Draft-Increasing Caps (Vacu-Stack and WindBeater series) - The spinning turbine on Vacu-Stack caps seizes when grease and creosote bake onto the bearing housing, common in Chesapeake homes that burn seasoned oak six months a year. Homeowners smell smoke on startup or hear the turbine grinding. We disassemble, clean the bearing race with a solvent that won’t degrade the factory seal, and re-lubricate with high-temp grease. If the housing is warped from overheating, we source a replacement rotor assembly rather than selling you a whole new cap.
- Gelco Concrete Crowns (poured overlays and pre-formed systems) - Gelco’s crown coating products, when applied over original builder-grade crowns, trap moisture if the substrate wasn’t properly dried, a mistake we see often in the 1970s and 1980s ranch homes throughout Greenbrier and Western Branch. The coating delaminates in sheets after two to three winters. We grind off the failed coating, let the concrete breathe with a fan and heat gun if needed, then apply HeatShield CrownSeal in two thin passes so moisture escapes upward and the bond holds.
- Gelco Chimney Cap Screens (universal fit and model-specific) - The 3/4″ mesh on older Gelco caps meets code but clogs with catalpa and pine pollen in Chesapeake’s heavy spring seasons, choking draft and pushing smoke into the house. We’ve pulled screens caked an inch thick by early May. We clean the existing screen where the frame is sound, or upgrade to a 5/8″ mesh with a steeper pitch that sheds debris, on a cap body that fits your Gelco mounting points exactly.
Our Gelco Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask for your Gelco model number if you have it, the age of the cap or crown, and what you’re seeing. We book a window and send a confirmation.
- 2
Level-2 camera inspection on arrival. Our technician photographs the cap or crown from the roof, runs a camera down the flue to check for water damage below, and shows you the images on a tablet. You get a plain-English verdict: what’s failed, why it failed, and what happens if you wait.
- 3
Parts decision with options. If your Gelco part is still manufactured, we quote OEM. If it’s discontinued or the OEM lead time exceeds two weeks, we quote a compatible professional-grade alternative from Copperfield or Famco, explaining the trade-off in gauge, warranty, and finish. You choose before we start.
- 4
The repair. For caps, we remove the old unit, inspect and re-bed the crown surface, install the replacement with new fasteners and sealant rated to 1,200°F. For crowns, we grind, patch, coat, or pour, depending on what the inspection revealed. Most Gelco cap and crown jobs finish in two to four hours.
- 5
Post-repair test and documentation. We run a smoke test or draft gauge check to confirm proper draw, photograph the completed work, and email you the report with before-and-after images and your invoice.
- 6
The 90-Day Done Right Promise. If anything about the cap or crown isn’t right, we come back. In writing, no arguing.

Why Chesapeake Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been working on Chesapeake chimneys since before the city incorporated, and Russell Haines and our crew know the older brick construction in neighborhoods like Great Bridge and South Norfolk where Gelco caps were popular retrofits in the 1990s. We carry Gelco-compatible parts, but we’re not locked to any single brand. When a Gelco line is back-ordered or discontinued, we pivot to DuraFlex, HeatShield, or Copperfield equivalents that meet or exceed the original spec. Our technicians are background-checked, uniformed, and trained to document every job with photos you can see and a verdict you can understand. The 90-Day Done Right Promise means if the crown coating cracks or the cap seal fails, we fix it. In writing, no arguing. If the chimney’s right, you won’t hear from me until next season. That’s the point.
FAQs
No - Gelco’s limited lifetime warranty on stainless caps covers manufacturing defects, not installation or weather damage, so independent repair does not affect it. We keep photos of the original part’s condition in case you need to file a factory claim later. If you want to explore warranty replacement first, we can document the failure and you can contact Gelco directly; if they decline, we’ll still be here to install the replacement. Call (757) 590-6579 and we’ll walk you through both paths.
A properly installed Gelco 304 stainless cap typically lasts 15 to 20 years in Chesapeake, but the salt air and high humidity near the river and bay can shorten that to 10 to 12 years if the crown underneath wasn’t sealed or if the mounting hardware was galvanized rather than stainless. We see the shortest lifespan on homes south of Battlefield Boulevard where the wind-driven rain is heaviest. When we replace yours, we use all-stainless fasteners and inspect the crown condition so the next cap outlasts the first.
We can match most discontinued Gelco profiles with custom-fabricated Copperfield or Famco caps that use the same mounting points and flue clearance specs. For the rare profile we can’t source, we fabricate a stainless lid from measurements on site. You do not need a full chimney rebuild unless the crown and flue tile are also failing, and we’ll show you camera evidence if that’s the case. Call (757) 590-6579 for a free look.
Repair with a professional coating like HeatShield CrownSeal is appropriate when the crown has surface cracks, minor spalling, or thin spots but the structural concrete is sound. We replace when cracks penetrate through to the flue, when the crown has pulled away from the flue tile creating a gap, or when more than 30 percent of the surface is lost. Our camera inspection and tap test tell us which category you’re in, and we explain it before you commit.
We book most Gelco cap and crown inspections within three to five business days, and we keep common Gelco and compatible replacement caps in stock for same-visit replacement if the inspection confirms it’s needed. Crown coating and repair jobs sometimes require a dry weather window, which in Chesapeake’s spring can mean a short wait, but we’ll tell you honestly when we can start and we’ll be there when we say. Call (757) 590-6579 to get on the schedule.
