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 Installation: The Chester Owner’s Guide
If your Gelco chimney cap has rusted through, lost a lid to a windstorm, or started letting rain straight down the flue, we stock Gelco-compatible caps on the truck and can usually have a new one installed the same week. Installed pricing in Chester for a standard Gelco cap swap runs roughly $225 to $385 depending on flue size and roof access, and the quote we give you on the phone is the number on the invoice. Most Chester homeowners figure it out the hard way: a damp spot on the ceiling near the chimney, water pooling in the firebox after a storm, or a cap that’s simply gone after a nor’easter rolls through.
We’re an independent chimney company, by the way. Not affiliated with Gelco. We install their caps because they hold up better than most of what we’ve pulled off roofs in this county.
Which Gelco Models This Applies To
Gelco makes a handful of cap lines, and the compatibility question trips up more people than it should. The short version: we install the full range of Gelco standard and custom chimney caps, including the stainless steel and copper models sized for masonry flues from 8″ round up to 13″x18″ rectangular. The gotcha most Chester owners run into is mixing up the flue tile size with the cap size. Your chimney’s clay tile might measure 8″x8″ on the outside, but the Gelco cap base has to slip over that tile and anchor to it. That means measuring the outside dimensions of the flue tile, not the hole in the middle. We carry calipers on the truck for exactly that reason.
On the OEM-versus-aftermarket question: for Gelco specifically, we’ve found their own stainless caps are hard to beat for the money. A quality aftermarket cap will do the job in most cases, but the Gelco base flanges and screen mesh are built to a thickness we’ve seen cheap generics fail to match. If your old Gelco cap lasted 15 years, the replacement should too. That’s the standard we hold it to in Chester’s freeze-thaw cycles and summer thunderstorms.
Signs Your Gelco Chimney Cap Installation Is Failing
- Water in the firebox after rain. This usually means the cap’s lid has rusted through or the screen mesh has pulled away from the base, letting water run straight down the flue instead of around it. In Chester, we see this most after March and April storms, when the winter rust has had time to open up seams.
- Rust streaks on the chimney crown. A Gelco cap made of galvanized steel will eventually sacrifice itself to the weather. When the rust runs down onto your crown and stains the brick, the cap’s structural integrity is already gone and the fix is a swap, not a scrub.
- The cap simply isn’t there anymore. High winds along the James River corridor will take an older cap clean off. We’ve found caps in neighbors’ yards more than once in Chester. If yours vanished, the flue is wide open and every squirrel in the county knows it.
- Debris or nesting material inside the flue. A cap with a torn screen will let birds, squirrels, and roof debris into the flue. It’s not a cosmetic problem: nests against a warm flue liner are a fire hazard, plain and simple.
- Draft issues or smoke backing up. A cap that’s partially collapsed or clogged with creosote and leaves will choke the flue. Your fireplace or stove starts acting like it’s never drawn air in its life, and the cure is often as simple as a new cap that can actually breathe.
Replacement Cost & What’s Included
A Gelco cap installation in Chester typically runs $225 to $385 installed, and the spread comes down to three things: the flue size, whether you have one flue or multiple, and how high and steep the roof is. A standard single-flue stainless Gelco on a one-story rancher off Harrowgate Road lands at the lower end. A multi-flue cap on a two-story colonial near Chester Village Green with a 10/12 pitch pushes toward the top and sometimes a touch beyond.
Every quote includes the cap, the mounting hardware, the labor to secure it to the flue tile properly, and a look at the crown while we’re up there. If the crown is cracked, we’ll tell you, show you photos, and quote a repair separately so you know exactly what you’re paying for. And like every job we do in Chester, the work backs up to our 90-Day Done Right Promise. If it’s not right, one call brings Wendell and his crew back at no charge.
DIY or Call Us?
Here’s the honest split. If you can safely get onto your roof and you’re comfortable up there, you can measure your flue tile and swap a cap yourself in about an hour with basic tools. That’s not a secret. What we’d caution you on is the ladder work and the roof pitch. A lot of Chester rooflines, especially the older two-stories near the village, are steeper than they look from the ground. The trip down is always faster than the trip up.
The part where DIY usually goes wrong on a Gelco cap is the anchoring. If the base isn’t square and snug on the flue tile, a good gust will take it to the neighbor’s azaleas. We see it every spring. If you’d rather not spend a weekend afternoon wondering if your ladder is rated for your own weight, call Wendell’s crew at (804) 392-9342. We’ll bring the right cap, the right ladder, and the experience to not have to make the trip twice.
FAQs
A stainless Gelco cap in Chester typically lasts 12 to 18 years depending on how much weather it faces and how often the chimney itself is maintained. Galvanized models run shorter, often 8 to 12 years, because the salt and humidity here in the Richmond area eat through the coating faster than drier climates would. If yours made it past 15, it did its job. Call (804) 392-9342 if you’re not sure whether yours has life left.
Sometimes yes, but not often. A torn screen mesh can be patched if the base and lid are still solid, which buys you a year or two. A rusted-out lid or a corroded base flange is a replacement job, because patching metal that’s already failing is just paying twice. We’ll tell you straight-up which one you’ve got. If it doesn’t need doing, I’ll tell you that too.
A standard single-flue Gelco cap swap takes about an hour from ladder up to ladder down, maybe an hour and a half if the old cap is seized and a multi-flue takes a little longer. Most folks in Chester schedule it around a chimney sweep and we knock both out in a single visit.
We stock common Gelco sizes on the truck and can order custom sizes if your flue is unusual. We also carry parts and caps from DuraFlex and HeatShield for other setups, so you’re not tied to one brand if your chimney needs something specific. Call ahead and we’ll confirm we have your size before we even schedule.
