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.
Gelco Chimney Cap & Crown in Newark: What to Know First
Gelco chimney cap and crown work in Newark runs most homeowners between $185 and $640, depending on whether we’re repairing the existing crown, replacing a rusted cap, or fabricating a custom multi-flue setup. Most Gelco jobs are finished in a single visit, and we quote a flat price before any tool comes off the truck. As an independent Gelco service provider, we work on these products regularly, and we’ll tell you plainly if the repair can wait.
This page is for Newark homeowners who already have a Gelco cap or crown and want to know what’s actually wrong with it, what it costs to fix, and whether anyone in the city will give them a straight answer. Call (848) 331-2638 and you’ll get a live person, not a phone tree.
How Gelco Products Fail - and How We Fix Them
- Gelco LD Series caps with rusted screens. The LD Series was Gelco’s entry-level line for years, and we see a lot of them on Newark rowhouses in the Ironbound and Forest Hill. The expanded steel mesh screen corrodes first, usually right at the base where water sits. The cap itself is often fine. We replace the screen with heavier-gauge stainless mesh rather than swapping the whole unit, which saves a couple hundred dollars and keeps the original cap’s fit.
- Galvanized Gelco caps on wood-burning flues. Galvanized steel does not belong on a flue that vents a wood fire. The heat and acidic condensate eat through it in three to five winters. If you have a Gelco galvanized cap on a fireplace flue, we replace it with a stainless Gelco unit or a quality aftermarket equivalent and explain the difference in the report we hand you.
- Cracked crowns from unsupported cap legs. This is the big one. Gelco caps with leg mounts bolt directly to the crown, and if the crown was mixed too wet or poured thin, those legs create point-load cracking within two winters. Newark’s freeze-thaw cycle accelerates it, especially on the old masonry in the North Ward. By the time you notice a cap that wobbles, the crown underneath is already crumbling. We pull the cap, rebuild the crown with proper slope and a flexible bond break, then remount the cap with load-spreading hardware.
- Improperly sized replacement caps. We see homeowners buy a cap online with the right flue tile dimensions but the wrong base style. Gelco makes tops that fit inside the flue and tops that clamp outside it. Wrong fit means the cap whistles, tips, or lets wind-driven rain down the flue. We measure everything before ordering, and we’ll tell you if the cap you bought isn’t the right one for your tile.
- Crown wash that was never sealed. A bare mortar crown wicks water like a sponge, and many Newark homes got one in the 1980s that nobody ever treated. That same condition is the one we see on almost every house that calls about a Gelco cap that’s still intact but a chimney that leaks anyway. We seal the crown with a flexible coating rated for vertical masonry, not the old-school tar that failed in five years.
Our Gelco Chimney Cap & Crown Process
- 1
Call and talk to a real person. You reach Wendell or one of the crew. We ask basic questions about your setup, schedule a visit, and tell you if there’s a trip charge. Inside our service county, there isn’t one.
- 2
Get on the roof and look. We inspect the cap, the crown, the top three courses of brick, and the flue tile. We take photos and, if water inside the chimney is part of the story, we run a camera.
- 3
Get the plain-English verdict. You’ll see the camera footage and the photos. If the crown has small cracks but is still shedding water, we tell you it can wait. If the flue tile is spalling and the cap doesn’t matter yet, we tell you that instead.
- 4
Agree on parts and price. We use OEM Gelco where it makes sense, and quality aftermarket when it’s genuinely a better fit or faster availability. You approve a flat number before we touch anything.
- 5
Do the work. Cap and crown jobs usually run one visit, two to four hours. We protect the roof, keep the mess contained, and clean up like we were never there.
- 6
Walk the job with you. You see the finished work before we leave. Every job, including Gelco work, comes with our 90-Day Done Right Promise in writing. If it’s not right, one call brings us back at no charge.

Why Newark Homeowners Call Top Hat Chimney for Gelco Work
We’ve been on Newark rooftops since 1999, and we’ve learned the city’s flues one at a time. Wendell Pike still answers the phone half the time, and he’ll tell you if the job doesn’t need doing. Our crews are background-checked and arrive in uniform, with a real arrival window and a call if we’re running late.
Because we also work with DuraFlex and HeatShield products, we’re not stuck recommending one brand’s fix for every problem. If your Gelco cap is shot but your liner is sound, we say so. If the liner’s the real issue, the camera shows it. That’s the whole point: evidence first, recommendation second. Ask anyone on your street.
FAQs
A stainless Gelco cap installed on a properly built crown will last twelve to eighteen years in Newark; a galvanized cap on a wood-burning flue will last three to five. If you want to know which one you have without going up there, we can tell you during the visit, and we’ll show you the photos. Call (848) 331-2638 to book an inspection.
For caps, quality aftermarket stainless units are often as good or better than what’s on the truck from the factory, and they’re usually available faster. For multi-flue Gelco caps, Wrightworth and Olympia make solid equivalents that we install when the lead time on OEM is weeks. For anything warranty-related, we’ll always use OEM if that’s what’s required. We’ll give you the breakdown on cost and availability before we order anything.
We schedule Gelco cap and crown work inside one to two weeks in most cases. The busy season runs September through December, and fall fills early. If you’re seeing water or the cap has come loose, call (848) 331-2638 and we’ll tell you when Wendell or one of the crew can be there.
If the crown has hairline cracks but is still shedding water and structurally sound, yes, we seal it and charge for a repair, not a rebuild. If the crown has broken corners, exposed aggregate, or a gap at the flue tile, a repair won’t hold, and we’ll show you why before you spend anything. The camera footage and a plain-English verdict, every time, no exceptions.
Water gets into the masonry, freeze-thaw cycles do their work, and in Newark that means spalled brick, a cracked flue liner, or both. The cap and crown are the roof of your chimney. Once they go, everything under them goes faster. If it needs doing, we’ll do it. If it doesn’t, we’ll tell you that instead.
