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 Wakefield: What to Know First
We provide independent Gelco chimney cap and crown service in Wakefield, with most jobs quoted in writing within 24 hours of your call and completed in a single visit once parts are on hand. A Gelco cap replacement typically runs $340-$620; crown repair or coating with Gelco-compatible materials ranges $480-$1,200 depending on access and flue count. Every quote includes a written scope, written warranty, and documented photo record before we start.
This page is for Wakefield homeowners who already have a Gelco cap or crown and need to know whether it can be repaired, what a quality replacement costs, and who can do the work without voiding whatever warranty remains. We are not affiliated with or authorized by Gelco. We are an independent service provider who sources Gelco parts through Haven’s buying network alongside DuraFlex, HeatShield, and other proven brands. If your cap is rattling in a nor’easter or your crown is shedding mortar into the flue, call (978) 861-1012. A live person answers, 24/7.
How Gelco Products Fail - and How We Fix Them
- Model A-1 and A-2 single-flue caps: The stainless mesh on these older Gelco units fatigues at the weld points after 8-12 years of Wakefield’s freeze-thaw cycling. The mesh separates from the frame and blows off in clusters, leaving the flue open to squirrels and water. We replace with a Gelco OEM A-series cap or a Haven-spec aftermarket equivalent with he-gauge mesh and a reinforced band weld, whichever gives you better coverage for the price.
- Multi-flue cap C-series (C-1 through C-3): The lid on these caps sits on a floating bracket system that corrodes where the galvanized bracket meets the stainless lid. In Wakefield, we see this accelerated on homes within a half-mile of Lake Quannapowitt where the humidity stays higher through shoulder season. The lid tilts, pools water, and dumps it between flues. We pull the bracket, assess the chase cover or crown beneath, and install a Gelco C-series replacement with 304 stainless brackets or upgrade to a unit with a one-piece molded lid if the chase geometry allows.
- Gelco crown wash products (CrownCoat and similar): These elastomeric coatings delaminate when applied over active spalling or freeze-saturated concrete. Homeowners sometimes get two seasons before the coating bubbles and peels. We do not coat over bad concrete. We grind back to sound substrate, patch with a compatible hydraulic cement, then apply the Gelco coating per spec with a wet-film gauge check. The repair lasts because the prep is honest.
- Chimney cap mounting on deteriorated flue tile: Gelco caps clamp or screw to the flue tile rim. When the tile is spalled or the mortar bed has washed out, the cap sits loose and shifts with thermal expansion. In Wakefield colonials built 1920-1950, we regularly find the top two feet of flue tile cracked from decades of this stress. We document the flue condition with the camera, rebuild the tile top with HeatShield-compatible refractory mix if the liner below is sound, then mount the Gelco cap to a surface that can hold it.
- Custom cap requests for non-standard flue profiles: Gelco’s standard line fits rectangular and round flues in common dimensions. Oval flues, offset twin flues, or exterior-mounted caps for historic Wakefield chimneys require measuring and often a custom fabricator. We take 12-point measurements, photograph the flue profile, and source through our Copperfield or Famco channels if Gelco does not stock the geometry. You get the same written price, same warranty, same Clause 4 photo record.
Our Gelco Chimney Cap & Crown Process

- 1
Call and schedule. A live person answers. We book a window, assign a named technician, and text you when they’re en route.
- 2
NFPA 211 Level 2 inspection with camera. We run the camera down the flue before touching the cap or crown. This finds the hidden damage that determines whether you’re looking at a cap job or a larger repair. Photos and footage are archived under Haven Standard Clause 4.
- 3
Written price, written scope, written warranty. Corrine Halstead’s standard: here’s what the camera found, here’s what it costs to fix it, everything else can wait. No verbal estimates. No “we’ll see when we get up there.”
- 4
Parts decision: Gelco OEM or quality aftermarket. We show you the exact Gelco model number or the aftermarket spec sheet. If your remaining warranty requires OEM, we source it. If not, we explain the trade-off in gauge, finish, and price.
- 5
Repair and test. Cap jobs get a pull-test on the mounting hardware. Crown jobs get a water mist test across the surface. We photograph the completed work from three angles.
- 6
Documentation and Done Right Promise. You receive the photo record, the written warranty, and our 365-Day Done Right Promise. If it’s not right, we make it right.

Why Wakefield Homeowners Call Level Two Chimney Wakefield for Gelco Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, every one with a written price before work started and a documented record when done. In Wakefield, that includes older colonials near Lake Quannapowitt where clay liner damage hides behind clean brick, and split-levels from the 1970s with original Gelco caps now past their service life.
Our technicians are background-checked, uniformed, and assigned by name. You get a text when they’re on the way. We source Gelco parts through Haven’s buying network, but we also carry DuraFlex and HeatShield materials when those are the better match for your repair. If another company has given you a written estimate, bring it. Our Free Second Opinion costs nothing and often clarifies whether the scope is right.
The 365-Day Done Right Promise applies to every Gelco job. Haven Standard Clause 1 requires the written price before work starts. Clause 4 requires the photo record. These are not marketing phrases. They are the conditions under which we operate.
FAQs
No, provided we use Gelco OEM parts where the original warranty terms require them. As an independent Gelco service provider, we are not bound to use only Gelco parts, but we will if your warranty status demands it. We check the manufacture date and series, then source accordingly. Call (978) 861-1012 and we’ll verify your coverage before quoting.
Most single-flue replacements take 90 minutes to two hours on site, including the camera inspection. Multi-flue caps or jobs requiring flue tile repair may run half a day. We quote the time estimate in writing with the price. Book your free estimate at (978) 861-1012.
Yes, in most cases. Gelco has phased out several A-series and early C-series lines. We cross-reference the dimensions against current Gelco stock and our aftermarket channels. If no exact match exists, we fabricate a custom cap to the same flue profile and mesh spec. The written quote shows both options.
Small cracks under 1/8 inch with no spalling or exposed aggregate can often be routed and coated with a Gelco-compatible elastomeric product. Wider cracks, spalling, or freeze-damaged concrete require rebuild. We do not guess from the ground. The camera and a physical probe determine the scope, and we show you the photos before quoting. Call (978) 861-1012 for an exact answer on your chimney.
NFPA 211 recommends annual inspection for all chimney systems. In Wakefield, we suggest a look at the cap and crown every fall before burning season, especially if your home sits near the lake where wind-driven rain and higher humidity accelerate corrosion. A Level Two inspection with camera finds crown damage that isn’t visible from the roofline. Schedule yours at (978) 861-1012.
Ready to know what your Gelco cap or crown actually needs? Call (978) 861-1012 any time. A live person answers, and we’ll have a written estimate to you within 24 hours.
