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.
Olympia Chimney Chimney Cap & Crown in Haverhill: What to Know First
Olympia Chimney cap and crown work in Haverhill typically runs $240-$680 for cap replacement and $750-$1,400 for a full crown rebuild, with most jobs completed in a single visit. We’re an independent Olympia Chimney service provider, not a factory rep, which means we’ll tell you straight whether that cracked crown needs immediate attention or can wait another season. If you own a home along the Merrimack or up in Bradford with an Olympia flue system, this page covers the failure patterns we see most, what repair actually costs, and how we approach the job differently. Call (978) 724-7935 and you’ll get a live person and a straight answer.

How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney’s stainless caps with riveted seams loosen at the collar after 6-8 New England winters. Freeze-thaw cycles in Haverhill work those rivets back and forth until the cap listing or rattling in the wind becomes audible from inside the house. We replace the cap with a properly fitted model and re-torque the collar to spec, not just snug enough to look right from the ground.
- The Olympia cap screen on the outside-mount models clogs faster than most. The mesh is tighter than what you find on gel-coated aftermarket caps, which is fine until third-season creosote glaze and leaf debris from Haverhill’s oaks plug it solid. A plugged screen turns a working chimney into a weak draft and a smoky living room. We clean the screen and, if the deterioration has started, swap in a replacement with a screen gauge that still passes Olympia’s airflow spec.
- Crown mortar on Olympia’s clay flue terminations spalls where the flue tile pokes through. This is the weak point we see most often on older Haverhill colonials near Bradford. The crown was poured tight to the tile, so when the tile expands and contracts with heat, the crown cracks at the joint. Water follows the crack, then freeze-thaw widens it. We rebuild the crown with a proper expansion gap or coat it with a flexible sealant depending on condition.
- Cast crowns on Olympia’s pre-fab chase tops hold water in the drip edge channel. The channel is shallow compared to aftermarket chase covers, and after a decade of Haverhill rain and snow it rusts through at the low points. Homeowners tell us they notice a rust drip line down the siding first. We fabricate a replacement chase top with a deeper drip edge and proper pitch so water actually leaves the top instead of pooling.
- Olympia’s multi-flue caps use a center support bar that corrodes at the welds before the cap body gives out. On a two-flue Haverhill chimney, one good windstorm can snap that bar and send the cap half-hanging over the flue. We’ve pulled more than a few of those down before they became a rooftop hazard. Replacement is a quality aftermarket multi-flue cap with heavier support framing, or OEM if the homeowner prefers, and we’ll show you the difference in cost and material thickness before you decide.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
Call and talk to a person. You reach a live voice, day or night. We ask what you’re seeing from the ground, when you first noticed it, and whether the chimney’s been serviced recently. Then we book a window that works.
- 2
Wendell or one of his crew shows up on time, in uniform. We bring the ladder, the camera, and the parts we think we’ll need based on your description, plus room for the unexpected.
- 3
We get eyes on the actual problem. Up on the roof or through the flue with a camera, we document everything. You see the photos before you spend a dollar.
- 4
We lay out your options in plain English. OEM Olympia replacement, quality aftermarket, or a repair that buys you a few more years. Warranty implications of each, the honest expected lifespan, and the price before a single tool comes off the truck.
- 5
We do the work clean. Drop cloths inside, magnetic broom around the hearth, roof left the way we found it. The cap or crown goes on, gets sealed or torqued properly, and gets checked for draft and clearance.
- 6
You get the 90-Day Done Right Promise in writing. If it’s not right, one call brings us back. No charge, no argument.

Why Haverhill Homeowners Call Top Hat Chimney for Olympia Chimney Work
Wendell Pike started Top Hat Chimney in 1999, and he’s been on Haverhill rooftops long enough to know which Olympia caps fail at year six and which crowns hold up for twenty. He learned the trade hands-on through the construction technology program at Southwestern College before heading northeast, and he’s the one who answers the phone most days. If it doesn’t need doing, he’ll tell you that too. We’re owner-operated, licensed, and we put the 90-Day Done Right Promise on every job in writing. When an Olympia part is backordered or discontinued, we pull from our other trusted lines, DuraFlex, HeatShield, and Gelco, so you’re not stuck with a tarped chimney while a factory catches up. One call to (978) 724-7935 gets you a straight answer, a real arrival window, and a sweep who’ll run into you at the hardware store on Washington Street next Saturday.
FAQs
Generally no for the cap itself, since Olympia Chimney’s warranty covers their manufactured components, not the entire system, but a mismatched or poorly installed cap can affect how the flue performs. We’ll show you the OEM and aftermarket options side by side, explain the material differences, and let you decide with the facts in front of you.
Most cap replacements and crown repairs are finished in one visit, usually the same week you call. Custom caps or full crown rebuilds take longer because of fabrication or cure time, and we’ll tell you the expected turnaround before you commit. Call (978) 724-7935 and we’ll get you a firm window.
If the cracking is surface-level and hasn’t let water through, a flexible crown coat often buys you five to eight more years for a fraction of the cost. If the crown is crumbling or separated from the flue tile, patching is wasted money. We’ll show you camera footage and give you the honest verdict either way.
You can knock off loose surface debris from the ground with some care, but the tight Olympia mesh holds creosote that needs a wire brush and a roof-safe position to remove properly. If it’s third-degree glaze, and we see plenty of it on Haverhill chimneys that burn softwood, that’s a job for a sweep with the right tools. Call us before you rent a ladder and find out the hard way.
No trip charge inside our own service county. Haverhill is home turf. The estimate is free, and you get the price before we start working.
