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 Installation: The Lawrence Owner’s Guide
A quality chimney cap installation on an Olympia Chimney system in Lawrence typically runs $275 to $520 installed, depending on the cap size, flue material, and whether the existing mounting hardware has corroded. We keep common Olympia Chimney-compatible caps stocked on the truck, and most installations are done in a single visit. What usually brings Lawrence homeowners to this page is simple: they spot rust flakes on the roof, hear a strange whistle when the wind picks up, or find sparrows making a mess inside the flue. The cap fails quietly for years before anyone climbs up to look, and by then, the damage has already started. If you’re reading this because your Olympia cap has finally given out, here’s what you need to know before you spend a dollar.
Which Olympia Chimney Models This Applies To
Olympia Chimney has manufactured caps and termination kits for a long time, and the part you need depends on the flue type and the year the system was installed. The most common Olympia caps we see on homes in Lawrence fall into three buckets: standard single-flue caps for masonry chimneys with round or square clay tile liners, multi-flue caps that span the entire top of a chase or wide chimney, and air-cooled termination caps for factory-built fireplaces where Olympia supplied the original venting components. The compatibility gotcha with Olympia is the liner measurement. The cap must sit over the flue tile itself, not the brick crown around it, and an eighth of an inch makes the difference between a snug fit and a cap that rattles like a loose tooth in every nor’easter. We’ve also seen plenty of Lawrence chimneys with rectangular flues that a round cap never should have been jammed onto. Older Olympia installations sometimes used proprietary locking tabs rather than simple tension screws, and if yours dates back fifteen years or more, we’ll confirm that before quoting. As for OEM versus aftermarket, the honest answer is this: for Olympia systems in good condition, a quality stainless aftermarket cap from a brand like Gelco or Famco often outperforms the original at a lower price. We stock both paths and will show you the difference in the metal before we ever pick up a drill.
Signs Your Olympia Chimney Chimney Cap Installation Is Failing
- Rust trails running down the chimney crown or brick faces. This means the cap body itself is rusting out, and on galvanized Olympia caps, that usually starts at the weld points where the hood attaches to the base. Once it begins, salt air from living near the South Shore accelerates it within two or three seasons.
- A new whistling or humming sound when the wind comes from the east. That’s air passing across bent or cracked hood slats, and it usually means the mounting hardware has loosened or the hood has warped out of shape. The previous cap might have been fine; the installation may have been the weak point all along.
- Sparrows, starlings, or wasps getting into the flue. A properly installed cap should have a mesh screen sized to keep birds out while still letting the flue breathe. In older Olympia caps, that screen can rot away while the hood itself still looks passable from the ground.
- Water staining on the ceiling near the chimney chase or fireplace. By the time moisture is visible indoors, the rain has been finding its way past a failed cap or a cracked crown for months. The cap is the first line of defense, but it’s rarely the only problem by then.
- Visible cracks or missing chunks in the cap when you look up from the yard. A hairline crack in the sheet metal spreads quickly with freeze-thaw cycles, and once a corner tears, that cap is not protecting anything anymore.
Replacement Cost & What’s Included
An honest price for Olympia Chimney-compatible chimney cap installation in Lawrence lands between $275 and $520 for most single-flue and standard chase caps, including the part and the labor. Larger custom multi-flue caps run higher because the metal work is bigger and the roof access gets more involved, but those are not common. What drives the range is straightforward: the cap size, whether we need scaffolding or a roof ladder setup, and whether the flue tile or crown needs minor prep work before the new cap goes on. On a standard installation, we secure the cap to the flue, re-tuck any loose mortar at the contact points if needed, and clear off whatever debris has collected on the crown. The camera doesn’t lie, so we photograph everything before and after. Every installation is covered by our 90-Day Done Right Promise: if the cap shifts, whistles, or leaks within three months, one call brings Wendell Pike and the crew back at no additional cost. We quote a flat price before the first tool comes off the truck, and the number you hear is the number on the invoice.

DIY or Call Us?
If you can safely view the cap from the ground or from a ladder you’re comfortable on, you can look for the obvious: heavy rust, missing mesh, or a hood that’s sitting crooked on the flue. That’s worth checking, and “if it’s clean, I’ll tell you it’s clean” applies to caps as much as it does to flues. What you should not do is take a ladder onto a Lawrence roof in January, drill into a masonry crown you can’t see the underside of, or guess at a flue measurement from the side of the house. A cap that doesn’t fit is worse than no cap at all because it gives you the illusion of protection while rain, birds, and sparks still find the gaps. We’re on roofs in Lawrence every week during heating season, and the older homes here have crowns that crumble under foot traffic if you don’t know where to step. If you’d rather not find that out the hard way, call (516) 604-2573 and we’ll take a look.
FAQs
A stainless steel cap on a Lawrence chimney with regular exposure to South Shore humidity and freeze-thaw cycles lasts roughly ten to fifteen years before the hardware or mesh begins to fail, while galvanized caps typically give you six to ten. The cap’s lifespan depends less on the brand name and more on the material grade, how well it was installed, and whether the chimney crown below it ever pools water. Call (516) 604-2573 and we’ll help you understand exactly what’s on your roof now.
If the failure is limited to torn mesh or a single loose mounting bracket on an otherwise sound cap body, we will often repair it right on the spot rather than sell you a new part you don’t need. When the hood is rusted through, warped, or cracked, a repair becomes a temporary patch that fails again next season. We’ll show you the difference with the camera footage and give you a plain-English verdict before any work is approved.

Most single-flue chimney cap installations we do in Lawrence take between forty-five minutes and an hour and a half, including setup, the install itself, and the before-and-after photos. If the crown needs a little tuck-pointing or the flue tile has a rough edge that needs smoothing, add on another half hour. The whole job is normally completed the same day we arrive.
We keep the most common Olympia Chimney-compatible cap sizes stocked on the truck so most installations happen in one visit. For unusual flue dimensions, custom multi-flue spans, or specific Olympia termination parts, we’ll order it and return once it’s in, usually within a few days. We also work regularly with parts from DuraFlex, HeatShield, Gelco, Famco, and Copperfield when an alternate brand is the better fit for your chimney. Top Hat Chimney is an independent local service provider and not affiliated with Olympia Chimney, which means we can match the part honestly rather than steer you toward whatever’s in stock in one particular catalog.
