Olympia Chimney Chimney Cap Installation Nationwide

Olympia Chimney Chimney Cap Installation: The Northport Owner’s Guide

We stock and install Olympia Chimney-compatible chimney cap installation for Northport homeowners, with most jobs running between $380 and $720 installed depending on flue size and whether your crown needs repair at the same time. In most cases, we carry the right cap on the truck and can complete the work in a single visit. Northport’s salt-laden air off the harbor accelerates cap deterioration, so we see more calls than inland towns once the rust starts bleeding down the brick.

Most owners notice the problem after a storm, when water starts hitting the firebox floor, or when they spot rust streaks on the chimney breast during a routine walk around the property. Sometimes it’s a neighbor who points it out. Either way, a failed cap is an open invitation for water, animals, and debris to move straight down your flue.

Which Olympia Chimney Models This Applies To

Olympia Chimney caps are built to fit their own stainless steel and galvanized flue systems, and the critical detail is matching the cap to your flue diameter and whether you have a single or multi-flue setup. The most common Olympia Chimney caps we install in Northport are the 8-inch, 10-inch, and 13-by-13-inch models, though we’ve fitted custom-width caps for the oversized flues common in the 1920s colonials near Eatons Neck.

To identify your part, check the stamped label on the flue collar if the old cap is still in place, or measure the outside dimension of your flue tile or metal flue pipe. Olympia Chimney’s galvanized caps carry a 10-year warranty; their 304 stainless caps carry lifetime. We stock both, plus Gelco and Copperfield equivalents that meet the same specs when an exact Olympia Chimney replacement isn’t required. Hearthstone Chimney Co. is an independent service provider, not affiliated with Olympia Chimney. We’ll tell you straight whether the OEM part is worth the premium or if a quality equivalent saves you money without cutting corners.

Signs Your Olympia Chimney Chimney Cap Installation Is Failing

• Rust streaks running down the chimney face. Galvanized caps begin losing their zinc coating after 8 to 12 years in Northport’s coastal air. Once rust takes hold, the metal thins fast and the cap becomes a leak path instead of a shield.
• Water in the firebox or damp odors after rain. A cap with a cracked or missing lid, or a dislodged storm collar, lets water travel straight down the flue. In older Northport homes with unlined chimneys, that water soaks into the smoke chamber and breeds musty smells that linger for weeks.
• Mesh sides clogged or torn. The spark arrestor mesh on Olympia Chimney caps is 5/8-inch stainless weave. When it packs with creosote or gets torn by wind-driven debris, airflow suffers and ember protection disappears. We see this often after nor’easters blow through Northport Harbor.
• Cap sitting crooked or detached. The mounting brackets on galvanized caps corrode at the screw points first. A cap that shifts in the wind is one storm away from becoming a roof hazard or a complete loss.
• Bird or squirrel activity at the flue top. If animals are getting in, either the mesh has failed or the cap never had it to begin with. We’ve pulled nests from un-capped flues in Northport that blocked the chimney entirely and created a genuine fire risk.

Replacement Cost & What’s Included

What drives the range: flue height above the crown (taller requires ladder work or scaffolding access), whether the existing fasteners are seized and need drilling out, and whether the crown itself has cracks that should be addressed while we’re up there. Our estimate includes the cap, all fasteners and sealant, removal and disposal of the old unit, and a photo report of the finished work. Every installation carries our 90-Day Done Right Promise in writing. If the cap leaks or shifts, we come back. No paperwork, no arguing.

DIY or Call Us?

Here’s what you can safely check from the ground: confirm the cap is still present, note any visible tilt or rust, and listen for animal activity. Do not climb onto your roof to inspect it yourself. Northport’s older homes often have steep pitches and cedar shake roofs that are unforgiving. A chimney cap sits at the highest point, usually above a working flue that may be drafting hot gases. The installation requires proper ladder placement, fall protection, and the right fasteners for your flue type. Stripped screws or improper sealant lead to leaks that cost far more than the original install.

We carry Olympia Chimney caps and compatible equivalents on the truck, so most Northport jobs finish in one visit. Call (631) 528-2501 and we’ll give you a straight price before we book it.

FAQs

How long does an Olympia Chimney cap last in Northport?

Galvanized caps typically last 10 to 15 years near the harbor, where salt air is hardest on metal. The 304 stainless models often go 25 years or more. Call (631) 528-2501 for an exact quote on either option - estimates are free.

Can a damaged cap be repaired instead of replaced?

Minor mesh tears can sometimes be patched, but once the lid or base rusts through, replacement is the only sound fix. We’ve seen too many “repaired” caps leak again within a season. Call (631) 528-2501 and we’ll show you what we found on camera.

How long does the swap take?

Most single-flue replacements take 45 minutes to 90 minutes on site, including cleanup and photos. Multi-flue or crown-repair combinations may run two to three hours. Call (631) 528-2501 for an exact quote - estimates are free.

Do you stock Olympia Chimney caps?

We stock the most common Olympia Chimney sizes and equivalents from Gelco and Copperfield. For rare or discontinued sizes, we can typically source within 48 hours. Call (631) 528-2501 to confirm availability for your specific flue.

If the chimney’s doing its job, you won’t think about it. My goal is to keep it that way.
