Gelco Chimney Cap Installation Nationwide

Every visit starts with

Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

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 Installation: The Puyallup Owner’s Guide

Gelco chimney cap installation in Puyallup typically runs $340-$620 installed, depending on flue size and whether the crown needs repair before the cap can seat properly. We stock Gelco multi-flue and single-flue caps in common sizes for Puyallup’s prevalent 8×12 and 13×13 clay flue tiles, and most replacements are completed in under two hours with a written price agreed before we start. Most owners discover their cap has failed after finding rust stains on the chimney breast, water in the firebox, or - during a routine sweep - a cap that’s partially detached and clattering in a south wind off the Sound.

Which Gelco Models This Applies To

Gelco caps fall into three main series, and getting the right match matters because the mounting hardware differs. The Ultra series uses a band-clamp system around the flue tile itself; the Single-Flue line relies on leg brackets that tension against the flue walls; and the Outside Mount series secures to the chimney crown with masonry screws and a bead of sealant. We see the Ultra and Single-Flue most often in Puyallup’s 1970s-1990s rambler stock, where the flue tile extends a few inches above the crown.

To identify yours, look for the stamped Gelco label on the underside of the lid - usually visible from the roof edge with a flashlight - or measure your flue tile’s outside dimensions: width, depth, and the exposed height above the crown. The Single-Flue 8×13 and 13×13 are the two sizes we carry on the truck for Puyallup because they cover roughly 70 percent of what we encounter from South Hill to North Puyallup. Aftermarket equivalents from Olympia Chimney and Famco fit the same dimensions and meet the same 24-gauge galvanized or 0.024-inch aluminum specs, though Gelco’s stainless lid with the rolled edge tends to outlast them in our wet winters. Level Two Chimney Puyallup is an independent service provider, not affiliated with Gelco.

Signs Your Gelco Chimney Cap Installation Is Failing

Signs Your Gelco Chimney Cap Installation Is Failing
  • Rust streaks down the chimney face. Gelco’s galvanized steel body holds up well, but the spot-welded corners and the mesh screen’s attachment points are where moisture collects first. Once rust appears, the metal is thinning and the cap will leak within a season or two.
  • Water in the firebox or damp odor after rain. This usually means the lid has warped or the mesh has pulled away from the frame, creating a gap. In Puyallup, wind-driven rain from the southwest exploits even a half-inch opening.
  • Mesh screen detached or sagging. The screen keeps embers and animals out; when it separates, squirrels and roof rats can enter. We find this most often on caps installed 12-15 years ago, when the spot welds finally fatigue.
  • Cap tilted or loose after wind. The leg brackets on Single-Flue models can slip if the flue tile has spalled or if the original installer didn’t set the tension screws properly. A tilted cap channels water inward instead of shedding it.
  • No cap visible at all. It happens - high wind or a glancing blow from a branch can send a corroded cap off the roof entirely. The flue is now open to everything the Pacific Northwest throws at it.

Replacement Cost & What’s Included

Here’s what Gelco chimney cap installation costs in Puyallup, with the full scope spelled out upfront:

Service Price Range
Gelco-compatible single-flue cap, standard size, installed $340-$460
Gelco-compatible multi-flue cap or oversized single-flue $480-$620
Crown wash or minor crown repair (required for proper seating) $180-$340 additional
Flue tile repair or replacement if spalled Quoted after camera inspection

The range depends on three things: cap size and material grade, whether the existing crown is sound enough to seal against, and whether we need to fabricate a custom adapter for an odd flue dimension. Every quote is written before work starts - Haven Standard Clause 1 - and includes the cap, stainless fasteners, high-temp sealant, and a photo record of the finished installation. The 365-Day Done Right Promise covers labor and workmanship; manufacturer’s defect coverage runs through the part itself.

An owner can safely check whether the cap is present, whether it’s sitting level, and whether the mesh is intact - all from the ground with binoculars or from the roof if you’re already comfortable up there. What you cannot safely assess is whether the flue tile beneath the cap has spalled or cracked, which is common in Puyallup’s freeze-thaw cycles and determines whether the new cap will seal at all.

Installing a chimney cap requires working at roofline height, often on a wet or mossy surface, with power tools near the edge. The cap itself is not dangerous to handle, but a fall is. More importantly, a cap installed on a damaged crown or flue tile will leak silently for years, rotting the framing you cannot see. Camera goes in first. Price gets written down second.
