Not every damaged chimney cap needs replacing. A stainless cap that took a branch in a wind storm, a screen that a raccoon tore open, a hood that lifts and bangs because two legs worked loose: these are repairs, not replacements. Chimney cap repair means keeping the cap you have, fixing the part that failed, and fastening it so it stays put through the next storm. It costs less than a new cap and it is often a same-day visit.
This page is about repairing an existing, still-sound cap. If your cap has rusted through or is lying in the yard in pieces, you are on the wrong page; see chimney cap replacement. If the flue never had a cap at all, see chimney cap installation. The honest version of our job is telling you which of the three you need, and we do that during the free quote.
We repair caps across Seattle, Tacoma, Everett and the road-accessible Puget Sound, and we price match any written quote and take 10-25% off.
Symptoms
Signs you need chimney cap repair
- The cap hood is bent or dented on one side but the metal is not rusted
- Screen mesh is torn, pushed in, or missing a section
- The cap rattles, clanks or lifts at one edge in wind
- One or more legs or the band have pulled away from the flue tile
- Mesh is packed solid with creosote or fir needles and the fire smokes
- Sealant at the base has split and water is tracking under the cap
Common causes
- Wind storms and falling branches bending the hood or knocking the cap askew
- Raccoons or squirrels prying at the mesh to get into the flue
- Fasteners loosening over years of wind load and thermal cycling
- A cap that was slightly undersized and clamped to the tile on sealant rather than hardware
- Creosote or debris loading the mesh until it chokes the draft
- Crown cracking around the anchor bolts of a top-mount cap, so the anchors lose grip
How It Works
Our chimney cap repair process
We start by deciding whether the cap is worth repairing. Stainless and copper caps almost always are. Galvanized caps are a judgment call: if the hood is bent but the coating is intact, a repair makes sense; if rust has started at the bends or the welds, repairing it buys a year or two at most, and we say so. We also check why it failed, because a cap that loosened once will loosen again if the tile edge is crumbling or the crown is cracked under the anchors.
Assess repair vs replace
We look at material, rust, and what actually failed, then give you a straight answer: repair it, or put the money toward a replacement. Both options get a price if both make sense.
Straighten or rebuild the hood
Bent hoods and lids are reshaped and, where needed, re-riveted or re-welded. A lid that popped off its legs is reattached with new stainless hardware.
Replace the mesh
Torn or clogged screen is cut out and replaced with new stainless mesh sized for your fuel, so embers stay in and animals stay out without choking the draft.
Re-seat and fasten
The cap goes back on square and is clamped or bolted to the tile with stainless hardware. Top-mount caps get fresh anchors if the old holes have spalled.
Seal and test
Contact points are sealed, we confirm the cap does not move by hand, and we check the crown and flashing while we are up there.

Repair and service options
The repair we recommend depends on what broke and what the cap is made of.
- Re-fastening only: the cap is fine, it just came loose. New stainless bolts or a new clamp band, and it is done. The cheapest fix on this page.
- Mesh replacement: the hood is good but the screen is torn or plugged. New stainless mesh in the correct gauge. Often paired with a sweep if the old mesh was caked with creosote.
- Hood straightening or lid reattachment: storm damage to a stainless or copper cap. Reshaped, re-riveted and re-seated.
- Anchor repair for top-mount caps: when the crown has cracked around the bolts, we re-anchor into sound concrete or pair the job with crown repair.
- Replace instead: when the cap is galvanized and rusting, or the damage is more than the cap is worth. See cap replacement or upgrade to a stainless steel cap.
Our rule of thumb: if the repair costs more than about half of a new stainless cap, replacement is the better buy, and we will tell you that before you decide.
Pricing
What affects the price
- Which part failed: fasteners only, mesh, hood or anchors
- Cap material; stainless and copper are worth more repair effort than galvanized
- Single-flue versus multi-flue or top-mount cap
- Whether the mesh needs a creosote cleanout or a full sweep first
- Crown or tile damage that has to be fixed so the cap will hold
- Roof pitch and chimney height for access

Safety & Seattle Conditions
Safety considerations
A loose cap is tempting to fix yourself, and please do not. A cap that lifts in the wind can come off the tile the moment you touch it, and a wet Seattle roof is no place to be holding a sheet of metal. Call us; re-seating a cap is a quick job and same-day service is often available.
If the mesh is packed with creosote, the flue probably is too. Do not keep burning; a plugged screen pushes smoke into the room and the buildup behind it is a fire risk. We clean the mesh and the flue together.
Seattle & Puget Sound conditions
Most of the cap damage we repair comes from the wet season. About 73% of Seattle's 40.34-inch annual precipitation falls between October and March, which is also when wind storms knock branches onto roofs and push against any cap that is not fastened tight. A cap that survives summer loose will often be crooked or gone by December.
Moss plays a part too. Regional guidance notes Western Washington moss spreads fastest October through April on shaded, slow-drying surfaces, and moss growing at the base of a cap holds water against the fasteners and the tile edge. Part of a proper repair is clearing that contact area so the new hardware bites into clean, dry material.

Chimney Cap Repair FAQ
Is it worth repairing a chimney cap or should I just replace it?
Repair it if the cap is stainless or copper and the damage is mechanical: bent, loose, torn mesh. Replace it if it is galvanized and rusting, because rust does not stop and the repair will not hold. We check both and quote whichever makes sense, or both so you can compare. If the repair would cost more than about half of a new stainless cap, we recommend replacement.
My cap is rattling in the wind. Is that dangerous?
It means the cap is no longer gripping the flue and the next strong gust can take it off, leaving an open flue and a piece of sheet metal on your roof or in the yard. It is a quick re-fastening job when caught early. Call 206-453-2045 and we can often re-seat it the same day.
Can you replace just the screen on my chimney cap?
Yes. Torn or plugged mesh is the most common cap repair we do. We cut out the old screen and fit new stainless mesh in a gauge that suits your fuel; wood-burning flues need a coarser mesh than gas so creosote does not bridge it. If the old mesh was caked with creosote, expect us to recommend a sweep at the same time.
A raccoon tore my cap open. Will repairing it keep them out?
If we replace the mesh with heavy stainless screen and fasten the cap so it cannot be pried, yes. First we make sure nothing is living in the flue; see animal and nest removal. Capping an animal inside is worse than no cap. Once the flue is clear, the repaired cap closes the door.
The bolts on my top-mount cap pulled out of the crown. Can that be fixed?
Usually. If the concrete around the old holes has spalled, we drill new anchor points into sound crown and re-bolt the cap. If the crown is cracked across, the anchors will keep failing, and the right fix is crown repair or a rebuild with the cap reinstalled on the new surface.
How much does chimney cap repair cost in Seattle?
Less than a new cap in almost every case, and re-fastening a loose cap is one of the least expensive visits we make. The exact figure depends on what failed and what the cap is made of.
