An open flue is an open door — straight down into your home. Every Minnesota rain and snowstorm pours water into an uncapped chimney, and every spring, birds, squirrels and raccoons shop uncapped flues for nesting sites. A properly fitted chimney cap closes that door while leaving smoke a clear way out.
Eagle Chimney MN installs stainless steel chimney caps across the Twin Cities, sized and secured for your flue — single-flue, multi-flue and custom configurations.
What a Cap Protects Against
- Rain and snow entering the flue and soaking the liner and firebox
- Water damage to dampers, smoke shelves and interior masonry
- Birds, squirrels, raccoons and bats nesting in the chimney
- Leaves and debris building up into a blockage
- Downdrafts that push smoke and odor back into the room
- Sparks escaping onto the roof (the cap's mesh works as a spark arrestor)
Signs Your Cap Needs Attention
- No cap at all — the flue opening is bare
- A cap that's rusted, cracked, tilted or loose
- Rust stains streaking down the chimney below the top
- Scratching or chirping sounds from inside the flue
- Debris or nesting material visible in the firebox
- A cap that blew off in a storm and was never replaced
How We Install Caps
We start by measuring the flue and checking its condition — a cap fitted over a damaged flue top is a job half done, and we'll flag any crown or tile issues we find first. Then we fit a stainless steel cap matched to your flue's size and shape, secured so Minnesota wind can't worry it loose, with mesh sized to keep animals out while drafting freely. Before we leave, we confirm the fireplace draws properly with the cap in place.
