Chimney Cap Installation in Des Plaines: What You Need to Know
A chimney cap is a simple but critical investment for Des Plaines homeowners. Des Plaines has some of the oldest housing stock in the northwest suburbs, with many pre-1960 homes near the Des Plaines River. Age and persistent moisture from the river corridor create a high incidence of deteriorated mortar, spalling brick, and water-damaged flue liners. We see more chimney leak calls from Des Plaines than almost any other community we serve — the combination of old masonry and high moisture is relentless. Post-winter inspection every spring is especially important here. Without a properly fitted cap, rain, snow, and animals enter the flue freely — accelerating liner deterioration and creating blockages that can cause carbon monoxide to back-draft into the home.
Chimney Cap Installation — Our Work in Des Plaines
About Chimney Cap Installation
A chimney cap is a metal cover that fits over the top of the flue opening. It consists of a solid top that deflects rain and snow, mesh sides that allow combustion gases to escape while blocking animals and debris, and a mounting system that secures it to the flue or chimney crown. Chimney caps are available in galvanized steel, stainless steel, and copper, and in a range of styles to complement different chimney designs.
Without a chimney cap, your flue is an open invitation for rain, snow, birds, squirrels, and raccoons. Rain entering the flue accelerates liner deterioration and causes rust on metal components. Animals nesting in the flue create blockages that can cause carbon monoxide to back-draft into your home — and animal removal can be expensive and time-consuming. A chimney cap with a spark arrestor mesh also prevents burning embers from escaping the flue and landing on the roof or nearby combustibles.
Signs You Need It
- Your chimney doesn't have a cap (visible from the ground or confirmed by inspection)
- You've found evidence of animals in the fireplace or flue
- You notice water in the firebox after rain
- Your existing cap is rusted, damaged, or missing sections of mesh
- You've had a bird or animal nest removed from the flue
Our Process in Des Plaines
Flue measurement
We measure the flue opening precisely to ensure the cap fits correctly. An improperly sized cap can restrict draft or fail to seal the flue adequately.
Cap selection
We recommend the right cap material and style for your chimney — stainless steel for most applications, copper for premium installations, and multi-flue caps for chimneys with multiple openings.
Installation
We install the cap securely, ensuring it's properly anchored and that the mesh is intact and properly sized to allow draft while excluding animals and debris.
Crown and flue inspection
While on the roof, we inspect the surrounding crown and flue opening for any damage that should be addressed — and provide a written report of our findings.
