A rain cap installed without measuring the specific flue dimensions is a guess in Oronoco. A cap that is too small does not adequately overhang the flue opening and allows rain to enter at its edges in driven rain conditions in Oronoco, MN. A cap with mesh that is too fine restricts draft. A cap mounted without correct sealant at the cap-to-flue interface becomes a new water entry point rather than a water exclusion device in Oronoco. Rain cap installation done correctly takes about two minutes longer than rain cap installation done incorrectly, the time required to measure the specific flue before selecting the cap rather than grabbing the closest available size in Oronoco, MN. Brushers takes those two minutes in Oronoco.

The primary function of a rain cap is keeping precipitation out of the open flue in Oronoco, MN. Without a cap, rain falls directly into the open flue with every rain event, saturating the liner, accumulating on the smoke shelf, and in sufficient volume entering the firebox directly in Oronoco. Consistent direct precipitation exposure accelerates liner deterioration and mortar joint erosion inside the flue faster than any other single factor in Oronoco, MN. A correctly installed rain cap eliminates direct precipitation entry into the flue entirely in Oronoco.
A rain cap with mesh sides physically prevents wildlife from entering the flue in Oronoco. Birds, squirrels, raccoons, and bats can all enter an uncapped chimney flue. Each species brings complications including nesting material fire hazards, waste contamination, and in the case of chimney swifts, federal protected species protocols that prevent nest disturbance during nesting season in Oronoco, MN. A correctly installed cap with intact mesh sides makes wildlife entry impossible regardless of how persistent the animal is in Oronoco. It is the only permanent prevention available. Everything else is temporary deterrence in Oronoco, MN.
The mesh sides of a rain cap contain sparks and embers that might otherwise exit the flue and land on the roof or adjacent combustibles during wood-burning fireplace use in Oronoco, MN. Embers that exit an uncapped flue can land on wood shingles, adjacent structures, or dry debris on the roof surface in Oronoco. A cap with correctly specified mesh size contains sparks without restricting normal chimney airflow in Oronoco, MN.
Leaves, twigs, seed pods, and windblown debris accumulate in uncapped chimneys particularly during fall and in areas with significant tree canopy in Oronoco. Accumulated debris in the flue is both a draft obstruction and a fire hazard. Dry leaves and twigs in the flue path during fireplace use are combustible materials in direct contact with hot exhaust in Oronoco, MN. A rain cap with mesh sides prevents debris accumulation entirely in Oronoco.
What an uncapped chimney looks like after five years in Oronoco, MN: liner showing mortar joint erosion from consistent moisture cycling, smoke shelf with accumulated debris, possible animal nesting material from multiple seasons, efflorescence on upper masonry, and firebox moisture staining from water that entered in sufficient volume in Oronoco. Every one of those conditions is entirely preventable with a correctly installed rain cap in Oronoco, MN.

A cap whose cover area does not adequately overhang the flue opening allows rain to enter at the cap edges in driven rain conditions in Oronoco, MN. Wind-driven rain that hits the cap at an angle can be deflected under the cap edge and into the flue if the overhang is not sufficient to direct it away in Oronoco. A cap that is undersized in its mesh area allows animals to push under the cap edges because the cap is not large enough to create adequate contact with the liner or chimney top mounting surface in Oronoco, MN. An undersized cap provides the appearance of protection while allowing the specific things it was installed to prevent in Oronoco.
A cap significantly larger than the flue it covers creates airflow turbulence at the flue exit that can impair draft performance in Oronoco. It may also not mount securely to the liner or chimney top because the cap's mounting collar does not correctly engage the liner or chimney top surface in Oronoco, MN. A loose cap that is rattling in wind is a mounting failure that creates noise, accelerates cap wear, and eventually produces a cap that is not correctly positioned over the flue in Oronoco.
Brushers measures the specific flue dimensions before selecting any cap in Oronoco. The interior flue liner dimensions for single-flue caps. The full chimney top dimensions for multi-flue and full-width caps. The measurement takes two minutes and determines whether the cap being installed is the correct size for the specific flue in Oronoco, MN. We do not estimate based on the chimney's external appearance or the homeowner's recollection of what size was there before in Oronoco.
For a single-flue cap, correct sizing is based on the interior flue liner dimensions in Oronoco. The cap's cover must adequately overhang the liner by at least 2 inches on all sides to ensure rain driven from any direction is deflected away from the liner opening in Oronoco, MN. The mounting collar must engage the liner or chimney top surface correctly to create a weathertight connection in Oronoco. For multi-flue and full-width caps, correct sizing is based on the full chimney top dimensions including all flue openings and the surrounding masonry area in Oronoco, MN.
Single-flue rain caps cover a single flue opening and are the standard cap type for chimneys with one active flue in Oronoco, MN. Available in galvanized steel, stainless steel, and copper.

Brushers sizes and installs multi-flue caps across all chimney configurations in Oronoco.
Full-width chimney caps, also called chase covers, cover the entire chimney top from edge to edge rather than just the flue openings in Oronoco, MN.

Also appropriate for masonry chimneys where the crown is in poor condition and a full-width cap provides additional protection while crown repair is scheduled in Oronoco, MN.
