A rain cap installed without measuring the specific flue dimensions is a guess in Allentown. 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 Allentown, NJ. 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 Allentown. 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 Allentown, NJ. Brushers takes those two minutes in Allentown.

The primary function of a rain cap is keeping precipitation out of the open flue in Allentown, NJ. 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 Allentown. Consistent direct precipitation exposure accelerates liner deterioration and mortar joint erosion inside the flue faster than any other single factor in Allentown, NJ. A correctly installed rain cap eliminates direct precipitation entry into the flue entirely in Allentown.
A rain cap with mesh sides physically prevents wildlife from entering the flue in Allentown. 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 Allentown, NJ. A correctly installed cap with intact mesh sides makes wildlife entry impossible regardless of how persistent the animal is in Allentown. It is the only permanent prevention available. Everything else is temporary deterrence in Allentown, NJ.
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 Allentown, NJ. Embers that exit an uncapped flue can land on wood shingles, adjacent structures, or dry debris on the roof surface in Allentown. A cap with correctly specified mesh size contains sparks without restricting normal chimney airflow in Allentown, NJ.
Leaves, twigs, seed pods, and windblown debris accumulate in uncapped chimneys particularly during fall and in areas with significant tree canopy in Allentown. 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 Allentown, NJ. A rain cap with mesh sides prevents debris accumulation entirely in Allentown.
What an uncapped chimney looks like after five years in Allentown, NJ: 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 Allentown. Every one of those conditions is entirely preventable with a correctly installed rain cap in Allentown, NJ.

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 Allentown, NJ. 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 Allentown. 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 Allentown, NJ. An undersized cap provides the appearance of protection while allowing the specific things it was installed to prevent in Allentown.
A cap significantly larger than the flue it covers creates airflow turbulence at the flue exit that can impair draft performance in Allentown. 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 Allentown, NJ. 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 Allentown.
Brushers measures the specific flue dimensions before selecting any cap in Allentown. 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 Allentown, NJ. We do not estimate based on the chimney's external appearance or the homeowner's recollection of what size was there before in Allentown.
For a single-flue cap, correct sizing is based on the interior flue liner dimensions in Allentown. 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 Allentown, NJ. The mounting collar must engage the liner or chimney top surface correctly to create a weathertight connection in Allentown. 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 Allentown, NJ.
Single-flue rain caps cover a single flue opening and are the standard cap type for chimneys with one active flue in Allentown, NJ. Available in galvanized steel, stainless steel, and copper. Available in multiple designs from basic functional caps to decorative designs that complement the chimney's aesthetic in Allentown. Brushers sizes single-flue caps to the specific flue dimensions and confirms adequate overhang on all sides before installation in Allentown, NJ.
Multi-flue caps cover multiple flue openings with a single cap unit, appropriate for chimneys with two or more active or inactive flues on the same chimney structure in Allentown. A full-width multi-flue cap covers the entire chimney top with a single cover, providing comprehensive protection to all flues and the full chimney top surface simultaneously in Allentown, NJ. Brushers sizes and installs multi-flue caps across all chimney configurations in Allentown.
Full-width chimney caps, also called chase covers, cover the entire chimney top from edge to edge rather than just the flue openings in Allentown, NJ. Particularly appropriate for prefabricated chimney systems where the chimney top is a flat or sloped chase top requiring complete protection in Allentown. 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 Allentown, NJ.
Wind-deflecting caps convert horizontal wind pressure into upward draft rather than allowing it to push down into the flue in Allentown. The appropriate cap selection for chimneys experiencing wind-induced downdraft that a standard cap does not adequately address in Allentown, NJ.

This section matters if you are calling about a chimney leak and wondering if a rain cap is the complete solution in Allentown.
