Crown sealing
A crown coating bridges small cracks to protect the most exposed part of the chimney.
A Abington chimney technician can apply a siloxane-based water repellent to chimney masonry, after cracks, joints and the crown are repaired. One call to (267) 715-3132 reaches a nearby chimney waterproofing pro.
A chimney standing above the roof takes rain from every direction, and its brick and mortar absorb much of it. Over time, the moisture feeds freeze-thaw damage, efflorescence, rusted dampers and deteriorated flue tiles. Waterproofing reduces how much water the masonry absorbs in the first place.
Choosing the right product is the whole job. Breathable repellents work below the surface: rain beads off, but vapor from inside can still escape. Paint, acrylic coatings and film-forming sealers do the opposite: they trap moisture inside the brick, and when it freezes, it blows the face off the brick.
Waterproofing does not fix damage, it protects repairs. If the crown is cracked or the joints are open, water will get in no matter how much repellent is applied. Once repairs have cured, the repellent is applied to clean, dry masonry.
If the problem goes deeper than it first looked, an Abington chimney sweep may also recommend chimney leak repair or chimney tuckpointing.

The masonry, crown and flashing are checked, since waterproofing does not replace repairs. Previous sealers or paint change the plan.
Every water entry point that repellent cannot handle is repaired. New mortar needs time to cure before treatment.
The brick is cleaned of dirt, efflorescence, moss and loose material. Clean masonry absorbs the repellent evenly.
The chimney needs to be dry so the product can soak in. Timing around the weather matters.
The repellent is sprayed or brushed on evenly, from the top of the chimney down. The crown typically gets a separate flexible crown sealer.
Once cured, water should bead on the brick instead of soaking in. A breathable repellent leaves no glossy coating on the brick.
A crown coating bridges small cracks to protect the most exposed part of the chimney.
Stains and deposits are removed for an even result.
The chimney masonry gets a penetrating water repellent to slow freeze-thaw damage.
The joint at the roof is inspected and sealed as part of a complete waterproofing job.
An open flue gets a screened cap which protects the damper and flue tiles.
Sealing a chimney goes beyond the brick: it covers the crown, flashing, cap and masonry. Each part gets a product made for it: crown coating for the crown, proper flashing and sealant at the roof, a cap for the flue and repellent for the brick. The common thread is that every product used on the masonry must let moisture escape.
For Abington homeowners, the biggest risk with chimney sealing is the wrong product. Paint and non-breathable sealers hold water inside the brick, and winter freezing then breaks the brick apart. If the chimney already has paint or a sealer, ask the chimney sweep how it affects the plan, since it may need to wear off or be removed first.
Chimneys in Abington see rain, snow and freeze-thaw cycles that test any masonry year after year. Homes in Abington and nearby towns like Roslyn, Willow Grove, Jenkintown and Glenside include many brick chimneys that have soaked up decades of rain, along with some that were painted or coated with the wrong sealer, and treating the chimney before winter gives it the best protection.

Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. Masonry takes the worst of it from the freeze and thaw cycle: rain and melting snow soak into the crown and joints, then freeze and push them apart, and each winter widens the cracks a little more. Wind driven rain from coastal storms finds any gap in flashing, too. Most homeowners in Abington, PA schedule a sweep in early fall, and a repair check after a hard winter.
Small chimney problems caught early usually stay small repairs.
