Brick is porous — sealing it before freeze-thaw season is simple, practical insurance against spalling.
Brick is porous: it soaks up rain and snowmelt, and in Braintree’s climate the freeze-thaw cycle then expands that trapped water and cracks the brick from the inside out. Waterproofing with a breathable masonry sealer is preventative maintenance that dramatically slows this — and it costs a fraction of the repairs it prevents.
Not every chimney needs it on day one, and sealing a chimney that’s already crumbling does nothing. We’ll tell you honestly whether yours is a good candidate, and fix any open joints, cracks or crown issues first so the whole structure is protected as one system.
Waterproofing only works on sound masonry and only with a vapor-permeable (breathable) sealer that keeps liquid water out while letting the wall dry. Done right and at the right time, it’s one of the most practical ways to extend the life of a chimney.
