How Freeze-Thaw Weather Damages Chimneys comes down to one process: water soaks into brick and mortar, freezes and expands by about nine percent, then thaws and leaves the masonry a little weaker than before. Over many winters, that repeated pressure cracks brick, crumbles mortar and opens the door to leaks. Your chimney sits higher and…
Why Chimney Bricks Start Cracking almost always comes down to moisture, heat or movement, and in Portland, moisture is the usual culprit. Rain soaks into porous brick and mortar. When a cold snap freezes that trapped water, it expands and can split the brick from the inside. A chimney fire or a shifting foundation can…
Brick chimney repair means fixing crumbling mortar, cracked or flaking bricks, a damaged crown, and leaking flashing before water spreads deeper into the masonry. Small localized jobs often cost a few hundred dollars, while full repointing commonly runs from $500 to $2,500 depending on scope and access. The earlier you act, the smaller the bill,…

No, you cannot use a damaged chimney safely, not even for one more cozy evening. A cracked flue liner, crumbling mortar, or a leaning stack can let heat, flames, and carbon monoxide escape into your walls and living space. If you notice damage, stop using your fireplace, wood stove, or any appliance vented into that…
Ignoring chimney damage allows small problems to grow into water leaks, crumbling masonry, fire hazards and carbon monoxide risks, and in severe cases the repair cost can come close to the cost of a rebuild. A hairline crack in the crown or a loose brick may look harmless from the driveway, but your chimney is…
Most chimney repairs take anywhere from a few hours to two weeks or longer, depending on the job. Minor repairs, such as replacing a chimney cap or sealing a cracked crown, are often finished in a single visit. Larger projects, such as flue liner installation, tuckpointing, or a partial or full chimney rebuild, fall into…
