Why Is My Chimney Pulling Away From My House?

You look up at the chimney and notice something that seems out of the ordinary. It appears that it is leaning or pulling away from the house. Well, if you have your own leaning tower on top of your Connecticut house, it’s a severe problem that needs immediate attention but is fixable.

Even if you don’t believe your chimney is in imminent danger of falling, you must contact a Certified Chimney Sweep® immediately. Strong winds, lightning, heavy rain, foundation settling, and other issues can cause bricks to loosen and fall off. This can further destabilize the chimney, partially or entirely collapse. Since masonry chimneys can weigh up to twelve tons, falling bricks from a collapse can cause severe injuries and property damage.

What Is Causing My Chimney to Pull Away?

Several problems can cause a leaning chimney:

Flashing Damage:

The flashing is sheet metal that seals the seam between the roof and chimney. When the flashing is compromised, moisture seeps through the tiny gaps, loosening the seal, and ultimately the stack begins to separate from the house.

Spalling Bricks:

When masonry damage is left unrepaired, the moisture-damaged bricks can crack, chip, and flake. This, along with mortar decay, leaves gaps in the joints, destabilizing the chimney and causing it to lean.

Inferior construction:

Another common cause of a leaning chimney is shoddy construction, usually by someone who needs to gain professional certification or experience with properly building a masonry chimney.

Foundation Settling:

Foundation settling is another reason your chimney may be pulling away from your house. Also, cracks in the foundation that allow rain or snow to leak inside can soften the soil, damaging the concrete chimney footing and causing it to lean.

Footing is Too Small:

If your chimney wasn’t constructed properly, then chances are that the footing is too small to support the weight of the structure. The slab below the chimney must extend at least six inches on all sides of the base. Otherwise, the moisture in the soil will cause the foundation to shift as the concrete expands and contracts.
