FAQs
Is Water Coming from Chimney Dangerous?
According to the Chimney Safety Institute of America, a water-stained ceiling near your chimney is not necessarily dangerous. However, water seeping through the bricks and mortar of your chimney could be a sign of a bigger problem.
One common cause of water in your basement is condensation. If you have an unvented gas fireplace, humidifier, or clothes dryer, the warm air they produce can rise and meet cold surfaces in your attic or crawl space.
This produces moisture that can drip down onto ceilings and walls. Another potential source of condensation is leaky ductwork in your home’s heating and cooling system.
How Do I Stop Water from Seeping Into My Basement?
You can do a few things to keep water from seeping into your basement. One must ensure that your gutters and downspouts are clear of debris correctly to channel water away from your foundation.
Another is installing an interior drainage system to collect any water that leaks and direct it out of your basement. Finally, you can waterproof your basement walls with a special coating or sealant.
How Do I Find a Water Leak in My Chimney?
To find a water leak in your chimney, you’ll want to look for:
- Water stains on the ceiling or walls near the chimney
