Water in Your Chimney Means Mold


Why Do I Need To Worry About Mold?

Mold has its uses — there’s penicillin, which has proved to be a positive enough thing, then there’s letting you know where north is when you’re lost in the woods, or letting you know that its time (or, well, past time) to toss that leftover lasagna. We’re all pretty aware at this point, though, that mold in your walls, ceilings or chimney can cause some serious dangers to the people in your home — particularly folks who suffer from respiratory conditions. As mold spores spread through the air, inhaling them can cause allergic reactions, sinus problems, congestion and flu-like symptoms (headaches, coughs and throat irritation), even, in rare cases, more serious problems. And unless the mold problem is taken care of, those symptoms can continue. Toxic black mold, or Stachybotrys, is particularly worrisome, and commonly occurs when water gets into building materials.

Water in Your Chimney Means Mold - Baton Rouge LA - Basic ChimneyBasic Chimney techs will find any mold issues that might be hiding in your chimney masonry during your annual chimney inspection. But if mold starts to grow in between inspections, a few things will tip you to its presence.

Telltale Signs Of Mold

Foul odors

Mold has a musty, dusty smell that’s hard to miss. So if you’re noticing a foul odor coming from your fireplace, it’s worth giving Basic Chimney a call — your problem may not be mold, but chimney odors are a consistent indicator of some kind of problem in the system, and we can tell you what that is and recommend the best ways to solve that problem.

Leaks and stains

It’s usually easier to see mold in walls than on chimney masonry, but often enough, moisture issues that are significant enough to cause mold growth in your masonry will carry over to the surrounding drywall. If you notice the signs of a leak around your fireplace or chimney — particularly if you see dark stains — you may have a mold growth problem.

Preventing Mold Growth

The real key to preventing mold growth is the same key to taking good care of your chimney system overall: Do everything you can to keep water out. That means having your chimney inspected every year, to make sure leaks aren’t popping up in any common trouble areas (chimney crown cracks, flashing damage, degraded masonry); having a properly sized and correctly installed chimney cap protecting the flue; and keeping the chimney damper closed when the flue isn’t in use.

Waterproofing sealants can be a great preventative measure, too, helping the masonry itself stand up against rain and other kinds of precipitation.

If you think you might have a chimney mold problem, give Basic Chimney a call – our experienced technicians are here to help!
