Yikes! What’s the weather like outside? Isn’t the relative humidity at 70%, 80%, even 90% on the East coast and in the south?

So opening a window and letting in humid air is going to do what? Right- it’s going to bring the humidity in. You’re going to cool that air in your basement or crawl space. So, if it’s 70% relative humidity and 85 degrees outside, and you bring that air into a 65 degree basement, what’s going to happen?

Well, the relative humidity is going to go up 2.2% for every degree that the air is cooled. So 85 to 65 degrees is 20 degrees – that’s a 44% relative humidity increase, for a total of 114% relative humidity. Can we have over 100% relative humidity?

No. So what happens next… the moisture in the air condensates out on cooler surfaces. That’s why cold water pipes, water tanks, soda cans, etc. get wet with condensation. They cool the air touching their surfaces and the moisture condensates out.

Uh-oh. Didn’t we just open the window and let that air in? What’s it doing? It’s supporting mold and mildew growth and compounding the musty smell that you opened the window to eliminate.

What’s the answer?

A dehumidifier. And one that can handle the size of your basement or home is important. If you can’t tell which way the air is moving through a dehumidifier, it can’t dry your space.

To protect the innocent, we’ve changed the names of the folks in our story:
Mr. and Mrs. Smith’s basement flooded once. They cleaned the gutters just like their cousin told them to. After all, he was a builder and he knew about these things. The couple didn’t see any more water in their basement for a good six months. They soon forgot about the incident and put all of their stuff back down in the basement on the floor. There were holiday decorations, tax records, a record album collection, personal effects – even Mrs. Smith’s preserved wedding dress – in a cardboard box like most of the other items. Beginning one otherwise peaceful evening, the sky opened up, as it does once every year or two, and two months worth of rain fell in two days. All of the Smith’s belongings were lost in the flood that resulted in the unprotected basement.

It doesn’t have to be a severe flood to experience the effects of water damage. Mold thrives on organic material so if you’ve got a high relative humidity or seepage, all of those personal items stored in boxes in the basement run the risk of being ruined. At the first sign of a problem it is important to begin the fixing process. Basement leaks do not get better, they worsen with time.

Fixing the gutters and downspouts is the first step, but not the permanent fix. For moisture, a quality dehumidifier will help alleviate mold and musty odors. SaniDry basement dehumidifier will do the trick, it’s like a dehumidifier on steroids! For foot and wall joint leaks or even floor seepage, a custom interior basement waterproofing system will solve the issue. WaterGuard, a patented system, is designed to accept wall, floor, and foot and wall joint leaks without getting clogged with dirt and debris. This is a much better solution than excavating the exterior and installing a new footing drain that will eventually clog up again. Paints or sealants are only a temporary solution and eventually the water will push through.

At the first sign of water in your basement, call a system design specialist so that you can avoid the mess the Smiths had to deal with.
