Many homeowners try a myriad of techniques to get rid of the mold problems with decking. Yet the mold just keeps coming back! Is there a permanent solution?
In order to understand this mold problem, you need to realize that mold gets nutrients from cellulose-based materials and other organic substances. This includes wood. Most decking is made of wood, thus providing a food source for the fungi. Another point to realize is that mold and mildew are everywhere, you can never get rid of it all. But getting rid of what you can, keeps your home healthy and your deck looking pristine.
The key to solving the ‘mold on decking’ mystery, is to prevent the aggregation of mold spores in the first place. Once the mold takes hold and begins to proliferate, as you may already know, it’s a battle to remove it.
One solution to the problem is composite decking. This is a technology that is resistant to mildew, microbes such as mold, and other pests such as termites. You’ll also be doing your part in keeping the earth green, as the material is eco-friendly and is made from 50% recycled material such as plastic. It is not completely maintenance free, but rather, low maintenance.
Usually mold appears on decking solely because of high levels of moisture. It may be a good idea to gap the decking properly at a minimum of 1/8” so that trapped moisture can escape. Also make sure that gutters are not leaking or over flowing on the deck.
Another simple way to prevent mold from growing on your deck is to sweep it weekly especially in season such as spring and summer when pollen levels are high.
Water basting is a safe and effective way to get rid of mold on decking, as well as off the exterior walls of your home. It’s always safer to call in a professional, but it you choose to do the job yourself, please make sure you wear appropriate safety equipment such as goggles or safety glasses, gloves and dust mask. Don’t forget to protect any furniture and plants around the deck. Also, wear old clothes while doing the job, and make sure they are thoroughly washed soon after.
Tip: If possible, try spraying with hot water since most fungi cannot survive temperatures over 140 F. Again this is probably something that should be done by a professional, but should you choose to do it yourself, maybe you could make sure that young children are not home, and other people around the house know that you’re carrying out the procedure.
There are also affordable cleaning products available at basic chain stores. Some of these are extremely effective in loosening up the mold with no scrubbing at all. All you have to do is just water blast the residue away.
Getting rid of mold from your decking can be a frustrating and tedious job. The best solution is prevention. But once mold shows up again there are several techniques and cleaning agents that can help to keep your decking looking pristine.
