Approach 1: AvoidanceNo, this isn’t to suggest a pass from basic upkeep, but you can avoid a host of potential larger issues by incorporating a few basic elements into your log home’s design at the onset. Wrap-around porches and deep overhangs keep rain from coming in direct contact with your logs. For extra protection from moisture, keep exposed log ends properly sealed. (They’re one of the most vulnerable parts of the log, according to Jim McCain, founder of Weatherall Company, a stain and sealant manufacturer.) Include gutters and downspouts to channel precipitation away from your home.
If you live in snow country, build a foundation high enough so your first log course is at least 6 inches above your average accumulation.
Approach 2: DIYTo keep your log home healthy and happy, the most elementary thing you can do is also the easiest and least expensive — keep the exterior clean. “All you need is a garden hose, a sprayer and a bottle of gentle detergent, like Dawn dishwashing liquid or Simple Green,” says Tom Kuhns with Log Building Maintenance and Restoration in Milton, Pennsylvania. It only takes an hour or two, depending on the size of your home, but it’s time well spent. “Do this on an annual or semi-annual basis on a new log home, and you can prevent a lot of problems from happening, like layers of dirt from mowing the lawn or pollen buildup. This simple job extends the life of your finish and your logs,” Tom says.
According to Tom, if you don’t keep your logs clean, dirt particles will not only sit on the surface of them, but become embedded in the finish, especially in the summer when the log exterior gets warm. Left unchecked, the sun can essentially bake the debris into the stain or top coat. If this happens, a simple cleaning won’t remove it. Don’t panic, though. Jim suggests a light sanding with a palm sander may do the trick. However, if you do this, you will have to reapply a top coat to seal and protect the wood. Be sure you the logs are sand-dust free, clean and completely dry before you reseal.
Another thing you can tackle yourself on the cheap is mild mold/mildew removal. A periodic walk around the perimeter of your home will clue you in. Pay close attention to the logs closest to ground level and near the eaves/overhangs, especially on the north side of your home, which won’t get as much direct sun. Depending on the kind of mold it is, it can be almost black, white or bluish-green and can be patchy or textured. If you see it, deal with it immediately. You don’t want it to get underneath the stain/top coat.
