Deck staining on Signal Mountain: shade, moss and mildew are the enemy

Why mountain decks go green

Under a full canopy, the boards stay damp for days after a rain. Leaves pile up in the gaps and hold water against the wood. That's where mildew, algae and moss get started, and why a Signal deck can look worse at three years than a sunny valley deck at five.

What we do differently up here

We spend more time on cleaning. We blow out the board gaps, use a mildew wash that's safe for the plants around the deck, and never blast soft wood with high pressure. We also steer most shady decks toward a stain made to resist mildew, and away from thick solid colors that trap moisture.

Log homes and cabins on the mountain

There are plenty of log and cedar-sided homes on Signal and Walden. We stain those too. They have their own needs, like checking for gaps in the chinking and dealing with old finish on the logs.

Best time to book in Signal Mountain

Same as the rest of the area: September and October are the sweet spot. The driest months here on average are October (3.59 in.) and August (3.67 in.)^NOAA. Fall dates fill first, so get your photos in early. Why fall works best.
