Should you worry about moss growth on your wood deck/railing systems? This is a fairly common occurrence in homes with older deck systems.
As it turns out, moss creates an environment conducive to elevated moisture conditions that could lead to deterioration over time. It may look pretty, but looks can be deceiving! Underneath moss growth that has been left alone for some time you just might find rotten wood…Yikes! Moss growth should be removed to safeguard against water intrusion/damage into the future, and to avoid bids to repair/replace your deck system.
The removal of organic growth from chimney systems is critical when it comes to preventing water damage and extending the serviceable life of chimney infrastructure. In the wet climate of the Pacific Northwest, this is especially pertinent.
During a recent inspection in Bellingham, I came across a chimney system with extensive organic growth. In this case, I recommended improving the system with a masonry sealant/water repellent, once organic growth had been removed. There are differing industry opinions about waterproofing masonry elements; some contractors argue that applying a sealant can make the issue worse and lead to masonry damage, others say that it’s absolutely necessary to prevent water damage. At a minimum, in my opinion, it’s imperative to keep moss growth maintained and prevent its growth on expensive masonry elements which can lead to costly repairs down the road.
