The main catalyst of moss and algae growth is the accumulation of leaves and debris on your deck, which will build up and retain moisture, especially after storms and inclement weather. This trapped moisture begins to spawn mold, mildew, moss, and algae – and the damper and darker the environment – for example, if your deck has natural shade or cover from trees – the more fertile the breeding ground.
If left untreated, your deck will not only look unsightly, it could pose a slipping hazard for your family and guests. Just as bad, that retained moisture will slowly begin to penetrate into the wood, causing cracks, splinters and ultimately, wood rot. And while less prone to wood rot, composite decking isn’t immune to the hazards of moss and algae; it can be as slippery and dangerous as a wood deck if moss and algae are left unchecked.
Don’t let debris build up on your deck in the first place. Keep it swept clean and make a point to regularly clear out any debris from cracks or gaps. Keep the surface as dry and openly exposed as possible to prevent moisture retention, bacterial growth and more.
At i5’s, we use the soft wash method to protect the integrity of the Vancouver decks we service. Rather than using a high-pressure or power wash, we gently remove the moss & algae and help bring your deck back to its former glory. Give us a call so we can discuss your needs.
