We will make your deck look as good as new!

Decks are beautiful additions to outdoor landscaping in Oregon & Washington homes. A wooden patio can be especially inviting for entertaining guests, hosting parties, barbecues, or simply sitting outside and enjoying a lovely evening.

Is algae taking over and causing it to be a hazardous slipping slide?

Your deck is actually not just dirty, it’s infected with microorganisms like bacteria, algae, mold, fungi and lichen. These microorganisms shorten the lifespan of your deck surfaces by decomposing the material itself. Sanitizing these surfaces can provide you a truly clean exterior.


Surfaces around the exterior of homes accumulate algae and mold growth over time, creating unsightly black and green streaks and stains. Rain and minerals can eat through the wood and cause your deck to deteriorate, so it’s important to keep it clean. However, the true danger lurks beneath the surface. Algae and mold feed off the wood and quickly deteriorate it if left untreated. As a result, you will be faced with a costly repair or replacement project if you don’t have the services of professional cleaners to handle deck washing for preventative maintenance.

Foot traffic, and our wet weather combine to create harmful and unsightly stains. Fortunately, there’s a way to curb this threat with the best deck cleaning in Vancouver!

Algae growth (green, brown, black) on a wood walking surface such as a stair, ramp, or deck may feel and look good harmless when it’s dry, but when there is even a modest level of dew, or water the surface can become more slippery than Teflon.

Moss and algae growth can be detrimental to the integrity of your deck if left untreated. It can also be slippery in damp conditions. And because moss and algae can spread and multiply very quickly, it’s vital to get rid of it at the first sign of growth.


Moss & Algae Growth

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.
