Vancouver's rain and humidity work on your deck year-round. These are real results from our deck and patio cleaning service across Greater Vancouver. Every job is photographed before we start and after we finish so you know exactly what you got.
Deck and patio work means chemicals and equipment on your property. Every WashTech job runs under full WorkSafeBC coverage. Your property is protected and so is our team.
If the result does not match what we quoted, we come back and fix it. You do not pay until the work meets your expectations. That is the standard on every job we do.
Leaves and debris from your deck end up in your gutters. Add a gutter clean to your visit and handle both in one appointment. Same crew, same day, no extra coordination needed.
WashTech carries $2 million in liability coverage on every job. If you need documentation for your strata council or property manager, we provide it on request.
Cedar splits, composite scratches and concrete etches if the wrong pressure is used. We assess your surface first, then choose the right pressure and solution for that specific material. Clean surface, no damage.

Once a year is the baseline for most properties across Greater Vancouver. Decks in shaded areas, under trees, or on the North Shore accumulate moss and algae faster because of higher moisture levels. If your surface feels slippery underfoot or you can see green growth starting, that is your signal to book a clean before the buildup does permanent damage to the wood or coating.
High pressure on the wrong surface will damage it. That is exactly why we assess your surface before we touch it. Cedar and older wood get soft washing at low pressure. Concrete patios can handle full pressure. We do not use one setting for everything and we will tell you upfront if your surface needs a specific approach.
Yes. Most jobs we complete cover both the deck and adjoining patio in a single visit. One quote, one crew, one day. If your gutters need attention at the same time we can add that to the visit as well.
