Deck Cleaning

Wood Treatment & Deck Cleaning

Keeping your deck clean is important. Not only does it keep your deck looking tidy, it also helps it last longer and reduces maintenance in the future. Slippery decks are a huge problem in Wellington over the winter months, but with a Chemwash clean, you can tread with confidence across your decks! We have over 25 years experience deck washing in Wellington, and can provide you with a free inspection & written quotation.

Deck Cleaning

Extend the life of your deck with a Chemwash deck clean. With our powerful, yet gentle deck cleaning detergent, we can restore even the greyest deck to near original colour. Traditional water blasting results in splintering, but our processes protect & restore the wood, reducing slip and ensuring your deck remains in the best condition possible. A clean could include deck floors, handrails, bench seats, trellis work, outdoor furniture & more. Just get in touch and we’ll see what we can do.

Pre-Paint or Stain Preparation

A Chemwash deck clean is also recommended for pre-paint or stain preparation. The perfect time to stain or paint your deck is right after a clean. Staining your deck will enhance the colour, protect the wood, and make it look great!
