Composite Decks

Frequently Asked Questions


How do you clean composite decking?

With a mixture of either soft washing, pressure washing, or a bucket and a soft bristle brush. Each brand and model has different cleaning instructions, so we always check with the individual manufacturer and ALWAYS do a test spot first in an inconspicuous area.​

Can I Use Bleach on a Trex Deck?

Yes. However, the use of Sodium Hypochlorite may lighten the color of the deck. Always perform test spots before cleaning. Start with a light mixture and work up to only the strength required to clean.​

Is it safe to use high pressure on a composite decking?

Not Always. Each manufacturer has guidelines on the maximum pressure that their decking material should be cleaned with. Follow manufacturer’s guidelines to insure you are not going to cause damage​

Will pressure washing/soft washing void the warranty?

It absolutely can if the cleaning process is outside of their recommended guidelines. Any damage that occurs when outside of the company's guidelines can and will void their warranty.​
