  • To help bring out the true natural beauty of your deck, we first remove the dirt, mildew, old stains and sealers from the wood. We then apply a high-quality, penetrating oil sealer.

  • We begin the restoration process by applying an environmentally friendly cleaner to the entire deck. This loosens the dirt and mildew and also gets rid of the decaying wood fibers that give your deck that unsightly “gray” look.

  • The high quality cleaners and strippers we use allow us to clean away old sealers and stains at a very low pressure - which keeps your deck from being damaged.

  • The state-of-the-art equipment we use allows us to use varying amounts of pressure to clean any surface - no matter how tough or ingrained the dirt!

  • We then use a wood brightener, which brings the wood back to its natural color and neutralizes the cleaner and stripper. This step is very important to allow the sealer to work properly.

  • The deck is then allowed to dry thoroughly before sealing (we use an electronic moisture meter to ensure that the wood is ready).

  • Two coats of sealer are applied to the floor and the railing tops. One coat is allowed to soak in while the sealer is applied to the railings - then a second coat is applied to the floor (although not all sealers recommend two coats).

  • We use a brush or sprayer to apply the sealer to the railings, and a roller to apply the sealer to the floor. Rollers give a nice even coating, however a spray may be needed to get between the floor boards.

  • We follow the same process, and use the same products in the restoration of fences, cedar siding and cedar-shingled roofs, though the application methods may be different.


    Q. Does my deck really need to be sealed and preserved, even if it’s made of pressure-treated lumber that’s not supposed to rot?

    A. Any wood left exposed to the outdoor elements will cup, crack and warp if it is not protected from water penetration. Pressure-treated lumber is treated to prevent rot and decay but a quality wood preservative will prevent excessive water penetration and stop the changes in moisture content that
    can cause so much extra damage.

    Q. My deck has a gray color to it, can that be removed?

    A. It’s degraded wood fibers on the surface of the deck that cause that unsightly gray color. We use special cleaners to remove those fibers and also take away mildew and other dirt to really brighten up your deck and bring back its natural, new-looking color.

    Q. Can the old stain or sealer be removed from the deck?

    A. Old finishes will interfere with penetration so it is very important to remove any old sealer or stain before applying a new penetrating sealer.

    Q. Should I wait a year before sealing?

    A. A lot of homeowners are given bad advice to “wait a year for the wood to dry out” before sealing. But during that first year a lot of damage can occur, which is sometimes irreversible. Wood is often fully dried out within 6-8 weeks so we use an electronic moisture meter to ensure that the deck is ready to be sealed, and is therefore protected from the very start. That protection will help your deck last for many years to come.

    Q. Will the cleaning agents you use damage the grass or the bushes?

    A. No, the specially designed cleaners we use are safe on your shrubs and lawn.

    Q. How long does it usually take to clean a deck?

    A. Usually we will need one day for cleaning and one day for sealing - with enough time in between for proper drying.

    Q. Are you insured and licensed?

    A. Yes, we are fully insured and licensed.

    Q. Do you bring your own water?

    A. We are able to haul some water to the job site but some jobs require more water than we can haul. Please let us know in advance if water is a concern.
