Composite Decks

Material dependent, we can seal composite decks such as Trex or other forms of synthetic wood to change colors or protect, seal, and revive aging materials.

Our Deck Staining & Sealing Prep Process

Prep is the MOST important part of an exterior painting project and the LONGEST part of the process. Our deck prep process ensures your paint has the most longevity possible. 

Power Washing

Before staining and sealing, we power wash the area to remove all dirt and grime ensuring we have a clean surface for a smooth application.

Masking & Protection

We cover all areas around the deck that should not be stained or sealed including landscaping, decorative areas, and your property.

Scraping and Sanding

We sand as-needed which smooths rough areas, removes old stain, and eliminates splinters.

Light Repair Work

We can do light repairs such as securing loose railings, nailing down steps, and replacing rotten wood (carpentry is an additional fee).
