Deck Staining & Sealing

Wood decks are beautiful, but Wisconsin’s weather extremes can shorten their lifespan. Even pressure-treated wood needs protection from sun and moisture to prevent rot, fading, mold and mildew. Protect your investment with regular deck cleaning and staining. 

Deck Refinishing & Maintenance

  • Power washing to remove dirt, mold and mildew
  • Scraping and sanding to remove chipped paint and other loose material
  • Minor wood damage repairs
  • Deck staining with oil-based solid or semi-transparent deck stain
  • Deck painting with durable exterior-grade paint
  • Deck sealing with clear oil-based deck sealer
  • Deck maintenance for businesses, apartments and condo associations.
Schwaller's professional painters thoroughly prep the deck surfaces and use top-quality oil-based deck stain and sealer products for a protective finish that looks great. We cover your house siding and any concrete below the deck to protect it, and clean up spotlessly afterwards.

Frequently Asked Questions About Deck Staining

What are some signs that my deck needs to be resealed?

If your deck is peeling, faded, has a buildup of mold or mildew, or if water soaks into the deck boards without beading up, your deck needs to be cleaned and re-sealed. Sanding and re-staining may be needed before sealing depending on the condition of the wood once it's been cleaned.

How often should I stain my deck?

Oil-based solid color deck stain and semi-transparent deck stain typically need to be reapplied every 2-3 years, depending on what type of wood your deck is constructed with, the condition of the wood, and environmental factors such as sun and moisture exposure. Deck paint can last as long as 5-10 years.
