The Results
Wood, composite, and Trex decks cleaned and restored across North Idaho. The right pressure and method for each surface — protecting your investment while bringing back the look.
Too much pressure on composite or Trex decks raises the grain and creates permanent surface damage. Heritage calibrates pressure and technique to the specific deck material — wood, composite, or painted — based on an on-site assessment.
Heritage uses a professional wood brightener that neutralizes tannins and opens the grain so stain or sealer bonds properly. If you're planning to re-stain, Heritage's wash is the right prep — not a garden hose.
Heritage carries full general liability insurance. Idaho Contractor Registration #3481216. Before/after photos are standard on every job — useful documentation for homeowners, property managers, and anyone preparing a home for sale.
Heritage identifies the deck material, condition, and any areas of concern — raised grain, heavy mold, or sections that need special treatment. A written estimate is provided before any work begins.
We apply the appropriate solution and pressure for your deck type. Wood decks receive a wood-brightening wash that lifts oxidation and opens the grain. Composite decks are cleaned at low pressure with a targeted algae and mildew solution.
The deck is thoroughly rinsed. Before/after photos are taken. Heritage walks the completed surface with you and can advise on dry time before staining, if applicable.
Yes, but composite and Trex decks require low-pressure cleaning. High pressure on composite materials raises the surface grain and causes permanent damage that can void the manufacturer warranty. Heritage uses a low-pressure method with a professional solution specifically suited to composite materials. The result removes algae, mildew, and organic staining without any surface damage.
Yes — this is the most important prep step before any stain or sealer application. Stain applied over dirty, mildewed, or oxidized wood bonds poorly, fades faster, and won't provide the protection the product is rated for. Heritage's wood deck wash includes a brightening solution that neutralizes tannins and opens the grain so the stain can penetrate properly. Heritage recommends waiting 48–72 hours after washing before applying stain to allow the wood to fully dry.
Most North Idaho decks benefit from washing every 1–2 years depending on tree cover, sun exposure, and foot traffic. Decks under heavy pine or fir cover may need annual cleaning due to needle and sap accumulation. Heritage's annual residential program includes deck washing as part of a full exterior maintenance schedule.
In most cases, yes. Gray discoloration on wood decks is surface oxidation — UV exposure breaking down the top layer of wood fiber. A professional wood wash and brightener lifts the oxidation and returns the wood to a natural color. The extent of improvement depends on how long the wood has been weathering and whether there is any deeper damage. Heritage provides an honest assessment of expected results during the estimate.
Heritage comes to your property, walks the scope, and provides a written estimate. No obligation.
