Pressure Washing Questions

Why do I have to clean and seal my deck?

The day you finish installing a deck or other structure is the day trouble can start. Morning dew, rainwater and melting ice or snow are quickly absorbed by unprotected wood, causing it to soften and swell. Direct exposure to the sun’s heat causes drying, which makes wood shrink. Continuous cycles of wet and dry, swelling and shrinking, cause wood to warp, split, crack and check – all of which lead to premature wood degradation and expensive repairs.

Unprotected wood is also subject to surface graying caused by constant exposure to the sun’s ultra-violet rays. Persistent moisture exposure creates ripe conditions for the growth of mildew, mold, algae and other fungal organisms that feed on wood, eventually spreading across and staining the surface. Termites and other wood boring insects also use wood for a food source, causing ultimate wood rot and decay.
