To enjoy your deck or patio for many years, pay attention to maintenance in Pennsylvania. Decks need the most attention, unless made of vinyl. Every few years they need to be power washed and sealed to preserve the wood.

Deck sealers come in different shades to match the original color of the wood. Depending on the size of the deck and how elaborate the woodwork, it should take two or three days to wash and seal. Stains work best under certain weather conditions, so consult the weather forecast before you start the job.

Once poured, a concrete patio should be sealed for protection. If the patio is in a shady, damp area, it may need regular cleaning to limit moss or mold buildup.
