I was motivated by an astronomical bid from a local contractor and decided to invest $170 to determine if I could do it myself instead.
Power washer worked like a charm, removing grime and mildew in no time at all. Property is located in Blue Ridge section of North Carolina and winters can be harsh coupled with the fact I am surrounded by trees (keeps it cool but very little sun).
Now that I own the power washer, I intend to keep after the deck more diligently.
My question is- If I keep after the deck with the power washer regularly do I need to apply a wood preservative? The deck is 5 years old.
Would appreciate suggestions from those more knowledgeable. Thanks
