Power washing your home or soft washing your roof/shingles removes them of air born contaminates that cause oxidization or mold contamination that decreases the value of your home. Pressure washing or soft washing can be done on almost any surface and is a great way to keep places like your driveway, house and deck looking clean and new.
Painting the interior or exterior of your home helps maintain or increases the value and also makes it more appealing to potential buyers as well as offering another layer of protection from harsh environmental elements.
Cleaning your gutters routinely every 6 months will prevent things like wood rot, water damage, and mildew growth. When gutters are properly cleaned and maintained they will keep water away from your home, preventing damage and erosion.
