Your home exterior’s siding will eventually collect grime and mildew. This can’t be easily removed with a rinse of a hose and a towel. It requires equipment that can apply just the right level of pressure to remove stubborn stains without causing damage. Here are the signs you need to pressure wash your house in Bothell.

Visible Dirt

Dirt gives the exterior a darkened and worn appearance. Dirt usually accumulates as a result of runoff from the roof. Water exits the downspout, hitting the floor and splattering dirt onto the walls. Pressure washing removes the grime that may have accumulated for months or even years.

Mold or Mildew

Due to the high humidity, mold and mildew can proliferate on the exterior walls or roof. If you spot blackish or greenish streaks, this is a sign of fungal growth. Mold is especially difficult to remove, and DIY remedies are often not recommended, and they’re often ineffective. It usually requires pressure washing from a professional.

Water Stains

Water stains are a byproduct of hard water from rain drying on the walls and leaving behind mineral deposits. This is another type of stain that is best treated with pressure washing. Water stains can be unsightly and make the exterior appear worn and aged.
