Pressure Washing & Exterior Cleaning FAQs
At Briand’s Exterior Washing, we believe informed customers make the best decisions. Here are answers to some of the most common questions we receive about pressure washing, soft washing, and exterior cleaning services throughout Barrington, Dover, Portsmouth, and the Seacoast NH area.
General Questions
Pressure washing uses high water pressure to clean durable surfaces like concrete and brick. Soft washing uses low pressure with specialized detergents to gently remove dirt, mold, and algae — ideal for siding, roofs, and decks.
Most homes in New Hampshire benefit from an annual cleaning. However, coastal or shaded properties may need washing twice a year due to humidity and algae buildup.
Yes! We only use eco-friendly, biodegradable detergents. Our soft washing process is safe for landscaping and outdoor areas.
Residential Services FAQs
We safely clean vinyl, wood, brick, concrete, stucco, and metal. From roofs and siding to decks and driveways, we use the correct technique for each material.
Absolutely. Those streaks are caused by bacteria called Gloeocapsa Magma. Our roof washing system removes it safely and restores your shingles’ appearance and efficiency.

Typically 12–18 months, depending on weather, shade, and pollen exposure. Soft washing kills organic growth at the root, so it lasts much longer than traditional power washing.
