Frequently Asked Questions

  • What's the difference between pressure and soft washing?

    Pressure washing uses high-pressure water for hard surfaces like concrete and driveways. Soft washing uses low pressure with specialized solutions for delicate surfaces like roofs and siding.

  • How often should I have my house pressure washed?

    Most homes in New Hampshire benefit from annual pressure washing. Coastal properties near Portsmouth may need cleaning every 8-10 months due to salt air exposure.

  • Can soft washing damage my roof shingles?

    No, soft washing is specifically designed to be safe for asphalt shingles. The low-pressure technique with biodegradable solutions removes algae and moss without causing shingle damage or granule loss.

  • What causes those black streaks on my roof?

    Black streaks are caused by algae growth called Gloeocapsa Magma. This algae feeds on limestone in shingles and thrives in New Hampshire's humid climate, especially on north-facing roof sections.

  • How long does exterior house washing take?

    Most residential house washing takes 3-5 hours depending on home size and condition. This includes pre-treatment, washing, and final rinse for both siding and windows if included.

  • Will pressure washing remove oil stains from concrete?

    Yes, hot water pressure washing with appropriate degreasers effectively removes most oil stains from driveways and concrete surfaces. Older, set-in stains may require specialized treatment solutions.

  • When's the best time to schedule soft washing services?

    Late spring through early fall offers ideal conditions in New Hampshire. Avoid winter months when temperatures drop below freezing, as water can freeze on surfaces and equipment.

  • Do I need to remove outdoor furniture beforehand?

    Yes, please remove or cover outdoor furniture, decorations, and plants near cleaning areas. This protects your belongings and allows complete access to all surfaces requiring cleaning.

  • What affects the cost of pressure washing services?

    Cost depends on square footage, surface condition, accessibility, and service type. Multi-story homes, heavily stained surfaces, and additional services like window cleaning increase the overall investment.

  • How long do soft washing results last?

    Soft washing results typically last 4-6 times longer than pressure washing alone. Roof treatments can maintain clean appearance for 2-4 years, while house siding stays clean 12-18 months.
