What Our Clients Are Saying

Honest Clarity & Details

Common Questions, Straight Answers

  • Is your bird proofing humane and safe?

    Yes. We use non-lethal deterrents, including mesh, clips, and visual irritants—all safe for animals and pets.

  • Will solar cleaning damage my panels or void my warranty?

    Not at all. We use soft-bristle tools and DI water—exactly what solar manufacturers recommend for safe maintenance.

  • Do you use harsh chemicals in your washing services?

    No. We use biodegradable, eco-conscious detergents designed to protect your property and the East Bay ecosystem.

  • Are your technicians certified and insured?

    Yes. We maintain full Workers’ Comp and aerial certification to protect both your property and our crew.
