Sunlight is free — lost watts aren’t. Dust, pollen, coastal salt and the occasional wildfire ash all sit on top of your panels and windows, silently costing you energy and curb appeal. Quick verdict: a Campbell-based, woman‑owned team with a 12+ year Bay Area track record uses purified/deionized water, soft brushes and custom tools to clean solar arrays, windows, gutters and more. If you want eco‑friendly, non‑abrasive maintenance from a local partner, this company is a good fit. Below: what they do, typical price ranges, how cleaning creates measurable value, and the exact next steps to get a free estimate.
At a glance — who they are and what sets them apart
Local profile: a woman‑owned exterior cleaning and property maintenance business based in Campbell serving San Jose and the greater Bay Area. Their strengths are practical: purified/deionized water systems that leave no mineral streaks, handcrafted in‑house brushes built to fit Bay Area roofs and solar arrays, and a full menu of services from streak‑free window work to bird deterrent and trash‑bin washing.
Why that matters: off‑the‑shelf brushes and high pressure can scratch glass and damage racking. Custom tools plus non‑abrasive methods minimize risk to panels, gutters and roofing while delivering longer‑lasting results. They also document jobs with before/after photos so you can see the difference.
Why professional panel and exterior care pays (energy, warranty, curb appeal)
Thin dust or a film of pollen can reduce peak output. Salt spray near the coast, bird droppings, or wildfire soot can cause larger, more immediate drops. Beyond lost watts, clogged gutters and dirty siding increase moisture risk and reduce property value—things a yearly check catches early.
Assume a household system that produces 6,000 kWh/year. Use a conservative production lift after a professional clean: 5–10%.
5% uplift = 300 kWh/year × $0.30/kWh = $90/year. 10% uplift = 600 kWh/year × $0.30 = $180/year.
If a professional full clean with inspection costs $300, payback is ~3.3 years at 5% uplift and ~1.7 years at 10% uplift. If your panels are heavily soiled (ash, salt, bird deposits), uplift can be higher and payback shorter.
Bottom line: cleaning pays fastest where soiling is frequent—near the coast, under trees, after wildfire smoke events, or on installations that rarely see rain. It also helps preserve warranties and reduces hotspot risk from uneven soiling.
Services explained — how they clean and what a typical job looks like
Solar panel cleaning
Start with a site inspection and photos. Technicians use soft, custom brushes and purified or deionized water to remove dust and deposits—no harsh chemicals or abrasive pads. Roof access protocols and fall protection are used where necessary; on‑roof work follows safety checks before any brush touches glass. After rinsing, the crew documents results with before/after images and a short report noting any issues (loose racking, debris buildup, bird nesting).
Window cleaning
Interior and exterior work employs streak‑free techniques and purified water for final rinses on exterior glass. Screens and frames are treated and, when requested, skylights and transoms receive the same careful attention. Multi‑story and storefront jobs use the appropriate access equipment and safety plans.
Gutters, pressure and soft washing
Gutter service includes full debris removal, downspout flushing and photo proof of clearance. Soft wash is the go‑to for roofs, painted siding and delicate materials—low pressure paired with eco‑friendly cleaning solutions. Pressure washing is reserved for hard surfaces like concrete and driveways where higher force is safe and effective.
Bird and pest deterrent, trash bin washing
Humane deterrents protect arrays from nesting and droppings without harming wildlife. Trash‑bin washing removes odors and bacteria—useful for property managers and homes alike.
Typical workflow
Crews arrive, run a safety briefing, inspect and photograph the site, perform the agreed cleaning with purified water and custom brushes, and finish with a walkaround and digital before/after photos. Every plan is tailored—no cookie‑cutter packages.
Pricing, packages and the real cost drivers
They do not publish fixed pricing online; the team offers free, site‑specific estimates. To set expectations, Bay Area market ranges are useful:
– Basic per‑panel quick clean: roughly $7.00–$10.00 per panel for light debris removal. Professional full clean with inspection: commonly $150–$500 depending on system size and access. Annual maintenance packages often run $450–$650 in Bay Area conditions.
What changes a quote: panel count and roof layout, roof pitch and story height, severity and type of soiling (salt, ash, pollen, bird droppings), need for lifts or special rigging, and whether services are bundled (solar + windows + gutters).
Illustrative sample quotes (ballpark)
Small home (12 panels, single story, easy access): $150–$250. Medium home (24 panels, two stories, moderate access): $300–$450. Large or complex systems: custom quote after inspection.
To decide whether to book, re‑run the quick math above with your actual annual kWh and a cleaned‑system uplift estimate. If cleaning plus inspection is a few hundred dollars and you expect multi‑year gains and warranty protection, it often makes sense to schedule a visit.
Reviews, credibility and what to check before you book
Local review signals show strong praise for promptness and quality on platforms aggregated to their profile (multiple 5‑star ratings). That said, presence on every review site is limited; Yelp and BBB entries are sparse. Positive testimonials repeatedly call out before/after photos and professional conduct.
Ask these questions during the estimate call:
- Can you provide proof of insurance and your contractor license number (if applicable)?
- Do you use purified/deionized water and soft brushes for solar panel cleaning?
- Will I receive before/after photos and a written report after the job?
- Do you offer a satisfaction guarantee or follow‑up policy for recurring customers?
Red flags: no insurance or unwillingness to show it, no written estimate, aggressive upselling, or inability to provide recent photo documentation or references.
How to book, prepare and what to expect on service day
Booking: call 1‑408‑661‑7747, use the online contact form on their website, or request a photo estimate. Their Campbell address (131B Lost Lake Ln, Campbell, CA 95008) anchors their Bay Area presence.
Homeowner prep—quick checklist:
- Clear driveway/parking for the crew and equipment.
- Secure pets and remove fragile items from work areas.
- Note gate codes or parking instructions for the crew.
- Photograph any pre‑existing roof or panel damage if you’re concerned.
Day‑of flow: arrival and safety briefing, site inspection and photos, cleaning using purified water and custom brushes, gutter clearing and final rinse where applicable, walkaround with the homeowner and delivery of before/after photos and recommendations. Most Bay Area homes benefit from one to two visits per year; schedule more often after smoke events or heavy pollen seasons. Recurring maintenance plans and referral incentives may be available—ask during the estimate.
Next step: call for a free, no‑pressure estimate and request a site‑specific quote plus proof of insurance. A short inspection is the only reliable way to turn general ranges into a precise price and care plan.
Deciding checklist: consider your local environment (coastal salt, trees, wildfire ash), how accessible your roof and array are, and whether you want documented, eco‑friendly service that protects energy production and curb appeal. If those matter, a local Campbell team that uses purified water, soft brushes and custom tools is worth a call.
