Clear windows. Cleaner energy. Better curb appeal.
California Glass & Solar is the local solution Bay Area homeowners trust. Read on and you’ll learn which exterior services we offer, how we clean (purified water and soft brushes), sample pricing ranges, what customers actually say, and the easiest ways to request a free estimate.
We’re a woman‑owned, Campbell‑based team with 12+ years of Bay Area experience and custom, in‑house tools designed for local roofs and arrays. We recommend you ask to see current licensing and insurance documents before booking.
Why Bay Area homeowners choose California Glass & Solar
Local knowledge matters. We design brushes and workflow for the micro‑conditions you see across the Peninsula and into San Francisco—salt spray near the coast, pollen in spring, and dust after dry spells. That design focus reduces risk to delicate surfaces and gets better results than one‑size‑fits‑all equipment.
Being woman‑owned and neighborhood‑based gives the team two practical advantages: steady relationships with property owners and a willingness to adapt to the quirks of Bay Area homes. We bundle services so you don’t juggle vendors—one appointment, one safety plan, one invoice. That convenience protects asset value and simplifies maintenance ahead of resale.

What we clean — the services and the gains you can expect
Windows
What it fixes: streaks, hard‑water spots, coastal salt film, paint overspray and mineral deposits. Who benefits most: homeowners preparing to sell, people who work from home, and coastal properties. Recommended frequency: yearly or before a sale. Benefit: clearer views, more natural light, and improved curb appeal backed by a streak‑free approach.
Solar panel cleaning
What it fixes: dust, pollen, bird droppings and residue that reduce panel throughput. Who benefits most: arrays that sit flat or are exposed to traffic, trees, or wildfire smoke. Recommended frequency: annual, or more often in high‑soiling conditions. Benefit: clean panels reduce shading and surface loss so your array performs closer to its rated output. Learn more about our solar panel cleaning services for details on methods and scheduling.
Gutter cleaning
What it fixes: clogged channels, overflow, and debris that lead to water intrusion and roof damage. Who benefits most: properties with overhanging trees or heavy fall debris. Recommended frequency: twice yearly or after major storms. Benefit: reliable water diversion and fewer emergency repairs.
Soft washing and pressure washing
What it fixes: biological growth, grime, and surface stains. Use soft washing (low pressure and eco‑friendly agents) on siding, roofs, and stucco; reserve calibrated high pressure for concrete, driveways, and hard surfaces. Who benefits most: homes with mildew, algae, or oil stains. Benefit: surface renewal without surface damage.
Bird & pest deterrent and trash bin washing
What it fixes: nesting and droppings on arrays, and odors/hygiene issues from bins. Who benefits most: solar owners worried about bird soiling and property managers who need day‑to‑day sanitation. Recommended frequency: seasonal or as needed. Benefit: longer panel life, fewer shading events, and cleaner common areas.
Bundling window + gutter + solar cleaning in one visit saves time and often reduces cost—logistically it’s safer too, since the crew plans a single lift and a unified fall‑protection strategy.
How we clean: tools, methods, and safety practices
We rely on purified (deionized) water for solar and glass cleaning. Deionized water removes dissolved minerals so it dries without spots or residue. For panels and windows we use soft‑bristle brushes designed in‑house and water‑fed poles for reach; no abrasive pads and no harsh chemicals.
Soft washing uses low pressure plus eco‑friendly solutions for siding, roofs, and delicate trim. High‑pressure washing is reserved for concrete and masonry and is calibrated to avoid surface damage.
Our philosophy: no harsh chemicals, no walking on panels, and minimize runoff. Crews use roof‑safe techniques, fall protection, and vehicle signage. Ask to see proof of licensing and insurance when you book; we’re happy to provide documentation and explain our environmental safeguards for Bay Area runoff rules.
Micro FAQ — Will cleaning void my solar warranty? Generally no: non‑abrasive, professionally performed cleaning is industry standard and typically does not void warranties. Still, confirm with your installer and request a written note of methods before work begins.
Pricing, packages, and what shapes your quote
We price transparently: access, size and soil load drive cost. The examples below are orienting ranges, not guarantees; an on‑site estimate is the only way to get an exact, itemized price.
Typical sample ranges (examples only): solar panel cleaning $3–$10 per panel or $150–$350 for a 20–30 panel system; window cleaning $5–$15 per window or $100–$400 per home; gutter cleaning $100–$300 per residence. Please request a written minimum if you need one clarified for your job.
Price drivers include panel count, roof height and pitch, two‑story versus single‑story access, degree of soiling (bird droppings or paint overspray cost more to remove), ground‑level access versus lift rental, and whether multiple services are bundled.
Scenario guidance: a two‑story house with 24 panels and moderate dust commonly falls in the $250–$350 range; a three‑bedroom home with 20 windows plus gutters often lands in the $250–$500 neighborhood. Recurring plans or annual contracts typically lower the per‑visit price and help protect solar ROI over time. For context on regional pricing and cost drivers, see this guide to how much solar panel cleaning costs in San Francisco and this overview of solar maintenance costs.
Real results: reviews, before & after, and realistic expectations
Social proof matters. California Glass & Solar shows strong, recent customer sentiment—an aggregated five‑star average across 32 Google/Birdeye reviews reflecting professional, friendly, and thorough service. Reviews are easiest to find on Google and Birdeye.
“What a difference — my panels are producing noticeably more.” — customer
“Our windows and gutters were spotless; they even showed before/after photos.” — customer
Typical outcomes: cleanings commonly restore production by a noticeable margin in dusty or smoke‑affected conditions—gains often fall in the 10–30% range depending on the environment, panel tilt and time since last service. In areas that get regular rain, the incremental gains are smaller. The clearest way to judge impact is to compare your inverter or generation report before and after the clean.
When hiring, look for before/after photos, an itemized invoice, recent online reviews, and a willingness to show results during the visit. Reviews are easiest to find on Google and Birdeye; we post sample photos during every job to demonstrate the work.
