Clean Windows, Better Light, Enhanced Curb Appeal
Your windows are one of the first things people notice — and they’re also one of the most overlooked when it comes to regular maintenance. Our residential and commercial window cleaning in San Jose, CA is designed to restore the clarity and shine of your windows, no matter how big or small the job. Whether you’re in a high-rise apartment in Downtown San Jose or managing an office near Santana Row, we’ll make sure your windows reflect the pride you take in your property. We offer:
Streak-free interior and exterior glass cleaning | Screen removal, cleaning, and reinstalling | Hard water stain removal caused by irrigation systems or rain runoff | Track and frame detailing | Skylight and glass balcony panel cleaning
Solar Panel Cleaning That Keeps You Powered Up
With San Jose’s abundant sunshine, solar energy is a smart investment. But dirt, pollen, and bird droppings can seriously reduce efficiency if left unchecked. Our solar panel cleaning in San Jose, CA helps you maintain peak performance from your system year-round. We clean rooftop and ground-mounted panels using:
Purified, deionized water to avoid mineral spots | Soft, non-abrasive brushes to prevent scratching | Safe techniques that protect both your panels and your roof | We recommend solar panel cleaning 2–4 times annually, especially in tree-lined neighborhoods like Cambrian Park or Berryessa
Gutter Cleaning to Prevent Water Damage
Clogged gutters are more than an eyesore — they’re a serious threat to your home or building. Overflowing gutters can cause roof leaks, basement flooding, and foundation damage, especially during rainy winters or stormy weather. That’s why our professional gutter cleaning in San Jose, CA, is one of our most requested services. We recommend having your gutters cleaned at least twice a year in San Jose — especially before and after the rainy season, or if your property is surrounded by trees. Our rain gutter maintenance includes:
Complete removal of debris from gutters and downspouts | Water flushing to confirm proper flow | Visual inspections for signs of wear or sagging | Minor repairs such as clearing blockages and reattaching loose segments
Power Through Dirt and Grime with Pressure Washing
If your driveway is discolored, your patio is slippery, or your siding looks dull, it’s time to call in the professionals. Our pressure washing service in San Jose, CA delivers dramatic results across a wide range of outdoor surfaces. We use commercial-grade power washing equipment with adjustable settings to ensure every surface gets the treatment it needs without any damage. For tougher stains, we use biodegradable, plant-safe cleaning solutions. We safely clean:
Driveways and concrete walkways | Backyard patios and decks (wood, composite, stone) | Building exteriors and siding | Poolside areas and fences | Commercial building exteriors and signage
Specialty Services to Keep Every Corner Clean
In addition to our core services, Mt Diablo Window Cleaning also offers:
- High Dusting: Ideal for commercial interiors or homes with vaulted ceilings and tall architectural features — cleaning HVAC vents, fans, beams, and fixtures that are hard to reach.
- Birdproofing: Humane bird deterrent systems for rooftops and solar panels that prevent nesting, debris buildup, and long-term damage.
These services are especially valuable in commercial environments and larger residential estates where every detail counts.
