Window Cleaning
Crystal-clear inside and out with pure, de-ionized water — no soap film, no streaks, no spots.
Locally owned. Brother run.
Streak-free windows.
Cleaner solar.
Raw pressure-washing power.
We're L&G Brothers — two local high schoolers bringing pro-level window cleaning, solar panel cleaning, and pressure washing to homes across the San Gabriel Valley.
What we do
Three services, one standard: leave every surface spotless.
Solar Panel Cleaning
Dust and dirt block sunlight. We restore your panels so your system runs at full strength.
Pressure Washing
Driveways, walkways, patios, and walls — we blast away years of grime, mold, and stains.
Why clean your panels?
Dirty panels waste the power you paid for.
Dust, pollen, and bird droppings block sunlight from reaching your solar cells. Clean panels catch more sun, which means your system produces more power and works more efficiently — saving you money every month.
- More sunlight captured, more power produced
- Better efficiency from the system you already own
- Gentle pure-water cleaning that protects your panels
Our method: pure water tech
We don't just spray and squeegee. We bring professional pure-water equipment to every job.
01
De-ionized water tank
Our tank strips out all the minerals and impurities from regular water, so nothing is left behind on your glass or panels.
02
Waterfed pole system
The pole feeds pure water straight to the brush — we clean up high from the safety of the ground, reaching windows ladders can't.
03
Zero chemicals, zero streaks
No soaps or detergents means no sticky residue to attract dirt again. Your glass stays clean, longer.

Questions we get asked
Straight answers about our services, pricing, and coverage area.
What areas do you serve?
L&G Brothers serves all of the San Gabriel Valley and parts of Los Angeles, including Pasadena, Arcadia, Monrovia, Glendora, West Covina, Alhambra, San Gabriel, Temple City, and nearby cities. If you don't see your city, call (626) 739-8249 and we'll let you know.
How much does window cleaning cost?
Every home is different, so we give free quotes over the phone or by text. Price depends on the number of windows, the height of the home, and whether you want inside and outside cleaned. Call or text (626) 739-8249 for a quote.
Does cleaning solar panels really save power?
Yes. Dust, pollen, and bird droppings block sunlight from reaching the solar cells, so a dirty array produces less electricity. Cleaning the panels lets them capture more sunlight, which makes the system you already own run more efficiently and produce more power.
What is a waterfed pole and de-ionized water?
A de-ionized water tank strips the minerals out of regular tap water, and a waterfed pole feeds that pure water straight to a brush on a long pole. Pure water dries without spots or streaks, and the pole lets us clean high windows safely from the ground with no soaps or chemicals.
What can you pressure wash?
Driveways, walkways, patios, pool decks, fences, and exterior walls. We remove built-up grime, mold, algae, and stains.
