Interior vs Exterior-Only Window Cleaning: What's Right for Your South Bay Home?
The most common question I get on the phone: 'Do I really need the inside cleaned too?' The honest answer is: not always. Here's how to decide for your South Bay home.
The quick answer
Most South Bay homeowners are best served by alternating: full interior + exterior in the spring, exterior-only in late summer near the coast, and interior refresh before the holidays. That mix keeps glass looking new and cuts total spend by roughly 25% versus doing full-service every visit.
When exterior-only wins
- Salt-spray refresh for coastal homes in Hermosa Beach or Manhattan Beach — interior is usually still clean from spring.
- Quarterly refresh for homes near sprinklers or pools.
- Pre-listing quick refresh for realtor photos.
- Post-Santa Ana wind cleanup.
When full-service wins
- Once a year in spring — always worth it.
- Before hosting a wedding, holiday, or open house.
- After remodeling or painting when interior glass is dusty.
- For homes with heavy interior condensation or pet-nose smudges on lower panes.

Frequently asked questions
Is exterior-only cheaper than half the full price?
Yes — roughly one-third off full service, because exterior takes more time than interior on most homes.
Do you still brush the screens on exterior-only jobs?
Yes. Every visit includes screen brush + rinse and exterior track wipe.
