Most homes in San Diego County do well with a professional window cleaning twice a year. Homes close to the ocean usually need it more often, closer to every three months, because salt and marine layer film build up on glass faster than inland dust does. Whether you do it yourself in between comes down to three things: how high your windows are, how much buildup you are dealing with, and how much of the window you actually want cleaned.
Here is the longer version of each part of that answer.
How often windows need cleaning here
San Diego doesn't get enough rain to rinse glass for most of the year, so dirt builds up steadily instead of washing off. What builds up depends on where you live.
| Where the home is | What dirties the glass | A reasonable schedule |
|---|---|---|
| Within a mile or two of the coast | Salt spray, marine layer film, sand | About every three months |
| Coastal bluffs and oceanfront | Heavy salt exposure on large glass | About every three months |
| Inland North County | Dust, pollen, wind, irrigation overspray | About twice a year |
Homes in Oceanside, Solana Beach, Del Mar, La Jolla, San Clemente and Dana Point sit close enough to the water that salt is part of the schedule. Inland communities like San Elijo Hills, Del Sur and Rancho Santa Fe deal more with dust and wind, so the glass can usually go longer between visits.
A few signs your windows need cleaning sooner than the calendar says:
- A hazy film that looks worse in direct afternoon sun
- White spots where sprinklers or rain dried on the glass
- Gritty, dark tracks and sills when you slide a window open
- Screens that look gray from inside the house
What a DIY window clean usually misses
Cleaning your own windows is fine, and plenty of people keep up with the ground-floor glass between professional visits. It just tends to leave out the parts that take the longest.
- Screens. They hold dust that ends up right back on clean glass. Doing them properly means taking them out, washing them and letting them dry.
- Tracks and sills. Grit builds up where you can't see it until a window starts sticking.
- Second-story glass. Most people clean what they can reach and leave the rest.
- Hard water spots. Tap water carries dissolved minerals, so spraying windows with a hose and letting them dry often leaves spots behind. Our post on window cleaning near me covers why San Diego's water makes this worse.
- Salt film. On coastal homes, a quick spray and squeegee can smear salt residue around instead of lifting it.
None of that means a DIY clean is wasted. It means the glass you can easily reach is the easy part.
The height question
The most practical reason to hire someone is the windows you can't reach safely from the ground. Ladders are a real source of injuries: the U.S. Consumer Product Safety Commission estimated that about 227,000 injuries involving ladders and stools were treated in emergency departments in 2020.
A ladder leaned against a house can also bend gutters and scratch siding. RadPad cleans upper-story glass from the ground with extension-pole systems and purified water, so nothing gets propped against the building. If your home has second-story or awkwardly placed windows, that alone is usually reason enough to have them done professionally.
When doing it yourself makes sense
DIY is a reasonable choice when:
- Your home is single-story and every window is easy to reach
- You live inland, where buildup is mostly light dust
- You only want the outside glass touched up between professional visits
- You have the time to do screens and tracks, not just the panes
When hiring makes more sense
Hiring is usually worth it when:
- You have second-story, high or hard-to-reach windows
- You live near the coast and salt film keeps coming back
- Hard water spots are already on the glass
- You want the inside, outside, tracks, sills and screens all done in one visit
- You are getting the house ready to sell, or for guests or an event
What a professional visit includes
On a residential window cleaning visit, RadPad cleans interior and exterior glass with tracks, sills and screens included, not quoted as extras. The exterior pass uses purified water, so nothing is left on the glass to spot as it dries, and hard water and mineral spots are treated as part of the job.
For upper floors and large panes, high-rise window cleaning uses the same extension-pole approach. Storefronts and offices are covered by commercial window cleaning on a recurring schedule.
Booking it with the rest of the exterior
Windows don't need their own appointment. Plenty of homeowners book them on the same visit as gutter cleaning or solar panel cleaning, with one crew and one schedule. RadPad serves North County San Diego and south Orange County, including Oceanside, Carlsbad, San Elijo Hills, Encinitas, Solana Beach, Del Mar, Rancho Santa Fe, Del Sur, La Jolla, San Clemente and Dana Point.
If you're not sure whether your home is on a twice-a-year or a three-month schedule, send a few details and we will tell you what we'd recommend for your house.
