Our Mission

At Dan Mount Cleaning Services, we help commercial and residential property owners in the San Francisco Bay Area maintain clean, inviting spaces with reliable window cleaning, power washing, exterior building washing, and more.

With 40 years of experience and a commitment to quality, we take pride in clear communication, flexible scheduling, and spotless results.

Why San Francisco Property Owners Call Us

San Francisco buildings take a beating. Salt air off the bay, fog that sits on glass for days, and the grime that builds up on older Victorian and Edwardian facades all mean that regular cleaning is not optional, it is maintenance. We understand how local conditions affect surfaces and we use the right approach for each one.

We use deionized water-fed pole systems for window work, which means no soap residue and no streaks, even on older single-pane glass common in the city. For exterior surfaces we match the cleaning method to the material, whether that is a painted building face, a brick stairwell, or a wooden deck.

We are fully insured and equipped for mid-rise work up to four stories, which covers the large share of San Francisco's residential and small commercial building stock.

How the Job Goes

You call or email, we talk through what you need, and we give you a written quote before any work starts. No surprises on the invoice.

When we arrive we do a quick walkthrough, confirm the scope, and get to work. We leave the property clean and do not leave a mess behind. If anything comes up during the job that was not visible at the quote stage, we tell you before we continue.

For recurring work, we schedule around you. For one-time jobs, we are straightforward about timing so you can plan around us.

Frequently Asked Questions

Do you clean windows on buildings taller than one story?

Yes. We are equipped for mid-rise work up to four stories. If you have a condo, apartment building, or small commercial property in San Francisco, call us and we will confirm we can reach what you need.

What is deionized water and why does it matter for window cleaning?

Deionized water has the minerals stripped out of it, so when it dries on glass it does not leave the white spots or streaks that tap water leaves behind. We use a water-fed pole system that delivers deionized water directly to the glass, which means cleaner results without squeegees or ladders on most jobs.

How do I get a price for my building?

Call us at (415) 975-1522 or send an email. We ask about building height, number of windows or the surface you need cleaned, and access. From there we give you a written quote before any work starts.

Do you do one-time jobs or only recurring service?

Both. We take on one-time cleans and we also work with property owners who want scheduled service. Either way the process is the same, you get a quote first and we confirm the schedule before we show up.
