Condo, Apartment, and Mid-Rise Window Cleaning in San Francisco
San Francisco buildings present a specific set of challenges for window cleaning. Older Victorian and Edwardian facades, narrow alleyways, Juliet balconies, interior-facing courtyard windows, and multi-unit buildings with no central cleaning schedule all make it harder for residents and property managers to keep glass looking clean.

For condo and apartment buildings, the challenge is compounded by the number of units involved. Each window faces a slightly different direction, gets a different amount of direct exposure to fog and salt air, and may have a different level of buildup depending on how long the building has gone without a professional cleaning. Ground-floor units near traffic collect exhaust film faster. Upper-floor units facing the water or the prevailing wind direction accumulate salt deposits more quickly. A thorough cleaning addresses all of it in a single organized visit.
Property managers and HOAs often find it easier to schedule one professional cleaning for the entire building than to manage multiple individual requests from unit owners. We work with building managers to coordinate access, minimize disruption to tenants, and complete the job efficiently. Individual condo owners are equally welcome to call and arrange service for their own unit.
Dan Mount Cleaning Services handles condo, apartment, and mid-rise window cleaning up to 4 stories in San Francisco. Whether you manage a six-unit building in the Mission or own a condo in a larger complex in Nob Hill or the Outer Sunset, we work around your building layout and your tenants' schedules.

Our Process
Walk the building first
Before we touch a window, we look at the layout, access points, and anything unusual, like security grilles, painted sills, or damaged seals, so there are no surprises during the job. For multi-unit buildings, we also note which units require interior access and coordinate that with the building manager in advance.
Protect the surroundings
We lay drop cloths or absorbent mats where needed. Water runoff is managed carefully, especially in buildings with shared lobbies or interior courtyards. We do not leave puddles or water trails in common areas.
Clean exterior glass first
We use water-fed pole systems with deionized water on exterior surfaces. This removes mineral deposits, salt film from coastal fog, and general grime without leaving residue behind. Deionized water dries clear because the minerals that cause spots have been filtered out before the water reaches the glass.
Clean interior glass by hand
Interior surfaces get professional-grade squeegee work for a completely clear finish. Frames and sills are wiped as we go. We work carefully around furniture and personal belongings in occupied units.
Final inspection
We check every pane before we leave. If something looks off, we go back to it. We do not pack up until the glass looks the way it should.
For buildings with specific access limitations or HOA requirements, let us know when you call and we will work around them.
Why Consistent Cleaning Matters for Multi-Unit Buildings
In a single-family home, dirty windows are a cosmetic issue. In a condo or apartment building, they affect how the entire property presents to prospective tenants, buyers, and visitors. A building where the exterior glass is clean looks cared for. One where the windows have gone gray from mineral buildup and salt film looks neglected, even if everything else is in good shape.
For buildings being listed for sale or going back on the rental market, clean windows make a measurable difference in first impressions. For buildings where tenants have been in place for a while, a professional cleaning is one of the more visible improvements a property manager can make without a significant investment.
San Francisco's marine layer and coastal fog deposit a fine salt film on exterior glass over time. On a building with multiple units, that buildup can become noticeable faster than it would on a single-family home.

Signs You Need It
Some of these are obvious. Some property managers and homeowners put it off longer than they realize.
- Glass looks hazy or filmed even on clear days
- Salt residue or mineral spotting from fog and rain has built up on exterior panes
- Tenants are noticing dirty windows or obstructed views
- Tracks and sills have visible debris or grime
- The building is going on the rental market or being listed for sale
- It has been more than a year since the last professional cleaning
- Ground-floor windows near the street have a visible film from exhaust and foot traffic
What It Costs
There is no flat rate for condo and mid-rise window cleaning because the price depends on too many variables: the number of units, how many windows per unit, whether we are cleaning interior and exterior or exterior only, building access, and the current condition of the glass.
A six-unit building where the exterior glass is in decent shape will cost less than a twelve-unit building where the windows have not been professionally cleaned in several years and need extra time to address mineral buildup. We will tell you what we are looking at during the walk-through so the quote reflects the actual job.
We give you a written quote before any work starts. No surprises on the invoice.
The best way to get an accurate number is to call us at (415) 975-1522 or send a message describing your building. Tell us the number of stories, approximate unit count, and whether you need interior cleaning included. We will give you a clear quote from there.
For context on our general window cleaning work and the systems we use, visit the main window cleaning page. If your building also needs commercial window cleaning for common areas or ground-floor retail, we can quote that at the same time.
We serve property managers, HOAs, building owners, and individual condo owners throughout San Francisco. If you are not sure whether your building qualifies or falls within our scope, just ask. We will tell you straight.
Frequently Asked Questions
Do you clean both interior and exterior windows in a condo building?
Yes. We can clean interior and exterior glass, or exterior only if that is what you need. Most clients in multi-unit buildings want both sides done. We clean frames, sills, and tracks as part of the job.
How do you handle access in a building with multiple units and different tenant schedules?
We work with you and the property manager to coordinate access. For exterior-only work, tenant cooperation is usually not needed. For interior cleaning, we typically schedule unit by unit or work with a coordinator to arrange access in advance.
What does 'up to 4 stories' mean in practice?
We use water-fed pole systems and ladders to safely reach windows on buildings up to 4 stories. If your building is taller than that, we can assess it, but our standard scope covers 4 stories and under.
Can you work with our HOA or property management company directly?
Yes. We are used to coordinating with property managers and HOA boards. We can send quotes, scheduling details, and job summaries to whoever handles the building's vendors.
What makes deionized water better for exterior glass?
Tap water contains dissolved minerals that leave spots on glass as the water dries. Deionized water has those minerals removed, so when it dries on the glass it leaves nothing behind. That is how we get a streak-free finish on exterior windows without wiping every pane by hand.
