Commercial Window Cleaning
Commercial window cleaning for low-rise buildings across Northern California and Nevada: storefronts, office windows and interior glass, booked around your hours.
Clear glass, inside and out
Customers size up a business at its front door, often before they reach the counter. Smudged entry glass, a hazy storefront or upper windows streaked with a season of dust tell visitors nobody is looking after the building. Sage Commercial Cleaning provides commercial window cleaning for low-rise buildings across Northern California and Northern Nevada, so the view in and the view out both look the way you want them to.
We clean storefronts, offices and multi-tenant properties throughout the Bay Area, the Sacramento Region, the Central Valley and the Reno and Carson City area. Window service can run as its own visit or fold into the recurring janitorial service you already have with us, so the glass is handled by a team that already knows your building.
Interior glass from the lobby to the conference room
Most of a building’s glass is indoors, and it gathers fingerprints faster than any exterior pane. Crews clean entry doors on both faces, the sidelights beside them and the push bars and handles framing the glass. Lobby windows, stairwell glass and interior transoms get the same streak-free finish.
Glass partitions and conference-room walls are cleaned top to bottom, with marker ghosts, tape marks and handprints lifted off rather than smeared around. In retail stores and dealership showrooms, crews polish the tops and fronts of display cases and glass counters, and the insides too once staff have cleared the shelves, so products show clearly under the store lights.
Exterior windows on one- to three-story buildings
Outside, the work starts at street level. Storefront panes, ground-floor windows and glass vestibules are washed, squeegeed and detailed along the edges. Frames, sills and tracks are wiped in the same pass, so loose grit doesn’t run back onto fresh glass with the next rain or sprinkler cycle.
Second- and third-story windows are reached from the ground. Water-fed poles carry purified water up to the glass and rinse it without spotting, ladders cover windows set back over awnings or planters, and lifts take care of anything a pole can’t reach. Every Sage client receives a certificate of insurance, which property managers usually want on file before a lift rolls onto the lot.
Valley dust, spring pollen and hard-water spotting from irrigation all settle on exterior glass across Northern California and Northern Nevada, and each one gets its own treatment so the panes come out clear rather than cloudy.
Inside the building, crews lay down mats under ladders, keep drips off carpet and hard floors, and wipe up any water at the base of each window before moving on. Blinds and furniture that were moved go back where they were, and the lobby is ready for business when the doors open.
A schedule that fits the building
Storefronts see the most traffic and look their best on a weekly or every-other-week visit. Upper-floor and office windows hold up well on a monthly or quarterly rotation, and interior partitions can join any of those trips. For janitorial clients, the glass work lines up with the nights our crews are already on site.
One-time cleans cover the moments between routine visits: after a tenant improvement or construction project leaves stickers and residue on new glass, ahead of a fresh tenant’s move-in date, or before a property showing or an inspection. Every visit is booked around your business hours, whether that means early morning, evening or weekend, so customers and staff never have to step around a ladder.
Buildings that count on clean glass
Retail stores and strip-center storefronts depend on display windows that sell from the sidewalk. Medical and dental offices want a waiting room that looks as fresh as the exam rooms behind it. Car dealerships need showroom glass clear enough that the inventory inside does the talking.
Office buildings, business parks and apartment communities carry more glass than most owners realize: suite entries, common-area doors, leasing offices and long runs of windows along each floor. Property managers can put the whole site on one plan, with tenant entrances on a tighter rotation than the upper windows.
Gyms with mirrored walls and glass fronts, hotel lobbies, government offices and childcare centers with low windows at a child’s eye level each get a glass plan matched to how the space is used, from fingerprint-heavy doors to the panes a lift reaches once a quarter.
What commercial window cleaning costs in 2026
Going by published 2026 price guides, a ground-level storefront cleaned inside and out runs about $85 to $290 a visit. A one- to three-story office building usually lands between about $275 and $950 a visit. Bay Area glass sits in the upper part of each range, while Central Valley and Northern Nevada properties come in nearer the lower part.
Several things set where a building falls: the number and size of the panes, whether one side or both are cleaned, how high the windows sit and how crews reach them, and whether frames and tracks are detailed. Frequency counts as well, since glass on a regular rotation cleans faster than glass seen once a year. A first visit runs longer when hard-water spots or construction residue have built up, and after-hours timing is priced into the visit.
Getting clear glass on the calendar
A walkthrough lets us count the panes, check access around the building and note any buildup before pricing the work. You receive a written quote listing the glass covered and the visit schedule, and the first clean goes on the calendar at a time that suits your hours.
Tell us which glass matters most to you, from the front entrance to the top-floor windows, and we’ll build the plan around it. Request your window cleaning quote.
A few useful answers
Common questions.
How often should storefront windows be cleaned?
Weekly or every other week keeps a busy storefront bright. Quieter frontages and upper windows stay presentable on a monthly or quarterly visit.
Can window cleaning be added to our janitorial service?
Yes. Glass work joins your existing cleaning schedule, with storefront panes on one rotation and upper windows on another.
How do you reach second- and third-story windows?
From the ground, with water-fed poles and purified water, ladders where they fit, and lifts for windows a pole can’t reach.
Are window frames and tracks cleaned as well?
Yes. Frames, sills and tracks are wiped down along with the glass on each visit, so grit doesn’t drain back onto clean panes.
Can you clean the glass after our build-out wraps up?
Yes. A one-time clean clears paint flecks, sticker residue and construction dust from new glass before move-in, a showing or an inspection.
