Commercial Window Cleaning for Storefronts and Offices

Clean glass is part of how a business presents itself, whether that's a storefront customers walk past every day or an office where clear light matters to the people inside. We handle both, on a schedule that fits how the property actually gets used.

Speaks cleans windows for storefronts, offices, restaurants, and new construction across Woodinville, Bothell, Kirkland, Redmond, and the Eastside. Residential jobs are usually quoted on the spot; commercial jobs are often quoted from photos or a walk-through, depending on the property. A flat commercial roof also fails differently than a house roof (debris clogging drains and side scuppers instead of moss buildup), and we treat that as its own problem, not an extension of residential roof work.

Glass Your Customers Look Through First

Storefront glass takes daily wear a residential window never sees: foot traffic, exhaust, hand marks, and whatever the sidewalk kicks up. It's also the glass your customers look through before they walk in, so streaks and film show up in a way that costs you more than a homeowner would ever notice. We can set up a recurring schedule (weekly, biweekly, or monthly) so it stays clean without you having to remember to call.

Office buildings have their own version of the same problem: exterior grime cutting down the natural light people work under. We quote office jobs from photos or a walk-through and can work around occupied hours. New construction gets quoted as its own job: paint overspray, construction dust, and protective-coating film need more than routine maintenance rates cover.

Commercial flat roofs

A Different Roof, a Different Problem

Most commercial buildings in our service area have flat or low-slope roofs, and the failure mode there isn't moss the way it is on a house: it's debris clogging drains and side scuppers, which backs up water on the roof surface instead of letting it drain.

We check and clear those as part of commercial roof service, treating it as the distinct problem it is rather than applying residential moss logic to a roof that doesn't have that issue. Most commercial accounts run on a recurring schedule rather than a one-time call: monthly, quarterly, or semi-annual, depending on the property and how much exposure the glass gets.

Frequently asked

Straight Answers

The questions we hear most from business owners and property managers, answered straight.

Do you offer recurring commercial service?
Yes: monthly, quarterly, or semi-annual plans, depending on the property and how much exposure the glass gets. Storefronts with heavy foot traffic typically need more frequent service than an office building set back from the street.
Can you quote a commercial job without an in-person visit?
Often, yes, for window cleaning specifically: photos are usually enough for a residential-scale storefront or office building. Larger or more complex properties, and anything involving roof work, typically need a walk-through first.
Do you clean commercial roofs the same way as residential roofs?
No. Most commercial buildings have flat or low-slope roofs, where the problem is debris clogging drains and scuppers rather than moss. We check and clear those as their own service, not an extension of our residential moss removal work.
What does commercial window cleaning cost?
Commercial pricing depends on the property: square footage, glass access, and whether it's a one-time clean or a recurring schedule. See our Pricing page for how we approach it, and call for a quote specific to your building.
