A clean pane over a dirty sill doesn’t stay clean for long. That’s why our commercial window cleaning covers the whole window system: glass, frames, sills, and tracks. We clean office buildings, schools, medical facilities, and storefront glass across Massachusetts, Connecticut, and Rhode Island.
Interior glass gets scrubber-and-squeegee work with drop cloths under every pane. Exterior glass up to low-rise height gets water-fed poles worked from the ground, no ladders on your facade, no lift in your parking lot. What we quote, we clean, and what we can’t reach, we tell you.
Service runs month-to-month with no contract. Book window cleaning standalone on a monthly or quarterly cadence, or fold it into an existing janitorial program under one invoice. Either way, see how no-contract commercial cleaning works before you commit to anything.

Crews work in two passes. Inside: partition glass, conference-room walls, lobby panels, entry doors, and display glass, microfiber scrubbers and squeegees, nothing dripping on the desks below. Outside: water-fed poles reach low-rise exterior glass from the ground, rinsing with purified water that dries without spotting.
Cadence is set per building, monthly, quarterly, or twice a year, and adjusted as seasons change the glass. First visits often need a restoration pass, hard-water spotting and label adhesive take extra dwell time, before the maintenance schedule starts. Frames, sills, and tracks get vacuumed and wiped every visit; skip them and the next rain streaks the pane from the top down.

We walk your building and count what actually needs cleaning: window lines, partition glass, entry doors, exterior stories. We note water access for the pole system, crew parking, and any panes with hard-water staining or construction residue that need extra treatment.
Within 48 hours you get a written quote priced per visit: interior glass, exterior glass, frames and tracks, itemized. Choose interior-only, exterior-only, or both on different cadences. The number covers labor, equipment, and purified water.
We book the first visit where it fits your building, an early slot before doors open or an evening after close. The crew arrives with everything on the truck: poles, purified-water tank, squeegees, drop cloths for interior rooms. The same dedicated crew handles your building on every visit.
Each visit follows the same route: exterior glass first, then interior, then frames, sills, and tracks. The crew lead checks the glass in daylight-facing rooms before leaving. Streaks show at certain angles. We’d rather catch them than have you report them. You sign off; we log the visit.
Every quarter we review the program with you. Spring pollen, winter road-salt film, and construction next door all change how fast glass loads up. We adjust frequency, add or drop exterior passes, and reprice only what changed. Month-to-month means the plan can move when your building does.
Most low-rise commercial window washing doesn't need a lift. It needs the right pole. Our water-fed systems push purified, deionized water up a telescoping pole to a soft brush head that scrubs and rinses the glass. Because the water carries no dissolved minerals, it dries spot-free with no squeegee pass. Nothing leans against your facade, nothing blocks your parking lot, and nobody stages equipment on your roof. One limit, stated plainly: Modular doesn't do high-rise rope or stage work. If your building rises past pole reach, we say so at the walkthrough and quote the floors we can clean well. For the surfaces around the glass, entryway concrete, siding, awnings, pair window service with commercial pressure washing on the same visit schedule.

Interior glass is where office window cleaning turns disruptive if it's handled carelessly. Our crews clean partition glass, conference-room walls, lobby panels, and entry doors in zones, so no department loses its meeting space for a morning. Drop cloths and careful overspray control keep desks, monitors, and carpet dry. A common split is interior glass monthly and exterior quarterly. We'll recommend one based on your foot traffic and your street. Already running a cleaning program with us? Window service folds into your office cleaning or janitorial schedule: one point of contact, one invoice, one crew standard. Our office cleaning checklist shows where glass fits inside a full program.
Building window cleaning changes with the building, so the schedule should too. Schools get exterior passes during vacation weeks and interior glass after dismissal, not while students fill the hallways. Medical offices get first slots of the morning, before patients arrive, with crews briefed on corridor access and privacy. Storefront glass on office and mixed-use buildings gets its street-facing sides cleaned first, because that's the glass your tenants' customers judge from the sidewalk. One boundary we hold: we clean storefront glass as part of a commercial building, but we don't take full-facility retail work. Start at the services overview to see how window cleaning pairs with the rest of the lineup. Or check where we work across Massachusetts, Connecticut, and Rhode Island.
What does commercial window cleaning cost? It depends on the glass, which is why we price per visit from a walkthrough count, not a flat rate sheet. Five factors move the number: pane count and stories, interior versus exterior scope, frame and sill condition, access around the building, and any first-visit restoration work. Hard-water spotting and construction residue take extra dwell time to lift; on a new build, that first pass often runs alongside post-construction cleaning. Within 48 hours you get a written quote, itemized line by line, so you can drop or add scope before committing. Because water-fed poles work from the ground, there's no lift rental built into the price. And service runs month-to-month with no annual commitment. The quote covers visits, not a year.
There's no single right answer. Cadence follows the building. For offices, a common split is interior glass monthly and exterior passes quarterly. Schools book exterior work around vacation weeks, when crews can stage freely. Medical buildings take early-morning slots before the first patient arrives. Street-facing storefront glass loads up fastest and usually earns the shortest cycle. Trade association ISSA treats glass care as part of routine building maintenance. The question is how often, not whether. Seasons move the answer too: spring pollen, winter road-salt film, and construction next door all shorten the cycle. That's what the quarterly review is for. We adjust frequency without repricing the whole program. Around Hartford and New Haven office parks, where demand for window service runs strongest, quarterly exterior passes are a practical starting point. You can also fold window cadence into a broader commercial cleaning program under one invoice.
Streaked glass is the first thing a visitor sees and the last thing anyone budgets for. One walkthrough fixes that. We count the panes, note the problem glass, and price the whole system.
Quotes are free and written. No contract, month-to-month from the first visit. Call (508) 658-0303 or start with a no-obligation estimate.
With water-fed poles that reach upper-story glass on low-rise buildings from the ground, using purified water that dries spot-free. We don’t do high-rise rope or stage work, and we say so up front. If part of your building runs taller than pole reach, we quote the floors we can clean and tell you which ones we can’t.
Every visit includes frames, sills, and tracks, vacuumed first, then wiped. Skipping them is how glass gets dirty again fast: wind pulls grit off dirty sills straight onto the pane. Partition glass, entry doors, and interior lobby panels are part of the standard scope too, not add-ons.
That’s how most of our window work runs. Offices get evening or early-morning visits, medical buildings get slots before the first patient, and schools get vacation weeks or after-dismissal blocks. Crews work Monday through Friday 6 AM to 9 PM and Saturday mornings, so there’s usually a window that avoids yours.
Yes. You’re never locked into an annual term. Window service stays month-to-month, and canceling takes 30 days written notice. You can start with a single interior-and-exterior clean, judge the glass in afternoon light, then set a recurring cadence, or read our customer reviews first. We earn the next visit with the current one, not with an agreement you can’t exit.
