Commercial Window Cleaning in Marlborough, MA
Storefront glass from $50, on whatever schedule suits the business. Buildings up to five stories. COI, workers’ compensation and net-30 invoicing.
At Joslin & Co, we clean commercial glass for businesses and property owners in Marlborough, Massachusetts. Storefront window cleaning starts at $50 per visit, we work buildings up to five stories, and we invoice net-30. Call and we can put a number on a storefront on the phone.
Commercial window cleaning divides into two jobs that have almost nothing in common. Storefront and street-level glass is fast, repeatable and suits a standing schedule, weekly for some businesses and monthly or quarterly for others. Multi-story work is a project: bigger, less frequent, and quoted per building rather than per visit. Telling us which one you are is the whole first minute of the call.
What you get
What a commercial job covers
Set out plainly so you can hold it against another quote.
| Covered | Detail |
|---|---|
| Exterior glass | Storefront, entrance glass and windows up to five stories |
| Interior glass | Cleaned by hand, arranged around your opening hours |
| Screens | Where a building has them |
| Storm windows | Cleaned including the glass behind the storm, which matters on older mixed-use buildings |
If there is something on the building you want looked at that is not on that list, ask on the call. We would rather tell you it is a separate service than have it turn up as a line on an invoice.
What a property manager checks
The paperwork, before the glass
Before a facilities manager can even think about the glass, there is a short compliance list to get through. We would rather publish our answers than make you extract them one email at a time.
| What you need | What we have |
|---|---|
| Certificate of insurance | Available on request, for your file |
| General liability | $1,000,000 |
| Workers’ compensation | Carried. Separate policy from liability, and the one that matters if somebody is hurt on your property |
| Uniformed technicians | Yes. Your staff and customers can tell who we are |
| Invoicing terms | Net-30 |
| A real office to call | 61 Appleton Rd Unit 8, New Ipswich, NH 03071, and (978) 340-3890 reaches a person |
That list is what makes a small operator approvable rather than a risk. Note especially that general liability and workers’ compensation are two different policies. Asking a contractor whether they are insured gets you a yes either way, so ask for both by name.
Where we stop
Five stories, and we will say so if your building is taller
We work up to five stories and no higher. A taller building is not our job, and you will hear that on the phone rather than after somebody has driven out to look at it.
It is worth being blunt about that, because height is where commercial window cleaning gets genuinely dangerous and where the gap between companies stops being about finish quality. A firm that will quote anything is telling you something. Inside five stories we are set up for the work and insured for it, which is the honest limit of what we should be taking on.
What it costs
Storefront window cleaning in Marlborough starts at $50 a visit
That number is on the page because a business deciding whether to spend a phone call on us should not have to guess. Be clear what it is, though: $50 is where a storefront visit starts. It is not an average and it is not a building price.
| What moves it | Why |
|---|---|
| How much frontage there is | The main driver on street-level glass |
| Inside as well as outside | Interior work has to fit your opening hours |
| How often we come | Glass on a schedule takes less time per visit than glass left for a year |
| Ground level or above it | Once glass is off the ground it stops being storefront work |
| Condition of the glass | Mineral scale or construction residue is removal work, not cleaning |
| Number of sites | Several locations on one route are quoted differently from one |
For a building rather than a frontage, the quote is per building. There is no honest starting price for that work because the variables swamp it, so we ask questions first and give a figure after.
How it works
One visit, not two
Normally this runs as two visits: one to look and quote, another to actually clean. For a business that is two separate interruptions to the working day for a single job.
We do it in one. You get an estimate on the phone, we confirm the firm price when we see the glass, and on most jobs the work happens on that same visit. For commercial we also want to know your opening hours before anything else, because the point of the job is that it does not get in the way of trading.
| Step | What happens |
|---|---|
| 1. You call or send the form | We go through what is there before anyone gets in a van |
| 2. We give you an estimate on the call | A real number to work from. Storefront starts at $50 |
| 3. We come out and confirm the price | Looking at the actual glass, before anything starts |
| 4. We do the job that visit | On most jobs the work happens the same time we come out |
There is a message the day before each visit. And the same cleaners return to the same site, which is where most of the benefit of a recurring arrangement actually sits. They already know the hours, the access, and the door that has to stay clear when a delivery lands.
How often
Storefront on a route, multi-story as a project
Commercial frequency runs from weekly to quarterly depending on what the glass is doing and who is looking at it.
| Type of glass | Typical rhythm | Why |
|---|---|---|
| Street-level retail frontage | Weekly to monthly | It is the first thing a customer sees and it gets handled all day |
| Office and professional suites | Monthly to quarterly | Less traffic on the glass, and appearance still matters to visitors |
| Multi-story building glass | Infrequent, project-based | Bigger job, quoted per building rather than per visit |
Recurring work pays off twice. Maintained glass takes less time per visit than glass left for a year, and the arrangement runs itself, which removes the part businesses actually find annoying: remembering to call.
The schedule runs without prompting and billing is net-30, which keeps it inside the process your accounts team already uses.
Working in Marlborough
Larger buildings, and the five-story line
Marlborough carries one of the higher shares of larger apartment buildings we work in, 24.2% in buildings of five units or more, alongside 43.6% single-family detached.

Larger buildings mean two things we should be straight about. Managed property is a genuine commercial customer here, with the scheduling and paperwork that comes with it. And our ceiling is five stories. If a building goes above that we are not the right company and we will tell you on the first call.
Inside that limit the work is quoted per building rather than from a starting price, because the variables are too wide for a number to mean anything before we have seen it. Storefront and street-level glass is different: that starts at $50 a visit.
Before you hire anyone
Ask for both policies by name, not just “are you insured”
There are two policies behind the word insured, and only one of them is really about protecting you.
General liability pays for damage to your property. Workers’ compensation pays for the person doing the work if they are hurt while they are there. Two separate policies, and a company can carry one without the other.
Damage to the property is general liability. Injury to the worker is workers’ compensation. If the contractor on your premises has only the first and somebody gets hurt, that can come back to you. It is the most frequent gap in this trade, and one question closes it.
We carry both. $1,000,000 in general liability and workers’ compensation, and a certificate of insurance is available on request. Ask us for it, and ask everyone else for it too.

Questions
Common questions about commercial window cleaning in Marlborough
How much is commercial window cleaning in Marlborough?
Storefront window cleaning starts at $50 a visit. What moves it is how much frontage there is, whether you want the inside done, how often we come, and the condition of the glass. Multi-story buildings are quoted per building rather than from a starting price.
How tall a building can you do?
Five stories. If yours is taller we will say so on the first call rather than after a site visit.
Can you work outside our opening hours?
Tell us your hours on the call and we will build the visit around them. For retail frontage the usual answer is before opening. It is the first thing we ask about on commercial work.
Do you invoice, or do you want paying on the day?
We invoice on net-30 terms, so it goes through your accounts payable like any other supplier.
Can we get a certificate of insurance?
Yes, on request, for your file. $1,000,000 general liability plus workers’ compensation. They are separate policies and it is worth asking any contractor for both by name.
How often should storefront glass be done?
Weekly to monthly for street-level retail, monthly to quarterly for offices and professional suites. Glass kept on a schedule is quicker per visit than glass left for a year, so the interval partly pays for itself.
Do you do more than one location?
Yes. Several sites on one route get quoted differently from a single location, so tell us how many and roughly where on the first call.
Will it be the same crew each time?
Yes. The same cleaners come back to the same site, which on a recurring schedule means they already know your access and your hours.
The glass is stained and cleaning has not fixed it.
Then it is probably mineral scale rather than dirt, which needs polishing rather than washing, or construction residue left bonded to the surface. Both are separate services and both are quoted after we have seen it.
