Commercial Window Cleaning · Manchester, NH
Commercial Window Cleaning in Manchester, NH
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 Manchester, New Hampshire. 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.
Two very different jobs share the name commercial window cleaning. Frontage at street level is quick per visit and rewards a repeating schedule, weekly at one end and quarterly at the other. A whole building is not that. It is a project, it happens far less often, and the number comes per building rather than per visit. Sorting which one you are is the first thing we do on the phone.
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
Any business buying a recurring service has a short list it runs through before the work is worth discussing. Here is ours, answered up front rather than after you ask.
| 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 |
Those six are the reason a facilities manager can sign off on a small company instead of defaulting to a national one. The pair that matters most is general liability and workers’ compensation, which are separate policies. It is worth asking anyone you are considering for both by name rather than asking whether they are insured.
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.
That limit is stated deliberately. Once glass is high enough, the difference between contractors is no longer finish, it is safety, and a firm that accepts every building is telling you something about how it makes decisions. Up to five stories we are properly set up and properly insured. Past it we are not, so we do not pretend otherwise.
What it costs
Storefront window cleaning in Manchester starts at $50 a visit
Publishing a figure at all is unusual in this trade, which is most of why we do it. Read it precisely: $50 is the entry point for a storefront visit, not a typical spend and not a number for a whole building.
| 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 |
Multi-story buildings are 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. Call and we will tell you what we need to know.
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.
One visit covers it. We estimate over the phone, confirm the firm price on site, and on most jobs clean during that same visit. Opening hours come first in the conversation, because work that gets in the way of business is a poor trade for clean glass.
| 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 |
A standing schedule is worth more than the discount on it. Glass kept on a route never reaches the state a first clean has to start from, so each visit is quicker, and nobody at your end has to remember to book it.
Visits happen on the agreed interval and the invoice follows on net-30 terms, so it clears accounts payable the same way every other supplier does.
Working in Manchester
Portfolio work and street-level frontage, in the second largest stock we cover
Manchester is the second largest housing stock on our list and one of the most stacked. 36.8% sits in buildings of two to four units and another 25.4% in buildings of five or more, against 36.7% single-family detached.

For commercial that means two distinct customers. Property owners and managers running multiple residential buildings, who need scheduling, invoicing and insurance paperwork rather than a one-off clean. And street-level businesses wanting frontage kept presentable on a route.
Both are served the same way and both stop at the same place: five stories. If a building is taller than that we will say so on the first call rather than after a site visit, because height is where this trade gets genuinely dangerous and a company that quotes anything is telling you something.
Before you hire anyone
Ask for both policies by name, not just “are you insured”
The word insured is doing two jobs, and for a business the difference between them is what your own policy ends up caring about.
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.
The glass and the building are covered by general liability. The person on the ladder is covered by workers’ compensation. If an uninsured contractor is hurt on your premises, that exposure can land on you. It is the single most common gap in this trade and it is worth one direct question.
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 Manchester
How much is commercial window cleaning in Manchester?
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.
