Window Cleaning in Worcester, MA
Glass inside and out, screens and storm windows, starting at $250. Estimate on the phone, firm price confirmed on site, and on most jobs the work done that same visit.
At Joslin & Co, we clean windows for homeowners in Worcester, Massachusetts. A residential job covers the glass inside and out, the screens, and storm windows where a house has them, starting at $250. Call with a rough window count and how many units are in the building and we can estimate it on the phone.
Worcester has the largest housing stock of anywhere we work and the highest share of two-to-four unit buildings on our list at 45.8%. Only 30.4% is single-family detached, the lowest of the sixteen towns we cover. That combination is why a Worcester quote usually starts with how many units are in the building rather than how many windows are in the house.
What you get
What a residential window cleaning covers
Here it is as a list rather than buried in a paragraph, so you can hold it up against whatever else you are being quoted.
| Covered by a residential job | What that means |
|---|---|
| Exterior glass | Every pane on the outside of the house |
| Interior glass | Every pane on the inside, done by hand, room by room |
| Screens | Taken out, cleaned, put back |
| Storm windows | Cleaned including the glass behind the storm, as part of the job rather than a separate service |
On a two-family or three-family, that list applies to every unit in the building, and the quote gets built up from unit count rather than treating the place as one house. If you want something looked at that is not on the list, ask on the call and we will tell you straight whether it is part of the job or priced separately.
The one to ask about
Yes, we clean storm windows, including the glass behind them
It is the question that decides whether one quote is comparable to another, so we will answer it first. We clean storm windows, and we clean the glass behind them.
42.8% of Worcester housing predates 1940, one of the highest figures on our list, so storms are common here. Common is not the same as certain. Housing that age has usually been through at least one round of window replacement, so it gets confirmed on site.

A storm sits in front of the primary sash, which puts twice as many glass surfaces in that opening as there appear to be. Cleaning only the outer face leaves three dirty surfaces behind it and the window still looks wrong. Doing it properly means working the storm through its own tracks, cleaning the glass behind it, and putting everything back as it was.
That is real extra labor, which is why storms have to be counted before a price means anything. With us they are part of a residential job rather than an add-on line, but they do affect the number, because they affect how long the job takes. Mention them when you call and we will build them in. Worth asking anyone you ring, in these words: do you clean the storms, and do you clean the glass behind them.
What it costs
Residential window cleaning in Worcester starts at $250
We publish it because knowing the floor tells you whether we are worth a call. $250 is the minimum for a residential job, not an average and not a typical price. What takes a job above it is the list below.
| What moves the price | Why |
|---|---|
| How many units in the building | Three interiors to get into, not one |
| Pane count | A true divided sash is many small panes, not one window |
| Storm windows | Twice the glass surfaces, plus working the storm to reach behind |
| Upper-floor glass | Reaching it from the ground takes different equipment |
| Insides as well as outsides | Interior work means access, moving things, protecting floors |
| Screens | Taken out, cleaned, reinstalled on every operable window |
| Where equipment can stand | Poles and ladders need somewhere level to set up |
| Condition of the glass | Mineral scale or paint is removal work, not cleaning |
Worth knowing before you compare quotes: many modern replacement windows have grids that only look divided. A grille sealed inside the glass, or clipped to the inside face, leaves one flat pane and cleans like plain glass. Real muntins holding twelve separate panes take several times longer. From the sidewalk the two look nearly identical, which is why a phone number is an estimate and the firm price gets confirmed on site.
Most people settle into having it done once or twice a year. Maintenance plans run annual or semi-annual, and glass kept on a schedule never gets back to the state a first clean has to start from.
How it works
One visit, not two
The usual way this goes is that someone comes out to look at your house, gives you a number, and then books a second appointment to do the work. That is two mornings you have to be free for one 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. On a multi-unit building the phone call matters more than usual, because the thing that actually needs scheduling is not the glass, it is getting into the units. Tell us how many are occupied and whether you can give tenants notice, and we can plan it so the whole building gets done in one visit.
| 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. Residential starts at $250 |
| 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 |
You get a message the day before we come, so nobody in the building is surprised by a van in the driveway. The same cleaners come back to the same property next time, which on a three-family is worth more than it sounds. Someone who has been there before knows which unit has the sticking sash and which side of the building the hose bib is on.
Working on Worcester housing
The three-decker city, and what that means for a quote
No town we work in is defined by one housing type the way Worcester is by the two-to-four unit building. 45.8% of the stock sits in one, which is the highest share of the sixteen and well ahead of the 30.4% that is single-family detached.

Three floors, three sets of interiors
That building type creates a specific job. Glass on the first, second and third floors. Three separate interiors to get into if the insides are included. Often three separate households to coordinate with. The window count matters, but the unit count and the occupancy matter more.
Reaching the top floor
Upper glass gets worked from the ground with a water-fed pole, which filters the dissolved minerals out of the water so the glass dries without spotting and without being toweled. On a building of this age the bigger point is that it keeps ladder weight off gutters, siding and roofline. Interiors and close detail stay hand work.
Getting it done in one visit
The thing that decides that is access, not glass. Tell us how many units are occupied and whether tenants can be given notice, and the whole building can usually be planned as a single visit instead of a return trip for whoever was out.
Before you hire anyone
Ask for both policies by name, not just “are you insured”
“Insured” covers two different things, and the one people usually have in mind is not the one that protects them most.
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.
On a two or three floor building, where the glass is nowhere near all at ground level and a ladder can end up over a shared drive, the second policy is the one that matters. If someone uninsured is hurt on your property, your own policy can end up involved.
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 window cleaning in Worcester
How much is window cleaning in Worcester?
Residential window cleaning starts at $250. What takes a job above the minimum is how much glass there is, what is actually in the openings, whether there are storms, whether you want the insides done, and the condition of the glass. Call with a rough window count and we can give you a real number on the phone.
Do you clean storm windows?
Yes, including the glass behind the storm, and it is part of a residential job rather than an add-on line. It is a fair question to put to anyone you call, because it changes what a quote is actually covering.
My windows have small divided panes. Does that cost more?
It depends whether the division is real. A true six-over-six sash is twelve separate panes, each with its own perimeter to detail, and it has to be done by hand. A modern unit with a grille inside the sealed glass, or clipped to the inside face, is a single flat pane and cleans like plain glass. The two look almost the same from the street.
Do you quote a three-decker per unit or per building?
Per building, built up from the units. Three units means three sets of interiors and glass on three floors, so it is not three times a single-family quote and it is not one either. Give us the unit count and whether interiors are included and we can put a number on it.
I own a two-family. Can you do the whole building?
Yes. Give us the unit count and tell us which interiors are included and we can estimate it on the call. On an occupied building, tell us whether you can give tenants notice, because that is what decides whether it all gets done in one visit.
Do I need to be home?
If the insides are part of the job, somebody needs to let us in. You get a message the day before we come either way.
Can you reach third-floor windows?
Yes. Water-fed pole systems reach upper glass from the ground, which also keeps ladders off gutters and siding. Which method gets used depends on the window.
My house is old. Does that mean old windows?
Not necessarily, and it is worth checking before you assume. A house that age has usually been through at least one round of window replacement, and plenty of them have modern units in now. What is in the opening today is what affects the job, not the year the house went up.
Are you insured?
Yes. $1,000,000 in general liability and workers’ compensation, with a certificate available on request. They are separate policies, so ask for both by name, from us and from anyone else you call.
How soon can you do it?
On most jobs we quote and do the work on the same visit, so you are not booking two separate appointments for one job.
How often should I have it done?
Once or twice a year works for most homes. Houses on busy roads, under heavy tree cover, or with sprinklers throwing water onto the glass build up faster and do better on a shorter interval. Maintenance plans run annual or semi-annual.
Will the same people come back next time?
Yes. The same cleaners return to the same property.
