Commercial Window Cleaning in Lowell, 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 Lowell, 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.

There are really two commercial services hiding under one name. One is street-level frontage, which is quick, repeats well, and works best on a standing interval, anything from weekly to quarterly depending on the business. The other is a building, which is a project rather than a visit and gets quoted as one. Almost every question we ask on the first call is aimed at working out which of the two you need.

What you get

What a commercial job covers

Written as a list rather than a paragraph, so it is easy to compare against anyone else you are talking to.

CoveredDetail
Exterior glassStorefront, entrance glass and windows up to five stories
Interior glassCleaned by hand, arranged around your opening hours
ScreensWhere a building has them
Storm windowsCleaned including the glass behind the storm, which matters on older mixed-use buildings

Anything on the building that is not on that list, raise it while we are on the phone. If it is a separate service we will say so then, which is a better time to find out than when the invoice arrives.

What a property manager checks

The paperwork, before the glass

Every business that buys a recurring service checks the same handful of things first. Rather than wait to be asked, here they are with the answers attached.

What you needWhat we have
Certificate of insuranceAvailable on request, for your file
General liability$1,000,000
Workers’ compensationCarried. Separate policy from liability, and the one that matters if somebody is hurt on your property
Uniformed techniciansYes. Your staff and customers can tell who we are
Invoicing termsNet-30
A real office to call61 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 stop at five stories. If your building goes past that we will say so immediately, because wasting a site visit to arrive at the same answer helps nobody.

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 Lowell 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 itWhy
How much frontage there isThe main driver on street-level glass
Inside as well as outsideInterior work has to fit your opening hours
How often we comeGlass on a schedule takes less time per visit than glass left for a year
Ground level or above itOnce glass is off the ground it stops being storefront work
Condition of the glassMineral scale or construction residue is removal work, not cleaning
Number of sitesSeveral 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

The usual way this goes is that somebody comes out to look, gives you a number, and then books a second appointment to do the work. For a business that is two interruptions instead of one.

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.

StepWhat happens
1. You call or send the formWe go through what is there before anyone gets in a van
2. We give you an estimate on the callA real number to work from. Storefront starts at $50
3. We come out and confirm the priceLooking at the actual glass, before anything starts
4. We do the job that visitOn most jobs the work happens the same time we come out

We message the day before. Crews stay with the same site rather than rotating, so by the second or third visit they know your hours, how to get in, and which entrance not to block.

How often

Storefront on a route, multi-story as a project

How often makes sense depends on what the glass takes and who sees it, and in practice that lands somewhere between weekly and quarterly.

Type of glassTypical rhythmWhy
Street-level retail frontageWeekly to monthlyIt is the first thing a customer sees and it gets handled all day
Office and professional suitesMonthly to quarterlyLess traffic on the glass, and appearance still matters to visitors
Multi-story building glassInfrequent, project-basedBigger 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.

We come on the agreed interval and invoice net-30, so it goes through accounts payable like any other supplier.

Working in Lowell

The highest share of larger buildings we work in, and where that stops

Lowell has the highest share of buildings with five units or more of any town on our list at 26.3%, plus another 37.3% in two-to-four unit buildings. Close to two thirds of the housing is multi-family.

Street-level glass. Quick per visit, which is why it suits a standing schedule.

That makes managed residential property a real commercial segment here rather than an occasional job. It also runs straight into our ceiling, so it is worth stating plainly: we work buildings up to five stories. Inside that we are set up and insured for the work. Above it we are not the right company, and you will hear that on the phone rather than after we have driven out.

Street-level commercial is the other half. Frontage, entrance glass and professional suites, quick per visit, best arranged as a standing schedule at whatever interval suits the business.

Before you hire anyone

Ask for both policies by name, not just “are you insured”

“Insured” covers two different things, and for a business the distinction is the one your own policy cares 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 building and its glass are covered by general liability. The person up the ladder is covered by workers’ compensation. Where a contractor carries no second policy and somebody is injured on your premises, the exposure does not simply stay with them. That gap is common enough to be worth asking about directly.

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 Lowell

How much is commercial window cleaning in Lowell?

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.
