Where We Work

Southern New Hampshire and north-central Massachusetts, from New Ipswich.

Joslin & Co works out of New Ipswich, New Hampshire. The town sits close enough to the Massachusetts line that our service area covers both states, which is unusual in this trade, where most companies work one side of the border or the other.

Why the local part matters

New England housing stock changes the job

This is not a market where every house has large modern sashes, and that has practical consequences for what window cleaning costs and how long it takes.

Storm windows

A great deal of the housing stock here has exterior storm windows. They add glass surfaces, and the storm has to be worked on to reach the sash behind it. Some companies decline that work outright. We clean storm windows.

Divided lites and grids

A six-over-six colonial sash is twelve small panes, each with its own perimeter to detail around. It takes several times longer than a modern picture window the same size, and it needs hand work rather than a pole.

Mill buildings

The commercial stock in this region includes a lot of converted mill buildings. Large industrial sash, deep sills and original frames are nothing like a modern curtain wall, and they are not something to price from a photograph.

Winter and pollen

Road salt through the winter and heavy pollen in spring are the two things that drive scheduling here. Spring and fall are the natural windows, and booking just after the heaviest pollen passes gives a noticeably better result than booking during it.

The two-state footprint

Why working both sides of the border is unusual here

Most window cleaning companies in this region work one state or the other. The Massachusetts firms stop at the state line; the New Hampshire ones rarely come south of it. New Ipswich sits close enough to the border that both sides are a normal working distance.

Southern New Hampshire

The Monadnock region, the Nashua corridor, and up through Manchester and Concord. Older housing stock, a great many storm windows, and a lot of colonial sashes with divided lites. All of which change what the job takes and how it has to be worked.

North-central Massachusetts

Worcester, the Lowell and Chelmsford corridor, and the towns along Route 2. More converted mill buildings and commercial frontage, and a denser storefront market where recurring schedules make more sense than one-off cleans.

What does that mean practically

If you have properties on both sides of the line, and plenty of property managers in this area do, it is the same company, the same crew, and one invoice rather than coordinating two separate vendors.

Before you call anyone

Two questions worth asking any window cleaner in this region

Whoever you end up hiring, these two will tell you most of what you need to know.

1. Do you clean storm windows?

A great deal of the housing here has them, and not every company will take that work on. Some say so plainly on their own websites. If your house has storm damage and the company does not handle it, you are paying for a partial clean. We clean storm windows.

2. Do you carry workers’ compensation, not just liability?

These are different policies covering different things. General liability covers damage to your property. Workers’ compensation covers the person doing the work. If an uninsured cleaner is injured on your property, that claim can reach your own policy. Plenty of small operations in this trade carry the first and skip the second, because compensation coverage is expensive and often not legally required at a small headcount.

Joslin & Co carries $1,000,000 in general liability and workers’ compensation, with a certificate of insurance available on request.

What the service involves

The same four services everywhere we work

Wherever the property is, the work and the standard are the same.

Residential window cleaning

Interior glass, exterior glass, storm windows, and screens. Cleaning once or twice a year suits most houses. Exterior glass is cleaned with water-fed pole systems or by hand, depending on the window.

Commercial window cleaning

Storefront glass on a recurring cleaning schedule, and building glass up to five stories. Certificate of insurance on request, workers’ compensation, uniformed technicians, and net-30.

Post construction window cleaning

Cured paint, mortar, adhesive and construction debris bonded to glass. Steel wool and razor work rather than washing, with a glass scratch liability waiver.

Hard water window restoration

Mineral scale is bonded to the glass surface that cleaning will not lift. Polishing and abrasive treatment are quoted after we look at the glass.

How the glass gets cleaned

A water-fed pole system filters water to strip the dissolved minerals that cause spotting, so glass rinses and dries without toweling. It also reaches upper story glass from the ground, which keeps ladders off gutters and siding. Ground-floor glass, divided lites, and interior glass are cleaned by hand because a pole is the wrong tool for detailed window work.

How often to clean

Cleaning frequency by property type

The right interval is the one where the glass never actually looks dirty. That is usually cheaper across a year than letting windows get bad and paying for heavier cleaning.

PropertyTypical cleaning interval
Most housesOnce or twice a year
Houses on a maintenance intervalAnnual or semi-annual
Retail and storefront glassAs often as weekly
Restaurants and food serviceWeekly to monthly
Offices and low-rise buildingsQuarterly to semi-annual
Building common areas and lobbiesQuarterly to semi-annual
After a build or renovationOnce, as post construction cleaning

Glass exposed to irrigation overspray, heavy tree cover or a busy road benefits from more frequent cleaning, because the material landing on it is the kind that bonds to glass if it is left.
