The drive is the job

In Montana, most of what you pay for is the drive

That is not a complaint, it is just arithmetic. This is the fourth largest state in the country with about a million people in it. A service call from Billings to Glendive, or Missoula out to Dillon, is most of a day before anybody picks up a screwdriver.

Which has one useful consequence: the marginal cost of the second repair, and the third, is small. The window you called about and the five others you have been ignoring cost far less done together than they would in separate visits, and the difference is not modest.

So the whole of this page is written around one visit. What we carry so the job finishes first time, what to check before we set off, and how to make a long drive worth both our while.

On the truck

What rides on the truck for window work

A return trip for a forgotten part is a wasted day in this state. Everything here travels as standard.

What we carryWhy it is on board
Sash cord, pulleys and weightsOlder Montana housing in Butte, Helena and Billings still runs on cords and weights. The parts cost almost nothing and they fail predictably.
Balances in several patternsSpiral, block-and-tackle and constant-force, in the common sizes. We carry a spread because identifying the exact one from a phone call is not always possible.
Locks, keepers and tilt latchesThe most common single fault we attend, and the cheapest to fix. Carrying a selection means it gets done today.
Weatherstrip in multiple profilesDifferent ages of window take different sections. In a climate like this it is the highest-return item we fit, so we never want to be short of it.
Crank operators and armsCasement and awning gearboxes strip, and the housing cracks at low temperatures. Replaced as a unit.
Glazing compound, points and beadsSo reglazing and re-bedding can happen on the same visit rather than becoming a second trip.

Make the trip count

Walk round before we set off

Five minutes with a notepad before you ring saves a second visit. Anything you add to the list costs a fraction of what it would as its own call-out.

Try every window, not just the bad one

Open, close and lock each one. In a house of the same age with the same hardware, the fault you noticed is usually present in three or four others at an earlier stage.

Check the locks pull tight

Close each window on a strip of paper. Where it pulls out freely, the lock is not compressing the seal. That is both the rattle and the draught, and it is quick to put right.

Press the sills

Firm thumb pressure along the bottom rail and the sill. Soft or dark timber is the one fault that is getting worse while everything else waits, and it changes what we bring.

Note which ones you never open

Those are the candidates for sealing rather than servicing, and knowing in advance lets us plan the visit sensibly.

Look at the doors and screens too

Same trip, same drive. A door that will not latch and four torn screens cost very little added to a window visit and a great deal as their own.

What Montana does to it

Five forces acting on a Montana window

Not weather in general. Five specific mechanisms, and each one does something different.

Chinook swings

Montana holds the national record for the largest temperature change in twenty-four hours, and the mechanism behind it — a chinook wind coming down off the Rockies — is a normal part of winter along the Front. Materials that expand and contract that fast do not do it evenly, and hardware set for one extreme binds at the other.

Wind, sustained and gusting

Great Falls and the Livingston corridor are among the windiest places in the country, with gusts that regularly reach speeds most states only see in storms. Sustained pressure finds every seal that has stopped compressing, and it works fasteners loose over years.

Cold that changes materials

Montana goes genuinely, seriously cold. Polymer balance shoes, tilt latches and crank housings lose flexibility and snap rather than flex. Most of our hardware failures are reported in the week after a cold snap.

Ultraviolet at elevation

Thinner air and high sun exposure mean stronger ultraviolet than most of the country. It degrades weatherstrip, embrittles vinyl and makes screen mesh split rather than stretch, well inside the lifespans those products were sold with.

Elevation and pressure

Sealed glass units made at one altitude and installed at another are under permanent stress. Across Montana's range of elevations this is a real factor in how long a unit lasts, and it is why capillary tubes exist.

05

By building

The buildings we work in

Montana puts four quite different kinds of building in front of us, and the window in each one wants something different.

Log and timber homes

Log walls settle vertically for years after they go up, and the windows and doors in them need slip space above the frame to allow for it. Where that space was never left, or has been filled with trim and foam over the years, the opening slowly crushes the unit. A door that will not latch in a log home is often the building moving, not the hardware failing.

Ranch and outbuildings

Shops, barns, bunkhouses and equipment buildings with hardware that has to work in weather and gets no attention until it stops. Usually simple assemblies, usually repairable, and usually a long way from anybody who would come out for them.

In-town housing

Billings, Missoula, Butte, Helena and Great Falls hold a great deal of early-century stock — weight-and-pulley sash, putty glazing and original storm windows — plus post-war and modern suburbs where balances and sealed units fail together.

Manufactured homes

Common across rural Montana. Lightweight aluminium or vinyl frames, out-swing doors and sizes that match nothing in a store. We have a separate page for these because the parts and the advice are genuinely different.

Questions

Window repair questions

Do you sell replacement windows?

No, deliberately. It is the whole reason our recommendation about repairing yours carries weight. When replacement genuinely is right, we say so and tell you who to call.

Will you drive out to us?

Yes. That is the business. Tell us where you are and we will plan a route rather than pricing the distance into the job.

My windows are painted shut.

Common in older Montana housing. Scored carefully, they open without damage to the sash, the glazing or the trim.

The sash will not stay up.

A cord has parted or a balance has lost tension. Routine either way, and neither needs a new window.

Our log home windows are binding.

Likely settlement rather than the window. Log walls move vertically for years and the opening needs slip space above the frame. We will tell you if that is what we are looking at.

Several things broke after the cold snap.

That is normal. Polymer hardware goes brittle well below zero and a hard cold snap finds every component that was already marginal.
