Double‑Hung Window Installation

Exact Carpentry – Launceston • West Tamar • Northern Midlands

Double‑hung windows are one of those designs that have been around forever and for good reason. They open from the top, they open from the bottom, they let warm air escape while cool air comes in, and they suit almost every style of Tasmanian home, from old weatherboard cottages to modern builds trying to keep a bit of character.

But here’s the part most people don’t realise:

A double‑hung window is only as good as the balance system behind it.

If the weights or springs aren’t set right, the sash will slam shut. If the frame has moved, the sashes will rub. If the jambs aren’t straight, the reveals will look uneven. If the sill isn’t level, the bottom sash will never seal properly. And if the house has shifted which Tasmanian homes love to do the whole thing will tell you every time you try to open it.

Installing a double‑hung window isn’t just “putting in a window”. It’s tuning two moving sashes inside a frame that’s already lived a long life.

Where a Double‑Hung Window Installation Really Starts

Before the new window even comes out of the packaging, we look at the opening. A proper look not a quick glance.

Double‑hung windows rely on:

  • Straight jambs
  • A level sill
  • A square frame
  • Smooth sash channels
  • Balanced weights or springs
  • A latch that meets perfectly

If any of these are out, the window will fight you.

We check:

  • The condition of the old frame
  • The movement of the house
  • The alignment of the sill
  • The straightness of the jambs
  • The exposure to wind and weather
  • The moisture around the opening
  • The condition of the cladding or brickwork

A double‑hung window won’t hide any of this. If the opening isn’t right, the window won’t be right.

The Window Itself – Timber, Aluminium, or Double‑Glazed

Double‑hung windows come in all types:

  • Timber double‑hung windows
  • Aluminium double‑hung windows
  • Double‑glazed double‑hung windows
  • Counterweight systems
  • Spring‑balance systems
  • Custom‑sized double‑hung windows

Each one behaves differently. Each one has its own weight, its own balance system, its own sealing, its own hardware.

But the principle is always the same:

A double‑hung window should move smoothly and stay exactly where you put it.

No slamming. No sticking. No rattling. No sagging. No gaps.

What Double‑Hung Window Installation Costs in Tasmania

Most installations fall between:

  • $480 – $2,200 (window + installation)
  • $300 – $750 (installation only, depending on frame work)

The price depends on:

  • The size of the window
  • The type of glazing
  • Whether the frame needs repair
  • Whether the sill needs levelling
  • The type of balance system
  • Whether the opening needs trimming or packing

Double‑hung windows look traditional. They’re not simple. They’re a balance‑and‑alignment job.

What We See Most Often in Tasmanian Homes

Double‑hung windows fail for predictable reasons:

  • Weights or springs that have worn out
  • Sashes that slam shut
  • Frames that have moved
  • Sashes that rub
  • Latches that never line up
  • Draughts creeping in
  • Water getting in around the sill
  • Windows that won’t stay open
  • Windows that rattle in the wind

A new window won’t fix these unless the opening is corrected. That’s where the real work is.

The Moment the Window Finally Moves Cleanly

There’s a moment in every installation where the window stops arguing. Both sashes move smoothly. They stay exactly where you put them. The seals sit tight. The latch meets perfectly. Nothing rattles. Nothing binds. The window feels like it belongs there.

That’s the moment we aim for.
