The Prep

It’s common for older New Zealand homes to develop the odd patch of window rot. Shady sides of the house, overhanging trees, and years of weather exposure can all take their toll especially on window sills and lower frames. But here’s the good news a rotten section doesn’t automatically mean you need a whole new window.

In many cases, a targeted repair is all that’s required to restore strength, appearance, and longevity.

Cutting out the rot

When rot appears in a small section of a sill or frame, we can cut out the damaged timber and replace it with new, hard-wearing timber. This approach avoids the cost and disruption of manufacturing and installing an entirely new window.

When done properly with quality timber and a durable resin over the top you’ll get the long-term performance you’re looking for without the unnecessary expense.

Repairing in place offers several advantages:

  • Less disruption: No need to remove interior gib or window architraves.
  • Cost-effective: You avoid the price of a full window replacement.
  • Ideal for tricky locations: High or hard-to-reach windows can be repaired safely without major dismantling.
  • Faster turnaround: Repairs are typically completed far quicker than full replacements.

A Smart, Sustainable Solution

By repairing rather than replacing, you’re not only saving money you’re also extending the life of your existing timber joinery. Many older homes were built with beautiful, dense native timbers that are well worth preserving wherever possible.

A well-executed repair blends seamlessly with the original window and provides the durability you need for years to come.

the ravages of time:

Over time, old steel window hinges can rust and seize. When a window hasn’t been opened for a while, the hinge can even pop apart, which is often why some windows become difficult to close.

At Market Ready, we often replace these worn steel hinges with new stainless‑steel hinges and screws. We then refit the timber sash and trim where needed, ensuring the window opens and closes smoothly again.

New Sash

When a timber window sash begins to rot, the wood becomes soft, spongy, and discoloured usually starting at the bottom rail or corners where moisture collects. As the damage progresses, the sash can swell, stick, or twist out of shape, making the window difficult to close and allowing unwanted drafts or water to enter the home.

In most cases, an efficient solution is to have a new sash made to match the original material and style.
