Our usual recommendation

Cedar

Generally speaking, cedar gives the best results for timber joinery. It has better stability, strength and lightness than the more common pinus radiata, and resists warping in New Zealand conditions, which is why we use it for our bi-folds.

How a window goes in

From drawing to done.

How a Westpine window is fitted into a weatherboard wall, one layer at a time. Keep scrolling.

  1. Step 1: The framed opening. The builder frames the opening a little larger than the window: trimming studs each side, a lintel above to carry the load, and a sill trimmer below.
  2. Step 2: Building wrap. The wall is wrapped, and the wrap is cut and folded into the opening so the framing is covered right to the edge.
  3. Step 3: Flashing tape. Flexible flashing tape seals the sill and the corners of the opening, the places where water tries hardest to get in.
  4. Step 4: Sill flashing. A metal sill flashing is let into the trimming studs each side. It runs under the sill and turns down over the weatherboard below.
  5. Step 5: The Westpine window. The window goes in on packers with a 10 mm gap all round, is levelled and plumbed, then fixed through the jambs into the trimming studs. The facings come fitted.
  6. Step 6: Head flashing. A metal head flashing sits over the head facing. Its upstand goes behind the building wrap, so any water running down the wall is shed out over the window.
  7. Step 7: Weatherboards & scribers. Bevel-back weatherboards go on from the bottom up, each lapping the one below, and finish tight to the facings. Scribers close the joint.
  8. Step 8: Air seal. From inside, a backing rod and sealant close the gap between the frame and the framing, so there are no draughts.
  9. Step 9: Lining & architraves. Plasterboard lining and architraves finish the inside. The window is ready to paint.

Villa renovation

Joinery that looks like it was always there.

Sashes rot, sills split, and an extension needs new windows and doors that sit comfortably beside the originals. We replicate existing heritage profiles for villa, bungalow and period homes.

After: the finished conservatory with timber doors and windows and a checkerboard floor
