Before New Window Installation

To make sure everything goes smoothly on installation day, there are a few simple steps you can take:

  1. Strip your windows
    Take down curtains, blinds, or shades before the installers arrive so they have clear access. If you’ve got plants, picture frames, or decorations on the sills, move those aside as well.
  2. Clear a path
    Your installers will need space to move tools and materials in and out. Inside, shift furniture, rugs, lamps, and anything fragile. Outside, move items like flowerpots, grills, or patio furniture. Basically, anything that could slow things down or risk damage should be out of the way.
  3. Protect your space
    Installation can involve cutting, sealing, and sometimes painting. Drop cloths are usually used to protect floors and furniture indoors, and they’ll also help shield flower beds and landscaping outside.

The Guide to Window Installation

The purpose of this guide is to give you a clearer, step-by-step picture of what’s involved in window and door installation. While technical documents like E2/AS1 Amendment 10 often use cross-sectional drawings to show the end result, we know most homeowners benefit more from a simple breakdown of the process.

We’re here to help!

When you reach out to your supplier or installer, ask if a professional can come and take precise measurements. This is crucial. Even though many windows come in standard sizes, no two homes are exactly the same. Getting accurate measurements ensures the windows fit perfectly — avoiding issues like drafts, damp, or water ingress further down the line.
