About DIY

Everything in this collection is the same product our professional crews fit, packaged so a homeowner can do the job on a Saturday. No trade account, no special tools beyond a drill and a pair of shears, and instructions that assume you have never done it before.

Start with the job, not the product. Draughty double hung windows: the complete kit boxes every part for one window, and the step by step guide shows the whole job on video first. Doors: the standard and premium door kits. Rot in a sill: the epoxy starter pack puts the stabiliser and filler in one box. Cold single glazing: secondary glazing film is the cheapest winter upgrade there is.

Two rules from our installers: measure before ordering, and watch the video before starting. If your job involves rebalancing a window, the sash weight calculator does the trade arithmetic for you, and every kit page lists exactly what is in the box.
