The argument

A window is not a pane of glass. It is a frame, a drainage path, a hardware set and a seal — installed as one system.

Get them right and the window disappears into the architecture. Get one wrong and it announces itself every rainy season.

The Window & Door Assessment

We do not quote by the square meter sight-unseen. We supply the system and we install it.

01

We look at the opening

Orientation, exposure, wind and rain load, structural condition, and what the opening is actually being asked to do.

02

We specify the system

Profile, glazing, hardware, drainage and sealing chosen against those conditions — not picked off a price list.

03

You get the reasoning

Written down, so you can compare it against any other quotation on the same terms.

04

We install it ourselves

The same people who specified the system fit it. Nothing is handed to a subcontractor at the point where most openings start to fail.
