Quote builder
Your house, in a band.
The number of windows, the style and the colour decide most of the price, so those are the questions, with any doors. The band is the one Kerry quotes in, fitted with VAT; the quote after the free survey is fixed.

Questions about the quote builder
Why a band and not a price?
Because windows are made to measure: a small landing window and a wide lounge window are both "a window". The band covers the usual spread of sizes in a Gwent house; the survey measures yours and fixes the price.
What is not in the builder?
Aluminium windows, bi-folds, patio doors and conservatory roofs, because almost every one is a one-off size. Kerry prices them at the survey, and the services pages give the starting prices.
Why does colour change the lead time?
Coloured profile is foiled before we cut it, which adds a week for anthracite and two for heritage green and oak. White is cut from stock.
Do I pay for the survey?
No. The survey and the written quote are free, and there is nobody ringing afterwards to chase you.
Start with a free survey.
Kerry measures every opening with a laser, checks the lintels and the cills, shows you the colours and the glass, and writes a fixed quote at your kitchen table. The quote builder gives you the band before she comes.
