Our Promise

Our promise is simple, we treat every home as though it was our own.

Thornton's is one of the few companies in the North of England that has actually outlasted its guarantees and is still building upon its successes to continue giving clients value for money and a superior service second to none.

We are first for quality with the backing of such companies as Rehau, Ultraframe, Pilkingtons and Rock Door to name but a few. There is no doubt that we supply and install the best.

For our company the installation of the windows, doors and conservatories is of paramount importance it doesn't matter how good the quality of the window frame, if the fitters are not up to the job the end product can be spoilt. All our manufacturers and fitters are time-honoured tradesmen and they are all employed by ourselves full time we do not have any sub contract or peace work fitters. The job takes as long as it takes and this way one can ensure perfection every time. All of this is backed with an Independent guarantee from the IPWFA (Independent Plastic window Federation) which is a requirement as a FENSA registered installer.
