May we thank you for a job very well done.
From the Sales Office at Northampton, to the excellent groundwork and building team and the most friendly fitters (what cold weather they had), we cannot speak highly enough of the service we received. There are very few firms around these days that you can say that about.
We are delighted with the finished product and look forward to many years of relaxing and "sunning" ourselves in our conservatory.
With grateful thanks,
