Professional excellent company.
Customer Service
Found this company after lots of research for a replacement front door for our cottage, from our first visit to the showroom to completion of the fitting have nothing but praise for this company. Really good and knowledgeable advice, very prompt visit to measure and a surprisingly good quote , had expected higher. Really good at communicating re dates and fitting. The door was fitted by such friendly, polite,careful and skilful workers . A fabulous new door and we are 100% satisfied ! Can highly recommend this company.

Beautiful windows
Customer Service
We are absolutely delighted with the quality of our new windows and the professional way they have been installed. The four men involved worked extremely efficiently and methodically. All furniture was covered and taped and at the end of each day everything was cleared away and vacuumed. We could not fault them in anyway. We are very happy to recommend Derwent Sash Windows. From our first request for information the whole process has been seamless. We have never felt pressured just reassured that we have purchased an excellent product which has fulfilled everything we hoped.
