excellent from start to finish

From start to finish the service we received was first class. Just one little think that I think should be pointed out to customers at the start of their journey is that occasionally there will be moisture on the outside of the window in damp cool weather. Other than that the service was first class and the workers were very careful when working through out our home

On time, had cloths on floor and stairs, worked straight through, nice men.

Yes, I would buy from them again. The salesman who came to our apt. demonstrated the window, showed all the features and wasn’t pushy. The product sold itself and has turned out exactly what we needed and hoped for.

The door and fitting was carried out quickly with little fuss and no issues

The two guys were very professional and left no mess and the job was completed in good time and I was kept up to date on the progress as I was in work whilst it was going on.

quick, clean, efficient and sensitive.

The service was quick, very clearly explained and painless. the men who installed the windows were very sensitive to my husband being ill and worked quickly, cleanly and left the house in excellent condition afterwards. We are very happy with the result so many thanks. we will use you again and have already recommended you to friends and neighbours.
