Excellent Quality & Quick Service

5 5 1
Klosen recently installed 3 sets of sliding doors on my extension and I found them to be superb from beginning to end. It was very helpful that they were knowledgeable of many of the systems available and were able to offer multiple products, as this helped me get a good quality product that was also competitive with other quotations I received. Would definitely use them again.

Happy & Would Recomend

Klosen installed some aluminium windows, sliding doors and a front door for ourselves recently. Very easy to deal with them all, and extremely happy with the products received and the installation quality. They offered a great range of products, not just one or two, which we found very important when making our decision on window & door supplier for this project. We would happily use again and recommend.
