Recommend to Anyone

They installed some aluminium bifold doors for me a few months ago and I'm extremely happy with how they operate and how they look. Would recomend Klosen to anyone after bifolds.

Excellent Quality & Quick Service

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.

Very helpful and competitive on price. I purchased several lift and slide doors off them recently and they were very quick delivering them.
