Paul was excellent throughout: communicated effectively and kept us well informed. Fair price that they stuck to. Prompt, punctual service. Supremely polite and considerate, always tidied up afterwards. Paul shows meticulous attention to detail and returned to tweak a couple of points he wasn't happy with. Friendly, would highly recommend.

From start to finish Paul was efficient, timely and polite. He also provided the lowest quote. The work was completed in less than a day, to a high standard and the house was left spotless. Paul's colleague was also happy to help me with some issues with my existing windows. Highly recommended.

This was always going to be a challenging job , very large patio doors on a first floor balcony with the only access for materials being over the balcony railings above a sloping drive . The job was completed on time for a competitive price by a friendly professional team who were very clean and tidy . No hard sell approach just a desire to provide what we asked for and a couple of handy tips in the decision making process . Thank you ZEN we will be recommending you to others .

Acoustic and standard double glazing fitted to front & rear of 1950's property. Paul was extremely helpful from the outset. The installation team were also very good and we have been very impressed with the service from Zen Windows. Would recommend without hesitation.

ZEN Windows installers Paul and Geoff did a great job replacing 2 porches, four doors and a host of repair jobs on our windows. The standard of work was very high and their customer relations were very good - nothing was too much trouble. I would definitely recommend this company.

Double glazing to rear or Victorian terraced house. Paul and the team were efficient right from my initial enquiry stage. I am so pleased with the finished project, and had so much choice and say in the product every step of the way.

Replacement patio French doors (doors damaged due to high wind hinge broken off). Paul kept me informed of progress throughout the whole job ,as where the work was carried out was at my daughters house and due to her and her husband being deaf they have difficulty communicating and so i dealt with all the communication he was very professional and his workmanship is of a very high standard I would thoroughly recommend them. A very professional company to deal with excellent skills at dealing with deaf people.

Patio style sliding doors on to balcony fitted. The rep went to a great deal of effort to find a way of installing the doors I wanted to a particular specification. A number of other companies had told me this was not possible. I found Zen windows extremely helpful in all stages of the work and I'm vey pleased with the result especially as other companies had been unable to help me
