Zen fitted our windows in February 2021, they were great. Polite, professional and had great communication from start to finish. The price was very competitive for good quality. They arrived when they said they would and completed on time, leaving the place tidy when finished. But the real plus was in the support after the installation. We only had a small issue with one of the windows not opening. But when the manufacturer was going to make us wait for 5 weeks for the repair, Paul came quickly and was able to identify and sort the issue within 1 hour. I highly recommend Zen windows, they are very easy to work with and, as I have found, very reliable and trustworthy.

Paul did a fantastic job replacing the broken window. He replied promptly to the quote request and came out to look over what needed to be done prior to doing the work. The new window looks great and Paul took away all the waste material and left the area of work very clean.

Replaced all windows and a french door. Zen fitted in the job early to enable me to have other booked work carried out. Paul (owner) kept in regular communication and was always extremely polite and helpful. The fitters arrived on time and were friendly, very helpful and courteous. Nothing was too much trouble and they helped replace curtains, blinds etc. I would highly recommend Zen. They’re lovely to deal with.

Paul kept in touch with me RE prices & the order. He turned up when he said he would. He replaced misted up windows/door & then completed 5 other little jobs that I either asked him about or he saw. e.g. sorted a sticky handle, sealed a leaking gutter. He was polite, friendly & respectful. I recommend him 100% Thank you Paul!

I had 5 double glazed windows installed. Paul visited my house and did a quick survey for the quote. During the visit he answered all my questions and advised where necessary, at no stage did he try to "sell" anything, he just measured, advised and left, it was all done in about 30 minutes. His quote was roughly in line with 2 previous quotes I had received so the only decision I needed to make was which one? Paul won the contract for the following reasons: 1. As described in the first paragraph 2. Paul came across as a very personable person, easy to talk to, very polite and not all "pushy". All the work was done very efficiently and completed in two days. While he was in my home he was polite, quiet and just got on with the job in a very professional manner. The work was done to a very high standard and the work area was always cleaned up after each stage. I am very pleased with my new windows and as a result I have invited him back price up replacement French doors and a back door. I can happily recommend Zen windows and I feel confident you will be pleased with any work they do.

Great customer service from enquiry to completion. Paul, our contact, has been extremely helpful and accommodating and our appointments have been easy to make and have been fitted in around our lifestyle. The installers, Tim & Mark, were friendly and professional. They cleaned up after their work well and were hard working & trustworthy. Would definitely recommend ZEN to anyone looking for new windows!

From the first contact until completion Paul could not have been more helpful. The work was completed on time (fitting it into my schedule of availability!) to an excellent standard and was very good value. At the end, apart from a lovely new back door, you would not have known he'd been there. I cannot speak highly enough!

Paul was excellent throughout: communicated effectively and kept us well informed. Fair price that they stuck to. Prompt, punctual service.

Friendly, would highly recommend.

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 .

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
