From our beginnings in 1994 to the current we have always strived to be worthy of a first class reputation.

We are truly a family run company, and our family values are just as strong in our company. We know how much trust every customer puts in us when they come to us for windows, doors or conservatories and that’s why we never take that trust for granted.

We install products to the highest of standards and specifications, and deliver the quality and service that we would expect in our own family home.

"We have used Unicorn Windows for over 20 years on all of our houses. Service always fantastic and nothing is too much trouble for them. We had a lock malfunction on a kitchen external door they fitted after 10 years of heavy use and after calling them the lock was replaced the following day. Would always use them great family business."

What our customers say

5/5

Delighted with our new front door, with the order carefully taken, delivery on time and installation faultlessly done. Really appreciated the assurance of receiving insurance cover both for the deposit payment and for the door itself. Will definitely use Unicorn Windows again, if needed.

Lance Redler

5/5

High quality product built by very professional experts. Did an excellent job for us building a conservatory and worked around any structural problems as they arose with no fuss. Highly recommend.

Carole Bryer

5/5

We have used Unicorn Windows a few times over the past few years. Everybody who we have dealt with, from the people that give the initial quote, the team on the office and the glaziers are all friendly, polite and helpful. I would definitely recommend this company.

Yenac Kram

5/5

We called on Unicorn Windows Ltd to look at our Bi-fold doors that had dropped with a gap that has been letting in a draft because of another company’s wrong fitting. The work was done quickly and professionally with no problems whatsoever. Highly recommend and trustworthy company.

Mark Packman

5/5

David and his team couldn’t have done any more to improve on the experience, the work was well organised, tidy and courteous. They have replaced the windows, a new front door and new patio sliding doors, all such good quality. Highly recommended, lucky to have such a high quality local business

Will Pratt

5/5

Fantastic company. Had new windows fitted by them in August and they did a great job from start to finish, from the initial sales visit, to the surveyor, and then the fitters... Wouldn't hesitate to recommend them, and indeed have done to some of my friends who were also delighted with their service.

Steven Foster

5/5

A big thank you to the whole team at Unicorn Windows who have recently replaced our cladding and fitted a new front door. The house looks so much better and more modern. The fitters were neat and tidy, polite and cheerful, despite having to work in extreme heat. We would highly recommend Unicorn Windows!

Beverly Robertson

5/5

We needed all our windows and most of our doors replacing. After receiving 4 quotes, we decided on Unicorn and we are so glad that we did as we are absolutely delighted with the finish. It was not the cheapest quote but it was an extremely thorough job. The father and son fitting team were really nice guys too! Five stars all round!
