  • May I say how impressed I was with your installation team. It wasn’t the easiest of jobs I suspect but they were very careful and considerate of our home. They made a tricky situation run smoothly and the end result is great. Thanks to all and I hope we get to work on another project soon.

  • Just wanted to say how delighted we are with our doors and window! They look absolutely amazing. Also wanted to let you know that your fitters were fantastic – hard working, polite, conscientious and a pleasure to have on site.

  • Would like to say how pleased we are with the doors and windows. You have been great from start to finish, from the design process right through to the installation. The fitters were very clean and tidy and they have fitted the products very neatly and accurately. As you may know I am fussy but like jobs done precisely and accurately and you have done this.

    Mr. Darren Bourdon
  • We are very pleased with your doors and it has been a pleasure to deal with you.
    We are almost at an end with the building works and have constructed a patio at the door exit to our new kitchen.
    It should be photographed as an example of your good work!!

    Mr Clapton
  • We were looking for a truly slimline frame on our sliding doors, and no one came close to the quality and price of Urban & Grey. From the initial enquiry, through to site survey, ordering, and installation they were a pleasure to deal with. Always willing to go the extra mile to ensure a neat installation and the end result has far exceeded our expectations. We’re so pleased and have no problems in recommending Urban & Grey to others

    Ian Gardner
  • Thank you so much Urban & Grey for such fantastic customer service from start to finish. We are absolutely delighted with our bifold doors. The colour looks great and the finish is perfect. Anybody that says ‘bifold doors’ to us now we say ‘Urban & Grey’. We wouldn’t recommend anyone else.
