  • I had a loft conversion done a few years ago and because of my stupidity I let a 'so called' unique designer loft company get away with my money and no building control. I contacted Coey & Johnston and asked for a quote to finish off the works to obtain building control and also look at a damp problem I appeared to be having at one end of the house. He arrived when he promised he would and not only quoted but also gave me great advice on how to proceed. Happy with the quote i asked him to go ahead. Over the period the guys were on site they started and finished bang on time. They left the house cleaner than when they started every day and were completely self sufficient. They never even wanted a kettle boiled. I can't thank them enough for their professionalism. They were polite courteous as well as great craftsmen.

  • As a local architecture practice we have worked with Coey & Johnston on many projects, from simple domestic extensions to complex commercial projects, and have always found their management team and tradesmen exceptionally knowledgeable and obliging. We recommend Coey & Johnston very highly and look forward to many more future projects with them.

  • We engaged Coey & Johnston to complete the addition of a sunroom and renovate the kitchen area of our home. They were involved with the project from start to finish, initially engaging with the architect to ensure we maximised the available space whilst operating within our budget. Once the design had been finalised Coey & Johnston gave us a clear and precise time-table for the completion of each stage of the project, kept us informed of the progress throughout, and dealt directly with all relevant building authorities on our behalf to ensure the building was fully compliant. The time-table was adhered to throughout, and the project was completed on time and within budget. The site was maintained to the highest standard throughout the project with a minimum of disruption for ourselves and our neighbours. The finished product is a superb sunroom and kitchen facility, finished to the highest specification. This is now the most popular room in the house. I wouldn’t hesitate to recommend Coey & Johnston for any building project large or small.
