Landscaping- 23 Apr 2025
Organisation of the work, friendliness of workers and painting of fencing was to a good standard. However the work completed on the decking was so lacking of standard or pride in setting high finish work standards. Due to the lack of poor workmanship we are now having to consider getting someone else in to rectify the decking, if this is now not possible we are even contemplating on replacing our 4 year old decking.

Extensions- 29 Sep 2015
My wife and I embarked on a 38sqm extension in March 2015. It included 3 steel beams, with 1 across the entire back of the property. The existing kitchen and dining room was extended, including a new room and bathroom. We entered the project with a degree of uncertainty. I was keen to choose a professional, trustworthy builder thus avoiding arguments and miscommunications. We met John twice. We were impressed by his easy manner, past experience, professional knowledge, reasonable price and equally, his excellent reviews. The project started in March 2015. John was present throughout. He volunteered updates, left the site clean and made the process as comfortable as possible. No easy feat, as we were still residing at the address with children. The project finished within the time scale and on a happy note. Other than the obvious bias of my wife and I, who are extremely pleased with the finished project, we equally receive constant compliments from others more neutrally regarded. Those that visit are complementary about the scale of the extension and its impressive finish. The attention to detail and high quality finish that I hoped for, is present throughout. If your home is your greatest asset, leaving it in the hands of someone else demands a great deal of trust and a jump into the unknown. Based on my personal experience, I am pleased that our instinct was vindicated. Entrusting our project to John Bedford, proved to be the best decision of all.

MASSIVE thank you NBKS BUILDERS for the outstanding job completed for my Day Nursery. NBKS guttered our building and completed a full renovation and single storey extension in 3 & half months, and garden. Neil Director was a diamond from day 1 till end in his approach to our job, he always offered new ideas along the way, no request was to big or small, very adaptable. His Team was friendly, consistent, came every day including weekends to meet our September reopeing deadline. Neil is easy to speak with and project managers the full job. Neil has Exstended contractors who work alongside his team like electricians, plumbers, carpenters and together they worked on point to meet our deadlines. Even though NBKS have completed, they stay in touch to ensure alls working well, which this feels very supportive. NBKS came to our Nursery relaunch and open day, the High Sheriff Of Nottm was impressed with the build and the time frame completed in. We definitely recommend NBKS to all projects

Carpentry- 28 Apr 2023
I found Andy and Matt Cooke of Cooke & Co Joinery on My Builder after a long search to find someone to strip 3 pine doors which had several layers of old paint.They have been absolutely brilliant from start to finish. They came and took the doors away having told me that the stripping process takes about 4 weeks. They have have just refitted the doors which look lovely. They are clearly very skilled in their trade. Andy and Matt were a pleasure to have in the house. They were extremely tidy, very friendly and carried out out the job exactly as I wanted. I am delighted with their work and would recommend them to anyone.

Josh and his co-worker did a great job of rebuilding a brick wall in my garden and laying a sandstone patio. They had to deal with obstacles due to the coronavirus making it far more difficult than usual to get suppliers but they did their very best to get it all organised and completed it to a great standard. I would definitely use their services again if needed and would highly recommend them to others.
