Dan completely renovated and refitted our kitchen in 2018 and also refitted our main bathroom and one of our ensuite bathrooms in 2021. Dan is a problem solver and pays great attention to detail.

Extensions- 13 Jun 2025
Liam and team did a great job building and completing our side return extension. The extension was built to a high standard and it all looks very neat and well done. Liam was good at communicating with us every step of the way and would even pop in if he was passing by to make sure that we were happy with the progress (and for a cup of coffee). He did everything he could to make sure that we came in on budget and was keen to help us with sourcing any extra's that we wanted. Overall, Liam, Clive and the rest of the team were knowledgeable, professional and skilled at what they do. I would recommend giving him a call if an extension is what you are planning for your home.

Extensions- 27 Jul 2018
Steve and Andy are absolutely brilliant. Steve initially came to quote for our job and we instantly knew he was the one we wanted to build our extension. We were very impressed with his experience and knowledge and his quote was competitive. Both Steve and Andy arrived every day they said they would and with their bubbly personalities, made a usually stressful experience, feel like a walk in the park. With 3 children, 1 dog and 2 newly released kittens, they accomodated us all. They communicated with us throughout and kept us informed daily. They handled the building inspections efficiently and professionally. Our single storey extension they built, has been completed to a high standard, incorporating roof lanterns, a window and bifold doors. It has made our family life easier, with the addition of space for a new kitchen and downstairs cloakroom, with the old kitchen becoming a bedroom for our eldest. Thanks so much Steve and Andy, you almost became a part of our family and we miss you already. We have no hesitation in recommending G L Building Services and suggest prospective customers don't delay in making that call!

Extensions- 25 Apr 2022
We hired Brothers Construction to knock through our existing dining room and garage to create a larger space. From the start Dan and Jay have been excellent. As others have said they are a completely professional company who arrive on time, do a full days work and leave everywhere tidy. Communication, sometimes on a daily basis, is excellent. Halfway through the project we wanted to make a relatively big change to the job which didn’t phase them at all and this, together with any additional costs, were always "run by us” before proceeding. To say we are delighted with the finished job is an understatement and we can’t recommend them highly enough. Thank you Brothers Construction for looking at our scrappy plans and turning them into reality. Desperate now to start decorating!

Dan is a very professional builder. He looked at every single detail of my garage and worked very to make sure he completed the job on time. He always came out with ideas to make my garage nice and safe. He insulated the floor ceiling and walls properly, plastered everything, fitted new windows and doors, built a very nice deck area, extended electric circuit, added spots light, renewed felt roof, changed the existing gutter, plastered everything. My garage now is ready to be used as an office with everything I need. I would definitely recommend him. Thank you Dan

Repointing- 6 Sep 2017
Very happy with Josh's work. He removed several bricks, went to a reclamation yard to get good matches, set them in and repointed other bits in the same area. He was thorough, the work is of a high standard, and he cleaned up well. He also rigged up the old gate so the garden was secure until the new gate arrived. (By the way he didn't spend any time working one-handed while talking on a mobile for which I was grateful.) His charges are very fair. I have asked him to quote for a bigger job. Was slightly wary of employing someone who had just joined MyBuilder but glad I did.

Extensions- 7 Apr 2023
Adam came around to give a quote seemed very professional and attentive. We paid a deposit to hold a date but was pushed back as was waiting for monies from a solicitor. They started the project in July 22 stating it would take 3 Months give or take for a wrap around extension, dormas, and a drive way however come December 22 still no where completed only wrap around extension started not evens dormas or driveway done. When asking what is going on just kept coming up with excuses and They kept asking for more money in the end got another builder to finish the project off none of their work was done properly as had other tradesman in to quote to finish it off and not one of them had a good word to say. All shoddy and they have got such a bad reputation around the local area with other tradesman. Just people beware of this company as they are rip off merchants and all they are interested in is getting your money then coming up with excuses why they want more. Their slogan is “not much we can’t do” well let me tell you something is should be “there is not a lot we can do” they have caused us nothing but heartache. I wholeheartedly regret using them. Just people beware
