Groundwork & Foundations- 10 Oct 2025
Always a concern hiring someone you don’t know, but from the beginning Charlie has been excellent with communication and job started on time and finished on time. The guys were polite to our neighbour and very careful whilst using her access for our job. Very well priced and they were content to take the job on with difficult access where others clearly priced themselves out of the job or let us down. Would highly recommend.

Carpentry- 4 Aug 2018
Jason was very easy to communicate with before the job and turned up exactly when he said he would. The work was completed to a high standard, and on time, which was amazing given it can't be an easy job building a flat roof on the hottest days of the year. There were a couple of problems with the work, but they were resolved quickly and without complaint. I'd recommend Jason to others and would use him again on future projects.

Extensions- 19 Jan 2019
Graham is a knowledgeable, honest, conscientious and thoroughly nice bloke. I chose him because I could tell immediately I could trust him implicitly with my project and my home. I am delighted with my new extension, kitchen and my bathroom which harbours my Japanese soaking tub. Graham allowed me to follow my vision even though he may not have been entirely convinced about my metre wide bathroom! He offered advice throughout the process and explained things very clearly. His son Nathan is equally as brilliant and is learning from the best. The skilled people Graham uses for his jobs are all masters in their own profession and very friendly. After 4 months I miss seeing them all! My job was a big one including load bearing wall removal, chimney breast removal and a side return extension. I have 7 steels in place which are huge but Graham got on with the job in hand and produced what I have now, my beautiful new home. He fitted my navy kitchen which went perfectly (despite issues with wickes) and my bathroom with the tub. He built oak steps up to my bath which are a real feature in such a tiny space. He is a master carpenter afterall! I truly would not hesitate to use Graham again. In fact he will be building my book cases and my stable door this year. I am relieved to have had such a positive experience during what could have been a stressful time and I have Graham to thank for being so fantastic at his job, for managing the project and for putting up with me!

Bricklaying- 21 Jul 2026
I've run my own building firm in the Southwest for 25yrs. I came here to project manage a job for some very dear friends. Needed a local brickie and after chatting to him, knew Mark was the right man for the job. He and his team have been nothing short of brilliant. Punctual, great communication from the outset, polite, highly knowledgeable, great work ethic and extremely conscientious of the quality he stives to leave in a job. If he was operating in my part of the country, I'd have him on all my sites in a heartbeat. The clients who actually own the house we've just put a lovely double extension on, are over the moon with the result, largely due to Mark's efforts in getting it built. Easy 5* review to write.

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- 22 Jun 2018
We are 3 weeks in to a 5-6 week build. I really cannot speak highly enough of Owen, Will and Tom. Within 3 days they had created footings, knocked down walls, dismantled our kitchen and had steels in ready for the extension. The speed of progress has continued, the project management has been outstanding, everything delivered on the right day, without lots of materials being stored on site. They have been incredibly polite to our neighbours, ensuring they are parking with consideration and not inconveniencing anyone. I feel incredibly fortunate to have found this team via this site. We look forward to working with Wright and Wrythe on future projects, we wouldn’t go anywhere else.

What experience do you have with similar extensions in Harwich?
