Emma Carter31/05/2024A superb experience from start to finish. Our extension was built exactly to our requirements. We had lots of questions and these were all answered quickly and professionally. Despite the weather not always being on our side, the build was completed within the week’s quoted time frame and completed to the highest of standards. All of the staff were professional and efficient throughout. Lots of people have commented on how good the extension looks! We would whole-heartedly recommend this company.
freemom22/05/2024Dan and his building team were fantastic. Could't believe they built my 5x3m garden house just in a few days. They had long drive to my place but still popped up in the early morning. They were professional and with good workmanship. The communication within the company was so good that they didn't make any mistake throughout the whole process. They could build exactly what I wanted. We were so happy for making the right choice. Can't recommend the team enough!
J MM01/05/2024Our build has been a massive investment for me to contemplate and I wanted to be 100% sure that they would provide the best for us - & they did ... I'm surprised they didn't turn down the job as I had a 1000 questions, before even starting ... But I honestly can not recommend the whole team enough! They have all been fantastic, they are friendly & approachable, give honest opinions but ultimately make sure that you are happy with the build, from start to finish, they have gone above and beyond. It is clear that they all take pride in what they do. I would not hesitate to recommend them. Thank you Dan and your team.
Robert Chesner15/04/2024Brilliant quality garden room. Looks great! Dan and his team went above and beyond during the project. Thank you
Stacey Morris05/04/2024After another company coming and building me a summer house and trying to rip me off. green leaf garden buildings 2 days later came and built one for me and WOW I love it! the guys have done a brilliant job! very quick service, reliable l, fits to preference would recommend to anyone.
BA18/11/2023I cannot recommend Green Leaf Garden Buildings highly enough!!! From Shane visiting us to discuss ideas to Ashley in the office promptly answering all of our (many many many) questions to Dan, Shaun and all the guys installing the Garden Building - every aspect was exceptional and highly professional. I am blown away by how I was treated as a customer. Everything was clearly explained to us including the internal dimensions (important as we are a tall family!!), the electrics and the finish to ensure that we were completely happy. The standard of workmanship is flawless and excellent and they were meticulous, tidy, and so very friendly. They left my garden immaculate with no signs of works!! I had a large Garden Building (12m x 2.5m) and they built it in a week!! On the first day of the build it snowed so I was expecting a call from them to cancel but they turned up on time and worked through the bad weather every day. The work ethic of everyone who worked on our building is highly commendable. I had to delay the build by a few days but they pulled out all the stops to complete it within the original timescale and without cutting corners!! Throughout the process, I felt that making the customer happy meant more to these guys than anything else. They went over and beyond and because of the standard of workmanship, I feel that the investment in a Garden Building is worth every penny. We obtained many quotes and were nervous when deciding who to go with but we definitely 100% made the right decision going with Green Leaf. Thank you to the whole team!!!! If you are looking for Garden Room - DEFINITELY go with Green Leaf! You won't be disappointed!
Paul Higgins07/11/2023This was a very big investment for me. It’s fair to say I was hesitant and nervous but the team engaged positively, answering all of my numerous queries and being very transparent in terms of specification. The build went very smoothly and there was clear flexibility when it came to queries while it progressed and these were answered and addressed promptly. Any snags were resolved quickly. Whilst not a major issue in the slightest I did note that the specification was for an armoured network cable to be installed but upon inspection, a standard cat5 cable had been used, routed in the main through some plastic trunking. However, I had a constructive and open discussion about this with the team. I decided not to have the cable replaced. Whilst the provisioned cable was at a different price point, through our conversation I elected not to progress on an invoice revision as my overall experience had been a positive one. However, that the cable provided was not as expected is the only reason I rate at 4 stars rather than 5.
Daniel Donaghy04/09/2023We are really impressed with Dan and the team at Green Leaf Gardens buildings. From our initial engagement back in December to picking the project back up in July Dan and his team inc Katie were informative, precise, hard-working, diligent and helpful. We're really pleased with the end product which the team went above and beyond to deliver on time. It has offered us exactly what we wanted from a garden office and will be able to be used all year round. The price we thought to be very reasonable and I have friends in different areas of the UK who seem to have paid an awful lot more for less. For garden builds we'd always turn to GLGB and are keen to use them again. We have already recommended them to others. Thank you GLGB :)
Simon O'Reilly12/07/2023Can't recommend the team at Green Leaf enough! From our initial discussions with Katie to getting the plan written up and then getting the work done in 2 days! Dan was very precise and kept to the schedule, although they quoted us until the end of the week but they completed the foundations and build within 2 days!!! The finish is far better than what we expected and we look forward to doing the next part! Thank you Dan, Katie and the whole team!!!
SS A02/06/2023Went over and beyond in building a new Sauna, Shed and Gazebo. We have recently had our second build by Green Leaf having had a garden room and shed installed by them earlier this year. We were so impressed by them that we decided to use them to build a second Shed, Bespoke Sauna and Gazebo. Once again Green Leaf exceeded our expectations and did a fantastic build and at a great price. We have always wanted a sauna but were never impressed by the ready-to-install versions so we asked Green Leaf if they could do it and they did it beautifully. The large gazebo now gives us a fabulous seating/hot tub area where we can enjoy our garden come rain or shine. Dan being the perfectionist he is thought of everything and the attention to detail is fantastic. In fact all the guys who worked on this building went over and beyond and were super friendly and hard working. Thank you to all the Green Leaf team for taking pride in their work (a rarity nowadays) and for putting the customer first. We could not have asked for more and are truly grateful.
