Bathroom Fitting- 13 Mar 2019
We are so pleased with our new bathroom. Ricky and Jim were excellent contractors. Nothing was too much trouble for them. They encountered lots of unexpected issues but they took it all in their stride and carried out the work to an extremely high standard. I would recommend Ricky, R&M Property Service for any project. They are professional, courteous and have an excellent eye for detail and pride in their work. The next time we have some work to be undertaken they will be my first call. Thank you!!!!

Extensions- 29 Oct 2015
Steve and his team were a pleasure to work with as a first time extension builder they made the process stress free and enjoyable and the quality of work is great. They were very respectful of my home and my neighbours I would come home from work each night and other than the expected dust this type of work brings my house was left very clean. I would definitely recommend them and would use them again if I perform other works on my house.

Daniel completed a full renovation of our house and also managed the job from start to finish. The job included taking the house back to brick, new kitchen & bathroom fitted, structural alterations, updated plumbing & electrics and completely redecorated. Every problem we hit Daniel had a solution for, all work was completed on time and the communication during the job was faultless. Daniel kept us fully in the loop with the progress of the job. Daniel took a lot of the stress off us with his professional manner. I would highly recommend Daniel for any type of building work required.

Latest review:
This was a whole house refurbishment involving a garage conversion to an office and a utility room and a doorway through to the main room. The whole of the downstairs was opened up removing walls and replacing with steel girders. This required further footings to be installed and vertical and cross beams to support the structure. Also removed a door and windows to install bi-folding doors. All then plastered and made good. Cavell employs a team of very friendly, happy and accommodating tradesmen and his overall aim is to make sure the customer is happy with the end result. He was also very accommodating and helpful when problems arose. I have since employed Cavell to do a whole refurbishment of a rental flat and several other minor works and repairs. We are now embarking on another whole house refurbishment which will involve a two storey extension and walls to be removed and steels installed. I would have no hesitation in recommending Orange Tree Construction.

Extensions- 23 Apr 2023
Vince has been an absolute star. We have had an old conservatory knocked down, that was replaced with a new bathroom extension, plus the partial removal and rebuild of a lean-to. Vince has got a good attention to detail, kept us informed at all times, was very professional and polite and carried out a superb work. He also provided us with further advice relating to future works. We would not hesitate a minute to give another contract to Vince again.
