Extensions- 5 Jan 2022
We have chosen Mike to fix the botched work of another builder, although we agreed an initial price, he came back on it twice and added additional cost, which we accepted (since we were in a desperate situation). On top of this he was trying to charge me another £400 for waiting for a couple of hours for a pot of paint which we pushed back and disagreed. The whole attitude towards money is a disgrace, on the day that I have given the team £60 worth of drinks for Christmas, they took home unused materials (which I bought worth £50) and when I questioned it they said they used it after the work was completed???! I would have let it go if the craft ship was good, but it isn’t, we have noticed unfinished work at some places (silicone half done, grout not done in some places, staircase with gaps) and after a few messages, he isn’t responding. My advice (if you are still going with him) have it all in writing, ask for a breakdown(he wouldn’t give us one) keep an eye on any materials you provide them and finally don’t pay them until you double check every single corner. I wouldn’t recommend them to my friends and family

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.
