Extensions- 18 Sep 2019
To start off with the job went reasonably well - we were happy with the workers and the progress. but when we neared completion the work slowed up we waited 3 months for a response from Jordan. we had an issue where his plasterer hid the plumbing access in the wall. - This cost us £500 to sort and re-decorate so we came to an agreement that this was fine and at the time i presumed that Jordan was going to sort out the building control. so we then chased and chased but obviously since he had his money he wasn't interested he answered the phone and hung up. so we called building control and there are 2 small bits to fix which are all due to his work not being up to scratch. obviously i will be paying out for this - so please be careful when using him and dont pay him until you have all of the documents as he will not resolve any issues after being paid. i have had 2 previous building projects and this was by far the worst experience going. avoid dont use him thanks

Extensions- 12 Jan 2019
Wow, wow wow. I do not even know where to begin with this absolute gem we managed to find local to my father in laws project in Southminster, Essex. My in-law is not the easiest guy to work with but John worked so hard to fix all the previous issues a cowboy builder had left him with and he also worked very hard day and night (sometimes 15 hours!!!!) He went above and beyond service. We have never seen such perfect plastering (like glass) and structurally sound work being done by a true professional. He also finished the extension with cladding on the outside and flooring in a huge 80sqm space and to say we are all extremely happy would be an understatement. If you're wondering whether to hire John, please do not! He is worth every penny, he is reasonable and wants to do the job to please you and likes to finish to a very high spec and is always on time and reliable and gives you great ideas to make the house look perfect. Without a doubt the BEST builder we have ever hired and we cannot wait to use John again and again in the future. Thoroughly recommend and wouldn't hesitate to reference any of Johns future work. Thank you so much John, thank you!!
