Restoration & Refurbishment- 2 Oct 2024
I just wanna express honest with you I met up with Mr John on two occasions and I told him everything I want confirmed we confirmed the price he sent us a spreadsheet but later on confirmed a figure once that was done he said send pictures. I’ll get the items for you and will get everything done for you in a time which was originally 2weeks . Then 2 month and half later he ignore my calls very unprofessional and has outstanding task he left and still not even correct , I am not able to go in to all the details but I tell you for free how I’ve been treated for the last few weeks mentally draining and for example he said let’s get his electrician because he needs the person doing the work side-by-side and if I’m honest, they’ve done nonsense because the media where the plug is is not correctly positioned in fact, the TV does not go in properly as they positioned it in the wrong place they didn’t check where the TV was meant to go initially I have to sort this out myself.

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Chatham extension builder’s ability to deliver a result that meets your expectations.
