Extensions- 7 Apr 2018
Overall they did a very good job and the end result was better than expected. They were a bit untidy, so something to keep an eye on. However they were very responsive to any queries I had.

Restoration & Refurbishment- 20 Sep 2016
Steve and his team were an absolute asset at the start of the project. His attention to detail and numerous suggestions were very much appreciated. All of the work carried out was exceptional. Steve is personable and it has been a difficult for me to leave negative feedback. The standard of work I received in the latter stage of the project was mediocre at best. I know Steve is passionate about wanting to rectify all issues but is incapable of delivering. Certain issues I was happy to overlook such as him deciding to change my chosen kitchen without discussion with me, ordering grey radiator instead of black, ordering victorian style taps for bathroom when I had provided details of the modern taps I wanted and being told I owed an additional 10k because my previous payments had not been accounted for. In November 2015 I was told all extensive works would be complete in April 2016. Endless failed deadlines and poor communication has meant the work has not been completed in October 2016. Faulty electrical wiring, damp, missing carpentry, spilt paint on furniture and new flooring, miss matched plug sockets (originally put in wrong position) are just a few of the outstanding issues. Approx 6 deadlines have been given to rectify but there is no attempt to complete. I have spent 55k with Steve and have been left to resolve these issues at my own expense.

Extensions- 25 Apr 2023
Overall, a shocking experience. Our project started off well, but it didn’t take long for issues to arise leading to 12 months of utter chaos. Stages were not completed by agreed dates, he started not turning up, quality of work started deteriorating, subcontractors ended up contacting us direct as they had not been paid/had payment concerns…. the list goes on!! Once we started to raise our concerns things got worse. Ross did not take any ownership for the issues and chose to continuously blame us instead and caused us considerable amounts of stress noting the size and value of the project. Ultimately, we were left in the position of having to complete our project ourselves and rectify multiple issues/non compliances highlighted by building control for which Ross was aware and chose to ignore. Note: We hired Ross under his previous company “Goulding Developments”.
