From the day Nick came to quote for our single storey one bedroom Annex everything was on time on budget and the best quality. The team were friendly efficient and extremely tidy. We were thrilled with the results and one minor snag was dealt with immediately and without question We would absolutely recommend Oakview Construction Ltd Nick and his team. We wished we had used them for the kitchen fit as well as this was the only part of the whole project that didnt go like clockwork.

Landscaping- 3 Jul 2020
I can not thank Robert and his crew enough,I have been involved in property development for 38 years and have had countless trades people come and go. I am used to being underwhelmed and know all the usual add on's that regularly get trotted out during a project. So it was a refreshing experience to use Robert. This project was for my disabled brother to enable him to use his garden,Robert and his team were considerate and understanding working around someone in a wheelchair who always seemed to be getting in the way whilst they were trying to get literally tons of materials through the house. They worked liked machines, didn't stop when it rained and finished the job in 5 days whilst being a man down when I would of been amazed if they had done it in 7 days. The workmanship is faultless, they are courteous, on time and tidy. I can highly recommend Robert, I was keen to get a run down of his building trades skill set as he will be the first person I, or my family will call when we want anything done, and in a nutshell he can do pretty much anything you may want done to a property. A big thank you Robert and team from all of us.
