Old artex ceilings in bedrooms, hallway stairs and landing skimmed to flat with a high standard, finished off and decorated white to a high standard. A bedroom was given a full redecoration too, going from a faded, outdated look, to a crisp modern one. I am very happy with the work and everything is to a high standard.

It has been a pleasure to deal with such a competent and reliable team. Good communication, welcome help with the bureaucracy/ permissions and minimal disruption at the house.

Fyfield Multi-Trade

Extension Builder in Alton
I’ve been around the building trade for most of my life. My dad was a builder, and when I was four he built the family home we lived in during the 1980s. I spent a lot of time on site watching the trades, learning the craft, and developing a passion for quality workmanship. After leaving school I worked for my dad’s company for three years before taking a break from the industry. I returned at 27, helping with projects my dad had won, quickly taking the lead on jobs and eventually setting up my own company in 2001. I ran multiple projects at once, earning a reputation for reliable, high-quality work. In the last four years, I’ve been working for a local small building company, gaining further experience on a variety of projects. After recharging during the pandemic, I’m now ready to help clients again with both small and larger jobs, always delivering quality work, clear communication, and a job done properly.

Kitchen Fitting- 7 Jul 2016
Excellent! We hope to use again! I cannot recommend Alex & Richard highly enough. We had a full kitchen/diner knock through and complete refit. They were an absolute pleasure to have working at our house. From the moment they came round to quote for the work, they were pleasant, prompt, clear and concise. They were able to start work quickly which was great for us. The professionalism and attention to detail was amazing. Always arriving on time, they often stayed late to complete their work which lasted just over 2 weeks. They are a credit to the building industry and themselves. Our finished kitchen/diner looks amazing. We are so pleased. Please do not hesitate to hire these guys - you won't be disappointed!
