My names Tom, I have been in the real estate sector for over 10 years and have done everything from general property maintenance, new bathrooms, painting/decorating, demolition contracts and most recently constructed 9 ultra high spec homes. High quality and impeccable workmanship are key values to me and ensuring the client is satisfied and more, with the work they are receiving. I am very well connected with all trades and can provide a top tier service for all types of project management no matter how big or small the job may be. I am also extremely capable at doing many manual labour jobs, but often favour a shorter timeline for my clients project completion and therefore prefer to draft in experienced trades to get the job completed. Above all I am very friendly, well spoken and always keen to deliver what is asked of me.

I can't recommend Tom highly enough. He's a lovely friendly chap and supremely good at what he does. He put up 4 pairs of new curtains and the poles as well as taking down the old ones. Everything is looking fab and perfectly positioned and the curtain poles will not be coming down in a hurry! Everywhere left spotless too. I'll definitely be in touch the next time I need work doing. Thanks Tom :-)

Ben is a highly competent and reliable builder. He completed our kitchen/garage conversion and bathroom work efficiently and to a great standard. Ours was a complex job with many different components all of which Ben tackled with no complaints, routinely offering practical solutions to any issues that arose which enabled us to retain our look and feel while keeping to budget.
