Daniel provided a competitive quote. I wanted Howdens kitchen and he allowed me to directly deal with Howdens. So in effect I paid the Howdens trader price. The best part was for him to suggest some additional work which made a lot difference. I really appreciate him for that. He charged extra but it was worth it. Daniel and Team worked very professionally and finished the work as agreed. The most important is that Daniel is a good man. I will definitely call him for future work. Highly recommed

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.
