  • I left school in 2006 to begin my career in construction, working with my Dad and Uncle who was the managing director of TPCT (The personal construction team). Here I learnt many of the skills I work with today, kitchen & bathroom installation, plastering, plumbing, painting & decorating, tiling and carpentry. Having earned my stripes over a 6-year period I decided it was time to set up my own business which eventually evolved to become the company I have today, D Baker building and maintenance services. I really do love what I do and I get so much satisfaction from delivering a high quality professional service to my customers, whilst giving real value for money. I have very high personal standards with my work and take real pride in what I do. This I believe is reflected in the outcomes I achieve, the positive feedback I receive and also from the recommendations that come directly from my customers. ​ If you have any queries about what I do or want more information then please do give me a call to discuss
