  • 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

What experience do you have with similar extensions in West Sussex?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the West Sussex extension builder’s ability to deliver a result that meets your expectations.
