D.Baker Building and Maintenance Services LTD
No reviews yet
Extension Builder in Crawley, South East England
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

Latest review:
I was very pleased with this company so much so that they are starting a new job for me November 15. The building firms carried out a full loft conversion for me installing bathroom, brickwork, joinery, plastering, Roofing and installation of windows and double glazed doors. I have high standards and want everything to be completed in the same way, the workmen respected my home and always left if clean. My main contact was with the owner of the company Dwight Lynch, he was very flexible and Nothing was too much for him to do. He has an attitude which I like in a builder "customer not always right but must be happy" he provided me with ideas along the way and where things did not go to plan due to my own instructions he worked around the issue and provided suitable alternative options. I was very happy with the pricing of the job and feel that certainly I would recommend him and also I would use him again. He and his workmen were all trust worthy and I gave them keys to my house to carry-out work whilst I went on holiday. I had no concerns when I came back everything was as I left it.
