Extension Builder in Hayes
I have been in the construction industry for 14+ years. During my time I've become a qualified bricklayer and learnt the ins and out of building from the ground up. I started sole trading over 4 years ago focusing on all varieties of construction ranging from foundations to the decorative final touches of the build. All aspects of the required job will be carried out by myself or by one of my highly skilled contacts who I have used for many years.
