This company came to me to give me a quote when I needed a Porch to be knock down and rebuilt. When they arrived to give me a quote they was very professional and gave me good ideas on how they would do the work. A few days later I received a quote which was professionally done. It showed a step to step guide of the breakdown in cost, to do the work. Anything I was unsure about, it was very easy to speak to them on the phone and they answered my questions speedily. They gave me confidence on how I should and could have my work down. I thought the quote was reasonable, therefore I asked them to come and do the work. They arrived each day on time everytime. They were very reliable, polite and helpful. Everytime they finished work they would clean up and put things away ready again for the next day. My work on the Porch has finished and I am very happy and proud of the work. They take their time and pride to do the work as if they were doing their own home. I would rate them more than 100% and my family and friends are all very happy and pleased with the work. Its hard to find a very good trustworthy builder. I can honestly say they are me best. I may have other work for them in the future. My house look beautiful and very homely. I like to thank them for making my home a better home.
