Groundwork & Foundations- 20 Sep 2018
JPD boys came to rescue us when we were almost stuck with our RC foundation on our project, we got a very competitive quote from them and the job was done to a very high standard. Not only did they helped with that, they also gave us a quote for the block work, again this was done without snagging. We will definitely use them over again and recommend them to anyone anytime.
