No extra costs to original quote despite a few additions to original plan including repositioning of garden gate and reversing hinges. Very efficient, helpful and polite work force. Delighted with new patio. Thank you JLS."

    Lee - Image 1 "I went on trust a trader to find a good builder and I found JLS building Services. My home needed a lot of work doing inside and out. So I met up with Justin from JLS and straight away I knew I had found the right builders! He put my mind at ease as there was so much to be done and I was worried about the cost, how long it would all take and if they could do all the jobs needed. I was amazed at how quick, efficient clean and trustworthy the builders were. Fitting a new kitchen, bathroom, new floors, new boiler painting and decorating etc. work on the outside was brilliant too including Insulation and Silicone render. I will be using JLS for any future jobs I may need. I couldn’t recommend them enough and it was stress free too. Thank you JLS"

    TRACY - Image 1 "I would highly recommend using JLS Building Services. From the first meeting with Justin to explain what I would like done until now, where we just have a couple of things to finish off it has been a pleasure dealing with them. Justin has always been available if I had any questions and is always very prompt in replying. I advised Justin I wanted to knock down an old concrete garage and build a very big shed that had 2 separate storage spaces that had its own doors. One to use for garden tools and the other as general storage space, in its place. He gave me some advice on what could be built. I had another long list of other jobs which needed to be done too which Justin has also been able to arrange. The final results are amazing and exactly what I wanted. I am so happy with the results. Big shout out to all of the contracters Dean, Rob, Steve, Jay, John, Luke and Dan who have all done a fantastic job, highly professional and a pleasure to have around."
