Superb service from start to finish. Express Building Solutions responded to our initial enquiry promptly, Dan called to quote the following day and fitted our gate the day after that. Dan very polite, punctual and helpful - did really good job on our gate and also fitted a small piece of fencing for us (which we hadn't requested in our original enquiry) to match the gate. Excellent all round service, nothing too much trouble, would definitely use again and recommend to anyone.

John turned up promptly, took time and equipment to inspect indoors how damp was getting in from roof and explain possible causes, then quick to get ladder to the roof to investigate further. He explained everything, took photos up on the roof with his phone, and his advice and quote seemed reasonable and not pushy. Came back in a day, did all the work up on the roof which turned out to be a lot more than he thought (reconcrete parapet wall) but honoured price, came back again to replace tiles too. Top man.

Paul and Dave did a great job. My garden was in such a mess!! Weeding was done, ivy growing around walls cut back. Worst job of all was the roots of a conifer growing under slabs. They lifted up slabs digging up and cutting back heavy roots. Slabs, including 3 further slabs were relaid. Added to that lawns were neatly cut. They tidied up after work was completed. Excellent work done in a professional way. 11/10 I would definitely recommend them to anyone needing work done
