Extensions- 29 Apr 2020
Josh and his co-worker did a great job of rebuilding a brick wall in my garden and laying a sandstone patio. They had to deal with obstacles due to the coronavirus making it far more difficult than usual to get suppliers but they did their very best to get it all organised and completed it to a great standard. I would definitely use their services again if needed and would highly recommend them to others.
