10 Ground floor extension re-roofing
Posted 31 May
Within a couple of days of posting the job I got a reasonable quote and had dates arranged to book in the work. Liam is very friendly and easy to communicate with. Liam and his team arrived on time, set to work straight away and got the job completed really quickly. It was also during the hottest day of the year when the temperatures were sky high, but they still worked through it. The new roof looks great and everything was tidied away before they left. I would definitely use them again.Verified reviewerJob location: BB5- CChelsea P

Liam did such an amazing job for me and my sister! At first we only booked him to block up my old external door and pebble dash to match the outside. Then one job turned into 4 as he was so detailed and fast my sister asked him to plaster her living room and I ended up needing an internal door blocking up and my porch roof fixing! Every job he smashed and the comedy duo of him and Billy was elite! He also helped me fixed my shed door There’s no job he would say no too 10/10 definitely recommend My dad and his neighbours already have booked him for jobs now too! Will only ring Liam for futurVerified reviewerJob location: BB10 9.67 Making good when building plans can't happen

Liam was initially tasked with building an extension however, once the stone flags had been removed and the ground underneath revealed, no firm foundation was discovered. Sadly I had to decide to abandon the plans, but the remedial work carried out by Liam including rendering a back wall, was to a high standard and for a fair price, and I have my patio back again. He was as disappointed as I was but, that is what happens sometimes with an old house.Verified reviewerJob location: OL13- AAdam R

Keystone recently completed a number of jobs at my house. They were punctual and reliable throughout. Liam gave excellent advice and explained clearly what was required. The work was completed on time, to a high standard, and at a fair price. Would recommend.Verified reviewerJob location: BB510 Plasterboarding services excellently performed
