One of the most professional companies I have ever dealt with. My house suffered with a land slip in the garden and Keestone were appointed to carry out the remedial works. From the beginning to the end of the project I was fully informed by the management team ( Steve & Mick) of what steps were happening and when they would be completed. The workmen were on a different level and properly grafted every day. Even the back office staff are super helpful and friendly. A very classy, reputable business. I would have no hesitation with recommending this company .

We had the pleasure of having Keestone do some restoration works at our home. They have a fantastic team and we were listened to with regards to all of our concerns. Mick and his team have a excellent work ethos and honest approach. We were initially very worried with the amount of work that was required, however, we were out at ease by Keestones professional approach to the job and they had instilled confidence in us that we could trust them to do a professional job. Thank you

I am happy to express my thanks to the whole Keestone team for the amazing job you have done for us recently at Hemsworth Christian Fellowship. From the initial visit to finishing touches I have been so impressed with the quality of work, the professional approach and the excellent communication from everyone involved. Everyone at the church has commented how great it all looks, and it has been well worth the disruption to see it as it is now. Following a stressful period which caused the damage it was a relief to be able to hand over the restoration work to such a friendly and competent team and
