Some of our Reviews.


“Ray and his sons have done a wonderful job on our patio, fence and gate. Turned up on time everyday. Price didn't change from the estimate will be definitely using Ray and his sons in the future! Highly recommended company! Very clean and tidy. Thanks again!” 


Customer in Sidcup

“Really nice family builders whose work cannot be faulted. They arrived before eight o'clock every morning which suited us fine as it fitted in with our work pattern. We were kept up to date as things progressed and any little issues that appeared unexpected were discussed and agreed by both parties as to the best way forward. The build was estimated to take from six to eight weeks but it was completed before time. I would have no hesitation in recommending Lawson and Sons to anyone, as they were completely trustworthy, honest and reliable.”
