Very few tradesmen can engage in a detailed, professional and friendly manner. They took out an old kitchen and replaced it with a new one - which the helped source at below market cost saving us in excess of £5000. Right from conception to finish, there was full transparency of the costs and crucially at the end, no cost overruns. Definitely five stars and will reengage again for other building/renovation works I have planned.

Landscaping- 3 Jun 2021
On our first meeting I felt comfortable and was glad of input from Robin. Agreed to a plan and only had to wait a few weeks before work could start. All preparations made to protect my drive before skip arrived. All work carried out in a very professional manner and team were very polite and friendly. Even though weather was against ground works they provided shelter so work could continue. I’ve been very pleased with their approach and can’t fault the outcome. Although met with a couple of delays on garden furniture, (nothing to do with Robin and his team, circumstances outside control)all other aspects of this job have met with my approval. Was apprehensive of having people in but can honestly say there have not been any issues and when the skip was removed within an hour, Robin was back on site to clear and wash down the drive. So looking as good as new. It’s been a pleasure having them on my property and will look at using their services again in the future should the need arise. Nothing too much bother. So my thanks to them all.

What experience do you have with similar extensions in Whyteleafe?
