Extensions- 5 Nov 2016
Leslie carried out the following works: chemical damp injection to walls on rear extension, reroute down-pipe, repair fracture on rear wall, install gutter hedgehog. Hopefully, this will resolve some of the issues we had with damp, a blocked down-pipe and an overflowing gutter. Leslie arrived on time on the first day but was delayed a few hours the next day. However, the work still was done within two days as expected. Thank you!

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.
