Catherine Havis - Image 1 "Brilliant work by Alex and Reiss. Ripped out old rotting retaining walls and archway, replaced with composite sleepers and redid the stairs and some patio bits and shingle. Looks fantastic, actually asked them to do some extra jobs while they were there as we were so impressed. I have already asked them to do a quote for my dads garden and also another quote for some further work for us. Punctual, hard working, very pleasant guys, excellent work, all washed off and tidied up."

"Workers arrived promptly and were friendly, professional and efficient. Contact with Alex was easy and he was very responsive via WhatsApp, sending photos during and after the job as requested. Alex provided helpful suggestions for maintenance and went above and beyond by removing a tree branch that could potentially have caused further issues!"
