“I can't fault Irinel and his team. Hard working chaps, tidy, respectful and did a fantastic job. Hired them to knock down a supporting wall, fit steels, build a utility room, re-plaster the entire kitchen/diner, fit floors, new electrics and insulation. A team of 4 came in and just cracked on with it. I like the fact they offer advice and suggestions and were patient with my wife changing her mind every minute. Highly recommend them. They don't take the mickey and charge a fair price for a good job. They really stand out as a team that does an entire project and doesn't try and charge extra for every little change you make — and genuinely want to do a great job and leave the customer happy.”

Working within lockdown restrictions and ensuring we were happy along the way. When builders' merchants were closing and stores couldn't deliver goods on time, Irinel found alternatives ASAP to not slow down the project. Irinel was always happy to discuss changes and even shared his ideas on things which helped us tremendously. He helped get the electrics and gas sorted and arranged for the relevant regulatory boards to come and check them to issue certificates. The list goes on! Because of this great experience I literally call Irinel for all work that needs to be done. Not too long ago I needed a door hung and some silicone replaced in another part of the house, and I am happy to wait for him to be available rather than find someone else. Thank you Irinel and team!”
