Plumbing- 15 Nov 2025
Incompetent company. They were contracted to put a new shower cubicle in one bathroom and regrout and make good and regrout in another bathroom. This company are completely incompetent. We had to take out all of the grouting that they did as it was so poor and all of the sealant. It was clear that they had no experience of fitting bathrooms or tiling at all. They did not even seal the sides of the shower unit against the walls, so water would be able to run right out of the shower cubicle. They did not connect the waste pipe and water came straight through the ceiling. I would not recommend this company to do any work.

Extensions- 17 Jan 2018
A Total disappointment Ricky agreed to install a porch and roofing. He advised us to install new pvc doors agreeing to fit the roof after. This started mid November with a promise to be completed before Christmas. On his instruction we paid other workers to complete the preparation works and then the morning of the Job he sent a text message advising that he will no longer be able to attend the job. Thankfully we were able to find a local reputable roofer -plasterer-tiler who completed the work to a very high standard I feel very let down as I had put total trust in his promise to complete the work. Unfortunately based on this I cannot confidently recommend Ricky to a friend family, or anyone else.

Insulation- 14 Feb 2023
I placed an add in mybuilder.com to have my house fully insulated and received many replies including one from Sergiu. After meeting him I felt he was the best placed person to carry out the work as he was the most knowledgeable and seemed to know all about the various types of insulation and which one I needed for my home. He fully explained the procedure from start to finish was always on time and tidied up at the end of each day.His work is second to none and the price was very very competitive in fact much less then the big companies were asking.I am extremely happy with the job and the standard of finish. Sergiu is very police professional and trustworthy and I would have no hesitation in recommending him to anyone on here to carry out work in your home.
