Loft Renovation


From the start to the finish of our terrace house loft renovation in Criccieth, Josh and his team of tradesmen were exceptionally friendly, accommodating, and professional. Their demolition, construction, and finishing work was the very highest standard and they provided lots of excellent ongoing guidance to reasonably overcome the inevitable obstacles you discover when modernising and improving an older character property in a town conservation area. They even co-operatated readily and effectively to allow myself and a handyman to complete many time-consuming and labour-intensive tasks ourselves to help complete the work to budget. Their site clearance and final handover after 3 hard winter months was exemplary, and they happily returned a few weeks later to do a few minor fixes. I would thoroughly and unhesitatingly recommend this local family-owned building and plastering firm for jobs of any size.

Insulating & Plastering


We were very pleased with the prompt response from Josh Mulholland when we asked for a quote for work on our apartment. The quote was clear and comprehensive and the subsequent work was of an excellent standard, carried out to the timing promised. We were also impressed by the level of communication throughout, especially as we live at some distance and so were not present when the work was done. We had regular texts and emails and photos of the different stages of progress. Once it was finished, all protective floor coverings were removed and the carpets left clean. We would definitely use the firm again and recommend without reservation. Thank you!

Floor Tiling & Renovation Works.


We have been very impressed with the quality of work carried out to renovate our house; Josh and his contractors were very professional and accommodating - the price charged was as quoted and we felt provided good value for money overall. We'd certainly have no hesitation in using Josh and his team again in the future.

Extension & Renovation


We employed Josh and his team after a competitive tender and interview process. The project was a substantial and complicated extension in a cramped site which had to be completed to a tight deadline. There were many aspects of the project that were not standard but Josh took the time to understand our requirements well so that he could communicate with everyone to deliver what we had hoped from. He managed his team and other trades well on site to bring the project in on time and on budget. Having done major building works before we were very pleased with Josh’s can do attitude and professionalism and we are delighted with the results of his hard work. Thank you.
