Bathroom Fitting- 20 Jan 2023
We highly recommend Mario & his team. They fitted a new kitchen & bathroom to a really high standard within a short, timeframe. They work hard, are friendly, professional & honest, my neighbour even commented on how considerate they were! Upon first meeting Mario we were impressed by how organised he was. He arrived on time with the description we’d posted on my builder & went through it methodically. We had A LOT of questions! He answered all of them & didn’t rush us. We received a competitive quote within a day as promised. It included everything we discussed & he quickly answered our follow up questions. We wanted an accurate idea of the cost of electrical work & Mario arranged for his electrician to come & inspect/quote before we’d appointed Mario the job. Our kitchen & bathroom is complicated, with lots of difficult angles. Damp, unlevel floor, unlevel windows, a low ceiling were uncovered in the bathroom. Mario did well to identify solutions, giving us expert advice. Pipes were neatly chased into the wall. Underfloor heating & LVT, tiling, grouting & painting all done to a very professional finish. He kept us informed of progress, checked our preferences & was patient when we had supply delays, finding ways to ensure the job finished on time enabling us to move from our temporary accommodation back home in time for Christmas. He promptly fixed some minor issues after the job finished. We highly recommend Mario & would use him again.

Landscaping- 7 May 2026
“We recently had our landscaping redone along with new turf installation, and the results were excellent. The team was professional, punctual, and paid great attention to detail from start to finish. They completely transformed the garden, leaving everything neat, tidy, and looking amazing. The new turf was laid perfectly and has already made such a difference to the overall appearance of the space. Communication throughout the project was clear and friendly, and the workmanship was top quality. Highly recommend to anyone looking for reliable and skilled landscapers.”
