Kitchen Fitting- 31 Jul 2019
To say Nick is just a kitchen fitter isn’t doing his work justice, he’s a fantastic project manager and craftsmen as well. When we first met Nick he took 2 hours of his time running through all the options which was when we realised we were actually quite clueless! Although we hadn’t hired him at this point his advice was invaluable. We assumed this would mean Nick’s professionalism would mean he would be very expensive, this was not the case and he was actually a little cheaper than the other parties who quoted. Once Nick started it became apparent that he and his assistant Chow to great pride in their work and worked hard to get the job finished as quickly as possible to the highest standard. They left the site spotless at the end of each day. The result is a fantastic kitchen and flooring which we are extremely happy with. We are already thinking about the next renovation piece in our home and would love to use Nick again. Thanks Nick! Niall & Hannah

Landscaping- 4 Oct 2024
One word to define this 'company' COWBOY builders. Numerous issues one after another. Had to get 2nd/3rd opinion on their work to make sure I wasn't being fobbed off. Conducted loads of research which meant left being uneasy especially as a large chunk of payment was made after only 1 day of work when in fact payment was due end of completion. 1- Underestimating material costs 2- Slabs off the walkway coming loose within 2 months of being put down 3- Ignoring attempts of rectifying the flawed job 4- walkway was meant to be clear of grass and strictly shingles but grass/weed still appearing. 5- Forgot to state ground levels would be raised then creating a lie saying I had been told 6- denying and ignoring the obvious Wouldn't trust the reviews being left here and definitely wouldn't use or recommend them to anyone. Have decided to give up on trying to get them to fix their shoddy job and find someone else to fix their mess Correction - you was aware & agreed with mat delivery

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.

John did a fantastic job of replacing a large sash window in our kitchen. He was easy to work with, and was very clean and tidy with the job. On top of that the price was very fair, particularly for the calibre of work completed. Would recommend!!
