Extensions- 24 Oct 2025
Whilst we didn’t go ahead with Dave and his team (only due to proceeding with a family known builder), I only have great things to say about Dave. He was brilliant from the start in responding to my job post, arranging an appointment and spending a good amount of time talking over my ideas. He was really impressive with his knowledge, advice and expertise throughout his visit and staying in touch after. I cannot speak highly enough of Dave - if you’re thinking about having an extension or renovation - do not think twice about getting in touch with him.

Restoration & Refurbishment- 9 Apr 2026
had a very disappointing experience with this builder. After paying approximately 95% of the agreed cost, the work was left incomplete, including key areas such as the media wall, kitchen, and bathroom. Despite the job not being finished, he repeatedly insisted on receiving full payment. Communication became extremely poor, he often failed to answer my calls or respond to messages, making it very difficult to get any clarity on progress or next steps. He was also resistant to feedback. When I raised concerns or asked for corrections to work that was already done, it was not well received. Partway through the project, progress slowed significantly. Delays were attributed to personal reasons which had not been mentioned at the outset. It also appeared that other jobs were being prioritised over mine, leaving my project unfinished. To make matters worse, he failed to return my house key and did not provide the electrical certificate from the electrician he had introduced.

Restoration & Refurbishment- 2 Oct 2024
I just wanna express honest with you I met up with Mr John on two occasions and I told him everything I want confirmed we confirmed the price he sent us a spreadsheet but later on confirmed a figure once that was done he said send pictures. I’ll get the items for you and will get everything done for you in a time which was originally 2weeks . Then 2 month and half later he ignore my calls very unprofessional and has outstanding task he left and still not even correct , I am not able to go in to all the details but I tell you for free how I’ve been treated for the last few weeks mentally draining and for example he said let’s get his electrician because he needs the person doing the work side-by-side and if I’m honest, they’ve done nonsense because the media where the plug is is not correctly positioned in fact, the TV does not go in properly as they positioned it in the wrong place they didn’t check where the TV was meant to go initially I have to sort this out myself.

Kitchen Fitting- 18 Oct 2022
If you need someone amazing to help install your kitchen, Przemek is the perfect guy for the job. He is absolutely brilliant at what he does, very precise, very communicative and super friendly. Not only did he do my kitchen, he also did extra things for me for which he didn’t take extra money. There were a couple of things that were wrong with the original kitchen design that was made for us, but Przemek picked up on these quickly and managed to tackle them really effectively and quickly. Another amazing thing is that if you choose Przemek, you won’t need to get a plumber or an electrician as Przemek does all of it, and he does it extremely well. I very very highly recommend Przemek for everyone.
