The project I worked with him on his creation of a garden music studio from scratch including foundations and Additional soundproofing. Vladi helped at every stage of the build keeping it to budget and suggesting many effective ways of reducing the sound adding extra installation and helping with the design.

Painting & Decorating- 2 Aug 2025
Very disappointing experience with Ramon. Ramon came to view the property before we agreed on the scope and price of the exterior painting job. We had detailed discussions in person and over the phone and agreed on everything including price and scope. Despite that, after starting the job, he changed his mind about the agreed price and asked for more money — something he never flagged during the site visit. He painted part of the exterior and then left the job half done without any communication for two full days. There was no explanation or notice — I was left completely in the dark. It was promised that he would come back the next day as he needed some extra tools but after multiple messages being ignored and calls being ignored it was clear we were left in vulnerable position with a half painted house without any communication. The lack of professionalism, poor communication, and unreliability make it impossible for me to recommend him. I have CCTV evidence of our conversations.

Conversions - General- 28 Jan 2025
We were absolutely delighted with Lino and his services. He was incredibly patient , as our flat purchase was delayed. We required a total gutting off our flat, with new kitchen and bathroom, new flooring, painting, and all the rest. He had great communication throughout. He showed up on time with his team each day , and was so professional throughout. We went to Lino for advice throughout the process. He never said any of our plans were not possible- he always either said yes, or provided another option. This was such a great help. I would recommend Lino to anyone. We are absolutely delighted with our flat.

Emir did a good job. The company did a bathroom refurbishment after water leak, repaired the damaged ceiling downstairs and painted the room. Emir’s attention to detail is very good and he went the extra mile to do the job properly. I will recommend his services.

Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy

I charge 60£ for a home visit and quote. This is to cover for my time and the website fee attributed to each add. If the jobs goes trough, this cost will be included in the final price. Hi, I am Flo, your local handyman with a decade plus of experience. Putting up a frame or building up an house extension, I can accommodate both and everything in between. If you have a project in mind i have a decade plus of experience that could come in handy so let’s get in touch. Yours sincerely, Florentin.

We honestly can’t recommend Orland highly enough. He came in mid job after we got abandoned by some shady builders, and was just fantastic. Built us a wonderful bathroom in under a week - was polite, professional, arrived early and all his work was to a very high standard. Would definitely ask him to help with future projects!

Civico did a number of jobs for me, including two bathroom renovations where they installed a Japanese toilet and a hydromassage bath, as well as underfloor heating, electrical work and some really nice tiling. They were always reliable and easy to deal with, and the standard of the work was very good. Even after everything was finished, they were happy to come back and help with small things when needed, without charging extra. I would definitely recommend them for bathroom work, electrical jobs and tiling.
