Tiling- 11 Jun 2025
I hired for just for bathroom and toilet tiling, However due to the diligence, attention to detail, honesty and work ethics of Muro construct, I hired him to decorate my entire house, this includes everything form stripping wallpaper and painting, floorings, tiling, fixing doors, putting up all my new furniture including a very compl bunk bed for my children room. This builder works really hard and time efficient. He has helped transform my house into a luxurious living space and I am not exaggerating when I say that the price is very fair, I have had three times the quotes for less the quality. I will be using the builder for future jobs.

Carpentry- 8 Apr 2026
I’m really happy with the work carried out. He came in to fix my steps after a previous builder had damaged them and left them unstable, and the difference is night and day. Everything now feels solid, secure and properly finished. He also fixed the skirting boards and installed my desk, all to a very high standard. What I really appreciated was how professional he was throughout and the advice he gave along the way, which showed real experience and care for the job. Overall, a really high-quality finish and a great attitude. I wouldn’t hesitate to recommend him.

I recently hired LLC Projects Limited to refurbish my ground floor and add a new bathroom, and I couldn’t be happier with the results.

Extensions- 30 Sep 2025
Overall, I’m very pleased with the work Marin has carried out for us and I’m currently in the process of instructing him to do more work. Marin built a high spec cedar shed for us with electrics and plumbing, some brickwork and laid composite decking. Marin came across, honest and reliable, which in itself is rare. He was on site most mornings to make sure his tradesmen were on the right tracks. Like with a lot of these things there were some issues along the way and I was highly impressed by Marin’s ‘no quibble’ approach to rectify any problems. I myself have a high attention to detail and am quite indecisive (nightmare client) and Marin was happy to work with me with changes to the project without incurring extra costs.

Bathroom Fitting- 20 Sep 2017
We hired Luca for a job that involved a variety of work across our entire flat. Being totally new to renovation work and having been stung by other builders, meeting Luca was a breath of fresh air – he was friendly, helpful and honest. Luca did an great job for a very reasonable price. He’s fairly new to contracting bigger jobs, but he’s got a lot of previous experience as a tradesman and his plastering in particular was perfect – we’ve had loads of compliments on the quality of his walls and ceilings. He was always on time, always communicated with us fully, and was a pleasure to have around the flat. He made a real effort to keep disruption as minimal as possible and was very patient with us about stuff needing to be moved from one place to another. It wasn’t the easiest job and there were a couple of problems and extras, but Luca takes a lot of pride in his trade and worked extremely hard to keep us happy. We had a couple of plumbing issues arise but he went well above and beyond to resolve them, coming back for 2 days after the job was due to be finished to make sure that everything was working properly. This is far more than we expected, and we did really trust that Luca wasn’t the sort of person that would leave anything unfinished. We’re so chuffed that we met Luca and with the excellent work he did, and would love to work with him again. Luca is going to go on to big things, so if you get the chance to hire him now, we'd recommend him without hesitation.

Painting & Decorating- 24 Feb 2020
Quite literally the worst tradesman I have ever worked within 25 years as a property developer! He came and quoted to paint my house (a good price I must say), little did I know that this meant he would spray everything that he can see, not prepare the surfaces by sanding them down or protects things. This included door handles, hinges, radiators, alarms sensors, tiles and my own furniture and cooking utensils. First time I confronted him about this he said that we would clean everything, and we agreed to carry own. However, it became apparent that we was doing the same as previously discussed. have paid hi 66% of what was agreed, I quickly realised that the damaged he has caused was going to cost me far more and I told him to leave. The next day he turned up at my house with his wife demanding the balance which I refused to give him, they were both shouting outside my house, threatening to call the police. I eventually agreed to pay the 50% of what was left, just so that they would leave. However, even once he had confirmed writing his acceptance of this, he walks over to me and threatened me one final time, saying that he will take me to court etc, there is god and he will see to me! I advise to stay away from this person, better to pay a little more and work with professionals who don't agree with one thing and do another. He paints using a spray, which means you can not touch anything up and he quite literally paints everything he sees!!

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
