Kitchen Fitting- 19 Mar 2024
Highly skilled, professional and courteous Nik responded quickly to the job request and promptly confirmed the appointment for doing the work. During the initial discussion he did not try to push for un-necessary changes. He completed the work as per the requirement even going out of his way to source parts that were not matching. The work was fiddly and took longer than expected but Nik was professional about it and persisted with it on the committed times and cost. On completion, Nik tested everything was in order and left everything neat and tidy. We are looking forward to working with Nik again on the next set of changes in our house.

Extensions- 9 Nov 2021
I had a great experience hiring Victor & Co. They built a Rear Garden Extension in my house with excellent standards and finishing. Also they have done everything on time, which I know is quite difficult. I met Victor, the director of the project, every week to discuss the progress and any alterations to the original plans. He was great at explaining all the options and delivering the work. All the builders were very polite and you could see that they were very well organised with all the tools and building materials they brought to the house. When there were minor delays they were happy to come on weekends to catch up with the programmed finishing time. For the level of noise you could expect a building site can generate they were incredibly quiet. Last and not least, the quote I have from them was one of the most competitive ones I found in the market, so I can definitely recommend this company to anybody that is planning a big project.

Couldn't recommend Domi & Emile enough. They have great building knowledge and kept us informed and up to date throughout the whole building process. The job was finished to a high standard and they even came back free of charge to tie up a few snags a few weeks later. Great builders and a great team!

Extensions- 25 Jul 2023
Vini and his amazing team became part of our family for the months they were working on our house! Attention to detail and great communication was a top priority for me before starting our large scale renovation, and they delivered above and beyond on every front. Vini’s team helped transform my vision into a reality - they weren’t thrown or intimidated by any of my crazy/creative ideas, and were equally ready to advise and bring constructive ideas of their own to the table, based on their years of experience. We would highly recommend Olaj Brothers as trustworthy, professional and highly skilled tradesmen.

Very happy with the work Gesti did for us. We just brought our first home and the ceiling honestly wasn’t looking the best. Lots of cracks and slightly warping. Gesti was able to come in and secure all the cracks and plaster the entire ceiling for us. He did an amazing job. Will use him again I highly recommend. !!

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.

Painting & Decorating- 3 Sep 2024
Great, reliable contractors. Had a full flat repaint job with some minor repairs (blinds fixing, handle replacement). Claudia was very efficient and responsive in communication. All was arranged pretty quick, appointment attended on time and kept to time schedule agreed. Had done a great job with repaint and provided reasonable rates. Also helped out with few minor repairs so I didn't have to get someone else. Very happy with the service , will certainly hire again. Thank you guys.

We did a lot of research ahead of our loft build, and spoke to customers of the companies we looked at. We were impressed with Toma and her team from the outset, especially in terms of clarity and communication. We sat down with the project team at the start and walked through the week-by-week plan for our build, then a whatsapp group and weekly meets meant we knew exactly what was happening throughout. Our endless questions were responded to swiftly. Additional optional trade-ups (eg top-hung windows, larger bathroom window etc) were discussed and explained with context, sound advice (and clear pricing where nec) but always still optional. Toma's communication with the teams also seemed strong and continuous, with materials always arriving in time and ahead of when needed, no down-days etc - and importantly, the teams all seemed happy and were just lovely people to have around. I realise with hindsight too that the team's care and workmanship really put them a cut above many others in my area and the project remained on schedule. I wouldn't hesitate to recommend ICS for the whole package and in fact we've also chosen to use them again for a kitchen extension.

Carpentry- 24 Jan 2021
George came to do up our hallway. He laid flooring and installed new spindles and a handrail on our stairs too. He did a wonderful job on the whole lot and we were very happy with him. We were awkward and changed our mind on the first laminate flooring that I had picked out online, he ripped it up and started again with the new flooring we picked and it was no hassle to him. George is a lovely fella, trustworthy and professional. Would highly recommend

Plumbing- 8 Jul 2026
I asked Gareth to come and help identify the source of a leak as I wasn’t totally satisfied with the first opinion I had received and wanted a second opinion. He was extremely knowledgeable, very down to earth and found out what the problem was with relative ease. He has an easy confidence of someone who knows exactly that they are doing. I wish I had used him first time round.
