Bathroom Fitting- 22 Apr 2023
Younger brother Anti was a professional and I would hire again but beware of the elder sibling as his workmanship his poor, here is a list:- 1) the cupboard fitted under the stairs was misaligned and the hinges are loose. Paint job was poorly finished too. 2) cupboard fitted across the boiler was all bent. Anti came and fixed it. 3) varnish across door and skirting boards were done once and therefore have an uneven spread 4) the floorboards did not have enough glue placed in certain areas so it creaks 5) grout in some time are missing 6) really poor sealant work on the bathroom 7) broke my £2000 TV and then hid the evidence. I only found out after placing the furniture back in its place. In contrast Anti did a good job in fitting the radiator. If you can Illicit promises of Anti only completing the job without the older the brother then go for it or else give them a wide berth.

Extensions- 29 Aug 2021
Communicated well at the start with reasonable cost. work was done well but the finishing was not so great as expected. The end cost was very expensive. Charged by the hour, the team were very slow which was upsetting to see me pay for time where they sat around not doing much. Ensure to agree fixed price. Communication after job is poor, double glazing has warranty which now not being able to communicate with kostas having to pay to get things done that should be covered in warranty. Central heating give huge problems. Do not use for big jobs

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.

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.
