Conversions - General- 20 Jun 2026
My partner and I hired Alonso and Alex to undertake a full renovation of our 3-bedroom house in SE8. Having received quotes from several other contractors, the moment we met them, it was clear they were clear communicators, approachable and dedicated to their clients. We’re incredibly happy with the work they did. The scope of work was highly varied, including rectifying historical damp issues in the lower ground room, external repairs to the roof drains and chimney, installing two new bathrooms, plus all the other internal and external work you’d expect from a full renovation. All of which was completed to a very high standard! They were always open to discussing and rectifying anything we weren’t completely happy with, or problem-solving whenever unexpected issues arose (which always happens when renovating a property of this size!). The team are lovely, trustworthy people who are a genuine pleasure to have in your home. I can’t recommend them highly enough.

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.

Restoration & Refurbishment- 25 Sep 2025
We were over the moon with our kitchen once Zihni and his team had finished. We had never used this firm before but we will definitely be using them again for future projects. Zihni is calm, knowledgeable, and went over and beyond in helping us not just complete our kitchen project, but in helping us move into a new home smoothly. We are also really appreciative of the rest of his team, as they were all so serious, professional and perfectionists. Zihni's communication was probably the single reason why the completion of our kitchen was such a success.

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.

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.

Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez
