Restoration & Refurbishment- 14 Oct 2025
Peter and team did a brilliant job refurbishing our kitchen. He organised building control sign off for knocking down an internal wall. He sourced new glazing for us and designed and built a custom bench seat. He assisted us with ordering the right units for our kitchen. He was great at problem solving along the way e.g. cutting cornice to fit tricky corners. The team were courteous and left our house tidy at the end of each day.

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.

Latest review:
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.
Poynts Works Ltd
Rating: 5 out of 5
Extension Builder in Wallington
I'm an ARB Registered Architect with 18 years' experience designing residential extensions, renovations and conversions across London. I work directly with homeowners from the earliest ideas through planning permission, Building Regulations and, where required, construction on site. Every project begins by understanding how you want to live. Using sketches, 3D models and visualisations, we can explore different options together before you commit to building work, giving you confidence that the design is right for your home and your budget. Once the design is agreed, I prepare the detailed technical information needed for construction and remain closely involved throughout the build, helping resolve questions on site and ensuring the original design intent is delivered. If you're considering extending or renovating your home, I'd be happy to arrange a free initial conversation to discuss your ideas, the likely planning implications and the next steps.

Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!
