This carpenter is a plywood maestro! My wardrobes are a testament to their craftsmanship – sturdy, stylish, and a definite upgrade from my previous cardboard chaos. Would highly recommend for a wardrobe transformation that's as solid as it is delightful. ⚒️👌 Top notch, class A stuff 👍🏻

Kitchen Fitting- 11 Oct 2018
Mohsen went above and beyond with our kitchen face lift. He did exactly as asked, to a very professional standard. Mohsen is very hard working, has high standards and was reliable. He also suggested ways to improve our kitchen, and corrected some previous poor work from other builders! We love the job and will definitely use Mohsen and his team again for future work.

Garden Maintenance- 17 Sep 2017
I hired DS Developments to completely landscape my small front garden. This involved clearing and levelling the area; moving and re-securing a bike shed; laying a patio and lawn; and a number of finishing touches. The area went from somewhat of an embarrassing eye-sore to an area of pride. One that several neighbours have already made compliments about. David provided a professional service from start to finish. His quote was more than I expected, but his knowledge and vision gave me the confidence to select his services. He provided a selection of options and stuck to budget; adapted well to new ideas/suggestions; and informed in advance where the cost would be impacted. He and his team also were as tidy and considerate as possible and I highly recommend their services.

Bathroom Fitting- 28 May 2025
I am extremely happy with the job Isac has done. We are so very lucky to have found Isac to do our home. At the time of the works we were expecting a baby and Isac worked night and day to make sure our home was ready in time for our sons arrival. Without him we would have been screwed. Isac’s work is extremely professional. He has high standards and is very skilled. He’s honest, direct and respectful. I now consider Isac as a friend. He’s come back a few times since the works to check in and is always on the phone is you have any follow up queries. I would recommend Isac to anyone who has work they needed done. Thank you Isac!!!

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.

Bathroom Fitting- 25 Nov 2020
Alex provided a great service. He came round on time to view the job, gave a detailed and competitive quote and built the bathroom exactly to spec. He was keen to ensure I was happy with all aspects of the installation with regard to both materials and workmanship and even carried out some small additional activities not included in the original quote. He was polite, hard working and very experienced. He also cleaned up the house at the end of each day. I am really pleased with my bathroom and would thoroughly recommend him to anyone.

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.

Roofing (Flat)- 24 May 2026
Martin came and saw the job promptly. His quote was a little more than another I had had but he made a couple of suggestions and generally demonstrated he knew what he was talking about so I chose him. The job was done quickly and well in a day. It hasn't rained heavily yet but the roof seems perfect. Martin did say that if there were any problems to call him. I am sure everything will be fine but it's nice to have that kind of customer service. Highly recommended!

Latest review:
Peter was the on-site foreman on our complete house renovation, which took just over a year. This included an additional ensuite pod bedroom in the roof and a side-return and extension to the kitchen. Peter was totally reliable throughout the project and thoroughly professional. Throughout this time we were living in the house with the children. He was always on time, managed the on-site team well and communicated clearly with us. His workmanship is high quality and he was also a stickler for checking the work of others and getting it updated if it wasn’t up to scratch. I have no hesitation in recommending Peter.
