Carpentry- 22 Oct 2025
We gave Joe what I thought would be a difficult job - replacing a non-standard sized door in a wall that's not straight, and the old door had warped because it was so close to the heat of the shower. But he was amazing! New door is solid and cut down to fit, and he even found a handle that matched all the others in the house. Work was done quickly and efficiently, and we were very pleased with the results. We are already talking to Joe about getting him back to do other jobs around the house, and I would wholeheartedly recommend him.

We recently had a loft extension completed along with wooden flooring throughout the house, underfloor heating installation, and a full silicone render — and we couldn’t be happier with the results! The team were an absolute pleasure to work with from start to finish. Their innovative and creative thinking really set them apart — they found smart solutions to challenges and helped us maximise space and style in ways we hadn’t even considered. What impressed us most was their attention to detail and how clean and tidy they kept the site throughout the project. It made a huge difference knowing the work was being done to such a high standard, without the usual mess and disruption. Whether it was a small detail or a big task, nothing was ever too much trouble. No job was too big or small — they approached everything with the same level of care and professionalism. If you’re looking for a reliable, forward-thinking team who take real pride in their work, I couldn’t recommend them more highly!

Based on architect recommendation, we contracted Alain on a private basis to produce structural engineering designs for our home renovation. He undertook a site visit and then produced structural designs to support a large number of elements related to new support beams, lintels etc. These have been iterated with the architect and the process has been very smooth. He was very responsive and nice to interact with. Wouldn't hesitate to recommend as a structural engineer for the type of project we undertook (loft conversion, new pitched roof, new openings within walls and ground floor open plan conversion)

We hired Omer and his company for a rear extension and internal remodelling/refurb. We had some firm ideas and some more flexible ones that we developed as we went along. Omer was great help in finalising these ideas, always ready with helpful suggestions and was always flexible and good humoured about the changes (even the later ones). He was also open to take on tasks that were perhaps somewhat outside their regular remit (installing equipment, decorating etc.) The project was started and finished on time. Omer communicates well, excellent at planning and organising and is very reliable. Omer kept us informed about the project at every step and actively sought our involvement. Any problems that did arise he was open about, flagged them up early and came with a proposed solution. He was also very flexible working around the delivery dates and deadlines of our other suppliers for various other elements of this project. The project was finished on time and within budget (except for agreed changes). The work was carried out to a high standard. We are very happy in our new home, can wholeheartedly recommend him and would happily use him again.

I recently had a bathroom and utility room refurbishment and am very pleased with the results. Hanif was fantastic, coming up with solutions to transform our bathroom from a tired room to a modern and stylish space. There were no problems that he wasn't able to fix and was great at making sure we ended up with the refurbishment we wanted.

Martin undertook a comprehensive renovation of my entire house, incorporating rear and side extensions, a loft conversion, and a rear pod addition. The project involved stripping the property back to its bare walls, reconfiguring room layouts, and installing entirely new bathrooms and kitchen facilities. Additionally, Martin oversaw the revitalisation of the garden area. Martin's professionalism and meticulous attention to detail were exemplary throughout the project. I am exceptionally pleased with the outcome of the work. This is not my first collaboration with Martin; I previously engaged his services for a complete house renovation in 2021.
