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.

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)

Extensions- 27 Aug 2025
Dunster House Garden Office (5m x 2.5m build) We are absolutely delighted with the garden office that Michal and Lenka built for us. From start to finish, their expertise and attention to detail shone through. They guided us with thoughtful consultation, listened carefully to our ideas, and delivered a finished office that is both beautiful and practical. Their work ethic, professionalism, and friendly approach made the whole process stress-free and enjoyable. The quality of the build is outstanding, and it’s clear they take great pride in what they do. This was a 10/10 experience, and we could not recommend them highly enough! We also used them again for another job to build install a Pantry; Michal and Lenka recently built and fitted a bespoke pantry for us using Howdens units, and we are beyond impressed. Their knowledge and craftsmanship are second to none. They made excellent recommendations throughout the process, ensuring the final result was exactly what we needed.

I had the pleasure of working with Romeo and his team on my kitchen renovation, and I couldn't be happier with the results! From start to finish, his work was great. The kitchen looks fantastic, and they even finished the project ahead of schedule! Romeo and his team were very professional, always on time, and always kept me updated on the progress of the project. They also kept the flat clean and tidy every night, which made it much easier to live in the flat while the project was being done. I highly recommend them to anyone looking for a kitchen renovation!

Conversions - General- 14 Jun 2022
Wayne contacted us about a job I had posted to re-render and redecorate the pillars at the front of our house (they were badly in need of repair). From the start and throughout the job Wayne's communication was outstanding - he let us know exactly when he was coming and always arrived on time (the job had to be spaced out a bit due to weather so a constant dialogue was needed). Value for money we believe was very good. Wayne even did some small tidy up extras for us free of charge so very happy with the price. As to the results, we're very pleased. Out pillars look fantastic and are exactly what we wanted; our only problem now is that the roof above the pillars now looks a bit shabby in contrast! We would not hesitate to recommend Wayne and will certainly look to hire him again in future.

Conversions - General- 5 Mar 2025
As a new homeowner, I embarked on a renovation project for my four-bedroom, 1920s semi-detached house. The renovation involved transforming the ground floor into an open-plan layout by removing structural walls, installing reinforced steel joists (RSJs), and replacing the existing flooring with vinyl tile (LVT). Additionally, a new kitchen was installed, along with underfloor heating and air conditioning. Kaiser arrived at the site with a notebook, took precise measurements, and consulted with the structural engineer. He was transparent about the scope of work included and excluded, and his quote was the lowest when all quotes were normalized to include or exclude materials. Throughout the project, Kaiser maintained complete transparency, and no supervision was required. Communication was always prompt and effective. The renovation was completed on time, and I wholeheartedly recommend Kaiser. I am confident that you will not be disappointed by choosing Kaiser.

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!
