Extensions- 30 Nov 2020
A really excellent set up of builders. Peter was great in evaluating the work and what we needed done. Sue was clear in her communication on costs, and then execution of the works by Taras and his team was superb. The extension was built in fantastic time-frame, and the end result is great. The work-ethic of the builders is what really makes them so good. They are on-time every day, and relentless with working hard each day.

I charge 60£ for a home visit and quote. This is to cover for my time and the website fee attributed to each add. If the jobs goes trough, this cost will be included in the final price. Hi, I am Flo, your local handyman with a decade plus of experience. Putting up a frame or building up an house extension, I can accommodate both and everything in between. If you have a project in mind i have a decade plus of experience that could come in handy so let’s get in touch. Yours sincerely, Florentin.

Conversions - General- 28 Jan 2025
We were absolutely delighted with Lino and his services. He was incredibly patient , as our flat purchase was delayed. We required a total gutting off our flat, with new kitchen and bathroom, new flooring, painting, and all the rest. He had great communication throughout. He showed up on time with his team each day , and was so professional throughout. We went to Lino for advice throughout the process. He never said any of our plans were not possible- he always either said yes, or provided another option. This was such a great help. I would recommend Lino to anyone. We are absolutely delighted with our flat.

I recently had extensive work completed in my flat by Vas, and I couldn’t be happier with the result. The service was excellent from start to finish. Not only was the quality of the work consistently high, but the whole experience was smooth and stress-free. What really stood out was Vas’s level of skill and versatility. Every aspect of the project was handled with care and professionalism — from plumbing and new water heating pipes, to new electrics, installing a new kitchen, laying a beautiful wooden floor, renovating the bathroom, and even replacing doors with a sliding door system. Each element was completed to a very high standard. On top of that, Vas was friendly, proactive, and easy to communicate with throughout. Nothing ever felt like too much trouble, and it was clear he takes real pride in delivering great results. It was genuinely a pleasure to deal with Vas, and I would highly recommend his services to anyone looking for reliable, high-quality work. Thank you again!

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.

Extensions- 8 Dec 2017
We couldn’t be happier with the professionalism and quality of workmanship from REA Construction. The project was delivered within budget and on time. We lived in the property during the work and we, our neighbours and the site were always treated with the utmost consideration. There were almost no hitches and, when they did occur, they were dealt with immediately and thoroughly. Our project team, led by Kristjan and Besi, were universally hardworking, organised and produced work to an excellent standard. Communication is great, the people are wonderful. Renato was someone I felt I could trust from the moment I met him and he never let us down. He and everyone at REA genuinely care about what they do and that their customers have a happy experience. We certainly did and would have no hesitation recommending them to others.

Charlie and his team did a great job on our 2 bed flat refurb in Brixton. They were able to start straight away, and were always quick to double check plans and decisions before completing the project in great time. Charlie was open and transparent on all costs and made himself available to answer questions and give guidance on many parts of the project. Highly recommend!
