Giovanni Amormino da Silva Júnior2024-06-03I deeply recommend his services. They try to help whatever you need, work hard and care about any issues you might have after they finish.

Maria McGrane2024-05-29OS Holding recently completed a renovation of my kitchen/dining area and I couldn't be happier with their work. The job involved knocking down a load-bearing wall, installing steel supports, taking up the old floor and laying a new one as well as skirting boards. They also did the plumbing and electrical works, connected new radiators and did the painting to finish. The guys are very skilled in all aspects of their work and they are careful to fulfil all requests. They are also very tidy. I'm especially happy with the meticulous way the herringbone floor was laid. Vadim is easy to work with as he listens to what you say a a client and is always prompt to respond to calls and emails. I would have no hesitation in recommending OS Holding and I intend to contract them again when I get round to doing my attic!
Sabina Capozzoli2024-05-26Many thanks for the outstanding work carried out by OS Holding team during our recent renovation in our house. Their attention to detail and dedication to quality were evident throughout the entire process of demolishing partition walls and fitting tiles on the floors and stairs. The installation of tiles on both floors and stairs was completed to the highest standard. Additionally, the team maintained excellent communication throughout the project, keeping us informed of progress and any necessary adjustments. Their punctuality and respect for deadlines ensured the project was completed on time, which was crucial for our schedule. I highly recommend OS Holding for any construction or renovation needs.
Ann Rundle2024-05-12Vadim and his team are highly skilled and extremely hard working lads.

I am delighted with my attic conversion and have no hesitation in recommending OS Holding Ltd.
Rachel English2024-05-06Vadim and his team recently renovated by entire ground floor and installed a new bathroom upstairs. The guys did a great job and the price was very reasonable.
