Property Refurbishment London

Jonathan Marks / Lord Marks of Henley-on-Thames Q.C.
To Whom It May Concern
MG Professional Limited I have pleasure in giving Mariusz Gajewski an unqualified reference for his work as a builder and decorator. He has carried out work for my family over a number of years. He has always worked to a high standard and to our great satisfaction. For that reason, when we decided to refurbish our house in South Oxfordshire, we entrusted the work to MG Professional. This was a very substantial project. Before we acquired the house, it had been used as bed and breakfast accommodation and partly divided into flats. It had not been refurbished for many decades and needed substantial rearrangement. Consequently the interior was largely re-built and re-fitted. It was then completely re-decorated. The property was also entirely rewired and re-plumbed by others, whose work MG Professional co-ordinated with the building works. The project took some three years, including building an entirely new pool house from the ground to architects drawings. General Building worked in close co-operation with me as I project-managed the refurbishment, but he also liaised with the architects who were responsible for the design, and the engineers, who designed the detailed engineering solutions where necessary. Mariusz Gajewski work was always thorough, well organized and executed to a high standard. He supervised his team of up to 14 workmen with admirable skill. He was always willing to find solutions for difficult problems, “No Problem” being his watchword. MG Professional sourced all the materials and plant for our work and developed good relationships with our suppliers. Always eager to please, MG Professional is a delight to work with. Anyone lucky enough to have then undertake work for them has made a good choice.


I have been know Mariusz MG Professional for over 10 years. Mariusz runs an efficient and cost effective building company. His team is able to work both on small and big / complicated projects. His workers are tidy, polite and very trustworthy. Mariusz follows the project from the start to the end, giving always the right advice. The final outcomes of the works have been of a very high standard. I am very happy with Mariusz’s building works .

MG Professional Ltd is an excellent building company. Its success and character comes from its founder Mariusz Gajewski, a highly professional, reliable and skilled builder. Mariusz has been carrying out building works for me for over 10 years including, most recently, a complete strip out and refurbishment of a 2-bedroom flat. This was done on time, to budget and to a very high standard. Even other traders have commented on the unusually high quality finish. I highly recommend him and his company for building work, big or small.
