To whomever it may concern

My wife and I have known Sylvester Mikolajczyk for more than two years and he has completed a variety of jobs for us involving carpentry, plastering, roofing, painting (indoor and outdoor), and plumbing, always to a very high standard. He is thorough in seeking the root of a problem, prompt in finding and designing solutions, speedy but meticulous in the work itself, very respectful of the house he is working in, and very tidy. 
He is exceptionally versatile but when he does not have the relevant experience or expertise (for example for electrical work) he has associates whom he can recommend and guarantee.
He is entirely trustworthy. 
Two of his qualities seem to me to be very unusual: his diagnostic skill and his aftercare. Not only does he like to work out exactly why things have happened but he points out other incipient problems. Having undertaken a job, he will return to check up on it six months later.
I have only direct experience of Sylvester’s work in our house in Clapham, but I have heard of the excellent work he has undertaken for others. 
My own experience as director of an institution where constant maintenance to an old building was of the utmost importance has made me acutely aware of the value of someone with Sylvester’s range of knowledge, his curiosity concerning causes, his great sense of responsibility and integrity.
I would be very happy to speak with anyone who was considering giving him further employment.

Sir Nicholas Penny, Clapham, June 2017


I have known Sylwester for over 5 years and he has done a lot of work in my house on a wide variety of jobs.
Sylwester is highly skilled and very competent at a broad range of construction/home repair/plumbing/electrical tasks both inside and outside the home and has done many jobs for us at our home.
Sylwester’s quality of work is high and all jobs he has done for us have been very satisfactorily completed
I recommend Sylwester highly

Mark Astley, Hampstead, January 2019
I have employed Silvester on 3 different projects involving various
tasks, notably tiling, carpentry and external fencing. I have no
hesitation in recommending him as a diligent, intelligent and creative
tradesman who can turn his hand to all manner of tasks and produce decent
Nick Evamy, Director, Brookwood Estates.
I was recommended Sylwester through a close friend. He carried out repairs to our roof terrace and some snagging around the house.
My partner and I could not be  more impressed.

His workmanship is excellent, his diagnostic skill incisive and his care second-to-none. He was also very understanding of our cats rampaging around his work – and of our paranoia about them getting out the front door.

His pricing, patience and honesty are admirable – and no task seemed too small. I would recommend Sylwester to anyone who asked, for any work. He is the best builder and carpenter I have come across in London, and I hope to employ him again.

Thank you Sylwester!

Michael Lesslie, Angel, London
