Marcin gave us a very detailed quote, allowing us to choose which parts of it we wanted done, in line with our budget. Tomasz was extremely efficient, and got the job done 2 days before the expected finishing date. Marcin came by every few hours every day to check the progress. The finishing was of the highest quality, they left everything spotlessly clean, and we are extremely happy with the result. We wouldn’t hesitate about hiring DeMa Construction again whenever we might need further work done in the house. We can definitely recommend them.

I wholly recommend Marcin and his team to anyone looking for a company they can rely on and ensure that work is carried out to their wishes for a reasonable price. We initially called Marcin round with a rough outline of what we wanted, but he worked with us to flesh out the ideas and then constructed a quote around our wishes. They started work promptly, and are on track to finish the job to a very high standard. We met weekly with Marcin before work which was great as it meant we could ensure that all the small details were looked after. Thanks Marcin for your work so far!

Excellent work from Marcin and his team. They were great from quoting for the assignment through to finishing the job. Very courteous, clean in all their tasks and always open to discuss the task in hand. A really quality team.

DeMa are a fantastic firm, I wholeheartedly recommend them! Our build included several complexities, including the need for a sewer build-over and relocated man-hole, an awkward retaining garden wall, chimney removal and demolition of a small section of a structural internal wall. Dele and Marcin were always able to find the most efficient/cost-effective solutions to enable the design to be viable for us. The builders were on site every day from 8am and worked tirelessly; the quality of the finish is also excellent. Minor post-build snagging is now complete and I’m 100% satisfied. Go DeMa!!

Extremely helpful, skilled and friendly service. It was my first renovation project and my numerous questions, texts and emails where always promptly answered. Would highly recommend.

Marcin and his team have been great. I was kept informed every step of the way and he made sure that everything was carried out exactly to specification. Friendly, helpful, and best of all, a born problem solver. I’m hugely pleased I found DeMa Construction Ltd here on Checkatrade.

We had a fully concreted over, dated back garden with a huge ugly shed. We came up with quite a complex design of integrated planters, seating, decking and shed, with no concept of how difficult this would be to do. Marcin’s team did an unbelievable job. It looks much better than we thought it would and they suggested and added some practical additions like drainage. They also adjusted a shed we bought to fit perfectly. We’ll try to add pictures as it looks great. Would recommend Marcin and team for any work as we asked them to our garden after great work in the house.
Mr Juergen Specker 8 feb 2015
Fantastic builders, great attention to detail, lots of valuable suggestions during planning and execution. Marcin and his team kept us informed at all times regarding the work and were very polite, even our shy cat liked them! We are extremely impressed with the quality of their work, and definitely plan to use them again. We would highly recommend DeMa Construction.

We feel extremely fortunate to have found DeMa Construction. They have been incredibly helpful and through their initiative we got council permission to increase the size of our kitchen extension significantly. They care about their work, pay every attention to detail and are friendly and fun without being intrusive. It is a pleasure to give them full marks!


Everybody knows that the kitchen is the heart of any home.  Marcin Matysiak transformed my 30 year old run-down, tired and considerably outdated kitchen into a sleek, contemporary luxurious area which exudes subtlety and elegance.  Marcin is a very conscientious, reliable and professional kitchen fitter whose attention to detail is second to none.  His rates are also very competitive.  From assembling kitchen units, to decorating and from tiling, to plumbing as well as electrical requirements, his versatility is limitless.  Marcin brought my dream kitchen to life.  I now have a stunning and sophisticated stylish kitchen offering a modern look with a simple but evocative finish.  I am so grateful to Marcin for his invaluable workmanship.

Re: Reference in support of the work of Martin Matych
Martin Matych has just completed work on my ground floor WC, main bathroom and en-suite shower room. I am exceptionally pleased with the quality of work done and the way that the work was undertaken.
As part of the project within my home, Martin provided a complete professional service from design and measuring to completion of works. He had a keen eye for detail and ensured that his work was of the highest standards. He demonstrated high levels of professional skills in the works completed, and was able to problem solves unforeseen issues with competence. He was able to provide a range of solutions and always kept in consultation with me to ensure that I was happy with the choices and outcomes. I was also impressed by the way that he took care within my home to ensure the least amount of disturbance and mess.
He worked hard and long hours to ensure that the project in my house was completed in the least amount of time, with the least disruption. This was particularly important for me as I often had to work at home whilst the work was being completed.
I appreciated Martin’s honesty and integrity in his services and his work. He took pride in the quality of his work and, moreover, ensured high levels of customer satisfaction. He also maintained a very good sense of humour, despite the long hours that he worked.
I have been so impressed with the works completed in my home that I will be asking Martin to undertake work on my kitchen later in the year. Photos of completed works have been taken to show the high quality of finish. I unreservedly recommend Martin Matych to complete any domestic building and renovation work.


Yours faithfully,

To whom it may concern.
I am very happy to recommend Martin. He was largely involved in the £60k refurbishment of my house in 2008, the house was derelict and involved completely stripping out the house. During the refurbishment work of my house, Martin showed himself to be reliable and hard-working. Martin’s specific tasks which were excellently done were
• Installation of new steel beams
• Building of new partition walls.
• Installation of plasterboard to all ceiling and partition walls
• Installation of replacement stairs
• Plumbing for hot and cold water
• Plumbing for central heating but not installation of boiler.
• Installation of kitchen and tiling
• Installation of two toilets, one shower and a Jacuzzi bath and all the associated tiling
• Installation of interior door and all the associated finishes
• Installation of skirting. I am very pleased with the finishes of Martin’s work and I will always recommend him for his good work and more importantly his honesty

Yours faithfully
