Bathroom renovation and K-Render to Front and Gable of house Part 2
10Verified ReviewEMa Construction was recommended to us, and we could not have been happier. What a fantastic company to do business with, honest, trustworthy, reliable and true to their word. Communication from the start has been professional, honest and open with regular updates on the progress and what materials have been used. Initially Marcin and Thomas transformed our bathroom into an amazing wet room, tiling from ceiling to floor. The workmanship is of the highest standard and completed within the timescale given. They are so friendly, polite, courteous and respectful and it is very clear they take... their craft and profession very seriously and take pride in their work and the finishing touches. They arrive at 8am and leave around 5 and upon your return home you would never know they had been there cleaning up after themselves. We were so pleased with the work we asked them to K-Render our house, again what an outstanding job. All we can say is you will not find a more genuine builder than Marcin and his team Thomas and Adam and we will certainly use them again and recommend.

10Verified ReviewMarcin and his team fitted 2 new bathrooms, inc. Removing of the old ones, refurbishing the rooms, drainage, fitting of the new suites, tiling and decorating. As people with very high standards we are always nervous of using contractors after having some previous poor experiences. Needn't have worried, Marcin's workmanship is of an exceptional standard with great attention to detail. Very happy with the works. The team are also friendly, polite and professional, a pleasure to do business with. We are continuing to use them for a large extension fit out and other works. Would highly recommend.

10Verified ReviewFantastic service, on time completion, on budget. Recommended. From initial tender, to managing building control, and specialist trades, the team at Dema delivered. They incorporated our requests for change and delivered a fault free, quality extension. A pleasure to have around and their genuine care in all aspects shone through. Other trades commented on how good their workmanship was. We will use them again for further works, even if we have to wait.
