"We used DeMa Construction last year for remodelling our kitchen & dining room & have just had them back to upgrade our lounge with the construction of a Media wall with the associated electric work, the whole room was also replastered & decorated. The quality of the workmanship is outstanding & Marcin is a perfectionist. He is extremely polite, knowledgeable & hard working & is probably the tidiest builder in the world !!! All in all I am extremely pleased with the whole experience & have recommended him to friends & neighbours."
