"I recently had my kitchen completely ripped out and replaced by DEC-Approved and I am so pleased with it! I can't recommend them enough. Friendly, reliable workers who turn up on time and when they say they will. As messy as replacing a kitchen is, they were as tidy as possible during the works and cleaned up when they were finished. The kitchen has been done to a very high standard and I haven't been able to find fault with anything, it's perfect! I've no doubt I'll be using them again for any other work I need doing professionally."
