This year, I entrusted Demir with the complete renovation of my house, and I can only say: excellent workmanship from start to finish! From the renovation of the kitchen, bathroom, and toilet to all the plumbing and electrical work involved, everything was carried out with the utmost care, precision, and craftsmanship. The team works efficiently, is proactive, and delivers on its promises. What I especially appreciate is that they remained available for service and aftercare even after the renovation. I'm incredibly happy with the result and would recommend them to anyone without hesitation! A reliable company that truly takes renovations off your hands.

Demir Installation Process B.V. did a great job. My vitalizer was installed neatly and professionally. Communication via the app was also excellent. Very happy with everything!!!! I will definitely contact you again for projects in the future.
