It's very expensive, uses subcontractors, and doesn't honor agreements. It makes a nice story on the website, but it doesn't translate into practice. It left us with a lot of damage and then plays hide-and-seek. In practice, the only contribution to the work is sending a very slick invoice.

Very expensive. The service contract is unclear. If you want to cancel it, you'll receive a hefty bill for the maintenance performed. Maintenance + call-out fee: €119.90 for just 15 minutes of work! The service contract costs €121.11 (less than €80 elsewhere).

Leaking boiler. Called in the morning and the problem was resolved that same afternoon. The costs were very reasonable. Other plumbers in my town of Papendrecht could learn a thing or two from them. I'll definitely call them again next time I need help.

Neat company, agreements kept and very helpful with breakdowns and maintenance.

A few weeks ago, I had a major problem. I needed a central heating pipe with a bent half-eyelet. I bid a few times, but nothing ever worked. Then I thought, I'll call Korevaar in Sliedrecht, and sure enough, I can come by the next day. I duly checked in at the counter, and a man from the office came right away to help me. I brought a sample, and sure enough, he bent it neatly and beautifully just the way I wanted. I was very satisfied. They always say that office workers are always left-handed. But no, not everyone is. Hats off to the man who helped me. Thank you very much, that's why I give Korevaar a 5*.
