Janco built a beautiful extension for us. From the initial meeting to the final touches, it was a truly wonderful experience. Janco excels in precision, dedication, neatness, and enthusiasm for turning your building dream into the perfect picture.

Janco and his team completely renovated our home in Naarden. We are thrilled with the results. The work he and his team did was excellent. Nothing was too much trouble, and a promise is a promise. The guidance was excellent, and Janco was incredibly helpful and patient with any questions. Whenever we called on him for advice, he was always ready to offer guidance. If an answer wasn't possible, the answer had to be: "Well, that's taste" 😊, and even then, we managed to find a solution. The construction site was clean every day. This was great for us, but also for our neighbors. We've heard from them that they also speak highly of him. In short: A great contractor whom I highly recommend. Thanks, Janco!

Janco coordinated a complete renovation of our 1920s home. We had a fantastic experience! Not only was the work done perfectly, but the communication was excellent, and it was completed within the agreed-upon timeframe! Communication about additional work was also transparent, with no nasty surprises. We also really appreciated that Janco and his colleagues actively contributed ideas and made excellent suggestions about how to renovate the house in its original style. Highly recommended!

I can only echo the reviews of the others. Janco and his construction team delivered expert work on the renovation of our attic. Honest, pleasant, and quick communication, proactive thinking on the best way to furnish the attic, true craftsmanship from all the men, and everything was left tidy after every workday. In short, highly recommended!
