Excellent phone contact. The appointment was made immediately, same day even! Mark took time to explain what he would do and then got to work. Some documents I still had to look up, but he remained calm throughout. We had follow-up contact by phone. Everything was pleasant and relaxed.
I collaborated very pleasantly with Mark from Hollands Duurzaam. Everything was handled quickly and carefully with excellent service! I can definitely recommend Hollands Duurzaam.
Clearly experienced and skilled person. Friendly and tidy too, which is nice when someone needs to go through your whole house for an energy label. Also punctual and adhered to all agreements. A pleasant experience for us!
Very nice company with good communication. The website said energy label takes about 3 weeks but it was arranged faster. I would definitely have the next energy label assessed by this company again.
Friendly and professional. Clear communication and everything as agreed.
