Vonk Isolatie B.V.

We had the floor and wall insulation done by Vonk Isolatie. Compared to other providers, this company seemed the most reliable and knowledgeable. Our wishes were really listened to and we were extensively informed about the possibilities. The work was carried out very neatly. Very knowledgeable and pleasant to deal with staff. Good communication. Thank you very much.

I have a very positive experience with this company! Despite shells in my crawl space, the "TonZon" insulation was installed a year ago, which is often refused by other companies due to the sharp surface, after which I used significantly more economical heating in the winter (underfloor heating). I was most surprised when I asked to take a look at my daughter's house because there was water in the crawl space and there was a lot of mosquitoes. The (foam) insulation turned out to be in order, but the crawl space was pumped out and a cover was made over the bottom for a reasonable price, after which it now appears that the mosquito problem is completely over, a huge relief for my daughter and grandchildren! In short, a top company, with service that you don't often see anymore!

Multiple failures to show up for an appointment. Friendly, but unreliable. I have better things to do with my free hours than wait for you and never hear anything.

The wooden beams under our house, which is almost 100 years old, were in bad condition and were replaced by new ones and tons of solar insulation was installed at the same time. Removed the old floor on Monday, put in new beams on Tuesday, closed the floor on Wednesday and put on the new laminate on Thursday. All carried out by Vonk Isolatie. I can - warmly - recommend them. Very nice, decent people around; the work is done cleanly and quickly. Literally all waste is taken away. We work with the latest tools and techniques. A 10.

Friendly staff and nice that it could be realized at short notice
