Isoal

We can highly recommend Isoal for floor and ground insulation. We were provided with clear information during the quotation meeting, also in writing. The work was carried out neatly on the agreed date. Due to the many pipes and cables and also because you had to pass under a foundation beam, these were not the easiest. Photos were taken for us so that we could clearly see the result. We are very satisfied with the result!

After a good explanation by Alfred from Isoal, we were able to quickly make an appointment for the insulation of our crawl space (house from 1987). He recently insulated the 49 M2 crawl space with Tonzon. He explained it well, works neatly, took photos for the subsidy application and is also a very friendly man. We are very satisfied and curious whether our house will become more comfortable, which we will probably only experience in the winter.

We came into contact with the Isoal company through our neighbors who also had their floors insulated. Same day admission visit and a quote with a competitive, realistic price. The work was carried out fully to expectations and satisfaction. Everything looks professional. Your home will be left clean. And, most importantly: you immediately feel what you invested in, namely warm feet and comfort. Assistance with applying for a subsidy is also provided. All in all, the Isoal company is highly recommended. Kind regards, Richard and Monique

Today Alfred from Isoal installed floor insulation for us. Alfred is a nice, calm man who knows his trade well. Alfred worked just as Alfred explained during the first conversation how the work would be carried out. He works neatly. Any mess that is created is neatly cleaned up when the work is finished. We received good answers to our questions.

I was thinking about floor insulation and heard from a friend of mine about Tonzon, its environmental friendliness and the way of working. An appointment could then be scheduled quite quickly. Ever since I met Alfred, I had the feeling that I was dealing with a professional. Step by step he explained the concept and how Tonzon insulation would work. The costs were very reasonable for me. After a day of hard work everything was ready. In the meantime, Alfred had taken neat photos of the work. The effect was immediately noticeable because the underfloor heating could immediately be turned down a few degrees. I can definitely recommend Tonzon and Alfred. Thanks for the good work Alfred.
