Initially (3 years ago) kbane said that my project can be done quickly and for 50€, 500€ will be paid by the state if I did some prework
- next info, after 5 (!) months (after I did all the prework): project impossible, because the structure of my roof is too fragile.
- after giving up, I relaunched a question with some other professionals who all agreed that it’s possible.
- I invited Kbane once more, who agreed easily for laine de verre soufflé after even more prework
- finally it was fast and easy and efficient
- costs were with 650€ after tax much higher than initially
