For a while we have been thinking about getting some help with making decisions to improve the sustainability of our house (a 1905 town house in Utrecht, which definitely needs some work to be more energy efficient). Frank from Woondoktor was exactly what we were looking for – he took the time to understand our motivation, thoroughly investigated our housing situation (even reading through some old building reports we’d found), and provided clear and manageable advice, which we will definitely act upon (though perhaps not all at once!) Clearly a worthwhile investment (especially once you factor in the subsidy that you get back if you actually act on the advice). Thanks Frank!
