Can't reply to GP anymore, so I'll reply here. Over here it is actually pretty common, it's currently a huge pain to find contractors (plus they're getting more expensive by the day). We talked to a lot of people who about what they did, and I have two findings: 1. Sustainability (of materials) is usually a lesser factor, most people seem to care most about the energy saving and to some extent the improved comfort. 2. Most people do these improvements over a long time, e.g. do the roof when they can afford it, save some money (or pay off the loan) and do the windows,... - so that might take up to a decade to get the house up to a decent standard. Doing "all at once" is more rare, and those people are surprised when we tell them we plan to do as much as possible early on, as we can then earlier realize the potential savings. btw, I envy your draftfree house ^^"
