Hi!
We bought a 70s villa last fall and now plan for a sill replacement. Slab on grade with pressure-treated sills that smell. We've been in contact with a few different companies and started getting quotes, and although the price is, of course, high, it's all the additional things we don't quite know how to handle. This is our first house and so far we don't know much, so our questions might be somewhat simple and obvious to everyone but us
For example, what do you do with the fiber cable? It goes into the outer wall at the entrance, but we haven't found where it goes next. I assume you have to move it before the sill replacement?
The air source heat pump and electrical wires that hang low on the outer wall and stick into the ground (the electric cabinet’s wires), they are not easy to move, right? (The air source heat pump can however be unscrewed). According to one of the companies, you might need to call in an electrician if the sill replacers notice it's needed then and there, but that seems like an uncertain solution. We've had huge problems scheduling electricians for other things here, as they simply don't have time.
The last thing we are wondering about is the bathroom. It has a bathroom floor but no tiles, and it borders two exterior walls. Do you usually have to redo the bathroom if you replace the sills from the outside? One person we spoke to said that if the bathroom floor is attached in a certain way, it will get damaged when they cut off the exterior panel to reach the sills, and that perhaps it would be best not to replace the sills by the bathroom if it doesn't smell there (which we don't think it does, but it would feel good to get rid of all the bad sills at once...).
As mentioned, we are quite clueless about this, trying to read up and learn, but it's slow going and we unfortunately don't have a handy person to ask for advice

. So it's not so much about the sill replacement itself, we leave that to the experts, but we didn't quite realize how much might cause problems (we thought they were used to encountering fiber cables and electric cabinets since it seems like something everyone has, but that doesn't seem to be quite the case).
Hope someone managed to read everything and has some good tips on how to proceed
