Worth it to replace insulation and air seal?
Is it worth it to replace 45 yr old double layer insulation baffles for new ones and air seal? I recently bought a house built in 1980 and it has original insulation. House had somewhat of a mice issue that I have been dealing with with snap traps and get 1-2 per week. I recently did a sewer pipe repair in attic and noticed the baffles are still plump and sitting fine but curious if this is worth the cost to replace and air seal and clean up mouse droppings? We plan to be here for a bit so curious if investment is worth it. It’s a 2 story 2k sqft cedar sided house.
I understand it’s a difficult job and would get a few quotes but was also thinking of doing it on my own. Maybe doing like a 1/4 a weekend to space out the work and getting materials. Assuming quotes will be between 3-5k.
