Welcome! Here are some tips for using this forum.
another question for homeowners
I wou;ld suggest you contact your local energy supplier and ask if they or someone they know of conducts energy audits of residential homes. Once you have this information, have a energy survey of your home done and find out where you are loosing the most heat/ cooling dollars from your home.Then ,armed with this imformation ,contact reputable contractors -- the ones on this site are good or Dan would not let them list and have some quotes done. The estimate ,having been done by the energy people ,will allow you to ask questions you already have the answer to and you can judge the responses you receive from the contractors accordingly.
