In our seemingly never-ending quest to track down reasons why we have such a huge gas bill, we found 2 wall sections and an exterior floor section that were never insulated. We suspect another floor section, too. There were sections that we knew were missing some insulation in the past, but Van Metre assured us that they were fixed before drywall was put up (or else it wouldn't have passed the county inspection). I've learned not to trust anything they tell me, so I used an infrared thermometer and scanned the wall along the suspicous areas and noticed a 5 degree (F) drop in between the studs. I did this for both sections, and when the drywall was cut out, there was nothing but a hole. I used the IR thermometer to detect a drop in the carpet temperature, too. I had to drill down under the floor board to find that there was nothing there, either. We have a Dogwood; this was in the master bedroom overhang at the balcony. We suspect the insulation company didn't bother to insulate the jacuzzi bump-out, either. They're in the process of fixing the wall areas, but I've lost a lot of vacation time to be home when work is being done. And I'm going to lose a lot more for them to finish up the work (twice the insulation folks never showed up). I know a house near us had similar problems with missing insulation. It's important to make sure your house was done right or else you'll have a huge gas bill like ours ($189 for October 1-31!). Has anyone else had similar problems?
