We had a condo built last Feb/02. We have had problems with air coming in where the wall meets the floor. At one point the contractor said he realized the house was underinsulated, so they told us to wait until this summer, and with much proding on what they were going to do, they came and blew some insulation in the attic. When winter came, we still had the air problem, so they came back and put a bead of silicon between the wall and the floor and the west and east side. Those areas are still cold and the wall is cold in those areas. This month, air was coming from the cupboards in the kitchen on the east side, they pulled out the cupboard and my husband said that the air was rushing out. They put a bead of silicon between the wall and the floor and used foam insulation around the plumbing, but the area is still cold. Also, yesterday I noticed air coming in between the wall and the floor on a inner wall. We have cathedral ceiling in the living room, (east wall) and 8 ft ceilings in the bedrooms, (west wall). Is this just a band aid fix? What can we do. Also, we have had problems from the start with our fireplace, they were suppose to build it for vented gas logs, and they used a heatilator unit for wood burning and we get a draft coming from the bottom of the unit. It is so bad we had to tape it. Please help us!
