I had Harvey windows (based in Massachusetts) installed professionally in my house about 5 years ago.
The contractor insulated on the sides of the windows, as he should have. But I get a terrible draft where the windows close. I have caulked all around the inside frame.
Both the contractor and manufacturer say the draft is caused by a lack of insulation underneath the sill. If that is the case - why didn't the contractor insulate that area? Is it that hard to get to? Also, can I drill a hole and and put expanding foam in that area? Someone told me if I did that, that it could warp the frame. Is that true?
There was cellulose blown into the walls many years ago, but that has settled.
I am not happy with these windows at all. Next time, I'll go with Andersons. All the contractors in the Boston area seem to like Harveys, but I think they stink.
Any info on how I can rectify this problem would be appreciated.
