Home Interior HVAC - Frame to Foundation Gaps

[goodysgotacuda]

I think I know the answer to this one, but I will give it a shot.

Our home has several very cold areas in the Winter which are being driven from underneath the baseboards. The carpet against the wall is very cold and I suspect the house frame is not properly sealed to the foundation.

Without tearing everything up, is there anything that I can apply in homes to slow down the air leak?

If not, I assume either the baseboards need to come up, or the siding off of the house to properly address this?

Our house on the MS Gulfcoast has the same issue, a few things we used;

• clear silicone caulk if you can get to the gap
• those spray cans of foam sealant
• round foam weather strip sold at hardware stores, jam up under your sheathing/siding on the outside wall to fill the void so air cant get into those gaps

Good Luck!

LOL! I have the same problem! Most of you know I live in a barn that was converted in the mid 70's. I opened the border wall a couple of weeks ago while changing doors and found a poorly insulated concrete knee wall where the breeze blows in between the wood and the concrete.
My Spring/Summer plan is to remove the lower exterior sheeting and use spray foam to seal the gaps. I am toying with removing the interior border wall to have it spray foam sealed which would cover the concrete knee wall better also. Though I am partial to believing this may also open a realm of more poorly done work that I would rather not know about!
