Why Old Houses Had Vents Under the Floor (And Blocking Them Is Wrong)

That small grille low on the outside wall of an old house is there for a reason, and it is the one people most often stuff with rags, bury under a flowerbed or paint shut when the weather turns cold. Rose explains what the vents under an old wooden floor actually do, the ordinary household habits that block them, and the simple walk around the house that catches the problem before soft floor joists turn into an expensive repair. She also covers how to fix a cold, drafty floor the right way, and why a professionally sealed crawlspace is not the same thing as a blocked vent. #OldHouse #FoundationVents #WoodRot
