It's no secret that drafts are uncomfortable. Less obvious is the fact that they're also costly, because they introduce inefficiency to home HVAC systems. By sealing around your doors and windows, you can de-draft your home, at once ensuring both a warmer environment and lower monthly energy bills. Caulking might do the trick, but if you have a stucco exterior with cracking or crumbling in sensitive areas, go a step further—replace the old stucco with durable, high-strength Rapid Set Stucco Mix. Engineered to minimize shrinkage, it defends against many of the failures that cause drafts in the first place.
