Are you wanting to re-caulk your home?

Re-caulking of a home is a crucial part to energy savings and building preservation. When the caulking on your home has failed, the exterior air will enter the cracks and the interior air will escape through these cracks as well. By making sure all of these areas are properly sealed, you are taking a major step into energy conservation.
As much as 20-30% of your cooling and heating costs are wasted to air leaks. In some cases, this percentage is much higher.
Sealing all the exterior windows, doors, vents and any other crack or crevice will help reduce costs on your utility bills.
