The area must be thoroughly cleaned before caulking any joint, gap or crack. Surfaces to be caulked must be dry and free of all dirt, dust, oil, mildew, loose paint, and old caulk. Only apply when caulk, surface and air temperatures will remain above 40°F. Do not apply on surfaces that are above 120°F. Do not apply on exterior surfaces when rain is immediately expected.

Frequently Asked Questions:
Why is caulking or Home Sealing important?
Reducing air leaks by caulking or sealing is recommended by the EPA ENERGY STAR® program to increase the energy efficiency of your home by improving the envelope. Sealing air leaks allows full performance of your insulation and can cut up to 20% of your energy bill according to the EPA.
Visit www.energystar.gov/index.cfm?c=home_sealing.hm_improvement_sealing for more information.
What is a home envelope?
The exterior of your home is also called the “envelope” or shell. The insulation, outer walls, ceiling, doors, windows, and floors all work together to control airflow in and out of the structure, repel moisture, and prevent heat from being lost or gained inside your home. A high-performance envelope helps maintain a consistent temperature even under extremely hot or cold conditions. The goal of Home Sealing is to improve the home envelope, to make homes more comfortable and energy efficient.
Is Home Sealing something I can do myself?
Absolutely! You can seal up holes, weather-strip doors, caulk around gaps in pipes and wire, floors, basements, and crawl spaces. Remember, it’s important to air-seal before adding insulation. ENERGY STAR® has a written do-it-yourself guide to help with the process of home sealing, which can be downloaded by going to http://www.energystar.gov/ia/partners/publications/pubdocs/Seal_and_Insulate.pdf
