Gaps and cracks around windows, door frames, electrical outlets or plumbing fixtures may seem small, but if you've got enough of them, they can add up. Exterior gaps waste energy and decrease the comfort level in your home. Sealing gaps and cracks from air leaks costs a little, but can save a lot of time and money.

TOP REASONS WHY HOME SEALING IS IMPORTANT

1.Reduce Energy Costs – According to the EPA, air leakage accounts for 25 to 40 percent of the energy used for heating and cooling a typical home, resulting in higher energy costs in both summer and winter.  Air leaking through gaps and cracks in a home can add up to as much airflow as an open window. Proper sealing can save the average homeowner 15 – 20% of total energy costs per year. If the average family spends $2,500 per year on energy bills their costs could be reduced by $500. 

2. Prevent Water Damage – Water seeping through small cracks and gaps can lead to costly damage, such as rotted wood and structural deterioration.  To control water damage, seal around all doors and windows, as well as cracks around joints and the foundation.  A silicone sealant provides the best protection against water.

3. Maximize Insulation – The biggest air leaks are often found in the attic and basement.  When insulating these areas, make sure all air leaks are properly sealed to ensure you receive the maximum value of the insulation.

4. Prevent Unwanted Mold – Improperly sealed sinks, faucets, bathtubs and other water sources can be a breeding ground for mold growth, causing an unpleasant appearance well as health risks and odors.  If not properly treated, mold growth can spread throughout your home and even weaken the home’s infrastructure in extreme cases.

5. Avoid Allergens – Proper sealing means there are fewer holes for pollen, dust and pollution to infiltrate the house, reducing your risk of allergies.

6. Breathe Easy – Proper sealing helps keep indoor air clean.  Mild to moderate levels of household mold can exacerbate asthma or cause flu-like symptoms and skin rashes.

7. Avoid Bugs in the Home – Water bugs, mites, ants and other pests can find their way into your home through small holes, especially in water environments.

8. Keeping Your Home Quiet – Proper sealing helps reduce outside noise, making your home quiet and cozy.

9. Maintain Proper Humidity Levels – Air leaks in the home allow warm humid air to escape, drawing in drier air and changing the humidity levels in the home.  Maintaining proper humidity levels protects your furniture and home from drying out.

10.Sealing Is Easier than Ever – Protecting your home and saving money can be simple by being prepared and sealing your home.  The best protection against air leaks, lost energy and water damage is a high-performance silicone sealant such as GE’s Silicone II family of products.  The best seal against water and the elements, silicone doesn’t shrink or crack, and moves as the home expands and contracts with changing temperatures, making it the most flexible and durable product available. Try GE Silicone II Window and Door or XST, a paintable formula that combines the superior performance of a silicone and the paintability of an acrylic.
