Why Seal and Insulate?

The sale of homes is booming on the Austin - San Antonio corridor... how is you newly purchased home insulated? Call Sunshine - we do most work on one day in a professional way. 

Insulation properly selected and professionally installed will return more of its investment than any other building component. Insulation pays dividends throughout the life of the structure, returning your investment in a variety of ways, including appearance, comfort, fuel savings, condensation prevention and noise control.

Save Energy and Money.

Air that leaks through your home’s envelope − the outer walls, windows, doors, and other openings − wastes a lot of energy and increases your utility costs. A well-sealed envelope, coupled with the right amount of insulation, can make a real difference on your utility bills. EPA estimates that homeowners can save an average of 15% on heating and cooling costs (or an average of 11% on total energy costs) by air sealing their homes and adding insulation in attics, floors over crawl spaces and basements.

Increase Comfort.

Insulation helps keep your home warm in the winter and cool in the summer. When correctly installed, insulation can deliver comfort and savings, especially during the hottest and coldest times of the year. Sealing leaks and adding insulation can improve the overall comfort of your home and help to fix many of these common problems:

  • Reduced noise from outside
  • Less pollen, dust, and insects (or pests) entering your home
  • Better humidity control
  • Lower chance for ice dams on the roof/eves in snowy climates

In fact, if you added up all the leaks, holes, and gaps in a typical home’s envelope, it would be the equivalent of having a window open every day of the year!

Most Homes Will Benefit.

Prevents Consendation

Most homes in the United States do not have enough insulation and have significant air leaks. Did you know that 9 out of 10 homes in the U.S. are under-insulated? Sealing air leaks around your home and adding insulation are two of the most cost-effective ways to improve energy efficiency and comfort in your home. By tackling both projects, you can maximize your comfort and save up to 10% on your annual energy bills.
