Home Weatherization – A Powersmith Energy-Saving Service

Sealing your home’s “envelope” can greatly reduce energy loss in your home.

Even when your windows are all shut tight, the equivalent of more than one open window’s worth of air is likely escaping outside.

That’s because indoor air can find many ways to flow out (or in) through gaps, cracks and holes in your basement, main floors and attic. Many of these escape routes are literally built into your home by contactors and plumbers who drill, saw and hammer openings while placing studs, joists, rafters, beams, wires, air ducts, electrical outlets, water lines and waste pipes throughout your house.

These openings cause your air conditioner or heater to operate far more than otherwise necessary, which costs you tremendous amounts of money each year in equipment wear and utility energy costs.

We scientifically locate these leaks through infrared thermal imaging and blower door testing. After talking with you and providing a firm estimate, we then begin sealing common air-leak areas such as:

  • Pipes and wires
  • Chimney
  • Frames and drywall
  • Rim joist and sill plates
  • Sump pump
  • Windows
  • Doors
  • Sinks
  • Fans
  • …and more!

Also read how we seal air ducts throughout your home as part of this weatherization service. And learn about the importance of a thorough duct cleaning as well.

Please note that Powersmith believes strongly in Property Performance Improvement (PPI) and so ONLY provides weatherization services as part of a complete home energy audit package. Our goal is to provide you with a more comfortable, healthier home while significantly decreasing your energy bills. A full-service energy audit/retrofit is the only way we can achieve this goal.

The walls are fully insulated, the ceiling is fully insulated. They just did a really good job!

We no longer walk on cold floors — it's such a pleasure to know that the house is insulated now and so quiet... They were prompt and made sure I was a happy customer before they left the home. They left it spotless!
