Most homeowners are spending 10-20% more on their utility bills than they have to!

Insulation keeps you comfortable in your home by shielding you from outside elements like heat, cold, and noise. Insulation limits heat movement and improves your home’s ability to maintain indoor temperature.

Increasing your home’s energy efficiency will save you money on your monthly utility bills. With less heat passing through your well insulated walls, floors and ceilings, your heating and cooling units will run less, and last longer. Energy efficient homes may command higher sales prices, according to a study by researchers at UC Berkeley and UCLA.

Most homes are not sufficiently insulated to minimize energy use. And there may be other problems causing you to spend more than you have to on your utilities.

We take the guesswork out of making your home energy efficient with our whole home evaluation. We check for areas of heat transfer that will save you significantly on your heating and cooling costs. We make recommendations on insulation, air leaks, HVAC equipment, windows and you’re your home’s ductwork.



attic insulation by The Greenhart Company

Heat rises, so one of the first places to check for adequate insulation is your attic. This is a good place to use a professional as there are many hazards involved with putting in attic insulation. It’s a cramped work area, with lots of dust, and there is the potential risk of falling through the ceiling.

Our home energy audit will check your attic insulation, the condition of your ductwork, and check for air leaks.


wall insulation by The Greenhart Company

Some homes may have no wall insulation, others may have insulation that was “blown” into the space between the inner and outer walls. Over time, the loose insulation material may can settle, leaving gaps where heat can pass through, costing you both money and comfort.

A side benefit of optimal wall insulation is that it also blocks outside noise, making your home quieter inside.


floor insulation by The Greenhart Company

Having sufficient floor insulation can really add to your comfort. Cold air under your home draws heat from your floor, and the cold floor draws heat out of your home. Since you are closer to the floor, you feel the cold more.

While we are adding insulation to your floor, we will also seal air leaks that are letting heat pass. You will really notice a dramatic difference in your comfort level, with suitable floor insulation and air leak sealing.


There are several types of insulation. The more commonly used insulation is either cellulose or fiberglass. We typically use cellulose insulation that is made from paper. It is composed of 80% recycled materials like old newspapers, bags, etc. Cellulose is our preferred insulation type because it’s safe for our customers and licensed installers.

We also use fiberglass insulation made from 45% recycled materials. Each bag of fiberglass insulation contains more than 34 recycled glass bottles. It’s free from dyes and chemicals. And it has a GREENGUARD Gold Certification (formerly known as Greenguard Children and Schools certification). It is verified to be 100% formaldehyde free.

After your home energy audit is complete, we will be able to advise of you of the best insulation material to use, in the areas where additional insulation is needed.


Air Sealing and insulation go hand-in-hand when it comes to maximizing your home’s comfort and energy efficiency. Air leak sealing keeps air from escaping through holes or cracks in your home. We give special attention to areas like windows, doors, air ducts, attics, walls, and floors. Sealing air leaks in your home will trim heating and cooling costs, plus reduce dust and other allergens thereby improving your indoor air quality.

Your Greenhart technician will use a “blower door” to test for air leaks in your home. You will be able see the location of the air leaks revealed. We use a variety of techniques to seal air leaks depending on their size and whether they are a component of your home that moves (like doors).
