Insulation Removal

Insulation Overview


Does your home always seem to be cold during the winter or hot during the summer? Does it seem like the temperature in your home is never quite right? Are your heating and cooling costs driving up your utility bill? The culprit may be a matter of poor insulation in your attic or walls.

Home insulation is an important factor in keeping utility costs down, lowering your energy usage, and making your home more comfortable. A well-insulated home can help prevent outside temperatures from working against your heating and cooling system by reducing the amount of heat flow between the inside and outside of the home. This means your heater runs less in the winter, and your air conditioner runs less in the summer.

On average, you can save up to 20% on your home’s heating and cooling costs or up to 10% on its total energy costs by properly insulating your home and reducing unwanted air leaks all around your house*. Synergy Companies can help identify air leaks by performing a home energy audit. For optimal energy efficiency, your home should be properly insulated from the roof down to its foundation.

Synergy Companies has been performing insulation work in California for over 30 years, including attic, wall, floor, and duct insulation. We also install sound barriers and perform insulation removal as needed. Our experienced technicians can walk you through the various insulation options and provide you recommendations to meet your specific needs based on your home.

Types of Insulation


Home insulation comes in a variety of forms and materials, depending on where it’s being used in the house. Batts and blankets are pre-formed pieces of insulation that can work well when fitted between joists or around heating and cooling ducts, and can be made of fiberglass, cellulose, or denim. Loose-fill insulation is unformed, “loose” insulation that is blown in and can be used to insulate attics and walls, including existing walls where no insulation currently exists. Loose-fill is typically made of cellulose or fiberglass.

Cellulose is organic material made from plant fiber, oftentimes coming from recycled materials such as newspapers, and is treated with a natural fire retardant. Fiberglass is lighter and subsequently useful in areas where the weight of the insulation material must be taken into account.

When adding insulation, you do not have to use the same type of insulation that currently exists. You can add loose fill on top of batts or blankets, and vice-versa. With over 30 years of experience, our California energy specialists can help you determine the best insulation for your needs.

Attic Insulation

When considering insulation, the attic is generally the first place to start, as most of your heat will rise and go through your ceiling to the attic if there is inadequate or ineffective insulation. It is also often one of the easier places to access.

Wall Insulation

After attic insulation, wall insulation is the next most popular and effective place to put insulation when it comes to increasing the energy efficiency of your home. While there are many types of insulation available for walls, existing homes with finished walls require certain types of insulation that do not involve removing the interior drywall or the exterior siding.

Floor Insulation

Insulating the floor over a crawl space requires taking into consideration moisture control (both over the ground and as to the insulation) and whether you have a vented or unvented crawl space. (Unvented crawl spaces may require insulation of the perimeter instead.)

Insulation Removal

Old insulation does not need to be removed just be virtue of its age. Instead, if a home is poorly insulated, more insulation can be added on top of the existing layer to bring it up to current standards and increase your homes efficiency and comfort. However, when insulation has become damaged or infested with rodents, it is time to seriously consider having your old insulation removed and replaced with a fresh layer.
