Insulation

We do all types of insulation:

  • Blown-in cotton, fiberglass and cellulose
  • Fiberglass batts
  • Spray foam, closed and open cell

Foam insulation makes a great air seal and has a high ‘R-value.’ (R is for ‘resistance’ to heat transfer.) So it prevents heat loss (or summer heat gain) from air movement (convection) as well as conduction from one surface to another. We use both open cell and closed cell foam insulation made from polyurethane. It contains no formaldehyde, cures fast and lasts a long time. It won’t sag or fall down as fiberglass batts often do over time.

We also offer dense pack cellulose, as well as loose fill fiberglass and loose fill cellulose.

No sub-contracting: We have our own blower rigs and do all of the work with our own crews, rather than sub-contracting, so our prices are very competitive.

Call us for a quote! Right now, PG&E is offering big rebates if you insulate. In many cases the rebate covers over 60% of the job cost!

Most older Bay Area homes were constructed with no insulation. Even homes that have been remodeled may still have little or no insulation. This makes them drafty and expensive to heat. The good news is that adding insulation is cheap and pays big dividends.


A typical attic in an Oakland bungalow. This house had a kitchen remodel by a ‘paint the pig’ house flipper who did nothing to insulate it.


Blowing cellulose insulation into an attic.


Often insulation is poorly installed. It is supposed to be in continuous contact with the surface it is insulating, without sagging, bulges, gaps, or compression. This crawlspace insulation is supposed to be up against the floor, not hanging down on the ground.

Insulating walls in older homes is simple and easy, and makes a huge impact on comfort and energy use. We drill small holes into each stud cavity, then blow in cellulose insulation. Its just ground up newspapers treated with non-toxic fire retardant. Then we patch the holes and away we go. It takes about one day to do a 2 or 3 bedroom house.


If you have a stucco house, we drill holes from outside to blow the insulation into the walls. These holes have already been patched and are ready to re-paint. If your house has wood siding, then we make the holes on the inside. Moving around your furniture adds a little time and is slightly disrupting, but does not cost more.


The holes are only about 1.5 inches wide. Can you see the insulation in there?


We do foam. It works great in drafty houses.


We often use infrared thermography to help us find problems. Can you tell where the insulation is missing (from a previous installation) in the ceiling and the wall?


Sometimes people have really good intentions, but they are not clear on the concepts.
Somebody went to a lot of effort to insulate the exterior wall of this vented attic. Because it is vented, the attic is basically outdoor space. The insulation should be on the attic floor, where the ‘thermal boundary’ is located. We are well trained on the concepts.
