Insulation Installation in Ben Lomond, CA
101 Exterminators handles insulation installation in Ben Lomond — blown-in attic insulation to Title 24 R-values and supported batts in crawl-space joist bays. Many houses here started as summer cabins and were never insulated for a long, wet mountain winter under a canopy that keeps the sun off. On a termite-active parcel, borate-treated cellulose is worth asking about. CA licensed and insured, in the San Lorenzo Valley since 2005.

Attic insulation below R-19 or compressed to less than 4 inches — significant energy loss

How It Works
Our Insulation Install Process in Ben Lomond
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Ben Lomond.
Existing Conditions Assessment
We measure current insulation depth, note any areas requiring air sealing before installation, and confirm that the attic is rodent-free before new insulation goes in.
Air Sealing (As Needed)
Gaps around recessed lights, plumbing penetrations, HVAC ductwork, and top plates are sealed before insulation is blown in to maximize thermal performance.
Insulation Installation
Machine-blown cellulose or fiberglass is distributed to uniform depth and density across the attic floor or specified area. Depth gauges are placed and photographed for documentation.
R-Value Confirmation
Installed depth is documented and final R-value confirmed. For permit applications, we provide the necessary documentation of materials and installation specs.

Common Questions
Insulation Installation FAQs for Ben Lomond
How much insulation should a Ben Lomond attic actually have?
Title 24 attic targets for this climate zone generally land in the R-38 to R-60 range, which is well above what most San Lorenzo Valley cabins carry. If you can see the tops of the ceiling joists when you look in, you are short. We measure existing depth, identify the material, and tell you what has to be added to reach the target instead of guessing from the hatch opening.
Is borate-treated cellulose worth choosing in a mountain house?
On a Ben Lomond parcel it usually is. Borate-treated cellulose puts insect resistance into the same material doing the insulating, which matters where subterranean and dampwood termites are active and the canopy keeps delivering rodents to the roof. It is not a termite treatment and does not substitute for one. It is a sensible default in a valley where wood pests are the normal condition rather than the exception.
Should I insulate the crawl space floor or cover the ground under my cabin?
Both, and the order matters — vapor barrier on the soil first, insulation in the joist bays second. Putting batts up over bare wet dirt in a Ben Lomond crawl space just gives rising moisture something absorbent to move into, and those batts sag and fall within a few years. Cover the ground, confirm the sub-area is venting, then insulate the floor above with the batts mechanically supported rather than stapled and hoped for.
