The challenge
An attic that needed clearing and sealing
The crew found a San Mateo attic carrying old material and open penetrations around fixtures, piping and vents.
The service
What the crew did, in order
Prep and containment
Protective floor and dust barriers set through the work path before anything was opened, so the work stayed inside the attic and out of the rest of the home.
Remove the old insulation
The existing insulation layer taken out with a heavy-duty vacuum across 1,040 sq ft, leaving bare joists and a clear view of the deck.
Clean and sanitize
Rodent waste, droppings and nesting material vacuumed out, then the surfaces treated with OdoBan sanitation to clear odor, bacteria and the scent trails that draw rodents back.
Seal and rodent-proof
Entry points sealed with wire mesh, polyurethane foam and cement. Gaps around fixtures, piping, wiring and vents air-sealed in the same pass — the openings that leak conditioned air are usually the ones rodents use.
New insulation
New insulation installed across 1,040 sq ft, bringing the attic to current California code on a clean, sealed deck rather than on top of the old layer.
The result
1,040 sq ft brought up to standard
The attic is back to current standard.

Questions homeowners ask
Attic work in San Mateo, answered
Should this attic have had insulation added instead of replaced?
Where a layer is clean and still at its rated R-value, adding over it is the cheaper and correct call. Replacement is for layers that have settled, been contaminated, or fallen below code. Here is how to tell which you have: cleaning versus full replacement.
What does rodent proofing include in San Mateo?
Rodent proofing is exclusion work: sealing the gaps and openings rodents use to get in, with wire mesh, polyurethane foam and cement. Live removal, where it is needed, is handled by a licensed pest control provider. Atticare USA has written up how Atticare USA seals entry points and the 5-step restoration process that follows. Worth reading before you compare quotes: how to compare rodent-proofing warranties.
