Attic Insulation in Pacifica, California

The Pacifica coastal climate is mild, but the sun still heats the attic in the summer and the winter nights still leak the heat. Many of the older beach homes are under-insulated. Attic insulation in Pacifica keeps the home comfortable and the energy bills low.

Signs Your Pacifica Attic Needs Insulation

• The rooms upstairs are too warm in the summer — the heat is coming through the ceiling
• The energy bill is high year-round — the heat is leaking through the roof
• The insulation is below the level of the floor joists — the attic is under-insulated
• The house feels drafty in the winter — the air is leaking through the attic
• The attic is damp or musty — the insulation is not working with the ventilation

Why Pacifica Homes Need Attic Insulation

Many of the older beach homes in Pacifica were built before the modern energy codes. The attic insulation was never upgraded, and the heat leaks through the roof in the summer and the winter.

The insulation slows the heat transfer. In the summer, it keeps the attic heat out of the living space. In the winter, it keeps the house heat in.

How We Insulate Attics in Pacifica

1. Inspect the attic — check the insulation, the air leaks, and the ventilation
2. Seal the air leaks — caulk and foam the gaps around the pipes, the wires, and the fixtures
3. Install the insulation — blown-in cellulose or fiberglass, or spray foam
4. Check the ventilation — the insulation and the ventilation work together
5. Verify the depth — the insulation meets the recommended level
