Attic Insulation in Coronado, California

The marine moisture and the mild coastal winters make the attic insulation the key to the home comfort. The moisture-resistant insulation keeps the damp out and the temperature steady. Attic insulation in Coronado means the barrier that protects the home.

Signs Your Coronado Home Needs Better Attic Insulation

• The upstairs rooms are colder than the downstairs — the heat is escaping through the ceiling
• The energy bills are high — the heat is escaping
• The attic has insulation that is level with the joists — the depth is not enough
• The house is drafty — the air escapes through the ceiling
• The attic is damp — the moisture is getting through the ceiling

Why Coronado Homes Need Good Attic Insulation

The marine moisture is the main reason. The damp air gets into the attic, and the insulation keeps the moisture from the living space. The moisture-resistant insulation is the right choice.

The mild winters add a second reason. The coastal winters are mild, but the heat still escapes through the ceiling. The insulation keeps the heat in and the energy bills down.

How We Insulate Attics in Coronado

1. Inspect the attic — check the current insulation, the depth, and the moisture
2. Air-seal the gaps — seal the openings around the pipes, the vents, and the wiring
3. Blow in the insulation — the moisture-resistant cellulose or fiberglass
4. Check the depth — 12 to 18 inches for the recommended R-value
5. Install the baffles — keep the soffit vents clear for the airflow
