Attic Insulation in Granite Bay, California

The attic is where the house loses the most energy. The heat rises in the summer and the warmth escapes in the winter, and the insulation is the barrier that stops it. Attic insulation in Granite Bay means the layer that keeps the house comfortable and the bills lower.

Signs Your Granite Bay Home Needs Better Insulation

• Hot rooms on the top floor — the air is leaking through the ceiling
• High cooling and heating bills — the energy is escaping through the attic
• Uneven temperatures between the rooms — the insulation is not consistent
• Condensation in the attic — the warm air is meeting the cold deck
• The attic insulation is old or thin — the original insulation has settled

How We Insulate Attics in Granite Bay

1. Inspect the attic — check the current insulation, the air leaks, and the vents
2. Seal the air leaks — caulk the gaps around the pipes and the wires
3. Install the baffles — keep the soffit vents clear of the new insulation
4. Blow in the insulation — the fiberglass or the cellulose, to the target R-value
5. Verify the coverage — check the depth and the evenness
