Attic Insulation
Why Attic Insulation Matters
Comfort Year-Round
Attic insulation is one of the highest impact upgrades you can make for home comfort. By reducing heat transfer between your living space and the roof deck, insulation keeps indoor temperatures steadier through summer heat and winter cold. Rooms feel more consistent from floor to floor, and your HVAC system does not need to work as hard to maintain your thermostat set point.
Lower Energy Bills
When an attic is under-insulated or leaky, conditioned air escapes and outdoor air infiltrates. The result is longer HVAC runtimes and higher utility costs. Properly sized and installed insulation helps your system reach temperature faster and stay there more efficiently. Many homeowners see a meaningful reduction in seasonal heating and cooling expenses after bringing attic insulation up to recommended levels.
Protecting Your Home
Insulation works together with air sealing to control moisture and prevent condensation. That protects framing, roof sheathing, and drywall from damage. A well-insulated, well-sealed attic also helps reduce the risk of mold growth, improves indoor air quality, and can extend the service life of your HVAC equipment by reducing strain.
Frequently Asked Questions
1. How much insulation do I need in the attic?
Recommended attic levels vary by climate and roof design. During your assessment we measure existing depth, review local guidelines, and propose an R-value that balances comfort, efficiency, and cost for your home.
2. Do I need air sealing if I am adding insulation?
Yes. Air sealing and insulation work together. Sealing gaps and penetrations before adding new material reduces drafts and moisture movement, which improves comfort and protects the building envelope.
3. Will new insulation lower my energy bills?
Most homeowners see a meaningful reduction in heating and cooling costs after upgrading attic insulation and completing basic air sealing. Actual savings depend on your home’s size, existing conditions, and usage patterns.
Which insulation type is best for my attic?
It depends on attic access, existing materials, ventilation, budget, and goals. We install blown-in fiberglass, spray foam, and batts, and we will recommend the option that delivers the best performance for your space.
Blown-In Fiberglass
Ideal for most attics with open joist bays. Blown-in fibers fill voids and cover irregular areas for even, continuous coverage. It is non-settling, non-corrosive, and delivers strong thermal performance.
Spray Foam
Provides insulation and air sealing in one application. Closed-cell foam adds rigidity and moisture resistance, while open-cell foam offers excellent air control. Foam can be a strong choice for complex rooflines or when a semi-conditioned attic is desired.
Batt Insulation
Pre-cut fiberglass or mineral wool batts are a dependable option in attics with uniform spacing and accessible bays. Batts are often paired with targeted air sealing for reliable results.

Our Attic Insulation Process
1. Home Energy Assessment
Every project begins with a thorough assessment. We measure existing insulation depth and condition, inspect ventilation, identify air leaks around gaps and penetrations, and check for moisture concerns. This evaluation allows us to recommend the right materials and R-value for your home.
2. Preparation and Air Sealing
Performance starts with the basics. Before new insulation goes in, we prepare the space by protecting work areas, sealing accessible leaks at top plates, wire penetrations, plumbing stacks, and around recessed lights rated for coverage. Air sealing limits uncontrolled airflow, which is essential for comfort and efficiency.
3. Professional Installation
Based on your goals, budget, and attic design, we install the insulation type that fits best. Coverage, depth, and uniformity are verified during installation to ensure the material performs to its rated R-value.
4. Final Inspection and Clean-Up
We confirm coverage, depth, and clearances around heat-producing fixtures as required. Baffles and ventilation pathways are checked, the workspace is cleaned, and you receive a summary of the upgrades along with care recommendations.
Signs You May Need New Attic Insulation
- Uneven temperatures between rooms or floors
- Frequent HVAC cycling or long runtimes to reach set point
- Drafts, cold ceilings in winter, or hot ceilings in summer
- Visible gaps, low insulation levels, or darkened insulation from air movement
- High energy bills compared to similar homes
- Musty odors or past moisture issues in the attic
