Home Insulation: Your Comprehensive FAQ

What types of home insulation do you offer?

We install fiberglass batt, blown-in cellulose, spray foam, and rigid foam board insulation. The best type depends on the location in the home, existing insulation, and your energy efficiency goals.

How do I know if my home needs new insulation?

Signs include uneven indoor temperatures, high energy bills, cold drafts, or insulation that's visibly compacted or deteriorating. A home energy assessment can help determine if upgrades are needed.

What parts of the home benefit most from insulation?

Attics, walls, crawl spaces, and basements typically provide the most energy savings when properly insulated. Sealing gaps around windows, doors, and ductwork is also important.

How long does the insulation installation process take?

Most single-family home insulation projects are completed in one to two days. The timeline depends on the size of the space and the type of insulation being installed.

Is spray foam better than fiberglass?

Spray foam offers higher thermal resistance (R-value) and air sealing in one application, making it more effective in many situations. Fiberglass is more affordable and works well in accessible areas when installed properly.

What is R-value and why does it matter?

R-value measures an insulation material's resistance to heat flow. Higher R-values indicate better insulating performance. Choosing the right R-value depends on your climate and the area being insulated.

Can insulation help reduce noise?

Yes, insulation can reduce sound transmission between rooms and from outside. Dense materials like cellulose and mineral wool are particularly effective for sound control.

Do I need to remove old insulation before installing new?

In some cases, yes—especially if the old material is wet, moldy, or infested. Otherwise, new insulation can often be added on top of existing layers to improve performance.

How much does home insulation cost?

Costs vary based on the size of your home, insulation type, and installation complexity. On average, homeowners spend between $1.00 to $3.50 per square foot. We provide estimates after a home evaluation.

Will new insulation lower my energy bills?

Yes, proper insulation helps maintain consistent indoor temperatures and reduces heating and cooling demands. This often leads to noticeable savings on utility bills.

Is insulation installation messy or disruptive?

We use clean installation methods and protective coverings to minimize disruption. Most work can be done without major changes to your home or daily routine.

Are your insulation materials safe for indoor air quality?

Yes. We use products that meet industry safety standards and have low or no VOCs (volatile organic compounds), ensuring healthy indoor air quality.

Do you offer attic air sealing services?

Yes, attic air sealing is often done alongside insulation to close gaps, cracks, and penetrations that allow conditioned air to escape. This step improves energy efficiency.

How long does insulation last?

Most insulation materials last 20–30 years or longer if they remain dry and undisturbed. Some types, like spray foam, can last the lifetime of the home.

Can insulation be installed in older homes?

Yes, we frequently work with older homes. Installation methods vary depending on access to wall cavities, attic spaces, and whether original materials need to be removed.

Do you offer insulation for new construction?

Yes, we provide insulation for both new construction and remodeling projects. We work with homeowners, builders, and contractors to meet building code requirements and performance goals.

Do you handle moisture or ventilation issues before insulating?

Yes, we assess and address moisture or ventilation concerns before insulation is added. Proper airflow is important to prevent mold, mildew, and insulation degradation.
