Stop Losing Heat Through Your Ceiling

Heat rises, and without proper insulation your home can lose a significant amount of energy through the ceiling

When to Insulate Your Ceiling

Choose ceiling insulation when your home has uneven temperatures, rising energy bills, or little insulation

Your Upstairs is Always Hot or Cold

If your second floor is always hotter in the summer and colder in the winter, your attic insulation isn’t doing its job—and your HVAC is probably paying the price.

Energy Bills Keep Climbing

When a home loses heat through the ceiling, heating and cooling systems must run longer to maintain indoor temperatures, often leading to higher monthly energy costs.

Your Home Has Little Insulation

Many older homes were built with minimal ceiling insulation, making it easier for conditioned air to escape and outdoor temperatures to affect indoor comfort.

Ice Dams Form in Winter

In colder climates, heat escaping through poorly insulated ceilings can melt roof snow, which then refreezes at the edges and creates damaging ice dams.

Frequently Asked Questions?

How do I know if my ceiling insulation needs to be replaced or upgraded?

Determine if ceiling insulation needs replacement or upgrading by checking for uneven temperatures, hot summers, cold winters, and rising energy bills. Inspect insulation levels for gaps, compression, or age-related degradation. Upgrade or add insulation if it falls below current recommendations, improves comfort, and reduces energy use. Professional inspection ensures accurate assessment.

Can new insulation be added over existing ceiling insulation?

Add new ceiling insulation over existing insulation if the current material is dry, mold-free, and structurally sound. This increases R-value and improves thermal performance without full removal. Remove existing insulation first only if it is damaged, contaminated, or severely compressed. Conduct an inspection to prevent moisture or airflow problems.

How long does ceiling insulation installation take?

Complete ceiling insulation installation within a single day for most homes, especially when adding insulation from the attic. Larger homes or projects requiring removal, air sealing, or prep work may take longer. Contractors evaluate the space first to provide an accurate timeline before starting the work.

What type of insulation works best for ceilings?

Use cellulose, fiberglass, or spray foam for ceiling insulation. Blown-in cellulose and fiberglass cover large attic areas evenly and provide strong thermal resistance. Spray foam works best for air sealing or filling irregular cavities. Choose insulation based on attic design, roof structure, and goals for energy efficiency and comfort.

Will ceiling insulation lower my energy bills?

Lower energy bills by installing ceiling insulation, which reduces heat loss in winter and heat gain in summer. Proper insulation slows heat transfer from ceilings and attics, allowing heating and cooling systems to operate more efficiently. Savings vary with home size and existing insulation, but many homeowners see reduced energy usage after upgrading ceiling insulation.

Does ceiling insulation improve comfort throughout the home?

Improve home comfort by installing ceiling insulation, which stabilizes indoor temperatures. Proper insulation prevents warm winter air from escaping and reduces summer heat from radiating downward. This minimizes hot and cold spots, especially on upper floors, allowing homes to maintain consistent temperatures and enhancing overall comfort year-round.

Do I need air sealing before installing ceiling insulation?

Perform air sealing before installing ceiling insulation to block gaps around lighting, wiring, plumbing, and attic access. Sealing these leaks prevents conditioned air from escaping and ensures insulation effectively slows heat transfer. Addressing air leaks first maximizes insulation efficiency and improves overall home energy performance.

Will installing ceiling insulation disrupt my home?

Minimize home disruption by installing ceiling insulation from the attic. Most projects do not require opening walls or ceilings inside the home. Professional installers use equipment to distribute insulation evenly, allowing homeowners to remain in the house while work is completed quickly, depending on space size and condition.

Nealon did an outstanding job in terms of courteous services, as their team members, as well as Chris who was responsible for directing the job, were most professional!!! They cleaned up nicely, and my goods remained intact. Also and happily stated, it’s been one week since they’ve installed insulation in our home, and we notice a huge difference in the amount of energy we are using for heating…which equates to $avings!!! In short, we’d use them again, and glad we chose them for this endeavor!!!

Dia CJW

Highly recommended. Their estimate was competitive, the work was done in a timely and clean manner, they explained what was done, and our house is warmer as we head into the winter. When we had a question, they came back out to talk with us and helped us answer our questions. I will use them again and recommend them to anyone.

They are an amazing company to do work with! Jen in the office is polite, pleasant, and very competent. The work was done well and very quickly. We had our attic and basement insulated. I would 100% recommend!

Timothy Saunders

The Nealon team was professional and considerate of my property. I noticed a 200-kilo watt decrease in my electric bill along with an additional savings in oil consumption of 50 gallons. No more drafty cellars and so far, the mice have gone elsewhere.

Christine

Fast, efficient and great price! Didn’t even notice them insulating our attic and making a big difference already! Would highly recommend for anyone that wants to cut down on their energy bill!!
