Comfort Starts With Sealing
Control Air Leaks and Improve Year-Round Comfort
Small gaps around framing, rooflines, penetrations, and hard-to-reach areas can allow conditioned air to escape and outdoor air to enter. That unwanted air movement may contribute to rooms that feel too hot in summer, too cold in winter, or difficult to keep consistent.
Spray foam insulation expands after application, helping fill irregular spaces and create a continuous air-sealing layer where the selected assembly allows. When it is the right fit for the building, it can strengthen the thermal boundary, support indoor comfort, and reduce the workload caused by uncontrolled air leakage.
Property and Area Assessment
We inspect the intended installation area, review the existing conditions, and identify gaps or transitions that may be affecting performance.
A Project-Specific Recommendation
We explain whether spray foam is appropriate for the space and outline the scope based on the home, access, and insulation goals.
Careful Preparation
The work area is prepared to protect nearby surfaces and support a clean, controlled application.
Professional Installation
Spray foam is applied to the planned surfaces with attention to consistent coverage and the details that help form an effective air barrier.
Final Review
We review the completed work and make sure the project area is left ready for the next step.
What’s Included with Spray Foam Insulation
Air Sealing
Spray foam can help close small gaps and cracks that traditional insulation alone may not address.
More Consistent Temperatures
A stronger thermal and air boundary can make rooms easier to keep comfortable through Frederick’s changing seasons.
Energy-Efficiency Support
Reducing uncontrolled air movement may help the heating and cooling system maintain the set temperature with less wasted energy.
Moisture-Control Support
In an appropriate building assembly, the recommended spray foam system can help limit the movement of moisture-laden air through gaps.
Coverage in Irregular Spaces
The expanding material can conform around framing and other details that are difficult to cover with rigid, pre-sized products.
Long-Term Performance
Properly selected and installed spray foam is designed to remain in place as part of the building envelope.
When Should You Consider Spray Foam Insulation?
Spray foam may be worth considering when:
-
Rooms near the attic, roofline, garage, or exterior walls are hard to keep comfortable
-
You feel drafts or notice clear air leakage around penetrations and transitions
-
A renovation or new project has exposed framing that can be insulated
-
An attic, crawl space, rim joist, or other irregular area needs both insulation and air sealing
-
Existing insulation leaves gaps or does not create a continuous boundary
-
You want a professional assessment before choosing between insulation types
The right solution depends on the assembly. EET Insulation will inspect the area and explain the practical options rather than assuming one material fits every space.

What Customers Say About EET Insulation
We had a great experience with EET Insulation. We had old insulation removed in our basement and replaced with spray foam insulation, and added insulation to our existing attic insulation. Elyon was responsive to our concerns during the entire process. His team did a great job and we are very pleased with the work!
Margaret Gilligan
EET Insulation did a fantastic job on my attic project. Elyon and his team were completely professional, efficient, and great to work with. They completed a full cleanout, air sealing, and blew in 16" of new insulation across 1144 SF in just two half-days. They cleaned up perfectly and easily accommodated my requests for attic storage adjustments. I would absolutely use them again!
Jim Barlow
EET did a tremendous job sealing up two drafty bumpouts on our house with spray foam insulation. They did a great job communicating throughout the process. We will not hesitate to contact them in the future for any of our insulation needs.
Curtis Galbreath
Excellent work and I would highly recommend their services. Team arrived ready to work and got the job done all in one day. Elyon guided us thru the entire process and was always available to answer any questions we had. Thanks so much!
Carrie C.
Had Elyon remove my old insulation and seal it and blew in all new insulation and had our attic fan installed all in one day. He and his team did a great job. It has helped our house so well the next day it already felt rebalanced and a bit warmer. I highly recommend him.
Adelina
EET was referred to us by a friend who was also very happy with their services. They insulated above our garage ceiling and their caring, workmanship and attention to detail were first rate. I expect this job to hold up for quite some time to come. I highly recommend them!

Spray Foam Insulation FAQs
Where can spray foam insulation be installed?
Spray foam may be considered for rooflines, attics, rim joists, crawl spaces, walls, and other areas where air leakage and irregular framing are concerns. The appropriate locations depend on the building assembly and project conditions.
Is spray foam right for every home?
No single insulation type is right for every space. Existing materials, ventilation, moisture conditions, access, and the intended thermal boundary should all be reviewed first.
How much does spray foam insulation cost?
No single insulation type is right for every space. Existing materials, ventilation, moisture conditions, access, and the intended thermal boundary should all be reviewed first.
How should I prepare for installation?
Preparation varies by project. EET Insulation will explain access needs, items that should be moved, and when occupants can return to the work area as part of the project plan.
Can spray foam help lower energy bills?
By reducing air leakage and improving the thermal boundary, spray foam may reduce wasted heating and cooling energy. Actual results vary based on the home and its systems.
Should old insulation be removed first?
Not always. Removal depends on the existing material, its condition, contamination, moisture damage, and how the new assembly will be built. We inspect before recommending removal.
