Spray foam
Roof decks, framed cavities and assemblies where insulation and air control need to work together.

Home Insulation Services in Greensboro, NC
Seal It plans residential insulation around the part of the home, the intended thermal boundary and the conditions already present. The estimate defines the work before a material is selected.

Start with the work area
What part of the home needs attention?
Homeowners often know where the comfort or moisture problem shows up before they know which insulation product belongs there. Choose the area first. Seal It can evaluate the assembly from there.
01Attic
Review the attic floor, roof deck, ventilation, ductwork and existing insulation before choosing the thermal boundary.
View service →
02Crawlspace
Start with water, ground moisture, vents, plumbing, rim areas and the condition of material already under the floor.
View service →
03Walls
Open framing gives the crew direct access to cavities, penetrations and transitions before drywall or other finishes go in.
View service →
04Retrofit or removal
Existing homes may need damaged material removed, air-sealing access restored or the insulation boundary changed.
View service →The home is a systemSee what the evaluation covers →
Insulation cannot be planned one room at a time.
Heat, air and moisture move through assemblies. A warm upstairs room may point to an attic boundary problem. Cold floors may lead below the home. Condensation can involve humidity, surface temperature and air leakage.
Thermal boundaryWhere insulation separates conditioned space from outside conditions.
Air movementGaps and penetrations can carry heat and moisture through the assembly.
Existing conditionsWater, damaged material and access problems need to be addressed in the right order.
Choose the right approach
Four systems. Different jobs.
No single insulation material is right for every home. The assembly, exposure, available depth, existing material and project stage narrow the choices.
Blown-in
Broad attic-floor coverage, including irregular areas around framing when preparation and depth are controlled.
Existing insulation, air sealing and consistent installed depth belong in the scope.Explore blown-in →
Batt
Accessible framed cavities where the material can be cut and fitted around wiring, plumbing and blocking.
Compression, voids and edge gaps reduce effective coverage.Explore batt →
Removal + retrofit
Wet, contaminated, displaced or damaged material, or projects that require access to the underlying assembly.
The estimate should state what comes out, what stays and what happens next.Explore removal + retrofit →What Seal It looks at
A recommendation starts with the building.
The evaluation connects the homeowner's concern to the physical work area. That keeps the written scope focused on the assembly instead of a generic product list.
- 01Existing conditions
Current insulation, staining, visible moisture, penetrations and repairs.
- 02Building use
How the home and the insulated area are used now and after the work.
- 03Thermal boundary
The surfaces that separate conditioned space from outside conditions.
- 04Access + preparation
Crew access, stored items, old material and work needed before installation.
- 05Written scope
Included areas, material approach, preparation, exclusions and other-trade needs.
Installation quality
The material is only part of the job.
Surface preparation, installed thickness, continuity at transitions and safe work practices affect the finished installation. Qualifying Seal It spray foam projects add ACE monitoring to the application record.

Coverage + preparation
A clear scope makes the finished work easier to judge.
Before installation starts, the estimate should say which surfaces are included, what has to move or come out and where the new insulation boundary will connect.
- Surface readinessRepairs, water entry, stored items and old material are handled in the right order.
- Continuous coverageFraming bays, edges and transitions are part of the installation review.
- Project boundariesIncluded work and exclusions are written down before the crew arrives.
Why the estimate matters
Know what the insulation quote includes.
A useful estimate gives the customer and the crew the same picture of the project. It should identify the work area, preparation, material approach and conditions outside the insulation scope.
- Included surfaces and work areas
- Recommended insulation system
- Preparation and protection
- Removal of existing material
- Crew and equipment access
- Exclusions and repair dependencies
- Applicable project documentation

These answers explain the choices that usually affect residential scope. The final recommendation still depends on the property.
How does Seal It determine which insulation belongs in my home?
The evaluation starts with the part of the building being insulated, the intended thermal boundary, existing material, moisture conditions, access and the way the space is used. The recommendation may involve spray foam, blown-in insulation, batts, removal or crawlspace work depending on the assembly.
Do you provide free home-insulation estimates?
Yes. Seal It provides free estimates for qualifying projects in Greensboro, Winston-Salem and nearby Triad communities. Call 336-490-9521 or use the estimate form.
Is spray foam always better than blown-in or batt insulation?
No single material is correct for every assembly. Spray foam can insulate and control air movement, blown-in material can provide broad attic-floor coverage, and batts can fit accessible framed cavities. Existing conditions, available depth, moisture exposure, access and project goals guide the choice.
Does old insulation need to be removed first?
Removal depends on its condition and the planned work. Wet, contaminated, displaced or damaged material may need to come out. Removal can also be necessary when the crew needs access for air sealing or when the thermal boundary is changing. The estimate should state what remains and what is removed.
Should an attic be insulated at the floor or along the roof deck?
Those approaches create different building assemblies. The attic floor can remain the thermal boundary, or a suitable roof-deck system can bring the attic inside the insulated envelope. Existing ventilation, ductwork, mechanical equipment, roof conditions and current insulation should be reviewed first.
What should a written insulation estimate explain?
A useful estimate identifies the work areas, preparation, existing material, recommended system, access requirements and exclusions. It should also identify conditions that need repair or another trade before insulation is installed.
How is qualifying spray foam work documented?
Seal It uses the Akurate ACE Monitoring System on qualifying spray foam installations. It records temperature, pressure, chemical ratio and gallon counts during application and produces an ACE Report for the customer.
Where does Seal It provide residential insulation service?
Seal It is based in Greensboro and serves qualifying residential projects across the North Carolina Triad. Winston-Salem is a priority service market served from the Greensboro operation. Availability depends on the project address, scope and schedule.
