From Open Framing to a Sealed Envelope
Insulation is technical. Our job is to make it simple. Here's what happens on a Seal Tech job.
Before1. Evaluate & Plan
We assess the building, recommend open-cell, closed-cell, or a mix, and explain the R-values in plain language. Then you get a free written estimate.
During2. Spray & Seal
Our crew preps, protects your space, and sprays. The foam expands to fill every gap, crack, and crevice that fiberglass misses.
After3. Clean Up & Save
We trim, clean up, and handle inspections. You get steady temperatures, fewer drafts, and lower bills for years to come.
The Ultimate Barrier for Michigan Homes
Superior Air Sealing
Spray foam creates a continuous airtight barrier that stops drafts at the source, something traditional fiberglass can't do.
Maximum Energy Savings
A high R-value per inch and no air leaks mean your furnace and AC work less through Michigan winters and summers.
Moisture & Mold Defense
Closed-cell foam acts as a vapor barrier, preventing condensation in wall cavities and protecting your home's structure.
Open Cell vs. Closed Cell Spray Foam
Both stop air leaks. The right choice depends on where it's going and what the space needs to do. We'll recommend the best fit for every area of your project.
Open Cell Foam
Soft, flexible, and budget-friendly, with excellent sound dampening.
| R-value | About R-3.5 to 3.8 per inch |
|---|---|
| Best for | Attics, interior walls, rooflines |
| Bonus | Quieter rooms, lower cost per sq. ft. |
Closed Cell Foam
Dense and rigid, with the highest R-value per inch and built-in moisture resistance.
| R-value | About R-6 to 7 per inch |
|---|---|
| Best for | Exterior walls, crawl spaces, basements, metal buildings |
| Bonus | Vapor barrier and added structural strength |

Spray Foam Insulation FAQs
How much can spray foam lower my energy bills?
Spray foam seals the air leaks that traditional insulation misses, and that can cut heating and cooling costs by up to 50%. Actual savings depend on your home's size, current insulation, and HVAC system.
What's the difference between open cell and closed cell spray foam?
Open cell foam is lighter, more affordable, and great for sound control, at about R-3.5 to 3.8 per inch. Closed cell foam is denser, at about R-6 to 7 per inch. It resists moisture and adds structural strength, which makes it ideal for exterior walls, crawl spaces, and metal buildings.
Can you insulate my existing home without tearing out walls?
Yes. Our Wall Foam retrofit fills existing wall cavities through small access holes, so there's no need to remove drywall.
Is spray foam insulation safe for my family?
The products we install are non-toxic, hypoallergenic, and formaldehyde-free once cured, and they help block pollen, dust, and outdoor pollutants. We follow the manufacturer's re-occupancy guidance and walk you through it before the job starts.
Do you handle permits and cleanup?
Yes. We manage safe removal of old insulation, all city and township building permits, inspections, and post-job cleanup. One call, complete solution.
Is the warranty transferable if I sell my home?
Yes. Our spray foam systems carry a manufacturer-backed Limited Lifetime Warranty that's transferable, so it protects the home, not just the current owner.
What areas does Seal Tech serve?
We serve Southeast Michigan, including Detroit, Ann Arbor, Plymouth, Canton, Brighton, Howell, Monroe, and the Grosse Pointes, plus Lansing and Toledo.
