Insulation Built for Dexter Homes

Seal Tech Insulation has served Dexter and the surrounding Washtenaw County community since 2000, delivering high-performance spray foam and insulation for homes and commercial buildings. Our installers seal air leaks, raise R-value, and help Dexter property owners cut heating and cooling costs by up to 50%.

Dexter combines historic village homes with a growing number of new builds, so we work on both retrofit projects — where existing-wall foam and attic upgrades make older homes efficient — and new construction, where closed-cell spray foam helps builders exceed Michigan energy code. Whether you are upgrading an older home, building new near Ann Arbor, Chelsea, and Pinckney, or improving a commercial property, our team understands the demands Michigan's climate places on a building envelope — and how the right insulation keeps Dexter homes comfortable through cold winters and humid summers.

Two Kinds of Insulation Work in Dexter

Dexter blends 19th-century village homes along the Huron River with a steady stream of new subdivisions on its edges, so insulation work here falls into two camps. Historic Dexter homes tend to have balloon-framed walls, uninsulated attics and significant air leakage that make them expensive to heat. New construction, on the other hand, is an opportunity to build a tight, code-compliant envelope from day one — something Michigan’s energy code increasingly requires.

The fix

How Spray Foam Helps Dexter Homeowners and Builders

For older Dexter and Chelsea-area homes, attic spray foam and injection wall foam deliver a dramatic comfort upgrade without a gut renovation. For new builds, open- and closed-cell spray foam let builders hit R-value targets while air-sealing the whole structure — reducing HVAC sizing and future energy bills. Because we handle both retrofit and new construction, Dexter homeowners and contractors can work with a single insulation partner from the first project to the last.

FAQ

Spray Foam Insulation in Dexter: Frequently Asked Questions

How much does spray foam insulation cost in Dexter, MI?

Cost depends on the size of the area, the foam type (open-cell or closed-cell), and prep work such as removing old insulation. Seal Tech gives every Dexter homeowner a free, no-obligation written estimate after an on-site evaluation, so you know the exact price before any work begins.

Is spray foam insulation worth it for Dexter homes?

Yes. With a mix of historic village homes and newer construction, many Dexter properties have under-insulated attics and drafty walls that struggle against Michigan winters. Spray foam air-seals and insulates in a single step, cutting heating and cooling costs by up to 50%.

Should I choose open-cell or closed-cell spray foam in Dexter?

Closed-cell is usually the best fit for Dexter's climate — it delivers a higher R-value per inch and acts as a vapor barrier. Open-cell is a cost-effective option for interior walls and soundproofing. We recommend the right choice during your free assessment.

How long does a spray foam insulation project take in Dexter?

Most Dexter attic or wall jobs are finished in a single day, while whole-home projects take two to three days. Seal Tech handles all prep, installation, cleanup, and any required permits.
