Local insulation contractor
Seal Tech Insulation has served Northville and the surrounding Oakland and Wayne County area since 2000, delivering high-performance spray foam and insulation for homes and commercial buildings. Our installers seal air leaks, raise R-value, and help Northville property owners cut heating and cooling costs by up to 50%.
Northville pairs a historic downtown and older housing stock with newer developments on its edges, which means many homes benefit from retrofit wall foam and attic upgrades while new builds call for high-performance spray foam from the start. Whether you are upgrading an older home, building new near Novi, Plymouth, and South Lyon, or improving a commercial property, our team understands the demands Michigan's climate places on a building envelope — and how the right insulation keeps Northville homes comfortable through cold winters and humid summers.
What we do
Northville is known for its historic downtown and the well-kept Victorian and early-1900s homes around it, alongside newer upscale developments toward Novi and Plymouth. The older homes are charming but leaky — plaster walls, uninsulated cavities and generous air gaps make them costly to heat and prone to cold spots. Newer Northville homes usually have more insulation, but often still lack proper air sealing at the attic and rim joist.
For historic Northville homes, injection wall foam and attic spray foam add insulation and air-sealing without disturbing the original character of the house. For newer homes, sealing the attic plane locks in the comfort and efficiency the home was meant to have. Either way, Northville homeowners get lower energy bills, quieter rooms, and an even temperature from the basement to the top floor.

FAQ
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 Northville homeowner a free, no-obligation written estimate after an on-site evaluation, so you know the exact price before any work begins.
Yes. With historic downtown homes alongside newer developments, many Northville 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%.
Closed-cell is usually the best fit for Northville'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.
Most Northville 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.
