Wall Insulation in Detroit: what to expect
Wall insulation in Detroit often means adding insulation to exterior walls that were built with little or none, which is common in older frame and brick homes in Detroit, Hamtramck, Ferndale and Dearborn. The two paths are insulating closed walls without tearing them open, or insulating open walls during a remodel or siding job.
For closed walls, installers drill small holes between studs from the outside or inside, then dense-pack cellulose or fiberglass, or inject foam, and patch the holes. Blocking, old wiring and balloon framing affect how well cavities fill, so a thermal camera check afterward is worthwhile. Solid brick walls with no cavity are a different case and usually need interior or exterior board instead.
Knob and tube wiring should be checked by an electrician before walls are filled. For open walls see fiberglass batt insulation, and compare Detroit insulation contractors for quotes.
What a proper job includes
- Wall inspection to confirm cavities, framing and any existing insulation
- Check for knob and tube wiring and moisture issues
- Drill and fill plan: exterior or interior access
- Dense-pack or injection foam to fill each cavity
- Hole patching or siding reinstall
- Thermal camera or spot checks for missed cavities
- Written scope of walls covered
What drives the price
- Wall area and number of stories
- Access from outside (siding type) or inside (plaster or drywall)
- Dense-pack cellulose, fiberglass or injection foam
- Framing obstacles such as blocking and balloon framing
- Patching, painting or siding reinstall
- Electrical evaluation before filling
- Open-wall remodel vs closed-wall retrofit

Permits and licensing in Michigan
Insulating closed walls is often treated as an ordinary repair, while insulation in a permitted remodel or addition is usually inspected before drywall. Rules vary, so confirm with the local building department (BSEED in Detroit). In pre-1978 homes, drilling or cutting painted surfaces can disturb lead paint, so ask whether the contractor follows lead-safe work practices.
Paid residential insulation work above a threshold set by state law requires a LARA license: a Maintenance & Alteration Contractor license that lists Insulation, or a Residential Builder license. Check the number on the LARA lookup.
