Four samples along the cable route for a garage car charger
Example project
- Home
- 1970s split-level house in Minnetonka with the electrical panel in the lower-level utility room and an attached garage
- Original request
- Run a new circuit from the panel to a car charger on the garage wall
- Testing
- Four samples by an MDH-certified inspector: the family room ceiling texture, the taping mud at a ceiling seam, the drywall on the garage wall and the tape on a duct the cable would cross
- Found
- Asbestos in the family room ceiling texture
- Clear
- No asbestos in the taping mud, the garage drywall or the duct tape
- Timeline
- One short visit, with results by email within the week
- Estimated testing cost
- $450
Scope of work
This price covers the inspector’s trip, four samples taken where the electrician’s tape runs, an accredited lab result for every one, and a report that marks each sample spot on a floor plan. Removing the ceiling texture is not part of this price.
Project overview
In this example, a family in a 1970s split-level in Minnetonka has bought an electric car. The electrician’s first plan runs the new cable from the lower-level panel across the family room ceiling and through the wall into the garage.
Before anyone drills, an MDH-certified inspector takes four samples along that path. Only the family room ceiling texture comes back positive. The electrician changes the route up the garage wall, through spaces the samples covered, so the textured ceiling is never cut.
The goal
The goal is a working charger in the garage, with the cable run only through spaces the samples covered.
Process
- First visit With the electrician’s tape marks as a map, an MDH-certified inspector cuts four small samples.
- At the lab The four samples go to an accredited lab and come back with one result apiece.
- A few days later The report comes back with one positive result, in the family room ceiling.
- Then The electrician draws a new route that stays out of that ceiling and books the install.
Planning right
- Have the electrician mark the whole cable route before the samples are taken.
- Texture on top and taping mud beneath are separate materials, which is why they are tested separately.
- Keep the report. It shows what was sampled and where if you plan more work later.
- Taking a positive ceiling down later is licensed work, priced on its own.
