Four samples along the route of a gas line for a standby generator
Example project
- Home
- Two-story Apple Valley home from the 1970s; the basement is finished
- Original request
- Run a gas line from the meter through the basement to a standby generator outside
- Testing
- Four samples by an MDH-certified inspector: the basement ceiling texture, the family room wall joints, the utility room wall and the utility room floor tile
- Found
- Asbestos in the basement family room’s sprayed ceiling
- Clear
- No asbestos in the wall joints, the utility room wall or the floor tile
- Timeline
- An hour on site, and lab results later that week
- Estimated testing cost
- $450
Scope of work
An MDH-certified inspector’s visit, four samples taken where the plumber meant to drill or cut, a lab result per sample and a brief report. Taking down the positive ceiling texture would be priced separately; in this example the line is rerouted instead.
Project overview
In this example, a long power outage convinces an Apple Valley couple to add a standby generator to their 1970s house. The plumber’s first plan runs the new gas line across the finished basement ceiling and out through the rim joist.
An MDH-certified inspector goes over that path first and samples it in four places. Only the sprayed texture on the basement ceiling is positive. The plumber moves the route into the unfinished utility room, where the ceiling is bare joists, so the texture is never touched.
The goal
The goal is a working generator with the gas line in open framing and the textured basement ceiling left as it was.
Process
- First visit The plumber shows an MDH-certified inspector each planned hole, and four samples go to the lab.
- A few days later The report comes back: one positive ceiling, three clear materials.
- Next The plumber redraws the route through the utility room and the open joists.
- Then The gas line and the generator go in with no ceiling cut.
Planning right
- Have the installer mark every hole on the route before the inspector arrives.
- Sometimes a different route avoids a positive material, so ask about one before you book removal.
- An intact textured ceiling that nobody will cut can stay as it is.
- Keep the report with your house records; it lists what was tested and the spot each sample came from.
