Four samples taken before a patio door is cut into a kitchen wall
Example project
- Home
- 1970s split-entry house in Brooklyn Park with original sheet vinyl in the upstairs kitchen
- Original request
- Replace a kitchen window with a sliding patio door that opens onto a new deck
- Testing
- An MDH-certified inspector takes four samples where the door goes: wall texture and joint compound from the wall, sheet vinyl and its adhesive from the floor
- Found
- Asbestos in the backing of the sheet vinyl
- Clear
- No asbestos in the wall texture, the joint compound or the adhesive
- Timeline
- Under an hour on site, and results in a few days
- Estimated testing cost
- $450
Scope of work
One visit by an MDH-certified inspector, four samples from the wall and the floor where the door goes, accredited lab results and a short report the carpenter can keep with the job. Lifting the positive vinyl at the doorway is quoted on its own.
Project overview
In this example, the owners of a 1970s split-entry house in Brooklyn Park are building a deck off the kitchen. Their carpenter will widen the window opening down to the floor for a sliding door, which cuts through the wall finish and the edge of the old kitchen floor.
An MDH-certified inspector takes four samples from those spots. The wall comes back negative, and so does the adhesive, but the felt backing on the sheet vinyl tests positive. A licensed crew lifts about 20 sq ft of vinyl along that wall before the saw comes out, and the rest of the kitchen floor stays down.
The goal
The goal is a door opening cut through materials the lab has already checked, with the one positive strip gone first.
Process
- First visit An MDH-certified inspector takes four samples and marks each spot on a sketch of the kitchen.
- A few days later The lab report lists all four results, with the vinyl backing the only positive.
- Next After the five-day notice, a licensed crew takes up the vinyl along the door wall.
- Then The carpenter cuts the wall and sets the door.
Planning right
- Tape the outline of the new door on the wall before the inspector comes.
- The vinyl and the glue under it can test differently, so each gets its own sample.
- The report records which materials were sampled and where, which helps if the kitchen is redone later.
- Only the floor along the door wall comes up; the rest can stay under the table.
