Samples from cracked wall and ceiling joints after a foundation was leveled
Example project
- Home
- 1950s single-story brick house in Dallas on a slab, about 1,700 sq ft
- Original request
- Patch and repaint the cracks that opened at door frames and corners after the foundation was leveled
- Testing
- Eight samples: hall and bedroom wall joint compound, ceiling texture and the older patches at the door frames
- Found
- Asbestos in the wall joint compound in the hall and two bedrooms
- Clear
- The ceiling texture and the newer patches around the door frames
- State notice
- None for a private home
- Cost
- $550
Scope of work
A visit to mark each cracked joint, eight small samples taken with a mist of water at each spot, a lab report with the results marked on a plan of the house, and a short note for the painter on which walls to leave alone until the positive joints are dealt with. Repairs and paint are separate.
Project overview
In this example, the owners of a 1950s brick house in Dallas have the foundation leveled with piers, and cracks open at door frames and in a few corners. They plan to patch and repaint the rooms themselves and ask for tests first, since sanding a patch is the quickest way to put dust in the air.
Eight samples go to the lab. The joint compound on the hall and bedroom walls comes back positive, while the ceiling texture and the newer patches at the door frames are clear. The painter is told which walls to leave closed, and the three positive walls are priced as a separate job.
The goal
The goal is a plan showing which cracks can be patched now and which walls need a crew first.
Process
- Visit Cracks marked on a plan of the house and eight spots sampled, each misted first.
- Results A written report with the positive walls marked on the plan.
- Before patching The owners and the painter told which walls to leave alone.
- Then Positive joints cleared by a crew before any patching, or a different repair chosen.
Planning right
- Test before anyone patches. Sanding cracked compound is the step that puts dust in the air.
- Ask for samples at the corners that cracked, not only at a flat piece of wall.
- Newer patches are sampled apart from the original compound. Here only the original is positive.
- Keep a copy of the report for the next contractor who opens a wall.
