Survey of old steel windows before they are replaced
Example project
- Home
- 1960s single-story house in Clyde Hill with original steel windows, lived in by its owners
- Original request
- Replace 14 windows and a sliding door
- Testing
- About 8 samples of glazing putty, frame caulk, the door threshold sealant and the board under the picture window
- Found
- Asbestos in the glazing putty of the old steel windows
- Clear
- No asbestos in the caulk, the threshold sealant or the board under the picture window
- Timeline
- One visit by the inspector, then a written report within a few days
- Estimated testing cost
- $650
Scope of work
An accredited inspector's visit, about eight samples with each spot patched, lab fees and a short report that names the positive windows. Taking out the old windows is priced separately.
Project overview
In this example, the owners of a 1960s house in Clyde Hill plan to replace 14 windows and a sliding door. The old steel windows are glazed with putty that has hardened for sixty years, and the window installer asks for a test before the first pane comes out.
Only the glazing putty on the steel windows tests positive. The windows come out as whole units, so the putty is never scraped or broken, and the rest of the job goes ahead without special steps.
The goal
The goal is a clear answer on the windows before the installer books, with the steel windows marked for whole removal.
Process
- Before the visit A list of the windows and doors being replaced, so the inspector samples one of each type.
- Visit About 8 samples of putty, caulk and sealant, each spot patched.
- A few days later Lab results and a short written report naming the positive windows.
- Then The installer plans the steel windows as whole-unit removals, bagged in labeled containers.
Planning right
- Replacement windows can come with their own caulk and foam, so sample what the work will touch.
- Ask the installer to lift a steel window out whole and not to cut or scrape the putty.
- Sample both painted and bare putty if the colors differ.
- Give the installer a copy of the report before the order date.
