Title of Treatment: Operational Tune up
Class of Treatment: [x ] Maintain, [ x] Stabilize, [ ] Repair, [ ] Upgrade, [ ] Exception
Type of Treatment: [ x] Traditional, [ ] Contemporary, [ ] Conservation

Condition to be Treated:
<State what is wrong with the window that requires treatment. For example, "Paint is peeling at the sash joint." Or, "A pane of glass is cracked." Upper and lower sash are not operating smoothly.

<Include when this treatment is appropriate, how long you have been using this method, how long it holds up, why it is successful, how it fails, etc.>
This treatment is necessary if the upper and lower sash or not operating smoothly. Windows feel drafty after weather stripping has been installed. I have been using this method for the past 25 years, it’s a tune up that should be done at least every two years. It fails if the tune up is not completed after two years

Typical Procedure:
<Write each step with a short phrase or single sentence. Simply state what is done, you do not need to include all the details of how to do it.>
1. If the windows have pulleys and weights the pulleys should be oiled with a splash of WD40.
2. If one is repainting the sash and window jambs avoid getting paint on the sash cords, it makes them brittle, shortens the life span.
3. Weather Stripping should be examined to make sure it is in its proper place, has not become loose or brittle, if so replace.
4. At the start of the heating season take a very light weight tissue and hold it along the upper and lower sash were it meets the window stop, if it blows around this is a sign of air infiltration so this requires an adjustment of the weatherstripping such as adjusting the window stop to fit tighter against the face of the sash.
5. Check for drafts between the meeting rails, if so most likely the weatherstripping has to be replaced, same for the bottom of the sash were it meets the sub sill.
6. If sash have been painted on the outside or inside, make sure the sash are moving freely, if stuck use a sash saw to cut through the paint film.
7Make sure the bottom of the lower sash is kept painted, this is a venerable area for water to wick up the end grain of the styles.
8. Make sure that the sash lock is well secured so that it pulls the meeting rails tight and snug together stopping any air infiltration.
9. Take a candle wax and rub inside the jamb area were the sash run up and down for a smoother opertaion
10. Make sure that the glazing on the exterior of the sash is intact, if not reglaze as necessary.
11. Scrape and sand any loose paint on the exterior of the sash, jambs and window sill. Apply a oil base primer to any bare wood followed up with a high grade top coat
