I was called to a home to replace a joint seal under a kitchen sink. The customer had noticed a leak coming from the area and wanted it fixed immediately. I arrived at the house and inspected the area. The seal was old and worn out, and it was causing the leak. I removed the old seal and replaced it with a new one. I also cleaned up the area and made sure that everything was working properly. The customer was very satisfied with the work and thanked me for my help.
