Our radon pump was installed 11 years ago and recently started
squealing. It's a loud noise, so I want to take care of it.
The company that installed this pump no longer exists. There are
only a few radon-installation dealers in the area and they mostly
appear to handle radon problems for businesses.
I wonder whether this type of repair can be handled by other types
of home-repair companies. For example, do furnace repair companies
or plumbers fix radon pumps?
