Ask TOH | Microgreens, Elevator

Coming up on this episode of Ask This Old House

Kevin helps a contractor install a home elevator for a young man with disabilities. Jenn Nawada investigates how to grow microgreens. Tom explains the best way to match historic moldings. And Richard diagnoses a problem with well water.


How to Grow Microgreens
Landscape designer Jenn Nawada learns how to grow and harvest microgreens.

Where to find it?

Microgreens are the edible seedlings of vegetables and herbs.  Jenn toured an “urban farm” and learned how to grow them from Tim Smith of We Grow Microgreens. Expert assistance with this project was provided by Nawada Landscape Design


How to Match Historic Moldings

Tom shows off a tool to help match historic moldings in older homes. 

Where to find it?
Tom uses a molding profile jig to show Kevin how to match historic moldings, which is a specialty tool that allows you to trace a profile without removing the molding.

Tom pushes the pins of the jig into the molding and it forms an outline of the molding. Homeowners can then trace the design onto a piece of paper and bring it to a mill shop.

You can either match the molding to one in the mill shop’s stock. Or they could make a molding for you with a custom knife. However, you will have to pay for the custom knife.

Expert assistance with this project was provided by Anderson and McQuaid Co., Inc.  


How to Diagnose Problems with Well Water Systems
Richard examines a homeowner’s high electricity bill and sees a possible connection with her well water.

Richard explains every time a homeowner with a well turns on the faucet, a well water pump could come on and call for water from the well. The well pump should be connected to one of two pressure systems.

One is a large pressure tank. That tank has an air charge at the top and water at the bottom.  The tank is pressurized, so if the pump is coming on and off whenever the faucet comes on, that’s likely an indication that the air charge has become water logged and may need to be recharged.

The second system is similar, but has a neoprene bladder in between the air and the water reservoir. That would form a barrier and negate any oversaturation of the tank. If the pump is coming on in this situation, that means the neoprene bladder or a balloon-like material in between has failed, allowing the air and water to mix.

A well pump that runs to frequently suggests a problem with the pressure systems, which should be inspected and repaired by a qualified well technician. Expert assistance with this project was provided by Webster Enterprises of Westport, MA.


How to Install a Home Elevator
Kevin helps an accessibility contractor install a home elevator for a young man with disabilities.

Expert assistance with this project was provided by accessibility contractor Rick Castino from Operation Independence. The home elevator and elevator enclosure were manufactured by Savaria.
