Protradecraft traveled to Westford, Massachusetts to the home of Building Science Corporation founders Betsy Pettit and Joseph Lstiburek, aka Dr. Joe, to film a replacement window replacement scenario not seen very often.

Removing the old window frame and weight pockets, reframing the rough opening, and flashing a new-construction flanged window into the old existing WRB

Innies, outies, and in-betweenies

An example of why cheap construction is not so cheap

Some original bones and mashed up meat make a door whose secret is safe

Installing a 700-pound window into a second-floor rough opening without a crane

Belt, suspenders, rainscreen, and redundancy make this wall awesome.

Building Resilience is a show about extreme climate construction and houses that can weather the storm through resilient construction and design

A new show about extreme climate construction is interrupted by a global pandemic

Built-in levels make this door easy to plumb, but snap-on jamb and trim covers make it super easy to install

Water management begins with the framing and extends to WRB

Flashing, overlapping, and sealing layers keeps the outside out and the inside in

There is more to an airtight watertight door installation than flashing; adjusting the weatherstripping is critical.
