Norm arrives to find the new windows on site and largely installed. Tom shows him how they matched the original casement details and the operation features. Exterior trim is also going on the building, and Tom walked Kevin through the options the other day. Tom shows Kevin the stock exterior window trim choices available at the local home center, and then an option of making your own (that will last longer) out of cellular PVC if you want a slightly more custom look. They gather supplies to bring back to the Essex house. Norm has the PVC stock glued up, and Tom runs the sill profile on his moulding machine. Richard brings Kevin up to speed on the geothermal installation. The work begins with the drilling of two 350-foot deep wells or "bore holes" using the same rig that drilled our water well last time. The next step is to insert the loops into the closed loop system and grout them in place. Tom shows Kevin the detail for the cedar sidewall shingles that were pre-dipped for longevity and are being installed over cedar breather. We learn how to weave shingles around interior and exterior corners and into the flashing around the windows Tom trimmed out earlier. Roger and Kevin with see how the 5-foot trench for the geo pipes has hit ledge, and what dynamite can do about it. The blasting crew drills 5-foot deep holes into the ledge, fills them with explosives, wires them together and the show ends with a bang!
