Norm and Kevin arrive to find the painters putting up a tinted primer with airless sprayers, turning the house from grey to a sunny yellow. Inside, Tom and Norm get to work trimming out the double hung widows on the second floor with an elegant, modern detail specified by the architect. Back outside, Norm finds custom gutter fabricator Augustin Crookston on site again to form and install the custom copper half-round gutters for the project. Richard meets fireplace specialist John Sullivan to see the Danish-designed zero-clearance wood burning fireplace insert he's providing for the living room. In the second half of the hour, on ASK THIS OLD HOUSE, Tom installs interior window trim. Then, Richard installs a new device that will heat a swimming pool for free using the excess heat produced by a central air conditioner.
