Decorative timbers are installed in the new family room; the mahogany deck boards are fastened to the front entry deck; a garden shed is installed in the backyard; closed-cell spray-foam insulation is added to the addition.

In the second half: installing a battery-powered back-up sump pump; repairing a rusty metal railing; storing a wheelbarrow.
