Replacement windows
67% of homes went up between 1950 and 1979, and most of them have had their original windows replaced since. A replacement window often sits further into or out of the wall than the old one, so the depth you have for an inside mount may differ from window to window in the same house. Measure every opening rather than copying one.
Out-of-square openings
With 74% of homes built before 1980, many openings have had decades to settle. Measure each one's width at the top, middle and bottom, and both diagonals. If the diagonals differ by more than about ¼ inch, add a mounting frame in the designer, or choose an outside mount so the shutter covers the uneven edges.

Dry summers, wet winters
Barely any of the year's precipitation falls in June, July and August; most comes in the cool months. Wood takes on moisture in the wet season and gives it back in the dry one, so expect the panels to feel slightly tighter in winter than in summer. Fit them in the season you're in, and leave the hinge screws a quarter turn from tight until they've been through both.
Fitting them in Concord
Shutter Boys shutters are made for you to fit yourself: an inside or outside mount takes a drill, a level and our step-by-step guide. If you'd rather hire someone, a finish carpenter or blinds installer can fit them; ask on your quote and we'll tell you if we know one near you. You arrange and pay the installer directly.
