Window Replacement in Gray, Maine

The Census Bureau's American Community Survey estimates about 4,440 housing units in Gray, with a median year built of 1983. Roughly 12 percent predate 1940 and about 18 percent predate 1960, so most of the town is younger than its village center suggests. Two building waves stand out in the data: about 29 percent of homes went up between 1960 and 1979, and about 27 percent in 2000 or later, the years of subdivision growth off the state routes. Close to 78 percent of units are single-family detached houses, and about 82 percent of occupied homes are owner-occupied. The survey also counts roughly 630 seasonal units, around one in seven, which fits the camps and cottages along the town's lake frontage. The older stock runs to Capes and farmhouses, such as the Freeman Farm's circa-1812 Cape with its long ell and 1830s bank barn.

Gray is a cluster of villages: Gray itself, Dry Mills, East Gray, North Gray, South Gray and West Gray. The village center holds the Pennell Institute, an 1876-86 brick Italianate school with a clock tower that now houses the town offices, and Stimson Memorial Hall, a 1900 wood-frame hall fronted by a temple portico on four Tuscan columns. Both are on the National Register, as are the Dry Mills School and the Freeman Farm Historic District. Collyer Brook powered Samuel Mayall's woolen mill from 1791, and its ruins can still be visited. The state's Maine Wildlife Park and fish hatchery are here too, and Little Sebago, Crystal and Forest lakes give the town its shoreline neighborhoods.

Building permits in Gray go through the Community Development Department at the Henry Pennell Municipal Complex, 24 Main Street. The town's residential permit application lists decks as a structure type, asks for a plot plan and building plans, and asks for a Dig Safe number from calling 811 before digging. In the Village Center and Village Center Proper zoning districts, the design standards in Section 402.8.3 of the zoning ordinance, amended in 2021, require a Design Standard Certificate before a building permit is issued for development. Land within 250 feet of a great pond falls under Maine's mandatory shoreland zoning. Confirm what applies with the code office before work starts.

A new window is only as good as the way it is set into the wall. Replacement windows go in either as inserts inside the existing frame or as full-frame units after the old frame comes out; the right choice depends on the condition of the frame, the trim you want to keep, and the siding around it. The site lists vinyl replacement windows and wood or clad units from Andersen, Marvin, Pella and Integrity, in double-hung, casement, picture, bay, sliding and awning styles.

• Each opening is measured and checked for rot in the sill, jambs and framing.
• Old sashes or whole frames come out; damaged wood is repaired before the new unit goes in.
• Units are set level, plumb and square, shimmed, and fastened as the manufacturer requires.
• Low-expansion foam and backer rod seal the gap without bowing the frame.
• Flashing, exterior trim or capping and interior casing are finished so the opening sheds water.

• Fog or condensation between the panes of insulated glass
• Sashes that stick, will not stay up, or let in drafts
• Soft or rotted sills and frames
• Single-pane glass or storm windows you take on and off every year
• Frost or ice on the inside of the glass in winter

• Number of windows, their sizes, and any custom shapes
• Vinyl versus wood or clad units, and the brand and series
• Insert versus full-frame replacement
• Glass package and grille options
• Interior and exterior trim work, and whether siding is open around the opening
