The median home in the community of Triangle was built in 1998, newer than the U.S. median of 1980 and newer than the Virginia median of 1984. That is newer than the Prince William County median of 1995.1 A large share of newer homes means many systems are still inside a warranty; checking that comes before any repair quote. Triangle's housing is newer than the national mix: 36% of units predate 1980 against 50% nationally, and 15% date from 2010 or later. The largest single share, 33%, dates from 2000-2009. That makes it a newer stock than Prince William County as a whole (24% built before 1980).1 On houses from the 2000s, the common first-time jobs are the first roof replacement, original water heater and HVAC, and warranty paperwork on anything still covered.

Owner-occupied homes in Triangle are newer than rentals: a median build year of 2003 against 1977.1 With owner-occupied homes skewing newer, many requests are first-time replacements of original builder-grade components. Housing in Triangle is mostly detached single-family: 60% of units, with 21% in buildings of five or more units.1 A mostly detached stock means the full range of exterior work applies: roofs, garage doors, chimneys and backyard units.

63% of occupied homes in Triangle are owner-occupied, below the Virginia share of 67%.1 The median owner-occupied home in Triangle is valued at $505,300 (ACS), above the Virginia median of $383,700.

Summers bring about 30 days a year at or above 90°F.2,3 Rainfall is substantial: about 41 inches a year, 10 days of it an inch or more.2,3 Heavy rainfall makes flashing, drainage and ventilation details the difference between a sound assembly and a wet one. Heating dominates the year: about 4,002 heating degree days against 1,512 cooling degree days (base 65°F).2,3 In a heating-led climate, insulation and air sealing carry most of the energy-code weight for any work that opens the envelope.
