Census and NOAA figures for the borough of Middlesex in Middlesex County, not the metro, with a source for each.
The median home in the borough of Middlesex was built in 1965, older than the U.S. median of 1980 and older than the New Jersey median of 1970. That is older than the Middlesex County median of 1974.1 Older housing stock means a contractor's first job is finding what is behind the finish - wiring, plumbing and roof decking - before a price is final. The stock is old by national standards: 72% of Middlesex's housing units were built before 1980 (U.S. 50%), and only 8% since 2010. The largest single share, 38%, dates from 1960-1979. That makes it a newer stock than Middlesex County as a whole (57% built before 1980).1 On houses from the 1960s and 1970s, the routine checks are aluminum branch wiring, galvanized supply lines and original single-pane windows.
Owner-occupied homes in Middlesex are older than rentals: a median build year of 1963 against 1973.1 Where owner-occupied homes skew older, a repair-versus-replace conversation is the usual starting point rather than a like-for-like swap. Housing in Middlesex is mostly detached single-family: 67% of units, with 16% 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.
74% of occupied homes in Middlesex are owner-occupied, above the New Jersey share of 64%.1 The median owner-occupied home in Middlesex is valued at $446,400 (ACS), close to the New Jersey median of $454,400. Within Middlesex County the median is $462,900, so Middlesex sits close to it.1 Winters are long: the Somerville Somerset Ap station averages 124 nights a year at or below 32°F and 40 at or below 20°F.2,3 Long winters put freeze-thaw, ice dams and snow load at the center of roofing and masonry decisions.
Summer heat is moderate: about 23 days a year reach 90°F.2,3 Rainfall is substantial: about 45 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 5,385 heating degree days against 859 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.
Middlesex is about 13 miles from the ocean or Gulf coast in a straight line.4,5 Proximity to salt air makes fastener grade and corrosion protection part of every exterior quote. Middlesex sits in IECC climate zone 4A (Mixed-Humid).6 Building permits in Middlesex are normally issued by the borough building department.7,8
