Home Improvement Contractors in Kenilworth, NJ

The median home in the borough of Kenilworth was built in 1955, older than the U.S. median of 1980 and older than the New Jersey median of 1970. That is in line with the Union County median of 1956.¹ 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: 90% of Kenilworth's housing units were built before 1980 (U.S. 50%), and only 6% since 2010. The largest single share, 58%, dates from 1940-1959. That makes it a newer stock than Union County as a whole (78% built before 1980).¹ On houses from the 1940s and 1950s, contractors routinely check for original cast-iron drains, two-wire electrical and undersized panels before pricing a remodel.

Owner-occupied and rented homes in Kenilworth are of similar age: median build years 1956 and 1953.¹ Housing in Kenilworth is mostly detached single-family: 70% of units, with 3% 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 Kenilworth are owner-occupied, above the New Jersey share of 64%.¹

The median owner-occupied home in Kenilworth is valued at $522,200 (ACS), above the New Jersey median of $454,400. Within Union County the median is $529,200, so Kenilworth sits close to it.¹ Home values above the state median tend to support fuller scopes; the written scope should still separate must-do from nice-to-have.
