Woodbridge's homes and what they mean for siding
Woodbridge Township has about 37,700 homes, and its median build year of 1962 makes it the oldest housing of the five towns we cover. Seven in ten homes (70%) went up before 1980. On a house this age it's common to find more than one layer under the current siding, or soft sheathing at the corners and under windows, and both change the price. A good estimate says up front how the contractor will handle what they find when the old siding comes off. Two in three homes (66%) are owner-occupied, and the median value is about $433,000.
Where you are in Woodbridge matters
Woodbridge is one township made up of many communities: Avenel, Colonia, Fords, Hopelawn, Iselin, Keasbey, Menlo Park Terrace, Port Reading, Sewaren and Woodbridge proper. Several have their own ZIP codes, so people often name the community rather than the township. It is also the oldest original township in New Jersey, chartered in 1669.
What siding costs
There is no official New Jersey figure, but the 2025 Cost vs. Value Report gives national averages: about $17,950 for a vinyl siding replacement and $21,485 for fiber cement. What moves a Woodbridge quote up or down is wall area and stories, trim, soffit and fascia, and what the crew finds under the old siding. See the full New Jersey cost guide →
Permits and paperwork
Replacing existing siding on a one- or two-family home is ordinary maintenance under N.J.A.C. 5:23-2.7, so it normally needs no permit. Polypropylene siding is the exception. Whoever does the work must be registered with the New Jersey Division of Consumer Affairs, show that registration number on the contract, and give you a written contract for anything over $500.
