Fence Companies in New Castle County, Delaware

The county is really several different fence markets stacked together. In Wilmington, especially in neighborhoods like Trolley Square, Forty Acres and the Highlands, yards are small and often shared with adjoining rowhomes, so six-foot privacy fences and neat aluminum front-yard fences dominate. Alleys, tight access and party fences make these jobs ones where experience matters.

In the suburbs — Newark, Pike Creek, Hockessin, Bear and Glasgow — the typical request is a backyard privacy fence on a quarter-acre lot, often replacing a wood fence that has leaned or rotted after fifteen or twenty years. Further south, Middletown, Townsend and the MOT area have grown fast, and much of that housing sits in HOA communities where the association has a say in style, height and color before a post ever goes in.

Claymont and the Brandywine Hundred area mix older post-war homes with newer townhome developments, while the City of New Castle's historic district has its own character — and its own review process — that can shape what you're allowed to build near the street.

Unincorporated New Castle County regulates fences through its Unified Development Code, which sets height limits and rules about how close a fence can sit to property lines and sight triangles at corners. The City of Wilmington, Newark, Middletown and other incorporated towns run their own zoning and permit processes, so the rules that apply to your neighbor across a municipal line may not apply to you.

As a rough pattern in the county, backyard fences up to about six feet are often allowed without much fuss, while front-yard fences face stricter height and openness limits. Corner lots get extra scrutiny because of visibility at intersections. If your home is in a planned community — and much of Bear, Glasgow and Middletown is — expect the HOA to require an application, a site plan and sometimes a specific approved style before work starts.

In Old New Castle's historic district, exterior changes including fences can require review by the historic commission. Wherever you live, get the approval question answered before signing a contract, and ask each fence company whether they pull the permit or leave that to you.

New Castle County soil runs heavy on clay, especially in the Piedmont areas north of the Chesapeake and Delaware Canal around Hockessin and Pike Creek. Clay holds water, heaves in freezes and can push shallow posts out of plumb over a few winters, so post depth and proper concrete footings matter more here than in sandy Sussex County.

Slopes are common in the northern suburbs, and a good installer will step or rack panels to follow the grade instead of leaving gaps a dog can slip under. Mature trees are another local constant: roots along a fence line slow digging and sometimes force the line to jog. In older Wilmington neighborhoods, expect tight side yards, limited equipment access and the occasional buried surprise from a century of previous owners.

Shared fences are the norm in dense neighborhoods. If a fence sits on the line between you and a neighbor, talk to them first — many homeowners split the cost, and even when they don't, a heads-up avoids disputes over the property line. A survey is the only reliable way to confirm where the line actually runs.

Vinyl privacy is the default in the newer suburbs because it needs almost no upkeep and survives the freeze-thaw cycle without rotting. Pressure-treated wood privacy remains popular for its lower upfront cost and natural look, especially in established Newark and Pike Creek neighborhoods. Aluminum shows up around pools and in front yards where HOAs want an open look, and black vinyl-coated chain link is the budget workhorse for side yards, dog runs and larger lots toward Townsend.

Prices in the county tend to run slightly above the Delaware average because lots are tighter, labor demand is higher and older neighborhoods add access challenges. As rough planning numbers, installed chain link often lands around $16 to $32 per linear foot, wood privacy around $24 to $45, vinyl privacy around $32 to $60 and aluminum around $34 to $68. Gates, old-fence removal, slopes and root-heavy digging all add to that.

For a fuller breakdown by material and yard size, see our Delaware fence cost guide. The only reliable number is the one in a written quote after an installer has walked your yard.

Ask every company for proof of insurance and a current Delaware business license, and confirm who handles the permit and any HOA paperwork. A solid written estimate names the material grade, post size and depth, gate hardware, removal of the old fence and cleanup. Be cautious of any quote given sight-unseen for a yard the installer hasn't visited.

Before digging starts, call 811 so Miss Utility can mark public utility lines — it's free and required. Private lines like irrigation, landscape lighting and invisible dog fences aren't marked, so point those out to the crew.
