Aging-in-Place Remodelers in Wilmington, DE: Stairs, Licenses

New Castle County had 110,835 residents 65 and over on July 1, 2025, 18.8% of the county, the largest count in Delaware and the lowest share (Census Bureau Vintage 2025 estimates). In the city of Wilmington, where the median home was built in 1946 and only 10% of homes are detached (Census ACS 2024 5-year), aging in place means stairs: the front stoop, the staircase to the only bathroom, and 20.2 inches of snow a year on both. A remodeler here holds a Delaware business license and Department of Labor registration, plus a New Castle County contractor license in unincorporated areas such as Hockessin. The projects that come up most are stair lifts, a first-floor bathroom or bedroom, and railings on the stoop.

Wilmington by the numbers

• 15.5% of Wilmington residents are 65 or older, 11,083 people; the median home was built in 1946 and 10% of homes are detached (Census ACS 2024 5-year).
• The suburbs differ: Hockessin is 26.5% residents 65 and over, with a 1981 median build year and 84% detached houses; Newark is 11.2% (median 1978) and Middletown 15.4% (median 2005) (Census ACS 2024 5-year).
• Wilmington averages 20.2 inches of snow on 10.7 days a year (NCEI 1991 to 2020 normals).

The homes here

The Wilmington rowhouse. A 1940s rowhouse usually has one bathroom, upstairs, every bedroom up the same staircase, and a stoop of several steps at the front. That stoop needs more ramp than a city lot has room for (1 foot of ramp per inch of rise), so the usual answers are handrails on both sides, a non-slip tread, or a rear entry at grade. Inside, the choice is a stair lift on the main staircase or a main-floor bedroom and bath built into the back of the first floor, the bigger project but the one that ends the stairs question for good.

Hockessin, Newark and Middletown. Detached suburban houses from the late 1970s and early 1980s (Newark 1978, Hockessin 1981) and the 2000s (Middletown 2005). The older ones have the bathroom of their era: a tub-and-shower combination, a standard door, a towel bar where a grab bar should be. If the bedrooms are upstairs the choice is the same as in the city; if not, the work is the bathroom and the entry.

Winter. 20.2 inches of snow on 10.7 days a year (NCEI 1991 to 2020 normals) means an outdoor ramp or stoop needs a non-slip surface, handrails on both sides, somewhere to put the shovelled snow, and ideally a roof over the landing.

Licensing and permits in New Castle County

Delaware has no statewide general contractor license. The state credentials are a Division of Revenue business license and a Department of Labor contractor registration (look it up at the state contractor registry), plus Division of Professional Regulation licenses for the plumber, HVAC contractor and electrician, checkable on DELPROS. New Castle County goes further than Sussex or Kent: work in unincorporated areas, Hockessin included, needs a county contractor license, permit-endorsed for building, plumbing and HVACR work, with an online lookup and a licensing office at (302) 395-5420. The city of Wilmington requires a city business license with the state license attached, and tests its own plumbing and HVAC licenses. Inside Newark or Middletown, ask the city permit office what it adds. The state picture, including the Attorney General's written-contract rules, is on our Delaware page.

Who pays

Most families here pay directly, from savings, home equity or siblings splitting the cost; paying out of pocket explains the tools and the milestone payment schedule. The Statewide Emergency Repair Program, run by Milford Housing Development Corporation, covers grab bars and ramps for owner-occupants of a year or more with income at or below 80% of area median and an immediate health or safety need. New Castle County's Department of Community Services runs a senior home repair program for homeowners outside Wilmington and Newark covering grab bars and accessibility work, plus an Architectural Accessibility Program; call the department to ask what is open. Some Medicare Advantage plans add a bathroom safety allowance and many long-term care policies include a home modification benefit (Medicare and Medicare Advantage, long-term care insurance), and the Division of Medicaid and Medical Assistance answers Medicaid coverage and waitlist questions. The Delaware Aging and Disability Resource Center, 1-800-223-9074, is the first call.

Common projects in Wilmington

• Stair lifts: $3,000 to $20,000 installed nationally, averages $7,000 to $8,000. A straight rowhouse staircase takes a straight rail, the cheap end; a turn or landing needs a curved rail.
• Main-floor bedroom and bath: cost varies by home; whether a room exists to convert and how far the new bathroom sits from existing plumbing drive it.
• Bathroom safety remodel: $6,600 to $28,000 for the full accessible bathroom, $2,500 to $9,000 for a curbless shower conversion.
• Grab bars and railings: stoop railings on both sides and bathroom grab bars. The hardware is inexpensive; proper anchoring is the cost.
