How Much Does a General Contractor Cost in Westchester County? (2026 Guide)

Hiring a general contractor in Westchester County costs 20 to 40% more than the national average. That's the reality of building or renovating in one of the most expensive suburban counties in the country. Labor is expensive, permits take longer, and the housing stock is old enough that almost every job uncovers something unexpected behind the walls.

We list 186 general contractors working across Westchester. The competition is real, which is good for homeowners, but the price floor is still high because of what it costs to do business here. Plumbers charge $85 to $175 an hour. Electricians run $60 to $145. A framing carpenter costs $40 to $75 an hour. Your GC is coordinating all of these people, plus pulling permits, scheduling inspections, and managing the timeline.

Here's what projects actually cost.

Westchester has some of the wealthiest zip codes in the country right next to working-class neighborhoods. That range shows up in renovation costs.

Scarsdale is where the numbers get big. Homes are large (3,000 to 5,000+ sq ft), built in the 1920s through 1940s, and owners expect high-end finishes. A kitchen renovation in Scarsdale regularly hits $120,000 to $150,000 because homeowners want custom cabinetry, Wolf or Sub-Zero appliances, and marble countertops. The homes themselves are built well, but the electrical, plumbing, and insulation are often from the original construction and need full replacement once you open the walls.

White Plains has a broader range. Downtown condos need different work than single-family homes in the Gedney neighborhood. Condo renovations are tighter on space and often run into HOA restrictions on construction hours and materials. Single-family homes in White Plains tend to be from the 1950s and 1960s, and renovation costs are closer to the county median.

New Rochelle is mid-range but climbing. The downtown revitalization has pushed property values up, and homeowners are investing in renovations to match. Older colonials near the shore need extra attention to moisture and structural issues. Many of these homes have original plaster walls that cost more to work with than drywall.

Tarrytown and the rivertowns (Irvington, Dobbs Ferry, Hastings-on-Hudson) have charming older homes but tight lots. Getting a dumpster placed, staging materials, and maneuvering equipment through narrow driveways adds cost and time. Permits in the Village of Tarrytown also require Historic Preservation Commission approval for exterior changes to homes in the historic district.

Yorktown Heights and northern Westchester are more affordable for renovations. Homes tend to be from the 1960s and 1970s, lots are bigger, and access is easier. Expect to pay 10 to 20% less than southern Westchester for comparable work.

A general contractor doesn't do all the work themselves. They hire and manage subcontractors (plumber, electrician, tile installer, painter, etc.), buy materials, pull permits, schedule inspections, and keep the project on track. That management and coordination is what you're paying for on top of the actual construction costs.

Most GCs in Westchester charge one of two ways.

Cost-plus means you pay the actual cost of labor and materials, plus a percentage markup. The markup typically runs 10 to 20% in this area. On a $100,000 renovation, you'd pay $110,000 to $120,000 total. The advantage is transparency: you see every invoice from every sub. The downside is that the total isn't fixed, and it can creep up.

Fixed price means the GC gives you one number for the whole job. Their profit is built into that number. You know what you're paying upfront, but you don't see the breakdown. If the contractor estimated well, they make good margin. If they underestimated, they eat the difference (or try to negotiate change orders).

For renovations under $50,000, fixed price is more common. For larger projects, cost-plus with a guaranteed maximum (GMP) is a solid middle ground. The GC has incentive to keep costs down because anything under the cap is split between you.

Architect fees are separate and run 12 to 20% of construction cost for renovation projects. For a $150,000 renovation, expect $18,000 to $30,000 in architect and engineering fees. You don't always need a full architect. For kitchen and bathroom renovations, a kitchen designer ($3,000 to $8,000) paired with a structural engineer ($1,500 to $4,000 for a wall removal) can be more cost-effective.

We list 186 general contractors in Westchester County. Here's how to narrow that list down.

Verify their HIC license with Westchester County Department of Consumer Protection at (914) 995-2155. Ask for a certificate of insurance showing general liability ($1 million minimum) and workers' compensation. Call the insurance company to confirm it's active. These are non-negotiable.

Beyond the basics, look for a contractor who has done your type of project in your part of the county. A GC who specializes in gut renovations of 1930s colonials in southern Westchester understands the problems that come with old plaster, knob-and-tube wiring, and cast iron drain pipes. A GC who builds additions in Yorktown Heights knows the soil conditions and setback requirements up there.

Get three detailed written estimates. Each should break down the scope of work, materials, labor, timeline, payment schedule, and warranty. Compare what's included, not just the bottom line. One estimate might include appliance installation, another might not. One might include a dumpster, another charges extra.

Payment schedules should be tied to milestones (demo complete, rough-in complete, finishes installed), not calendar dates. Never pay more than 30% upfront. In New York, contractors cannot legally collect more than one-third of the total before starting work.

Ask for references from the last 12 months, not just a list of their best projects from five years ago. Call the references and ask if the project came in on budget and on time. Most won't, but how the contractor handled the overruns tells you a lot.

The renovation calendar in Westchester follows a predictable cycle. January through March is the slow season. Contractors are finishing up fall projects and filling their spring schedule. This is the best time to negotiate pricing. Some GCs offer 5 to 10% discounts to keep their crews working through winter.

Interior work (kitchens, bathrooms, basements) can happen year-round. Exterior work and additions depend on weather. Concrete can't be poured below 40 degrees, and roofing shingles won't seal properly in cold weather. If your project involves foundation work or an addition, plan to start in April or May.

Peak season runs May through October. Every good contractor is booked during this stretch. If you want to start a project in June, you should be signing a contract in February or March. Lead times of 8 to 12 weeks for popular GCs are normal during peak season.

Material prices in 2026 are mostly stable compared to the chaos of 2022-2023, but steel and aluminum are up 20 to 30% due to Section 232 tariffs, and concrete is up 4 to 6% because of new EPA regulations. Lumber has settled around $400 to $500 per thousand board feet, which is manageable compared to the $1,500+ spike a few years ago. Locking in material pricing early can save you money if tariff situations change.
