One of the most common questions homeowners ask before starting a kitchen remodel is simple: how long is this actually going to take? The honest answer depends on your kitchen's size, the scope of work, material lead times, and permit processing in your municipality — but for a full gut renovation on Long Island, most projects run 8 to 14 weeks from demolition to final walkthrough. Cosmetic refreshes with no structural or plumbing changes can land closer to 4 to 6 weeks. Here is what a realistic week-by-week breakdown looks like.
Before Week 1: Planning, Design, and Permits
The weeks before a hammer swings are the ones that determine whether your project finishes on time or drags into next season. This phase typically runs 4 to 8 weeks and includes:
- Design and layout decisions — cabinet configuration, appliance placement, island dimensions, workflow. Working with a design-build contractor keeps drawings and construction under one roof and avoids miscommunication between separate parties.
- Material selection and ordering — cabinets are often the longest lead item. Semi-custom and custom cabinetry from most manufacturers runs 4 to 8 weeks; stock cabinets can ship in days. Countertop slabs, specialty tile, and appliances add their own lead times.
- Permit applications — in Nassau and Suffolk Counties, any work that touches electrical, plumbing, structural walls, or HVAC requires permits. Suffolk towns like Babylon, Islip, and Huntington process residential permits in roughly 2 to 4 weeks for straightforward work; more complex projects or those requiring variance review take longer. Your contractor pulls these — never skip them. Unpermitted work creates serious problems at resale and with homeowner's insurance.
Do not schedule demo until cabinets are confirmed in production and all permits are in hand. This is the single biggest cause of mid-project delays.
Weeks 1 to 2: Demolition and Rough Work
Once the permits are posted and materials are either on-site or confirmed shipping, work begins.
- Demo (Days 1 to 3): Existing cabinets, countertops, flooring, and sometimes soffits come out. If you are opening a wall, this is when structural work — temporary shoring, LVL beam installation — happens. A licensed demolition crew handles debris removal and protects adjacent spaces.
- Rough plumbing (Days 2 to 5): If the sink is moving, a drain line is being added for an island, or you are upgrading to a larger capacity line, rough plumbing happens now while walls are open. Milton's Construction carries a licensed plumbing team — see our plumbing services — which means no waiting on a sub to show up and no coordination gaps.
- Rough electrical (Days 3 to 6): New circuits for the refrigerator, dishwasher, microwave, and island receptacles are rough-wired before walls close. Most Long Island kitchens built before 2000 need a panel upgrade or at minimum new dedicated circuits to meet current NEC requirements.
- HVAC rough-in (if applicable): If you are adding or relocating supply registers, or installing a ductless mini-split for zone comfort — a popular upgrade in older Long Island homes with inadequate kitchen ventilation — the rough-in happens during this window.
Rough inspections are scheduled at the end of this phase. Do not close walls until inspectors sign off.
Weeks 3 to 4: Drywall, Flooring Prep, and Cabinet Installation
- Insulation and drywall: After rough inspections pass, walls and ceilings are insulated (important on exterior kitchen walls, especially on Long Island's North Shore where wind exposure is significant) and drywalled. Skim coat and paint prep follow.
- Flooring substrate: Depending on your finish floor choice — tile, hardwood, LVP — the subfloor is leveled and prepared. In older Long Island homes, this sometimes surfaces rot or out-of-level conditions that add a day or two.
- Cabinet delivery and installation: This is the milestone the whole schedule is built around. A standard kitchen takes 1 to 3 days to set cabinets depending on complexity. Crown molding, filler strips, and hardware installation add another half-day to a day.
Weeks 5 to 6: Countertops, Tile, and Trim
- Countertop templating and fabrication: Stone countertops (quartz, granite, marble) are templated after cabinets are set and fabricated off-site — typically a 5 to 10 business day turnaround. Installation takes a few hours. Laminate and butcher block can install faster.
- Backsplash tile: Once counters are in, tile work begins. A standard backsplash runs 1 to 2 days for installation, plus grout cure time.
- Trim carpentry: Window casing, base molding, and any built-in shelving or bench seating is completed during this window.
Weeks 7 to 8: Finish Work and Final Inspections
- Finish plumbing: Sink, faucet, disposal, and dishwasher connections are completed.
- Finish electrical: Outlets, switches, under-cabinet lighting, and fixtures are installed and energized.
- Appliance installation: Built-in appliances — range, hood, refrigerator panels — are set and tested.
- Flooring finish: If hardwood was deferred to protect it during other trades, it installs now. Final paint touch-ups follow.
- Final inspections: Electrical, plumbing, and building final inspections are scheduled. Suffolk and Nassau towns typically schedule these within 1 to 2 weeks of request. Your certificate of occupancy or certificate of completion closes out the permit.
What Can Extend Your Timeline
A few factors consistently push schedules on Long Island projects:
- Asbestos or lead paint remediation in pre-1980 homes — common in West Babylon and surrounding communities — adds 3 to 7 days and requires licensed abatement.
- Structural surprises: undersized headers, rot in exterior walls, or out-of-plumb framing add time to rough work.
- Material back-orders — particularly cabinets and appliances, which have faced extended lead times since 2021 and still require early confirmation.
- Permit processing delays in municipalities with high application volume. Your contractor should be tracking this proactively, not reactively.
For homeowners considering a larger scope alongside the kitchen — an addition or open-concept expansion, or a frame-to-finish new construction project — the planning phase is even more critical and timelines extend accordingly.
