Manhasset's housing stock sets the tone for the work. Large colonials on generous lots, many with finished basements, side-hall layouts and decades of past updates, produce renovation projects that are bigger and more finish-driven than the typical starter-home remodel. A kitchen here often means opening three walls. A "bathroom project" is frequently a primary suite. This page walks through the project types we see most in 11030, current planning costs as of October 2026, who issues permits, and how to hire without regret.
The pattern in large colonials is predictable. Houses were built with formal rooms that families now want opened up, kitchens that were designed for a different era and bathrooms that never matched the size of the bedrooms. These are the most common scopes.
A single room project is a sequence. A four-room project is a schedule with dependencies. If the electrician finishes before the framing change is approved, or the floor refinisher starts while the painter is still sanding, quality drops and the budget climbs. The reason many owners of large homes prefer a design-build firm is simple: one schedule, one point of accountability.
The numbers below are typical 2026 planning ranges for the New York metro area. They are not quotes. Scope, finish level, access, hazmat testing and building rules move them, and a written itemized quote governs.
| Project | Typical 2026 planning range |
|---|---|
| Kitchen | $25,000-$85,000+ |
| Full bathroom | $30,000-$60,000+ |
| Mid-level renovation with kitchen and bath | $200-$400 per sq ft |
| Full gut renovation | $250-$500+ per sq ft |
| High-end or structural renovation | $500-$1,000 per sq ft |
| Hardwood installed | $12-$28 per sq ft |
| Hardwood refinishing | $4-$10 per sq ft |
| Interior painting, 3BR equivalent | $6,000-$12,000 |
| Exterior painting, larger or complex house | $12,000-$30,000+ |
Design, engineering and permit costs often add another 15-25% when plans must be filed. Large Manhasset houses commonly reach the top of the exterior painting band when scaffolding, wood repair and multiple coats are involved.

Long Island building permits come from the municipality: town, village or city. Manhasset is an unincorporated hamlet in the Town of North Hempstead, though parts of the surrounding area belong to separate villages with their own building departments. Check your tax bill or ask the town which office covers your parcel.
Surface work such as painting or replacing finish flooring usually does not need a permit. Our permit overview explains the general New York logic, and the municipality gives the final word.
Nassau County requires home improvement contractor licensing through county consumer affairs. Before signing, check the license on the Nassau County website and ask for current insurance certificates. If you want a second opinion on a bid you already hold, send it with your photos and we will compare scope line by line. If a contractor suggests skipping a permit "to save time," walk away: unpermitted work can complicate sales, insurance claims and future refinancing.
Large houses magnify the cost of mistakes. A leak in a primary bath shower ruins a first-floor ceiling below it. An electrical panel upgrade done outside a permit fails inspection when you list the house. Here is where a licensed team earns its cost.
Waterproofing and tile. Showers fail slowly, behind the finish. A membrane system installed correctly, tested and cured is the difference between a 20-year shower and a repair at year three. Waterproofing typically adds roughly $3-$10 per sq ft to the tile line and is worth every dollar.
Structure. Opening a wall between a kitchen and den may involve a beam, a post and a footing. Sizing and inspection require a design professional. N.Y. Renovation Services coordinates the engineer, filing and inspections so the opening is built to the drawing.
Lead and asbestos. Older houses may include lead paint and asbestos-containing materials. Certified work practices protect your family and avoid fines.
Sequence. Tile before floors, floors before final paint, cabinets after rough-in inspection. A professional crew follows the sequence every time.
One accountable team. N.Y. Renovation Services designs, permits and builds in-house, from blueprints to the final coat of paint, with itemized pricing and no hidden fees.
In a large colonial, finishes make up a big share of the visual result and a big share of the budget.
Many Manhasset homes have oak floors that can be refinished rather than replaced. Refinishing is typically $4-$10 per sq ft, compared with $12-$28 per sq ft for new hardwood installed. If boards are structurally sound and thick enough to sand, refinishing saves substantial money. Dust control is critical. Ask whether the crew uses a dustless system and how stairs and adjacent rooms are protected.
Entry floors, mudrooms, kitchens and bathrooms benefit from porcelain or stone. Typical installed floor tile runs $20-$45 per sq ft, shower walls $30-$80 per sq ft, and backsplash $30-$90 per sq ft, with natural stone, large-format panels and mosaics costing more. Substrate flatness drives installation cost, so subfloor prep of about $2-$8 per sq ft is common. On Long Island, our tile installation guide covers materials, labor and what drives estimates.
Painting is where sloppy prep shows. Skim coating damaged plaster adds about $2-$5 per sq ft, and cabinet painting for a kitchen typically runs $3,500-$9,000. A large colonial's interior can quickly outgrow the typical 3BR range, so measure rooms and ceiling heights when comparing bids.
Manhasset's older houses often have wood siding and trim that has been repainted many times. If the home predates 1978, lead may be present in the paint layers. Federal rules require firms paid to disturb paint in these homes to be EPA-certified and to follow lead-safe work practices. The EPA's lead renovation, repair and painting page explains who is covered.
Good exterior painting is mostly preparation. That means washing, scraping, sanding, wood repair, caulking, priming bare spots and finishing with proper coats in appropriate weather. Scaffolding or lifts add cost on two- and three-story elevations. If you plan window replacement or siding repair, schedule those before painting so the paint job is not damaged by later carpentry.
| Stage | Typical time |
|---|---|
| Design, drawings, material selections | 2-8 weeks |
| Permits and approvals | Weeks for simple filings, months for complex ones |
| Kitchen construction | 6-12 weeks |
| Bathroom construction | 3-6 weeks |
| Interior painting, 3BR scale | 2-7 working days or more for large homes |
| Whole-house gut renovation | Several months |
Long-lead items often set the calendar. Windows, custom cabinetry, specialty stone and imported tile can take many weeks to arrive. We recommend ordering after the scope is signed and before demolition begins, so the schedule is real rather than hopeful.
Safety and air quality deserve a line in any plan. Demolition and sanding put fine dust into the air, and the EPA's indoor air quality resources explain how ventilation and containment protect a household during construction. Young children, older relatives and anyone with asthma are the people to plan around, and sometimes the answer is to stay with family for the dustiest week.
Plan for dust, noise and utility shutoffs. A temporary kitchen in a laundry room or basement keeps a family functioning during a kitchen remodel. For a gut renovation, most families relocate. Ask your contractor how heating, water and power will be handled during the project, and how the site will be secured each night.
N.Y. Renovation Services serves Nassau County from its Staten Island base. This page focuses on:
Nearby communities we serve, each with different rules and housing stock:
If you are comparing North Shore neighbors, see our Great Neck renovation guide, which is more focused on co-op boards and village approvals. For South Shore homes, see Rockville Centre. For post-war capes and ranches, read Levittown. The full list is on our Long Island ZIP codes page, and the general overview is at Long Island Renovation Services.
The difference matters when you plan. Manhasset homes are large and finish-heavy, so budgets run higher and trade coordination matters. Garden City projects meet strict village review. Long Beach projects start with the flood map. Hempstead and Mineola houses are smaller and older, with hidden conditions driving risk.

Large-home owners often say they want fewer phone calls and fewer surprises. The way N.Y. Renovation Services runs a project is designed around that.
Walkthrough and measurement. We visit the house, review the systems, take dimensions and discuss how the family lives in the space.
Itemized proposal. Demolition, framing, plumbing, electrical, tile, flooring, painting, cabinetry and cleanup are separate lines. Allowances are labeled. The contract describes what is and is not included.
Permits and approvals. We coordinate the registered design professional and the municipal filing, and we schedule inspections before surfaces are closed.
Clean, protected work areas. Floor protection, dust barriers and daily cleanup are standard in occupied homes.
Close-out. A punch-list walk-through, final cleaning and handoff of documentation.
A giving pledge. We donate 5% of total project cost to a nonprofit you choose.
We are licensed and insured, and we encourage you to verify both. Because tile, flooring and painting are core strengths at N.Y. Renovation Services, finish quality is where our teams spend the most care.
If your Manhasset project is moving from idea to plan, take these steps.
A well-planned renovation in a large colonial, with N.Y. Renovation Services or any qualified firm you choose, gives you a house that works for the next decade. The best results come from honest scoping, proper permits and a team that stays accountable from the first drawing to the last coat of paint.
