Build it into your project calendar. 03 #### Home type drives cost Cape, Ranch, and Split-Level homes each carry different structural considerations that change the math. 04 #### Organized by scope tier Scope drives cost more than square footage. Every guide is organized that way, not by sq ft alone. 05 #### Costs published openly Most Long Island contractors won't publish numbers. Homeowners who understand costs upfront make better decisions. What These Guides Cover ## Different guides for different planning questions Center Island Contracting's pricing guides span the most common residential renovation and addition projects on Long Island. Each guide is built around a different entry point, depending on how much a homeowner already knows about their project, so you can start with the question you actually have. Some guides are structured by **scope tier**: from a direct-replacement update within an existing footprint to a full reconfiguration or net-new space carve-out. Others approach cost differently. The Dormer & Addition guide organizes pricing by **home type** (Cape, Split-Level, Ranch). The Home Addition guide organizes by **budget bracket**, which serves homeowners who know roughly what they want to spend but haven't yet defined a structural scope. The Center Island Contracting Showbook serves a different purpose. It is not a pricing resource; it is a visual record of completed Center Island Contracting projects designed for homeowners in the design phase who want to see execution quality before committing to a consultation. The Pricing Guide Library ## Read the guide that pertains to your upcoming project Each guide uses a different scope model because each kind of project answers a different planning question. Start with the one that fits. 01 ### Long Island Bathroom Remodel Pricing Guide Three scope tiers: a direct replacement within an existing three-piece layout, a reconfigured layout within the current footprint, and a net-new bathroom carved from adjacent square footage. Covers how permit requirements, material selection, and structural conditions affect cost. #### $40K-$130K+ [Read the Bathroom Pricing Guide](https://centerislandcontracting.com/guides/long-island-bathroom-remodel-pricing-guide/) 02 ### Long Island Kitchen Remodel Pricing Guide Kitchen costs broken down by scope, from a cabinet and surface refresh to a full layout reconfiguration with structural modifications.

Built for homeowners evaluating our design work before reviewing cost. The Showbook is a curated visual guide to completed projects across our full range of services: kitchens, bathrooms, additions, new construction, and whole-house renovations. It is intended for homeowners in the design phase who want to evaluate execution quality and aesthetic range before scheduling a consultation. [View the Showbook](https://centerislandcontracting.com/guides/2025-cic-showbook/) How These Guides Work Together ## Companion documents that overlap by design Two pairs of guides answer two different planning questions. Pick the right entry point and the other guide becomes the cross-reference. Pair 01 · Kitchen & Bath ### Bathroom + Kitchen. A three-tier scope model in both directions Both guides belong to the Kitchen & Bath service line, both use a three-tier scope model, and both address the same core cost variables: footprint, permit complexity, material tier, and structural conditions. A homeowner planning a primary suite renovation may find both guides useful, since master suite projects frequently involve both spaces. 01 · Bath $40K-$130K+ → 02 · Kitchen $85K-$280K+ → Pair 02 · Home Additions ### Dormer + Addition. Overlap in the $120K-$200K range If you already know your home type and want to understand what a second story or rear dormer will cost on a Cape or Ranch, start with the Dormer guide. If you are working backward from a budget number and want to understand what that budget will buy in terms of addition scope, start with the Home Addition guide. 03 · Dormer $120K-$600K+ → 04 · Addition $50K-$200K+ → Where Every Guide Leads Every pricing guide leads to the same next step: a Project Development Agreement (PDA) with Center Island Contracting, which turns a budget range into preliminary floor plans, 3D renderings, specifications, a scope of work and construction pricing.

These guides provide the numbers that most contractors will not give you until you've signed a contract.

Each guide accounts for them, and is updated to reflect what Center Island Contracting is actually bidding and building, not what national cost databases report. ### Labor Premium Labor costs in Nassau and Suffolk Counties are meaningfully higher than the national average, and that gap doesn't close at any scope tier. ### Permit Variance Nassau and Suffolk towns process permits through different departments and on different timelines. Oyster Bay, Huntington, Babylon, Hempstead and others each add their own pace. ### Housing Stock The prevalence of Cape-style and Ranch homes on Long Island creates structural constraints that don't exist in newer construction markets, and those constraints directly affect addition cost. ### Material Conditions 2026 material pricing reflects post-pandemic supply chain normalization plus continued premium pricing for quality-tier finishes. Each guide accounts for what Center Island Contracting is actually bidding and building. Not Sure Which Guide Applies to Your Project? ## Skip the reading. Talk to a builder.
