You’re not just getting updated rooms. You’re getting a home that finally works the way you need it to—more space where it matters, systems that don’t fail in the middle of winter, and a layout that makes sense for how you actually live.
A full house renovation means addressing everything at once. No more patching problems or living with “good enough.” When we gut and rebuild, you get new electrical that can handle modern appliances, plumbing that won’t freeze when temperatures drop, and insulation that keeps your heating bills reasonable on Long Island.
The result is a home you’re not constantly fixing. One that holds its value in a market where median home prices hit $999K and buyers expect quality. One where you’re not calling contractors every few months because something else broke.
Ray Coleman Home Improvement has been handling full house renovations across Nassau and Suffolk County for over 50 years. That’s not a marketing line—it’s just how long we’ve been showing up, doing the work, and answering the phone when homeowners need help.
We rank in the top 1% of New York’s 77,888 licensed contractors according to BuildZoom. We hold multiple licenses through Nassau County. And Ray himself is on every job site, working alongside the crew—not just managing from an office.
Manorhaven homeowners deal with the same challenges as the rest of Long Island: older homes that need serious updates, competitive renovation costs that run $150-$250 per square foot, and winters that test every pipe and heating system. We’ve handled all of it, and we know what it takes to get your project done right.
First, we walk through your home and talk about what you want to change. Not what we think you should do—what you actually need. We discuss budget, timeline, and whether permits are required. If you want to work with architects to redesign from scratch, we coordinate that. If you already know what you want, we move forward.
Once we agree on scope and price, we schedule the work and show up when we say we will. Our crew arrives, sets up, and starts demo if it’s a gut renovation. Every day, we clean up before we leave. No debris piling up, no mess left for you to deal with.
Throughout the project, you can reach Ray directly. Call, text, whatever works. If something comes up—and it often does in older homes—we handle it. We’ve dealt with outdated wiring, asbestos, foundation issues, and all the surprises that come with homes built decades ago. When the work is complete, it’s done on time, as promised, and you’re not chasing us for punch list items.

A whole house renovation with us covers the big stuff: kitchen and bathroom remodels, first-floor renovations, extensions, dormers, and structural changes that open up your layout. We handle electrical upgrades, plumbing replacement, HVAC work, insulation, drywall, flooring, and finishing.
On Long Island, where full gut renovations run between $150,000 and $250,000 for a typical 1,000-square-foot project, you need to know exactly what you’re paying for. Our pricing is transparent. We walk you through the numbers, explain where costs come from, and don’t surprise you with add-ons halfway through.
We also handle the permit process when required, coordinate inspections, and manage all the subcontractors. You’re not juggling five different companies or trying to schedule electricians around plumbers. We manage it all, and our crews show up professional, clean, and respectful of your home. With over 80% of U.S. homes older than 20 years, and Manorhaven’s housing stock reflecting that age, most renovations uncover issues. We’re ready for them.
Most whole house renovations take three to six months, depending on the scope. A first-floor gut renovation with kitchen and bathroom remodels usually runs four to five months. If you’re adding extensions or dormers, expect closer to six months or more.
Timeline depends on a few things: permit approval if required, material availability, and how much structural work is involved. Older Long Island homes often have surprises—outdated electrical, plumbing that needs replacement, or foundation issues that weren’t obvious until demo. We build buffer time into schedules because we’ve done this long enough to know what to expect.
We don’t rush jobs to move on to the next one. Every project gets completed right, on the timeline we agreed to. Our customers consistently mention that we finish when we say we will, and that’s not common in this industry.
On Long Island, you’re looking at $150 to $250 per square foot for a full gut renovation. A 1,000-square-foot project typically costs between $150,000 and $250,000. That’s significantly higher than the national average of $75 to $185 per square foot, but Long Island’s cost of living, labor rates, and material costs drive those numbers.
Your final cost depends on finishes, structural changes, and how much of the home you’re renovating. High-end kitchens and bathrooms increase costs. Adding square footage through extensions or dormers adds more. If we’re working with existing layouts and mid-range finishes, costs stay on the lower end.
We give you a detailed estimate upfront. No vague ranges or surprise bills later. More than three in four homeowners go over budget on renovations, with 44% exceeding by at least $5,000. We avoid that by being clear about costs from the start and communicating immediately if something changes.
It depends on what we’re renovating. If it’s a first-floor renovation and you have a second floor with a bathroom, yes, you can stay. If we’re gutting your only kitchen and bathroom, it gets much harder. Most homeowners doing whole house renovations move out temporarily.
Living through construction means no kitchen for weeks or months, limited bathroom access, dust even with containment efforts, and noise during work hours. In smaller Long Island homes where space is already tight, it’s tough. You’re also in the way when crews need access to every room.
If you do stay, we keep the site as clean as possible and establish a daily cleanup routine. We’ve had clients stay through first-floor renovations successfully, but it requires flexibility and patience. We’ll be honest about whether it’s realistic for your specific project.
Yes, we handle permits when your project requires them. In Nassau County, most structural work, electrical upgrades, plumbing changes, and additions need permits. We pull them, coordinate inspections, and make sure everything passes code.
Permit timelines vary. Some approvals come through in a few weeks; others take longer depending on the scope and the municipality’s workload. We factor permit time into your project schedule so you’re not surprised by delays.
We prefer jobs that don’t require permits when possible because they move faster, but we never skip permits when they’re required. It’s not worth the risk to you or your home’s resale value. Unpermitted work can kill a sale or force you to rip out completed renovations to get retroactive approvals.
We deal with them. Older homes almost always have surprises once walls come down—outdated wiring that’s not up to code, plumbing that’s corroded, structural issues, sometimes asbestos or mold. It’s not a matter of if, but when.
When we find something, we stop, assess it, and call you immediately. We explain what we found, what it means for the project, and what it costs to fix. You decide how to proceed. We don’t just keep going and bill you later.
Our 50 years of experience means we’ve seen most issues before. We know how to handle them efficiently and correctly. We also build contingency into budgets when we’re working on older Long Island homes because we know the likelihood of finding something. That way, you’re not blindsided by a $10,000 surprise.
Because we answer the phone. Because Ray is on your job site every day, actually working. Because we’ve been doing this for over 50 years and rank in the top 1% of New York contractors. And because our customers say we do what we promise.
You’re not hiring a company that disappears after signing the contract. We’re available when you call or text. If you have a frozen pipe emergency at 3 a.m., Ray shows up. If you have questions mid-project, you get answers immediately.
We also keep job sites clean, finish on time, and don’t surprise you with costs. In a market as competitive and expensive as Long Island, where renovation budgets easily hit six figures, you need a general contractor you can trust. We’ve built that trust with homeowners across Nassau and Suffolk County for five decades.
