You’re running out of space. The kids need their own rooms, you need a home office, or that attic is just sitting there collecting dust. Moving sounds exhausting—and expensive. A dormer gives you the square footage you need without uprooting your life.
Here’s what changes: you get actual headroom where you used to duck. Natural light floods in where it used to be dark. That wasted attic becomes a bedroom, office, or whatever you’ve been needing. Your home works for you again.
And if you’re thinking about resale down the road, dormers typically return 65-80% of their cost in added home value. But most homeowners aren’t doing this for the next buyer. They’re doing it because they need the space now and don’t want to leave North New Hyde Park.
We’ve been handling large-scale projects across Nassau County for over 50 years. Dormers, extensions, full renovations—we’ve seen it all, and we know how Long Island homes are built.
What sets us apart isn’t just experience. It’s that Ray is on the job site. Every day. Most contractors send a crew and disappear. We don’t operate that way. You get someone who answers the phone, responds to texts, and shows up when there’s a problem—even at 3 a.m. if your pipe freezes mid-winter.
North New Hyde Park homeowners deal with tight lots, older housing stock, and municipal codes that vary block by block. We know the terrain. We handle the permits, manage the timeline, and keep the site clean while your family is still living there.
First, we come out and look at your attic. Not every roof can support a dormer, and not every dormer makes sense for your layout. We’ll tell you what’s possible, what’s not, and what it’ll cost. No surprises later.
Once you’re ready to move forward, we handle the permits. Nassau County has specific requirements depending on your zone and existing structure. We know what the town needs to see, and we make sure it’s submitted correctly the first time.
Demo and framing come next. We open up the roof, build out the dormer structure, and get it weathertight as fast as possible. Then comes insulation, drywall, windows, and finish work. Most dormer projects take between four and twelve weeks depending on size and scope.
Throughout the process, the job site stays clean. Our crews show up on time, do the work, and don’t leave a mess behind. You’ll know what’s happening and when. And if something comes up, you can reach us. Every time.

Dormers aren’t one-size-fits-all. Shed dormers run across most or all of your roofline and give you the most usable space. Gable dormers are smaller, often used for a single window or to add architectural interest. We’ll walk you through what works for your home and your budget.
You’re also getting structural work that has to meet code. That means proper framing, insulation rated for Long Island winters, and windows that won’t leak when the nor’easters roll through. We use materials built to last because we’re not interested in coming back to fix problems in two years.
On Long Island, a typical dormer addition runs between $15,000 and $50,000 depending on size and complexity. That includes permits, materials, labor, and cleanup. We give you a written quote upfront with a clear timeline. No hidden fees. No scope creep unless you change the plan.
And because we’re a full-service general contractor, we can handle the ancillary work too—new flooring in that attic-turned-bedroom, updated electrical, even a small bathroom if the layout allows it. One crew, one timeline, one point of contact.
Most dormer projects take between four and twelve weeks from start to finish. The timeline depends on the size of the dormer, weather conditions, and how quickly permits move through the town.
Smaller gable dormers that add a single window might be done in a month. Larger shed dormers that extend across your entire roofline take longer—usually closer to ten or twelve weeks. We’re also at the mercy of Nassau County’s permitting process, which can add time on the front end.
Once we’re on site, we move quickly. The goal is to get the structure weathertight as fast as possible so your home isn’t exposed. Then we finish the interior work—insulation, drywall, trim, paint—on a schedule that minimizes disruption to your daily routine. We’ll give you a realistic timeline during the estimate, and we stick to it unless you change the scope or we hit something unexpected during demo.
Yes. Any structural change to your roofline requires a building permit in North New Hyde Park, and Nassau County takes this seriously. The permit process ensures the dormer is built to code and won’t compromise your home’s structural integrity.
We handle the permit application for you. That includes submitting drawings, coordinating with the building department, and making sure inspections happen on schedule. Depending on the town’s workload, permits can take anywhere from a few weeks to a couple of months.
Trying to skip the permit is a bad idea. If you ever sell your home, an unpermitted dormer will show up during the inspection and can kill the deal. Worse, if something goes wrong—a leak, structural issue, whatever—your homeowner’s insurance might not cover it. We do it right the first time so you don’t have problems later.
Yes, but how much depends on the size of the dormer and the overall real estate market. Most homeowners recoup between 65% and 80% of the project cost in added home value. That’s a solid return compared to other home improvement projects.
The bigger benefit is usually quality of life. You’re adding functional square footage without sacrificing yard space or moving to a more expensive neighborhood. For families who need another bedroom or home office, that’s worth more than the resale number.
In North New Hyde Park and the surrounding Nassau County area, buyers are looking for space. Finished attics with dormers check that box. If your dormer is well-built, properly permitted, and blends with the home’s existing architecture, it’s an asset when you eventually sell. Just don’t expect to make money on the project—think of it as getting back most of what you spent while enjoying the extra space in the meantime.
A shed dormer runs horizontally along your roofline and has a single sloped roof. It’s the most common type because it maximizes usable interior space. If you’re trying to turn an attic into a full bedroom or office, a shed dormer usually makes the most sense.
A gable dormer is smaller and has a peaked roof that matches your home’s existing roofline. It’s often used to add a window, create architectural interest, or bring light into a specific area. Gable dormers don’t add as much square footage, but they can improve curb appeal and ventilation.
Which one you need depends on your goals. If you want maximum space, go with a shed dormer. If you’re more focused on aesthetics or just need a bit more headroom in one spot, a gable dormer might be enough. We’ll walk through both options during the estimate and show you what works for your home’s structure and your budget.
Expect to spend between $15,000 and $50,000 for a dormer in North New Hyde Park. Smaller gable dormers are on the lower end. Full shed dormers that span your roofline and include interior finishing are on the higher end.
The cost depends on size, materials, and what you’re doing with the interior space. A basic dormer that just adds headroom and a window costs less than one that includes new flooring, electrical, drywall, and trim. If you’re adding a bathroom or closet, that drives the price up too.
We give you a detailed written quote before any work starts. That includes permits, labor, materials, and cleanup. If we find something unexpected during demo—old wiring that needs updating, structural issues, whatever—we’ll talk to you before moving forward. No surprise bills at the end. You’ll know what you’re paying and what you’re getting.
Not every house is a good candidate for a dormer. The roof pitch, attic height, and existing structure all matter. If your roof is too flat or your attic doesn’t have enough clearance, a dormer might not be feasible—or it might require more structural work than it’s worth.
We’ll assess your home during the initial consultation. We’re looking at roof framing, load-bearing walls, and whether the existing structure can support the added weight. Older homes in North New Hyde Park sometimes have quirks—undersized joists, outdated framing methods—that need to be addressed before we can build up.
If a dormer doesn’t make sense, we’ll tell you. Sometimes a second-story addition or a different type of home extension is a better fit. We’re not here to sell you a project that won’t work. We’d rather give you honest advice upfront than deal with problems halfway through construction.
