You get usable space where there wasn’t any before. That cramped, dark attic becomes a bedroom with real headroom and windows that actually let light in. Maybe it’s a home office where you can close the door and think. Maybe it’s finally giving your teenager their own room so everyone stops stepping on each other.
The difference isn’t subtle. Natural light changes how a space feels. You’re not ducking under rafters or squinting in the dark anymore.
And if you’re thinking about selling down the line, you’re looking at real value here. Research shows a well-done loft conversion can bump your property value by up to 22%. In Garden City Park, where the median home value hit $796,600 last year, that’s not pocket change. But even if you’re staying put, you’re living in a house that finally works the way you need it to.
We’ve been working on Long Island homes since before most contractors in the area were born. Over 50 years of dormer installations, extensions, and renovations across Nassau County. Ray’s on the job site every day, not just when there’s a problem.
You’ll notice the difference in how we communicate. We answer the phone. We respond to texts. If your pipes freeze at 3 AM in the middle of a Long Island winter, we pick up.
Garden City Park homes have character, and most were built when attics were afterthoughts. We’ve worked on enough of them to know what fits the neighborhood and what doesn’t. The goal is making your dormer look like it was always part of the house, not something tacked on last year.
First, we come out and look at your attic. We’re checking roof structure, headroom, and what type of dormer makes sense for your house. Shed dormers give you the most space. Gable dormers match traditional architecture better. We’ll tell you what works and why.
Once you’re ready to move forward, we handle the permits and planning. Then the real work starts. We open up the roof section, frame the dormer structure, and tie it into your existing roofline. Roofing, siding, and windows go in next so everything’s weathertight.
Inside, we finish the space with insulation, drywall, and whatever electrical or HVAC work you need up there. We keep the site clean every day because you’re still living in the house. When we’re done, you’ve got finished square footage that feels like it was always part of your home.
Ready to get started?
You’re getting structural framing that’s built to code and engineered for Long Island weather. That means snow loads, wind ratings, and the kind of construction that passes inspection the first time. Roofing and siding that matches your existing house so the addition blends in.
Windows are part of the package. That’s the whole point of a dormer—bringing light into a space that didn’t have it. We’ll talk through window placement based on how you’re using the room and what makes sense for ventilation.
Inside, you get insulation that actually works, drywall, and finish work. If you’re adding a bathroom up there, we run the plumbing. If you need heating and cooling, we extend your HVAC. In Garden City Park, where property values are high and homeowners expect quality, cutting corners doesn’t make sense. You’re adding to your home’s value and your family’s comfort. We treat it that way.
Dormer costs vary based on size, style, and what you’re finishing inside, but you’re typically looking at $15,000 to $45,000 for most residential projects on Long Island. A small shed dormer that adds headroom and a window runs on the lower end. A full dormer that creates an entire bedroom with a bathroom runs higher.
The biggest cost drivers are size and interior finishes. If you’re just opening up the space for storage or a simple office, that’s one thing. If you’re running plumbing for a bathroom, adding HVAC, and finishing it like a master suite, the number goes up.
We give you a clear estimate upfront. No surprises halfway through the job. And because we’ve been doing this for 50 years, we know how to price it right the first time. You’re not paying for us to figure it out as we go.
Yes, if it’s done right. That’s the difference between a dormer that looks like it belongs and one that looks like an addition. We match your roofline, your siding, your trim details. The goal is making it look original.
Garden City Park has a mix of colonials, capes, and ranch-style homes. Each one has different architectural details that matter. We’re not slapping a generic box on your roof and calling it done. We’re looking at proportions, window styles, and how the dormer sits relative to the rest of the house.
You’ll see the design before we build. We walk you through what it’s going to look like and why we’re recommending a specific dormer style. Most of our clients are surprised at how seamless it looks when it’s finished. That’s the point.
Most dormer projects take four to eight weeks depending on size and scope. A straightforward shed dormer with basic interior finishing runs closer to four weeks. A larger project with a bathroom, custom finishes, or structural complications can push toward eight.
Weather affects the timeline because part of your roof is open during construction. We don’t work in heavy rain or snow. Long Island winters can slow things down, which is why many homeowners schedule dormer work for spring or fall.
We give you a realistic timeline before we start, and we update you if anything changes. You’re not going to call and wonder where we are. Ray’s on site, the crew shows up when they’re supposed to, and we stay on schedule unless there’s a legitimate reason we can’t. You’ll know what’s happening and when.
Yes, dormer additions require permits in Garden City Park and throughout Nassau County. Any structural change to your roof that adds living space needs to be permitted, inspected, and done to code.
We handle the permit process. You’re not filling out paperwork or dealing with the building department. We submit the plans, schedule the inspections, and make sure everything passes. It’s part of the service.
Some contractors will suggest skipping permits to save money or time. That’s a mistake. If you ever sell your house, unpermitted work becomes a problem. Inspectors find it. Buyers walk away. Insurance companies deny claims. It’s not worth the risk, and it’s not how we operate. We pull permits, do the work right, and you get a dormer that’s legal and adds real value to your home.
Yes, and that’s one of the most common reasons homeowners add dormers in Garden City Park. If you’ve only got one bathroom for a multi-bedroom house, or if your kids are sharing a bathroom and it’s causing problems, a dormer with a bathroom solves it.
We run the plumbing up from your existing lines. That includes water supply, drain lines, and venting. If your attic doesn’t have plumbing now, it’s not a dealbreaker. We route it through walls or chases so you don’t see exposed pipes.
The dormer gives you the headroom and floor space you need for a full bathroom. Shower, toilet, vanity, ventilation—it all fits. You’re adding serious functionality to your home, and if you’re thinking about resale value, a second full bathroom is one of the best investments you can make. Buyers on Long Island expect multiple bathrooms, especially in higher-value homes like the ones in Garden City Park.
Only if it’s done poorly. A properly built dormer with the right insulation and windows won’t hurt your energy bills. In fact, it can improve airflow and reduce the load on your HVAC if your attic was a heat trap before.
We insulate to current code minimums or better. That means spray foam or high-R-value batts in the walls and ceiling. Windows are double-pane, low-E glass that keeps heat in during Long Island winters and out during summer. We seal everything tight so you’re not losing conditioned air.
The key is doing it right from the start. Cheap insulation, gaps in the framing, or poorly installed windows will cost you every month on your utility bill. We’ve been doing this long enough to know what works. You’re getting a finished space that’s comfortable year-round without spiking your energy costs.
