You’ve probably walked past that attic door a hundred times. Dark, cramped, full of boxes you haven’t touched in years. A dormer changes that completely.
It brings in natural light through new windows. It adds headroom so you can actually stand up. And it transforms dead space into a bedroom, office, or studio you’ll actually use.
On Long Island, lot sizes don’t give you room to build out. Zoning rules make it even harder. Dormers solve that by adding square footage vertically. You get the space you need without dealing with variances, setbacks, or losing your backyard.
The value shows up fast. Homes with dormer additions sell quicker and for more money. You’re not just adding space—you’re making your home more functional and more valuable at the same time.
We’ve been working in Hicksville and across Nassau County for over 40 years. We’ve built dormers, remodeled kitchens, finished basements, and handled first-floor renovations for homeowners who needed more space but didn’t want to move.
We answer the phone. We respond to texts. If something goes wrong—frozen pipes, emergency repairs—we show up. Our crews keep job sites clean, and we handle permits and inspections so you don’t have to figure it out yourself.
Hicksville homes are older. Many were built 50 or 60 years ago, and they weren’t designed for how people live now. We understand what it takes to update them the right way, and we’ve done it enough times to know what works and what doesn’t.
First, we come out and look at your attic. We measure the space, check the roof structure, and talk through what you’re trying to accomplish. Some homes can handle a full shed dormer. Others work better with gable dormers or a smaller design.
Once we know what fits, we pull permits. That’s on us. We handle the paperwork, the inspections, and the code requirements so you’re not stuck dealing with the town.
Construction starts with opening up the roof. We frame the dormer, install windows, and tie everything into your existing roofline. Then we finish the interior—insulation, drywall, flooring, whatever the space needs to be livable. If you’re adding a bedroom, we make sure it meets egress codes. If it’s an office, we run electric where you need it.
The timeline depends on the size of the dormer and the scope of the interior work. Smaller projects take a few weeks. Larger ones take longer. We’ll give you a realistic schedule upfront so you know what to expect.
Ready to get started?
Every dormer job is different, but the core work stays the same. We handle structural framing, roofing, siding to match your home, and window installation. Interior finishes depend on how you plan to use the space—drywall, paint, flooring, trim, and electrical are all part of it.
In Hicksville, a lot of homes have Cape Cod or Colonial-style rooflines. Those work well for dormers because there’s already attic space to expand into. We’ve done shed dormers that span most of the roof, and we’ve done smaller gable dormers that add just enough room for a closet or a desk.
If your roof is older, we’ll let you know. Sometimes it makes sense to replace the whole roof at the same time as the dormer. You’re already opening it up, so the timing works. Other times, the roof is fine and we just tie the new work into what’s there.
Long Island winters are tough on roofs. Ice dams, wind, snow load—it all matters. We build dormers that hold up to the weather and don’t create leaks or drafts down the road. That means proper flashing, insulation, and ventilation from the start.
Small dormers start around $2,500 to $6,300 depending on size and complexity. Larger shed dormers that add a full bedroom or more can run significantly higher, especially when you factor in interior finishes like flooring, electrical, and HVAC.
The cost depends on what you’re building and what’s already there. If your attic has good bones—solid framing, decent headroom—it’s less work. If we need to reinforce joists or reroute ductwork, that adds to it.
We’ll give you a clear estimate after we see the space. No surprises, no upselling. Just an honest number based on what the job actually requires.
Yes. Any structural work that changes your roofline or adds living space requires a building permit in Nassau County. That includes dormers.
We handle the permit process. We submit the plans, coordinate inspections, and make sure everything meets code. You don’t need to go to the town building department or figure out what forms to fill out.
Skipping permits is a bad idea. It can hold up a future home sale, and it leaves you liable if something goes wrong. We do it right the first time so you don’t have issues later.
Yes. Dormer additions typically return 60% to 80% of the cost when you sell, and homes with extra living space sell faster. If you’re adding a bedroom, the value bump is even higher—bedroom additions increase home value by an average of $40,000 on Long Island.
Buyers want move-in-ready homes with space. A finished dormer checks both boxes. It also improves curb appeal, especially if the dormer is designed to match your home’s style.
Even if you’re not selling anytime soon, the added space makes your home more livable. That’s value you get to enjoy now, not just when you list the house.
A small dormer can take two to four weeks. Larger projects—especially ones that involve finishing a full bedroom or bathroom—can take six to eight weeks or more.
Weather affects the timeline. We can’t frame a dormer in the middle of a rainstorm, and Long Island winters slow things down. We’ll give you a realistic schedule based on the time of year and the scope of work.
We also keep the job site clean and the work moving. No disappearing for days at a time, no dragging things out. You’ll know what’s happening and when.
Yes. We match siding, roofing, and trim so the dormer looks like it was always part of the house. That’s especially important in Hicksville, where a lot of homes have specific architectural styles.
If your home has vinyl siding, we source the same color and profile. If it’s wood shakes or brick, we match that too. Same goes for shingles—we make sure the new roof blends with the old one.
A poorly matched dormer stands out and hurts resale value. We take the time to get it right so the addition looks intentional, not tacked on.
A shed dormer runs along the length of your roof and creates a lot of interior space. It’s the best option if you’re adding a full bedroom, bathroom, or large office. The roofline slopes gently from front to back, giving you maximum headroom.
A gable dormer is smaller and projects out from the roof. It adds light and some extra space, but not as much as a shed dormer. Gable dormers work well if you just need a window, a small reading nook, or a closet.
Which one makes sense depends on your goals and your home’s structure. We’ll walk you through both options and show you what fits your space and budget.
