You stop checking the ceiling every time a storm rolls through. No more buckets, no more stains spreading across your drywall, no more wondering if this is the storm that finally causes real damage.
Your home stays dry because the installation is done right the first time. That means proper flashing around the frame, weatherproof seals designed for Long Island’s freeze-thaw cycles, and materials that hold up against salt air and coastal moisture. You’re not patching the same problem in six months.
Your energy bills drop because modern skylights don’t hemorrhage heat like the old ones. You get natural light without paying for it in wasted heating and cooling. And if you’re selling eventually, buyers notice skylights that actually work—it’s one less thing they’ll use to negotiate your price down.
We handle exterior work in Mount Sinai and across Suffolk County—roofs, chimneys, gutters, and skylights that take a beating from nor’easters and hurricanes. We’re licensed, we’re local, and we know what happens to cheap installations after a few Long Island winters.
Mount Sinai gets 27 to 30 inches of snow most years, and January hits hardest. That’s when you find out if your skylight was installed correctly or if someone cut corners. We’ve been cleaning up those mistakes for over two decades.
You’re not getting a crew that learned roofing in Arizona. You’re getting people who understand ice dams, salt corrosion, and what actually holds up when the temperature swings 40 degrees in a weekend.
First, we inspect the skylight and the roof deck around it. Most leaks aren’t just the skylight itself—it’s rotted flashing, damaged shingles, or water that’s been sitting in the wood for months. We tell you what we find, not what we want to sell you.
Then we remove the old skylight carefully. If there’s damage underneath, we repair the deck and surrounding structure before the new unit goes in. Skipping this step is how you end up with a new skylight that still leaks.
Installation means new flashing integrated with your roofing system, proper sealing at every joint, and a skylight rated for weather resistance. We’re usually working with VELUX or comparable brands—units with actual warranties that matter. The interior gets finished so you’re not staring at exposed framing, and we clean up the job site completely before we leave.

You get the full removal of your existing skylight and any damaged materials around it. That includes rotted wood, compromised flashing, and shingles that need replacing to integrate the new installation properly.
The new skylight comes with manufacturer warranties—usually 10 years on labor and up to 30 years on materials depending on the brand. We install weather-resistant flashing systems designed specifically for Long Island’s coastal climate, not generic hardware store kits that fail in two years.
Energy-efficient models reduce your heating and cooling costs, and some qualify for federal tax credits. That’s real money back, not just a feel-good talking point. In Mount Sinai, where salt air accelerates corrosion and humidity degrades seals faster than inland areas, the quality of materials matters more than most contractors want to admit.
We handle the entire job—structural repairs if needed, new skylight installation, interior finishing, and cleanup. You get one crew, one timeline, and one company responsible if anything needs adjustment.
Most residential skylight replacements in Mount Sinai run between $1,500 and $3,500 depending on the size, type of skylight, and what we find when we open up the roof. If there’s structural damage underneath—rotted decking or compromised framing—that adds to the cost because it has to be fixed before the new skylight goes in.
Basic fixed skylights cost less than venting models or larger units. Energy-efficient options with Low-E coatings and better insulation run higher upfront but qualify for federal tax credits and lower your utility bills over time. We give you an honest estimate after inspecting the actual condition of your roof and skylight, not a ballpark number designed to get you on the phone.
Scheduling during late fall or winter sometimes saves 10-15% on labor compared to peak summer months when everyone wants roof work done. But if your skylight is actively leaking, waiting to save a few hundred dollars while water damages your ceiling and insulation is a bad trade.
Most skylight leaks come from failed flashing, not the skylight itself. Flashing is the metal barrier between your skylight and the roof that keeps water out. When it’s installed wrong, corrodes from salt air, or separates from the roof deck during freeze-thaw cycles, water finds a way in.
Ice dams are another major cause in Mount Sinai. When heat escapes through your attic, it melts snow on the roof. That water runs down, hits the cold edge near your skylight, refreezes, and creates a dam that forces water under the flashing and into your house. Poor attic insulation makes this worse.
Sometimes the skylight seal itself degrades—especially on older plastic units that weren’t designed for coastal weather. Long Island’s humidity, temperature swings, and salt air break down cheaper materials faster than they would inland. If your skylight is over 15 years old and leaking, replacement usually makes more sense than trying to patch it again.
Most skylight replacements take one to two days depending on the size, roof access, and whether we’re fixing structural damage underneath. A straightforward swap on an accessible roof with no hidden problems usually wraps up in a day.
If we find rotted decking, damaged rafters, or extensive water damage once we remove the old skylight, that adds time. We’re not leaving until it’s done right, which sometimes means an extra day to replace compromised wood and let new flashing integrate properly with your roofing system.
Weather matters too. We don’t install skylights in heavy rain or snow because the roof opening needs to stay dry during installation. If the forecast looks bad, we’ll reschedule rather than rush a job that could leak later. You’ve already dealt with one leaking skylight—there’s no point creating another one by cutting corners on installation day.
Yes, if you’re replacing an old single-pane or plastic skylight with a modern energy-efficient model. Older skylights lose heat in winter and let in excessive heat during summer, which forces your HVAC system to work harder. Energy Star-rated skylights with Low-E coatings and insulated frames can cut that energy loss significantly.
Natural light from a properly installed skylight also reduces your need for artificial lighting during the day. That’s a smaller impact than heating and cooling savings, but it adds up over time. Some homeowners see utility bill reductions of 10-12% after upgrading to energy-efficient skylights, though your actual savings depend on your home’s insulation, HVAC efficiency, and how much direct sunlight the skylight receives.
Federal tax credits are available for qualifying energy-efficient skylights, which helps offset the upfront cost. The credit covers a percentage of the installation cost, and your tax preparer can tell you exactly what you’re eligible for based on the specific model we install.
We primarily install VELUX skylights because they hold up in coastal climates and come with legitimate warranties. VELUX has been making roof windows and skylights for over 80 years, and their products are designed for weather resistance—which matters in Mount Sinai where salt air, freeze-thaw cycles, and coastal storms test every exterior component on your house.
We’ll also work with other quality manufacturers depending on your specific needs and budget. What we won’t do is install cheap big-box store skylights that leak in three years. The skylight itself is only part of the equation—installation quality matters just as much, and we’re not putting our reputation behind products we know won’t last.
If you have a preference for a specific brand or model, we’ll tell you honestly whether it’s appropriate for Long Island’s climate. Some skylights are designed for mild weather and fail quickly here. Others are overbuilt for what you actually need. We’ll recommend what makes sense for your roof, your budget, and how long you plan to own the house.
Yes. If your skylight is actively leaking and causing damage, we can respond quickly to stop the immediate problem. That usually means temporary weatherproofing—tarping the exterior, containing interior water damage, and stabilizing the situation until we can schedule a proper repair or replacement.
Emergency repairs aren’t permanent fixes. They’re meant to prevent further damage to your ceiling, insulation, and interior until we can address the root cause. If your skylight is old, badly installed, or structurally compromised, a temporary patch just buys you time—you’ll still need replacement to solve the problem permanently.
We’re available for storm damage response after hurricanes and nor’easters when skylights get damaged by falling branches, flying debris, or extreme wind. Suffolk County takes a beating during major storms, and skylight damage is common. Call us as soon as it’s safe to do so, and we’ll get someone out to assess the damage and prevent water from destroying your home’s interior.
