No more water stains spreading across your ceiling every time it rains. No more watching the forecast and wondering if this storm will be the one that finally does serious damage.
Your energy bills drop because modern double-pane glass actually insulates instead of letting heat pour out in winter and flood in during summer. You get clear, bright natural light again—not that foggy, yellowed haze you’ve been living with.
The skylight stops being a problem you think about. It just works. When storms roll through Islip, you don’t worry about it. When temperatures swing from freezing to 80 degrees in the same week, the seals hold. That’s what proper residential skylight replacement does—it removes the problem entirely.
We’ve spent more than 10 years working on homes throughout Islip and Suffolk County. We’re licensed, we don’t use subcontractors, and every person on our crew is trained to our standards.
We’ve seen what Long Island’s coastal humidity does to skylights. We know how freeze-thaw cycles crack seals that looked fine in September. We’ve replaced enough failed installations to know exactly what not to do—and what actually lasts.
You’re not getting a crew that learned skylight installation from YouTube. You’re getting professionals who’ve done this hundreds of times in the exact climate conditions your home faces.
We start with an honest assessment of your current skylight. Sometimes you actually need replacement. Sometimes a repair handles it. We tell you which one applies to your situation and why.
If replacement makes sense, we remove your old skylight and inspect the roof opening for any hidden damage—rot, compromised decking, anything that would cause problems later. We handle those issues before the new skylight goes in, not after.
Then we install your new skylight with proper flashing that integrates with your roof system. We use weather-resistant materials designed for Suffolk County conditions. Every seal gets done right because that’s where most installations fail.
Most single skylight replacements take four to six hours. You’re typically looking at one day of work, weather permitting. We clean up completely when we’re done—no debris left in your yard or driveway.

You get premium Velux skylights engineered specifically for climates like ours. These aren’t builder-grade units that’ll fail in five years. They come with integrated flashing systems, double-pane insulated glass, and manufacturer warranties up to 10 years on materials.
Our installation includes a 10-year workmanship warranty. If water gets in because of how we installed it, we fix it. No arguments, no fine print loopholes.
Islip’s weather is particularly brutal on skylights. You get freeze-thaw cycles that expand and contract materials. You get coastal humidity that accelerates degradation. You get storms that test every seal. We account for all of it during installation because we’ve been doing this here long enough to know what fails and what holds up.
If you want upgraded features—solar-powered models that open for ventilation and close automatically when it rains—we install those too. But the standard installations are already built to handle decades of Long Island weather without problems.
Most skylight replacements in Islip run between $800 and $2,500 per skylight, including installation. That’s not a vague estimate—it’s based on actual jobs we’ve completed throughout Suffolk County.
The range depends on skylight size, type, and roof complexity. A standard fixed skylight on an accessible roof costs less than a large vented model on a steep pitch. If we find roof damage during removal, that adds to the cost, but we tell you about it before proceeding.
You get upfront pricing before work starts. No hidden fees, no surprise charges when the job’s done. We break down exactly what you’re paying for—materials, labor, warranty coverage—so you know where your money goes.
A single skylight replacement typically takes four to six hours from start to finish. Most jobs get completed in one day, assuming weather cooperates.
Multiple skylights obviously take longer. Three skylights might be a full day or stretch into two, depending on roof access and whether we encounter any underlying damage that needs addressing.
Weather delays happen. We’re not installing skylights in heavy rain or high winds because that’s how you end up with water damage and improper sealing. If conditions aren’t right, we reschedule. You’d rather have it done correctly than done fast.
If the skylight itself is still in good shape and the leak is coming from damaged flashing or a failed seal, repair usually makes sense. You’re looking at a fraction of replacement cost—often one-third to one-quarter the price.
But if the glass is fogged, cracked, or yellowed, or if the frame is warped or rotted, replacement is the smarter move. Repairs won’t fix those issues, and you’ll just be throwing money at a skylight that’s going to fail anyway.
We’ve seen plenty of homeowners get quoted for full replacement when they only needed repairs. We’ve also seen people waste money on repairs for skylights that were already done. We’ll tell you honestly which situation applies to your skylight and explain why.
Velux skylights come with manufacturer warranties up to 10 years on materials. That covers defects in the skylight itself—glass, frame, operating mechanisms.
Our installation carries a separate 10-year workmanship warranty. If water gets in because of how we installed it, we come back and fix it at no cost to you. That covers flashing failures, seal issues, anything related to the installation work.
Both warranties matter. A great skylight installed poorly will leak. A mediocre skylight installed correctly will still fail early. You need both components done right, and you need both warranties backing up the work.
Double-pane insulated glass is non-negotiable for Long Island. Single-pane skylights can’t handle the temperature swings we get here—freezing winters, hot humid summers, 40-degree shifts in a single day during spring and fall.
Velux skylights are specifically engineered for climates like ours. Their flashing systems integrate properly with various roof types, and their seals hold up to freeze-thaw cycles that destroy cheaper brands.
Fixed skylights are the most weather-resistant option because there are no moving parts to fail. Vented skylights work fine if installed correctly, but they have more potential leak points. Solar-powered vented models are popular because they close automatically when it rains—you don’t have to worry about forgetting to close them before a storm.
Modern double-pane skylights with Low-E coatings reduce heat transfer significantly compared to old single-pane units. You lose less heat in winter and gain less heat in summer.
The energy savings depend on how bad your current skylight is. If you’re replacing a 20-year-old single-pane skylight that leaks air, you’ll notice a real difference in how hard your HVAC system works. If your current skylight is only five years old and already has decent insulation, the improvement will be smaller.
Proper installation matters as much as the skylight itself. The best insulated skylight in the world still bleeds energy if it’s not sealed correctly. That’s why we focus on flashing and weatherproofing—because that’s where most energy loss actually happens.
