Your skylight stops leaking. That’s the baseline, not a bonus.
Beyond that, you’re looking at real energy savings—Velux skylights run up to 35% more efficiently than older plastic units, which translates to $10-15 less on your electric bill every month. Over a properly installed skylight’s 20-30 year lifespan, that’s thousands of dollars staying in your account instead of going to the utility company. You also get up to five times more natural light than a standard window, which matters more than you think during Suffolk County’s gray winters when shorter days and cloud cover already drag on your mood.
The installation itself includes proper flashing, waterproof sealing, and materials designed to handle what Holbrook throws at them—freeze-thaw cycles, nor’easters, coastal humidity, and rapid temperature swings. If your current skylight is over 15 years old, the seals, hardware, and flashing are likely degraded enough that replacement makes more sense than patching. Most single skylight replacements take four to six hours and get completed in one day, weather permitting.
You’re not just fixing a problem. You’re upgrading to technology that didn’t exist when your old skylight went in—better insulation, rain sensors, solar-powered options, and manufacturer warranties that cover materials for up to 10 years.
We’ve spent more than 10 years handling skylight replacement, roof work, and exterior projects across Suffolk County. We’re licensed, insured, and we know how Holbrook’s climate beats up on homes—especially skylights.
Most skylight leaks don’t come from the skylight itself. They come from improper flashing or degraded sealants that couldn’t handle the freeze-thaw cycles we get here. Water seeps into small gaps, freezes overnight, expands, and turns minor issues into major leaks. We’ve seen it hundreds of times, and we know how to prevent it.
We don’t upsell. We assess what’s actually wrong, recommend the most cost-effective fix that solves the problem long-term, and give you upfront pricing with no hidden fees. If your skylight needs replacing, we’ll tell you why. If it just needs better flashing, we’ll tell you that too.
First, we come out and inspect your current skylight. We’re looking at the unit itself, the flashing, the surrounding roof membrane, and any signs of water damage or improper installation. Most skylight problems show up in predictable places if you know what to look for.
Once we know what’s going on, we walk you through your options. If replacement makes sense, we’ll recommend the right Velux unit for your space and explain what the installation includes—new flashing, updated sealing, and any roof membrane upgrades needed to make sure the entire system works together. You’ll get a clear price before any work starts.
On installation day, we remove the old skylight, prep the opening, install the new Velux unit with professional-grade flashing materials, and seal everything to handle Suffolk County weather. We clean up completely when we’re done. Most jobs finish in four to six hours unless we’re dealing with structural repairs or multiple units.
After installation, you get our workmanship warranty plus Velux’s manufacturer warranty on materials. If the skylight leaks due to our installation within the warranty period, we fix it at no charge. That’s the standard, not a special offer.

Every skylight replacement we do in Holbrook includes the Velux skylight unit, professional-grade flashing designed for Long Island weather, waterproof sealing around the entire installation, and a full cleanup when the job’s done. If the surrounding roof membrane needs updating, we handle that too—because a new skylight on a failing roof system just moves the problem around.
We work with modern Velux units that offer features older skylights can’t match. Better insulation values, ENERGY STAR certification that can reduce your heating and cooling costs by up to 13%, and options like rain sensors or solar-powered operation if you want them. These aren’t the single-pane, poorly sealed units from 20 years ago that turned rooms into saunas in summer and ice boxes in winter.
Suffolk County homes deal with specific challenges—freeze-thaw cycles that crack sealants, coastal salt air that corrodes hardware, and temperature swings that stress materials. We use flashing and sealing products designed for this climate, not generic solutions that fail in three years. The goal is an installation that lasts decades, not one that needs repairs every few seasons.
You also get transparent pricing up front. Skylight replacement in 2025 typically runs between $2,000 and $5,300 depending on the unit size, roof access, and whether structural repairs are needed. We’ll tell you exactly where your project falls in that range before we start.
If your skylight is over 15 years old, replacement usually makes more sense than repair. The seals, hardware, and flashing degrade over time, and patching one problem often just buys you a year or two before something else fails.
Leaking is the most common sign, but it’s not always obvious. Sometimes you’ll see water stains on the ceiling around the skylight. Other times the leak shows up a few feet away because water travels along roof decking before it drips through. Fogging between panes means the seal has failed and moisture is getting inside the unit—that’s not fixable.
If you’re seeing condensation on the inside of the glass during winter, that’s usually an insulation problem. Older single-pane or poorly sealed skylights let warm interior air hit cold glass, which creates condensation and can lead to mold or wood rot in the framing. Energy bills that spike in summer or winter can also point to skylight inefficiency, especially if the room with the skylight is noticeably hotter or colder than the rest of the house. We can assess what’s actually wrong during a free inspection and tell you whether repair or replacement makes sense for your situation.
Skylight replacement in Holbrook typically runs between $2,000 and $5,300 in 2025, depending on the size of the unit, roof access, and whether any structural repairs are needed. That price includes the Velux skylight, professional installation, proper flashing, waterproof sealing, and cleanup.
Smaller fixed skylights on accessible roofs fall toward the lower end. Larger venting units, skylights on steep or high roofs, or jobs that require repairing damaged roof decking or framing cost more. If your roof membrane around the skylight is degraded, we’ll factor in the cost to upgrade that too—because installing a new skylight on a failing roof system just moves the problem.
Most homeowners don’t realize that skylight problems often get worse quickly in Suffolk County’s climate. What starts as a small leak can become structural damage, mold issues, and expensive interior repairs if not addressed properly. The cost of replacement is almost always less than the cost of fixing water damage to ceilings, walls, insulation, and framing. We offer financing options for qualified homeowners, and we’ll give you upfront pricing with no hidden fees before any work starts.
Yes, if you’re replacing an older skylight with a modern ENERGY STAR certified unit. Velux skylights can be up to 35% more energy efficient than older plastic skylights, which can save you $10-15 per month on electricity with proper sizing, placement, and professional installation.
ENERGY STAR certified skylights reduce heating and cooling costs by an average of up to 13%, which adds up over time. If your current skylight is driving up your bills by $200-300 annually, a replacement that costs $1,500-2,500 installed pays for itself in energy savings over eight to ten years—while also eliminating leak risks and improving home comfort and value.
Older skylights, especially single-pane units or those with broken seals, are terrible for energy efficiency. They let heat escape in winter and turn rooms into greenhouses in summer. Modern Velux units use low-E coatings, argon gas fills, and better sealing to keep conditioned air inside where it belongs. The difference is noticeable within the first month, especially in rooms that used to be uncomfortably hot or cold. Over the 20-30 year lifespan of a properly installed skylight, those monthly savings add up to thousands of dollars.
Most single skylight replacements take four to six hours and get completed in one day, weather permitting. If we’re replacing multiple skylights or dealing with structural repairs to damaged roof decking or framing, the job might take longer.
The process moves quickly because we’re working with a pre-existing opening. We remove the old skylight, inspect and prep the framing, install the new Velux unit with proper flashing, seal everything, and clean up completely. The most time-consuming part is usually the flashing and sealing work, which is also the most important—that’s what keeps water out for the next 20-30 years.
Weather can delay things. We won’t install a skylight in rain or snow because we need dry conditions to properly seal the flashing and roof membrane. If the forecast looks questionable, we’ll reschedule rather than rush a job that could leak later. Suffolk County’s freeze-thaw cycles and coastal weather mean timing matters. Most homeowners schedule skylight replacement in late spring, summer, or early fall when conditions are more predictable and we can guarantee a weather-tight installation.
Velux skylights cost more upfront, but they’re built to last decades in climates like Suffolk County’s. Cheaper brands often use thinner materials, lower-quality seals, and hardware that corrodes or fails within a few years—especially in coastal areas with salt air and freeze-thaw cycles.
Velux units come with better insulation values, ENERGY STAR certification, and warranties that actually mean something—up to 10 years on materials. The flashing kits are designed to integrate with your roof system properly, which is critical for preventing leaks. Cheaper brands often use generic flashing that doesn’t account for different roof pitches, materials, or weather conditions, and that’s where most leaks start.
We’ve replaced plenty of budget skylights that failed within five to seven years. The homeowner saved a few hundred dollars on the initial install, then spent thousands fixing water damage and replacing the unit again. Velux skylights installed correctly can last 20-30 years without major issues. The frames don’t warp, the seals don’t fail prematurely, and the hardware holds up to Long Island weather. If you’re planning to stay in your home for more than a few years, Velux is the smarter investment. If you’re flipping a property or just need something temporary, cheaper options exist—but we’ll be honest about what you’re getting.
Yes. Every skylight installation we do in Holbrook comes with a comprehensive leak-free guarantee backed by our workmanship warranty and Velux’s manufacturer warranty. Our workmanship warranty covers the installation itself—if the skylight leaks due to improper flashing, sealing, or installation within the warranty period, we fix it at no charge.
Velux covers the skylight materials for up to 10 years depending on the model. That includes the frame, glazing, seals, and hardware. If a component fails due to a manufacturing defect, Velux replaces it. Between our installation warranty and Velux’s product warranty, you’re covered from every angle.
The key is working with contractors who understand Suffolk County’s freeze-thaw cycles, coastal salt air, and temperature extremes—and who use quality materials designed for this climate. We’ve been doing this for over 10 years, and we stand behind our work. If something goes wrong that’s our fault, we make it right. That’s not a marketing line. That’s how we’ve stayed in business and built a reputation in Suffolk County for honest pricing and reliable service.
