Mastic Skylight Replacement Experts

We Know Long Island Skylights

We’ve been handling skylight replacement in Mastic and throughout Long Island for over 15 years. We’ve seen every type of skylight problem you can imagine—from 1970s installations that were never sealed properly to newer skylights that failed because corners were cut during installation. We’re not the cheapest option, and that’s intentional. When you’re cutting a hole in your roof, you want contractors who understand flashing, who know how Long Island weather affects different skylight materials, and who won’t disappear when problems arise. Our customers in Mastic choose us because we show up when we say we will, we explain what we’re doing and why, and we stand behind our work.

Skylight Replacement Process Mastic

Here's Exactly What Happens

First, we inspect your current skylight and the surrounding roof area. We’re looking for the source of leaks, checking flashing condition, and assessing whether the opening itself is properly sized and positioned. Next, we carefully remove the old skylight, making sure to protect your interior from debris and weather. We examine the roof opening, replace any damaged decking, and install new flashing that’s designed to work with your specific roof type. Then we install your new skylight—whether it’s a Velux replacement or another quality brand that fits your needs and budget. We seal everything properly, test for leaks, and clean up completely. You’re left with a skylight that works the way it should, backed by our warranty.

Velux Skylight Replacement Mastic

What You Actually Get

Every skylight replacement includes proper flashing installation, quality sealants that can handle Long Island’s weather extremes, and interior finishing work to match your existing ceiling. We use Velux skylights for most installations because they’re engineered to last and come with solid warranties. In Mastic, we see a lot of homes built in the 70s and 80s with original skylights that are finally failing. The good news is that newer skylights are dramatically more energy efficient. Many of our customers notice lower heating and cooling costs almost immediately. We also handle the permits when required and coordinate with your other contractors if you’re doing broader roof work. The goal is a skylight replacement that solves your current problems and prevents new ones.

How much does skylight replacement cost in Mastic NY?

Skylight replacement in Mastic typically costs between $2,500 and $6,000, depending on the size, type, and complexity of the installation. A basic fixed skylight replacement on a standard asphalt shingle roof costs less than a large vented skylight on a steep or tile roof. The price includes removing your old skylight, any necessary roof repairs, new flashing, the skylight unit itself, and interior finishing work. We provide detailed written estimates so you know exactly what’s included before we start work. Keep in mind that proper skylight replacement is an investment in preventing much more expensive water damage down the road.

How long does a skylight replacement take?

Most skylight replacements take one full day, weather permitting. Simple replacements where we’re installing the same size skylight in an existing opening can sometimes be completed in a few hours. More complex jobs—like replacing multiple skylights, dealing with roof damage, or installing a different size skylight—might take two days. We always protect your interior with tarps and work efficiently to minimize disruption to your daily routine. We schedule skylight work during dry weather whenever possible and can provide temporary weatherproofing if unexpected weather moves in during the project.

What are signs my skylight needs replacement?

The most obvious sign is water leaking around or through the skylight during rain. But you should also consider replacement if you notice condensation between glass panes, drafts near the skylight, or visible cracks in the glass or frame. Staining on your ceiling or walls near the skylight often indicates ongoing water infiltration, even if you don’t see active dripping. Energy bills that seem higher than they should be can also point to skylight problems—old or damaged skylights are major sources of heat loss. If your skylight is more than 20 years old and showing any of these signs, replacement is usually more cost-effective than repeated repairs.

Do you install Velux skylights in Mastic?

Yes, we’re experienced Velux installers and recommend them for most skylight replacements in Mastic. Velux skylights are engineered for durability and energy efficiency, with features like advanced flashing systems and high-performance glass that handles Long Island’s weather extremes. Velux also offers excellent warranties and has a wide range of sizes and styles to fit different home designs. Their fixed, vented, and solar-powered options give you flexibility in choosing features that match your needs and budget. We can also install other quality skylight brands if you have specific requirements or preferences, but Velux consistently delivers the best combination of performance and value for Long Island homes.

Can you fix a leaking skylight or does it need replacement?

It depends on the age of the skylight and the source of the leak. Sometimes leaks can be fixed by replacing flashing, resealing joints, or making minor repairs to the skylight frame or glass. However, if the skylight is more than 15-20 years old, if there’s damage to the glass or frame, or if we find multiple problem areas, replacement is usually the better choice. Older skylights often have outdated sealing systems that will continue to cause problems even after repairs. We’ll always give you an honest assessment during our inspection. If a repair will solve your problem long-term, we’ll recommend that. If replacement makes more sense, we’ll explain why and show you your options.

Do you handle permits for skylight replacement in Mastic?

Most skylight replacements in Mastic don’t require permits if we’re installing the same size skylight in the existing opening. However, if we’re enlarging the opening, changing the skylight type significantly, or doing structural work, permits may be required. We handle all permit applications when they’re needed and make sure the work meets local building codes. We’re familiar with Suffolk County requirements and have good relationships with local building departments. During our initial consultation, we’ll let you know if permits are required for your specific project and include any permit fees in our written estimate. You won’t have any surprises or additional paperwork to deal with.
