Here's Exactly How We Replace Your Skylight

First, we completely remove your old skylight and assess the roof opening for any damage or rot. No shortcuts – if there’s a problem, we fix it properly before moving forward.

Next comes the critical part: proper flashing installation. We use integrated flashing systems with multiple waterproof barriers, not the basic step flashing that fails in Suffolk County’s weather. Every seal gets high-grade materials designed for our freeze-thaw cycles.

Then we mount your new Velux skylight with waterproof sealing around the entire perimeter. We protect your home’s interior with tarps throughout the process and typically complete single skylight replacements in 4-6 hours. Most jobs finish in one day, weather permitting.

How much does skylight replacement cost in Mount Sinai, NY?

Skylight replacement costs in Mount Sinai typically range from $800 to $2,500 per skylight including professional installation. The final price depends on skylight size, type, and roof complexity.

Velux skylights with professional installation usually cost 3-4 times the price of the unit alone, but this includes proper flashing, waterproofing, and our leak-free guarantee.

Yes, modern skylights can significantly reduce energy costs when properly installed. Energy-efficient Velux skylights with Low-E glass and proper insulation reduce artificial lighting needs during the day and provide passive solar heating in winter.

Velux skylights can be up to 35% more energy efficient than older plastic skylights, potentially saving $10-15 monthly on electricity. The key is proper sizing, placement, and professional installation to maximize benefits while preventing heat loss. Over time, these savings help offset the initial investment.

It depends on your skylight’s age and condition. If the frame is structurally sound and the flashing isn’t compromised, glass replacement might be possible for newer units.

However, most skylights over 15 years old benefit from complete replacement because the seals, hardware, and flashing typically need updating too. We’ll assess your specific situation during our free inspection and recommend the most cost-effective solution that actually solves the problem long-term. Sometimes trying to save money with partial repairs ends up costing more when the remaining components fail.

Most skylight leaks happen because of improper flashing installation or degraded sealants, not the skylight itself. In Suffolk County’s freeze-thaw cycles, water gets into small gaps, freezes, expands, and creates larger openings.

We prevent leaks by using integrated flashing systems, multiple waterproof barriers, and proper installation techniques. Our installations include step flashing around the sides and continuous flashing at the head and sill, all sealed with high-grade materials designed for Long Island weather. This comprehensive approach addresses both the skylight unit and its integration with the roof system.

Most single skylight replacements take 4-6 hours, depending on roof type and access. We typically complete the work in one day, weather permitting. Flat roof installations may take longer due to additional waterproofing steps.

We always protect your home’s interior with tarps and work efficiently to minimize disruption. If weather delays the project, we’ll secure the opening completely until we can finish the installation safely. Our goal is to get your home weather-tight as quickly as possible while ensuring quality work.

We provide a comprehensive leak-free guarantee on all skylight installations, backed by our workmanship warranty and the manufacturer’s product warranty. Velux skylights come with up to 10 years on materials and we warranty our installation work.

If your skylight leaks due to our installation within the warranty period, we’ll fix it at no charge. We’ve been serving Suffolk County for over 10 years and stand behind every job we complete. This isn’t just a promise – it’s how we’ve built our reputation in Mount Sinai and throughout Suffolk County.
