Your windows are costing you money every month. In a region where energy costs have jumped 90% year-over-year, drafty windows can add hundreds to your annual utility bills.
Energy-efficient windows change that equation. With proper Low-E coatings and argon gas insulation, you can cut your heating and cooling energy use by up to 40%. That means lower bills, more consistent temperatures, and an end to those cold drafts that make winter miserable.
The right windows also protect your furniture from UV damage and qualify for federal tax credits up to $1,200, plus NYSERDA Comfort Home incentives up to $4,000. You’re not just buying windows—you’re investing in long-term savings and comfort.
We’ve been serving Shelter Island Heights and surrounding Long Island communities for years. We understand what coastal weather does to windows—the humidity, the salt air, the temperature swings from harsh winters to humid summers.
That local knowledge matters when you’re choosing windows that need to perform year-round. We don’t sell you the same windows we’d install in Arizona. We recommend solutions designed for our specific climate zone, with the right U-factors and SHGC ratings to handle Long Island’s weather patterns.
Our installations meet industry standards, and we stand behind our work with comprehensive warranties that protect your investment.
Poor installation kills even the best windows. That’s why we follow manufacturer specifications exactly—it’s the only way to ensure your warranty stays valid and your windows perform as designed.
First, we measure everything twice. Your windows are manufactured to exact specifications, so precision matters from the start. We then carefully remove your old windows, prep the opening, and check for any structural issues that need addressing.
Installation involves proper flashing, insulation, and sealing—the details that prevent air leaks and water damage down the road. We level, square, and secure each window, then apply exterior caulking and interior insulation to eliminate drafts. Finally, we test operation and clean up completely, leaving you with windows that look great and perform even better.

We handle everything from single window replacements to whole-house projects. Whether you need vinyl windows for durability and low maintenance, or you’re looking at energy-efficient options for new construction, we’ve got the expertise to match windows to your specific needs.
Shelter Island Heights homes face unique challenges. The coastal location means windows need to handle salt air, humidity, and temperature extremes. We work with ENERGY STAR certified products that meet the Northern Climate zone requirements—U-values of 0.27 or lower and proper R-factors for maximum insulation.
Our service includes helping you navigate available incentives. Between federal tax credits and New York State programs, there’s significant money available to offset your investment. We’ll walk you through what qualifies and help you maximize your savings while getting windows that truly perform in our local climate.
Window replacement in Long Island typically ranges from $500-600 per window for quality vinyl installations, with wood windows running $800-1,100 per window installed. The total cost depends on window size, style, energy efficiency features, and installation complexity.
For most Shelter Island Heights homes, you’re looking at $4,800-6,000 for 10 standard vinyl windows, or $7,200-9,000 for 15 windows. Custom sizes, bay windows, or specialty shapes will increase costs. The good news is that energy-efficient windows often pay for themselves through lower utility bills, and current tax credits can reduce your upfront investment by up to 30%.
Long Island’s humid subtropical climate with cold winters and hot summers requires windows with specific performance characteristics. You want Low-E coatings to filter UV light, double or triple-pane glass with argon gas insulation, and U-factors of 0.30 or lower for proper thermal resistance.
ENERGY STAR certified windows designed for the Northern Climate zone work best here. They balance heat retention in winter with heat gain control in summer. Vinyl frames perform well in our coastal environment because they don’t rot, warp, or require regular maintenance like wood, and they handle humidity and salt air without deteriorating.
The key is matching window performance to our specific weather patterns, not just buying the cheapest option available.
Professional installation isn’t just recommended—it’s essential for warranty coverage and proper performance. Even the most energy-efficient window won’t save you money if it’s installed incorrectly, and most manufacturers void warranties for improper installation.
Professional installation ensures proper flashing, air sealing, and insulation that prevent drafts and water damage. We have the tools and experience to handle structural issues, ensure windows are level and square, and create the weathertight seal that maximizes energy efficiency. DIY installation might save money upfront, but it often costs more long-term through poor performance and potential damage.
In Long Island’s coastal climate, proper installation is especially critical because of humidity and weather exposure.
Look for ENERGY STAR certification first—it’s your baseline for energy performance. Then focus on specific features: Low-E coatings that filter UV light while maintaining visibility, double or triple-pane glass with argon gas insulation, and U-factors of 0.30 or lower for our climate zone.
NFRC labels provide the performance data you need to compare windows. For Long Island, you want low U-factors for thermal resistance and appropriate SHGC ratings to balance heat gain. Warm-edge spacers reduce condensation, and quality frames (vinyl or fiberglass) provide durability without maintenance.
These features work together to reduce energy costs, eliminate drafts, protect your furniture from UV damage, and maintain comfortable temperatures year-round.
Yes, significant incentives are available right now. Federal tax credits through the Inflation Reduction Act provide up to 30% credit on energy-efficient windows, capped at $1,200. New York State’s NYSERDA Comfort Home program offers additional incentives up to $4,000 for qualifying energy efficiency packages that include ENERGY STAR windows.
These programs have specific requirements—windows must meet ENERGY STAR certification and proper U-factor ratings. The credits reduce your tax liability dollar-for-dollar, making energy-efficient windows more affordable while ensuring you get products that actually perform.
We help you understand which windows qualify and how to claim available incentives to maximize your savings.
Quality vinyl windows with proper installation typically last 20-30 years in Long Island’s coastal climate, while premium fiberglass windows can last 30-40 years. The key factors are material quality, proper installation, and how well the windows handle humidity, salt air, and temperature fluctuations.
Vinyl windows perform exceptionally well here because they don’t rot, warp, or require regular maintenance like wood. They handle coastal conditions without deteriorating, and quality manufacturers back them with lifetime warranties. Wood windows can last just as long but require more maintenance in our humid environment.
Proper installation and quality materials are more important than window type—poorly installed premium windows will fail faster than properly installed standard windows.
