Your energy bills don’t lie. If they’re climbing without explanation, your windows are forcing your HVAC system to work overtime—and you’re paying for it every month.
Quality window installation changes that equation fast. New energy-efficient windows with double or triple-pane glass, Low-E coatings, and proper sealing can cut your heating and cooling costs by 25-30%. You’ll feel the difference immediately—no more drafts, cold spots, or rooms that won’t stay comfortable.
Beyond monthly savings, you’re protecting furniture from UV damage and reducing your carbon footprint by hundreds of pounds annually. These aren’t just windows. They’re an investment that pays you back for decades.
We’ve served Long Island homeowners for over two decades at Expressway Roofing and Chimney Inc. We’re fully licensed, bonded, and insured—not because we have to be, but because your peace of mind matters.
As a family-owned business in Suffolk County, we understand Long Island’s climate challenges. Harsh winter winds, humid summers, coastal storms—we know exactly what your windows face and how they need to perform.
Our reputation lives in our work. Quality installations, fair pricing, and showing up when we say we will. No surprises, no runarounds. Just professional service from people who live and work in your community.
We start with a complete assessment of your current windows and your home’s specific needs. No cookie-cutter recommendations—every home is different, and your solution should be too.
Our team takes precise measurements and explains your options clearly. Frame materials, glass packages, energy ratings—you’ll understand what each choice means for your bills, maintenance, and long-term performance. No confusing jargon or pressure tactics.
Installation day runs smoothly because we’ve done the prep work. Our experienced crew protects your home, works efficiently, and cleans up completely. Each window gets properly sealed, insulated, and tested. We don’t consider the job finished until you’re completely satisfied.

Our window installation covers everything from single replacements to whole-house upgrades. We work with energy-efficient vinyl, wood, and composite frames—all designed to meet Long Island’s Northern Climate requirements for maximum performance.
Every installation includes proper insulation, weatherproofing, and sealing to prevent drafts and moisture problems. We use materials built for Islip’s coastal conditions: salt air, temperature swings, and high humidity levels that challenge inferior products.
Long Island homeowners face unique challenges that generic solutions don’t address. Our installations use windows rated specifically for our climate zone, professional-grade techniques, and warranties that protect your investment. You’re getting a complete solution designed for exactly where you live.
Window installation in Islip typically runs $225 to $425 per window, depending on size, style, and energy features. Single replacements might cost less, while whole-house projects often qualify for volume pricing that brings the per-window cost down.
Total investment depends on frame material, glass packages, and any structural work needed. Energy-efficient options with Low-E coatings cost more upfront but save money long-term through lower energy bills—often paying for themselves over time.
We provide detailed written estimates that break down all costs. No hidden fees or surprise charges. Many homeowners find that federal tax credits and utility rebates help offset the initial cost, making energy-efficient windows more affordable than expected.
Islip’s Long Island location means your windows battle harsh winters, humid summers, and coastal storms. Double or triple-pane windows with Low-E coatings perform best in our Northern Climate zone, where ENERGY STAR requires specific efficiency ratings.
Vinyl frames excel in our conditions—they resist moisture damage and don’t expand and contract like other materials. Gas-filled spaces between panes provide extra insulation against temperature extremes that hit Long Island throughout the year.
For homes near the water, corrosion-resistant hardware is essential. We install windows that meet ENERGY STAR requirements for our region: U-Value of 0.27 or lower and R-Factor between 13-21. These specifications ensure optimal performance in Long Island’s specific climate challenges.
Individual window installation takes 30-60 minutes per window once we’re on-site. A typical whole-house project with 10-15 windows usually completes in one to two days, depending on complexity and any custom work required.
The complete timeline from order to installation typically runs 4-6 weeks. This includes consultation, final measurements, custom window manufacturing, and installation scheduling. We’ll provide a specific timeline with your estimate so you can plan accordingly.
Weather affects scheduling, especially during Long Island winters. We plan installations during favorable conditions to ensure proper sealing and curing of materials. If weather forces rescheduling, we’ll notify you promptly and prioritize getting your project back on track.
Most window replacements in Islip don’t require permits when you’re replacing existing windows with similar sizes and styles. However, changing window sizes, adding new openings, or making structural modifications typically require permits and inspections.
We handle permit applications when needed and ensure all work meets local building codes. Our experience with Islip’s requirements means we know exactly what’s needed for your project and can guide you through the process without delays.
For new construction or major renovations, permits are always required. We coordinate directly with local inspectors and handle required inspections. This ensures your installation is completely compliant and protects your investment and insurance coverage.
We provide comprehensive warranties covering both installation workmanship and window products. Our installation warranty covers workmanship issues like improper sealing, alignment problems, or installation defects for years after completion.
Window manufacturers offer separate product warranties—typically 10-20 years on frames and hardware, with glass warranties varying by product line. We help you understand exactly what’s covered and handle warranty claims if issues develop.
Professional installation protects your warranty coverage. DIY installations often void manufacturer warranties, leaving you without protection if problems arise. Our licensed, insured installation ensures full warranty protection and gives you a local contact if anything needs attention.
Rising energy bills without obvious cause often indicate window efficiency problems—especially if your HVAC runs constantly but rooms stay uncomfortable. Drafts, condensation between glass panes, or windows that stick or won’t close properly are clear replacement signals.
Physical damage like cracked frames, rotting wood, or broken hardware obviously needs attention. Less obvious signs include rooms that never feel right, outside noise that seems too loud, or visible daylight around closed windows during the day.
Age matters too. Windows over 15-20 years old, especially single-pane units, can’t match modern efficiency standards. If you’re planning other home improvements or dealing with multiple window problems, whole-house replacement often makes more financial sense than ongoing repairs.
