According to Remodeling Magazine’s 2025 report:
- Fiber cement siding ROI: 69.4%
- Window replacement ROI (vinyl): 61.2%
- Window replacement ROI (wood): 56.3%
Compare Value Additions

Next, let’s break down what actually affects window costs across Long Island.
What Affects Window Installation Costs on Long Island?
Material choice, frame style, and labor availability are the three largest cost drivers.
Primary Factors That Affect Window Installation Cost:
- Frame Material: Vinyl is the most affordable; wood and fiberglass cost more.
- Style: Bay windows, custom arches, or triple-pane increase labor and material pricing.
- Permits & Local Codes: Town-specific zoning laws and replacement permits add to the overall budget.
- Labor Market: In 2025, Long Island’s contractor rates range from $100 to $180/hour, depending on location and certification.
- Energy Ratings: Windows with Energy Star labels, low-E coatings, and insulated spacers carry a higher upfront cost but deliver better thermal performance.
What Is Fiber Cement Siding and Why Pair It with New Windows?
Fiber cement siding is a durable blend of cement, sand, and cellulose that resists rot, fire, and pests.
Brands like James Hardie dominate the Long Island market due to their weather resilience and warranty coverage.
Why Homeowners Combine Siding and Window Projects:
- Moisture Barriers: Both require house wrap and flashing systems for water control.
- Trim and Joint Integration: Coordinating trim boards, caulking, and siding joints reduces air leaks.
- Labor Efficiency: Contractors often offer bundle discounts when installing both.
Key Fiber Cement Components:
- Lap Siding: Most common look, overlaps for weather protection.
- Soffits & Trim: Finishing elements enhance design and seal gaps.
- Moisture Barrier: Required layer beneath siding for proper drainage.

When Should You Replace Windows vs Fiber Cement Siding?
Best practice: Replace both windows and siding together—or windows first.
Seasonal Timing Recommendations:
- Spring (April–June): Ideal weather, lower labor demand.
- Fall (September–November): Contractors finish backlog; good availability.
- Avoid mid-winter unless an emergency.
If a budget limits you to one upgrade:
- Choose windows first if the glass is cracked or fogged, or frames leak.
- Choose siding first if there’s visible rot, warping, or paint failure.
Allow 3–6 weeks lead time for materials and 7–14 days for project duration depending on size.
