Sliding windows have become increasingly popular in modern architecture due to their sleek design and functionality. They are typically used in large openings to let in plenty of natural light, offer unobstructed views, and improve ventilation. If you're planning to install sliding windows in your home, one of the most important factors to consider is the cost.

Sliding windows prices can vary depending on several factors. These include the material used for their construction, size, energy efficiency, glazing, and installation costs. In this article, we'll look at some of the common types of sliding windows and their average prices, to help you make an informed decision.

Vinyl Sliding Windows

Vinyl sliding windows are a popular option for their affordability, durability, and low maintenance costs. They are made from polyvinyl chloride (PVC), a material that resists moisture, rot, and fading. Vinyl sliding windows typically cost between $250 and $600 per window, depending on the size and design. Larger windows, custom colors, and special features like triple-pane glass can cost more.

Aluminum Sliding Windows

Aluminum sliding windows are another popular option, especially for commercial buildings. They are strong, lightweight, and resistant to corrosion, making them ideal for humid environments. Aluminum sliding windows typically cost between $350 and $800 per window, depending on the size and design. They can cost more than vinyl windows, but they offer better strength and durability.

Wood Sliding Windows

Wood sliding windows are a traditional option that offers a classic look and natural insulation. They are usually made from high-quality wood like mahogany, cedar, or maple, which can be stained or painted to match your home's interior or exterior. Wood sliding windows cost between $500 and $1,000 per window, depending on the type of wood used and the design. However, they require regular maintenance to protect them from rot, insects, and weather damage.

Fiberglass Sliding Windows

Fiberglass sliding windows are a newer option that combines the strength of fiberglass and the beauty of wood. They are highly energy-efficient, durable, and low-maintenance, making them ideal for modern homes. Fiberglass sliding windows typically cost between $600 and $1,200 per window, depending on the size and design. They can be more expensive than other materials, but they offer long-lasting performance and unique colors and finishes.

Installation Costs

In addition to the cost of the windows, you will need to consider installation costs. The installation cost for sliding windows can vary depending on the size of the window and the complexity of the installation. However, you can expect to pay between $75 and $150 per hour for labor, with the entire job taking between 3 to 4 hours. You should also factor in the cost of removing your old windows and any necessary repairs to your window frames or walls.


In conclusion, sliding windows offer a variety of benefits, including natural light, ventilation, and unobstructed views. The cost of sliding windows can vary depending on the material, size, and design you choose, as well as the cost of installation. Vinyl sliding windows are the most affordable option, while wood and fiberglass windows can be more expensive but offer unique features. Be sure to choose the right windows for your home and budget, and work with a reputable contractor to ensure proper installation.
