Fiberglass Window Installation: A Comprehensive Guide
Fiberglass windows have become increasingly popular in recent years due to their exceptional performance, energy efficiency, and low maintenance. At FiberGlass Singapore, we specialize in professional fiberglass installation for all types of fiberglass products in homes as well as business environments.
Benefits of Fiberglass Windows
- Fiberglass windows and doors are low-maintenance and resist swelling, rotting, warping, and corrosion.
- They do not require repainting like wood, but the material is paintable if you prefer to change colors down the road.
- Fiberglass windows are energy-efficient, durable, and possess a classic appeal that complements any home's architectural style.
Cost of Fiberglass Window Installation

The average cost to install new fiberglass windows is $400 to $1,000 per window, as of 2026. This includes the cost of the fiberglass window itself, plus the cost of labor and installation by a professional window contractor, which should cost between $70 and $150 per window installed.
However, the overall installation cost can vary based on factors such as the number of windows, frame material, glass type, hardware, and labor. Factors such as the type of window (casement, double-hung, or slider), frame material, and energy efficiency features can all affect the final installation cost.
