One of the most significant advantages of fiberglass stairs is their low maintenance requirements. Unlike wooden stairs, which require regular treatment to prevent decay and insect infestation, fiberglass stairs are resistant to both. A simple wash with soap and water is often enough to keep them looking pristine. This ease of maintenance not only saves time but also reduces long-term costs associated with repairs and replacements. Furthermore, fiberglass doesn’t absorb moisture, which means that it stands up well to spills and weather-related moisture damage, making it an ideal choice for outdoor and indoor applications alike.
