FAQs

1. What is the advantage of a fiberglass door?

One of the most significant advantages of fiberglass is their durability. Unlike wood, they don’t warp, rot, or corrode, which makes them a long-lasting option. This durability ensures that they can withstand various weather conditions without requiring frequent repairs or replacements.

2. What are the issues with doors?

Common problems include doors not fitting in non-square openings and potential cracking of the fiberglass skin. If your door doesn’t fit, check if trimming is possible according to the door’s specifications. In the case of cracks, use fillers like Bondo for repair.
