Installing Door Knocker in Fiberglass Door: Bad Idea?

Posted by leafy02 (My Page) on

I'd like to add a door knocker to my new front door, but it's a fiberglass door and the guy who installed it cautioned me about drilling into it and said I should have ordered it pre-drilled.

Looking around online, it seems like it can be done, but extra caution is needed to make sure the holes on the interior and exterior surfaces are level and that the surface doesn't shatter?

I definitely don't want to ruin my new door--how tricky is it to do a good job, or how likely is it that I'll ruin my door?

RE: Installing Door Knocker in Fiberglass Door: Bad Idea?

pre-drilled would have been the way to go, but it's not an impossible thing to do. The key is to not try to just drill into it. You need a pilot hole to break through the surface and then carefully enlarge the hole to the size you need. The biggest concern is chipping the finish next to the hole. Depending on the style of knocker used, the knocker itself may provide some cover outboard of the attachment holes, and allow for some slop but still have a nice finished product at the end.

a quick google search for "driling a fiberglass door" led to the attached link which seems to provide a reasonable approach on how to do it.

Good luck.
