How long till our House Wrens fledge?

Question

What is the interval between broods for House wrens?
I have wrens nesting in an A/C duct. I want to add a grid to keep them out but only after this brood leaves.

Naturalist's Response

After hatching, House Wrens will take about 14 to 16 days to fledge (leave the nest).

I would check after that many days just to be sure they are gone before installing the grid to prevent them from returning.

Thanks for asking!
