replacing rusted joist hangers

Mr Chips · 06-27-2010, 07:23 PM

We have a vacation home that sits right on the water at the bay. Their is a small deck that was built using those metal USP joist hangers. the have been there for 20+ years and are rusting pretty bad from years of salt air.

I'm thinking i should replace them. My plan was use a prybar and claw hammer, take one out, put a new one on, move to the next one. I'm thinking that doing one at a time, should be no risk of collapsing, so shouldn't need to brace anything. Sound right or am I missing something?

need to replace some badly rusted joist hangers holding up a deck at the shore. Is it as straightforward as it looks, just pry and pull nails, take old one off , nail new one on, move to next one?

Good plan, if you’re in a salt environment and don’t want your grandkids to go through the same thing use stainless steel hangers.

Just be sure you use the right kind of nails (those designed specifically for use with hangers).

Since you are retrofitting these, and you might be putting fasteners back into the same holes, here is a suggestion: Dip the nails into an expanding polyurethane glue (Gorilla Glue or similar from Elmers) before you put them back in again. If the wood is bone dry, put a drop of water in there with a syringe first to activate the glue. The glue will foam up and fill in the voids of the grain where the old fastener was, and it will tremendously improve the pullout strength.
