Fixing handrail on concrete steps-Can’t get bolts out. What now?

honestly, I dont know, but the first thing I would do is look at the underside of the railing to see if that can be disconnected ( if it’s wood). If it is all one piece, I think you need to talk to a pro, because it all depends on how it was installed, and what products were used. And they may just have the right tool or finesse.

This sounds like one for the experts, but if you want to search further, call your local College's Extension Service. You tell them your problem and the same day an expert calls you back with an answer.

How to Fix a Loose Metal Railing Post

One of the most popular and durable types of railings are metal railings. I’m a fan of metal because it’s stronger than wood, requires less upkeep, and doesn’t expand or rot. It also comes in all types of designs and a good quality metal railing will have several durable coatings to make it resistant to corrosion and essentially maintenance-free. I’ve always loved the clean modern look of metal railings, too.

But even durable metal railings can loosen with repeated exposure to rain and wind. Rain, especially, can cause metal to rust at joints where there are bolts and screws, which is why it is important to choose high-quality galvanized hardware. But rust doesn’t mean that the railing has to be completely replaced. If you follow a few simple steps, you can repair your metal railing as good as new.

The steps for how to fix a loose metal railing post are:

1. Remove any rust from the loose railing and bolt holes until only metal is visible.
2. Tighten any loose screws or bolts.
3. Remove old damaged bolts and widen holes if necessary.
4. Replace old bolts with new carriage bolts.

Fill with anchoring cement or metal epoxy.

If the bolts are loose enough at the top, I would use a saw and cut them off. Then I would replace with a larger bolt set in 2-part marine epoxy.

If you can't do that, I would mix 2-part marine epoxy and pour in the concrete holes and hold the railing or support so the railings are straight until it sets up.

You might mix the epoxy and pour into either a big irrigation syringe or like a BBQ ketchup bottle with the narrow pointy top to get it into the old hole. https://www.dollartree.com/Cooking-Concepts-BBQ-Condiment-Bottles-2-ct-Packs/p347516/index.pro
