Need advice on stair handrail
Hey there, so my auntie is turning 80 and currently doesn't have a handrail on the bottom portion of stairs which makes me worry that she'll lose balance and fall some day as she's growing older. I was looking at the existing railing on the upper portion of the stairs and I was trying to figure out if there was a part number, but found none. It looks like it's cast iron and the angle is perfectly designed to fit the stairs, so I doubt I'll find something similar (unless there's a standard angle?) but I don't think I've ever seen this type of railing before - I can't even tell how they mounted that railing.
I guess my question is this: Does anyone have any suggestions on what you think my options might be here? Any links to solutions that might work would be appreciated. I'm starting to research to see how I can help her (even if it means just becoming educated on what price I should expect if I were to hire someone to do this if I find I can't tackle it myself; I am an electrical engineer, but I don't really have access to tools or much experience with home ownership as I've rented my whole life, but I'm not afraid of learning, though I want the result to ultimately be safe, which is the primary objective, so I'll leave the work to someone else if I figure I'm not the best person for the role). Let me know your thoughts - I'm trying to plan to finish this before 2027 if possible. Thanks everyone!
