Uneven and spongy Floor

I live in a 3 story house, the mid level floor is uneven and spongy. The floor slants from the centre of the property towards each end. When walking you can hear furniture move. Does this point to an issue with the floor Joists?

"Hi, my advice for this problem is to take out the carpet and parts of the floor reinforced some of the joists checked plumbing pipes and electrical cables travel areas because it can be more damages if someone's screwed or nailed that floor before removing parts of the floor and if you don't have money to replace with chipboard floor which one it's best can be fixed back old one with screws and on top of this fixed big sheet of plywood 9mm thickness with some of glue and screws and after that fixed carpet back and cutting 9mm down level from doors. I have around 35 jobs done with the old floor back and the first one it's from 2015 done and the costumer is very happy with it."

"It sure does, you might want to have someone looking at it sooner rather than later"

"Hire a carpenter. Place some requests to determine the issues, the cure and fix. Decide on a budget for labour, techniques to be used and materials and manage your expectations very well. Go through the process of hiring and you'll be learning a lot about what you don't know yet. Don't assume it's easy but just do it as if there's no way around it. Does that work for you? Don't just take information without practice. Fixing up flooring may uncover other problems that you should expect to manage. Maybe you want to also take estimates for radiators, new sockets or wiring work or other plumbing or underfloor heating. Put aside a full week to take appointments and you'll know your situation better than now. Don't expect someone to provide you with the price. It defeats the purpose of the whole hiring process. You don't want someone to learn on your floors or gain experience on your back. You need well-experienced professionals who will transform and increase your house value and atmosphere.

Other things you should consider doing are plumbing, wiring, radiators plastering, fixing up ceilings or insulation. Do all in one go or room by room . Try and play around with the home layouts and transform it for 2021. You'll love it for years to come. Try and take an estimate of how much your home is worth now and improvements that increase it's value. Basic improvements and extreme improvements. Think as if you are a business that try to turn around a profit. Think differently from now. You can be in business with the rest of us. Let us know how it all went. We'll love to have updates from you. Good bye for now and good work!"

"This seems to be an issue with either swollen joists or floorboards at the ends.
Somewhere all the tight boards probably need releasing or joist shaven down.

Sounds like the centre of the floor is bowed in some way"
