ceiling sagging

Unfortunately, the ceiling sagged as a result of the cleaning I made in a hurry and friends. It was about 6 7 months ago
It was light, but recently it almost touches the back of the sitter. Can I fix this good or bad
Or should I go to the master and get it done from scratch
And how much is average. I am waiting for your help and information.

Thanks

My brother is 500 TL, is being eaten in Konya or the same problem is in my car. You can try it yourself, but if you damage the material under the fabric and sag again, you need to change that material as well then it will be more expensive.

I had the same problem. I went to a few upholsterers, they gave about 200 TL. I found one Syrian, he made 150 TL, thanks to him, he was the number ten, he took it from his original fabric, and he made it clean in 3 hours. You can even do it if you can.
