A while ago I had some water damage inside the house and I would really like to fix it

Is this something I can just patch up with drywall putty and paint over it, or do I need to cut out this section and put a patch panel in?

From the looks of it, they used latex paint
Can i cut the piece of paint that had water behind it, sand the edges and repaint it?


And how do recreate the texture on the ceiling?

Thanks guys

I would cut out a larger area than what you think, since mold growing in there could cause health problems.
 
There is no saving wet drywall. Drywall is pretty easy to work with. Agree about Youtube. I did all the electrical in my basement, when I finished it, with a how to book and Youtube. Had a professional come in to check it before final hookup and he was impressed. Amazing the stuff you can find there, after you weed through the BS videos.
 
The other guys are right. Cut out anything which got water logged, and replace. Cut the latex paint,and peel it back as far as you can. Drywall isn't hard, but can be frustrating to learn and takes a lot of effort. The good thing is, it's always easy to sand/remove and redo until it looks better.
This guy has got a great channel:

He's easy to understand, and does good work.

My biggest suggestion would be: don't try to do small patches, surprisingly it's easier to just replace an entire surface/sheet than it is to try and patch anything larger than your hand..
 
If not near to a stud or rafter, you could patch a larger hole (red) by gluing some cardboard (green) behind it to bring the replacement piece (blue) you cut flush for you. Some wire looped through the cardboard can provide a means to hold it in place for you while the glue dries. Cut the wire off and glue in your patch and finish up with the mud and sand ritual.

Ugh. Screw fixing it with a patch. New sheet and sleep easy at night. Or you know you'll fail a mold test when you go to sell it.
 
Cut out bad Sheetrock from stud to stud. Screw new patch in and tape with Sheetrock tape. After 3 skim coats of drywall mud, sand and thin mud till almost runny . Dip a stiff paint brush in mud and flick mud on patch. Lightly brush to achieve texture
 
Used to do these repairs all the time. I will assume that you have already fixed what caused the problem in the first place. In your first photo, water got in behind the paint and softened it up. More water coming in means higher hydraulic pressure and a bulge starts to form, more water and it starts to look like a balloon. If you were lucky it burst out the bottom and self drained. Strip off the the lose paint, it should just peel. Use a sharp knife and score an area about twice the width of the damaged section. Just score thru the paint, not the skin of the board. Because this part is vertical, the water should not have caused much damage, if any. Remove loose edges and scuff with an 80 or 100 grit sanding block. Apply a thin coat of all purpose drywall mud (this has a glue in it and is why it is used for taping) as a base. You don't have to be perfect as a thin coat of drywall Topping is going over this. That coat will be the one you sand to perfection with 220 grit or higher. Prime the repair the next day and paint the day after that. Couple of coats and you won't even notice it. Feather it out to get the best result, or paint until you get to a corner. Quick answer to the texture is a Crows foot brush. That area is a little more complicated to fix. PM me if you want mt .02 on that.
 
Try not to bend up your edges when demo-ing.. They should be metal or plastic.
 
Areas where insulation (or not) spray with chlorox or similar before new drywall
