Replacing Drywall vs. Refinishing Drywall

[Matt Vaughn]

Guys, I have removed and replaced drywall for 2 of the 4 walls of a bathroom I'm working on (removed to install the tub) in Maryland.  The other two walls are in fine condition (need a patch or two only.  

If I sand the old walls, when I paint the whole room, will the old walls look different from the new drywall walls?  Would you recommend that I consider replacing drywall to provide a consistent finish?  

Thanks for the feedback.

First of all that's a great question.

Not knowing the finish on the two remaining walls I'll give you my two cents.

• If the walls have some type of Orangepeel texture (As is common in (Southern California) I would leave them in place and just refinish the walls. This will save you labor and money on material.
• if the walls have a smooth finish, then I would probably also just leave the walls. Unless the remaining walls have some type of Mold. 

hope this helps.

Cheers.
