Drywall

I have a older home, 1920's and little has been done. Until recently, the upstairs was closed off, and realized the old plaster and lathe is crumbling. Can you just drywall over it? I was thinking of getting a contractor, but wondering the cost. Was looking at the cheapest and easiest way. The painting and taping I can do, just concerned with condition of current walls. There are 2 rooms, 10 x 10 and a stair way going up stairs, all done in plaster and lathe with the popcorn paint.

Any help or advise would be greatly appreciated.

Yes you can. Remove any loose plaster and as long as you know where the studs are and if there able to hold up to the drywall.

I agree with Dave, this is the most cost effective method depending on the condition of the wall.

Thanks,

Installing new drywall sheets over top of the plaster is the best solution. I would not recommend coating the old plaster with mud to repair or add on anything. This tends to cause the plaster to let loose with the renewed moisture and fall off in large clumps. It is very difficult to fix old plaster in this manner.

I have worked on alot of older houses similar to yours and people drywall over to basically cut corners or get the job done for cheaper. I recommend against that as your walls are probably insulated with wood chips that settled and fell to the ground many years ago and you have no vapour barrier. Your ceiling and exterior walls should be re insulated a proper vapour barrier should be installed. It may cost a little more and will be more work ( make sure you / whoever you hire hoards off area wears a mould / asbestos rated mask and run a HEPA machine to filter out what's lurking behind those walls. Everything mouldy should then be sprayed with pure bleach several times to wash mould away and let to dry out for a day or 2 before insulating and installing vapour barrier.
