Can you post a photo? I'm a bit unclear on what you're calling an end cap. Is it like a wall that goes up or a wood false tread on the edge of the carpet?

And what do you mean by "replace the entire staircase?" I wouldn't imagine anyone would be proposing to rip out the stringers, just all the treads and risers.

FWIW, we DIY replaced our open-sided carpeted stairs with oak treads, painted risers, and iron balusters, and the materials cost around $1000. It's a fair bit of labor, and tricky to get the handrail angle right, but $8K worth of labor seems a bit rich.

Thanks for the reply!

I don't have a picture of my staircase, but here is an example from houzz.

Basically the drywall does extend up several inches and surrounds the left part of the stairs.

Ellen1234:

Most building codes only allow a 3/8" deviation between stair risers at most. I'm concerned that capping the existing threads will exceed this. It becomes dangerous because it ruins your gait as you move up and down the stairs. You'd be amazed at how much your foot anticipates where the next step will be.

Yes, the entire stair should be rebuilt if the job is going to be done properly. It would be unsafe to do it any other way that changes the height of the rise to be uneven.

I'm still unclear on what anyone means by "Rip out the entire staircase." You do need to replace the treads, but that's a matter of taking off the (likely) pine boards that are underneath the existing carpet and putting down a full tread with a finished edge. Replacing treads is a far cry in my book from rebuilding the stairs. The new wood treads should be about the same thickness as the current tread+carpet, so no re-jiggering of the stringers should be needed.

Thanks for the replies!

Here's another example of the before/after of what I'm trying to do - although my staircase is open on the entire side where the "kneewall" needs to be cut down (like the first link above) versus just 5 stairs.

I did find out that they do plan to just cut down the kneewall and put the new treads over the "newly exposed stringer" (from estimate).

The estimate is just about half of what the full replacement quotes.

One of the other estimates says:

"Remove existing stair & rail systems, stair back. Cut access hole to get under lower section if needed and cut down existing rake wall and install new [list of new stair info, including stringers, treads, risers, etc.].
