Stair tread and riser assembly


When assembling stair treads and risers, is it better to have the tread tucked under the riser or have the riser tucked in between the tread and the stringer riser backing? I am inclined to think the former because that way the tread gets more framing support but the way my current stairs are assembled is the latter, hence my uncertainty. See picture.

You install the risers first and then the treads.

And you also go behind the risers, and give extra attachment and support to the treads in the form of glue and screws through the risers into the back edge of the tread.

Treads are only providing support of a measly 1-1/2", or so... however thick they are. This is not much.

The risers, on the other hand are installed like floor joists are installed, on edge, giving you about 7" of very solid support all across under the front edges of the treads. It makes equally good sense to support the back edges of these relatively thin treads by fastening them into the bottom of the risers.

I even dado the bottom edge of the risers for this express purpose... as shown in these drawings.

Yeah, maybe. I can't really tell. If so, then he already knew the answer to his question before posting.

Risers first then treads. Dadoed is definitely better but not absolutely necessary. Screws are also best but 2 1/2" ring shank nails work great also and are faster. Just make sure that you apply construction adhesive to all wood to wood surfaces.
1. Back of Tread to Riser (dadoed or not)
2. Top of Riser to bottom of Tread
3. Both tread and riser to the stringers.
This will insure that the treads are secure and that they will not squeak.

T is right. Don't be cheap with the adhesive... load it up.

It is interesting, but only because almost nobody does it this way anymore. Balusters which have been dovetailed add a tremendous amount of strength to the handrail.

I tried one at the gym, and it really was a good machine.
