Stair Trim Molding

By Tim Carter
©1993-2008 Tim Carter
Summary: Stair trim molding confuses some rookie carpenters. They realize that stair trim design is perfected when you take the stair trim piece and run it up the stair stringers, but cutting the required angles causes confusion. If you want to learn how to do stair trim and stair risers trim, then this column might be a great place to start.

We are putting a wooden floor in the upstairs of our house. The existing wooden staircase will not meet the new floor along a flat surface. the top of the stairs are even with the unfinished subflooring. How do we join the new floor to the stairs without creating a tripping hazard.

Aimee,
I suggest you hire a seasoned finish carpenter to get you out of this mess.

Dear Brain, I am not the best finish carpenter, YET!! I have started my own handyman business and take jobs as i learn them so to speak. Currently i just want chair rail going up the stairs of a hallway and up at the top all down the hallway and into all the rooms. That part is complete and no problem. Next, I created picture frames basically out of molding and they are inbetween the floor baseboard and chairrail to creat a design. Those were simple in the actual hallway, but going down the stairs in order to make it look good i need to not creat squares or rectangles, but actually parralelograms i believe and i am having a hard time finding the angle, once i want the top of the box to run parrallel with the chair rail, and the other side of the box to run perpendicular with the stair treads if that makes sense

Jared,
Simple. I give some strong clues in this column. Take some straight pieces of thin trim and make a rectangle but use small wing nuts and bolts at the corners. Set the bottom on the stringer and make the sides plumb. Tighten the nuts. This is your pattern. Extrapolate the angles.

I am triming out some stairs in my house with hardwood, and I am wondering what the standard overhang is for the rounded over stairnose. Is 1/2 inch appropriate or considered a tripping hazard?

Dear Tim, I have a closed stair case and would like to know how to make the baseboard that runs along the wall next to the treads meet the height of the base board at the top and bottom of the stairs and the landing.

hello.
sved, in canada the national building code states maximum 25mm (1") nosing. your minimum run should be 210 plus an additional 25mm nosing (from face of the stair riser material to face of nosing material.) however your run is probably higher than that.

according to recent building code, 25mm nosing is considered good practice. this is the maximum size. however it should not be rounded over or bevelled 25mm from the face of the nosing.

Our lower level has stained trim, our upper level has painted trim. The stair joining the levels is stained so the stained trim will meet the painted trim at the top of the stair. More precisely, the trim(stained) on the stair stringer(stained) angles up the stair, then becomes horizontal for a couple of inches at the same level as the painted upper baseboard trim(4" wide). How do I join the two? Just butt join? Should I use a narrow block that stands slightly proud? The trim is an ogee shape.

Paneling was removed from staircase.Drywall cut around the steps as flush as possible. Still does not look neat. Is their a special trim or technique to straighten this out? Thanks
