Stair trim and skirt boards
A stair is the hardest trim in the house because nothing on it is square and everything on it is seen from below.

Quick answer
How much does stair trim cost in Maryland?
A scribed skirt board runs $450 to $1,100 per flight, tread and riser trim $55 to $160 per tread, and balusters $30 to $85 each fitted. Refixing a loose newel post back to the framing is $180 to $550 and handrail is $35 to $90 per linear foot supplied and fitted. Skirts are priced per flight because the scribing work does not scale neatly by the foot.
The work
What stair trim actually involves.
Stair trim is finish carpentry at its least forgiving. The treads are not level, the risers are not equal, the wall is not plumb and the whole assembly is viewed from underneath where every gap is backlit. A stairwell is also the one place in a house where people are standing still, holding the rail, looking at the work from eighteen inches away.
The skirt board is the piece that makes or breaks it. It is the board running up the wall alongside the treads, and it has to be cut to follow the stair exactly — scribed to each tread and riser so the joint is tight all the way up. The shortcut is a straight board with the gaps filled, and it shows as a wavering caulk line for as long as the stair exists. Cut properly, the skirt is a single clean diagonal and the stair reads as one piece of joinery.
The other half is the balustrade, and here there is a rule rather than a preference. A sphere of four inches must not pass between balusters, and the spacing has to be set out so that it does not — which usually means calculating the baluster count per tread rather than eyeballing an even look. We also deal with newel fixing, which is the commonest thing we find wrong on an existing stair: a newel post that moves when you lean on it is doing none of its job, and it is nearly always fixed to the trim rather than to the framing.

Stair trim and skirt boards
What’s included
Everything the stair trim scope actually covers.
Written into the estimate, not assumed. If something on your job is not on this list, it gets priced and named before anyone starts.
Skirt boards scribed to the stair
01The skirt cut to follow every tread and riser so the joint closes along its whole length. This is slow work with a template and it is the single thing that distinguishes a stair that looks built from one that looks trimmed.
Treads, risers and nosings
02Treads and risers fitted and nosings returned at the open side with a mitred return rather than a square cut end, which is the detail the eye reads from the hall below. Squeaks dealt with from above where we can get at them.
Baluster spacing set out to the rule
03Spacing calculated so a four-inch sphere cannot pass between balusters, which is the code requirement rather than a matter of taste, and set out so the result looks regular rather than merely compliant. Usually that means two balusters per tread.
Newel posts fixed to structure
04Newels anchored back to the framing rather than to the trim, so the post does not move when the rail is leaned on. A loose newel is the most common defect we find on existing stairs and it is a safety item, not a cosmetic one.
Handrail height and continuity
05Rail set at a consistent height above the nosing line with the returns at the top and bottom resolved, so there is something to hold onto for the full run. The CDC material below is a plain reminder of why that matters in a house with older occupants.
Filled, caulked and ready for finish
06Nail holes filled, joints dressed, the skirt caulked to the wall and the stairwell left clean. Painted or stained by us in the same visit where you want it, which on a stair saves a second round of masking.

Stair trim questions

Close enough that a four-inch sphere cannot pass between them, which is the code requirement and the reason most stairs end up with two balusters per tread. It is worth setting out properly rather than spacing by eye, because an even-looking stair that fails the four-inch test has to be redone and a compliant one set out badly looks irregular.
Almost always because it is fixed to the trim or the skirt rather than back to the framing underneath. It is the commonest defect we find on existing stairs and it is a safety issue rather than a cosmetic one, because the newel is what anchors the whole balustrade. It is usually fixable without rebuilding the stair, and we will tell you after we have looked underneath.
Often, and the honest answer depends on access. Where we can reach the treads from above during trim work, shimming and refixing the tread to the stringer solves most squeaks. Where the fix needs access from underneath and the stair is closed in, it becomes a bigger job. What we will not do is call a structural problem a squeak — if a stringer has moved, that is a different conversation.
