Stairs and repairs
The stairs are the part of the floor everyone touches.
Treads, risers and nosings that match the floor they land on. Refinished in place when the wood is there, rebuilt when it is not. Plus the repairs that keep an old floor from becoming a new one: water damage, pet stains, gaps, squeaks and board replacement.

Stairs
Three ways a staircase gets done
Which one depends on what is under the carpet, and we do not know until it comes up. We quote a range and confirm on the day.
Repairs
Fix the boards, then make the fix disappear.
Anyone can swap a board. The work is in making the new wood match the old, and that usually means sanding and finishing the area as one floor.
Questions
What people ask about stairs and repairs
What is under my carpeted stairs?
In most Boston-area homes built before 1960, real oak or pine treads, usually with hundreds of staple holes and a paint line at the edges. Those can be sanded and refinished in place. In newer construction, it is often construction-grade pine or plywood meant to be covered, and the treads get replaced with new oak or a retread cap.
Can a damaged board be replaced without redoing the whole floor?
The board can be replaced. Making it invisible is the hard part: a new board finished separately never matches the color and sheen of a floor that has aged. For a true match the repaired area and the surrounding floor are sanded and finished together, usually the whole room. We will tell you which option you are looking at.
Can you fix squeaks?
Usually. Squeaks are movement, either the floor against the subfloor or the subfloor against the joists. From below, if there is a basement ceiling open, we shim and screw. From above, we use trim-head screws driven at an angle through the board into the joist, filled and finished. Not every squeak in a 120-year-old house can be silenced, and we will say so.
