I hired a company to install laminate flooring on my 14 stairs between the downstairs and upstairs in my home. On the right side looking up the stairs, there are no visible gaps between the wall and the stair treads (what I call the stair step). On the left side, most of the steps have visible gaps between the wall and the treads, and some of the risers show gaps between the wall and the riser. The gaps appear to widen at the furthest point from where the tread and the riser intersect (what I call the edge of the step). The installation company tells me that gaps are normal in stair installations and advised me to fill the gaps in with wood putty. I understand that a gap is required in laminate floor installations because the floor floats, and is not glued down. But, in the case of the stairs, the installer glued down the laminate.
I have two questions:
1. If there are no gaps on the right side of each step, couldn't the installer cut the wood close enough on the left side of each step so there would not be any gaps?
2. Is there a standard in construction that states that the gap should only be an acceptable width (maybe 1/16 of an inch)?
I would like the installation company to reinstall the stairs with no visible gaps on either side of the stair treads or stair risers, but I don't know if my request is justified.
Thank you for any advice and direction you can provide me.
