A threshold strip at the bathroom door is a small job that a family often agrees to quickly and then regrets once the work is done. The paperwork decides what you actually get. Before anyone grinds, replaces, or adds a strip, make the estimate name the finished height, the work area, the warranty, and the cleanup, in writing.

Know what you are holding

An estimate is a rough figure for the work, a quote is a fixed offer, and a contract is what you sign and both sides must keep. Ask which one you have. A phone call or a text message is none of the three, and it will not help you if the strip lifts a month later.

Ask for the finished height

The number that matters is the height of the finished threshold edge at the bathroom door, measured from the floor she walks on. Ask the contractor to write that height, how it is measured, and the material the strip is made of. A written height is a promise you can check. A word such as low or flush is not.

List what the written scope must name

Check that the scope names which door and which floor surfaces meet at the strip, whether the door needs trimming and who pays for that, the adhesive or fastening method, the warranty period and what it covers (the strip, the adhesive, or only the labor), who returns if the strip lifts, and what cleanup is included. If any of these are missing, the job is not finished on paper even when it looks finished on the floor.

Compare two written estimates line by line

If you get two, put them side by side and compare the same lines: finished height, warranty, cleanup, and return visit. Two estimates that name different things cannot be compared, and the cheaper one may have left out the part that protects her. Keep both on file with the signed contract, and keep a copy with her other household records.
