What does your contract say? Usually they list a timeline for "punch-list items", which is what you're describing.

You lost most of your leverage when you closed, so at this point it's continue to ask for the contract to be fulfilled. If you continue to have issues you can get a lawyer to write a letter to that effect. Beyond that, it's live with it or sue your builder.

The construction contract should stipulate a timeline for you as the owner to inspect the premises and generate a punchlist. The countdown should begin from the time you received the certificate of occupancy from the city or certificate of completion from the builder if the build is rural. The standard under NAHB is 3 days to inspect, generate, and deliver a punchlist to the builder, however this timeline is adjustable during contract negotiations prior to contract execution. If the punchlist timeline has expired you might look into a warranty claim depending on the issue, this is typically one year from completion, but can also be adjusted per contractual agreement.

I would also add that a builder with integrity would fix the issues if they are notified within a reasonable amount of time, regardless of contract lingo, and in my mind nine days is well within reason. We have stipulations in our contracts for protection, but I personally would much rather keep my clients happy than be a hard a** over a couple days.
