First thing to do is to read the contract.
There should be a section about drainage performance and remedies.
One way builders save money is not to consolidate excavations when they're backfilling. That means after a hole's been dug it should be filled in by layers with each layer compacted. This keeps the land from sinking.
Don't know if it was incompetence or negligence or oversight that's causing the ponding.
The fix is fairly simple.
Depending on the depth of the pond it could be filled with top soil then new grass planted.
The key is to look at the ENTIRE property and its relationship to the surroundings.
Your property can't drain on to a neighbors.
The discharge from the gutters should be at least five feet from the home.
There could be soil with A LOT of clay. This makes it hard for the rain to drain.
The clay can be dug up and replaced with river rock -- about 1 to 1 1/2" in diameter. Then covered with soil then seeded.
The rain will be held in the space between the stones and slowly released into the grown.
A landscaping contractor would be the person to call.
An approximate price to fill with top soil and seed is 1700$. Would be less if your daughter's in the country.
To excavate, add rock, add soil + seed price would be around 3500$
If the builder won't budge you might contact your local Habitat for Humanity or Rebuilding Together. They help people with disabilities. . .
