Deducting for Damages to Hardwood Floors in California

At the pre-move out inspection, I noted large gouges and scratches all over the hardwood floors. At the final inspection 2 weeks later there were dents all over the hardwood floors. Tenant did not fix any of scratches, gouges or dents. The floors had no marks at the start of the tenancy. According to two floor servicers, because the wood is engineered, all of the floors would have to be refinished to repair the scratches/gouges which would be very costly.

Can I deduct for such damage to the floors? If so, how do I calculate the damages? Must I get the work done if I deduct for damages?

Thanks in advance.
