Judging by the photos and not having seen the damage properly, I'd suggest you do it yourself and not go through the insurance company. They seem to be fairly easy fixes. If you claim through your insurance you will find that inevitably your premiums will rise more than normal and some insurance companies might not want to insure you when the insurance is due.
More importantly, it will be classed as an insurance job and you might have trouble selling it.
Just something to think about.
Since you didn't declare them then you will have a tough time getting anything from the insurance people.
