shueless:I am considering Small Claims Court. The
large retainer fee is a big reason for that.
Also, it seems small claims may give me a
better chance with the warranty issue.
Small claims court is a good idea for your situation. The IL limit is $10,000.
Some points to consider:
1 - You can sue in your local court.
2 - You will have to serve the statutory agent of the manufacturer. You can find out who to serve by calling your secretary of state or checking your corporation commission website.
3 - You will need an estimate for the cost of replacing the vinyl siding on that side of the house.
4 - You will need an expert to come to court to testify that the damage is due to a product defect. That expert should be and engineer who can conduct labratory tests on the siding. That expert should have experience and qualify as an expert witness in court. I don't know where you would find such an expert but you can count on spending $1000 to $2000 for his services and his testimony.
As a claim rep I have hired experts to testify in lawsuits.
If you don't have an expert, you will lose.
If you try to use the contractor as an expert, you will lose. The manufacturer's expert will run rings around him.
Number 4 is the toughest part of preparing your case so I suggest you start googling for your expert before you file your lawsuit because you'll be wasting your time otherwise.
