I am a General Residential Contractor in Rockport Texas who had sucessfully completed a large 2 story remodel and large room addition and was not paid. Nearly $40,000.00 Then a 2nd homeowner refused to give me my 2nd of 3 Checks that the Morgage company had mailed them for me, $18,600.00 already earned. It cost me my buisness and I lost everything due to non payment
You should consider writing a letter by certified mail, return receipt requested, to your customers to set out the fact and to demand payment. Attach your unpaid invoices and photographs of your completed work. Make sure that your letter is business like and professional as it may be evidence later.
If need be, consider filing suit using your letter as evidence.
Good luck.
