I worked as a sub sub contractor for company that works directly with Home Depot - we did tile for homeowners that contracted Home Depot and this company subcontracted my company and with held approx 5-10% each job - we stopped working for them over 12 months ago and retainage as per our agreement would be released as per the month of April its May and no Ck but there now saying because of Covid there not working I’m waiting for retainage for 13 months now. Anything we can leaf ally do or any definite law that backs me up with an email I can send in a professional manner that would move this process along. Thanks
