I work like subcontractor in this project, supply windows and doors. In the terms and the payment I should receive final. 25% after delivery. The GC asked me can I start installation because he got some issue with owner, so it’s really help him to collect the payments. Fortunately, it’s not happen. He pay me from the window door portion only 10,000. From 39,000. I just try to show him good faith, and almost finalize installation, that not include our original contract for windows doors. Date of the delivery for windows doors. 2/15 /2023. Last day for installation. 03/26/2023. Please let me know.
