Contractor has made a complete mess of work performed. Windows were installed. Windows ordered were not received and company is only willing to reduce the final bill for window only. The crew left quite a mess of metal around the yard and driveway causing a tire to impacted and unrepairable. customer spent hours cleaning up the mess of metal, screws, nails, caulking wold like a reduction of 700 dollars total not just the difference in window price. Contract said after ten days of non payment they will file a lien on the house. $500 difference and a lien not great customer service. How long would this lien be in effect????
