State Sheetmetal Works
Owner
I found State Sheet Metal on BuildZoom to replace water table ledge flashings at two levels with .26 gauge galvanized sheet metal. We were extremely pleased with the service that State Sheet Metal provided. We chose State Sheet Metal Works for the following reasons:
• Dan arrived promptly to give us an estimate and provided a proposal for a couple of days.
• The proposal was thorough with no surprises.
• Provided necessary documents; Workmen’s comp, Certificate of Liability Insurance, and Mechanics Lien Waiver & Release
• Dan helped us through the entire process and was very patient in answering all our questions.
• They worked along side with our painter and completed the job as promised in 3 days.
• Customer service and workmanship were excellent.
I highly recommend this company and would hire them again in the future.
