What red flags should I watch for hiring a window installer in Frederick?

Standard practice is 10-15% deposit, materials-on-delivery payment, and final payment on completion. Watch for window replacement quotes in Frederick that lack line-item detail. A professional estimate breaks out labor, materials, permits, and cleanup separately. Lump-sum bids hide margin and make change orders impossible to evaluate.
