What signs of a bad solar installer should Trenton homeowners watch for?
Any Trenton contractor who asks for more than 30% upfront before materials are ordered is a red flag. Standard practice is 10-15% deposit, materials-on-delivery payment, and final payment on completion. Watch for solar installation quotes in Trenton 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. In Trenton, solar installation on homes over 46 years old should include a contingency line item (10-15% of total). Contractors who guarantee fixed pricing on old-home work either haven't looked closely enough or plan to cut corners when surprises appear.
