What red flags should I watch for hiring a window installer in Marlborough?
Be cautious of window replacement contractors in Marlborough who pressure you to sign same-day. Legitimate contractors expect you to get competing bids and will hold their price for 30 days. High-pressure sales tactics correlate with inflated pricing. Any Marlborough 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. In Marlborough, window replacement on homes over 42 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.
