Before hiring a contractor, ensure they are properly licensed, insured, and bonded, as this protects you in case of accidents or substandard work. Review their portfolio of previous projects, especially those similar to your needs, to assess the quality of their work. Check online reviews and ask for references to gauge their reliability and professionalism. Make sure the contractor provides a detailed written estimate outlining the scope of work, costs, and timelines. Clear communication, a fair payment schedule (e.g., not requiring full payment upfront), and a willingness to answer your questions are also key signs of a trustworthy contractor
