Choosing a Contractor

Selecting the right contractor, consultant, or service provider is critical to the success of your preservation project. To ensure that your project is completed to the highest standards and in compliance with preservation guidelines, here are some essential steps to consider when making your choice:

  • Request multiple current references from the contractor that are relevant to the type of work you’re undertaking.
  • Ask the contractor for a cost-estimate in writing for proposed work to be performed that is connected to a clear scope of work.
  • Make sure they are a licensed and insured contractor.
  • Check if the contractor will certify that their work conforms to federal, state and local regulations and requirements, particularly to the Standards for Rehabilitation if historic tax credits or grants are being utilized.
  • Verify that the contractor carries workers’ compensation insurance.
  • Make sure the contractor or consultant has experience with similar preservation projects, as work on historic buildings often requires specialized knowledge, skills, and sensitivity to historic materials and structures.
