Ask both contractors the same six questions
Send an identical list rather than reading two differently structured proposals. Ask for the insurance certificate, the screening arrangement with the type of check named, the safety approach for the actual tasks at your premises, the quality method including who inspects and how often, whether any part of the work is subcontracted, and what happens when something falls short. Six questions, answered in writing.
The value is in comparability. Two proposals written to each contractor's own template are almost impossible to compare, because each emphasises its strengths and omits the rest. Identical questions remove that advantage and reveal the gaps, which is the entire point. It also takes very little time, since the questions are the same ones you would ask during the contract anyway.
