Hiring someone solely based on price is not a great idea for a few reasons. The most significant reasons are due to the fact that low bids are usually missing some significant parts of the project. Often the cheapest contractors cut corners in ways that could be dangerous to you or your family. They may use inferior materials or unlicensed subcontractors. Unfortunately, we have seen cases where people have chosen the contractor with the least expensive proposal, only to end up paying significantly more once the contractor added in the missing pieces.
