Need honest mason/masonry company to assess window lintels

Hi! I am in contract to buy a house in Spring, TX and the window lintels are rusted. I need a true and honest assessment of them. I have someone going out today, but I always worry about whether a professional is being truthful or giving their opinion based on procuring a job. I know they are structural and expensive to fix, so this is the make or break on buying this house. Personal recommendations are often better than a Google search.

Thank you!
