If a client inquires for a repair estimate, you may provide precisely that. Changing the sum if more work or components are required than originally estimated is not a problem since it is not a legally enforceable agreement.
But it is best to maintain the pricing as near your predicted price to avoid upsetting the client who has consented to allow you to conduct the task.
Before beginning any work, contact the client and explain why the additional expenditures are necessary and ask for their consent to proceed with the project.
