Where should I put the schema org structured text

Site URL: https://www.bouwen4jou.nl/

Hi

I have used the Schema Markup Generator of https://technicalseo.com/tools/schema-markup-generator/ and tested it on https://search.google.com/test/rich-results to check if it is valid. The markup I created is focussed on local business and type 'homeandconstructionbusiness'. Only where should I put the markup? Should I put in in de code injection for each single page or should I put in the advanced code injection of the footer or header? 

Thank you in advance for helping!

Kind regards,

Niels
