A supplier (also referred to as a vendor) in residential construction refers to a company or individual that provides materials and equipment needed for completing projects. Common materials provided by suppliers can include anything from lumber, paint, and roofing materials, to electrical wiring, plumbing fixtures, and HVAC equipment.

Suppliers provide builders and contractors with access to top-quality building materials and equipment, and often have a detailed understanding of building codes and regulations relating to products they offer. Their expertise is essential for ensuring that the materials being provided meet industry standards, and that all building requirements are met to ensure the safety and structural integrity of completed projects.

Suppliers must be able to deliver materials in a timely and efficient manner. This requires effective communication skills and the ability to manage inventory and logistics effectively. The supplier must also provide exceptional customer service, supporting builders and contractors with any queries or issues that arise during a project.
