Plumber.

Yes. Specify pipe materials (copper, PEX, PVC, cast iron, black iron) and systems (supply, DWV, gas, hydronic) you work with. This detail demonstrates breadth of expertise. Different projects require different material knowledge, and hiring managers match your specific skills to their project requirements when reviewing resumes.

List OSHA 10 or 30, confined space entry, and any trenching and excavation certifications prominently. Include backflow prevention tester certification if applicable. Safety credentials are increasingly required on commercial job sites, and presenting them demonstrates professionalism that distinguishes licensed plumbers from general contractors.

Most Plumber resumes should be one page for candidates with under 10 years of experience and two pages for senior professionals. Prioritize relevance over length. Every line should earn its place by demonstrating value to the target role.

Use professional, readable fonts like Calibri, Arial, or Garamond at 10 to 12 point size for a Plumber resume. Stick to black text, clear section headers, and generous white space. Avoid decorative fonts, bright colors, and complex layouts that can cause ATS parsing errors.

Portfolios are highly valued for Plumber roles in creative, design, or technical fields. If your work is visual or project based, include a link to your portfolio in the resume header. Even if not required, a portfolio demonstrates initiative and gives hiring managers a deeper look at your capabilities.
