Finding a Lead-Safe Certified Window Contractor

For pre-1978 homes, window contractors must be EPA-certified to perform renovation work. According to the EPA, verifying this certification protects your family and ensures legal compliance.

What Certification Means

According to EPA requirements:

Firm certification: The company must be registered with EPA (or state agency) as a certified renovation firm

Individual training: At least one person on each job must be a Certified Renovator who has completed EPA-accredited training

Ongoing requirements: Certification requires renewal every 5 years with refresher training

How to Verify Certification

According to EPA guidance:

Check the EPA Database

1. Visit epa.gov/lead
2. Use "Find a Certified Renovation Firm" search
3. Enter contractor name or location
4. Verify active certification status

In Idaho

According to the Idaho Division of Building Safety, Idaho implements its own authorized program. Verify through both:

  • EPA federal database
  • Idaho contractor licensing

Request Documentation

Ask contractors to provide:

  • Copy of firm certification
  • Certified Renovator credentials for assigned workers
  • Proof of training completion

Questions to Ask

According to EPA recommendations, ask prospective contractors:

1. "Are you EPA Lead-Safe Certified?"
2. "Can you show me your firm certification number?"
3. "Who will be the Certified Renovator on my job?"
4. "What lead-safe work practices do you use?"
5. "How do you handle cleanup and disposal?"

Red Flags

According to EPA, be cautious if contractors:

  • Claim certification isn't needed for window replacement
  • Cannot produce certification documentation
  • Plan to skip containment "because it's just windows"
  • Offer significantly lower prices than certified competitors
  • Seem unfamiliar with RRP requirements

Why It Matters

According to EPA, hiring uncertified contractors for pre-1978 home renovation:

  • Creates lead dust exposure risk for your family
  • May expose you to liability if someone is harmed
  • Potentially violates federal law (the contractor, not you, faces fines)
  • Can create problems when selling your home

The Bottom Line

Certification verification takes minutes but provides important protection. According to EPA, never assume a contractor is certified—always verify through official channels before signing contracts.
