Frequently Asked Questions

How do I choose the right NDT inspection company?
Start by identifying your project requirements: Verify ASNT Level II/III personnel certifications are current. Confirm they have experience with your specific NDT method. Check insurance and safety records for field work. Ask about equipment calibration and reporting standards. Our directory lets you compare NDT inspection companies side by side, filter by certifications and location, and request quotes from multiple suppliers at once — all for free.
What certifications should I look for in a NDT inspection company?
The most important certifications depend on your industry. Common ones include ASNT Level III (NDT expert), API 510/570/653 (pressure equipment), ISO 17025 (lab accreditation), Nadcap NDT (aerospace), CWI (welding inspection). Use our certification filter to find suppliers that meet your specific quality requirements.
How much does it cost to work with a NDT inspection company?
Pricing varies based on several factors: NDT method required, number of test locations, accessibility of the inspection area, certification requirements, urgency and scheduling. The best approach is to request quotes from multiple qualified suppliers through our free RFQ system to compare pricing and lead times.
Can I request quotes from multiple NDT inspection companies at once?
Yes. Our multi-supplier RFQ system lets you select up to 10 NDT inspection companies and submit a single quote request. Each selected supplier receives your project details and can respond with a quote. This saves you time and helps you compare offers.
What is the typical lead time for NDT inspection companies?
Most NDT companies can mobilize field technicians within 1–5 business days. Turnaround and shutdown support may require advance scheduling of 2–4 weeks. Lab-based testing typically takes 3–7 business days.
