SPEC Home Services maintains every credential and license required to inspect Minnesota homes — and several that go above the licensing minimum.
Minnesota Department of Labor & Industry — Licensed Home Inspector. Minnesota requires home inspectors to be licensed under MN Stat. 326B. Derek Vandenberg holds an active Minnesota DOLI home inspector license, current for the present licensing year. The license is verifiable through the Minnesota DOLI license lookup at dli.mn.gov.
InterNACHI Master Inspector (CPI). The International Association of Certified Home Inspectors is the largest professional inspection organization in the world, with the most rigorous education and continuing-education requirements. Derek's CPI ID is NACHI24091107 — verifiable on the InterNACHI website at nachi.org.
FLIR Level 1 Certified Thermographer. Thermal imaging without proper training is just colorful pictures. Derek holds the FLIR Level 1 Certified Thermographer credential, the recognized industry standard for residential and light-commercial thermography.
InterNACHI Master Inspector Mold Inspector. Mold inspection requires specific training in moisture mapping, sample collection, lab coordination, and report interpretation.
InterNACHI Master Inspector Radon Tester. Radon testing has specific protocol requirements (test duration, environmental conditions, chain-of-custody) that affect whether results are court-defensible.
General Liability Insurance. SPEC Home Services carries $1,000,000 per occurrence / $2,000,000 aggregate general liability coverage. Certificates of insurance are available upon request for transactions requiring lender or institutional documentation.
Errors & Omissions (E&O) Insurance. Professional E&O coverage at $1,000,000 limits, specific to home inspection professional services. This is the coverage that protects you if an inspector misses something he should have caught.
InterNACHI requires 24 hours of continuing education annually. Derek maintains substantially more than the minimum, with focused continuing education in commercial inspection, advanced thermal imaging applications, and Minnesota-specific defect identification (ice damming, attic mold patterns, frost-heave foundation issues).
Every SPEC Home Services inspection is conducted to the InterNACHI Residential Standards of Practice or, for commercial work, ASTM E2018-15 (Standard Guide for Property Condition Assessments). These are the recognized industry standards — the framework against which inspector performance is evaluated in disputes.
