When to Call Us

Most North Carolina engineer-letter requests fall into four categories: permit letters (for renovations or load-bearing wall removal), insurance letters (often after storm or impact damage), HOA or condo letters (deck attachment, balcony, or structural-modification approval), and lender letters (for refinance, manufactured-home permanent foundation, or transaction-closing structural questions). Each carries a different scope, which is why pricing varies. A small single-issue letter is materially cheaper than a full pre-purchase inspection with a stamped report.

Common signs and scenarios

  • A permit office, HOA, lender, or insurer specifically asked for a PE-stamped letter
  • Your home inspector recommended 'further evaluation by a structural engineer'
  • You are refinancing and the lender flagged a structural item
  • You filed an insurance claim and the adjuster requires engineering documentation
  • Your HOA requires a stamped letter before approving a deck, balcony, or addition
  • You bought a manufactured home and need a permanent-foundation letter

Frequently Asked
