Common Questions
Is this a subscription?
No. You pay once, you get your letter. If you need another letter in the future (for a new transaction or a different reason), you can order one then. There are no recurring charges.
Do I need this if I just had my foundation built?
Probably not. Your original PE-stamped foundation plans typically satisfy lenders and insurers for the first few years. This service is for when someone specifically asks for updated or current documentation.
What if my original foundation was engineered by someone else?
That works. We review the existing plans and current condition regardless of who designed the original foundation. We just need your original plans and current photos.
Does this work for non-Boxabl homes too?
Yes. While this page is focused on Boxabl foundations, we provide certification letters for manufactured homes, modular homes, and traditional construction. Learn about manufactured home certifications.
