FAQs
Retaining Walls questions.
Do all retaining walls need permits?
Permit and engineering requirements vary by height, load, site conditions, and local jurisdiction. THC screens wall projects before accepting work.
Does THC build large retaining walls?
THC focuses on residential hardscape work and uses stop-work/escalation rules for walls that require engineering, permitting, or specialty construction.
Is drainage included?
Drainage is addressed based on site conditions and wall requirements. It is not treated as a cosmetic add-on when it is structurally needed.
How much does a retaining wall cost in the Triangle area?
Cost varies with wall height, length, material, and drainage requirements. THC provides a clear written proposal after reviewing your site.
Do retaining walls require permits in Raleigh, Apex, or Cary?
Walls over a certain height may require permits in Wake County municipalities. THC advises on permit requirements before work begins.
