Sometimes you don’t need the whole building gone — just a wing, a wall, or a structural piece to clear the way for a remodel or addition. That’s where partial demolition comes in.

Partial demolition means removing a targeted part of an existing building while leaving the rest structurally safe and ready for renovation.
Typical examples:
Tearing down an old garage attached to the main house
Removing a porch or deck
Cutting back an outdated second story or bump-out
Removing interior load-bearing walls for an open plan
Separating attached units for redevelopment
| Scenario | Why Do It |
|---|---|
| Open floor plan remodel | Knock out a structural wall to open kitchen/dining |
| Garage or porch removal | Clear room for new addition or larger garage |
| Second story removal | Replace aging upstairs with new code-compliant frame |
| Unsafe addition | Old bump-out, porch, or sunroom has failed |
| Lot split | Remove shared garage or carport in duplex split |
Example: Denver, Boulder, Aurora all require full PE oversight if you alter load-bearing parts — Rocky handles it all.

| 4. Precise Tear-Back | Cut structural elements in controlled sequence | Clean removal, no damage |
| 5. Debris Sort & Haul | Separate concrete, wood, metal — recycle what’s clean | Cuts landfill cost |
| 6. Final Edge Prep | Seal or brace exposed edges for framing | Ready for remodel crew |
| 7. Deliver Logs & Close-Out | Provide PE letter if required, final grade if needed | Pass final city inspection |

Same-week site walk. PE plan. Clear, safe tear-back.
Q: Will my house need extra beams after?
Maybe — we’ll design it, file it, and your framer installs permanent supports after our tear-back.
Q: Do I need to move out?
Small interior or wing? Usually no — we contain dust & secure the edge.
Q: What if asbestos is found?
We coordinate licensed removal under Reg 8, then finish the cut-back safely.
