Post-Construction Final Clean for General Contractors

The final clean is the last task before your owner walkthrough. If it slips, your punch list grows and your certificate of occupancy delays. Strong Tower schedules to your walkthrough date, delivers the full closeout scope, and hands you a clean building ready for FF&E installation.

Common challenges

• Final clean scope unclear in the bid package — GC absorbs cost overruns
• Wrong sequencing: cleaning before paint cures creates re-work and callbacks
• Sub-vendor no-shows on short-notice closeout schedules
• Missing COI or DMWESB certification documentation delays bid acceptance
• Construction dust left in HVAC, fixtures, or glass triggers owner rejection

What we deliver

• Full dust-out after rough trades complete — before detail clean starts
• Detail clean of all interior surfaces to closeout spec
• Glass and mirror restoration to original condition
• Punch-list touch-up before your walkthrough date
• COI available for bid packages ($1M CGL)
• COBID 8404 MBE/WBE documentation for DMWESB participation requirements

Questions

When in the construction sequence should the final clean happen?

After paint cures and before FF&E installation. This is the standard closeout sequence on Portland commercial builds. We coordinate with your schedule so the clean happens in the correct window — not before paint, not after furniture.

What is the difference between a rough clean and a final clean?

Rough clean is debris removal and sweep-out during construction, typically between trade phases. Final clean is the closeout clean: dust-out of every surface after all trades finish, detail clean, glass restoration, and touch-up. The final clean is what the owner inspects.

Can you provide a COI for our bid package or subcontract?

Yes. We carry $1M in general liability insurance and can provide a certificate of insurance naming your project and GC as additional insured. We also hold COBID 8404 MBE/WBE certification.

Do you meet DMWESB participation requirements on publicly funded projects?

Yes. Strong Tower is a COBID-certified MBE/WBE firm. We can satisfy DMWESB participation goals on publicly funded Portland-area projects, including those with explicit percentage requirements in the bid package.

What happens if the final clean needs to be rescheduled?

We accommodate schedule changes. Call us as soon as you know the new date. We build schedule flexibility into our Portland-area calendar to handle the common reality that closeout timelines shift.
