Post-Construction Cleaning Procedure HowTo
Why this matters
Post-construction cleaning is the highest-margin single-job category in cleaning. New construction or major remodel customers need 4-8 hours of deep cleaning before move-in. Pricing ft + a typical 2,500 sq ft home = ticket. Repeat business from builders + general contractors. This is the working procedure.
When this comes up
- New construction final clean (before sale or move-in)
- Major remodel completion (kitchen, bath, addition)
- Real estate "make ready" between tenants
- Pre-listing prep (home sale)
Different from "deep clean" (recurring residential): post-construction is single-visit, extensive, dust + debris focused.
Tools + supplies
- HEPA vacuum with attachments (NOT regular shop vac)
- Microfiber cloths (multiple colors, color-coded by area)
- Bucket + caddy
- Step ladder (8 ft + 10 ft)
- Squeegees + sponges for windows
- Razor scrapers (for paint + drywall mud + adhesive)
- Putty knife + plastic scrapers
- Detail brushes (toothbrush size + larger)
- Vinegar + ammonia + standard cleaners
- Glass cleaner
- Degreaser
- Tile + grout cleaner
- Wood floor cleaner (Bona, similar)
- Stainless steel polish
- Drop cloths + plastic
- Booties + gloves
- Trash bags (heavy-duty)
Pre-job survey
Before quoting:
- Walk every room with general contractor or homeowner
- Identify: ceiling, walls, windows, floors, fixtures, appliances, cabinets, countertops
- Note construction debris (drywall mud, paint splatters, sticker residue, sawdust)
- Note completed vs incomplete work (incomplete = re-clean needed after final)
- Photograph baseline
- Measure square footage
- Discuss customer's "level of clean" expectation (move-in ready, listing-ready, builder-final)
Quote based on scope + sq ft.
Procedure
Sequence is top-down + dry-to-wet:
Step 1: HEPA dust removal (all surfaces, ceiling to floor)
- Ceilings: HEPA vacuum + soft brush
- Fans + light fixtures: detail dust + bulbs
- Walls: HEPA top-to-bottom OR magic-eraser if marks present
- Window frames + sills: detail
- Door frames + doors: top-to-bottom
- Cabinets: tops + sides
- Baseboards + trim
- Stair handrails + spindles
Dust collected at floor level for final vacuum.
Step 2: Window cleaning
- Razor scrape any paint or adhesive on glass
- Squeegee + wipe sills
- Frames + tracks dry-vacuumed first, then wet-wiped
- Inside + outside if accessible
- Avoid streaks: wipe with microfiber after squeegee
Step 3: Kitchen detail
- Cabinets: top first, then sides, then doors + interior
- Countertops: scrape any residue (caulk, glue, adhesive)
- Appliances: range, oven (interior), microwave, dishwasher, refrigerator
- Fixtures: faucet, handles, soap dispenser
- Backsplash detail (each tile + grout)
- Sink: stainless polish if applicable
Step 4: Bath detail
- Tile + grout: scrub + rinse
- Tub or shower: detail clean
- Fixtures: faucet, handles, shower head
- Mirror + glass
- Toilet: interior + exterior
- Vanity: top, drawers (open + detail), bottom
- Light fixtures
- Floor
Step 5: Hardware + fixtures
- Door knobs + locks
- Closet shelving + rods
- Window locks + cranks
- Switch plates + outlet covers
- Vent covers (HVAC, exhaust fans)
- Drawer handles
Step 6: Floor
- Final vacuum (all surfaces, HEPA)
- Mop hard surfaces (tile, hardwood, vinyl)
- Spot clean carpet if construction debris
- Sweep porch + entry
Step 7: Walk-through + touch-up
- Customer walk-through
- Address any missed spots
- Final photos
Common construction debris
Drywall mud:
- Scrape off with putty knife or plastic scraper
- Vacuum + wipe
- Don't smear with wet cloth (sets like cement)
Paint splatters:
- Razor scrape glass (safe with caution)
- Scrape from tile/grout with putty knife
- Goo-Gone for stubborn
Stickers + adhesive:
- Goo-Gone or rubbing alcohol
- Razor scrape from glass
- Test on subtle area first
Tape residue:
- Goo-Gone + microfiber
- WD-40 for stubborn
Drywall dust (everywhere):
- HEPA vacuum first
- Avoid using regular shop vac (blows fines into the air)
- Damp cloth follow-up
Sawdust (under cabinets, in corners):
- HEPA vacuum + nozzles
- Tackcloth for finish surfaces
Plaster + grout splatters on floors:
- Putty knife + warm water
- Care on wood floors
Specific area protocols
Hardwood floors:
- NO water OR very minimal damp mop
- Use Bona or manufacturer-approved hardwood cleaner
- Spot scrape with plastic; never metal
Tile + grout:
- Sealer applied AFTER final clean (builder responsibility usually)
- Light scrub with grout brush
Stainless steel:
- Polish with grain (lengthwise, not circular)
- WD-40 for fingerprints
- Avoid abrasives
Stone countertops (granite, marble, quartz):
- pH-neutral cleaner only
- No vinegar or acidic cleaners
- Sealer applied separately
Builder relationships
Post-construction cleaning + builders is symbiotic:
- Same crew at multiple new builds
- Builder calls when next house is ready
- Repeat business; minimal CAC after first
Build relationships with:
- General contractors (residential)
- Custom home builders
- Property management companies (turnovers)
- Real estate agents (pre-listing prep)
- Remodel contractors
Service contract: standing offer to handle final clean at $X/sq ft. Builder books on the schedule.
Common pitfalls
- Underpriced first quote: builder learns your rate; future bids constrained
- Forgetting HEPA: regular vacuum blows fines back into air; customer wipes drywall dust off everything later
- Hot mop on hardwood: warps + ruins finish
- Abrasive on stainless: scratches permanent
- Acid on stone: etches finish
- Walk-through without photos: customer disputes scope
- Crew sees but doesn't note finish work incomplete: re-clean expected free
Customer talking points
For new construction final:
- "Post-construction is intensive: 4-8 hours, 2-3 crew. $X total for [scope]."
- "Includes [list of areas + tasks]."
- "Customer or builder walks through after; address any missed spots."
- "Move-in ready when we leave."
For builder:
- "Per sq ft pricing on a standing basis: $Y/sq ft for final clean."
- "Crew available within 48 hours of your call."
- "Same service quality every house."
Quality control
After every job:
- Crew checklist signed
- Before/after photos
- Customer (or builder) signed satisfaction
- Note any issues for next time
- Crew member assignment tracked
Builders rate cleaning companies. A repeat-customer rate above 80% = success.
The single most-effective marketing for post-construction cleaning: a portfolio of before/after photos of a recent new build. Builders considering you as a vendor want to see your work. A 8-12 photo portfolio shown on a phone closes 60-80% of conversations vs the verbal-only pitch. Track jobs with permission to use photos; build the portfolio over 6-12 months.
