Quick answer
Construction handover cleaning in Ireland typically runs in three cycles: builders' clean (rough-clean during construction phase, focused on debris and dust), sparkle clean (deep clean to a snag-tolerable finish, typically 2-4 weeks before practical completion), and final clean (post-snagging refresh just before client handover). Pricing is per-square-metre or fixed-price by floor count and finishing standard. HSA Safe Pass and PSCS coordination apply throughout.
What are the three handover cleaning cycles?
1. Builders' clean
Builders' clean (sometimes called “first clean” or “rough clean”) is performed during or immediately after the construction phase. Scope:
- Removal of bulk debris, off-cuts, packaging, and loose construction waste.
- Sweep of all surfaces.
- HEPA-filtered vacuum or wet-sweep of slabs and stairs.
- Tape-residue and label removal from surfaces (windows, fittings, doors, sanitaryware).
- Site protection materials (corex, hardboard) lifted, sorted, and removed.
- Stickers and protective film removed from window glass, sanitaryware, kitchen units, and ironmongery.
- Dust removal from elevated surfaces (door tops, ledge, beams, vents).
- Initial floor wash where the floor finish is installed.
- Bin and skip clearance.
Builders' clean is not a finished standard — it is the preparation for sparkle clean. Plaster splatters, paint marks, and residual dust may remain.
2. Sparkle clean
Sparkle clean (sometimes “final clean” in some specifications, “deep clean” in others) takes the building to a snag-tolerable presentation finish. Typically scheduled 2-4 weeks before practical completion. Scope:
- Full deep clean of all surfaces — horizontal and vertical.
- Glass: every window, including frames, sills, and reveals; mirrors; glazed partitions.
- Sanitaryware: WCs, basins, taps, showers, baths fully cleaned, descaled, polished.
- Kitchen units: fronts, interiors, work surfaces, sink, taps; appliance exteriors and interiors where present.
- Ironmongery: door handles, hinges, locks, push-plates polished; fingerprints removed from stainless and chrome.
- Floor: appropriate finish — vinyl strip and reseal, stone polish, timber polish, ceramic detail.
- Plaster splatters, paint splashes, and silicone overspray removed.
- HVAC vents and grilles cleaned.
- Light fittings dusted; lamp surfaces wiped.
- Skirting boards detailed.
- Door surfaces and frames degreased and polished.
- External surfaces (lobby glass, entrance hardware) polished.
The sparkle-clean output is the standard against which the snagging walk is conducted — finished, clean, and presentable, but with snag items (paint chips, sealant gaps, alignment issues) outstanding for the principal contractor to correct.
3. Final clean (post-snagging)
After snagging by the contractor and any repaired works, a final clean refreshes affected areas before client handover. Scope:
- Re-clean of areas where snagging works generated dust or marks.
- Final touch-up of high-use areas (entrance, reception, lifts).
- Final WC and kitchen check.
- Final floor refresh.
- Visual sign-off with the client representative.
How does this align with RIBA Plan of Work stage 6?
Although the RIBA Plan of Work is a UK reference, it is widely used by Irish architects and contractors. Stage 6 (Handover) covers the period from practical completion to occupation. Cleaning aligns to Stage 6 broadly as:
- Stage 5 (Manufacturing and Construction): builders' clean cycles run in parallel.
- Stage 5 to 6 transition: sparkle clean runs in the 2-4 weeks before practical completion.
- Stage 6 (Handover): final clean runs after snagging and immediately before client occupation.
What is a snag-tolerable surface condition?
A snag-tolerable surface is one where: the surface is clean enough that any defect visible is a defect of the construction work itself, not residual cleaning issue. The snagging surveyor (architect, employer's representative, or client) should be able to assess the work without having to mentally subtract dust, splatter, or residue.
Specifically:
- No paint splatter on glass, hardware, sanitaryware, or floor.
- No silicone overspray on adjacent surfaces.
- No protective tape residue — tape and adhesive residue fully removed.
- No plaster dust on horizontal or vertical surfaces.
- No sticker remaining on glass, kitchen units, or hardware.
- No fingerprint or smudge on glass, mirrors, or polished hardware.
- No water spotting on stainless or chrome.
- No grout haze on tiled surfaces.
What do main contractors commonly miss?
The areas where handover cleaning frequently falls short:
- Light fittings and lamp surfaces: dust on glass shades; bug residue inside enclosed fittings.
- HVAC grilles and vents: white powder dust; visible from below in occupied spaces.
- Window reveals and sills: corner accumulation of plaster dust.
- Door tops: dust accumulation only visible from a stepladder.
- Skirting board top edge: dust ledge.
- Inside kitchen unit drawers and cupboards: factory protective film residue and dust.
- Inside dishwasher / oven / fridge: factory protective film and packaging residue.
- Behind sanitaryware: dust accumulation between WC and wall.
- Sealant joints: smudges or excess sealant overspray.
- Glazing manifestation tape residue: where dot-and-dash or branding has been applied during construction and removed.
How does dust mitigation interact with HVAC commissioning?
HVAC commissioning typically requires the building to be at a near-finished standard before air-handling units, fan coils, and VRV systems are switched on. Dust ingested into the system at start-up can damage filters, blow into freshly-painted areas, and require post-commissioning recommissioning at significant cost.
Cleaning sequence for dust-sensitive HVAC commissioning:
- Builders' clean of all areas before HVAC commissioning starts.
- HEPA-filtered vacuum of slabs, ceiling voids, and plant rooms.
- Filter check on commissioning units.
- Sparkle clean of all areas while HVAC is running.
- Filter change after sparkle clean if filter loading detected.
- Final clean and filter check before occupation.
What about glazing and floor protection during cleaning?
- Glazing protection film: should be removed by the contractor before sparkle clean, but residue is common. Tape-residue removal is part of sparkle-clean scope.
- Floor protection (corex, hardboard, dust sheets): lifted during builders' clean. The exposed floor is then deep-cleaned during sparkle clean.
- Furniture and FF&E protection: where furniture has been delivered before final clean, protection wrapping is removed by the contractor or installer; cleaning contractor cleans newly exposed surfaces.
Who pays for handover cleaning — the main contractor or the client?
Standard practice in Irish construction:
- Builders' clean and sparkle clean: the main contractor's cost, included in the contract price. The contractor either deploys their own labour, sub-contracts to a specialist cleaning company, or uses the construction trades on overtime. Specialist sub-contracting is the norm for high-spec finishes (hotels, healthcare, premium offices).
- Final clean (post-snagging): also typically the contractor's cost.
- Initial occupation cleaning (post-handover): usually the client's cost — this is when ongoing FM cleaning takes over.
Disputes arise when sparkle-clean scope and final-clean scope are not defined explicitly in the contract, leaving the client and contractor disagreeing on what was supposed to be delivered.
What does a handover cleaning specification cover?
A defensible specification covers:
- Number and timing of builders'-clean cycles during construction.
- Sparkle-clean scope (typically a long task list by area type).
- Sparkle-clean scheduling (typically 2-4 weeks before practical completion).
- Final clean post-snagging.
- Standard of finish (snag-tolerable; specific surface-by-surface criteria).
- Compliance: Safe Pass, manual handling, COSHH, PPE, public liability and employer's liability insurance.
- PSCS coordination protocol.
- Working hours and access during construction phase.
- Reporting: daily progress, exception log, completion sign-off.
- Pricing: per-square-metre or fixed-price by area; ad-hoc rate for additional cycles.

How is handover cleaning priced in Ireland?
- Per square metre: typical for sparkle clean; rates depend on finish quality and floor count.
- Fixed price by floor count and area type: typical for residential apartment buildings or repeat-typology projects.
- Hourly rate: typical for builders' clean cycles and ad-hoc additional work.
The 2026 ERO operative floor is €13.30/hr; sparkle-clean operatives often command above this because of the precision skill required. We do not publish specific euro figures here because they vary materially by project type, finish quality, and county.

Frequently Asked Questions
What is the difference between builders' clean and sparkle clean?
Builders' clean is rough cleaning during or immediately after the construction phase: bulk debris removal, sweep, tape-residue removal, sticker removal, surface dusting. Sparkle clean is the deep clean that brings the building to a snag-tolerable finish: full surface clean, glass detail, sanitaryware polish, ironmongery polish, floor finish, HVAC grille clean. The two are sequential, not alternatives.
When should sparkle clean be scheduled?
Typically 2-4 weeks before practical completion. Scheduling earlier risks the building accumulating dust again before handover; scheduling later risks running out of time to complete the snagging walk and remediation. The exact timing is set in coordination with the main contractor's programme and the snagging schedule.
What does a snag-tolerable surface mean?
A surface clean enough that any defect visible is a defect of the construction work itself, not residual cleaning issue. No paint splatter, no silicone overspray, no protective tape residue, no plaster dust, no stickers, no fingerprints, no water spotting, no grout haze. The snagging surveyor should be able to assess work without mentally subtracting cleaning issues.
Who pays for sparkle clean?
Standard Irish construction practice: the main contractor pays for builders' clean, sparkle clean, and final clean as part of the contract price. The cleaning is either delivered by the contractor's own labour, sub-contracted to a specialist, or covered by trades on overtime. Disputes arise when scope is not defined explicitly in the contract.
How does HVAC commissioning interact with handover cleaning?
HVAC commissioning typically requires the building at near-finished standard before air handling units, fan coils, and VRV systems start. Dust ingested at start-up damages filters and blows into freshly-painted areas. The sequence is: builders' clean before HVAC start; HEPA vacuum of plant rooms and ceiling voids; HVAC commissioning; sparkle clean; filter check and possible filter change; final clean.
What surfaces are commonly missed in handover cleans?
Light fittings (especially enclosed fittings with bug residue inside); HVAC grilles (white powder dust visible from below); window reveals and sills (corner plaster-dust accumulation); door tops (dust ledge only visible from a stepladder); skirting top edges; inside kitchen drawers (factory film residue); inside appliances; behind sanitaryware; sealant joints; glazing manifestation tape residue.
Do sparkle-clean operatives need Safe Pass?
Yes if working on a live construction site — Safe Pass is mandatory for any operative on a construction site under S.I. 291/2013. If the site has reached practical completion and is no longer a construction site, Safe Pass is no longer required for the final-clean cycle, though many cleaning companies maintain the qualification anyway.
How is sparkle clean priced?
Typically per square metre, with rates depending on finish quality and floor count, or as a fixed price by floor count and area type for repeat-typology projects (apartment buildings, hotels). Hourly rate is typical for builders' clean cycles and ad-hoc additional work. Sparkle-clean operatives typically command above the basic ERO operative floor rate because of the precision skill required.
What is the difference between sparkle clean and final clean?
Sparkle clean takes the building to snag-tolerable presentation finish, typically 2-4 weeks before practical completion. Final clean is the post-snagging refresh of areas affected by remediation works, immediately before client handover. Both are typically the contractor's cost.
Should the client commission their own handover clean?
Generally no — handover cleaning is the main contractor's responsibility under standard Irish construction contracts. Some clients choose to commission an independent “arrival clean” or “move-in clean” just before occupation, particularly for offices where furniture is being installed and accumulating dust during installation.
How is dust mitigation handled for occupied buildings adjacent to construction?
Where the construction site is in or adjacent to an occupied building (refurbishment, fit-out, extension), the cleaning contractor handles dust-barrier hoarding cleaning on the occupied side, daily wipe-down of the affected interface, HEPA-filtered vacuum cleaning of occupied areas, and adjacent-property cleaning at the working-site interface. See our construction site daily cleaning guide for details.
