How much does post-construction cleaning cost?

Final clean-up and clearance of the work area runs at B/. 5.00 per m² and disposing of the rubble at an approved landfill at B/. 45.00 per m³. It is the line item most often left out of a budget, and the one that decides whether the job feels finished.

The cleaning line items

The prices on this page come from Gallardía's installation rate card: labour, tools and equipment only. They do not include materials or the ITBMS tax, and they are indicative; the final price is confirmed after a free site visit.

Why post-construction cleaning is not "sweeping up"

A building job leaves three things that domestic cleaning does not resolve: fine cement and plaster dust, bonded residues and heavy rubble.

The fine dust

Plaster and cement dust is microscopic and works its way into window tracks, inside cabinets, into air conditioning grilles and inside light fittings. If you only sweep, everything is grey again in two days because the dust is still airborne and settles slowly. It has to be vacuumed, not swept, and worked from top to bottom.

The bonded residues

Paint splashes, grout residue on tiles, adhesive from labels on glass and aluminium, leftover silicone. Each needs its own technique: grout comes off with product and a sponge, not by scraping — scraping scratches porcelain permanently.

The rubble

This is the part people underestimate. Rubble cannot be left on the pavement or mixed with municipal waste. It has to be hauled and disposed of at an approved landfill, paying the corresponding fee: B/. 45.00 per m³, all in.

To work out your volume: stripping the floor from 30 m² generates around 1 m³. A complete house remodel usually produces between 3 and 6 m³.

The two line items almost everyone forgets

1. Cleaning the roof

When metal sheeting is installed or cut, steel swarf is left on the roof. It looks harmless. It is not: with the first rain it rusts, and that rust runs and stains the new sheeting permanently. Worse, every filing is a point where corrosion starts in the galvanised coating.

Removing swarf and loose fixings is B/. 5.00 per m². On a 90 m² roof that is B/. 450.00 protecting a roof that cost a great deal more.

2. Cleaning gutters, chambers and gullies

During the works everything ends up in the drains: grout, mortar residue, broken tile, screws. If they are not cleaned before handover, the first heavy rain reveals the blockage — and by then the crew has gone.

Gutters and downpipes at B/. 5.00 per metre; inspection chambers and gullies at B/. 20.00 each. It is the cheapest closing check there is.

When to do it

Post-construction cleaning is done once, at the end, when no more trades are coming in. Doing it before the last trade finishes is money thrown away.

What does make sense during the works is daily safety housekeeping: clearing offcuts, keeping walkways free and maintaining order. That is not the final cleaning line item; it is part of working properly and is included in the execution.

For a 120 m² house, a full post-construction clean takes 1 to 2 days with the right crew.

Construction cleaning and maintenance cleaning are not the same

If what you need is recurring cleaning of offices, commercial units, warehouses or common areas, that is a different service and is quoted as a monthly contract, not per m² of works. You can see it on our cleaning page.

Post-construction cleaning is one-off, intensive, and uses techniques and products specific to construction residue. Maintenance cleaning is routine, on an agreed frequency and with a different crew profile.

Related questions

How much does post-construction cleaning cost per square metre?

B/. 5.00 per m² in labour for the final clean-up and clearance of the work area. Rubble disposal is charged separately at B/. 45.00 per m³.

How much rubble does a remodel generate?

As a benchmark, stripping the floor from 30 m² produces around 1 m³. A complete house remodel usually generates between 3 and 6 m³, so between B/. 135.00 and B/. 270.00 of disposal.

Why does the roof need cleaning after installation?

Because steel swarf from cutting the sheeting is left behind. With the first rain it rusts, stains the new roof permanently and starts corrosion in the galvanised coating. Removing it is B/. 5.00 per m².

Can rubble go out with the municipal waste?

No. It must be hauled and disposed of at an approved landfill, paying the corresponding fee. That whole process is B/. 45.00 per m³.

How long does post-construction cleaning of a house take?

1 to 2 days for a 120 m² house, provided it is done at the end, once no more trades are coming in.

Is post-construction cleaning the same as maintenance cleaning?

No. Post-construction is one-off and intensive, using products and techniques for building residue. Maintenance cleaning is recurring and quoted as a monthly contract.
