The most useful after builders cleaning tips for cleaners come down to what you check before you agree to the job, not what you do once you arrive. Post-renovation work is a different job to a standard clean: there is more dust, it settles into places a normal clean never touches, and a property can look far worse in person than a few phone photos suggested. Look at the space first if you can, ask specific questions about the type of work that was done, and price for the extra time fine dust genuinely takes to clear before you say yes.
Assessing the job before you quote
Ask what kind of building work happened, not just that "building work" happened. Plastering, sanding and cutting tile, block or concrete throw off much finer, more persistent dust than a repainted room or new flooring. Find out whether the site has had any tidy-up already, whether rubble and offcuts have been cleared, and whether it is one room or the whole house. A quick video call or set of close-up photos of the dustiest surfaces, a windowsill or the top of a radiator, tells you more than a general description of "a bit dusty."
After builders cleaning tips for cleaners: a pre-job checklist
- Confirm exactly which rooms are included and whether any areas still have trades working in them.
- Ask whether rubble, offcuts and packaging have been removed, since builders' waste removal usually is not a cleaner's job.
- Check what surfaces were affected: ceilings and walls mean a slower, top-to-bottom job compared with floors alone.
- Confirm access to water, power and somewhere to empty a mop bucket before the day itself.
- Bring or confirm a vacuum with a sealed filter; a normal domestic vacuum can push fine dust straight back into the air.
- Pack a dust mask, gloves and eye protection rather than assuming the client will have any on site.
- Agree what happens, and what it costs, if the property is dustier than described once you arrive.
Agreeing price and scope before you start
After builders jobs are one of the easiest to underprice, because the mess is often worse than it looks from outside a room. Quote a time range rather than a fixed hour count where you can, and be clear that a heavier-than-described job may need a second visit or a higher price. Our guide on how to price cleaning jobs in Ireland covers hourly versus fixed pricing in more detail if you are still settling on a rate. It also helps to agree upfront who is responsible for anything found broken or already damaged from the building work, since that is not something a cleaner should be expected to fix or replace.
Protecting yourself from dust and chemical risks
Fine dust from cutting, drilling or grinding concrete, stone or brick, known as respirable crystalline silica, is invisible to the eye and can stay suspended in the air for hours after the work stops, according to the Health and Safety Authority. Repeated exposure over time is linked to silicosis, a lung disease, along with other serious respiratory illness, so treating "just dust" as harmless is a mistake worth avoiding. A well-fitted FFP3 mask, built to the EN 149:2001 filtering standard, blocks the large majority of fine airborne particles and is worth the small extra cost over a basic dust mask for anything beyond light sanding dust. Ventilate the room before you start moving dust around, work from ceiling height down to the floor, and take breaks somewhere free of dust if you are covering more than one heavily affected room in a day.
Insurance and self-employed basics worth sorting first
Working as an independent cleaner in Ireland generally makes you a sole trader, and Citizens Information is clear that there is no legal requirement to hold business insurance as a sole trader. That said, it also advises getting public liability cover once your work regularly brings you onto someone else's property, which after builders jobs certainly do: a knock to a newly plastered wall or a scratch on new flooring is a real risk on a job like this. If you have not registered for tax as self-employed yet, our guide on finding cleaning jobs in Ireland walks through registering with Revenue as a sole trader.
Kit worth having for this job type
A sealed-filter vacuum, microfibre cloths in enough quantity that you are not reusing a dust-caked one, a mop and bucket you can change water in often, and basic PPE cover most after builders jobs. Our cleaning supplies checklist for cleaners starting out lists what is worth buying first if you have not built up this kit yet. Keep a separate set of cloths for this kind of job where possible; dust-heavy cloths are hard to fully clean and are better kept apart from the ones used on ordinary weekly cleans.
