Cleaning after an extension
A clean after an extension costs €400 to €600 for the new part and the rooms next to it, and takes most of a day. If the dust has spread through the house, price a builders clean of the whole home instead: €350 to €700 for a three-bed.
The new part, its glazing and the rooms beside it, and when the dust has spread further.

- €350–€700the whole three-bed house
- 1 dayfor most extensions
- Glassdoors, rooflights and frames take longest
Where the time goes
- Glazing. Sliding and folding doors have tracks full of grit, rooflights need cleaning from inside, and every frame has film to peel.
- A new kitchen. Sawdust inside every unit and drawer, film and labels on the appliances, the hob and the oven.
- New floors. Grout haze on new tiles, or a timber floor that wants only a barely damp mop.
- The knock-through. Where the old house opens into the new part, dust has spread into the rooms beside it.
Peel the film early
Window and door frames arrive wrapped in protective film. Left in the sun for months, it bakes on and comes off in shreds, and scraping it costs time. Peel it as soon as the plastering and painting near the frames are done.

Plan your after builders clean
A few quick taps: the clean your job needs, what it costs and how long it takes. Contact details come last, and only if you want a fixed price.

How the estimate is worked out
The ranges are what Irish cleaning companies charge for the same clean: the lowest to the highest figure for a home of that size, or per m² for a commercial unit. A smaller home's three-stage clean is its builders clean plus a sparkle clean. Use it to plan with: the company fixes the price after seeing the job or photos of it.
Which clean does your job need?
Each clean has its own page: what it covers, what it costs and when to book it. Commercial units: commercial builders cleaning.
New build cleaningFrom building site to move-in day, usually in three stages.

How much does it cost to clean after an extension?
€400 to €600 for the extension and the rooms beside it, or €350 to €700 for the whole three-bed house.
Do I need the whole house cleaned after an extension?
Often only the extension and the rooms beside it. If the knock-through was done with the house open, the dust usually reached the rest.
How do I get protective film off window frames?
Peel it as soon as the work near the frames is done. Film left in the sun for months bakes on and needs careful scraping.
