A building site you would rather not enter is a site you cannot check. That is why AIGNER BAU has a fixed rule: the site is completely tidied and cleaned every working day before the team leaves.
For us, cleanliness is not an extra and not a final clean at the end. It is the visible part of how we work: the way the site looks is the way we work behind the walls.
Before the team leaves the site, it is swept clean: tools put away, rubble removed, floors swept. Every working day, without exception.
Dust barriers, covers and protective sheeting for adjoining rooms, the stairwell and the neighbours. We treat your property as if it were our own.
After a short arrangement with us you can see how the work is going on site. When work begins, responsibility for site safety passes to us. If you work cleanly, you have nothing to hide.
You always know which trade is working, what is done and what comes next. No surprises on site, none on the invoice.
Arrange a no-obligation initial consultation. We come for a site visit, calculate transparently and give you your fixed price.
