Other than don't...! We did actually move out for 3 months while the worst was done, but having to move back in with around another 2 months of building work to go... I have heard a couple of good tips, eg use cold water not hot for builders dust / only unpack absolute essentials to save additional dusting... Anything else? We are having kitchen, bathroom renovations plus attic conversion (re-plumbing, re-wiring and new windows done). Thank you!
