Will a loft survey wake my sleeping baby?

We often conduct surveys in the evenings, and are able to do this very quietly. Our ladders are fibreglass so do not clatter, most loft hatches are plastic and can be opened softly, and in the vast majority of cases our surveyor can take all laser measurements from the ladder without needing even to set foot in the loft. All that remains is to return downstairs to discuss the options with you (sotto voce)… or even just follow up with a call at a later time.
