When we refer to busy or less busy times, we are talking about the volume of calls. The busiest times are when the most people are calling this Holcim US phone number (least busy times have fewer people calling). This high call volume does not necessarily mean that you will have a long hold time when you call. Companies like Holcim US staff their call centers differently based on the time of day and day of the week, so you may experience a shorter wait on hold at the busiest of times. When we refer to the best time to call, we are referring to the optimal combination of lower call volume and shorter wait times.

The least busy day to call Holcim US is Wednesday. The most busy day to call is Monday. Again, this is based on a sample of 9 calls made with our AI-powered, web-based phone in the last 90 days.

We measured the shortest hold times to be on Monday. The longest wait in the queue on average occurs on Wednesday.
