We serve our maintenance customers who can sign up for any or all these services. You can designate whether you want them provided on weekdays or all days including weekends. We monitor weather throughout the winter and recommend you allow us to make the determination on when to deploy but leave you the option of making the call. We do; however, give priority to those who designate us to make the call. If plowing is desired, we will charge for mobilization when plowable snow is predicted as getting equipment to site must be done prior to the storm. We also provide de-icer pre-treatment but do only if plowing and sanding are also ordered. Pre-treating with de-icer only prevents black ice or heavy frost and is ineffective if snow falls.
