There are a lot of factors involved in estimating the cost of professional snow removal in Merrimac. Usually, the driveway size has a significant impact on the price. The larger your driveway, the greater the expense of cleaning it. Driveways that are longer and made from gravel could also lead to higher removal costs. Also, if your driveway is exceptionally steep or curvy, it might be costlier to clean. These driveways are harder to clean as compared to standard driveways.
