There are some columnar crabapple cultivars on the market. Do you know what kind of crabapple it is? 

It looks like your tree could use some pruning on the lower branches but at this point, wait until winter to do that. February through April is the best time, to limit exposure to disease and insects. 

Since it was just planted 3 years ago, you may want to call the landscaper and as for their experience with this tree. 

Newly planted trees can take 3 years to settle in and we have been in a stressful 3 year drought. Keep it well watered and mulch it at the base.
