Equipped to Do the Job

Another of Pfeiffer & Son’s key assets is its equipment fleet.  Because of our size and the varied and diverse types of work we do, Pfeiffer & Son is able to efficiently and consistently employ its equipment across all the different fields and industries in which it works (even those in which such equipment is traditionally not used or that would normally be rented at a costly rate by smaller contractors).  Having such a diverse array of equipment available lowers job costs and increases job productivity and quality.
