    "I strongly recommend Drenckhahn Excavating for any project where one needs an excellent excavating contractor. They are excellent at what they do because of their deep-seeded knowledge about the process. On top of this, they are punctual, remain on schedule, and stay until the work is completed. There are no unnecessary “extras.” Besides Drenckhahn’s excavating skills, I started using them to do the base for my driveways and also do all the grading, rough and finish, for my projects. I also have them install all my septic systems because they do a much better installation than the so-called typical septic system subcontractors, and also because it’s a snap to manage everything under one subcontractor."

    "I am pleased to write a letter of recommendation for your firm, having worked with the team as both a general contractor, developer, and architect.

    There are few subcontractors that put me at ease when I arrive on a jobsite quite like Drenckhahn Excavating. No sub-contractor pushes the job schedule quite like yours, and none do it with the same blended concerns of schedule, quality and safety.

    There are numerous things that a builder and or project manager will consider when choosing a sub contractor: honesty, integrity, knowledge, punctuality, competitiveness, performance and on time delivery.

    Drenckhahn Excavating has all of the above and more.
