About Us


Serving the Greater Houston Area Since 1962

A family owned enterprise for five generations, Pfeiffer & Son has a solid history of quality work, fairness, reliability and honesty. Over the decades, this approach to business has been valued by our customers and has enabled the company to grow and prosper to what it is today.

Over 100 certified industrial and commercial electricians, many with specialty certifications and many with long tenure with the firm, enable us to respond quickly to your needs. See the Certified to Do the Job drop-down below for our certifications.

Having on-hand a large and diverse private fleet of trucks and specialty equipment means we always have the right equipment ready to meet your needs. See the Equipped to Do the Job drop-down below to see exactly what we have.

Member of highly respected professional associations:

Pfeiffer & Son promotes the advancement and development of its employees through training and college level education, making the effort to always improve the breadth and depth of its employee knowledge base. We also have many professional and manufacturer certifications in its general and specialty service areas.

Employees are urged to participate in our Department of Labor (DOL) and Texas Department of License and Registration (TDLR) approved Apprentice Training Programs.  These programs are designed to guide individuals that are new to the trade to become fully trained and capable in four years.  We provide a program for electricians and for telecommunications workers.

Another of Pfeiffer & Son’s key assets is our 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.
