The St. Louis & Metro East Region

St. Louis Basement Waterproofing and Foundation Repair

At Helitech, we pride ourselves on being founded on humble beginnings. Helitech’s main office is the once childhood home to owner and founder, Mr. William Courtney. Mr. Courtney grew up the son of a farmer on the grounds of the now-turned office right outside of Downtown St. Louis.

Even though many changes have been made over the years, there are still many similarities on the grounds. What once was a living room for the Courtney family to gather is now a conference room for the Helitech family to meet. The kitchen area has been updated some, but overall remains the same. The once machine shed for tractors and combines still serves much of the same purpose now as a garage for Helitech’s trucks and equipment.

However, the most important thing that has remained throughout the years is hard work and a sense of family each employee shares. Every other month, we put together a company newsletter with Q&A section for employees. The number one answer to “What is your favorite thing about working for Helitech” has been “the people”.
