Our Mission

Our mission is to build a team of skilled professionals and leaders to install waterproofing and building envelope systems at the highest level possible. That means putting our people first – achieving the highest customer satisfaction rating, equipping our employees with the training and equipment to perform well, and valuing our vendor relationships before our own profits.

Our Customers

The basic, guiding principle for GDA contractors is simple: We put our customers’ concerns first. Our ability to perform our best depends on having high-quality customers, so we select our customers from the top commercial construction firms in the country. What’s more, we prioritize quality companies with high expectations and solid values.

Our Team

The quality of our service depends on the quality of our people. Our employees are outfitted and trained with more installation and personal protective equipment than any other firm in our industry. In addition to pre/post-employment health and drug screening, technical training, testing, and weekly safety training, our staff receives product and installation knowledge that gives us an advantage in utilizing developing technologies. We take great care to keep our people trained, safe, happy, and challenged.

Our Suppliers

We rely on our suppliers to continually provide the best materials and equipment for your projects. We install products that are designed, manufactured, and distributed by local and international companies who are as committed to quality, integrity, and service as we are – and we’re committed to their continued success.

OUR CHARITIES

Give to those less fortunate.
We believe in giving back to those that need help and value those that provide for others. We’re grateful for our success and are committed to giving back to the communities that support our business. Some of the wonderful organizations we support include:

The SoupMobile

A faith-based 501(C)3 non-profit organization that feeds and shelters the homeless in Dallas, Texas, the SoupMobile provides over 200,000 meals per year while also providing shelter and sponsoring residences for formerly homeless individuals – including veterans.

What the industry says about us

GDA Contractors are experts in the waterproofing world. Our projects benefit greatly when they are involved in the preconstruction process as they support us by providing valuable constructability and pricing information. During the construction phase, they are a reliable trade partner with a strong focus on schedule and quality. It is always very comforting to know when GDA Contractors is working on our construction projects.

SSI and the GDA companies have worked together over 30 years . We have always valued the good communication and business practices set forward by the management group at GDA. GDA promotes doing a project the right way, not to just get off the job. SSI values the business the GDA companies have shared with us.

Duane Barnett President SSI

Our largest liability on any project is water intrusion. I trust GDA Contractors to provide accurate fair pricing and perform the work correctly every time. Using a quality contractor like GDA provides me a peace of mind on every project they are a part of.

GDA has consistently been raising the bar for the waterproofing industry and for their GC clients, through industry advocacy, sharing of lessons learned, excellent scopes at bid time, and through their informative “Caulktail Hour”s.
