Our Team

At Home Exterior Systems (HES), we believe with the most profound conviction, that a great company requires a great team of people. For that reason, we continually invest significant time and resources into our already talented group of people. The objective is to strive to be the best possible exterior contracting team in the entire Greater Houston, Texas area.

Measured Performance

Hundreds of past customers attest to the fact that HES has unsurpassed sales, project management, support, and installer team members. This fact reflects the consistently high marks (95 % or more out of 100) in our regular Guild Quality independent surveys.


The collective experience within Home Exterior Systems is staggering. The combined experience of all the team members reflects more than a century of know-how at your service. We rarely see something for the first time, and we know all the local best practices by heart.

Houston’s climate is brutal and very different than much of the country. Our installers are locally trained and recognized experts by our material manufacturers like James Hardie Siding products, Sherwin Williams Paint, Simonton Windows, and GAF roofing.



Never Stop Improving

The entire team never stops learning and improving. We are continually training our team on the latest techniques and providing ongoing education to ensure we are exceeding industry standards.

Our Team Of Suppliers

Many homeowners are unaware of the vital role material suppliers play in their home renovation projects. HES strives to be the customer everyone wants to have every single day. Having great supply-chain relationships means a lot of things, but most importantly, it means excellent relationships and open communication. HES believes we have among the very best materials supplier partners in the country. That translates to more reliability and on-time performance, among other useful things.


Thank you for considering Home Exterior Systems! We look forward to demonstrating why we believe you should choose HES for your exterior home project. You won’t regret it.



Meet the Owners

Meet the Owners


If ever there was a multi-hat donning voice to HES, it’s co-owner Vicky McCollim. Nearly all customers speak with her at some point in her oversight of all customer, and vendor, relations. With over 15 years in the home improvement field, the down-to-earth Vicky has a keen understanding of the business, and how to help people get what they want without frustration. Even as busy as she is, her growing family, and her faith, are always a very high priority. Her many talents include home decorating, and cooking – affectionately called “the sandwich magician.”


Patrick “Pat” McCollim is co-owner of HES, wearing many hats including the President and CFO. Pat brings a high level of sophistication and leadership, rare in the remodeling world, honed over three decades in finance and new business development for one of the largest companies in the world. He sees great opportunities for customers to get the best possible results, value, and overall satisfaction by focusing on, and measuring, what’s important to them.  Driven by his family, his faith, and the overwhelming desire to do things right, Pat refuses to settle for less than excellence in all things.


HES Partner & Co-owner Caleb McCollim has a degree in Finance and has used his education in an eclectic mix of opportunities. He spent four years abroad teaching Business English at a premier University in Beijing, China. Caleb has had the privilege to travel to 5 continents and over two dozen different countries and experience many diverse cultures. He brings unique knowledge and perspective of customer service dedicated to excellence to our team. He has developed the art of listening to his customers, which results in connecting customers with the right finished product. We are proud to have him as a member of our team.

True Caring Craftsman

We've sprayed, rolled, and brushed thousands of gallons of Sherwin Williams paint upon tens of thousands of linear feet of James Hardie siding that we installed on hundreds of Houston area homes. 

We're no slouch at the rest of the home exterior renovation either having replaced Windows and roofing on hundreds of our neighbors' homes too.

There is no better team available, anywhere, at any price than this Home Exterior Systems group.
