Our Team

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

Measured Performance

Hundreds of past customers attest 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 from 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, Pella, and Andersen Windows, as well as GAF roofing products.



Never Stop Improving

Our team never stops learning and improving. We continually train our team on the latest techniques and provide ongoing education to ensure we exceed industry standards. We meet regularly to review and discuss new products, product changes, and other issues affecting our local market.

Our Team Of Suppliers

Many homeowners are unaware of material suppliers' vital role 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 represents 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 valuable 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.
