Our work
Real homes, real neighbors
We are experts in custom builds, whole home remodeling, build management, new homes, and preconstruction planning. We have got you covered – proven for years.
How we work at Flenn Custom Homes & Remodeling
From first conversation to finished home.
Four steps, one builder in the field the whole way. A collaborative preconstruction process aligns the design with what you actually want, and the construction phase delivers it with precision and craftsmanship.
01
Listen & discover
We start on site, not on paper. We walk the space, ask how your family actually lives, and get clear on goals, must-haves, and a realistic budget range before anything is drawn.
02
Design & select
Collaborative preconstruction: plans, layouts, and finish selections worked out together, so the design matches what you pictured and what the site allows before a single wall moves.
03
Formal estimate
A detailed, line-item estimate built on more than 40 years of construction experience.
04
Build & hand over
One accountable crew, tidy job sites, and Greg in the field. Precision and craftsmanship through the final walkthrough, then a lifetime warranty on our workmanship.
You work with the same builder from the first walkthrough to the last punch-list item, and every project is backed by our lifetime workmanship warranty.
Our promise
Backed for life.
A lifetime craftsmanship warranty on every project we build.
“We provide a lifetime guarantee on the quality of our craftsmanship. If any issue ever arises from the work we performed, we come back and make it right. Promptly, and professionally.“

95% of our work comes from referrals
About 95% of Flenn Custom Homes & Remodeling projects come from repeat clients, neighbors, and trade partners who recommend Greg Flenniken by name across Georgetown, Cedar Park, and the greater Austin area. Most of our homeowners found us the same way, someone they trust had us in their house first.
Working With Him Was A Breeze. Just When I Thought Things Were Getting tough, Greg Was There To Help To Get The Job Done.
Respectful, Patient, Prepared, And Just A Great Character In General.
I Wish More Contractors Could Operate The Way Flenn Custom Homes Does .
I Look Forward To Working With Greg In The Future.
Thanks For Every Thing !!!
I would also like to add: we have only ever done small remodeling jobs on our homes never a complete remodel and design. I was NOT looking forward to this project in any way!
Greg Flenniken was such a huge help with his encouragement keeping me on schedule even when I was at my worst. Greg is a man of integrity and moral character. Bringing that to the table combined with his years of experience completes a beautiful home that brings years of enjoyment to the home owner.
Even though we were out of town for most of our last remodel, he finished on time and on budget. I would recommend Flenn Custom Homes to anyone looking for a builder they can trust with the home if their dreams.
Greg is a perfectionist, and he takes personal responsibility for making sure the work is done to a high standard of quality. He was always available during the project if we had a question or request; and he promptly stopped by to discuss these with us. Greg also suggested several ways we could save money without sacrificing the features and design we wanted.
We're delighted with our home and are planning to stay here a while; but if we're ever looking to remodel or build a new house, we'll call Greg Flenniken.
Reviews are from verified Google reviews by homeowners in Williamson and Travis County. Ask us for references on a project like yours, we’ll connect you with past clients directly.
