Built on Experience and Trust

Since 2014, Brothers Supply has partnered with custom home builders across Texas to deliver quality products and unmatched service.

Brothers Supply Company

Our Story

Brothers Supply Company was founded in 2014 by Mark Lawing, after more than 30 years of experience supplying windows, doors, hardware, and fireplaces to custom homebuilders. With two elders from his church as partners, Mark started the company with a simple goal: to serve builders with honesty, expertise, and reliability.

In 2017, Chris Haga joined the team, bringing over 15 years of retail management experience. By 2019, he became a partner, helping Brothers Supply grow while keeping the same values at the center — responsiveness, integrity, and builder-first service.

Who We Serve

Our customers are custom homebuilders and remodelers who want more than just a product drop-off. They come to us because:

Quotes are turned around quickly — often within 24 hours.
Our in-house service team handles issues directly, instead of passing them off to manufacturers.
We recommend products that balance performance, design, and budget.
When something goes wrong, we don’t hide — we solve it.

This approach has earned us steady growth without advertising. Our business has been built almost entirely on word-of-mouth referrals from builders who trust us to deliver.

Our Commitment

Work With a Team That Puts Builders First

We don’t measure success just by what we sell, but by the relationships we build. Every product we supply — from windows and doors to fireplaces and hardware — comes with the promise that we’ll stand by the builder and the homeowner until the job is done right.
