Frost Lumber Co Inc is a family-owned lumber and building supply company located in Thibodaux, Louisiana. 

We carry a full range of structural, exterior, and interior building materials serving homeowners, 

contractors, and builders across South Louisiana.

Since 1882. That's over 140 years of continuous operation right here in Thibodaux, Lafourche Parish. 

Five generations of the Frost family have kept the doors open, the shelves stocked, and the community served.

We serve a wide range of customers - licensed contractors and commercial builders, homeowners tackling 

weekend projects, people doing storm repairs, and everyone in between. 

If you build, fix, or maintain anything in South Louisiana, you'll find what you need here.

When you walk in here, you're talking to people who know lumber, know Louisiana, and know you by name after a couple of visits. 

We don't have automated kiosks or an 800 number. We have real people with real experience who can help you figure out exactly what your project needs.

That's a big part of what we do. Bring your plans, your dimensions, your photos, or just your description - and we'll help you figure out what you need and how much of it to get. 

We've been answering those questions for a long time.

Yes. We supply materials for everything from single-family home repairs to large commercial and contractor builds. 

Our inventory is deep enough to support projects of all sizes, and we're experienced in both.

Reliability, inventory depth, and people who actually know the product. 

Contractors come back to us because we're consistent, we're local, and we've been here long enough that our word means something. No surprises, no runaround.

We do. While our roots go back to 1882, our inventory reflects what's being built today. 

We stay current on materials, building codes relevant to Louisiana, and products that perform in our climate.

A real welcome. You'll walk into a full-scale lumber and building supply operation - a full city block of inventory - and you'll find someone ready to help you right away. 

We're located at 511 W 7th St in Thibodaux, and we're open Monday through Friday starting at 6:30 in the morning and 7am - noon on Saturday.  Sunday we rest.

By showing up the same way every time. 

We know our customers, we remember their projects, and we're here when they need us. 

That's how you stay in business for five generations.

Absolutely. South Louisiana's heat, humidity, and storm exposure require materials that can hold up. 

We stock with that in mind - and our team can point you toward products that are proven performers in this climate.

Of course. You don't have to know what you're doing to walk in here. 

Tell us what you're trying to accomplish and we'll help you figure out the rest. 

That's how it's always worked.

Yes. We carry materials for everything from major new construction to small repairs and maintenance jobs. 

Whatever brought you in, we've likely got what you need.  If not, we'll gladly order it for you.

We've been in this business long enough to know which products hold up and which don't. 

Our buying decisions are based on performance, not just price, and our team stands behind what we stock.

Yes - and we do it the old fashioned way, on a human-operated machine. No self-service kiosk, no guessing.
