Drywall FAQ

What's the difference between Type X and Type C drywall?
Type X is 5/8" fire-rated drywall that meets code for 1-hour fire assemblies — required in garages, stairwells, and most commercial applications. Type C is an enhanced version with additional glass fiber reinforcement, providing better performance during a fire (it expands slightly as it heats, maintaining the assembly). Type C is typically specified for 2-hour assemblies or higher-rated commercial builds.
Do you carry moisture-resistant drywall for Houston's humidity?
Yes — and it's one of our most requested products for good reason. Houston's climate makes standard drywall a liability in bathrooms, kitchens, laundry rooms, and any space near exterior walls. We stock USG Mold Tough, Gold Bond mold-resistant, and paperless/fiberglass-mat board options. Call us and we'll match the right product to your application.
Can I get contractor pricing without a contractor account?
For one-time purchases, call us with your quantities and job details — we can often work with you on pricing for large orders. For ongoing contractor work, opening an account gets you bid pricing, priority stock, and faster checkout. Setting up an account takes 5 minutes. Call (281) 741-3588 or fill out the contact form and we'll get you set up.
What sheet sizes do you stock?
We regularly stock 4x8, 4x10, and 4x12 sheets across most product types. 4x8 is our highest-volume size and almost always available same-day. 4x10 and 4x12 are available with a short lead time for larger orders. Call ahead if you need a specific size in quantity and we'll make sure it's ready.
Do you deliver, or is it pickup only?
Both options are available. Same-day pickup in Houston is available for orders placed before noon. Delivery is available to Houston and surrounding areas — call us at (281) 741-3588 to discuss your delivery needs and we'll work out the logistics.
