TESTIMONIALS

Our Happy Customers

Ozzy O
★★★★★
After my Amazon order of glass block was destroyed, a quick google search brought up Quality Glass Block. Figured it was worth a shot as glass block is not stocked in the big box stores and the masonry companies charged outrageous prices per block here in CO. First, their packaging was excellent to ensure no damage during shipping and you could see the care they put in by packaging to ensure no damage. Second, their prices were better than anywhere I could find on the front range which more than covered the shipping cost. Third, shipping was relatively quick, ordered on Friday and received the next week. Excellent job on email updates with order information and tracking.

I will only use Quality Glass Block from now on for any of my jobs. I highly recommend Quality Glass Block.
Devon Leichtman
★★★★★
I ordered 75 glass blocks at roughly 10pm on a Tuesday night. Since Quality Glass Block offers free delivery in the Chicagoland area for orders over $150, it was by far the best deal I could find online.

I expected to receive the blocks maybe a week down the road, normal shipping time. Nope! I get a call the very next morning, not even 12 hours after I ordered, saying they would be in my area and could deliver the blocks that day. They were incredibly receptive to my instructions for the delivery, and dropped the blocks off around noon on Wednesday.

If you're in or around Chicago, there is literally no reason to go to Lowe's, Home Depot, etc. for glass blocks. Maybe the speed at which mine showed up is an outlier, but these guys are legit.

FAQs

Is there a minimum order quantity?

We have no minimum order at Quality Glass Block.  Order what you need.

When will my order ship?

In stock orders typically ship in 1-2 business days from time of order to ship.

Are glass blocks load bearing?

All glass blocks are not load bearing.  A lentil or header must be used in an opening to support the wall material above the glass block.

What is the difference between actual size and nominal size with Imperial size blocks?

Actual size denotes the measurement of the block by itself where as nominal size denotes the block size with a ¼” mortar joint.

What is the difference between Imperial sizing and Metric sizing?

Imperial sizing is ¼” smaller than the nominal size listed.  Metric size block are actually measured in millimeters and are usually smaller than the Imperial size blocks.
