"This past July, my father and I did a project on my concrete driveway and sidewalks by installing the Trim-a-Slab 3/4 expansion joints. I originally saw this brand online through the Lowe's Website, but I saw that it was going to take a week for the product to arrive. I then did some research and I ordered their test kit directly from their website to decided what size to go with. After I have decided what size to go with from their test kit, I then realized that their warehouse was located outside of Houston and I live 48 minutes away from their location, so I decided to buy their product directly in-person from their Warehouse instead of ordering at Lowe's since Lowe's only sells it online. I bought four 50 feet of 3/4 expansion joints. It's been 2 months since I have installed the Trim-A-Slab product on our concrete and I have been extremely satisfied with their product. We previously had wooden expansion joints, but the problem with wood is that it deteriorates over time and weeds grow on the wood during the summer months. With Trim-A-Slab, their expansion joint has prevented weeds from growing between the concrete and has provided a better appeal on our sidewalks and driveway. Overall, I am happy with their product. I definitely suggest Trim-A-Slab if you are looking to replace the expansion joints between a concrete."

"Friendly and helpful customer service! Ordered the sampler first to make sure of correct size. Quality product made in Texas (not like the stuff from China). Easy to install. Finished job looks great. I recommend this company and its product."

"Absolutely wonderful product but even better a wonderful company with service above and beyond. First of all the trim a slab is terrific, easy to install and looks great. I even had a problem with my second order and received some of the wrong size. I contacted them directly and they fixed it no questions asked. Not only did they fix it but they somehow had the right stuff delivered the very next morning to my home. Now THAT is how to deliver on a customer service promise. BRILLIANT. Thank you Trim a Slab"

"This a great, Houston-area made product that is SO much easier than caulking. It obviously costs more, but was a better value for me because I would have to hire someone to caulk all the gaps that needed it. And you get a discount when you pick it up directly from the manufacturer!"
- Leslie Sosebee
"Great product, and great explanation of instructions on how to measure so that you order the correct product. Just placed another order for a different size, shipping is petty quick. I definitely recommend this company."
- Wayne Cramer
"I received the trim a slab yesterday, I’ve had a problem with the wood rotting out, so I did some research, found the trim a slab. I removed the rotted wood, and just replaced it with your product. It fit perfectly. I’m telling my friends about this."
- Terry Jirtle
"I highly recommend using Trim a Slab to fill in your driveway expansion joints. Their customer service was top notch, the product was a breeze to install, and it looks great. Of all of the options I researched, Trim a Slab appeared to be the easiest to install and it really was. I had the privilege of stopping in to their store and they gave me a free sample pack, a free cutter, and a discount. The most difficult part of the work was removing the old wood. If I need to fill anymore expansion joints I will definitely use Trim a Slab again."
- Joe P
"I purchased the sample kit which was ideal in helping me determine the exact size I needed. I only wanted to replace 12ft of expansion joint in my driveway. Jacob sold me the exact amount I needed rather than me having to purchase the entire 25ft roll. I drove to his shop to pick up the material. The install was even easier than I hoped and it looks great! I YouTubed the various methods out there and boy am I glad I decided to go with Trim-a-Slab. Great customer service and a fantastic product. Home Depot/Lowes, you need to carry this item!!! "
