Happy Easter from Aggtrans
'Now after the Sabbath, as it began to dawn toward the first day of the week, Mary Magdalene and the other Mary came to look at the grave. And behold, a severe earthquake had occurred, for an angel of the Lord descended from heaven and came and rolled away the stone and sat upon it. And his appearance was like lightning, and his clothing as white as snow. The guards shook for fear of him and became like dead men. The angel said to the women, “Do not be afraid; for I know that you are looking for Jesus who has been crucified. He is not here, for He has risen, just as He said. Come, see the place where He was lying. ' Matthew 28:1-6 https://www.bible.com/bible/100/MAT.28.1-6.NASB1995

What Our Customers Say

“The job is still pending. I can let you know more later part of next week. I do appreciate your quote, and used your company a few weeks ago for a large backfill project in southeast DC. Your company was great and helped the job go smoothly. AggTrans will be my choice for future jobs. Your personnel are great to work with, deliveries as promised, and the pricing is great also. I will get back to you later next week on this particular project.”

“Thank you for following up on the quote. Another supplier was not chosen. From time to time we need play sand. It is not often but there are times when we need it. We also need a reliable source for it as well. After I received the quote and priced it for the job the customer chose to move in a different direction. We like the service we receive from Aggtrans. Our sales rep took the time to notify us that the masonry sand had changed colors slightly. That was a great to me was great customer service. Most companies would just ship, and ad say that's the new sand and its out of our hands. We will continue to use Aggtrans because of the service we receive. The online portal is easy to use as well.”
