Ordered 11 ton of 2B limestone or half a tri-axel for $550. delivered same day and the driver was a nice guy which was great. However I had called a couple other vendors who didn't get back to me for a couple days only to find out I could have purchased a whole tri-axel load, 22 tons for around $500! That's my mistake for not waiting on their quotes. but shame on Pennsy for being double the price! Leason learned.

Unethical company. These people were out driving around behind my house in cement trucks all night long. Completely WRONG to do this right by residential homes. Hire a company with integrity.

Great place to order concrete, stone or asphalt. As long as you know what you are doing with it when it arrives. I've used them on several occasions and never had a bad product. They also sell bulk ice melt, decorative stone, block and many other construction supplies. They've been here since the nineteen thirties that should say enough. For a company to be around that long, they sure are doing things right.
