"Actually, I had a demolition done of the concrete on our patio. (and demo, too, of a huge tree stump and root in the middle, which had pulled up sections of concrete). The person who was contracted to do the work was very pleasant as well as thorough as he drove a machine that pulled up the concrete. He was able to finish in the "nick of time" (before colder more unpleasant winter weather set in). The overall estimate for a new patio itself seemed quite high (esp with a stone staircase). So- I opted just to go with this co. for the demolition part, and I was pleased. They also leveled the ground and installed a new gutter pipe which went underground to the edge of what would be a new patio area. Thank you very much!"

Customers say: Quality work

"It went extremely well. They knew what they were doing. When something went wrong they took care of it. They were punctual. They showed up when they said they would. They were clean and didn't leave any trash. We were extremely pleased with them. The retaining wall 8 feet high and 90 ft long. I would highly recommend them."

"Prior to these guys saving our property, we foolishly hired an under-qualified contractor to install a large patio and retaining wall system. It turned out to be a never ending nightmare from the start that left us with pooling water everywhere, mud leaking thru walls and stairs that were falling apart. We hired Classical Pavers to hopefully resolve all our issues, and boy did they deliver. These guys are true landscape engineers! They uprooted the previously installed pavers, flawlessly re-pitched and graded the base, planned for all the possible drainige issues that might come up, and completely cleaned the pavers and property of any remnants of their work. I could not be happier with the professionalism of every level of their services. I would absolutely recommend them, and only use them for any and all future projects."

Landscaping FAQs, answered by experts

A scattering of leaves won’t pose a problem through the winter, but a thicker layer of leaves may not decompose before the first frost and can instead weigh down your grass and harbor mold or fungi. A thick layer of leaves also cuts off light and air that grass needs to grow. That’s why we suggest removing thick leaf layers within several days if possible. If your lawn goes dormant over the winter and snow has already caught up with you, then remove the leaves in early spring before your grass-growing season starts so your lawn can thrive.

Late August, September, and mid-October are the ideal months for planting a young tree. However, the best time to plant a tree ultimately depends on when the weather transitions to fall-like conditions and eventually winter frost. As long as the hottest days of summer have passed and the ground hasn’t frozen yet, you can still successfully plant trees.

The best time to plant is between spring and autumn. Springtime weather is typically mild and is when nurseries start to bloom. When the summer weather arrives and it’s hot out, it’s best to avoid planting bare-root plants, but you can still plant many in-container varieties. The first sign of fall is another great opportunity to plant biennials if you live in southern states, or a lovely vegetable garden up north.

Most bamboo can send roots down two to three feet into the ground. However, when stopping bamboo from spreading, the focus is on the runner roots or rhizomes. These roots are much shallower, staying 12 inches or less from the surface, so they’re easier to find and remove. But if you want to remove the bamboo entirely, you’ll have to dig out the full root system.

Determining how many boulders you’ll need for your landscaping project depends on the area you need to cover and how big each boulder is. First, you’ll need to determine how big of an area you want covered, then divide that by the base surface area of the boulders. A landscape professional can help you determine how many boulders will be right for your project.
