"Konnaugh and his team were a pleasure to work with. They showed up on time, and after demolishing and removing a hot tub and a chicken coop, they left my yard practically spotless! They did such a great job, I would highly recommend them to anyone looking for junk removal or yard cleanup ??"

From start to finish, they were professional, reliable, and paid incredible attention to every detail. The quality of their craftsmanship is outstanding, and they made the entire process smooth and stress-free. Our kitchen turned out even better than we imagined, and we’ve received so many compliments on it. We highly recommend Twin Timber to anyone looking for a beautiful, high-quality renovation. Thank you for making our dream kitchen a reality!"

"I was very pleased with the landscaping work I had done. I wasn?t sure exactly what I wanted or how much it would cost, but Chris worked with me to create a landscaping plan, and it turned out to be exactly what I wanted. When the work was finished, the area looked beautiful, and the price was very reasonable. I was so pleased with the results that I plan to have Chris back in the fall to do some additional landscaping. I would highly recommend Chris to anyone looking for quality landscaping work.

Excavating questions, answered by experts

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.

Skunk digging looks like a series of small, cone-shaped holes on a lawn or around the perimeter of a home, porch, deck, or shed. The holes that skunks dig when searching for grubs tend to be no more than four inches in diameter and may be up to four inches deep.

We recommend removing the stump, and grinding is a popular way to do it. You can also dig out small stumps or stumps that have fully decayed instead of grinding them. However, don’t try using acids or fire for killing a tree stump, which is a fire hazard and illegal in many areas.

Leaving the stump alone invites eventual problems, including attracting termites, mold, and fungi.
