"From start to finish super easy to work with. They worked around my schedule and kept me under budget. The crew from A.T.F Construction arrived on time they were knowledgeable and professional. They kept me well informed through the entire process. I can’t thank them enough for saving me money where I didn’t need to spend it. They were honest about products and which ones they recommended. I’m over the top happy with the turn out of the floors and paint. A.T.F construction made my home look like new again. Definitely without hesitation going to use them in the future."

"Mountain top Enterprises got back to me very timely. They were on time, go getters that got the job done. There were some alterations ,upgrades that needed done and they troubleshooted it perfect. They fixed the well leak, added a pressure valve and even helped get my sprinkler system on. Hats off to them. It was a little more expensive than the quote but well worth it."

Excavating questions, answered by experts

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.

Downspouts should be buried at least 5 to 10 feet away from your foundation. This can vary depending on your local building codes, soil type, and property slope. The main goal is to ensure water is directed away from your foundation.

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.

If you have a broken sprinkler pipe underground, there will be some signs you can easily spot to locate it and take action. These include leaks, water spouts, flooding, consistently damp areas on your lawn, low water pressure, and grass around the sprinkler head that’s taller and darker than anywhere else in the yard. 

If there are no obvious signs of a broken pipe, you can use tools such as water leak mics, leak noise loggers, audio devices that record leaks, and acoustic testing links. 

Broken pipes can lead to uneven watering, plant damage, and higher utility bills. The longer you wait to fix them the more the repair cost may be.

The rules for trenching and excavation include setting up and following safety protocols, learning how to use tools and machines properly, and ensuring there is a safe exit for all workers. Keep heavy equipment and materials away from the edge of the hole or trench. Call the 811 dig line before starting any excavation or trenching project to ensure you don’t hit any electrical or gas lines.
