"Tried to schedule a routine maintenance appointment available to customers who signed up for service plans, but Len could not follow through with their commitment three failed/rescheduled appointments in a row!! Each required four hour commitments from the customer. I tried to communicate with dispatch and customer service but unfortunately I don’t think these two departments have an open line of communication between them. I would not recommend for anyone to work with or engage with this company. Len did not follow through on their half of the commitment and disrespected my time as an in office working professional."

I was disabled in 2016 from a medical procedure. Through extensive physical therapy its 2019 I am back and strong as ever. Averaged 25 homes per year.

"David was amazing. I had downspouts and sump pump discharge drainage installed by him in my yard. He ran a drain pipe through my backyard to the end of the property. He also graded to slope all the low points in my yard. I no longer worry when it rains. No more soggy grass and sitting water thanks to him. He arrived early and completed the job within a day. I really appreciate the craftsmanship and the respect for my home. He left the yard better than he found it and cleaned up behind his work. I would 100% use his services again."

Excavating questions, answered by experts

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.

Completion time ranges from days to weeks, contingent on project size, environmental conditions, and regulatory approvals.

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

It can take several weeks for the ground to settle after removing a tree, and the soil under larger, more mature trees can take months. The deeper the tree has been ground under the soil, the longer it will take to settle. However, this extra depth can help you plant new landscaping sooner because you’ll have more space for fresh soil.

A joint utility trench, or joint trench, is a long, buried ditch on a property that contains two or more utility lines rather than running the lines in multiple trenches. Some utilities, like gas and electric or electric and communication lines, are better suited to joint trenching, while others, like water and sewer, are not allowed to be in the same trench.
