"This was a complex project with a lot of moving parts.
Several thousand square feet of patio, complicated pool coping and a significant amount of reconstruction. The land I gave Carl to work with was ugly and unstable.
I give Carl an A for time and price because of the value he brings to the table. Not because he's the cheapest or the fastest sprinter.
Some significant challenges materialized over the course of the job that added time and cost to the project. The great thing is Carl rolled with the punches, reacted fast, didn't compromise quality, and never asked for more money.
This was not an easy piece of land to work with. A 40 year old pool patio on shaky foundations.
His foreman/mason Eddie is the only person I trust to do anymore work on my hardscape/landscape. His ability, attention to detail and work ethic is unquestionable.
Carl brings 30 years of experience to the table; great design ideas, flexibility, problem solving, vision..........value!!
Additionally, Carl has a fantastic network of partners that are just as reliable.
I would be happy to provide a reference to all serious buyers.

Excavating questions, answered by experts

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

Water lines are buried at various depths, depending on the type of line. For example, most sprinkler lines are buried between four and 12 inches underground. On the other hand, water mains usually sit between one and 3 feet below ground. However, they can go even deeper in cold climates to prevent freezing.

Landscape edging is more DIYable than trenching. You can DIY your own digging projects, but proceed carefully and only with proper knowledge of the equipment and appropriate safety measures in place. Keep in mind the project's scope and estimate how long it will take you to do it on your own. While you can certainly save money by DIYing home improvement projects, you can’t exactly hide an unfinished—or worse, ruined— landscaping job from the neighbors. It’s always safer to call an excavation pro near you to get an estimate.

Yes, you can install a trench drain if you already have concrete in your yard or garden. While it can complicate some aspects of the job and slightly run up the cost, it is doable. Residential trench drains can be easily retrofitted to outdoor areas with concrete without having to remove excessive amounts of your patio, pool area, or decorative walkways.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.
