"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

The digging depth will depend on the size of the trencher you use. Even smaller units can dig up to 4 feet deep, which is plenty for a DIY job. However, much larger trenchers can reach a depth of 18 feet and are better used by a team of pro contractors, not a single DIYer. As with all home improvement projects, use the right tool for the job and proceed with caution.

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

To locate an underground downspout, you should start by identifying where the above ground gutter drains. Look for an entry point, such as a pipe or elbow leading into the ground. Follow the surface path for signs like depressions, landscaping disruptions, or wet areas after rain. You can use a metal detector or plumber’s snake to trace the pipe underground. For deeper pipes, a professional locator tool or camera inspection may be necessary. Visual markers or utility maps can also guide the search.

There are several methods to hollow out a tree stump, and the best one depends on your tools, experience, and priorities. Common methods include using a chisel and hammer, a chainsaw, or burning.

  • Chisel and Hammer: This is often considered the easiest approach for those with limited tools or experience, though it is the most time-consuming.

  • Chainsaw: Using a chainsaw is the fastest method, but it comes with significant safety risks, especially for inexperienced users.

  • Burning: This can be an effective method, but it is not recommended unless you can first drill holes into the stump. Without holes, the stump will be difficult to light and may not burn completely through.

A power drill with at least a ⅜-inch diameter bit can make the job quicker and easier, regardless of the primary method. While you can use a chisel or chainsaw without a drill, it will require more time and effort. Always wear protective goggles and thick gloves, as splinters are an inevitable risk.

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.
