"I really appreciated the great excavation and fill work that Roland Gagnon did for me. This was a driveway drainage project that required low spot filling and proper grading of the area. The driveway now has the proper slope and is draining properly. Roland went above and beyond my expectations, he will be my first call for any future work."

He also did a great job repairing the warped shelving under my sink. Frank did not loaf around. He continuously worked. I would certainly hire Frank again for any future repairs. I would recommend Frank for any of your projects."

"I posted on Angi and Matt responded immediately and was friendly and professional. He made an access entry from the original basement wall into my addition. There was little to no cleanup for me after! Job well done to Matt and Dickie. I highly recommend Smithtown Landworks."

"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.

"We hired Christian to remove tree stumps on our property. He gave us a price the next day and started work within a week. His work ethic is incredible—he left the site spotless and communicated clearly every step of the way. Since then, he’s regraded our driveway, removed an old chicken coop, and cleared brush. It’s safe to say Christian is our go-to contractor now."

Excavating questions, answered by experts

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.

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

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.

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.

The rules and regulations regarding groundwater use vary between states. To find out if you can dig a well on your property, you’ll have to consult these regulations, address any compliance requirements, and get the appropriate permits. It’s also important to check that your intended location has the right geology and water table to support a well.
