"Edgar and his employees were amazing. Their bid was the best. Other guys said they would have to rip up pavement that this crew could do no problem minimally. The guys were so well groomed and polite. Not that that matters but it was an extra bonus. Lovely crew and incredible job in a few days. I will for sure use them again."

"Giovani and Dell of Ultra Construction were great to work with and they responded quickly and efficiently to our contractor inquiry. They came out the next day and provided a fair and reasonable estimate. Dell and his crew, including Julian came out and had the concrete walkway and stairs installed in just one day. It looks great and we couldn’t be happier with the results. Their prep work and cleanup were outstanding. Would highly recommend this company for any concrete construction work"

Excavating questions, answered by experts

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.

A walk-behind trencher can cut through roots as long as they’re not too thick, making a project much easier than digging with a shovel and other hand tools. Assess your terrain and the number of trees in the surrounding area to determine if a walk-behind trencher will ease the job. Digging a trench by hand is much more time-consuming and labor-intensive. 

Because decomposed granite is a durable material, a crushed rock or gravel base is optional as long as the DG is properly installed and compacted. However, installing a base is a good idea because it will ensure proper drainage and stability and act as a weed suppressant (although you may still occasionally have to pull weeds). Installing an adequate base can also increase the durability of driveways and walkways. If you forego the paver base or gravel underneath, line the area with landscaping fabric to avoid weeds.

Excavation and grading are both generally necessary for designing your foundation, and leveling the ground where your foundation will go. These steps can also prepare the area by removing vegetation and anything else that could interfere with your home’s foundation.

The cost to repair a crawl space runs between $1,500 and $15,000, depending on the extent of the damage. Major flooding or water repairs can cost up to $10,000 for removal and repairs. If you simply need to clean your crawl space, expect to pay between $2,000 and $6,000 for a major cleanout. Replacing a crawl space beam due to rot or damage can cost between $1,500 and $5,000, while removing and replacing damaged insulation costs between $1,000 and $4,000.
