"I highly recommend Frank Cervantes, from "At Your Service Plumbing." He is more reasonably priced than other plumbers, I have used in the past. Frank performs his work to satisfaction of everything functioning properly. 2/27/26, Frank lowered and secured a pipe from my black water tank, as water and waste were not flowing properly. He unclogged my toilet, that had been backing up. 3/04/26, Frank returned, as Toilet was backed up with water again. Frank checked the pipe with his computer camera, in which there ended up being (3) major blockages, from the pipe up into the black water tank. Frank, used every piece of his equipment to completely clean out the tank and pipe. I was able to view the completion of process on his computer. Frank, is very professional, and personable. I give him an A+ rating."

Excavating questions, answered by experts

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

Yes, chipmunk holes may have two or more entrances. Chipmunks can create an entire network of burrows. Having multiple entrances makes it easier for them when trying to escape from a predator, such as a snake, or if an entrance collapses due to flooding. Each entrance leads to the nesting chamber underground, which is where the chipmunk spends the majority of its time sleeping.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.
