"Our 38 year old home had water line leakage problems that were not only reflected on our water bill but with a "pooling" puddle near the house. Another plumber came out to make a repair visit and a follow-up "problem" visit a month later that still did not stop the problem. A month later when the problem arose for a third time we went on "Angi' seeking a replacement of the line. Robert of Coles Excavating contacted me along with a number of others. His personal conversations, both helpful and informative, impressed me; also his comparatively lower bid. Coles Excavating not only did a fine job replacing the water line, (I waited 30+ days before sending in this review) but Robert's continuing information and support as things progressed was greatly appreciated. My experience with Cole's, in a stressful situation, was truly an excellent one."

"PDW SEPTIC IS A VERY DIVERSE COMPANY. Not only do they pump septic tanks but can evaluate your current system, do major modifications, complete installation of new septic systems along with the leaching system. Tony, the foreman has over 35 years experience in the septic field and is very experienced in all phases of taking care of all your septic needs, as he did mine. Tony explained to me how your septic system is the very heart of your home as it can’t function without it. Thanks PDW, you gave my 50 year old septic system a new lease on life, and that I am grateful for"

"VERY EXPENSIVE; VERY GOOD; you get what you pay for Had water leak in ABS piping connection in bathroom. Fixed it very nicely. I was a somewhat upset that their quote over phone was round $400 but final charge was $816.08; I had emailed them extensive description and multiple photos so they could provide more accurate estimate since they do not do free estimates though I realize they found some other issues they had to fix that were not apparent in my description and photos. I was also upset that the impression they gave me was only one plumber would do the job but he showed up with a trainee and charged me for trainee time also. I will use them again only for involved or complex jobs. They are too expensive for simple plumbing jobs such as toilet install or faucet install."

Excavating FAQs, answered by experts

Downspouts should be buried at least 5 to 10 feet away from your foundation. This can vary depending on your local building codes, soil type, and property slope. The main goal is to ensure water is directed away from your foundation.

Drilled wells have a pipe sticking up that’s covered in a plastic or metal casing. On the other hand, a dug well will look like a big hole in the ground and is more similar to what you’d see in a fantasy or Western movie. If you want to be sure, contact the city for documentation on your property’s construction and excavation history. 

The best method for digging a trench depends on the scope of the project. For a short, shallow trench (less than 2 feet deep) in light, soft soil, digging by hand may be sufficient. However, digging by hand is labor-intensive, so consider the effort required. A machine trencher is the better option for longer trenches (over 100 feet), deeper ones, or when dealing with difficult soil conditions, such as rocky or hard ground, or obstructions like tree roots. A machine can save significant time and energy in these situations.

No, a ditch isn’t a trench. A ditch is an open, relatively shallow channel that’s carved out of the ground and used for drainage purposes. In contrast, a trench is a deeper excavation that’s entirely underground. Trenches have many uses, including gas lines, sewage systems, and electrical wiring. Unlike trenches, ditches don’t get filled back in with dirt after they’re dug.

There are several different factors that influence how long it takes to excavate. For a foundation, it could take anywhere from three days to three weeks. It can take even longer if you face weather-related delays or an inaccessible site that’s riddled with boulders and rough terrain. It may also take longer if you have clay soil, which is more difficult to dig.
