"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

If you have a broken sprinkler pipe underground, there will be some signs you can easily spot to locate it and take action. These include leaks, water spouts, flooding, consistently damp areas on your lawn, low water pressure, and grass around the sprinkler head that’s taller and darker than anywhere else in the yard. 

If there are no obvious signs of a broken pipe, you can use tools such as water leak mics, leak noise loggers, audio devices that record leaks, and acoustic testing links. 

Broken pipes can lead to uneven watering, plant damage, and higher utility bills. The longer you wait to fix them the more the repair cost may be.

Trenching and boring are two distinct methods for installing underground utilities. Trenching involves digging a channel using equipment like an excavator, trencher, backhoe, or shovel. While it is a simpler process, it causes significant disruption to the surface, landscaping, and surrounding ecosystems.

Boring, also known as directional boring, is a less invasive alternative that uses a drill to create a tunnel for utility lines without disturbing the surface. This method is more precise and is ideal for installations that need to go underneath buildings, roads, or bodies of water. Although boring is less disruptive, it is generally more expensive than trenching.

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.

You do not have to dig footers for a deck as long as it meets local code and holds up to weather in your area. If you live somewhere that experiences high winds and earthquakes, you may need to dig for your deck posts. Deck blocks, post anchors with base plates, and helical pile systems are the three no-dig deck post options you can choose from if local code permits.

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.
