"Provider was prompt, professional and friendly.  Arrived at the agreed upon time for a free estimate and performed work same-day after we agreed to the price.  He stuck to the price despite taking longer than expected and more work than usual due to worn-rusted pipes in my home.  Cleaned-up after himself and left no sign that work was done other than our new, working toilets.  We are very pleased and reccomend McDonagh & Sons Plumbing & Sewer Inc.

Excavating questions, answered by experts

The average cost for pool excavation is $2,500. This cost can range from $450 to $4,500, depending on the pool shape and size, time of year, and any need to move buried utilities. 

When excavating for your pool, you might have to move existing utilities. You can expect to pay an additional $15 to $25 per linear foot to move gas lines. To move a septic system, it’ll cost an additional $2,000 to $20,000. A pool that is 10 feet by 12 feet averages $450 to excavate, and a 20-foot-by-40-foot pool averages $3,020.

Most professional excavation teams will charge between $8 and $15 per cubic yard. Calculate the cost by finding the volume of your pool—width x length x depth—and dividing it by 27. Then, multiply the price by the cubic yards from your equation. Budget for complications like a rocky lawn, hard-to-access pool area, or high local labor prices.

If you’re planning to dig on your property, you’ll need to check for underground utility lines. Call the national call-before-you-dig 811 number. Once connected to an operator, you can schedule a site visit to mark underground lines. This way, you won’t accidentally dig into pipes and can cause major (read: costly) issues.

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.

Maintain open communication and address issues as they arise, ensuring contract terms cover potential delays.
