"Quick response with quote, which was really reasonable. They were able to complete the project right away. I had them remove glued down wood flooring, which is really difficult. A couple hours after they arrived the area was cleaned and ready for install. Will hire again for other projects."

"I recently hired Pro Bright Construction to remodel my bathroom, and I couldn’t be more impressed with their work. The team was punctual, respectful, and highly skilled. They took the time to listen to my ideas and offered expert suggestions to enhance the design. The project was completed on time and within budget, which was a huge relief. They kept the work area tidy and made sure to minimize disruption to the rest of the house. I’m beyond thrilled with the final result. If you’re considering a remodel, I highly recommend Pro Bright Construction."

"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again."

FAQs for excavation projects in Diamond Bar, CA

Unfortunately, some plumbing scenarios, like a broken sewer pipe repair, will require excavation to complete the job. Plumbing excavation costs range from $30 to $70 per cubic foot. However, if you need additional trenching, expect to pay an extra $4 to $12 per linear foot. Keep in mind that these costs are on top of the plumbing repair costs, and they don’t account for labor costs. Consult your excavation specialist to determine an accurate estimate for your job.

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.

The cost for residential excavation is $3,200 on average, ranging between $50 and $200 per cubic yard. Total costs could range from $500 to $15,000, depending on the project type, yard size, and soil type. 

When a project needs an excavator, the contractor will subcontract one as part of the larger project. If you hire an excavation specialist, you can expect to pay between $40 and $180 per hour. When excavating, if you have soil with excessive rocks or clay deposits, expect an additional cost of $200 to $1,200.

Warm weather seasons like spring and summer are ideal times to excavate due to the ground being softer and easier to dig through. However, it is important to note that bad weather, like heavy blizzard conditions or torrential rainfall, can prolong the project length, increasing costs. That’s why it’s best to avoid excavating during winter or hurricane season, depending on your home’s location.

While completing an excavation project yourself is possible, we don’t recommend it. You’ll likely need to buy or rent the equipment necessary for the job. This equipment costs as $100 per hour or $2,200 weekly, increasing by as much as 50% for larger jobs. 

In addition, completing an excavating job yourself poses a safety risk. If proper marking hasn't occurred, you risk hitting buried cables and other critical piping, like gas and water lines. Additionally, if working with excavation equipment, you’ll need to steer clear of any overhead wires. Leaving this project to an excavating professional is best.
