"We hired Concrete by Design to install a backyard patio and sidewalk, and the initial work looked good? we were pretty happy with how everything turned out at first. George Anguiano was friendly and communicative during the project, and even promised to come back for a follow-up walkthrough and to seal the concrete or suggest how it should be done if we wanted to do it ourselves to save money, which we appreciated. Unfortunately, after the job was done, he never followed through. Despite multiple calls, texts, and emails over the course of several weeks (even months), we never heard back. The lack of communication and follow-up is really disappointing, especially since we were told those final steps would be part of the service. I would recommend George work if he actually followed up and stood by his word. Ignoring customers after a job is unprofessional and leaves a bad impression, even when the initial work is solid. We just wish he had followed up. "

"I?m incredibly disappointed with the work that was done at my property. Mine was a clear case of underbidding and miscommunications. The good: nice people and they did do a lot of work. Just not everything they bid on. Bad: the front yard of my house looks worse. We knew we were being fit in but they seemed to be in a hurry. They focused on one aspect. Overcharged a known addition to compensate for under bidding and still didn?t do the clear away that they were supposed to do. If his tractor couldn?t do the work he just didn?t do it. They were supposed to clear back an entire field and he stopped half way and said he was done and then he left the downed brush despite an email I had stating they would remove or burn the brush as their costs. When we pointed out the miscommunication it ?was what it was?. We spoke many times about what we wanted done - it shouldn?t have been a suprise. Again they did a lot of work but I?m upset they didn?t fulfill the terms. Would not recommend. "

FAQs for excavation projects in Lake Oswego, OR
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.
