"Daniel was awesome to work with. He came out and provided a solid estimate in a timely fashion. We had an unexpected sprinkler line that was in the middle of our excavation area and he took care of that. He also provided the materials for a retaining wall that we hadn't initially planned for, and he added that to the project scope without issue. I will definitely reach out to Daniel if we have another project like this one."

"Owner of the company came to my property and he gave me a thorough bid covering the cleanup and disposal of 30 yrs of debris. He had his own dumpster trailers and his own equipment necessary to do the job. I am a very environmentally conscious person and he took the time to separate recyclables and lawn debris in different dumpsters for removal. He also gave me a fair bid to do the differed maintenance on my out buildings around my property and was able to restore multiple buildings that other contractors said would have to be torn down-removed and built new at a larger expense. We’ve recently had him back to build a hot tub surround with transparent roofing out of 120 yrs old barn wood posts that was saved from a building that couldn’t be remodeled. Definitely will have him back for future projects, highly recommended."

FAQs for excavation major grading or resloping projects in Portland, OR

You can excavate in winter, but frozen soil slows down the process and increases labor costs. Many grading companies offer discounted rates during their off-season, so ask for a winter quote and weigh the savings against a longer timeline. A brief conversation with a local professional will help determine whether cold-weather excavation is suitable for your site.

Foundation digs can be completed in as little as three days or take up to three weeks. Soil density, access, weather, and hidden obstacles all play a role, so every timeline is a bit different. Have your contractor walk the site and flag any potential issues early—clear expectations help keep both the schedule and budget on track.

You must always call 811 before excavating. Dial 811 a few days in advance so that utility crews can mark underground lines and ensure the area is safe for digging. Hitting a buried cable or gas pipe can be both dangerous and expensive, and many municipalities will not issue permits unless the site is flagged correctly.

To remove soil during an excavation project, your crew will load the spoil into dump trucks with a backhoe or excavator, haul it to a disposal site, and return for the next load. Efficient hauling keeps the work zone clear and the project moving. Depending on the site and volume of osil, multiple trucks may rotate to maintain a steady flow.
