"Ike gave me a fair price for excavating tough rock and sandstone. Nick did and excellent job throughout the process, was extremely helpful and informative. The 2 are not done and still going to truck in 100 yards or so of fill dirt and possibly some topsoil offering to also grade it after dumped! Works with you if any complications arise. Would hire again."

"Giovani and Dell of Ultra Construction were great to work with and they responded quickly and efficiently to our contractor inquiry. They came out the next day and provided a fair and reasonable estimate. Dell and his crew, including Julian came out and had the concrete walkway and stairs installed in just one day. It looks great and we couldn’t be happier with the results. Their prep work and cleanup were outstanding. Would highly recommend this company for any concrete construction work"

"When we purchased the house, it was a 30 year old home. Almost everybody in the period of five years to seven years wanted to convert to copper plumbing. So what they offered at that time was anyone you referred to if they chose to use their service, you have $500 cash payment which was really nice because half of our neighbors and our family members used them. I do not know what they do now, but it is a really nice service because they are a very good company. They did a great job."

"Miguel completely re-configured our plumbing under the house a few years ago and we have never had issues again. He diagnosed the issue accurately and was able to complete the job quickly and at the highest level of quality. His knowledge of virtually all mechanical and structural aspects of renovation/repair are second to none. I would recommend him without hesitation to anyone and with highest confidence."

"Alfredo contacted me very quickly and I explained our issue. He agreed to come by the same day. He assessed the problem and gave me a detailed explanation of the issue and how to fix it. This included advising me that the repair could be problematic since the pipe was galvanized steel. I appreciated his approach to keep the repair simple and to address any issues as they came up. His estimate was very reasonable and the repair was successful. There was a small leak that started on a separate section which Alfredo came back and fixed as part of the original bid price. He was efficient and responded to all of my questions. That was very much appreciated!"

Excavating questions, answered by experts

To locate an underground downspout, you should start by identifying where the above ground gutter drains. Look for an entry point, such as a pipe or elbow leading into the ground. Follow the surface path for signs like depressions, landscaping disruptions, or wet areas after rain. You can use a metal detector or plumber’s snake to trace the pipe underground. For deeper pipes, a professional locator tool or camera inspection may be necessary. Visual markers or utility maps can also guide the search.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

Hard soil could be a sign of overly dry dirt, either from poor drainage or drought. It's important to test the nutrient levels, density, and drainage capacity of your soil to see if it's absorbing water properly. Begin by adding a light layer of water and observing how long the soil retains moisture. If you experience a good deal of runoff, you may need to aerate your lawn, apply a wetting agent, or hire a professional for a closer look.

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.

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.
