"With our rather old cabin-style home, the plumbing from the kitchen sink had a plug of hardened grease over 30 years old. We discovered this the first day when they drilled through it with a snake; we had them return a couple of days later with a hydrojet unit to clean it out. Our house is located in the mountains, and may not be particularly easy to get the equipment out here, but they had very little difficulty. They used a lengthy hose to go around the back of the house, then sent the nozzle through the pipe behind the trap to clear it out. I was originally concerned about navigating past the elbow joints in the pipe, and the fact that we have a septic tank that I didn't want to fill up; but neither was a problem, and the job was done in about an hour. The sound of the drain flowing never sounded so sweet."

"This job probably would have gone much smoother if the contractor had been at the job site regularly. One man was very competent, but the help hired needed lots of supervision. And since the dryrot portion was time and materials, I was very frustrated, workers were late, talked on their cell phones, and were not efficient. The contractor's response when I told him I thought he was going to be on the job site was, "I never said I would." He relied on daily conversations with the main carpenter. This might have worked had better workers been hired. After 4 months, a second competent carpenter was higher for a short time and that went well. I think the stucco sub-contractor did a good job but they were messy. The sheetrock sub-contractor took a long time patching, often missing spots and returning. The tile sub-contractor did not lay the hand-made tile very well so I have a constant reminder on his work. The painter did an pretty good job (the stucco is very rough)."

"We bought a 'fixer-upper' and of all the contractors (and we have worked with A LOT on this house) he is the top. He is prompt, he always follows through, his team works hard and gets the job done fast and well. If there are any concerns he comes out personally and takes care of them immediately. He is flexible and thinks on his feet. His pricing is very reasonable. There wasn't a thing that we didn't like about working with Nato and team. He is our official go to guy for landscaping and other projects. We trust Nato, his work and recommendations to us We would definitely recommend him to our friends. My husband found him on Angie's list and it was one of the best finds we have had in the 3 years we owned the house."

"I would give them six stars if I could. The entire process was smooth and pleasant. Fair negotiation, good price, excellent execution. We had to replace sewer lateral - a major work - and Faren and his guys did everything highly professionally and on time, including taking care of city permits, inspections, and protection of the site. Warmly recommended to everyone."

"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."

Excavating FAQs, answered by experts

The best type of soil to build on is a mixture of sand and clay, known as loam soil. Loam soil has the best combination of these soil types to build a foundation on. The clay particles help with water retention, so it won’t erode like sandy soil might, and the sandy particles help with drainage, so you won’t see unsafe soil expansion or have an increased risk of leaks from water sitting against your foundation.

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

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.

To drill a shallow well, you may be able to use a drive well point. This is a tapered point that is driven into the ground. A drill bit at the end of PVC pipe may be another option to consider. A lot of the cost depends on what tools are available near you.

A trench that is less than 5 feet deep often doesn't require a protective system. Most residential trenches will not go this deep (the typical residential drainage trench is just 18 inches deep). In the event that an excavator needs to dig more than 5 feet beneath the surface, a protective system is required unless the excavation is in entirely stable rock.
