"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 contacted Discover to ask for a quote in the morning and they responded with the best price and the shortest window to come over. They only had a one hour window as opposed to some other devices that have 4+ hours which they arrived as promised. Not only did a service tech arrive, but the manager as well. Both were extremely professional and assessed the problem before taking any action. They isolated it to the mainline and was able to run a commercial snake to have everything unclogged in less than an hour. Once everything was tested with the other water lines to make sure the problem was resolved they cleaned up the work area and hooked up the lines back to the washing machine. I can't express how much I would recommend this company for jobs big or small. I'll definitely be reaching out to them for service in the future."

Excavating questions, answered by experts

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.

If you’re planning to dig on your property, you’ll need to check for underground utility lines. Call the national call-before-you-dig 811 number. Once connected to an operator, you can schedule a site visit to mark underground lines. This way, you won’t accidentally dig into pipes and can cause major (read: costly) issues.

While you can save some money by digging your own pool, you may end up paying more in construction equipment rental fees in the long run. You could, however, focus your DIY energies on lowering the cost of leveling your lawn for your pool or filling in surrounding landscaping after construction.

Excavation is priced in cubic yards, so you’ll need to find the volume of the area in order to calculate costs. Multiply the length, width, and proposed depth of your excavation site, then convert it into yards to get the volume. Multiply this figure by the price per cubic yard.

Most homeowners can measure by hand to get a rough estimate, even if it’s tedious. You may want to pull out a tape measure or use a string to help mark the area.

The time it takes to build a pool—and dig out the area—varies based on the pool size and type. A professional excavator will take between four and eight hours to dig a pool. The process will take longer if they encounter large boulders or tree roots. Keep in mind that this is a small part of the process in the long run. You will need between eight and 12 weeks to build a pool from start to finish, including the time to apply for permits.
