"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"

"Finding a plumber who is there to solve the issue and not try to redo your whole bathroom is hard to find. Everyone wants to cut and replace but New Era Plumbing took the time to diagnose and fix what was needed. Efficient. Cost effective. Has the skills, knowledge, and confidence to do it in one morning. I feel like lots of plumbers wanted to hedge on what they could deliver, especially since they are turning off your water. I’m very grateful to finally find a skilled professional."

"He was available by phone, and was flexible in scheduling meetings which is great. He was professional, and seemed quite knowledgable. In the end, I didn't use Nato's services because his quote was twice as much as the other contractor I was considering. Perhaps his prices may be more competitive in other services he offers. Either way, working with this company was a pleasant experience."

"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."

Excavating questions, 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.

Yes, trenchers can go through gravel. Gravel is made up of smaller, softer rocks that certain trenchers are able to cut through. Just be sure to use a rock wheel trencher or chain trencher, both of which are made to cut through rocky landscapes and gravel pathways without dulling the teeth or chain.

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.

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

A walk-behind trencher can cut through roots as long as they’re not too thick, making a project much easier than digging with a shovel and other hand tools. Assess your terrain and the number of trees in the surrounding area to determine if a walk-behind trencher will ease the job. Digging a trench by hand is much more time-consuming and labor-intensive.
