"Quick response with quote, which was really reasonable. They were able to complete the project right away. I had them remove glued down wood flooring, which is really difficult. A couple hours after they arrived the area was cleaned and ready for install. Will hire again for other projects."

"We hired Rainforest LA to install our front yard landscaping. The design had been done by another company and Yosi worked with the designer and made our yard beautiful. Yosi was professional and responded timely to my texts. The prices were very reasonable and the quality of work was exceptional. We will use this company again."

"Ken is very knowledgeable and professional. My backyard was not draining well in the last rain after a garage extension. He graded the soil and built a paving stone walkway. When I couldn't find anyone to put sods on the soil, he took on the job and did a great job. I am very happy with the work."

"I heard about SES from my friend. He did last year a kitchen remodeling project with them. I wanted to renovate 2 bathrooms, so I called them right away and got 4 more quotes. I felt more comfortable with SES and decided to do the project with them. The result came out greater than I imagined. Thank you guys"

"We had been dreaming of remodeling our backyard for years, and after researching multiple companies, we decided to go with Regal Construction & Remodeling. Best decision ever! Ben and his team were absolutely amazing from start to finish. We wanted a complete overhaul—new pavers, a pergola, custom seating, and landscaping. Ben worked closely with us to create a design that matched our vision while staying within our budget. His knowledge and creative ideas were invaluable. The entire crew was polite, professional, and respectful of our property, making sure to clean up each day. What impressed us the most was how seamless everything felt. The project was completed in a timely manner, and Ben kept everything on schedule with clear communication throughout. We never felt like we were left in the dark, which is so important when taking on a big renovation like this. Now, we finally have a backyard we’re proud to entertain in. The quality of work is top-notch, and we wouldn’t hesitate to recommend Regal Construction & Remodeling to anyone looking for a high-quality backyard transformation!"

Excavating FAQs, answered by experts

Yes, an excavation company is the best option for land grading and yard leveling. General landscapers might be able to tackle these projects, but an excavation company will do a better job because they’re used to operating the necessary heavy machinery. Landscapers might opt to do the work manually, which takes much longer and could cost you more in labor fees. Finally, excavation companies will understand local regulations and know when you need permits to legalize the work, while a landscaper might not.

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 rules and regulations regarding groundwater use vary between states. To find out if you can dig a well on your property, you’ll have to consult these regulations, address any compliance requirements, and get the appropriate permits. It’s also important to check that your intended location has the right geology and water table to support a well.

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.

Yes, professional installations include trenching or borehole drilling required for ground loops.
