"I am an Electrical Engineer by education and trade, working for several high-tech firms in Silicon Valley over a 45-year career, so I've never felt the need to call an electrician. But I know my limits and repairing an electrical open circuit routed in underground conduit is one of them. After trouble shooting the issue, I knew there was a break in the line so I called Mike at M3 electrical. He put me on his schedule, showed up on that date (even a little early) and in less than two hours had the issue fixed. Not only that, but he advised the type of 2-wire Romex that had failed was not the proper wire for an underground application. He pulled about 75 feet of the proper wire through the conduit and even installed a junction box at my street light for a clean installation. Costly you think? Not in my opinion! If I ever need electrical work done in the future, Mike is the guy I will call. I suggest you do as well. Mark S. A very happy customer"

"I contacted M&J Prime Builders on a Sunday morning via an urgent request on Angi (Angie's List) to repair a leak in our backyard irrigation system. Javier contacted us immediately and arrived at our home in Concord with his business partner, Marcos, within 90 minutes. They were very attentive, professional, and accommodating, especially for our unexpected Sunday morning emergency. They not only repaired the leak but also addressed another issue that had arisen with our shutoff valve. Their estimate was very reasonable and accurate, and their work is top-notch.

FAQs for retaining wall installation projects in Knightsen, CA

Landscapers typically charge $25 to $50 per person per hour, which equals around $50 to $100 per hour for a two-person crew. These rates can vary depending on your location, the size of staff needed for the job, and overall job type. For example, a larger crew will be needed for structural additions and hardscaping versus planting flowers. 

When it comes to landscapers, licensing laws vary. Landscaping architects are required to be licensed in all 50 states, whereas traditional landscaping contractors are not typically required to hold a certification. You’ll likely be working with a landscaping contractor for most residential projects. If you are redesigning your whole yard or adding in hardscape features, you will work with a landscaping architect at some point during the project. Be sure to check our state licensing tool to review the local landscaper guidelines.

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

A paver patio can last anywhere from 20 to 100 years, depending on the type of pavers and how well you maintain them. 

Travertine pavers are usually the most durable, lasting 100 years or more, with regular maintenance. Concrete brick pavers have a variety of shapes and colors available and typically last 25 to 50 years. Traditional brick pavers have a more classic look, lasting around 20 years with proper maintenance.

Landscaping costs around $3,500 but varies widely from $200 to $14,000. Factors that play a part in your final landscaping price tag include:

  • Location

  • Yard size

  • Project size

  • Materials

  • Land preparation

  • Type of landscaping

Considering so many factors, it’s not surprising that the overall costs can differ. A typical landscaping project is flower bed installation, which averages between $800 and $3,000. However, landscape lighting installation is a higher-end project, with a price tag of $2,000 to $6,000

The cost of a paver patio is $3,800 for a 280-square-foot patio on average. Depending on the patio size, paver material, and design complexity, this cost can range from $2,400 to $7,000 or more.

The size of your patio is a significant factor in the project’s overall cost. If you're building a smaller patio of only 60 square feet, your costs will be closer to $480 to $1,500. If you want a more luxurious 900-square-foot patio, you'll spend closer to $7,200 to $22,500.
