FAQs for retaining wall installation projects in Diamond Bar, 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.
