"Thanks to Artistic Landscapes we finally have the yard we've always wanted! It was a project with a wide variety of requests and challenges including a 16-zone irrigation system, patio, fountain, new sod lawn, synthetic turf, 2 different types of fencing, multiple paths with different materials, lighting, rock garden, patio planter, raised garden beds, and more. Robert's fantastic crew, led primarily by Sergio, showed off their expertise and handled everything we threw at them, including projects like a crevice garden, that they'd never done before. Their website is a treasure trove of inspiring ideas! Kurt & Carol Putnam"

"Excellent service. The pruning of the 2nd oak tree and the Hawthorne tree was done one day, and all other work done the next day. The 4-person crew was very professional, kind, and respectful of the property. The large oak I had removed was right up against a new fence, and not far from the side of my house. And, it was not in an area to get a bucket truck nearby. They arrived right on time at the start of the day and worked hard with minimal breaks - very impressive. They ground the stump from the large oak as well as grinding a couple of leftover stumps from previously removed holly trees. Their cleanup was superb! They even blew stuff off the top of my roof! And the wood cut down was nicely rolled together - not just dumped into a large messy clump! And, they were cheaper than another bid I got from a company here on Angie. I cannot recommend them high enough."

Arborists questions, answered by experts

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand. 

If you have a knack for DIYing, a trellis can be built from scratch from all kinds of materials. However, if time is of the essence, it’s far easier to buy a trellis ready-made and put it together at home.

Consider the height of the plants you plan on using with the trellis, as they will need the right amount of support to grow.

Wooden pergolas can last five and 12 years as long as you maintain your pergola. Make sure to clean, stain, and seal wood pergolas every two to three years to protect the wood from insect damage, rot, and decay. 

Vinyl or aluminum pergolas can last a lifetime. The only problems you may encounter with these pergola materials are weather-related—heavy rain storms or snowfalls. Check the stability of your pergola every season. You may need to add new supports or replace broken beams on an as-needed basis.

Rather than using a common two-by-four piece of wood for a rafter, you probably will use two-by-six, two-by-eight, two-by-ten, or even two-by-twelve boards. Wider lumber is typically a better choice in a larger building as it provides more sturdiness. Some installers may use wider lumber for rafters near the edges of the roof, where the greatest stress occurs, and save money with narrower lumber toward the middle.
