The crew and Ivan arrived on time, got straight to work, completed the job safely and timely! Cleaned up EVERYTHING ! They put the trunks where we asked and dumped the mulch where we could easily spread it! We will have them back to do some pruning in the fall! Thank you"

"I interviewed a few people before making my decision using Rok and Iâ m glad I did. I did a complete gut renovation and he basically made my revision come to fruition. Even with the delayed/problems with renovations he always kept me informed. U told me he would always have someone at my house working and that he did. Not like the contractors Iâ ve worked with in the past that say that but then once they get the job.. the â oh someone would be thereâ and no one comes. I had a leak issue and he made it to my house 10 pm to assure it was taken of. Roc is reliable and hard working."

Arborists questions, answered by experts

On average, a prefabricated pergola kit takes one to four hours to build. Prefabricated pergolas are the fastest to install and could save you money, while custom pergolas can take several days to install, ranging from eight to 16 hours. The number of workers on the project can also impact how long it takes to install a pergola. 

If you need to build a concrete slab, level your property, or remove obstacles from your yard before building a pergola, then your project could take several weeks to complete.

DIY is possible for basic designs. Professional installation ensures stability and compliance with building codes.

Though this is a project that can be DIY-ed—there are kits available for $600 to $7,500—hiring a pergola pro will ensure the final product is structurally sound. A savvy homeowner may already have all the necessary tools and know-how to build a DIY pergola, but the difference in cost isn’t that much, and having help will make the process easier in general.

A pergola needs to be anchored, and typically, concrete is the best anchor option. Pergolas should be anchored to a concrete slab or concrete footings, and this is commonly required by municipal building codes. When applying for a permit to install a pergola, be sure to check the anchoring requirements as well.

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