"We recently had the pleasure of working with In Season Landscape & Hardscape, Inc., and I want to take a moment to highlight the exceptional work of Hugo. From start to finish, Hugo’s craftsmanship, professionalism, and attention to detail were nothing short of outstanding. What truly set Hugo apart was his determination to not only meet but exceed expectations. He was committed to keeping the project on schedule and followed through on every detail to ensure the job was completed on time—something that’s all too rare in construction. When an unexpected material shortage threatened to delay progress, Hugo took it upon himself to drive to San Diego at 4 AM to pick up the needed supplies. That level of dedication speaks volumes about his work ethic and pride in his craft. Thanks to Hugo and the team, the final result was flawless. We couldn’t be happier with the transformation and the experience. If you’re looking for a professional who genuinely cares - ask for Hugo!"

Arborists questions, answered by experts

Pergolas and similar overhead outdoor structures will typically be subject to building code regulations. Every municipality is different, and some may have specs or permit requirements, so it’s important to double-check. Some HOAs may also have restrictions on what you can build, so be sure to check with your HOA as well (if applicable).

Installation typically takes 2-5 days, depending on the structure size and site preparation.

Yes, many kinds of building permits exist for various projects in and outside your home. Each city sets the permit categories, but they typically cover new construction, alterations, and demolition. For example, you will need a different permit to finish a basement than you would tear down the patio.

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.

Both cedar and redwood are some of the best woods for pergolas. Both are rot- and insect-resistant and have gorgeous natural tones that age well. Redwood tends to have a longer life span than cedar, but it also comes at a higher cost. While both options are durable, the best wood between these two for your pergola will primarily depend on your budget.
