"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done.

"I needed several trees removed from my property ranging in the height of a telephone pole to smaller trees that were rotting. I got a competitive estimate quickly and was told they could start within a few days, which was a relief due to storms being in the forecast later that week. The crew arrived with heavy equipment as scheduled and they dismantled each tree with precision. The tall tree had branches that hung over power lines, but the crew is made up of true pros and the job was done meticulously and safely. I was very satisfied with the entire experience from beginning to end. "

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.

A cross brace for a fence gate should stretch from the top corner of the gate’s hinge side to the bottom corner of its latch side at a 45-degree angle to the bottom of the gate. This positioning distributes the bulk of the gate’s weight to the base of the post, taking pressure off the top hinge.

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).

Yes, many providers offer design consultations to create unique structures. Confirm with your contractor.

It’s best to opt for a lightweight roof, as a heavy roof adds a lot of weight and pressure to the support posts and hardware and destabilizes the structure. Vinyl is a good, lightweight option, as is a nice open trellis, louvered aluminum or vinyl slats, or fabric panels. Clear polycarbonate is another great option that offers seamless shelter and additional UV protection without completely obscuring the sunshine. You can also choose retractable coverings or an awning that you only use in wet weather or when you need additional shade.
