"Over the past year or so, I’ve worked with several different contractors. Some I wouldn’t hire again for various reasons — but a few delivered excellent results. When I find people who are reliable, reasonably priced, and take pride in their work, I like to share that information so others can benefit as well. More than once, friends have hired these same contractors after reading my reviews and were just as satisfied. So, in the spirit of helping neighbors find trustworthy professionals, I can personally vouch for: They completed work for me today, (January 12, 2026) and I couldn’t be more impressed. They arrived on time, worked safely and efficiently, cleaned up the yard beautifully, and the price was very reasonable. Watching their crew work was mesmerizing — true professionals. If you need tree work now or in the future, you must consider this contractor. Their work is fantastic. I also posted this review on my Facebook page. Terry LaManna, Dover Plains, NY"

"Galvez Tree Service was the best decision we made for cutting down the dangerous dead trees on our property! They were professional, reliable and reasonable!

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"

Arborists questions, answered by experts

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.

For optimal sun exposure, strategically place your trellises along the northern boundary of your garden bed or adjacent to a fence or wall. Conversely, consider situating the trellises on the southern side in sun-drenched locales to create soothing shade for heat-sensitive plants, effectively screening and sheltering them from the scorching summer sun.

Building a pergola yourself costs less than hiring someone to do it for two reasons. First, a contractor will charge a markup on the materials. Second, you’ll save the entire cost of labor. In exchange for the money you save, you’ll need to dedicate at least one full weekend to the project.

Although dependent on the type and size of lumber, most 2-by-4-by-8-foot pieces of lumber cost anywhere from $3 to $6. Softwood lumber like pine falls on the lower end of the spectrum, while hardwood lumber like oak or walnut falls on the higher end. Different retailers and lumber yards can also vary in price, so it helps to shop around to compare prices.

Other projects that you can do at the same time as your trellis include painting the deck , installing a pergola, or adding mulch to your garden beds.
