"We were very pleased with the job performed. Helio's team expanded and renovated our small master bathroom. We took out a large closet and converted it into our shower. Once started, they worked quickly and efficiently. We did have a few small hiccups, namely using our garage to cut tiles and mix thinset, which created an exorbitant amount of dust coating my tools, bikes, and anything else that was stored in the garage. We also had an issue with the cleanliness of the home after some of the workers left, however, after we brought it to Helio's attention, he made sure to tell the team to do a better job moving forward. Contract was a little confusing, so I would encourage many questions to clarify things ahead of time such as timeline for selecting certain items, confirming when the next payments are due etc. All in all, we're pleased with the project and how it turned out."

Treehouse Builders questions, answered by experts

Trees provide many benefits, including shade, habitat for local wildlife, and cleaner air, so it’s always a good idea to try an alternative strategy like crown reduction before you chop one down. But sometimes, cutting down a tree is the only option (like if it’s severely diseased). A licensed arborist can assess the tree and recommend the best course of action.

The cost of trees varies massively based on the size of the tree and the species. A small Colorado spruce can cost as little as $30, but a golden rain tree of the same size can cost $90. Large trees can cost $1,500 or more, depending on their species and height.

If you want to take your tree-planting hobby beyond your outdoor space, here are a few great ways to do it:

  • Encourage your neighbors to participate in the Arbor Day Foundation’s Tree City USA program, which has a four-step framework that helps communities grow and maintain their own tree cover.

  • Support businesses that plant trees. 

  • Lobby your local government to plant more trees around your community.

  • Donate to a tree-planting charity.

Tree trimming can count as landscaping, depending on how a landscaping business describes its services. Professional tree trimmers are more specialized than landscapers and offer trimming services separately from general landscaping.

When general landscaping companies offer tree trimming, look up the details. They usually mean shaping or seasonal trimming of ornamental trees, which is different from trimming larger trees for health or safety reasons. When possible, look for a licensed expert that specializes in trees and tree health.

If you’re buying a small tree with lots of room to grow, expect to pay around $100 to $200 for a potted version. But if you’re buying a larger tree—say one over 10 feet—prices rise, starting in the $500 to $600 range and increasing quickly from there. Keep in mind that paying for professional palm tree planting or transplanting services will increase the cost.
