"John was terrific. Even though this was a very small project (moving some drapery rods), he was careful, professional, and very personable. I would definitely call him again when I need help with another larger project. I would highly recommend him to anyone."

"Hector and Moises were excellent! Hector came with one other of their crew and assembled my permanent gazebo. I have stone pavers and they were very careful in cutting them and digging Deep enough to establish a good anchor. They even installed railings for my back stoop. I would highly recommend them! Clean... affordable and professional."

"We had 2 storm doors that blew off their frames and needed repair. The team from CG (Carmelo and Giancarlo) were pleasant, professional and hard working. They did a great job and I would highly recommend them. They were neat and made sure the doors worked correctly before they left."

"Artie & Mike are simply the best. I used them to: 1) Build a LARGE extension to my house and redo my entire kitchen and dining room. The job was completed on time and on budget. Throughout the process Artie was transparent & professional. EVERY person who has stepped into my house has complimented at the detailed perfection. 3) Artie built us a custom walk in pantry 2) Built 2 large decks in the backyard as well as an outdoor shower. This project was completed on time, on budget while exceeding all expectations. If you are looking for a contractor and crew that is responsible, responsive, polite, creative and delivers the HIGHEST LEVEL of quality - Artie is the one."

Treehouse Builders FAQs, answered by experts

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

In most cases, you can attach a greenhouse to any type of house. However, certain factors need to be considered, such as the structural integrity of the house, available space, and local building regulations. You should consult with a professional contractor or architect to assess the feasibility and ensure proper construction methods.

Don’t forget to factor in the climate where you live during the planning stage. If your area is prone to bitter cold and heavy snow, you might want to invest in stronger greenhouse materials like a concrete slab, steel frame, and glass walls or plan to take your greenhouse down for the winter.

Sustainable materials and energy-efficient designs support greener construction options.

This is a personal choice, but if you’re in a hurry to have your garden up or feel overwhelmed by all that goes into choosing the right hydroponic garden, a professional can help you quickly get started. However, if you’re an avid DIYer, then you might prefer installing a hydroponic garden on your own.
