"I hired Tim to fix a banister and put up various shelving and picture frames in my home. He was prompt, easy to work with and did a fantastic job. His prices were very fair and reasonable for the excellent work that he did and I will be sure to hire him in the future for any upcoming projects."

"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."

Customers say: True professional

"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."

"If there was a 10 star rating, I'd give him 10 stars! He was prompt and very professional. He rebuilt my old deck in one day and it came out beautiful. I wasn't able to be home and he kept me updated with the work he was doing and sent me pictures. When I ran out of material, he drove 20 minutes to pick up what I needed. He finished in one day and left the area immaculate. Highly, highly recommend."

Treehouse Builders FAQs, answered by experts

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

The quickest way you can protect plants and trees from frost is to cover them with garden blankets or frost cloths. Also, bringing potted plants or trees indoors is much simpler than trying to cover and protect them outdoors. Remember to anchor blankets with something such as sandbags, fabric pins, or rocks if the forecast calls for strong winds to keep them from blowing away and exposing your trees and plants.

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.

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.
