Customers say: True professional

"Our kitchen remodel with McCormick Home Builders went beyond our expectations. Leoni and her team took the time to understand exactly what we wanted. The open layout design changed the way we use the space, and it’s been perfect for family gatherings. They were prompt, courteous, and genuinely invested in making sure we were happy. Really impressed!"

"Hi, Jeremy & Ian exceeded my expectations. They walked me through the process with a preview, Stellar performance on my closet finish that had collapsed. I was smiling at each phase of job & once the job was completed btw I had a permanent smile 😃.. I was soooo.. very happy with the high quality & very professional work performance that I must share with anyone looking to have a closet repair project done. I will be referring Jeremy & Ian both to friends & family ! If. I need any future home-related projects requiring a professional they will be my primary choice. Best, Arlana Hines"

"Daniel has done two projects for us where he assembled a large dining room table and large china cabinet both over ten feet long. His work was impeccable and he was professional and courteous. We got both pieces from Wayfair and the required intense installation with 100â  s of pieces. He has all the tools and went above and beyond to get it done. I would recommend Daniel for any type of handyman job"

Treehouse Builders questions, answered by experts

Increases living space and adds value to the home through enhanced utility.

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.

When designing an attached greenhouse, several factors should be considered. These include the orientation and positioning of the greenhouse to maximize sunlight exposure, the structural integrity of the connection to the house, sufficient insulation to regulate temperature, proper ventilation for airflow, and adequate space for plants and pathways. If you’re restricted because of your budget, go with a simpler design to maximize the use of your money.

Yes, with proper heating or cooling systems and energy-efficient glazing.

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.
