"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!"

"If you want the job done right the first time, Spencer is your guy! He had an excellent response time, was very professional, and came fully prepared with all the tools needed. He even made helpful recommendations that saved both time and money. I’ve since rehired Spencer for additional projects and highly recommend him. Don’t let your projects sit unfinished—Spencer will get them done right."

"Set and his partner are willing to take on, investigate and solve complicated non-standard problems across a wide range of areas. They come up with high quality and complete solutions that many contractors specializing one particular area would not be capable of. They've done a number of different projects for our family at two locations over the years. This includes * Renovation of angled flat roof, which involved replacing a large water damaged section with new rafters, fascia and roofing materials, * Complete remodeling of bathroom, including installation of wood tile flooring in bath and hallway * Solution to a hidden sewer line issue, that required troubleshooting both under the house and of the outside line to the street. Replacement and repair all damaged areas * House siding repairs and replacement due to water damage * Multiple other small repairs both inside and out. They bring a complete set of quality tooling and equipment to the site as required for the job,"

Treehouse Builders FAQs, answered by experts

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.

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.

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.
