"Juan does it all! He remodeled my kitchen and did everything but the countertop installation, but was there to supervise and inspect their work and because he is bilingual was able to communicate with them more effectively than I could. He is very conscientious and does excellent work! Because he does it all you donâ t wait on other subcontractors . I highly recommend Juan of North South East West LLC"

"Jordan is very professional, does fantastic work and always takes the time to the clean up the project area at the end of each work day. He is someone you feel comfortable having in your home. We had him remodel 2 bathrooms and more recently had him do a smaller job of adding brackets to joists in our very small attic area. He is always on time and clearly communicates the cost of the project. I highly recommend Jordan and Black Diamond Design Builders."

"Having experienced a homeowner's worst nightmare by one contractor, I contacted Jim DeCuzzi to rectify things based solely upon meeting him just one month earlier when he actually recommended against undertaking several minor/moderate sized projects in our home - believing the timing wasn't right (i.e., He was more interested in us rather than just collecting a paycheck - a rare trait in his field). Based on this experience I was impressed with both his technical competence to tackle our current large scale project (he's a walking construction/building encyclopedia), and even more importantly, the sense of integrity we were looking for in a contractor (never realizing I'd be calling him one month later). Having just completed 2 ½ months of renovations D&K proved to be everything a service company should be - professional, efficient, reasonable and most importantly trustworthy a company that respects its customers and places their interests first. Equally impressive was Jim's partner Steve Kessler every bit as technically competent and with the same sense of character to match. As the onsite supervisor, we couldn't have hoped for a more forward thinking or forward leaning individual to address the countless day-to-day decisions and activities inherent in coordinating all the efforts associated with restoring our home (electrical, plumbing, carpentry, drywall, painting, etc.) As with any project this scale, it was not without its share of unanticipated problems. Jim and Steve were quick to diagnosis the issues, recommend a solution and employee the necessary resources to rectify the situation (i.e., no wasted time evaluating the situation while racking up unnecessary labor charges). Both were especially empathetic to our situation keeping us current on all developments which was a huge relief in alleviating the stress of trying to manage all the unknowns from a distance (we live in Boston). In sum, Jim and Steve are a one-of-a-kind TEAM. They are exceptionally polite, personable, competent and knowledgeable with the energy, enthusiasm and sprit de corps to tackle anything thrown at them. As a Marine I especially appreciated their professionalism, sense of urgency and attention to detail. It is also obvious they approach their work not so much as a job... but as a profession... a refreshing change from the norm, which makes a huge difference in the end result/product. I only wish we could find more contractors with the same work ethic and sense of service to their clients. We'll obviously be engaging their services in the future, and if you're starting the search process to evaluate contractors, you'll save yourself a lot of time and energy starting with Jim or Steve great guys dedicated to their customers and with a truly remarkable gift for doing things right."

"Tyler and his team are super easy and pleasant to work with, they remodeled two custom bathrooms for me exactly the way I wanted and even made renders of them before it was done. They really made sure everything was perfect for me and worked with me every step of the process. Even when mold was found under the floors, the team at Mannis did everything in their power to make sure the mold was remediated, and the bathrooms were done correctly. Highly recommend if you want a custom bathroom!"

Treehouse Builders FAQs, answered by experts

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

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

The only real drawback to green building is that it’s more expensive up front, with per-square-foot prices sitting 33% higher than what you’d pay to build a traditional home. The higher cost is due to more expensive building materials and more labor to ensure every aspect of the home is as efficient as possible. However, green buildings often save money in the long run, so this is just a temporary downside.

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.

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