"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."

"Knew what was needed to be done immediately. When i hire someone for a project i hate being talked down to or not having something that i may not know explained clearly. This was not the case at all with Mr. Handyman of Huntington. They were friendly and explained everything that had to be done very plainly. I really appreciated the straightforward, no BS approach. They finished quicker than expected and even came in under the estimate! Another plus, of course. Lol. If you are looking for someone to do a project around your house, i cannot recommend Mr. Handyman enough. As you can probably guess at this point, i was extremely pleased with the job they did putting up my shed and wouldnâ t hesitate to hire them again."

Treehouse Builders FAQs, answered by experts

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.

The choice is really yours. Greenhouses available in kits can make the job go quicker. You can find greenhouse kits to match your style and size needs. If you enjoy designing and planning, you can build your own from materials of your choosing. Just be sure to do your research beforehand so everything ends up structurally sound.

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.

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.

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