"Ivan and his crew were friendly, professional, and always on time. The work was completed to a high quality. I am so glad to have found this multi-talented handyman. The first job was to install new curtain rods and rehang curtains—perfect! Next, power washing entire house, windows, gates, painting exterior doors all the jobs on my summer wish list completed to perfection at a reasonable cost with a sunny bright smile and positive energy that lifts the spirit. Thank you Ivan—looking forward to working again with you again when the need arises!"

"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."

"John was great. We hired him to replace 3 doors on my ground level to help modernize my home appearance. The job wasn’t as simple as I thought but John reassured me he’d get the job done and that’s what he did. He was on time, clean workmanship and quick turnaround. Definitely will work with John Lang and his partner Joe on future home 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."

"Hired him to do a railing and install some doors and closets. Beautiful, meticulous work. They actually put on blue booties over their shoes, so clean. Communicative and fairly priced compared to other estimates."

"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

"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."

Small jobs welcome

"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 questions, 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.

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.

Painting countertops can take a few days to complete yourself. However, keep in mind that it can take up to 14 days for the sealer to cure. So, you want to make sure you wait the manufacturer's recommended amount of time before using your countertops after painting them.

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.

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.
