"We were extremely happy with the work performed by H&M. Moises, Hector and crew were courteous and did whatever needed to please us. They did most of the renovation in our condo......painting, installation of bathroom cabinets, sink, installed tile floor, etc. They also installed vinyl flooring in our kitchen, living and dining rooms. They had a plumber replace our heating baseboard, I would highly recommend H&M if you want excellent work done!!"

"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."

"

This is the 2nd major project I contracted Art DeRosa & Co for.  The 1st being 4 years ago a major living room/family room renovation which was hugely successful.  That 1st experience led me to award Art (after several other competitive quotes) this 2nd and far larger & more complex project.







Overall it went well but this was a complicated project encompassing all the typical trades and expertise of building a new luxury house but far more complicated because it was a renovation performed while we were living in the home. Dust partition walls with wood framing had to be erected in several locations in the house which included temporary doors for entering and egress in certain areas of the remaining living areas of the house in order to protect the remaining house from dust and demolition , as well as, provide privacy for us during construction. 

Experience, Experience, Experience and Professionalism, Professionalism, Professionalism are the hallmarks of Art DeRosa and company.  He is a seasoned performer and pretty much seen it all.  Art has such a vast amount of home construction experience in both hi-end and medium end homes that he can draw upon a wealth of knowledge in all construction disciplines to implement a fine finished result.  As a former tool and die maker his penchant for hi-precision finish work yields highest quality appearances to things like moldings; trim; windows; doors; floors; etc. etc. 

This complex renovation project lasted 7 months which was within the initial time estimate given at the beginning and Art DeRosa and team were here every single day, day in and day out,  bright and early during that time frame. He did not start any other projects and stayed on the job day-in and day-out even when other sub-contractors such as plumbers and electricians were on the job site excluding his people from doing any other work. Art DeRosa and team were here every single day until final signoff.

I would not hesitate to recommend Art DeRosa & Co for any planned New House and/or House Renovation of any kind.

"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."

"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."

"⭐⭐⭐⭐⭐ We couldn’t be happier with the work Manuel did on our house. He covered everything the renovation required- tile work, plastering, plumbing, electric, carpentry. The tile work is absolutely flawless, the baseboards were installed with great attention to detail, and the plastering on the ceilings came out smooth and professional. Everything was done with care, precision, and a clear pride in craftsmanship. He was reliable, punctual, and kept the work area clean throughout the project. Communication was excellent, and he made sure everything was done exactly the way we wanted. The house looks completely transformed, and the quality of work exceeded our expectations. Highly recommend to anyone looking for a skilled, trustworthy handyman. We will definitely be using him again for future projects!"

Treehouse Builders questions, answered by experts

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

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.

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.

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.
