"I recently had a new sliding patio door installed, and the experience was outstanding from start to finish.John and joe arrived on time, both of them worked efficiently without making a mess. They removed the old door carefully, prepared the opening properly, and installed the new unit with precise alignment so it glides smoothly and seals tightly. The door looks great, operates quietly, and has already improved the natural light and energy efficiency in my dinning room. My kids are like more sitting at dinning tablet during the day given the ambient light. Communication was clear throughout— He explained the process, answered questions, and cleaned up completely before leaving. The whole job was finished in time without delay as promised, John and his team show professional workmanship. Highly recommended for anyone needing a patio door replacement and any home improvement projects."

Customers say: True professional

"

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.

"I tried the Home Advisor reluctantly since I don't ever feel you get what you hope for... But in this case I went with Dynamic Exteriors and was really surprised at their response... I sent pictures to all that responded to me. Some had minimums to do the work but Dynamic Exteriors called me and told me they could come the same day 7pm. I was about to change it but I decided to just get it done. It was the best decision I could have made. Most reasonable price, excellent work and good attitude and friendly to talk to. I'm one that likes to watch and learn, he knew exactly what to do no time wasted, done quickly and cleaned up. I'm happy; I to highly recommend them."

Barndominium Builders FAQs, answered by experts

You don’t typically need a permit to build a shed, but it’s best to check with your local city clerk to make sure before you start the project. Every town, city, and municipality can have different rules when it comes to any home improvement project. Homeowners associations sometimes have restrictions on the materials you can use on your property as well.

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.

Whether you buy a prefabricated shed or build one depends on why you need it and where you stay. For instance, if a simple garden shed is what you’re after, it’ll be less expensive to buy one already built. But if you want a shed with windows, plumbing, and electric work, a custom-built unit might be more suited to your needs.

Yes, you can use a storage shed several ways, including as a chicken coop, but you'll need to make some modifications. You will have to add a chicken door, roosts, ventilation near the roof, mesh on the windows, and insulation if you live in a colder climate. Additionally, you’ll want to ensure that the shed is predator-proof so no other animals can harm your chickens. You should also add a run and nest boxes to your shed.

In the U.S., original and converted carriage houses are most often found in New England, New York, and other parts of the Northeast. New construction carriage houses can be found across the country, and are often added to properties with Colonial-style homes for additional living, storage, or work space, although they can be found in many different styles.
