"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 can use a variety of wood to build a barn door, but the most common options include 1-by boards and 2-by boards for the backing and the decorative boards on the front of the door. Softwoods like pine will save you some money and should hold up well, while hardwoods like maple and oak will stand up to more wear and tear. You could also build the backer out of plywood to minimize the cuts you need to make. Whatever you decide on, make sure the width of the wood is compatible with the mounting brackets you buy.

Choose a barn door with an extra two to three inches on either side of the frame. The width of the barn door will depend on the type and placement of your track, but in most cases, an additional inch or two will do the trick.

Building a barndominium means converting a barn into a house. Barndominiums are becoming popular as spacious and stylish alternatives to typical housing structures. Old barns that become houses traditionally consist of wooden construction. However, newer structures, such as pole barns, often contain metal exteriors and roofs. Converting a metal outbuilding into a house presents an excellent opportunity to create a barndominium from metal.

While it’s best to have access to large, healthy, strong trees in a safe position, treehouse living is still possible without them. Contractors can fit tree posts to build the structure onto or use posts as additional support alongside the trees themselves. If you’re in doubt about the suitability of the trees on your land, consult with a local treehouse builder before you start the project.

Whether it is better to buy or build a chicken coop depends on your priorities, primarily cost versus time and effort. Building your own chicken coop can be significantly more budget-friendly, often costing about half as much as buying a pre-made one. If you have the time and skills, building a coop from scratch is the most economical option. However, if your time or skills are limited, buying a kit and hiring a handyperson to assemble it can be more cost-effective than hiring a carpenter to build a custom coop from scratch. If you want a perfectly constructed coop without sacrificing your own time and energy, buying one is the easiest choice.
