"I recently moved to a new home and needed help installing a mailbox. I reached out to Bill from Mason Carpentry and he was quick to respond and willing to assist. He came to my home only a couple of days later to install it. Bill was great, incredibly friendly and professional. As a new homeowner, I need all the help I can get and I will absolutely be using Bill again for other projects. I would definitely recommend Bill!"

"

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.

"We hired Tri Build to do a complete renovation on an old home we bought in Eatons Neck. It was a very unique project that took someone that could think out of the box and make it happen. Ray,the owner,designed a wonderful layout for us and executed the project with honesty and professionalism. We had alot of changes as we went along and he was extremely courteous and very fair on his price. He did a full service job. Tri Build's project manager Tommy, was a complete gentleman and fully accommodated our requests Demo, roofing, siding. They built us a beautiful front porch. This company was a pleasure to work with. We couldn't have done it without Tri Build. We highly recommend them."

Barndominium Builders FAQs, answered by experts

Due to the expansion of the tiny house movement, you can usually find tiny houses to buy in your state. Prices range considerably based on size, style, and type. If you’re looking for a tiny home that’s move-in ready, you may be able to find a good deal to buy or a prefab dealer near you. 

The foundation for a pole barn should be at least 36 inches thick to ensure that the piers won’t shift from frost heave.

A steel frame costs 10% to 20% more than a wood frame. Wood is a much easier material to work with, more accessible, and generally more affordable than steel—plus, you need specialized tools to work with steel.

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.

While building a treehouse isn’t necessarily a death sentence, damaging the trunk is one of the ways to kill a tree. If you’re concerned about the tree, opt for a treehouse support system rather than attaching it directly to the trunk. This may involve using bolts and brackets to affix the structure to the tree's branches or establishing a standalone support system that remains unattached to the tree.
