"Moises and his crew repaired water rotted wood in difficult locations and completely finished the garage to every detail from insulation to molding, as shown in pictures here. They thought of every detail that shows their pride over their work. Not only is their work top notch, but they are also easy to work with and very communicative through the whole process. I have already hired them for a second job."

"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!"

"Artie & Mike are simply the best. I used them to: 1) Build a LARGE extension to my house and redo my entire kitchen and dining room. The job was completed on time and on budget. Throughout the process Artie was transparent & professional. EVERY person who has stepped into my house has complimented at the detailed perfection. 3) Artie built us a custom walk in pantry 2) Built 2 large decks in the backyard as well as an outdoor shower. This project was completed on time, on budget while exceeding all expectations. If you are looking for a contractor and crew that is responsible, responsive, polite, creative and delivers the HIGHEST LEVEL of quality - Artie is the one."

"First off I live in Queens not Long Island..I got Metro Home Improvements number from someone who used them.. I called Romeo to set up an appointment for an estimate. Not only did he return my call within 15 minutes...he was at my house in Queens within 2 hours...now anyone who would do that gets high a mark from me. Over the years dealing with contractors none had ever responded that quickly...I hired them and I did not regret it. Romeo may have regretted the quote he gave me. My deck isn't big but does have quite a few angles involved and two sets of stairs.. They ripped out the old deck I had for 23 years and reinforced the base structure and started installing the new composite decking on day one ...day two job was completed. They were prompt; curtious and above all neat. I would definitely recommend Romeo and Metro Home Improvement. You will not ne disappointed..Five Stars ...If I could give Ten stars I would..."

"The roof of my metal shed collapsed during the last big snowstorm. I called several companies for estimates and Ben came same day right away. We spoke about options, he explained what needed to be done, and how he would proceed, He was detail oriented and knowledgeable. I felt comfortable with his approach. I highly recommend Dynamic Exteriors! The final product is a very strong, well built product that will withstand any storm for years to come!! Thanks Ben and Cesar!!"

Barndominium Builders questions, answered by experts

The pro you need to hire to build your shed depends on the shed you purchase. A local handyman or general contractor can help build a prefab shed for you. However, if you’re looking for a custom shed, contacting a shed builder near you is the best option. Make sure you get quotes from 3 pros to decide on the best pro for your job. 

This answer varies based on where you are, but most states require that all homes are greater than 320 square feet. Remember that four walls are not the only requirements—windows, closet space, minimal ceiling heights, and indoor air quality are also factors. Each state and municipality differs, though, and as some don’t consider tiny homes permanent shelters, you’ll need to check to ensure you aren’t violating any local or state laws with your build.

Pole barns and carports are similar in that they rely on posts for support and are often not connected to a primary structure. The main difference between the two is that pole barns usually include walls that surround the entire perimeter of the structure, while carports generally remain open on three or four sides. It’s possible to insulate garage doors and even exterior walls on pole barns to create a comfortable workspace, and it’s a bit more secure for storage purposes. However, carports are more affordable.

Rather than using a common two-by-four piece of wood for a rafter, you probably will use two-by-six, two-by-eight, two-by-ten, or even two-by-twelve boards. Wider lumber is typically a better choice in a larger building as it provides more sturdiness. Some installers may use wider lumber for rafters near the edges of the roof, where the greatest stress occurs, and save money with narrower lumber toward the middle.

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.
