"Wonderful communication from day 1. Very pleasant to work with and Very professional. My wood deck was in bad shape and needed to be repaired, power washed, stained and sealed. The job was done with care and knowledge and done very well. The deck looks great! I highly recommend Star Dynasty and will use them again when I need work done on my home."

"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."

"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."

"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

It is almost always more affordable to buy an existing home than to build a new one. Building a home involves numerous costs, including labor, permits, inspections, utility hookups, and brand-new materials, finishes, and appliances. Additionally, new construction loans can have higher interest rates than traditional mortgages, and property taxes on new homes are often higher, increasing long-term costs. An exception is a DIY house build, which can be cheaper than buying an existing home if you do the labor yourself. While building is generally more expensive, a new custom home offers complete control over the layout and design. Furthermore, new construction is typically worth more than a comparable pre-owned home and may provide a better return on investment if sold quickly.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

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. 

Depending on your needs, you may find a storebought pole barn is a much less expensive option than a custom-built one. You can find pole barn kits from big box retailers starting at $11,000, but you will be limited when it comes to size and add-on features. As long as you have the necessary skills, you can save on labor costs by doing it yourself; but there are a lot of different skill sets you would need, and mistakes during the building process can lead to excessive repair bills later.

Whether you should choose a flat roof or a sloped roof depends on your particular situation. Flat roofs tend to be less expensive to install. However, sloped roofs have longer lifespans and stand up better to heavy snow and other inclement weather.

Keep in mind that even a flat roof needs to have a slight slope, usually around 1/2 inch for every foot. If it is completely flat, water will pool and cause damage, either from weight or leakage or rot.
