"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

The steep slope of an A-frame roof withstands high winds, heavy rain, and heavy snowfall, making them popular all over the world. A-frames also offer simple, quick construction. Finally, an A-frame typically has large windows on the non-roof sides to let in a maximum amount of natural light. Consequently, they are often an affordable building solution for the right homeowner and location.

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.

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.

Whether pole barn posts should be set in concrete depends on the soil surrounding your home. If your soil is compact and digging conditions are agreeable, then setting pole barn posts in concrete is an ideal option.

It is recommended that you check with your local building official on barn building requirements and rules, since size restrictions vary greatly from region to region based on what your property is zoned for. Some cities limit barn construction depending on if your property is residential or commercial. The three main factors your building commission will evaluate are:

  • Height and lot coverage: How tall your barn is and how much of your total property it occupies

  • Setback: Distance between barn and property line

  • Easement: Legal right for another owner to access another’s property
