"Josh is professional, on time, and willing to do the extra mile to do the job right. He is up front and honest about pricing. Would trust him to repair or install anything if I needed it in the future."

"Professional staff. Steadily working, minimal noise and/or disruption to daily activities. They answered all questions and addressed any issue, no matter how small, with the project. My new front porch is just what I wanted. Quality work! I hope to hire them again in the future."

"Work agreed to: 1) level a slope, 2) build stone patio, 3) install fence. Period of performance told by the contractor was 5 days to a week and a half. Work started May 16. By June 3 project was not half complete. Contractor delivered pile of dirt and pile of gravel and railroad ties for retaining walls. Contractor did some work. If reasons given were accurate, then some missing days for medial were reasonable but after three weeks there were several issues: 1) the work was only about halfway complete after three weeks, 2) the slope remained which can't be used since it's needed for a shed, bee hives, and raised beds, 3) the rear retaining wall was already leaning and losing dirt from only one rain. With these concerns I consulted two other landscapers who immediately identified problems with the wall as well as the slope, that it would not hold through one winter. In addition, contractor may not have contacted Digsafe, public utilities, and city public works for permission to proceed with any excavation. I have a lot more details including inconsistent texts"

"Everything went wonderfully with this company.  They were very professional, listened to exactly what my problem was, and explained to me how they were going to diagnose the problem and/or solve it before doing any actual work.  Once they started, the team (three people came) worked together like a well-oiled machine.  One was in the room with diagnostics, one was at the fuse box looking for possible problems there, and the third went into the crawlspace beneath our house to look at the physical wiring.  Once the problem was found (there was a faulty wire beneath the house that had come loose from the junction box), it was fixed and tested within minutes and another full diagnostic was done to make sure there were no other possible issues.  They cleaned up after themselves very neatly.  They also replaced the light switch with a dimmer switch at no extra cost!  Well within my budget, and came in even lower than their original (FREE) estimate!  I would highly recommend this company to anyone in the Bergen County area.

"I’ve worked with Jared Rice and True North on several projects over the last few years. The most I could ask for is good communication, dependability, and quality of work and I’m never disappointed. He also has a great group of subs that make all of our jobs run smoothly and timely- all things that can make or break a renovation and a budget. This is sometimes hard to find in my industry. I’m hesitant to rate because I’m afraid he’ll be so busy I won’t be able to get him when I need him! I wouldn’t be able to do what I do without Jared and his team along side me."

"Nathan was very professional and listened to what I wanted for my bathroom remodel. He finished in a timely manner, and he always kept a clean work site. The one negative was that I had water leaking from the newly installed toilet and sink pipes within a week or two due to an error in installation from one of his crew (according to him). I had water ruin the drywall in the basement bathroom below the newly renovated one. I was obviously not happy about this, but Nathan quickly responded and was more than willing to have someone come and fix the drywall and repaint the downstairs bathroom wall that was damaged with no cost to me. I would have given him 5 stars if this had not happened."

FAQs for shed, barn or playhouse building service projects in Winthrop, ME

Barndominiums cost $50 to $200 per square foot (or $65 to $160 per square foot for finished living areas). You’ll pay even more for a larger barn house. This project costs more than the typical barn construction because you’ll need elements like a kitchen, bathroom, and finished living spaces. Building a barn house is comparable to building an actual home.

A high-quality barn lasts 40 to 60 years when built with robust materials and maintained with dedicated care. Quality construction practices and a strict maintenance schedule ensure that key structural components, such as support posts and roofing, remain effective for more than 60 years. This long lifespan offers homeowners sustained functionality and reliability over time.

The project type determines the construction timeline for a barn. A standard pole barn finishes in six weeks, a traditionally framed or steel-framed barn concludes in four months or more, and a barndominium takes six months or longer due to the extensive design, electrical, plumbing, and finishing details. This schedule ensures each phase is completed efficiently by qualified professionals.

When planning to construct your barn, it's important to review local building codes and zoning regulations. These regulations may include guidelines on building height, property boundaries (setbacks), lot coverage, and easements. Understanding and complying with these requirements helps ensure your barn is built safely and legally and avoids any permitting delays.
