"This job was done in February 2017. I just discovered I never finished writing the review. So here it is 3 years later. First, doing this review now lets me tell you that our new metal roof made it through Hurricane Michael with flying colors. We had other storm damage ($25,000 worth) but the roof did fine. The job was done on schedule though interrupted by two afternoon heavy rain events. First class installation by a team that showed up on-time each morning, worked hard and got along well together. They were proud of their work and and cleaned up the site when done even using a magnetic sweeper to lift any roofing nails that might have fallen. The roof we chose was white which made our house really stand out over the gray siding and white trim. Moreover, our HVAC bills were lowered (I track it). Last, I want to tell you that Guyson are more than just roofers after your money. They are fine local people. Recently, my 94 year-old neighbor climbed on his roof to do some repairs. He fell off the roof onto a concrete pad and spent 5 days in intensive care. 20-some staples in his head, boot on his left leg and badly bruised ribs but super lucky to be alive. Needless to say, he's not going to get on the roof anytime soon. I get "the cat claws" when I'm on a pitched roof. So I called Guyson and when they heard the story they came out and looked at the job. Although they are swamped and this is a small job they're gonna do finish the repair anyway. God love 'em. BTW, my neighbor's fall is how I found out I never finished this review I started in 2017."

"2020 has passed and we couldn't be happier with our completed first floor project, thanks to Jim Rutherford Construction. Jim was willing to tackle what other local well known contractors were either unwilling to consider or bid so high as to be unaffordable. Our project proved to be a technical challenge from the onset, raise the ground floor by almost a foot of concrete, completely rebuild the first floor by installing 3 impact French doors, 3 impact doors and 4 impact windows, cut off support an internal staircase including modifying framing around a dumbwaiter, reframe and replace every exterior wall from 4' down. Plus an added surprise rebuilding and repairing 45' of a heavily spalled concrete tie-beam in less than a week. We're still amazed at how quickly and confidently Jim set about taking on the project, he seemed to have it figured out before we even committed to getting started. He knew just right carpenters and subs to assign the work to. Once they began, they never stopped till the project was completed. Workmanship was outstanding, inspections were a breeze. I commend Jim and his crew for the quality of work and attention to detail, no shortcuts taken, stainless hardware/fasteners throughout and only pressure treated lumber. Add them all up and we have a completely new remodeled permitted downstairs ready to withstand the elements. It is without hesitation we'd recommend Jim Rutherford Construction for any project or home construction. Professional, polite and a pleasure to do business with."

Home Building questions, answered by experts

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits. 

As long as you pull the appropriate permits to build your ADU, it will contribute to your property’s total livable square footage. This is even true for basement conversion ADUs despite the living area sitting below grade. Keep in mind that permanent improvements, especially those that add square footage, tend to increase your home value, which can affect your property taxes.

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand. 

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.

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.
