"This is a follow up to my prior review of Alpha Foundations. After reading my initial review, Alex (The General Manager) conctacted me to chat about my experience. I left the conversation with a better understanding of the initial inspection process and thoroughly impressed with the overall customer service of everyone I came into contact with at Alpha. From the sales team, field techs and management, my customer service experience was top notch.

Jim Rutherford Construction & Remodeling LLC
Jim Rutherford Construction & Remodeling LLC
We will perform any type of residential construction, repair & remodeling services in the lower Florida Keys.
"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."

"Reliable Claims Adjusting provided invaluable assistance, ensuring that our insurance provider paid an appropriate amount based on our policy and the loss we had experienced. When we first filed our claim with the insurance company they tried to deny it completely, which was really frightening. Andrew with Reliable Claims Adjusting explained the whole process of working with a public adjuster, and ultimately was able to secure funds that should cover all of our needed repairs. We are incredibly grateful!"
