"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.

"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!"

"Quality Work By People Who Care" Remodeling, Framing, Drywall, Painting and more..... We Work Third Shift! Residential / Commercial. Licensed and Insured. 24 hours service. Free estimates provided (verbal)

"Dwight from Cornerstone Construction is the REAL deal! I am probably one of the pickiest people when it comes to contractors. I have never liked a single one, but Dwight is absolutely wonderful. They have remodeled our entire kitchen (removed our whole old kitchen and replaced it with a brand new kitchen including appliances, exhaust, backsplash, etc) - it looks perfect, which I NEVER say. I have no conflict of interest....I am tired of contractors who don't do a good job so when I found Dwight, I was ecstatic. I have used his company for the build out of my medical office and always refer our friends and family to him."

Foundation Repair questions, answered by experts

Foundation repair can affect home value positively or negatively. If you address the underlying issue and hire a foundation repair contractor to complete the work—especially one that includes a warranty for the work—then your repair will likely increase your home’s value. If you fail to pull proper permits and cannot prove that a licensed expert completed the work, there’s a chance buyers will view your home in a negative light and end up offering less for your property.

Most of the time, normal foundation settling will present as thin cracks in the foundation and minor creaks in the floorboards. In contrast, you can identify foundation issues by wide or uneven foundation cracks, horizontal or step-shaped gaps on the foundation wall, or cracks that go around corners of your foundation. Foundation problems can also cause changes in your living area, like increased humidity, uneven or sloping floors, nail pops in drywall, countertops pulling away from the wall, and windows and doors getting stuck. When in doubt, call in a professional to identify the underlying cause.

Regularly inspecting your foundation—at least the visible sections—for signs of foundation issues like moisture and pest infestation is a good way to identify slab leaks early, as is keeping an eye and ear out for water damage to indoor building materials, above-average water bills, sounds of running water when no fixtures or appliances are on, and indoor humidity that causes the temperatures to feel more extreme. If you do find any issues, contact a plumber right away to check it out for you.

It’s usually not an immediate safety risk to live in a house with foundation problems, but you don’t want to let those problems persist. Most foundation issues don’t lead to a house’s sudden collapse, but they can lead to health issues like mold growth and pest intrusion, as well as problems like uneven floors or rotten beams and joists, which can pose injury risks and be costly to fix.

Foundation problems are costly to repair, but if you already own the home, you can either handle the issues or allow the property to (literally) sink into disrepair. The opposite is true when buying a home. Walk away if the seller refuses to lower the asking price once foundation issues are exposed or if they refuse to handle the problems before the completion of the sale.
