"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. It's obvious to me that customer service and satisfaction is at the top of their priority list and it resonates througout the organization. Although I experienced a very minor issue with the initial diagnosis of the problems my property was having, I wouldn't hesitate to hire them again in the future and would recommend them to friends and family."

"Tony has not honored our agreement. I hired him to draw a new sewer pipe connection, 6 months ago, he told me it would take 3 to 4 weeks. I still do not have an acceptable drawing. Extremely disappointed with the unprofessional performance. Refuses to return calls or emails or produce usable drawings. Just has his assistant continue to make excuses because they cannot get the work done. Hire someone else that has integrity if you need any engineering done. Will be seeking legal action to get my money back."

Foundation Repair questions, answered by experts

Yes, you can fill cracks in concrete if you’re a somewhat handy homeowner. It’s important to know which concrete patching method to use, as small cracks require different approaches than large ones. It might seem challenging to determine which product to use and the tools necessary for the project, but with a bit of background, homeowners can restore their cracked concrete easily.

You can use a level or straight-edge to test for plumb foundation walls and a level slab, a level or a ball to check for sloping floors inside your home, and a hygrometer to look for moisture in your underhome area. Aside from these DIY tests, it’s important to get a foundation repair specialist or structural engineer to test the foundation to see if it’s supporting your structure properly. They can determine if the loads on the concrete are uneven or need reinforcement.

Yes, you can replace a cinder block foundation. If a block foundation is too severely damaged to repair cracks and other issues, replacing the entire foundation is a viable option. The job will require a professional and can take between one to seven days on average to complete, depending on how complex the problem is.

Water damage to a foundation often starts as a slow leak or water vapor problem that worsens over the course of months or even years. The speed at which foundation leaks worsen depends on a few factors, including your climate and location, the soil composition around your home, the foundation drainage system you have in place, if any, and the type of foundation you have. Even if you have a minor issue that’s slow to develop, it’s best to have a professional address the issue immediately.

The best solution to fix a foundation crack in your basement floor depends on the underlying cause. If you just have hairline cracks from settlements that are no longer growing, the best option is to seal them with a crack sealant. If the cracks continue to grow, one edge rises above the other, or there are signs that water is getting in through the crack, a professional repair will be necessary. Depending on the root cause, your professional may employ foundation underpinning or some other type of stabilization, seal the cracks, or install a drainage system.
