"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."

"APD was on time and a good price. Unfortunately, they pumped too much foam in an area that caused substantial damage to my deck. Instead of taking responsibility, they blamed it on me. I would have been better off not hiring them at all considering the damage they left behind. When I reached out to them, neither owner could be bothered to even speak to me personally. I asked them if they would file a claim with their insurance company and they turned that into me wanting money. I just wanted them to take responsibility for causing the damage and then fix it. I would not hire them again!"

Foundation Repair questions, answered by experts

Yes, you can live with a cracked foundation—in fact, most people do. Virtually all foundations crack from normal settlement, and while settling cracks benefit from sealing to prevent water and moisture intrusion, most aren’t an issue. If you have structural cracks in your foundation, it might be safe to live in your home for some time, but you should address them immediately to prevent structure collapse and major property damage.

While it can be difficult to identify a bad foundation at first glance, look for large horizontal cracks, discoloration, bulging basement walls, or signs of water damage. You may also see large gaps between the home and the foundation on the outside or signs of pooling water from a recent storm.

It can be safe to live in a house with minor foundation problems as long as the issues are checked and monitored by a professional. Minor cracks are rarely a cause for structural concerns, but signs of leaks, sinking, or bulging walls should be strongly scrutinized by a foundation specialist. Similarly, it's always smart to hire a professional when you're concerned about buying a house with foundation repairs.

Yes, it is normal for a block foundation to crack. Some block foundation cracks are more serious than others and indicative of a larger structural problem. On the other hand, minor cracks may not be of immediate concern but should be monitored. Regardless, foundational cracks are not an uncommon response to wear on a structure from time and weather.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.
