"The consultation went great. Cary came out and spent about an hour measuring and evaluating our basement. He left me with a quote the same day as well as my options. Although a little pricey we decided to go for it. The guys came out a few weeks later to insulate and were here all day. No issues there. However, the basement has not warmed up since and we spent quite a bit of money and were told it would be about 60-65° down there. It only increased by maybe 5° and still isn’t even close to 60/65°. I emailed the guy Cary who came out and was told he’d talk to his guys about it. No response. I had to follow up. Then he said he’d send someone out. Never got a call or anything to schedule it. Again I had to reach out. Weeks later he finally said he’d come out on 3/18/21 at noon. It’s now almost 1pm and he’s still not here. Their service was great when they wanted our money but now that we have paid, it seems we are not longer a priority and they don’t care to come fix whatever the problem may be. Very disappointing. We spent thousands of dollars and our basement still feels very cold!"

"I needed to repair some foundation cracks at my home and Andi smart renovation did great job. First they cleaned out the crack area completely removing all dust and loose concrete. Then they opened the crack slightly to make sure the repair matrial could go deep inside for a solid bond. After the repair cured they waterproofed the area with foundation coating to prevent moisture from coming through again. Everything was done carefully and professionally from preparation to cleanup. I recommend them for any foundation repair work they know exactly what they?re doing and take pride in doing it right."

"Jon is professional and a man of his word. My wife and I had some leakage in our finished basement. After substantial research, I contacted several companies in the area. Jon and his crew at Eastern responded faster than every other company and offered us the best price for the least hassle. The crew works hard and fast. They were respectful of our home and property and cleaned up after themselves when they were done working. Our interior foundation drain is working great and can sleep in peace knowing that our basement is dry, even on the wettest nights.They stand by their work and even came out to install a false floor under our oil tank after we replaced it., at no additional fee. I would 100% recommend Jon and his crew for all of your waterproofing needs."

Foundation Repair questions, answered by experts

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.

A slab-on-grade or slab foundation is a great option in many areas—usually in warm or moderate climates—and has been a successful foundation style for many decades. Slab foundations don’t require excavation or concrete block wall construction, so they’re the least expensive foundation type. They’re also the fastest to construct and don’t have many issues with moisture or water intrusion. However, they don’t give you extra storage space or potential living space like a crawl space or basement would, and they’re not ideal in colder areas where utility lines can freeze and frost heave can cause major damage.

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.

Not all cracks in the basement floor signal foundation problems. As the house settles, you’ll notice very thin hairline cracks, which you don’t need to worry about. Cracks that are 1/8 inch or wider should require sealing, while ones that are 1/2 inch or wider require leveling. However, if you have cracks in your basement floor with heaving, you should call a pro to assess the situation. Heaving can lead to uneven flooring, structural issues, and foundation problems.

Yes, all basement floors crack in response to the natural settlement of the soil around them and from concrete shrinkage as it cures, and you’ll see hairline cracks as a result. However, you should keep an eye on your basement floor to see if cracks continue to lengthen or widen or show signs of water intrusion. In any of these cases, the problem is likely not settling or shrinkage, and a professional repair is necessary.
