"East Coast Concrete or East Coast Contracting. Contractor Jack. Our last conversation I promised I would send in an unfavorable review if I received no communication and no progress. So I guess ECC does not value its' reputation. In a nutshell. ECC was contracted to repoint a 3-story rowhouse. To say progress has been slow would be an understatement. Contract was signed and approved on June 26, 2025. December 17, 2025, 6 months later I am still waiting for word, a completion date or any interest in completing this project. The job was basically left in a stand still, after the first visit. I was left with an industrial size bag of garbage in front of my home. A friend informed me a rat was scrounging around the bag. And yes, one was inside my house. I had to pay 1.800.Got Junk to remove the bag. Numerous texts, calls, pleas and for the most part of I have been ghosted. My last text was on November 20th. Angie if is this is how you run your business, I want no part of it"

"I hired JES to install a trench and sump system into the basement of a new house I purchased. After the job was completed, I noticed the cellar stairwell was pooling water. They returned and said that they didn't think that the drain was run direct to the sump as it should have been but they needed to open the concrete to verify. I also asked why there was no water in the sumps. They ran tests with water for 2 hours and didn't see water and tried to explain to me that it was expected since the water was running out around the drainage under the foundation. They even had a supervisor try to explain to me over the phone when I questioned it. It took them several weeks to return to fix the cellar drain and sure enough, the pipe was just run to under the foundation and not directed into the trench/sump. A repair team came out and busted up the concrete to correct it. In doing so, they saw that their trench was also not connected to the sumps at all, which is why I never saw water in the sumps and not the mysterious theory they tried to convince me of weeks prior. This is terrible that there is no inspection of work prior to covering it totally with concrete. Or further, there was no physical test of running water in the system to verify the sump works. The repair team that came out were wonderful and did everything correct. After this, I called 3 times and asked for a manager to call me to discuss this and never received a response. The salesman stopped answering my calls. As a note, after spending $30K on this upgrade to my house, it was in worse risk than prior to JES so if you choose them, be careful."

Foundation Repair questions, answered by experts

No, hairline cracks in concrete are generally not a problem as they do not impact the strength and longevity of the concrete. Generally, cracks less than 0.3 millimeter wide don’t impact the structure. Hairline cracks can grow over time and weaken the structure, such as in a home foundation. Some hairline cracks can also cause leaks in a foundation. It’s important to watch the cracks to see if they grow. Contact a concrete contractor if you notice cracks exceeding 0.3 millimeter wide.

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation. 

Always hire a foundation repair contractor the moment you suspect your house doesn't have a good foundation. The longer you wait to address foundation issues, the more likely they can lead to bowing floors, cracks in walls and ceilings, sticking doors and windows, chimney and roof problems, and more. Foundation problems can also let moisture into your home, leading to water damage, mold, and mildew problems.

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.

You have different options depending on the scale of repair needed. If you are repairing minor cracks that are between ¼ inch to 1.5 inch wide and less than half an inch deep, a self-leveling polyurethane sealant would be your best choice. Polyurethane sealants dry to the touch within one to two hours. Since they come in a tube applier, you also have the option to complete the repair without emptying out your garage.
