"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."

"Elson did an excellent job removing an old crumbling entrance to my house. He installed new poured concrete stairs and a side walk. They are much safer and look great. I would not hesitate to hire him again in future. He is friendly, competent and reasonably priced."

Foundation Repair questions, answered by experts

Yes, it is worth repairing concrete cracks. Concrete cracks are normal, and they can be hard to keep from appearing. However, it is worth repairing cracks in concrete for many reasons. For example, it’s possible to repair concrete to the point where the repair is almost invisible. Also, if the crack is left alone, it can become bigger and more expensive to fix over time.

Addressing gaps and cracks reduces heat loss and improves energy use.

In order to raise your home to make foundation repairs, you'll need to bring in a structural engineer to help you design the project. You'll also need to see if you're eligible for the permits needed, and contact a foundation repair company near you.

Not all cracks in brick indicate foundation problems. For instance, small hairline cracks can occur as a new construction settles. However, larger cracks are often a sign of a more severe issue. Indicators of a potential foundation problem include long horizontal cracks, "stair-step" cracks, vertical cracks that appear indoors, or any crack that widens at the top. Other signs of structural damage to look for are uneven floors and doors or windows that stick. These issues could be caused by problems with the soil beneath the home or an overgrown tree.

It depends on the bank and the extent of the issue. Some banks will lend against homes with minor foundation damage, but most won’t if the issue is structural since the home acts as collateral for the mortgage. Banks that offer renovation loans might still finance a home with structural problems. More minor issues like settling cracks and intermittent problems with humidity are unlikely to stop a bank from financing.
