"Prompt return of calls and professional written estimate. They arrived on time and did a great job repairing the concrete patio. Then they redid the surface after scraping the old peeling paint. In addition, they went above and beyond to make sure everything looked good and cleaned the whole back patio of any debris! Overall a huge improvement and I can use my patio again! I would recommend them for a fair price, promptness and quality work."

"Very professional and fixed the cracks in the garage the best that I can tell. Expensive fix but well worth going with the carbon fiber, you get a 15 year transferable warranty with it. Only deducted half star because they didn't show up on a modified scheduled date."

"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

No, house settling is normal as your home’s foundation settles into the soil below and as the framing of your home shifts as it expands and contracts with changes in temperature and moisture. However, if you get to the point where your doors and windows aren’t opening easily, your floors are uneven, or you can visibly see that your roof line is wavy or uneven, you are more likely to have foundation issues.

If your foundation repair claim gets denied, the first step is to carefully read over your policy and denial letter so you understand the reason for the denial. Then, gather evidence and documents that can support your case and appeal the denial with your insurance company. If your insurer does not eventually honor your claim, you may want to file a complaint with the insurance department in your state. In some cases, it may make sense to work with an attorney and file a lawsuit.

It’s usually not a big deal if your foundation sinks between 2 and 3 inches into the ground after construction, provided the settlement occurs evenly. This is usually indicative of normal settlement that occurs as the soil under your home adapts to the weight of the structure. If the home sinks more into the ground or the settlement occurs unevenly, leaving portions of your home to sink further down than others, then call a foundation repair specialist to address the issue and avoid additional damage.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.
