"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"I needed stucco repair work on an old chimney (and other spots). Grady was meticulous and thoughtful on what approaches and materials would work. Throughout the project they allocated sufficient time for each treatment to cure and inspected the work before proceeding to the next step. Grady started the project with no money down and only required ongoing payments for materials until the project was well underway. The final payment was due only after they did a final inspection. Total project cost was also below other bids."

On the appointment date, Anthony conducted inspection of problem walked around the home & examined the problem window well and basement wall. We recently had the job done. We were amazed watching them work. They did a beautiful job in a very very tight space (see pics) They cleaned up the area when finished. We are very satisfied with the process. Starting Anthony’s expert advice to the gentleman who did the work..The new well looks great. Thanks Again Anthony & AM Shield!!

"We called Ed soon after we moved into our home, and became aware of multiple issues present within the house. The issues included several cracks in the Concrete Foundation of the Basement, an ongoing problem with High Basement Humidity, cracks and loose mortar around the bricks of the wood burning fireplace, and cracks in the tiling of the Center Hall Foyer. Ed came over right away, was able to measure the level of humidity in the basement walls and floors to determine the severity of the problem. In addition, he was able to point out several major contributing foundational issues. He determined the root cause of these issues and provided a solution that would prevent further damage to the structural integrity of the home. Ed was able to design a plan to correct the deficiencies both inside and outside the home which included insufficient and compromised footings, a sinking foundation, a failing support structure to the basement staircase, improper waterproof coating on the basement floors and walls, and stress cracks in the foundation walls. Ed’s Team worked diligently and installed multiple footings to stabilize the foundation, including rebar, hydraulic cement, wire lathing and titanium strapping to provide maximum support and stability to the foundation of the home and garage inner wall. The team built scaffolding to reach the height of the exterior chimney and rebuilt the compromised chimney footing, cracks in the chimney shoulder, and detached flu. On the inside his mason repaired the facial mortar and gaps between the chimney and the wood flooring. Ed’s Team was in my home for nearly 2 weeks working to correct these serious issues. The amount of digging and handling of heavy construction equipment they had to utilize was massive. They all worked tirelessly and went above and beyond. They were courteous, productive, and did not impact my daily activities of life during that time. They meticulously cleaned all the areas and left no debris. We were so pleased with their attitude and work ethic. Ed is knowledgeable, meticulous, patient and great at what he does. He provides the utmost of care to be sure his customers are educated with regard to the problem, the solution and the plan he will execute. He truly cares about his customers concerns and insures that they are satisfied with every aspect of the job. Ed will do whatever it takes to achieve that end. He invests himself one hundred percent in the job. This is an honorable business man that you can rely upon to stand by his company’s work. We highly recommend Ed’s Services for Foundation, Chimney and Moisture related concerns. You will have peace of mind knowing the job was done right and will look for opportunities to hire him back."

FAQs for concrete foundation repair projects in Oyster Bay, NY

Visible cracks, water leaks, uneven floors, or walls that won’t line up are classic red flags. You might also notice sticking windows, doors that no longer latch, or exterior cracks crawling up brick or siding. Even a damp, musty basement can hint at trouble. If you spot any of these, call a foundation pro right away. Early inspections cost far less than waiting until the damage threatens your home’s stability.

Yes, foundation problems impact your home’s value. Buyers want proof that the foundation is stable, and a recent, professional repair can actually boost confidence in your home. You’ll need to disclose the work, but documentation showing the structure was properly stabilized, especially with piers in regions known for shifting soil, often reads as a plus, not a problem. Skipping repairs, on the other hand, can cut your sale price and shrink the pool of interested buyers. Taking care of the issue protects both value and peace of mind.

Foundations are engineered for exceptional longevity when constructed correctly and maintained diligently. Concrete slab foundations remain structurally sound for 200 years, while other foundation types deliver integrity between 75 and 100 years. Regular professional inspections and timely maintenance further secure a foundation’s lifespan and ensure your home stays safe over the long term.
