"quality of work is good. One issue was they tried to change agreed upon price after work was completed, however, they did honor original estimate.

"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 am having a truly unpleasant experience with 7th State Builders. I paid 14,450.00$ deposit in good faith. They were contracted to rebuild my deck, place a roof structure and screen on the deck. I trusted that they would complete the work. Instead, they took my money and one year later had not even started on the project. Not only did they fail to perform the agreed-upon services for the deck, but I was forced to hire an attorney to try and recover my deposit. Which I haven?t yet (over one year). Thus, creating unnecessary expenses to an already frustrating situation. I would strongly advise against using this company. They are unprofessional, uncommunicative, unreliable and clearly not trustworthy. My experience currently has been a complete waste of time, money and emotional energy. Dr. CLARICE BROWN "

Retaining Wall Installers questions, answered by experts

To maintain the integrity of your landscape, a retaining wall must be installed if the slope of the angle exceeds 35 degrees. The lean of the wall must be 1 inch per 12 inches in height to disperse the weight of the soil uniformly and guarantee the correct drainage of the soil.

Generally speaking, a retaining wall should be between 3 and 4 feet high, depending on variables such as the wall-building material, the purpose of the retaining wall, and more. If you want your retaining wall to be taller than 4 feet, check with your local building ordinance office for the maximum allotment. You may also need a special permit for retaining walls over 4 feet tall.

Each design is different, so we can’t say definitively if you’ll need a dedicated drainage system in place for a two-foot retaining wall. However, you can likely skip the drainage, as this project is typically served for walls that are 4 feet tall or more. Even with a relatively low wall, consider drainage if you are building on top of clay or poor-draining soil types or if there are buried water sources nearby, like a well used for other outdoor garden projects.

With foundation walls, the slab on grade and force at the top of the wall is resisted by flooring. With retaining walls, the force at the top of the wall is not resisted.

The longevity of flood walls depends on how they were constructed, but most wood, gravel, and cement flood walls last 10 years. While aluminum flood walls may cost far more initially, they can be a good investment as they can last decades and will not be damaged by exposure to the elements.
