"First class all the way! Professional, highly competent and fair. Will recommend John to anyone I know. I had a well leak and a prior firm came out and gave me an outrageous quote for a solution that would not have addressed the problem. I reached out to Conex to do excavation to better assess the problem and not only did he get out quickly to do the excavation he was also able to diagnose and fix the issue at a lower cost. "

"I am writing to formally express my deep dissatisfaction with the recent retaining wall replacement project completed by John Krause Construction (JKC) at my property. After reading positive reviews and receiving an estimate that, although over my budget, seemed reasonable for the work involved, I made the decision to hire JKC. Unfortunately, this has proven to be a significant mistake, and I am left extremely disappointed with both the quality of work and the overall experience. Here are the main issues I encountered: 1. Unprofessional Behavior: The crew exhibited unacceptable behavior while working on my property. Not only did I witness them disposing of bodily fluids on-site, but they were also disrespectful and dismissive. when I raised concerns no response was received. I now smell urine when entering and exiting my garage. 2. Unresponsive Ownership: I have attempted to reach out to the owner multiple times to address these concerns and resolve the issues, but my messages have been met with silence. This lack of communication is incredibly frustrating and has only added to my disappointment. The owner refused to speak on the phone since the owner was made aware of the call being recorded. 3. Property Damage: During the construction process, my property was left damaged in multiple areas. This included e.g., landscaping destruction, equipment damage. Personal crew members vehicles being driven through my yard leaving deep tire marks damage. 4. Subpar Quality of Work: Despite the high cost of the project, the final result does not meet the standards outlined in the estimate or contract. No proper grading was completed. Every time it rains pools of water sits in front and behind the wall. The response received was. “we have passed all inspections.  There will be some water pooling while it is settling still. Plus the fact of the hard rain today, it will happen.” The wall has been completed for 2 months. Given the extensive problems, stress and anxiety I have faced. I do not recommend John Krause Construction."

FAQs for concrete foundation installation projects in Rockville, MD

A concrete footer is a relatively shallow column of concrete that sits below your foundation walls. Footers spread wider than the foundation, so they can support a higher amount of weight in critical spots, such as below walls. The exact dimensions of footers depend on the home, so larger structures need a larger footing.

To calculate footing size, you need to know the minimum width and depth for houses in your region. Multiplying the width by the linear footprint of the structure will give you the size in linear feet.

To convert linear feet into square feet, you can divide the width by 12. For example, an 18-inch footer is 1.5 square feet per linear foot. Multiply this number by the total in linear feet to get the answer in square feet.

Installing a pier and beam foundation costs $5 per square foot, or $8,000 to $15,000. This style is standard in homes built before the 1960s or those in flood-prone areas.

Concrete weight support ranges from 1,500 to 6,500 pounds per square inch, and footings need at least 3,500 to 4,500 pounds per square inch. Remember that your soil type, climate, and materials used will significantly affect how much weight your footings can hold, especially in certain areas.

It costs between $1,600 and $3,200 to pour a 20-by-20-foot concrete slab. These estimates are based on an average cost to pour a concrete slab of $4 to $8 per square foot. Be sure to discuss the specifics with a pro—they’ll give you an estimate of how much you can expect.

The cost to raise a house is between $3,200 and $10,000. This range refers to a form of repair that involves lifting the entire house to potentially remove the old foundation and build a new one or add to an existing one.
