"The nicest and hardest working construction crew and company Iâ ve ever dealt with. Extremely excellent customer service. Employees showed up several minutes earlier than expected every morning. The large crew always work together along with the boss doing a lot of grunt work himself. They laughed and really seem to enjoy doing their job together as a team. We could not be happier with the driveway that we have waited for for 10 years."

FAQs for concrete foundation installation projects in Sammamish, WA

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.
