"Professional, excellent workmanship, responsive, punctual, pride for work. We interviewed five concrete companies before settling on Garay Concrete. From start to finish Adrian and his crew were professional, punctual and responsive to our questions and any concerns. They did an enlarged step and walk area and new driveway/parking space to the front entry. Everything was started and completed as promised in time and quality. It was clear that Adrian and his crew take great pride in their work. Neighbors have raved about the work they did and we very much agree."

FAQs for concrete foundation installation projects in Longmont, CO

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.
