Your Foundation Contractors questions, answered

Answers to commonly asked questions from the experts on HomeGuide.

How much does it cost to install a foundation?

The cost to install a foundation depends on the type of foundation installed. The most common types of foundations are concrete slabs, pier and beam, crawl space, and basement foundations.

  • A concrete slab foundation costs about $6 to $12 per square foot for a single, poured concrete slab that rests on the ground.
  • A pier and beam foundation costs $8 to $15 per square foot and is made up of concrete or metal piers supported by beams. These foundations are common in areas with sandy or unstable soil.
  • A crawl space foundation costs $15 to $18 per square foot for the elevated foundation with enough space to crawl through. These foundations are common in warmer climates where the frost line is not deep or on sloping lots since they don't require as much excavation as other foundations.
  • A basement foundation is the most expensive at $35 to $50 per square foot. This foundation provides the most space and flexibility. A finished basement foundation can double the living space of a home.

Do you install septic before a foundation?

Yes, you generally install the septic system before pouring the foundation for a new home. The leach field and septic tank need to be located in a specific area of the property and this is easier to do before the foundation is in place. Installing septic first also allows you to have water available on-site during construction.

How much does it cost to fill in a crawl space?

Filling in a crawl space or crawl space encapsulation costs $3,000 to $8,000. Prices include basic cleaning, minor repairs, mold removal, and installing a vapor barrier, a sump pump, new insulation, and a dehumidifier. The total project cost depends on the condition and size of your crawl space, the type of insulation you choose, the thickness of the vapor barrier, and the pump and dehumidifier installed.

Crawl space encapsulation prevents excess moisture, mold growth, radon gas poisoning, and pest infestation. The process also helps alleviate allergens and pollutants to improve air quality. Another benefit of crawl space encapsulation is better insulation that can reduce energy bills by up to 20%.

How long does a poured concrete foundation last?

A poured concrete foundation can last for 80-100 years or more if it is properly constructed and well-maintained. However, a number of factors can affect the lifespan of a concrete foundation, including the quality of the concrete mix and the workmanship, the climate and soil conditions, and the amount of weight the foundation is supporting.

Some of the most common reasons a foundation fails include:

  • Poor drainage
  • Frost heave
  • Tree root invasion
  • Earthquakes and other seismic activity

How deep does a concrete foundation need to be?

Generally, a concrete foundation needs to be at least 12 inches deep to ensure the foundation is below the frost line and can support the weight of the structure. In some cases, a deeper foundation is required. If you are building in an area with a high frost line, poor soil quality, or building a very heavy structure, you may need to dig deeper.

A qualified structural engineer can help determine the appropriate depth for your concrete foundation.

What questions should I ask a foundation contractor?

Here are some questions you can ask a foundation contractor to ensure you are making the best choice for your project:

  • Is your company licensed, bonded, and insured for foundations?
  • How long have you been pouring foundations in my area?
  • What experience do you have installing my preferred foundation type?
  • What does your estimate include?
  • How long will the foundation take to install?
  • Do you have past clients I can contact or a current job site I can visit?
  • Do you offer a written estimate, contract, and timeline for the job?
  • What happens if the foundation is delayed due to weather or other unforeseen circumstances?

How do I choose a foundation contractor?

Selecting and pouring a foundation is one of the most important steps in building your new home. Choose the best foundation contractor by following these steps:

  • Get at least 3 estimates with the same foundation type to compare costs.
  • Confirm the contractor's experience with your preferred type of foundation.
  • Make sure the contractor is licensed, bonded, and insured, with 5 years of experience.
  • Look for foundation contractors with good reviews on HomeGuide and Google.
  • Ask for references from past clients and follow up to get their opinion on the work quality.
  • Confirm if the estimate includes labor, materials, and equipment costs.
  • Ask for a contract in writing that includes the costs, timeline, and warranty information.
