Foundation Repair Cost in Porterville

Foundation repairs are not one-size-fits-all. There are different ways foundations can be repaired, depending on the current problems and the underlying issue.

Waterproofing can do a lot to protect your house from future problems, but it can cost a good deal. Sometimes, there are cheap and simple solutions, such as rerouting your house's gutter system. Your home may need interior waterproofing, which involves things like the use of sump pumps and the installation of drains. Exterior waterproofing is often the most expensive, as it can involve redoing your landscaping or applying rubber coating to your entire foundation. Exterior waterproofing can cost over $10,000 depending on the extent of the repairs needed. You should try to talk to a waterproofing contractor in Porterville if you think any of these services will be needed, as not every foundation repair company is fully equipped to do foundation or basement waterproofing.

Other types of foundation repair include:

  • Piering / Underpinning / Leveling: These terms generally refer to the same process: adding piers (concrete pillars) as support under your foundation. This major repair could run in the thousands of dollars per pier, but undergoing this process can go a long way towards preventing future problems.
  • Crack Repair: Fixing a crack in your foundation usually costs hundreds of dollars. Both the cost and method used to fill it will depend on the size of the crack(s). Smaller cracks can be filled with epoxy or polyurethane foam and cost less, while larger cracks may require concrete fill and cost more.
  • Stabilization: The cost of stabilization will depend on if carbon fiber or steel is used in the process. Your foundation repair company will add metal strips inside your walls to reinforce them and fix bowing. The strips may run several hundred dollars apiece.
  • Leak Repair: Leaks are usually a sign of a larger issue, and your Porterville foundation repair professional could recommend waterproofing along with fixing the leak. The cost of this repair will be highly variable based on exactly what is needed.

Signs Your Foundation is in Need of Repair

It can be hard to tell on your own if your foundation is in need of repairs. There are, however, some signs you may notice that indicate a need for professional help. You should get in touch with a local Porterville foundation repair company for an inspection if you notice:

  • Cracked driveways
  • Visibly damaged or crumbling foundation
  • Cracks in foundation walls or flooring
  • Water in your basement
  • Uneven basement floors
  • Shifted, skewed, or tight doorframes or window frames Walls that lean inwards at the top
Indicators that your Porterville home may require foundation or basement waterproofing are:
  • Visible water in your basement
  • White powder, spots, or other signs of fungus
  • Presence of mold or mildew
  • Changes in floor height or newly uneven floors
  • Damp or musty-smelling basement Bowing or buckling walls

Choosing a Porterville Foundation Repair Company

When you're looking to hire a foundation repair company in Porterville, there are some things to keep in mind:

  • Licensing and Insurance: Your Porterville foundation repair company should be able to provide proof of general liability insurance before you sign a contract. You may also want to verify if the company meets the general contractor licensing requirements for California.
  • Inspection and Estimate Process: You should ask for a free inspection and estimate from your foundation repair company. After the inspection, you should better know what repairs are necessary and how much you can anticipate paying.
  • Cost: When looking at quoted prices, be wary of companies who seem to offer extremely low or extremely high quotes. You should also look out for things like travel fees if the company headquarters is far from your home. It's recommended that you get quotes from multiple companies to compare.
  • Partnerships With Structural Engineers: Many foundation repair companies contract with a structural engineer. The structural engineer will (for a fee) verify the results of the inspection. They will confirm that the suggested repairs are both necessary and appropriate. If your foundation repair company does not work with a structural engineer, you can hire one yourself.
  • Warranties: A trustworthy foundation repair company should offer a warranty for their work. The details, including things like exactly what is covered and for how long, may vary depending on the company and even based on the weather in your part of California.

Your foundation is a very important component of your home, and it can affect many other things. For this reason, you want only one of the top foundation repair experts in Porterville to work on it. By using our list, you'll stay in safe and reliable hands.

FAQ's for Foundation Repair in Porterville

What are some things I can do to protect my home's foundation?

If you're planning on building a new home or an extension on your current home, you can get a soil report before beginning construction. This will tell you whether the soil in a specific location can support a structure without sinking or shifting. For an existing home, you can pay a structural engineer (usually a few hundred dollars) to inspect your foundation and let you know if there are any signs of deterioration or damage. And of course, if you see any problems yourself, contact one of your local foundation repair experts in Porterville to see what can be done about it.

If the weather in Porterville gets particularly hot and dry, you might need to water your foundation. This helps prevent the surrounding soil from drying out, crumbling, and increasing the risk of foundation shift. (You may need to do this more often in Porterville, due to the lack of frequent rain in the area.) However, make sure to avoid overwatering your foundation, as having excess moisture can cause just as many issues as not having enough.

Will I be able to remain in my Porterville home while foundation repairs are going on?

Most of the time, the answer is yes. Throughout most foundation repairs you'll be allowed to stay at home. Be sure to check with your Porterville foundation repair experts so that you're aware of all details before you sign a contract.

Can I put off a foundation repair project?

It is best not to put off foundation repairs. Even problems that seem minor can be indicative of a bigger issue, and your foundation is too important to neglect.

How long does it take to finish various foundation repair projects?

The amount of time a foundation repair takes will vary greatly depending on the kind of repair that is needed and the size of your home. Most repairs take anywhere from one to several weeks. Talk to your Porterville foundation repair professional for a more specific timeline for your project.
