How To Choose a Foundation Repair Company

Working with a qualified foundation repair provider is important for properly evaluating the damage and making the right repairs. We recommend focusing on these main factors.

Experience

Look for a well-established local company with a long track record of experience successfully handling all types of foundation repairs. These providers have specialized expertise with the latest methods and materials. Ask how long a company has been serving your area.

Reputation

Researching online reviews, checking the Better Business Bureau, and asking for local references helps you confirm that the provider consistently delivers good workmanship and a great customer experience. Pay attention if you see numerous complaints about shoddy repairs or poor service.

Licensing and Insurance

Only hire companies that are properly licensed, bonded, and have both liability and workers compensation insurance. Texas does not have state-level licensing requirements for general contractors, although all contractors are required to hold a valid state business license. Your city, county, or municipal government might have local licensing requirements, so be sure to verify this information before signing a contract. Contractors may have to meet additional requirements to do certain work with concrete.

Warranties

Pick a provider that offers warranties of 10+ years that you can transfer to a new owner if you sell and, if possible, lifetime guarantees to fully back its services. This displays faith that their repairs will be high-quality and long-lasting and provides protection should problems come up later.

Questions To Ask Foundation Repair Companies

When comparing potential foundation repair companies, be sure to ask detailed questions such as:

  • Realistically, how long will the repairs take to complete? Look for providers that provide reasonable estimates.
  • What foundation defects did you find during inspection that may be causing the issue? The response should have easy-to-understand explanations and solutions. If a provider offers an unclear answer, it may be trying to bill you for unnecessary work.
  • What repair method would you recommend for my specific situation and why? Your provider may consider options such as wall anchors, steel piers, and carbon fiber. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • Can you provide a project scope and cost estimate in writing? Be sure to get quotes in writing to shield yourself from unexpected expenses.
  • What financing options do you have? Many providers offer payment plans for larger foundation projects.
  • What warranties do you offer? Reputable providers typically provide labor and materials warranties for at least 10 years.

Thoroughly evaluating foundation repair companies will help you identify the right one for you. Providers that can thoroughly answer these questions will likely offer high-quality, durable repairs. Promptly addressing foundation issues helps avoid future structural damage.

Frequently Asked Questions About Foundation Repair in San Marcos, TX

If your foundation needs repairs, you may notice a number of symptoms. Outside your home, you might see a crumbling or cracking foundation or a cracked driveway. Your ground level may have uneven or cracked floors. You might notice windows and doors sticking in their frames, or frames that are skewed. You might also notice cracking, bowing, or buckling walls.

On average, San Marcos homeowners pay around $2,037 for foundation repair, although the cost will vary widely depending on several factors. The best way to get an estimate for the cost of a specific project is to get quotes from a few local foundation repair companies. Your total cost will be affected by things like the size of your house and type of repair(s) needed.

The main types of foundation repair are crack repair, leak repair, underpinning, stabilization, and waterproofing.

Crack repair and leak repair are exactly as they sound: your foundation contractor will perform an inspection and take necessary measures to remedy cracks or leaks. Costs will depend on the size and cause of the issue.

Underpinning, also called piering or leveling, is the process of leveling your foundation by underpinning it with large concrete piers. The amount you can expect to spend depends on how many piers are required. The price of stabilization varies similarly. This process involves fixing bowing walls by reinforcing them with carbon fiber or steel strips. The total cost will depend on the material chosen and how many strips are used.

Lastly, waterproofing is an overarching term for a number of jobs designed to stop water from getting into your foundation. This can involve interior waterproofing, exterior waterproofing, or both, and costs can vary widely. We recommend contacting a waterproofing specialist if you're planning to waterproof your foundation.

To protect your foundation, you should make sure that it gets the right amount of moisture, especially in hot weather. Avoid letting the soil around your San Marcos house become too wet or too dry – make changes to your gutter system to route water away, or water your foundation if it starts to get too dry. Additionally, be sure to quickly identify and repair any leaking gutters or pipes.

If you have any concerns about your foundation, you can reach out to a structural engineer for an evaluation. This will cost a few hundred dollars, but the engineer's consultation can net you a list of potential concerns as well as additional steps to further protect your foundation. Lastly, if you're building a new home, ensure to have a soil report done. This report provides information about how well the soil on your property can support a foundation and highlights any potential future problems.

Foundation repair usually requires a permit, but getting one shouldn't be your responsibility. Your foundation repair professional should put together the permit and all other documents required in San Marcos, and should be able to explain the process and/or provide the documents before starting work.

In general, foundation repairs will have a positive effect on the value of your home. In some cases, you may be able to consider foundation repair a capital improvement, which can sometimes help you qualify for tax breaks. Generally, a capital improvement is defined as one that will add to a home's overall value, prolong its life, or adapt it to new uses. Talk to your Texas tax professional for more information.

The amount of time foundation repairs will take varies greatly based on the type of repair that is needed and the size of your home. Most repairs will take anywhere from one to several weeks. Consult your San Marcos foundation repair expert for a more specific timeline for your project.
