How To Choose a Foundation Repair Company

Hiring a qualified foundation repair business ensures you have someone who will inspect the damage thoroughly and make appropriate fixes. It's important to conduct research beforehand, focusing on the factors listed here.

Experience

Look for a well-established local company with many years, ideally decades, of experience successfully handling all kinds of foundation repairs. These companies have specialized expertise using the latest methods and materials. Ask how long a company has served homes in your area.

Reputation

Spend time researching online reviews, browsing the Better Business Bureau, and asking for local references. This will help confirm that the company consistently delivers quality work and professionalism. Take note of any complaints describing poor service or faulty repairs.

Licensing and Insurance

It's important to select a provider that has valid credentials, bonding, and insurance for liability and workers' compensation. Washington does not have state-level licensing requirements for contractors, but they must register with the Washington State Department of Labor & Industries. Registration requires contractors to be bonded and insured. Be sure to check with your city, county, or municipal government to learn about any additional local requirements. Contractors may have to meet additional requirements to do certain work with concrete.

Warranties

Look for a provider that offers lengthy transferable warranties for a minimum of a decade, preferably lifetime guarantees, to back its repair work. This demonstrates faith that its services are top-quality and safeguards you if issues arise in the future.

Questions To Ask Foundation Repair Companies

To compare foundation repair providers, you should ask specific questions such as:

  • What type of guarantees are provided? Reputable companies will offer warranties of at least 10 years on labor and materials.
  • What do you see as the likely cause of my issues based on your inspection? Look for clear explanations and solutions in the answer. Companies that provide vague answers may be trying to bill you for unnecessary work.
  • What repairs would you recommend for this situation, and why? Your contractor may provide options such as steel piers, wall anchors, and carbon fiber. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • Can you provide a complete written cost estimate and project scope? Getting quotes in writing helps protect you from unexpected expenses.
  • How long will the repairs realistically take to complete? Look for providers that provide reasonable estimates.
  • What financing options do you offer? Many providers offer payment plans for larger foundation projects.

Carefully evaluating foundation repair companies helps homeowners identify the ideal match for their needs. A provider that can answer the questions above is likely one that provides long-lasting, durable repairs. Promptly fixing foundation problems helps prevent further structural damage.

Frequently Asked Questions About Foundation Repair in DuPont, WA

If your foundation is in need of repair, it may manifest in a number of ways. Outside, you may notice a crumbling or cracking foundation or cracks in your driveway. Your ground level or basement might have cracked or uneven floors. You might notice windows and doors that are sticking in their frames, or that the frames are skewed. You might also notice bowing, cracking, or buckling walls.

On average, DuPont homeowners spend around $2,862 on foundation repair. The total cost of foundation repair will vary greatly depending on several factors. Things like the size of your home, the type of repair needed, and the extent of the damage will all play a part. The easiest way to learn how much a job could cost is to speak with a local foundation repair expert and schedule a free inspection and estimate.

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

Crack repair and leak repair are what they sound like: your foundation contractor will perform an inspection and complete any repairs necessary to remedy cracks or leaks. The price will vary based on the size and cause of the problem.

Underpinning, also called piering or leveling, is the process of leveling your foundation by underpinning it with large concrete piers. The cost will depend on how many piers are used. The price of stabilization is also variable. This process reinforces bowing walls with steel or carbon fiber strips, and the cost will depend on what material is used and how many strips are used.

Finally, waterproofing is an overarching term for a category of repairs designed to stop water from getting into your foundation or basement. This can include exterior waterproofing, interior waterproofing, or both, and the price can vary greatly. We recommend contacting a waterproofing specialist if you think your foundation needs waterproofing.

If you're constructing a new home, have a soil report completed. This report contains information regarding how well your soil can support a foundation, and can give you a heads-up about potential future problems. If your concerns are about an existing house, a few hundred dollars will cover an inspection and report by a structural engineer. They can alert you to any issues that need attention, and give you advice on how to avoid future problems.

Also ensure that the moisture around your foundation is appropriate. As DuPont sees more rain than many other places, keep an eye on your gutters and landscaping to make sure too much water isn't getting into your soil or foundation. You should also stay vigilant for leaky pipes or gutters, so you can get them repaired promptly.

Your foundation repair expert should be the one obtaining the permits. You can ask the company to provide a detailed explanation of the steps in its process and to see the paperwork and permits it has acquired to make sure everything is properly authorized per DuPont regulations.

You should talk to your foundation repair technician about your concerns before committing to any project. Most of the time, yes, you and your family will be able to remain at home while foundation repairs are underway.

Small hairline cracks might seem easy to take care of yourself, but in general, you should consult a professional before beginning any foundation maintenance. While you may not want to pay someone for work you feel like you can handle yourself, foundation repair mistakes can be even more costly in the future.
