How To Choose a Foundation Repair Company

Conduct research before beginning your foundation repair project, so you can find the most qualified foundation repair company. Here are the main factors we recommend considering.

Experience

Look for a local foundation repair company with significant experience fixing all foundation types. It should have specialized knowledge of the latest repair methods and materials. Ask how long a provider has served your area.

Reputation

Spend time reading through online reviews, browsing the Better Business Bureau, and requesting local references. This will help confirm that a provider consistently delivers good workmanship and great customer service. Take note of complaints describing poor service or faulty repairs.

Licensing and Insurance

Choose a company that has valid licenses, bonds, and insurance policies for liability and workers' compensation. Contractor licensing in Oregon is handled by the Oregon Construction Contractors Board. Contractors must pass an exam, and must be bonded and insured. There may be additional requirements for contractors to do certain work with concrete.

Warranties

Choose a company that offers long transferable warranties of at least 10 years, ideally up to lifetime guarantees, to fully back their foundation repairs. This demonstrates confidence in the quality of their work and offers protection in case of future issues.

Questions To Ask Foundation Repair Companies

As you evaluate potential foundation repair companies, make sure to ask specific questions such as:

  • What foundation flaws did you identify 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 attempting to bill you for extra work.
  • Can you provide a cost estimate and project scope in writing? Make sure to get quotes in writing to protect yourself from unexpected expenses.
  • What repairs do you recommend for my situation, and why? Your contractor may consider options such as wall anchors, carbon fiber, and steel piers. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • What options do you have for financing? Providers often offer payment plans for larger foundation repairs.
  • What warranties do you provide? Reliable companies generally provide labor and materials warranties of at least 10 years.
  • Realistically, how long will repairs take to complete? Look for companies that provide reasonable estimates.

Carefully assessing foundation repair companies helps homeowners locate the best fit for their needs. A company that can answer the above questions likely completes durable, high-quality repairs. Fixing foundation problems quickly reduces the risk of future structural damage.

Frequently Asked Questions About Foundation Repair in Cornelius, OR

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

On average, Cornelius homeowners spend around $2,375 on foundation repair. The total cost of foundation repair depends on a number of factors. Things like the type of repair needed, the size of your home, and the extent of the damage will all play a part. The easiest way to determine how much a job is going to cost is to speak with a local foundation repair company and schedule a free inspection and estimate.

Types of foundation repair include leak repair, crack repair, stabilization, underpinning, and waterproofing.

Leak repair and crack repair involve a technician coming to your home, completing an inspection, and using various measures to fix leaks or cracks. The amount you spend can vary greatly depending on the size and cause of the issue.

Stabilization reinforces bowing walls by inserting carbon fiber or steel strips. The amount you spend will depend on the material chosen and how many strips are needed. The cost of underpinning also varies. This process, also called leveling or piering, involves leveling your foundation by underpinning it with concrete piers; the cost will be based on how many piers are needed.

If you're looking to waterproof your foundation or basement, we recommend talking to a waterproofing specialist. This process might include outdoor waterproofing, indoor waterproofing, or both.

When building a new home, have a soil report completed. This report contains information regarding how well your soil can support a foundation, and can offer you a heads-up about any potential future problems. If your concerns are about an existing house, for a few hundred dollars, you can get an inspection and report by a structural engineer. They can point you to any issues that could use some attention, and advise you on how to avoid future problems.

It's also important that the moisture around your foundation is appropriate. As Cornelius 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. Also, be on the lookout for leaky pipes or gutters and repair them quickly.

Your foundation repair expert should be the one to get the permits. You can request that the company provide a detailed explanation of the steps in its process and to see the paperwork and permits it has acquired to confirm everything is properly authorized per Cornelius regulations.

When you need foundation waterproofing, you'll notice signs like basement flooding, hairline cracks, white powder or spots on your walls, discoloration or odors, uneven floors, or signs of fungus, mildew, or mold.

You can opt for interior or exterior waterproofing. Interior waterproofing is generally less expensive, and involves solutions such as the use of sealants or the installation of sump pumps or drains. Exterior waterproofing tends to be more expensive but more effective. This process can involve things like external drains, landscaping changes, or physical barriers to keep water out of basements and crawl spaces.

We caution against putting off a foundation repair project. Minor issues may have an underlying cause that could potentially result in future problems, and it's best to treat the root of the issue as fast as possible. A small and moderately costly problem now could turn into a large and very expensive one in the future if the signs are ignored.
