What to Consider When Choosing One of the Best Foundation Repair Companies

Homeowners don’t need to let the first sign of cracks or damage force them into an overpriced contract with an underqualified company. Instead, homeowners will want to first take a deep breath and then keep the following considerations in mind when comparing companies.

Service Area and Scheduling

Every foundation repair company and contractor will have a service area in which they work. Occasionally, these companies will carry licenses for specific areas like counties, states, or even regions, which may include several states. It’s important that homeowners find several companies that work in the area where they live to ensure they’re comparing apples to apples in terms of pricing and availability.

Also, once a homeowner starts the shopping process, they will want to consider scheduling. While it may not be an emergency, the sooner the homeowner can get the company on-site to evaluate the repair and provide a quote, the sooner they can make a decision. Some companies even offer online scheduling rather than scheduling over the phone, and that can make a difference for some busy folks.

Evaluation Process

Most companies will want to evaluate the home’s foundation and its condition before providing any sort of quote or estimate. And while this might seem like an inconvenience for the homeowner, it’s actually a vital part of the process of making an informed decision.

During the evaluation process, the contractor will look for what might be causing the issue as well as the repairs they believe to be necessary. If the homeowner goes through this process a handful of times with different contractors, they will likely have a solid understanding of what is causing the actual issue and what really needs to be done to repair it.

Homeowners will want to make sure the evaluation is free. Most companies are glad to come to the home and evaluate the issue without charging the customer in the hope of winning the job, so customers won’t want to pay for something that many other companies are willing to provide for free.

Type of Repair Needed

Every home is different, and every case of foundation damage is unique. What this means is that the same type of issue at two homes may require entirely different solutions. And the type of repair needed (or suggested) will determine quite a bit about how much the repair will cost.

Several types of repairs may be necessary, including:

  • Patches and small crack repairs: A quick and simple cosmetic repair for small cracks.
  • Slab jacking: The process of drilling holes and injecting polyurethane or a similar substance to lift the sinking slab.
  • Piling: Drilling deep under the foundation and installing steel or pouring concrete footings to stabilize the foundation.

Homeowners will want to note that some foundation repair companies specialize in certain repair techniques and products. They’ll also want to remember that there may be more than one way to repair a foundation, so it’s important not to get attached to one particular repair method over another.

Additional Services

Foundation damage doesn’t just happen. It’s typically the result of groundwater damage, erosion, or high moisture levels within the basement, crawl space, or slab. Some foundation repair companies can offer additional services that will help make the problem a thing of the past.

Homeowners can look for services such as excavation and drainage installation, waterproofing, slab leveling, mold control, and sinkhole repair. These extra services will cost more, but they can help solve the issue permanently, costing less in the long run than repairing the foundation in another few years when the issue rears its ugly head once more.

Contractor Licensing and Insurance

Some states may require foundation repair companies to carry specific licenses, such as a general contractor’s license or a business license. Hiring a company that does not hold a license may be illegal in some cases, so it’s important that homeowners know the legal obligations for contractors in their area.

Regardless of licensing, homeowners will want to ask for proof of general liability insurance. Doing so reassures them that, should something go wrong at the hands of the contractor, their home and bank account are both safe. If a contractor won’t provide a copy of their general liability insurance, it’s either because they don’t have it or their insurance doesn’t cover that type of work. In that case, it may be best for the homeowner to cross that contractor off their list and move on to the next one.

Warranty and Customer Support

Finally, it’s important to note that the best foundation repair companies typically offer warranties on their work. Should there be an issue with the repair down the road, the top companies will honor this warranty and fix the problem again. This can give the customer some peace of mind but also give the contractor more incentive to do the job right the first time.

Along with warranties, quality customer support also matters. If the customer can get hold of someone at the company easily, get answers to their questions promptly, and get a complete explanation of the evaluation and repair process, chances are the company has good customer support and service.

Our Top Picks

It may seem like there’s a lot for homeowners to consider when choosing the best foundation repair companies. To help make the decision easier, the following guide aims to simplify the shopping process a bit, highlighting some of our top picks for the job.

How We Chose the Best Foundation Repair Companies

When we put together a list of the best foundation repair companies, our goal was to offer more insight and viable options than a simple “building foundation repair near me” search would reveal.

To meet this goal, we performed extensive research on all the services and features we found to be important.

Before You Hire One of the Best Foundation Repair Companies

While foundation problems can be very concerning, there are some issues that don’t necessarily require repair. For example, small cracks and their repairs may not require a foundation repair company. In many cases, a simple concrete patch or sealant product will solve the issue, and the foundation will last for years and years before another issue pops up. However, homeowners who are unsure how serious their cracks are will want to consult a professional as a safety precaution.

Foundation cracks may bring to light other issues with the foundation or basement. Depending on those issues, customers may need to consider hiring one of the best basement waterproofing companies, best mold removal companies, or best water damage restoration services. Some foundation repair companies may also offer these services.

It’s also important for homeowners to know that their insurance policy doesn’t necessarily cover foundation repairs. The cost for repairs for “wear and tear” damage from foundations settling must come out of the homeowner’s pocket. However, events that cause damage that are named within the homeowners insurance policy may be covered, so it’s important for homeowners to check their policies.

Cost of Hiring One of the Best Foundation Repair Companies

In general, foundation repairs cost between roughly $2,010 and $7,717, with a national average of around $4,714. The damage and type of repair required will determine how much the job will cost.

For example, large jobs requiring the installation of piers or structural steel can far exceed $10,000. These projects typically require heavy equipment, several days on-site, a structural engineer, and inspections. However, small patches on superficial cracks or deterioration can cost $500 or less to repair. In general, it’s a good idea for homeowners to get quotes from several reputable foundation repair companies before signing a repair contract.

The Advantages of Using One of the Best Foundation Repair Companies

The best foundation repair companies offer free foundation inspections that allow them to put together an accurate quote while also educating the customer on the issue at hand. Technicians will arrive on-site (or via virtual inspection), look at the damage, attempt to diagnose the cause, and give the homeowner a report on the findings. This gives the homeowner a baseline to work from when comparing quotes.

Foundation repairs are not cheap, and homeowners generally don’t want to have to spend money repairing the same foundation issue more than once. The best foundation repair companies offer warranties that give homeowners some peace of mind if the issue should reoccur.

The best foundation repair companies have seen many different types of foundation damage and issues and are experienced with fixing them. They’ll know where the damage started, how to stop it, and how to repair the problem. Contractors who don’t specialize in foundation repair might not have the experience to make those calls, which could mean further frustration down the road.

  • Top-tier companies offer free inspections and reports.
  • Going with a top-rated foundation repair company may mean a better warranty.
  • Experienced foundation repair companies have the expertise to address a variety of issues.


That may be a lot of information on the best foundation repair companies, but there might still be some lingering questions. The following are some of the most common questions about foundation repair services, so homeowners will want to check below for an answer to their questions.

Q. What are the best methods of foundation repair?

There are a lot of different methods to repair foundations, and the best method depends on the cause of the issue.

Q. How much does foundation repair cost?

It depends on the damage, but the range is between roughly $2,010 and $7,717, typically. The national average is around $4,714.

Q. Is foundation repair covered by insurance?

It depends on how the damage occurred. Damage from age and wear and tear won’t be covered, but damage from earthquakes or floods might be, depending on if the homeowner has additional policies for these events.

Q. Are foundation repairs worth the cost?

In most cases, yes. The home’s entire structure sits on the foundation, so the damage could affect the rest of the home. However, homeowners will want to get and compare multiple quotes before settling on a contractor.

Q. How long does foundation repair take?

Foundation repairs can take just a few days or several weeks to complete, depending on the damage, cause, and solution.

Q. How do I know if a foundation repair company is reputable?

There are a few ways for a customer to judge a company’s reputation. First, they can take a look at how long the company has been in business.

Also, customers can check out the companies’ warranties, references, insurance coverage, and licenses to ensure everything is on the up and up.
