The 5 Best Foundation Repair Contractors in Phoenix

How We Picked 

How we picked


The company should have the license to perform the trade and its employees should be trained and certified in their respective fields. Their years in business are also telling of their reputation and experience.


Through clients’ experiences and past projects, we assessed the quality of the repair and methods of foundation stabilization. Each scenario is unique so they should have the knowledge and equipment to resolve them.

Project Management

We evaluated their efficiency in meeting deadlines within a set timeline, as well as their planning and execution. This includes the manner of communication with other trades and clients.

Payment Terms

The costs should be paramount to the outcome of the project through a well-written contract. This should detail the schedule of payments and warranty, which guarantees that the job will be done right the first time.

  • Offers custom financing plans with 0% interest
  • Responds quickly to inquiries and job orders
  • Rated A+ and BBB-accredited

  • Young foundation repair contractor of only 7 years
  • May decline projects that are not within their capabilities

Dalinghaus Construction, Inc. is a California-based contractor for foundation and other concrete repairs, but also serves all of Arizona. Their passion for the trade is apparent with their wealth of knowledge and a track record of over 2,200 satisfied clients.

The company is headed by brothers Brian and Brad Dalinghaus, who have decades of experience in the construction industry. They started with home renovations in 2011 but rapidly expanded to foundation repairs four years later.

They’re one of the youngest companies in foundation repair in the valley, which is impressive considering their consistent growth. 

They owe this to a network of loyal clients and other field professionals like architects and engineers who continuously refer them to others. It’s no wonder because of their superb workmanship and well-organized system of overseeing projects.

Another thing we like about them is their support for other local contractors. For jobs that are out of their scope, they’re ready to redirect clients to another reputable company that can efficiently handle the project.

Aside from foundation stabilization, they’re also well-versed in hillside repairs for those whose houses are built in sloping areas.

Prospects can avail of their free, no-obligation inspections and estimates if you’re not sure about needing any repairs yet. Their foreman and crew are more than inclined to offer helpful advice on how to proceed without any pressure, which we like.

All parts and labor also come with a 25-year warranty and a 0% interest financing plan with no hidden fees.

  • Offers free inspections for homeowners
  • Rated A+ and accredited by the BBB
  • Highly-trained technicians including structural and geotechnical engineers
  • Updated on the latest tech on foundation repairs
  • Offers a 12-month financing plan with zero interest
  • Support works products include a lifetime warranty


  • Doesn’t honor the warranty for some
  • Some reports of sales reps being unresponsive and hard to reach
  • Stringent cancellation policy

The Arizona Foundation Solutions LLC is a local business founded by Robert Brown in 2001. It’s worth mentioning that he has 30 years of experience in construction and is one of the few Certified Foundation Repair Specialists (CFRS) in Arizona. 

On the other hand, the company is certified by the International Concrete Repair Institute, Inc. (ICRI) and is an active member of Supportworks.

In simple terms, their technicians are all professionally trained and continue to learn about the best practices and latest advancements in foundation repair. Moreover, they use only cutting-edge and top-quality products in their projects.

Prospects can first avail of their free inspection through their online form, but later conduct a thorough inspection that involves soil borings and lab tests. We heard they’re informative and honest with the assessment, which we appreciate.

This is also probably why other construction professionals consult with them for advice. The consistency of service towards clients and other tradesmen is a quality to look out for and is a plus in our book.

Another thing we like is that they offer a variety of financing plans, including a 12-month scheme without interest. They also have a lifetime warranty on their products, which is generous.

However, some have reported that the contractor doesn’t honor the warranty when they encountered issues after the job completion. Foundation repair costs thousands of dollars, so we hope they would at least hold their end of the bargain.

To add, it seems their sales associates are hard to reach after signing a contract or paying a deposit. This was the case for a number of customers who have expressed their disappointment in the lack of response that even go on for months for some.

  • Punctual and flexible with scheduling
  • Meticulous and high-quality craftsmanship
  • ICRI-certified
  • Very responsive phone rep and techs
  • Transparent with fee structure


  • Relatively young company compared to others
  • Doesn’t offer financing services
  • No ready information on warranty terms

Gaje Contracting LLC is a local full-service concrete repair company that covers both structural and cosmetic repairs. In their experience, it’s all about the quality of their work more than the number of their finished projects.

This philosophy has worked well in their favor as far as we’ve seen, and most of their clients are happy about getting the job right the first time. As a small business, we like their can-do attitude with projects of all sizes, big or small.

To prove their dedication to a high standard of craftsmanship, they achieved an ICRI certification as leaders in their field. Among their offers are concrete slab leveling, stem wall repairs, and foundation stabilization.

According to clients, their team is responsive throughout the whole process and is always on the dot. One of the homeowners had to reschedule them a couple of times for personal reasons, and they were apparently flexible and understanding.

In addition, the techs spend time answering questions and giving honest assessments without the high-pressure sales and add-ons. This is something fairly common in this line of work, so we’re fans of their level of professionalism.

On another note, we wish they could also include financing in their future plans. It would also help if they had info on their products and warranty for reference.

Nevertheless, they’re firm within their cost estimates and are always on schedule. We recommend them for homeowners in need of urgent repairs since their turnaround times are one of the fastest we’ve seen around.

  • BBB-accredited and Rated A+
  • Innovates new system advancements
  • Responsive and conscientious towards clients
  • Offers custom financing plans 
  • 40+ years of industry experience


  • Few delays in turnover
  • No response after negotiating cost estimates for some

Ram Jack offers comprehensive foundation repair services across 50 locations nationwide. Over the course of 40 years, they’ve grown to become an industry leader in their trade and have served thousands of homes in the valley.

With years of experience, they actively develop and improve existing methods and systems while patenting their own. This is possible through their research and development division which consists of certified structural engineers. 

Furthermore, they pride themselves in using American-made and eco-friendly products that prevent toxic substances from seeping into the groundwater. All these come in a variety of solutions such as driven piles, helical piles, micropiles, and the whole nine.

As a result, they’re able to address a breadth of issues, even those that are seemingly more challenging. Clients are fans of their systematic approach from start to finish, and even reach out after completion.

Their expertise is apparent in their work, which is thoroughly done. We like that they also address problems they encounter along the way and even repair minor damages that were inadvertently caused by their construction.

Another thing we like is that they involve their clients in the processes to make sure they’re aware of the proceedings. During inspections, they leave no stone unturned and investigate the structure from top to bottom.

Foundation repairs don’t come cheap, but fortunately they offer flexible financing options and a Ram Jack Warranty Trust specifically for homeowners. 

On the other hand, there were a few cases with delays that were weeks beyond the promised deadline. Some have also slipped the cracks early on in terms of negotiating cost estimates, which resulted in declining their business.

Still, they’re apparently apologetic and reach out to clients with concerns and grievances, which counts for a lot.

  • Offers free assessments
  • Highly communicative and responsive
  • Fast repair and installation services
  • Affordable fees


  • Not a lot of proven work on foundation repair
  • Limited solutions in terms of piling systems

Arizona Foundation Works specializes in stabilization and settlement issues for both residential and commercial buildings. They’re based in Chandler but their services are available throughout the state.

The company is family-owned and -operated by husband and wife Rick and Mie Eakin since 2006. They pride themselves in offering innovative solutions for foundation repairs, crawl space encapsulation, and concrete lifting and leveling.

Among the technologies they use is the geotechnical polyurethane system, which is a foam-like substance that stabilizes soil and concrete slabs. This is typically a fast solution but may not address serious issues that affect the substructure of a home.

In terms of piling or piering systems, the options they offer are quite limited compared to other contractors. Because of this, they may not be equipped to handle larger-scale projects with extensive foundation damages, which is something to consider.

Other than that, we like that the owner Rick personally meets clients during inspections and generously provides sound advice for free. He’s also very communicative and doesn’t obligate homeowners to use his business.

Their products have a warranty attached to them, but you may have to contact them regarding the terms. Their services are also relatively on the cheaper end of the scale, but we still hoped for more details on their financing plans.

Still, we think they’re a great choice for foundation inspections and for smaller to mid-sized projects with quick turnaround times.
