"We had our patio done since it was sinking. It came out beautiful but after a day it sunk about a 1/4 inch. They gave us a updated warranty for a year that if it sinks more than an inch they will come out and fix it. The quote came back less than their competitor."

"I have had two issues since they installed the new sump pump and irrigation. Issue number one was water still getting passed the new concrete. The other issue is that the new concrete was not level at all which has caused issues with the new flooring I installed. However, their customer service is top notch and will work hard to take care of you."

"Great start, the work was halted for a week due to unforeseen damage to the water pipes. This was not the Concrete Champs Co.'s fault, previous owners of our home had redone the water pipes not to code and the water pipe was right below the driveway, rather that 2 feet. After the water pipe was repaired and placed further down per code, the driveway construction was resumed.. No further issues and we know have a high quality driveway that was built correctly, with layers of gravel, re-bar reinforcement, and sealed after completion. It looks great and is built to last."

"If you need concrete work done this is the company to pick. Their price was fair, they do high quality work and are great to work with. Nelson responded very quickly to our request and had some good ideas for what needed to be done. They finished our driveway ahead of time and we get lots of complements on it!!!"

Concrete Mudjacking FAQs, answered by experts

Many contractors offer warranties for their work. Confirm terms before starting the project.

Mudjacking can be an expensive foundation repair process, but in many cases, it’s well worth the investment. This is especially true if you’re lifting a portion of sunken foundation slab back into place. In that case, mudjacking can help avoid major structural damage and even home collapse by restoring the integrity of your structure with minimally invasive procedures. Mudjacking a concrete patio, walkway, or sidewalk can be worthwhile because it removes tripping hazards and makes your outdoor area more aesthetically appealing.

Most states and municipalities don’t require concrete mudjacking companies to carry a specific license, but they usually need to have a general contractor’s license, and they should be fully insured. The only exception is if the mudjacking company provides foundation repairs as well, or if it offers mudjacking for home foundations. In that case, they will typically need a foundation repair contractor’s license. You can check state requirements and then use Angi’s license lookup tool to confirm that a company is properly licensed to provide mudjacking services in your area.

Common issues with concrete that may require professional repair or resurfacing include cracks, spalling, uneven surfaces, and weather damage.

Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.
