Justin and Dustin were very professional and did a great job with a panel lift and filling cracks in the HOA's concrete cart path.

My Patio concrete slab had cracked in the 1995 earthquake and had gradually settled over the years. We wanted to tile the area but with the uneven slab (ranging from +1/4" to +7/8") we needed to get the slab leveled and stabilized. This was the first time that I had contemplated using a foam injection method for stabilization and leveling. Slabjack Geothechnical (Andrew) was professional, technically competent (I am an engineer) and exuded confidence (they have an impressive video display of a variety of successful projects) and most importantly - they have excellent reviews! Jamie came out and got the entire area (with it's multiple cracks) leveled! Kudos too to the owner Jerry, and Manager Ann, who were courteous, patient, and did not hustle me into making a hurried decision. Thank you to all of them.

We had our cement front porch sink over an inch and also had some of our driveway drop by 1/2"-3/4" in multiple places. We had people tripping on these areas. Some large cracks were also appearing across the driveway and the bottom of our porch steps. We called SlabJack Geotechnical come and evaluate and give a free estimate. Their website had great videos of their previous work. We hired them and they finished our project today. Justin and Thomas were professional and very easy to work with on this project. Their work was precise and so neat and tidy. Our front porch is now at the level of the threshold and all cracks were leveled, and caulked. We are so pleased with their work. I have included photos. The first 4 pictures are "Before" and the last 4 are "After".

Jamie was a pleasure to work with, and easy to get along with. When arriving to perform the work, he listened to our concerns and offered solutions. He was quick and through when doing the work. He did a fine job with sealing the areas that were cracked. Thank you!

Slab Jack Geo has to be the best in the business. Jerald came over, provided a quote to make my broken, tired driveway look soooo much better and then came and made it happen. I am elated with the job he did and the price was very fair. He saved me from having to put in a new driveway. I would recommend SJG to anyone in need of some very professional concrete repair work. They exceeded my expectations and I admire the work done every time I get in my car.

This is what old fashioned, top shelf, best-care-anywhere customer service is supposed to be like! If I could give 10 stars I would! From the quick response to my estimate request to getting the job completed everything was smooth, simple, quick and easy! A competing company gave me an estimate almost triple with only a one year guarantee - with Slabjack I have a limited LIFETIME guarantee! Great communication and high quality work ..... super happy, full stop!

Everyone I contacted was knowledgeable, authoritative, reliable and pleasant, from the estimator to office coordinator to technician. There was no pressure, I was given alternatives (including some DYI options), and the price was held to even though I am sure there were obstacles that were not accounted for. In fact, while there, the tech suggested an additional area of repair which I hadn't included in the bid, and he undertook that as a "customer goodwill" gesture. These folks do quality work and seem more like neighbors than contactors. Thumbs up, Slabjack!

The crew did great. The estimate was informative and included pictures with overlaid graphics of what was to be done. The repair crew was quick, professional, and thorough. I hope I don't need to do driveway repair again, but if I do, I will use this company again. I fully recommend them.

Upon examining my concrete slab that I thought needed raised up Jerry recommended that it didn’t really need to be done. I thought I needed to raise it to raise a vertical support that was holding up a heavy awning assembly. While here Jerry I was able to pry it up with a shovel and we put temporary support under it took no more than about 20 minutes I was amazed and there was no charge thank you so much.
