"KN Remodeling redid my floors, removed a wall and got my JADU permitted, plus many more random fixes. Whatever project I threw at Nathan and his team he got done. They were great and I would use them again."

"The adage “You get what you pay for” rings true with MF Construction. When we were in the market for a general contractor to build our two-bedroom/two-bath ADU in San Marino, we interviewed several general contractors. Mike Maman of MF Construction was one of them. Mike showed us several of his projects as well as his own custom home. We were extremely impressed with the end results. After reviewing several competitive bids, we selected Mike because of his 40+ years of experience in building high-quality homes. During the construction of our ADU, Mike was just a text or phone call away. He kept us informed of upcoming events and visited our job site almost daily, sometimes more than once a day. He was present at all 12 of the City inspections. Every step along the way, we noted the high quality of materials Mike uses from the Ganahl lumber to the thick insulation and roofing paper to the copper pipes and shower hot mop, and mold-resistant drywall. Mike uses materials which meets or exceeds code requirements. Everyone on Mike’s team is extremely skilled in his/her craft, many having worked with him for decades. Mike is old school and does not take any shortcuts. Along with high quality construction and materials, Mike is extremely efficient. Our ADU was completed in four months, as promised. Progress was made every day. From the rough work to the finishes, Mike scheduled his team members just in time which resulted in an extremely efficient and smooth workflow. Mike builds with his heart. His passion is infectious which inspires his team members to do their best work. The results are evident in the finished product. Our neighbors and friends are extremely impressed with the quality and build of our ADU. If you value a well-built home and appreciate attention to detail, you will not be disappointed with Mike Maman. You WILL get what you pay for with MF Construction."

"We had excellent experience with Alpha Structural. Charlie Rosenkranz came to see the property and advice. He checked the structures all around and looked in the basement as far as possible beyond the ducts that were filling up the space and would require tunneling to get to some areas under the building. Communication was excellent. He's knowledgeable and experienced. We appreciated his professional no pressure approach and answering our questions. The front main duplex needed Seismic Retrofit; it wasn't bolted and had cripple walls. There were suspect areas in the foundations that would have to be tested when bolting, to see if the concrete is in good shape. After we agreed to their proposal have the work done we scheduled a range date. They had to submit to the city plans for a permit to do the work and wait for the permit to be issued. While doing the retrofit we found out that the foundation in the front corner was damaged and that the building has sunken and was not level at that corner. Charlie worked out the details and bid for the additional work of Partial Foundation Replacement, Posts/piers, and Jack Lift the corner to level it. He explained the details and what's involved to my satisfaction. Alpha obtained the permit for the work and proceeded. The work crew did excellent work. Jose Morales was the Project Supervisor. They completed the work at a good pace, including the delay for the additional work permit, without complications or complaints from the neighbors. The place was left clean. The work was approved in the inspection which they requested and scheduled with the city. The communication with everyone at the office was also very good. We're very pleased with the experience."

"From start to finish our experience with Foundation Works was top notch. We did contract them to bolt the foundation on our 1921 Spanish Bungalow home and repair some minor foundation cracks in a 1950's addition. Prior to calling Foundation Works we had two other estimates for work, one was in line with the quote provided by Foundation Works and one was higher with a few additions to the work. So I would say their price was in parity with others. Myron did our initial inspection and spent a lot of time crawling around under our home and doing a very detailed inspection. He spent a long time sitting with us afterwards discussing what he discovered and what he recommended. He was very patient with our many questions. When we tried to add some additional work reinforcing what looked like some long term slippage on the peers under the house he carefully informed us of the history of how houses like ours were built and why we did not need to spend more money doing this repair as it wasn't slippage but rather just how it was built. Once we accepted the bid FW was able to start work quickly. They worked cleanly and while they don't clean up every day before going home they also don't leave a bad mess and the work was all in the backyard so a few piles of tools was not a big deal at all and was painless. The team that did our work was professional, friendly, and efficient. When we had questions they were always there to answer. When we had one (very small) issue related to the nails originally used in the 1920s to hold the corner floorboards in which had jumped up a bit due to the installation of blocks needed to support the bolting in a few places, they stopped work, immediately fixed the issue and adjusted how they worked so it didn't happen again. When the work was done you wouldn't even have known they were here. The yard and all entry points to the crawl space were spotless. The Burbank city inspection was a few days later, they handled it completely and we never needed to worry about a thing until they handed us approvals. The back office and payment process was professional, pleasant, and very low touch. I can't recommend this company more highly."

"I found out about RET Construction Corp through reviews at another well known service website. From initial consultation to final construction, Kevin was great at explaining what was going to happen, design options, and providing strategic context for various decisions I had to make. A modern high-ceiling single-story main house with a detached ADU was built. People are always complimenting the house. Pricing was very competitive. The value for money was even better. You will not go wrong with choosing RET Construction Corp for your project."

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

House Leveling questions, answered by experts

The average cost for mudjacking is around $1,200, though prices can range from $300 to $3,400. On a per-square-foot basis, you can expect to pay between $3 and $8, with an average of about $5 per square foot. The final cost depends on several factors, including the square footage of the concrete, the type of slab, its accessibility, whether it is load-bearing, and the type of material used to lift it. Generally, lifting a driveway, small patio, or sidewalk is less expensive than lifting a slab foundation or garage floor.

Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.

Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.

It’s best not to perform mudjacking in the winter unless the ground temperature remains above freezing. Freezing temperatures can cause the slurry to harden too quickly, compromising its strength and longevity. Concrete is also more susceptible to cracking and splitting in cold temperatures, so there’s a higher risk of damaging the slab during the drilling and lifting process in winter.

Yes, you can mudjack cracked concrete, but the cracks will need to be repaired once the concrete has been leveled. If the concrete is severely cracked in multiple places, replacement may be a better option, but for less severe cracking, mudjacking is a good solution as long as cracks are correctly caulked and sealed.
