"Groundworks were contracted to encapsulate the crawl space, with a dehumidifier, intellijacks & sump pump. The inspector showed us pictures & videos of what the work would look like on completion, & explained how each solution would be installed. They tried to charge me more for vent covers until I showed them the contract covering this part. The foreman told me there was a reset button for the sump pump to be installed on an exterior wall, but they did not install it, instead said they would put in a service order. I haven’t heard anything about this issue yet. When they installed the moister barrier, they excluded the cement pads I was told it cost extra to have them covered. When I signed the contract, I was never told there would be extra charges for vent covers or cement pads to be covered. The contract I signed covered a complete encapsulation, but this is not what I got. This is a bait & switch. I would not recommend Groundworks."

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.
Concrete repair costs range anywhere from about $0.10 to $0.15 per linear foot to fill minor cracks, to about $6 to $14 per square foot to replace damaged concrete slabs. Repair costs vary widely depending on the size and type of work needed. For example, replacing 100 square feet of driveway will cost between $600 to $1,400, on average.
The average cost of mudjacking is around $5 per square foot of concrete, with most concrete leveling jobs totaling between $3 and $8 per square foot. The typical cost to fix a sinking portion of concrete slab with mudjacking is around $1,100. The price you’ll pay depends on the size of the concrete slab you need to be leveled, the accessibility of the slab, and the type of material your contractor uses beneath the concrete to lift it back into place.
In most cases, no, mudjacking is not possible as a DIY job. Not only do you need specialized equipment to cut into your slab and pump the cementitious material underneath it, but it’s also a challenging process, and the consequences of making mistakes include additional structural damage to your home. It’s possible to rent mudjacking equipment to attempt a DIY repair, but the risk of added property damage usually isn’t worth the money you’ll save on labor, especially if the concrete you’re lifting is a part of your home’s foundation.
Concrete contractors typically charge anywhere from $6 to $14 per square foot. Cost factors include job size, site prep, base material, accessibility, your location, concrete finish, and concrete thickness. Removal of existing concrete, asphalt, deck, pavers, and grass will cost anywhere from $1 to $6 per square foot. Homeowners can often save money by removing and disposing of existing pavers, decks, and grass. Breaking up and hauling away concrete and asphalt is difficult and time-consuming without the proper equipment and may be worth having the pros do that work.
