"It was a complex project. They were very careful with their procedures and raised sunken concrete sections next to the house and around a pool to allow for drainage. They filled the major cracks. They were courteous and on-time over several days. After many years the water in the basement problem has been resolved."

"C&J did an incredible job completely gutting and remodeling our 1895 farmhouse. This was a huge 8-month job with the variety of complications and required changes an old house can throw at you; throughout the process Craig and Jerry offered excellent design suggestions, collaborated very well with our architects, worked diligently to stay on budget, and each day demonstrated craftsmanship and professionalism of the highest level. C&J’s team of subcontractors and designers are excellent too. These people are the best the building trade has to offer: conscientious, skilled, creative, and a pleasure to work with. Hoping to have them back soon to remodel the guest cottage and garage! See Photos here: [*** Link removed ***]"

"When I contacted All Dry I was gun shy. This would have been my 4th contractor I would have to deal with. All theee prior told me something completely different and tried to take advantage of my limited knowledge. From the get go, All Dry Basement made me feel extremely comfortable. Todd and his team answered my questions thoroughly and were always available for my questions . The work that was done was amazing, he was punctual everyday and worked some nights until 8pm until the work was completed. It is like a different world in the crawlspace, the smell is gone, all of the debris were cleaned out and. Brought to the dump, a vapor seal was installed, a dehumidifier for the moisture, one entryway to the crawlspace was closed up and the main entrance was re worked for easier access. Blocks from the foundation were grouted because the blocks were dead, , floor joists were spay flames and the House is now Warmer. I couldn’t be more please wth the quality of work All Dry Basement did at my home. They were professional and amazing and I would 100% recommend them. My stress level has decreased a million percent because after two years I found a company that was honest from the get go and their work shows it!!!! HIRE THEM FOR YOR CRAWLSPCE AND BASEMENT NEEDS. Do not look any further."

"This was a very involved plaster repair and remediation job, in a very old house. Grady is the only person (or company) who was willing to take on the job and drive all the way from Pennsylvania to our home in Northern Virginia. There are very few people who do this kind of work anymore (we really searched) and he is an expert in his field. We needed to work around his schedule, because he is in demand in the tri-state area, so it took awhile to schedule the work to begin... but it was worth it."

House Leveling FAQs, answered by experts

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation. 

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

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.

Trenching and boring are two distinct methods for installing underground utilities. Trenching involves digging a channel using equipment like an excavator, trencher, backhoe, or shovel. While it is a simpler process, it causes significant disruption to the surface, landscaping, and surrounding ecosystems.

Boring, also known as directional boring, is a less invasive alternative that uses a drill to create a tunnel for utility lines without disturbing the surface. This method is more precise and is ideal for installations that need to go underneath buildings, roads, or bodies of water. Although boring is less disruptive, it is generally more expensive than trenching.

Polyjacking can be a permanent solution to sunken concrete if you also address the underlying issue—like poor drainage—at the same time. The polyurethane material itself can last as long as or even outlast the concrete you’re lifting it with. Your sunken concrete issue will likely return if you don’t couple polyjacking with proper drainage to prevent future soil movement and sinking.
