"I hired Todd to do some Concrete Leveling at my 68 year old home. The cement on my porch had sunk noticeably which had me concerned. Todd did a very good job at a reasonable price. He was very thorough and conscientious. I would highly recommend him for anyone who needs that type of work done."

"My crawlspace needed structural repairs to my wood framing and piers, an internal french drainage system to stop water intrusion, as well as installation of a 10mil floor liner to help keep moisture levels down. FD was EXTREMELY professional from my initial call and on-site appointment, to the guys doing the installation. I was kept informed throughout the entire process so there were no surprises. I HIGHLY recommend Foundation Doctor for any crawlspace work!"

"They had a drill malfunction and the supervisor, Craig Adams, expected me to clean up hundreds of grease spots off my porches and walls. He would not schedule a clean-up team to come back and clean the mess rather the technicians spent a few hours scrubbing the spots. However, they did not come up. The porches look considerably worse. Since that time, they have returned and made an effort to clean up the concrete. The front porch has now been completed, and they are returning tomorrow to work on the back porch."

"Josh and his team did a great job. They were prompt and fast. Josh was very patient with me as I deliberated my choices for slab leveling contractors and answered all my questions. The results are great and I saved nearly 2/3 what I would have paid with a competitor. He also wisely rescheduled service when several days of rain would have meant trenching up my yard with the equipment."

Concrete Leveling FAQs, answered by experts

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

Mudjacking is suitable for sidewalks, driveways, patios, and nearly all exterior flat structures. However, it may not suit severely damaged or heavily cracked areas.

There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.

The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.

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.
