"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."

"From the initial phone call to the completion of the job Quality 1st provided top notch professional service. A couple points which makes this easy to write. Communication is key whether in person or via telephone and Q1 was exceptional in this regard at every point. Telephone conversations with customer services was pleasant and cordial, never rushed or snotty. Paul our salesman was here for quite a while answering questions and assessing our needs in the basement. Of only was he on time for our appointment he was about 10 minutes early too. The cost of this project was a good chunk of change for us but after too many times of shop-vac’ing water we knew it was time to bite the bullet and move forward with making life a little easier and not have the issue of when will we get water in the basement again hanging over our heads. I was impressed that Quality 1st uses their own products and has their own R&D facilities. As for the installation, enough cannot be said for the crew that was here. I got the call at 9am they would be here in 20 minutes and at 9:20 they were backing in my driveway. I met the foreman Mario and his 2 helpers. We went into the basement and they looked around and asked if I had any questions. We had almost everything out of the basement and what was left they covered in plastic. By 9:50am they were running the jackhammers. We have a 1,500 sqft ranch and these guys worked all day, they didn’t stop and worked their tails off. I can’t remember exactly when the jackhammer stopped but by 2 pm the channel was dug out and they were beginning to lay out for the channel that carries the water to the sump. About 4pm Kyle showed up to assess the job and see if I had any questions or concerns. We spoke about the job and we went downstairs to see the progress. He stayed on site for about 45 minutes after making sure I was comfortable with how the job was going. By 5:15 or so the job was completely finished. Before they left Mario went over everything regarding the sump system. As far as cleanup, this is a dusty job. Concrete dust is ultra fine and they did a fantastic job of not only sweeping but they also dusted off areas which were not covered in plastic. They left no mess to speak of., I was very satisfied with their work and attention to detail. It’s easy to nitpick any job at anytime and there is nothing I would call them out on. Finally as for the functionality of the sump system I wish I had a comment on that at this time. We’ve lived in our house for 25 years and until around Thanksgiving of this year (2018) we’ve only had water about 4 times. Between Thanksgiving (2018) and New Years (2019) we got slammed 4 times and nothing since. With the symptoms of how our basement got water, I feel comfortable with the system Quality 1st installed and am confident they will stand behind their work and warranty. We’re also happy this is transferable to the next homeowner when we sell the house and it is an excellent selling point when the time comes."

"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."

"Project went very well. I had a triple driveway and whenever it rained, there was always a puddle. Ricardo and his crew dug up the entire driveway the first day and also prepare it to pour the concrete the next day. The next day they poured the concrete and pitched it to make sure water would run off. They also did a great job stamping the concrete. It came out beautiful. My driveway is the talk of the neighborhood. I have the best looking driveway in the neighborhood."

Concrete Leveling questions, answered by experts

On average, a mudjacking repair lasts between five and 10 years, though it can sometimes last for well beyond a decade under ideal conditions. Its longevity depends heavily on several factors, including the condition of the underlying soil, environmental conditions like freeze/thaw cycles and erosion, and whether the root cause of the sinking, such as drainage issues, is resolved. Because it doesn't always fix the underlying problem of loose soil, mudjacking is often considered a temporary solution. Proper maintenance and evaluation can help extend its lifespan.

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

Concrete leveling can last anywhere from five to 10 years or more, and in some cases, it can be a permanent solution. The longevity depends on the method used and whether the underlying cause of the sinking is addressed. For example, mudjacking typically lasts five to 10 years, while polyjacking can last for 20 years or more. It's best to consult a professional for an accurate timeline based on your specific situation and any factors that could cause the issue to recur.

The method involves lifting settled concrete using pressurized cement slurry via drilled holes. This solves uneven surfaces and prevents further settling.

Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.
