"am writing to express my sincere appreciation for the outstanding service provided by Corey throughout my recent basement sealing project. From the very first interaction, Corey demonstrated professionalism, courtesy, and an impressive depth of knowledge. His ability to clearly explain the scope of work and answer all of my questions put me at ease regarding this significant and costly undertaking. What truly set Corey apart was his patience and dedication, even after the project was completed. He remained available to address my concerns and ensure that I was fully satisfied with the outcome. His thorough approach and commitment to customer satisfaction were instrumental in my decision to move forward with your company, even at a higher cost. It’s rare to encounter such a level of integrity and care, and Corey’s efforts have made a lasting impression on me. It’s thanks to professionals like Corey that I have full confidence in the quality and value of your services, and I would gladly recommend ground works to others based on this experience."

"Essex and Morris did an exceptional job taking our dated, crumbling front property and making it look like a new home was built. The end result was a beautiful new concrete side walk, asphalt driveway, paving stone walk way and refaced front porch. The demolition and reconstruction of the entire project was timely and discrete, communication was very open. The entire team from the guys on the crew right up to John Trezza Sr himself were all professional and very pleasant to deal with from a business standpoint to a simple “Good Morning” each day. I would highly recommend Essex and Morris to anyone looking for a project of our size, or smaller or bigger, that wants a group they can trust with an end result you’ll love for years to come."

"We had known about this problem for some time and had also had a structural engineer evaluate our situation.  We may be putting our house up for sale soon and decided it was finally time to get the wall fixed.  Armed with my own research and the engineers evaluation, we searched for a contractor to perform the work we knew we needed to have done.  Upon contacting Foundation Experts, Larry got back to me very quickly and we set up an appointment for him to inspect the wall.  He was VERY thorough in explaining what needed to be done to stabilize the wall to prevent any further movement/damage.  He said we should have the wall "pinned".  He quoted us $4000 to do the whole job (10 pins along a roughly 25ft. long wall).  They also designed the system so that the re-bar would pass through the top course of block and attach to the house sill plate above the wall to help lock it in place.  
The price was on par with most other estimates (slightly cheaper actually), but we decided to go with Foundation Experts mostly because they were very thorough with their evaluation, were honest (I was armed with a lot of info about our situation and felt very confident that what he proposed to do was exactly what needed to be done) and they did not pressure us at all.  I also really liked the fact that they routinely work with engineers and felt that they had a better grasp on executing the work over other contractors we contacted.  They also will work with the township if permits are needed.
We scheduled for the work to start the following week.  Their team took about 2 days to do the work.  They were very professional and did not make a mess at all.  They put plastic up to prevent concrete dust from getting everywhere in the basement and cleaned up thoroughly.  Larry was present during the bulk of the work and made sure that everything went smoothly.  They even worked with us on the payment method.  He made it very clear if we have any issues/concerns or questions to call them anytime.  He also stressed that if we sell the house and potential buyers have any questions/concerns to contact him and they will work with us as best they can.  
The wall is now fixed and my wife and I feel better knowing that our wall won't come crashing down during then next heavy rain!  We also feel better knowing that we won't have to worry about foundation issues coming up if/when we sell our house.  All in all, it was a great experience!

Concrete Leveling questions, answered by experts

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

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.

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.

Costs range from $500 to $1,500, depending on the size and condition of the area.

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.
