"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."

"Pat and his team were, by and large, fantastic. They executed on all aspects of the original quote flawlessly. The ribbon pointing around the stonework, especially in the front part of the house, turned out very nice. We're extremely happy with how the masonry looks. It went so smoothly, we added additional work onto the quote to seal the concrete and touch up paint along the exterior of the house. The painting wasn't as neat or clean as it could have been - it's probably a little step above what I could have done. Mostly importantly, when we encountered a couple of problems along the way, they were responsive and went above and beyond to sort it out. I think they approached the whole project very well, and even worked with us on the price for the add-ons. All-in-all, super solid work from a super solid contractor. Highly recommended."

"Larry came out and did an analysis of our exterior drainage system, as we were having some puddling issues in the front and rear of our yard. We had just moved into the home a few months prior and Larry also did an analysis of our basement as we were having some concerns about the slightly bowed wall in our basement. Larry was very thorough and took a lot of time to go through the details of the exterior french drainage system he would install. He responded back to us in a timely manner and was extremely reasonable with their quote compared to other bids we had received from other contractors.
Larry and his team came out to the house and made quick work of a tedious job.  They took good care to keep the job-site as tidy as possible. Although Larry changed from the original plan, we felt comfortable with this as he was very thorough when explaining the reasons behind the change and we felt he had our best interest at heart. If we had any questions Larry was always available to answer them for us even when we called at 9pm.
We had a walkway that they had to cut through in order to run the piping for the drainage and Larry even added concrete to fix the walkway even though it wasn't in our original proposal.
We feel like with the work that was completed we got an excellent price and we have the peace of mind knowing that the job was done properly.

"We are absolutely thrilled by the work that was done by JMJ Landscaping.  They were able to reproduce exactly what we had requested.  We wanted a flagstone patio installed with an organic layout design that complemented the curved lines of our garden.  Since our yard has a downward slope, we asked for a low and sloping stone wall to be built on one edge of the patio and to actually level out a section of the yard so that it could abut the wall and in essence create level ground in the yard.  They finished off by seeding the newly leveled portion of yard and covering it with hay.  They completed the job in a very timely fashion at the price we were quoted.  My husband was very impressed that they obtained Wissahickon schist for the wall to mirror the stone that our house is made of.  The guys were extremely professional and really took pride in their work.  The new patio is absolutely beautiful and looks as if it was part of the original design of the house.  Although it was a little expensive the quality of the workmanship and supplies was well worth it and I have no doubt that this has increased the value of our property.  I would highly recommend JMJ Landscaping.

"They provided a free estimate which was substantially lower than the other three estimates I had been given. Because the concrete repair spanned my and my neighbor's property, they worked out a good deal for us to do both properties at a very reasonable cost. Four guys came out around 8am and everything done by noon. Fast, excellent work, concrete looks beautiful. Very fast, efficient, and fair - would highly recommend."

Concrete Leveling questions, answered by experts

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.

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

Most projects take 1-3 hours, with immediate usability after completion.

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

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.
