Mark was very up front on what result he might be able a achieve, which I really appreciated. And, the result he did achieve was OUTSTANDING!!! Not cheap but well worth the results!

Outstanding job. Very quick turnaround and completed the project in less than one day,

I was very pleased with the whole process of working with A-1 Concrete Leveling. I contacted several companies about the work (and received many different assessments, prices, proposals on how to solve my issues) before making my selection, but I made the right choice with this company. I was not able to meet Mark when he came by to check out my driveway and walkway, initially, which is something I usually like to do with new contractors. But, Mark came when he said he would and left an estimate, drawing and details for me to review. I then corresponded with him by email several times to ask follow-up questions, to which he efficiently replied with more information. I felt comfortable knowing what to expect and also that I needed to be mindful of upcoming freezing temperatures during which the work could not be performed. When I finally made my decision in late November and informed Mark, he promptly added me to the schedule. On the day of the work, two crew members showed up during the timeframe I was promised and began prepping things. I discussed the scope of work with one crew member. Communication was easy and I felt listened to. Shortly thereafter, Mark arrived on-site and he went over things with me. He was very professional and personable. He stayed at the job for the next couple of hours while the concrete was lifted. The crew finished after he left and also within the timeframe quoted. When I saw the results, I was extremely pleased. It met my expectations and they had solved our problems. Our walkway tripping hazard was no more. The sunken gap between our driveway and house/garage was gone. I would recommend this company to anyone who needs similar work done as they deliver high quality results, good customer service and are responsive.

Very satisfied! Arrived on time, completed the work professionally, cleaned up after the job was complete. We could not be happier. Highly recommend!

Excellent! Great people to work with - very happy with the result.

A-1 Concrete Leveling did an outstanding job. Mark was timely and very professional. I first contacted him through the website and he provided a rough estimate based on the information I provided. He then did a site visit and provided a formal written estimate. He was able to schedule me within the week, showed up on time, and worked quickly. We were very pleased with the leveled steps and I strongly recommend him.

They came and examined the scope of work and gave me an estimate . I was told there could be an additional 400 required if they found the empty space underneath the pool deck to be larger than they anticipated. The day of our appointment, they came in and very efficiently and neatly repaired our sunken pool deck. The total cost of our bill was the exact amount of the estimate. We will defiantly use them again and recommend them to anyone that asks.

Great. Looks good.

Did not use services. First response was immediate. After providing information that was requested I did not receive a reply whatsoever for over a month. I called, emailed, and sent a request form in multiple times in that time period.

I submitted a request for estimate via website and attached photos - very straightforward process. Mark was responsive and professional, answering my many questions and keeping me updated with the progress (we had to reschedule once due to rain). Price was a bit higher than other companies I contacted, however this was more than made up for with Mark's outstanding customer service, he obviously knows what he's talking about and stands behind his work which is warrantied as well. Thank you, Mark.

Poorly. See above.

I didn't get a response from A-1 until I sent in photos.  Once I did, they were very quick to reply. They said there was crack in slab and that they couldn't help me. They recommended pouring a new driveway to resolve the issues.

Within 4 days of my initial contact with Mark, he and one of his team came to my home ready to perform the work.  It was done quickly and they even added some dirt and grass seeds in an adjacent area to correct the slope.  Mark noticed that underneath my porch was a large void, and suggested filling it as well.  Seeing a neighbor's porch starting to move a bit away from the front of his house was all I needed to agree to that additional cost.  All was cleaned up and completed in short order.  I hope to not need this type of work again, but if I should, it'll be Mark's company that I'll hire.

I'm not sure where these contractor get these prices from, clearly they pay themselves as much as they wish, judging from the verbal quote for one concrete step for over $800. I can't imagine how much they may overcharge on other projects.

I never got a response and I will be trying other companies.

Excellent Job! Crew was on time, very professional, and cleaned the entire area after work was completed. Job came in under budget and received an Angie's list discount.

I contacted this company via e-mail and they asked for pictures..  I did e-mail pics   the next day and have yet to hear back from them.  Not good business

Note - they are very busy, so get on their list early as once Spring hits they are hard to get.
Due to weather, the job got rescheduled a few times ( no problem really),
but they came out and did an awesome job.  The concrete was level, flush
with the sidewalk and none of my landscaping was damaged in the
process.  I was not home for the work, but everything was back in place/ and clean when I arrived Friday evening.   I was able to pay with my credit card and Mark informed me of another issue he noticed regarding my storm drain.   A good heads up which I appreciated.  Overall, a very good experience.
Note
- they need access to a hose bib and electricity to execute the
leveling.  All my utilities were off and back in proper order.

About two years ago the concrete porch on my 42 year old house developed a crack probably due to soil settling beneath it.
At first it was just a minor crack but it eventually expanded causing the porch to sag about 2.5 inches in the middle. The fact that
the porch has three columns that supports a substantial gabled overhang made this major concern.
I did some checking and found it would cost between six and eight thousand dollars to replace the porch.
While researching other options, I came across a process called mudjacking. The process entails strategically drilling holes in the affected slab and pumping in slurry which then lifts the slab. The slurry eventually hardens providing a stable substrate beneath for the slab.
After researching some companies I contacted A1 Concrete Leveling. Mark Howley came to my home and did an evaluation and determined mudjacking would work.
The following week Mark arrived on schedule. In about 4 hours he leveled the slab, filled in the cracks, ground the holes he drilled flush with the surface and completely cleaned the area.
I am pleased with the work especially considering it cost me substantially less than what replacing the slab would have set me back.

Contacted A-1 through Angies List to get a free estimate on leveling a concrete pathway between my front door and driveway. I live in Ashburn just down the road from Herndon.   Provided a description of the work to be done as well as photos.  Never received an acknowledgement or estimate.  Two weeks later, contacted A-1 through their website, and provided the same information. One month later, still waiting for a response. They are obviously not interested in my business.  If you get a response, good luck to you.
