Customers say: Quick response

"This is a long overdue review and brought to my attention by Mike when he requested a review for a retaining wall just completed. Three years ago MFS Masonry reconstructed our pool deck and pool area. I did not know what exactly I wanted except that I wanted it to look great. He has such experience that he was able to suggest a lovely plan for the deck to surround our 16 by 32 in ground pool and river rock for landscaping. His crew worked tirelessly breaking up and removing concrete, shaping and reinforcing for the new concrete deck, and making it look perfect. They were prompt and respectful of our property and completed the job in two or three days. More to point, that pool job was the third time they did a job for us. Can't recommend them enough."

"Tim and Jake Hillman of Diggs Build Technologies are the right guys to fix properly your home-foundation problems. They assessed the issues with my leaking and bowing basement wall, and patiently explained why replacing it was the right solution (and merely propping it up wasn't). They carried out the work in early summer 2025, along with an exterior sump pump, and sorted out problems related to rotten beams they encountered along the way. I highly suggest you remain on site on their working days so you can learn about and consult on the work, which is interesting in itself. Naturally such great guys are in high demand, but they're worth the wait and expense."

"We have hired Amedeo several times over the past 10+ years living in multiple homes. Most recently he transformed our backyard into the most stunning oasis we could have ever dreamed. He is a creative visionary and whatâ s more, the process and workmanship match! He created for us the most beautiful stamped concrete pool patio surrounding our gunite pool, the most architecturally stunning waterfall/grotto combination, the most uniquely stunning poured concrete staircase, an outdoor kitchen/bar, fire pit, walkways and privacy wall. We could not be happier! It is clear he takes Pride in anything he attached his name to. From start to finish, you want him to handle your project!"

"The contractor is very good.  They are very punctual.  They provided the engineering drawings for the township, provided a detailed plan to replace the bowing wall, and the pinning of two other walls for structural support and the basement entrance.  They also provided support for a high water table issue
The crew was one of the best I have ever seen.  They came, worked extremely hard and completed the job on time and as the building inspector said," a stellar job".
They covered all objects in the basement to minimize the dust, and moved the washer and dryer, reconnecting them in their new locations.

Concrete Walls FAQs, answered by experts

Newly poured concrete is prone to small, fine cracks within the first 30 days of installation, but most noticeable cracks will disappear within that time frame. If a crack is greater than 1 inch, consider contacting the person who installed your wall to inspect the job.  

With proper installation and sealing, both poured concrete and cinder block walls can be durable options for your yard or home. Poured concrete walls do offer more durability and strength, but cinder block walls are less expensive to build and DIY. A concrete wall costs an average of $6,500.

Yes, you can pour concrete if it rained the day before, but you’ll need to drain the construction site to ensure there isn’t standing water where your slab will sit. You might need to manually remove any puddles and set up drainage on your site to dry it before pouring. Moist soil won’t be an issue, but standing water will throw off your concrete mix ratios. Additionally, ensure there isn’t more rain expected in the near future before you pour.

Labor and pouring adds between $8 and $18 per square foot to your total for concrete delivery. Especially for larger projects, it’s usually a good idea to hire a professional concrete delivery company when it comes to installing concrete surfaces even though it will undoubtedly cost more to hire a pro to do the work for you.

Costs depend on material type, labor rates, and additional features like decorative finishes or reinforcement.
