Request A Free Quote
Concrete slabs play a critical role in the stability, safety, and long-term performance of residential, commercial, and industrial properties. In New York City—where soil movement, traffic vibrations, harsh winters, and aging infrastructure are common—quality slab construction and concrete repair are essential for preventing structural issues. At John McGowan 1928, we specialize in concrete slabs, concrete leveling, concrete floors, garage floors, pool decks, driveway segments, and concrete slab sidewalks.
Our team uses state-of-the-art equipment, high-strength mixes, and advanced stabilization methods to deliver durable, code-compliant slabs tailored to NYC’s demanding environment. From Mid-Rise Construction projects to slab replacements in Brooklyn backyards, our services meet all NYC Department of Buildings requirements, Construction Codes, and safety standards.
Concrete Slab Installation for Foundations, Floors, Patios & Pool Decks
Every slab installation begins with proper subsurface and soil stabilization—especially in areas with expansive clay soils, water or sewer line proximity, or high machine and traffic vibrations. We assess conditions, prepare the base, and use proven forming techniques to ensure long-term slab performance.
Applications We Service
- Foundations, radiant floor heating slabs, and structural concrete floors
- Pool decks, patios, and cracked or uneven deck repairs
- Garage floors, basement slabs, and commercial flooring
- Concrete slab sidewalks and small-scale site slabs
- Industrial slabs requiring pumping services or specialized reinforcement
Our slabs are constructed using 4000 PSI concrete, high-quality aggregates, and reinforcement systems such as Quik Hangers™ Rebar Hangers, ensuring durability and stability. We also offer environmentally friendly options and green technologies that meet New York’s sustainability and energy code requirements.

They’ve built their reputation on trust, competitive pricing, and skilled technicians who complete every project with care.

Improved Safety
Resurfaced pavement eliminates tripping hazards, smooths potholes, and enhances visibility with new striping. It also minimizes water pooling and surface irregularities that can cause accidents. For commercial properties, proper parking lot striping and resurfacing create a more organized and compliant layout, especially in high-traffic work zones. When paired with noise reduction equipment and careful work zone safety planning, resurfacing projects contribute to an overall safer environment for both pedestrians and drivers.
Durability and Longevity
Using hot mix asphalt, asphalt paving techniques, and asphalt crack filler, resurfaced pavement can endure heavy vehicles, freeze-thaw cycles, and foot traffic. Incorporating recycled asphalt materials or permeable asphalt also supports long-term durability while improving sustainability. With proper asphalt maintenance, resurfacing protects against pothole repairs, crumbling sections, and degradation from rock salt or calcium magnesium acetate during winter. This makes it ideal for asphalt driveway repair, paving jobs, and full-scale commercial resurfacing.
Cost-Effectiveness
Compared to full replacement, resurfacing reduces the cost of asphalt repair significantly. Property owners can save 40–60% while achieving a refreshed, durable surface. The use of special machinery and efficient asphalt production processes makes resurfacing faster and more economical. Contractors like John McGowan & Sons, fully licensed & insured, provide professional asphalt solutions without compromising quality, ensuring long-term savings and increased property value for residential and commercial clients alike.



Concrete Leveling, Lifting & Mudjacking for Sunken Slabs
New York properties often experience slab settlement caused by soil washout, voids, erosion, frost from polar vortex conditions, and aging infrastructure. These issues create trip hazards, drainage problems, and uneven surfaces that worsen over time.
Advanced Repair Methods
- Polyurethane foam lifting / polyurethane foam leveling (lightweight, fast-curing)
- Mud jacking and limestone-based grout injection
- Hydraulic pressure injection for deep void filling
- Total concrete leveling and self-leveling treatments
- Diamond grinding, concrete sawing, and precision concrete removal for resurfacing
We determine whether the slab requires leveling, void filling, or full replacement based on structural integrity, material condition, and NYC DOB inspection requirements.
Repair, Restoration & Specialized Slab Services
Some projects require advanced expertise—especially for commercial clients, emergency services, or complex projects. Whether the job involves slab curl correction, cracked concrete repair, or stabilizing large commercial floors, we bring decades of industry experience and precision workmanship.

John and Jim,
I am writing this letter to let you know that I am moving on in a pursuit of a new opportunity and I wanted to express my gratitude for your support during my time with Konica.
By depending on the services of McGowan we were able to streamline our local services for a reasonable cost and at a critical economic juncture we maintained momentum and continuity. Thank you so much for all the great projects we were involved in together from the concrete work, asphalt paving work, retaining walls, drainage projects and many others. I cannot thank you enough for your quality work and helpful advice.
If you ever need a recommendation please do not hesitate to use my name. When construction projects come up in my new position I will be sure to call McGowan first.
Commercial Project
John, I wanted to thank you for taking the time to meet with me last week. I truly appreciated your creative ideas on how to significantly reduce some of the maintenance costs associated with our plant in Glen Head, NY.
It is the choice of vendors like McGowan that helped Halm Industries become a world leader in envelope printing equipment. While Halm Industries pursued global presence and success, McGowan helped maintain our local plant’s infrastructure seamlessly. Please accept our gratitude for the 28 years of reliable, on time and always within budget projects and we look forward to your continued support.
We will provide the management team with your ideas to reduce maintenance costs and get in touch soon.

P.S. I also wanted you to know that the retaining wall and drainage project completely solved the problem with the floods.

They handled our complex’s street replacement project with absolute professionalism. From James, John, Eileen, and Jessica to the extraordinary group of hardworking men they employ — their professionalism, knowledge, experience, and courteous manner truly stood out.
This company will get your project done in a timely fashion and on schedule, no matter what it takes — and that’s exactly what I experienced.

“J. McGowan just completed a beautiful improvement on our small private lane on the North Shore of Long Island. The shared private road was in poor disrepair, and with McGowan’s expertise and easy lead time, the job came out gorgeous. All resident neighbors were very happy with the result.
The office staff was always responsive and considerate, and the workers on the job were polite and kept the job site neat and clean. The pricing was also very good compared to other bids we received.
I highly recommend this paving contractor.”

“John and his team did a great job replacing our old retaining wall, stairs, extending our front porch, and repaving our driveway at our home on the North Shore of Long Island.
John McGowan & Sons were recommended by a friend in the neighborhood after seeing the beautiful work they had done at their home. A job that I thought would take weeks was done in just 10 days — start to finish.
When we thought there might be an issue with an old tree being in the way, John had someone take it down the same day so his crew could keep working. When we suspected a potential problem with the water main, he had his plumber there immediately to ensure no damage would occur. And when our outdoor light stopped working, his electrician showed up within the hour to reconnect it.
They really went above and beyond to get the job done right, on time, and at the exact price quoted.
I highly recommend John McGowan & Sons to anyone looking for professional masonry work.”
