McGowan 1928 provides excavation and grading services across Long Island, helping homeowners, businesses, builders, and municipalities prepare properties throughout Nassau and Suffolk counties.
Complete Excavation and Site Preparation Services
Every project begins with understanding the property’s soil, elevation, drainage patterns, underground utilities, and intended use. Our clearing and site preparation services remove obstacles and create a stable working area for future construction.
Site excavation services may include:
- Land clearing and vegetation removal
- Stump, root, rock, and debris removal
- Topsoil excavation and earthmoving
- Foundation and building pad preparation
- Utility trench excavation
- Driveway and road preparation
- Rough and finish grading
- Soil compaction and erosion control
Why proper planning matters: Professional site preparation helps prevent unsuitable soil, improper elevations, and hidden site conditions from disrupting later construction.
Why Choose McGowan 1928 for Excavation and Grading on Long Island?
McGowan 1928 provides professional excavation and grading services for residential, commercial, and municipal properties throughout Nassau and Suffolk counties. Since 1928, our experienced crews have helped prepare Long Island properties for construction, paving, drainage improvements, landscaping, and broader site-development projects.
Every project begins with an evaluation of the property’s soil conditions, existing elevations, drainage patterns, underground utilities, accessibility, and intended use. Using company-owned excavation equipment, our team performs precise digging, earthmoving, land clearing, grading, and compaction to establish a stable foundation for the work that follows.
Clients choose McGowan 1928 for:
- Residential and commercial site excavation
- Rough grading and finish grading
- Land clearing and vegetation removal
- Foundation and building pad preparation
- Driveway, parking lot, and private road preparation
- Utility and drainage trench excavation
- Soil compaction and erosion-control planning
- Drainage corrections and improved water flow
- Coordination with paving, concrete, and site construction
- Experienced crews serving Nassau and Suffolk counties
McGowan can coordinate excavation and grading with clearing and site preparation, drainage and site work, asphalt paving, concrete construction, and other outdoor improvements. This coordinated approach helps ensure the property is properly prepared from the ground up.
Professional Grading for Drainage and Construction
Land grading is not simply about making a property look level. A custom grading plan establishes the correct slopes and elevations so water moves away from buildings, paved surfaces, and vulnerable landscape features.
McGowan handles slope grading, foundation grading, grading and compaction, and drainage improvement for residential and commercial properties. This work can help reduce standing water, soil erosion, pavement damage, and water intrusion around foundations.
Properties with high water tables or recurring runoff problems may also require a coordinated drainage and site work solution. Catch basins, drainage systems, and other water-management features must be positioned according to the finished grade.
Excavation Services for Long Island Properties
Our excavation and grading capabilities support projects of varying sizes throughout Nassau County and Suffolk County. Common applications include new driveways, parking lots, private roads, building additions, outdoor living spaces, landscaping projects, and commercial development.
Modern excavation machinery and experienced equipment operators allow our team to complete precise digging, trenching, earthmoving, and grading while protecting surrounding property whenever possible.
Before excavation begins, underground utilities must be identified. New York 811 instructs property owners and excavators to request utility marking at least 48 hours, but no more than 10 working days, before digging.

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

And as always, thank you for getting it all done on time and at very reasonable rates.

“I’m the President of an HOA in Bohemia, NY and a retired Union General Labor Foreman in NYC and on Long Island. Over my 40+ year career, I’ve worked with many contractors — and hands down, John McGowan & Sons is one of the best I’ve had the pleasure to work with.
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.
If you want a great company to handle your project, no matter how small or large, you definitely want JOHN McGOWAN & SONS to do it!!!!”
HOA Road Improvement Project
“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.”
HOA Road Improvement Project
“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.”

The finished product is clean, polished, and exactly what we were hoping for. You can tell they take pride in doing a thorough job. We’re really happy with how it turned out and wouldn’t hesitate to recommend McGowan & Sons to anyone looking for quality driveway work.”
