When excavation and grading are done right, the difference isn’t subtle. Water moves away from your foundation instead of pooling against it. Your yard becomes usable space instead of a soggy mess after every storm. And the basement that’s been taking on water every spring finally stays dry not because you added another sump pump, but because the grade is actually correct now.
That matters a lot in Glenolden specifically. Most homes here were built between the 1920s and 1950s, long before modern drainage engineering was standard. The clay and shale soil that runs under most of these properties doesn’t absorb water it holds it. When the ground around a 70- or 80-year-old foundation was never properly sloped to begin with, water has nowhere to go except down the wall and into the basement. Proper site grading changes that equation permanently.
The other thing that changes is what you can actually do with your outdoor space. A sloped, uneven backyard on a quarter-acre lot in Briarcliffe or Llanwelyn Gardens isn’t just an eyesore it’s wasted square footage. Once the land is excavated and graded correctly, that space becomes something you can actually build on, sit in, and use. That’s the real outcome here.
We’re based in Aston, PA a few miles down Chester Pike from Glenolden and have been doing residential excavation, grading, and hardscape work across Delaware County for over a decade. Our owner, Renato Spennato, is on every job. Not in the office coordinating actually on the job. Reviewers name him specifically, and that’s not a coincidence.
What makes us different from most excavation contractors in this area is the full-service model. Most dig crews stop when the dirt work is done. You’re left to find a masonry contractor, coordinate timelines, and hope everything lines up. We handle the entire project from land excavation in Glenolden through grading, retaining walls, and the finished outdoor space under one contract, with one team. For homeowners managing a commute into Philadelphia and a property that needs real work, that matters.
We hold an active Pennsylvania contractor license and carry a BuildZoom score of 102, ranking in the top 11% of more than 125,000 licensed PA contractors. That’s a third-party number you can verify yourself.
It starts with a site assessment. Before any equipment moves, our crew walks your property to understand the existing grade, identify drainage patterns, and flag anything that needs attention including what’s underground. In Glenolden, that last part matters. Many homes in the borough still have original cast iron sewer lines and mid-century utility layouts that don’t always match current maps. Pennsylvania law requires calling 811 before any excavation, and that call gets made on every single project before the first shovel goes in the ground.
From there, the scope gets confirmed and permits get pulled. Glenolden Borough has its own permit office at 36 Boon Avenue, and work that starts before approval results in doubled fees that’s a borough-specific rule that catches a lot of homeowners off guard when they hire someone who skips that step. We handle the permit process as part of the job, so you’re not navigating that on your own.
Once permits are in place, excavation and grading work begins. We size equipment for residential lots not oversized commercial machinery that tears up a quarter-acre yard. Our crew works clean, moves efficiently, and doesn’t leave your property looking like a construction site between visits. If the project includes a retaining wall, patio, or other hardscape, that work follows in sequence with the same team no handoff, no coordination gap, no waiting on a second contractor to show up.

Excavation work in Glenolden covers more ground than most homeowners expect going in. Site grading and drainage correction are the most common starting points especially on older properties where the original grade has shifted over decades of clay-soil movement and freeze-thaw cycling. But site preparation for patios, retaining walls, pool installations, and yard leveling projects all fall under the same scope of work, and we handle all of it.
For drainage and grading projects, our work includes assessing the existing slope, excavating to the correct depth and profile, establishing proper grade away from the foundation, and ensuring water has a clear path off the property. In Glenolden, where the borough’s zoning requirements specify that construction documents must accurately show drainage and water disposal systems particularly for pool installations that documentation is built into the process, not treated as an afterthought.
For site preparation projects tied to outdoor living additions, the excavation scope includes clearing and grading the build area, preparing a stable sub-base, and coordinating the transition into hardscape installation without a gap in the work. Because we handle both the excavation and the finished surface, there’s no version of this job where the dig crew grades it one way and the masonry crew shows up to find it wrong. The same team carries it through from start to finish.
Yes, most significant excavation and grading work in Glenolden requires a permit from the Glenolden Borough office at 36 Boon Avenue. The borough operates under the Pennsylvania Uniform Construction Code, and permit fees for retaining wall work typically run between $50 and $150 depending on project size. The important thing to know is that Glenolden Borough enforces a doubled permit fee for work that starts before approval is granted so if a contractor begins digging before the permit is issued, you’re the one who ends up paying for it.
For pool installations specifically, the borough requires that construction documents accurately show drainage and water disposal systems, as well as distances to lot lines and structures. That’s a documentation requirement that affects excavation scope and planning before a shovel goes in the ground. A contractor who’s familiar with how Glenolden Borough processes permits will handle this as part of the job not leave it to you to figure out after the fact.
Nationally, residential excavation averages around $3,975, with a typical range of $1,658 to $6,709 depending on scope, soil conditions, terrain, and disposal requirements. In the Philadelphia metro area which includes Delaware County and Glenolden labor runs 15 to 25 percent higher than the national average, and Pennsylvania carries a regional cost multiplier that pushes total project costs above what you’d see quoted in rural parts of the state. That context matters when you’re comparing estimates.
What affects cost most in Glenolden specifically is soil composition and project scope. Clay and shale soil is harder to work with than sandy or loamy ground it doesn’t excavate as cleanly, and it creates drainage challenges that sometimes require additional grading work to resolve properly. If your project involves drainage correction on top of basic excavation, or if the site prep is tied to a retaining wall or patio installation, the total scope will be broader than a simple dig. The most accurate way to get a real number is a site assessment that’s where the actual conditions of your property, not a general average, drive the quote.
The short answer is that the soil under most Glenolden properties doesn’t drain efficiently, and the original grading on homes built in the 1920s through 1950s was never engineered for modern water management expectations. Clay and shale soil holds water instead of absorbing it. When that soil sits against a foundation that was built before current waterproofing standards, and the yard isn’t sloped away from the house, every significant rainfall becomes a problem.
The fix isn’t a sump pump or waterproofing paint those address symptoms, not the cause. What actually solves recurring yard flooding and basement water intrusion is correcting the grade so water moves away from the foundation and has a clear path off the property. In some cases, that also means addressing low spots in the yard where water pools between storms. Proper excavation and grading work establishes the slope profile that should have been there from the beginning and once it’s done correctly, it’s not something you’re revisiting every spring.
For a straightforward grading or drainage correction project on a standard Glenolden residential lot typically up to a quarter acre the active work generally takes one to three days once permits are in place and equipment is on site. More complex projects that include retaining wall construction, significant site preparation for an outdoor living addition, or extensive drainage system installation will take longer, and the timeline gets confirmed during the site assessment before work begins.
The permit process through Glenolden Borough adds lead time before the physical work starts, so factoring that in when you’re planning your project timeline is important. Spring is the busiest booking window for excavation work in this area homeowners who dealt with drainage problems or basement flooding over the winter tend to move on those projects as soon as the ground thaws. If your project is weather-dependent or tied to a construction start date, getting the site assessment and permit process started earlier in the season gives you more control over the schedule.
Excavation is the process of moving earth digging down, removing material, and clearing a site for what comes next. Grading is about establishing the correct slope and surface profile so water drains properly and the ground is stable enough to build on. They’re related, but they’re not the same thing, and whether you need one or both depends on what you’re trying to accomplish.
For most Glenolden homeowners dealing with drainage problems, grading is the core service but excavation is usually required to get there. You can’t re-establish a proper grade without first removing the existing soil profile and reshaping it. For site preparation projects tied to a patio, retaining wall, or pool installation, both are typically required as part of the same scope of work. The site assessment is where that gets sorted out clearly what the property actually needs, in what order, and why so you’re not paying for work that isn’t necessary or skipping work that is.
We handle the full project excavation, grading, retaining walls, and finished hardscape with one crew and one contract. That’s not how most excavation contractors in the Glenolden area operate. The typical model is a dig crew that finishes the site prep and hands off to a separate masonry contractor, which means two timelines, two points of contact, and a real risk of the finished work not matching the site prep underneath it.
For homeowners on tight lots in Glenolden where most properties run up to a quarter acre and neighbor proximity is close that coordination gap creates real problems. If the grade doesn’t line up with the retaining wall design, or the sub-base isn’t prepared correctly for the patio that follows, you find out after the fact. Because we carry the project from the first dig through the finished surface, those gaps don’t exist. The crew that grades your yard is the same crew that builds your retaining wall and installs your patio. That continuity is what makes the finished result hold up the way it should.
