When excavation is done right, you stop fighting your yard. Water moves away from your house instead of toward it. Your retaining wall actually holds. Your patio doesn’t sink after the first winter. That’s what proper site work looks like in Aldan, where nearly a third of the homes were built before 1950.
Aldan’s clay-heavy soil is the root of most drainage problems on older properties throughout the borough. Clay doesn’t drain it holds water, expands when wet, contracts when dry, and shifts everything built on top of it. If your grade isn’t accounting for that, every heavy rain is working against your foundation. Getting the excavation and grading right from the start is what keeps that cycle from repeating.
The lots here are also tight. Row houses, attached homes, close property lines these aren’t conditions where we can just bring in a big machine and go to work. Precision matters. Every grading decision affects how water moves across your lot and potentially onto your neighbor’s. That’s the kind of detail that separates a contractor who knows Aldan from one who’s just passing through.
We’re based in Aston, PA close enough to Aldan that we’ve been working in these neighborhoods for years. We handle excavation, grading, site preparation, retaining walls, and finished outdoor spaces with the same crew from start to finish. That matters because when one team digs the ground and builds what goes on top of it, nothing gets lost between trades.
Renato Spennato runs the business and stays involved in the work. That’s not a tagline it’s just how we operate. Homeowners throughout Aldan and Delaware County consistently mention that he shows up on time, communicates clearly, and doesn’t disappear after the deposit. In a borough as tight-knit as Aldan, where word travels fast on Nextdoor and neighbors notice who’s working on your property, that kind of accountability matters.
We hold a Pennsylvania contractor license and carry a BuildZoom score of 102 placing us in the top 11% of over 125,000 licensed contractors in the state. That’s a third-party number you can verify yourself before making a single call.
Before any digging starts, we assess the site. Soil conditions, existing drainage patterns, lot lines, and what you’re planning to build on top all of it factors into how the excavation gets planned. In Aldan, that also means understanding the borough’s terrain modification permit requirements. Under Aldan Borough code, it’s unlawful to grade, fill, or excavate without a permit, and work that affects stormwater drainage which is almost all of it requires separate approval. We handle that process, not you.
Once permits are in order and PA One Call (811) has cleared the site, excavation begins. For most residential projects in Aldan, that means working in tight quarters small lots, close neighbors, and in some cases attached homes with shared drainage considerations. We bring equipment sized for the job, not oversized machines that tear up a residential property. The goal is to move what needs to move and leave the rest of the site clean and stable.
After the dig, we grade with drainage as the primary outcome. Slope away from the foundation, compacted base layers, and a finished grade that works with Aldan’s stormwater system. If the project includes a retaining wall, patio, or other outdoor work, that builds directly on top of what was just graded same crew, same standards, no transition gap between phases.

Residential excavation in Aldan isn’t one-size-fits-all. The combination of clay-heavy soil, aging housing stock, tight lot lines, and active borough code enforcement means the work has to be planned carefully and executed precisely. We offer site clearing, terrain reshaping, foundation excavation, drainage grading, land grading for retaining walls and patios, and full site preparation for outdoor living projects. Every project starts with the soil conditions and drainage requirements specific to your property.
Aldan Borough holds an EPA-regulated MS4 stormwater permit, which means drainage-affecting excavation and grading work has to comply with the borough’s stormwater management standards not just look right, but actually function correctly within the system. Our crews understand this framework and design every grading plan around it. That includes making sure surface water drains away from structures, that no soil or debris ends up in the stormwater system, and that finished grades don’t create unstable slopes or direct runoff onto neighboring properties.
For homeowners planning larger projects anything approaching a half-acre of disturbed area Aldan Borough requires a bond of at least $10,000 in addition to standard permits. We’ll walk you through what applies to your specific project so there are no surprises when you go to pull the permit. The goal is a finished site that passes inspection, holds up through Pennsylvania’s freeze-thaw season, and doesn’t create new problems down the road.
Yes, and it’s not a simple one-page form. Aldan Borough code makes it unlawful to pave, fill, strip, grade, or regrade any land within the borough without first securing a terrain modification permit. On top of that, any work that disturbs, modifies, or affects the natural flow of stormwater which includes most excavation and grading requires its own separate permit approval. Both permits involve the borough’s Zoning Officer and, in many cases, the Borough Engineer.
For projects that disturb more than a half-acre, Aldan also requires a bond of at least $10,000 with corporate surety approved by the Borough Solicitor. That’s a meaningful financial requirement that catches a lot of homeowners off guard. The exception to the permit requirement is minor earthmoving for landscaping purposes but the line between “minor” and permit-required is determined by the Zoning Officer, not the homeowner. If you’re unsure whether your project crosses that line, it’s worth asking before you start, not after.
Nationally, residential excavation averages around $3,975, but that number doesn’t reflect what you’re actually dealing with in Aldan and Delaware County. Labor rates in the Philadelphia metro run 15 to 25 percent above rural Pennsylvania averages, and Pennsylvania carries a regional cost multiplier above the national baseline. For most residential projects in Aldan grading, drainage correction, site prep for a retaining wall or patio you’re typically looking at a range that reflects those regional conditions, plus any disposal, compaction, and drainage work built into the scope.
The bigger variable is soil. Aldan’s clay-heavy soil takes more time to excavate, handle, and compact correctly than sandy or loamy conditions. Clay also requires more attention during backfill to avoid future settling. When you’re comparing quotes, pay attention to what’s actually included permits, disposal, drainage planning, compaction because the lowest number often leaves those out. A quote that skips proper compaction or drainage grading might save money upfront and cost significantly more when the patio sinks or the basement floods after a heavy rain.
Most drainage problems in Aldan come down to two things: clay soil and grade shift. The clay-heavy soil that runs through Delaware County drains poorly on its own it holds water, expands when saturated, and compacts over time in ways that change how runoff moves across a lot. Add 60 to 80 years of seasonal freeze-thaw cycles, and the original yard grade that kept water away from the foundation in 1955 may now be directing it straight toward it.
Excavation and regrading can correct this directly. The process involves removing soil to the depth needed, reshaping the terrain so that water flows away from the structure, and compacting the base in layers so it holds that grade over time. In some cases, a French drain or subsurface drainage system is added during the same excavation phase. Aldan’s borough code actually requires that surface areas adjacent to buildings be graded so water drains away from the structure so proper drainage grading isn’t just good practice here, it’s a code requirement. Getting it done right means fewer wet basements, less foundation stress, and a yard that doesn’t pool after every storm.
It affects almost everything. At 0.6 square miles with roughly 1,800 housing units, Aldan is one of the most densely packed boroughs in Delaware County. Lots are small, neighbors are close, and a significant portion of the housing stock includes row houses and attached homes where property lines are tight and drainage systems are sometimes shared. That means equipment selection matters, access routes need to be planned carefully, and every grading decision has to account for where water ends up including on adjacent properties.
Aldan Borough code explicitly prohibits grading that directs surface water onto neighboring properties or creates unstable slopes. In a dense residential setting, that’s not just a legal requirement it’s a practical one. A contractor who doesn’t account for neighboring lot elevations and drainage patterns when planning the grade can create a problem for your neighbor that comes back to you. Working in Aldan’s residential footprint requires precision and familiarity with how these properties sit relative to each other, not just raw excavation capacity.
Spring is the busiest season for excavation and grading in Aldan, and for good reason. Homeowners who dealt with basement flooding or yard drainage problems over the winter want them corrected before the next rainy season hits. Frost heave in clay soils also does visible damage to driveways, walkways, and yard grades over the winter months, which motivates a lot of spring project decisions. The downside is that booking windows fill fast if you’re planning a spring project, reaching out in late winter gives you the best shot at your preferred timeline.
Summer and fall are both solid windows for excavation work. Fall is particularly good for grading and site preparation if you want to be ready to build in the spring the ground is workable, crews are available, and some contractors offer off-season pricing. Winter is the hardest season for excavation in Delaware County. Frozen clay is significantly more difficult and expensive to excavate, and Pennsylvania’s freeze-thaw cycle means ground conditions can change week to week from November through March. Emergency work can still happen in winter, but planned projects are better timed earlier in the year.
We handle the full project and that distinction matters more in Aldan than in a lot of other places. Because lots here are small and the work phases are closely connected, handing off from a dig-only excavation contractor to a second crew for the retaining wall or patio creates real risk. Different crews bring different standards, different equipment, and different assumptions about what the previous phase left them to work with. In a tight residential borough where the excavation, the drainage plan, and the finished surface all have to function together, that gap between trades is where problems start.
We handle excavation, site grading, drainage, retaining walls, patios, and finished outdoor living spaces with one team. The crew that grades your lot is the same crew that builds what goes on top of it. That means the drainage slope is designed with the finished patio in mind from day one, the retaining wall footing is set at the right depth because the same team dug it, and nothing gets lost between phases. For Aldan homeowners who want the project done once and done right, that’s the practical advantage of working with us.
