Transparent Pricing

Transparent Pricing & Site Requirements

We provide honest, upfront estimates. While we can often give a rough budget over the phone, a final quote requires a site evaluation. Here is what impacts the cost of your project:

Terrain Slope

Is the yard perfectly flat or severely off-level? Steep slope adds grading labor.

Site Access

Can our compact equipment reach the spot easily, or is access tight and restricted?

Hidden Obstacles

Underground utilities, rock formations, or tree roots that must be navigated around.

Size & Shape

Larger areas, L-shapes, or custom dimensions require more material and labor time.

Site Clearing Required

Trees, stumps, or debris that need removal before the area can be prepared.

Material Upgrades

Premium materials, decorative edging, or enhanced drainage add material cost.

Customer Reviews

What Clients Say About Our Excavation Services In Wilmington, DE

Luke WitterSite Prep did a very good job on my new septic system. They were very helpful in helping me decide what system to install, and very responsive to any questions I had. Gid did a great job in sales walking me through the process from start to finish. Ivan was very knowledgeable on the designs and staking out the land and keeping the SEO informed with our progress. And both Ben’s did great work with the installation of the system. They made excellent time and were very professional. Pricing was very competitive even though I was pretty far from their home base. I was impressed. I would recommend working with Site Prep on any excavation needs you may have. Thanks to everyone involved!Read moreWillie De LunaI was called a week prior to set up my appointment for my Shed pad to be installed by this company. They gave me an appointment of 7 AM and I was so impressed that they arrived on time to the minute! I met Samuel and Roman, who were too young men who impressed me tremendously. They explained to me the entire procedure and how long it would take to complete. They were very skilled and professional. It was good to see two young men demonstrate such great work ethics and responsibility! That is rarely seen by young people today. I could not speak more highly of this company and the two young men that came out to perform the work for me today. Both young men took care that my property was not damaged by their heavy equipment or the work they performed. They cleaned up after themselves prior to leaving and went over the final results with me. I would highly recommend this company for any excavating work to be done. I am one that is rarely impressed and usually disappointed by contractors. They did not disappoint and met all my expectations to the fullest.. Great job I commend you all!Read moreChip Hower5 Stars — Outstanding Work! AJ and James from Site Prep did a wonderful job creating the pad for my new garage. They worked single-handedly, worked exceptionally well together, and delivered top-notch results from start to finish. I highly recommend Site Prep for any excavation or pad preparation Thank You Both!Read moreDustinWe got a gravel shed pad installed by Site Prep for our new shed we had built. Communication with the employees at Site Prep leading up to the day it was installed was very professional and everyone was very helpful. AJ and James went above and beyond excavating, grading, and building out the gravel pad. Really pleased with the work, quality, and attention to detail both these guys did! Will definitely refer them to anyone that needs their skills and will use them again in the future for any big projects like this. Thanks!Read morePamela RosenthalStephen was very personable and took the time to stake out 2 variations and share the benefits of each. He and Melvin created a secure base for our upcoming shed. The foundation looks great and the surrounding wood appears perfectly aligned. After digging / creating the site space, they left no traces of extra dirt and I would recommend them without hesitation.Read moreLinda WilsonBoth gentlemen worked their buts off digging, preparing and stoning the area for out garage and got the job done perfectly!Read moreK WI can’t recommend this company highly enough! They prepared our site for a building, which included excavation, building a retaining wall, gravel pad, and finished grading. AJ & Dave arrived right on schedule, and wasted no time getting started. They were fast, friendly, knowledgeable, conscious of my property, and very thorough. It’s quite evident that they take pride in their work, and it really shows! I wouldn’t hesitate to use them again for any future needs!Read moreMitras IndiaBen and James behaved like true professionals. They sent an early notification ahead of their arrival. They discussed the location of the pad with us and let us verify the final boundary markings before they started digging. They cleaned up properly so everything was neat when they left. They took interest in the work. We are happy with the outcome.Read moreJoe JacksonPremium work, excellent customer service, job scheduled & finished quickly. During my 40 years of home ownership I've had a number sheds built/rolled in and I learned early on that a solid pad that deals with moisture is key to a healthy structure. So these days I *always* have a level, chip stone foundation with proper attention to water drainage installed before putting up a shed. I've used different companies. My shed manufacturer recommended Site Prep. Bottom line is: they were terrific, and they were about HALF the cost of the landscape/hardscape companies I've used in the past. Jesus did a visit before to talk to me, get precise location, determine the election & stake out the corners of the pad. He was super knowledgable and gave me good advice. The excavation was a little tricky because some irrigation lines went under the site. He understood that and they took care to not excavate down far enough to cut the lines. The team showed up around 7:30 AM and by 9 AM they were done, and the pad is perfect and ready for the structure. I give them my HIGHEST recommendation.Read moreSam HayesThe Site Prep "experience" was fantastic in every way. Liz did a very through site survey. Sam was the project manager/scheduler and worked hard to accommodate our schedule requirements. Ben was the project foreman. AJ and Dave were total pros and was focused on installing the pad exactly the way we envisioned it (location/orientation/etc). They checked back several times during the excavation and construction process to make sure they were executing to our satisfaction. AJ and Save worked meticulously and expertly to ensure the pad was level and the retaining wall was constructed properly and looked nice. The crew minimized the impact of the equipment and materials on the yard and they cleaned up after the pad was complete. They even filled in a few ruts that were unavoidable. The pad was excavated and installed in just a few hours. You can't go wrong with SITE PREP.Read moreMichael JensenGreat job on the site prep and they also dug a little ditch for me to put a drain pipeRead moreMaryAnnWOW, Jay, Jesus & Steven were fantastic!! They made the foundation and prepared the site for our new 12 x 18 wooden shed. They did an outstanding job and we couldn’t ask for anything more. They dug out the area, leveled it, installed wooden barrier, used rebar spikes to secure everything, layed down a weed barrier, and then filled the area with clean stone. LOOKS PERFECT!!Read more

Excavation

About Our Excavation Services In Wilmington, DE

Excavation is where a project either gets stable or starts collecting future problems. Bad drainage. Soft subgrade. Settlement under a pad. Water pushing toward a basement wall instead of away from it. None of that is dramatic on day one. Later, it is. In Wilmington, that risk is not theoretical - the city’s own resilience work puts stormwater and flood exposure near the center of local infrastructure planning, which is exactly why grade, runoff direction, and site prep cannot be treated as minor details.

If you need excavation services in Wilmington, DE, the job is not just cutting soil and hauling it off. The site has to be read correctly first. Then shaped. Then compacted. Then left ready for the next trade without a mess or a questionable base. That is the part people tend to skip over. It is also the part that decides whether the rest of the build behaves.

Our Excavation Services in Wilmington, DE

Our excavation services are built around ground preparation that supports what comes next. Not around broad claims. Not around vague “site solutions.” The work is usually practical. Get the elevation right. Remove unstable material. Cut utility trenches where they belong. Build a base that will not shift once load or weather starts testing it.

A lot of projects are not neatly separated, either. One property may need grading and trenching in the same pass. Another may need demolition first, then excavation, then final prep for artificial grass installation. That overlap is normal. The mistake is pretending it is not.

  • Foundation excavation and Site Prep
  • Grading and drainage correction
  • Utility trenching and route preparation
    Stone pad and shed pad preparation
  • Concrete and surface removal
  • Base prep for artificial grass installation

That list is broad on purpose. Real properties do not care how categories are named in a proposal. They respond to slope, moisture, compaction, access, and load. A competent excavation company should be able to work through those variables without turning a straightforward job into three separate contracts and a scheduling problem.

Our Excavation and Site Prep Process in Allentown, PA

residential excavation

1. Review the site

We look at grade, drainage flow, access, structures, and the work zone.

2. Plan the work

We define the scope, prep the site, and account for the next phase.

3. Perform the excavation

We dig, trench, shape, remove material, and compact where needed.

4. Clean up and hand off

We leave the area ready for concrete, turf, foundation work, or final build-out.

Residential Excavation Services in Wilmington, DE

Residential excavation usually starts with one visible symptom and one hidden cause. Water near the foundation. A soft edge near a driveway. A pad that never quite stays level. A backyard improvement that cannot move forward until the grade is corrected. Homeowners are not looking for theory. They want the site to function after the work is done - and keep functioning after a season of rain.

Commercial Excavation Services in Wilmington, DE

commercial excavation

Commercial work leaves less room for improvisation. Tighter sequencing. More stakeholders. Less patience for delays. An excavation contractor on a commercial site has to understand access, staging, haul-off, subgrade readiness, and handoff requirements before the first cut begins. Otherwise the excavation is finished only on paper.

Your Local Excavation Contractor in Wilmington, DE

IIf someone is searching for an excavation contractor in Wilmington, DE, what they usually want is not a grand pitch. They want control over the variables that tend to go wrong - drainage, settlement, access, cleanup, schedule drift. Fair. That is how excavation should be evaluated.

When hiring an excavation contractor in Wilmington, DE, the main concern is not the excavation itself but the condition of the site after the work is complete. Grade has to be correct. Drainage has to work. The subgrade has to be stable enough for the next trade. That is what separates routine digging from proper site preparation.

Striving for excellence

Why Choose Site Prep as Your Local Excavation Company

Experience that translates to prep quality

10+ years in shed building and 25+ years in concrete work support better base decisions.

Controlled equipment use

Smaller skid loaders are used when possible to limit damage to lawns, access lanes, and edges.

Accountability after the install

If a stone pad or foundation issue appears, we return and address the problem.

Clear field communication

Crews listen, explain the scope, and work respectfully on occupied properties.

Responsive scheduling

Calls are returned within 24 hours, and many projects finish in about 2 - 4 weeks.

Less coordination burden on the client

One team handles the groundwork instead of passing details between trades.

The case for Site Prep is not built on slogans. It is built on work habits. A site crew either protects the property, communicates clearly, and leaves a stable result - or it does not. That tends to matter more than anything said in a headline.

That combination matters because excavation sits upstream from everything else. When the groundwork is wrong, the next phase inherits the defect. When the groundwork is right, nobody notices - which, honestly, is usually a good sign.

Site Prep - Trusted Excavation Services in Wilmington, DE

Site Prep works in the part of construction most people never see once the project is finished. Subgrade prep. Trenching. Drainage correction. Base work for slabs, pads, turf, and foundations. Sometimes the issue is obvious - a new structure, a failing pad, a drainage problem near the house. Sometimes it is less obvious. A yard stays wet for no clear reason. A low area keeps collecting runoff. The finished surface looks wrong, but the real problem sits underneath.

That is why a local excavation company matters. Wilmington sites are not uniform. Soil conditions across Delaware can swing from heavier, slower-draining clay soils to sandier material with faster infiltration, and compaction changes the way water and air move through the ground. Over-compact the wrong layer or ignore drainage behavior and the site may look finished while the actual problem remains in place.

Service Area for Excavation Services Around Wilmington, DE

Site Prep serves Wilmington and nearby communities across the surrounding service area, including Newark, Bear, New Castle, Hockessin, and Middletown. If your project falls just outside that zone, it still makes sense to contact us. Scope, access, and schedule usually matter more than a line on a map.
