In-house excavation crew grading a Frazer PA property for a new pool build
Every project we build depends on the site work under it. A pool sitting on a shell that was excavated to the wrong depth is a problem forever. A retaining wall built on unstable fill starts moving in year two. A patio built on ungraded soil holds water and heaves through the first winter. That's why we don't hire this out. For 18+ years our excavation crew has been in-house — the same crew that handles storm-water infiltration, grading, and drainage across every one of our projects in Frazer, Chester County, and the Main Line. ## What we do - **Pool excavation** — sized precisely to the pool shell design, cleaned to a proper subgrade - **Grading** — final grade of the whole yard, keyed to the storm-water plan - **Storm-water infiltration basins** — engineered surface or underground basins that meet Chester County requirements - **Drainage** — French drains, dry wells, catch basins, and yard drains tied into daylighted outlets - **Downspout and roof water management** — extending and burying downspouts, tying into drainage systems - **Grade corrections** — fixing existing properties where the grade was never set right - **Site prep for structures** — pads for [pavilions](/services/pavilions/), [pool houses](/services/pool-houses/), and outbuildings - **Trenching** — utility trenches for pool equipment, [landscape lighting](/services/landscape-lighting/), irrigation ## Chester County storm-water requirements Most Chester County and Delaware County municipalities now require some form of engineered storm-water management for new pools, additions, and significant hardscape projects. That means: - An engineered site plan showing the proposed impervious coverage - An infiltration basin sized to hold and infiltrate the difference - Inspections during construction - A recorded operations-and-maintenance plan for the basin We build this into every applicable project as a matter of course — engineering, permitting, construction, and final inspection. ## Why in-house matters Every project we've ever seen go sideways started with a scheduling gap between the excavator and the next trade. Excavator finishes on Friday. Weather rolls in over the weekend. By Monday, the hole is full of water, the site is a mud pit, and the next crew won't touch it. Delay compounds. When excavation is us, that gap doesn't exist. We finish the excavation and the next phase is already on site the same afternoon. ## Built with the whole project Excavation happens first on every project. It sets the pad for the [pool](/services/inground-pools/), the [patio](/services/patios-walkways/), the [pavilion](/services/pavilions/), and every [retaining wall](/services/retaining-walls/). It also runs the trenches that later carry pool plumbing, [lighting](/services/landscape-lighting/), and irrigation to the [planting beds](/services/landscape-design/). ## Serving your neighborhood We excavate and grade across Frazer, Malvern, Chester Springs, Downingtown, West Chester, Wayne, Bryn Mawr, Villanova, Gladwyne, Bala Cynwyd, Media, Chadds Ford, Newtown Square, and the surrounding Main Line and Chester County neighborhoods — always as part of one of our design-and-build projects.

Frequently asked questions

Why is having in-house excavation such a big deal?
Because when your pool builder or landscape contractor has to hire an outside excavator, the whole project schedule depends on that outside crew's availability. When we own the excavation, we set our own schedule, and we own the outcome. If the grade is wrong, there's no one to point at except us — and we fix it.
What is a storm-water infiltration basin?
It's an engineered underground or surface basin that captures storm water from your property and lets it slowly infiltrate the soil instead of running onto neighbors or into public storm drains. Most Chester County municipalities now require them for new pools, additions, and significant hardscape projects.
Do you handle drainage on existing properties with water problems?
Yes — grading corrections, French drains, dry wells, downspout extensions, and yard drainage systems. Many drainage problems come from grade that was never set correctly in the first place; we fix the underlying issue instead of just adding drains.
Can you excavate for pools, additions, and driveways?
Pools yes — as part of our pool builds. Additions and driveways as needed on projects where we're the general scope. We're not a standalone excavation contractor for random third-party jobs.
