Drainage in Mountville, PA

Mountville is a small borough in western Lancaster County, and we reach it from our base in Lancaster. If water sits in your yard, seeps into your basement or runs toward your foundation, we can look at it and tell you what is causing it. This page covers what is particular about drainage in Mountville and how a visit works.

Why drainage in Mountville is shaped by two creek watersheds

Mountville sits on an elevation. That is how it got its first name, Mount Pleasant, when Isaac Rohrer laid out the town in 1814. A rise in the ground sounds like good news for water, and often it is, but it also means the borough sheds water in two directions.

The eastern side drains toward the West Branch of Little Conestoga Creek, which flows south into the Conestoga River. The western side drains toward Strickler Run, which flows west to the Susquehanna. Which side of the borough your lot is on tells you roughly which way surface water wants to travel after a heavy rain. On a sloped lot, that water can run straight at a foundation wall or collect against the uphill side of a house.

The borough is just under one square mile, so lots are close together. Your downspout discharge, your grading and your neighbour's grading all affect each other. A drainage fix has to send water somewhere it will not become someone else's problem, and that matters more on a compact lot than on a large rural one.

Older lots, newer additions and what that means for basements

The original town was divided into building lots in 1814, and the borough has grown by annexation since. Mountville now mixes residential, commercial, industrial and public property. In practice, you can find older houses with stone or block foundations on the same street as much newer construction.

Older foundations tend to show water in a few familiar ways: damp stains low on the wall, white mineral crust called efflorescence, a musty smell after rain, or water coming in where the wall meets the floor slab. Those are signs of water pressure against the foundation, not just a leaky pipe. Newer homes can have the same trouble when the backfill around the foundation has settled and the ground now slopes toward the house.

If you have lived in the house a while and the basement was dry until recently, ask what changed. A downspout that now ends beside the wall, a patio that settled, or a neighbouring lot that was regraded can each be enough.

The drainage services we offer in Mountville

We install and repair drainage on three main lines of work, and each one is a different answer to a different problem.

French drains and subsurface drainage

When groundwater or soggy soil is the problem, a trench filled with washed stone and a perforated pipe carries water away underground. This is the core of French drain installation, and it also covers curtain drains, foundation drains, interior drains and dry wells. The right type depends on where the water comes from and where it can safely go.

Wet basements and sump systems

When water is already inside, the work is different. Basement waterproofing covers wet basement repair, sump pump installation and replacement, foundation crack repair and crawl space waterproofing. The aim is to collect the water that reaches the foundation and move it out, rather than patching the wall and hoping.

Surface water in the yard

When the trouble is standing water, erosion or runoff across the lot, yard drainage is the starting point. That includes regrading, downspout drainage, catch basins, channel drains, swales, erosion control, culverts and commercial drainage. Often a basement problem is really a surface-water problem that has been ignored, and fixing the grade and the downspouts is the cheapest repair.

What a drainage visit in Mountville involves

We are based in Lancaster and travel to Mountville for visits. We do not have an office in the borough. Route 462 runs through the middle of town as Columbia Avenue, and US 30 passes along the north side, so getting there is straightforward.

A visit starts outside. We walk the lot and look at the grading, the gutters and where each downspout ends. We look at the foundation for cracks, staining and soft ground along the walls. If there is a basement or crawl space, we go inside and look at the floor, the wall-to-floor joint, any existing sump pit and any signs of past water.

Then we talk through what we found. You get a plain explanation of where the water is coming from, which fix suits it, and whether a smaller repair would do the job. If a French drain, a sump pump or some regrading is the right answer, we say so and explain why. If the problem is simple, such as a downspout that needs to be extended, we tell you that too.

Why a drainage fix has to suit the soil and the site

Water moves differently depending on what it moves through. Heavy clay holds water and drains slowly, so a trench needs a steady fall and a clear outlet. Looser soil drains faster but can wash out around a downspout. A drain pipe is only as good as its outlet, which is why we always work out where the water will end up before we dig.

In a borough with creeks on both sides, the outlet is often the hard part. Daylighting a pipe onto sloped ground, tying into a swale or sending water to a dry well each have limits, and some lots cannot use all of them. We pick the method that fits your lot instead of repeating the same install everywhere.

Mountville has a lot of public park space for its size, and many residents notice how much open ground there is around the borough. That is useful context for a yard that slopes toward a green area, but it does not mean you can send water onto land that is not yours.
