Downingtown · 19335

What a Downingtown address actually covers

The borough is the old center on the East Branch of the Brandywine. The 19335 ZIP is a good deal larger, covering eight municipalities, and East Caln wraps the borough so closely that you cannot tell on the street where one stops.

Water is what ties the whole area together. The ground here holds moisture longer than it does up on the ridges, and we find wet basements well outside the mapped flood zone. So on any basement job in this ZIP the first question is where the water is getting in. Finishing over a damp wall just puts drywall in front of the problem.

The 8 municipalities in the Downingtown area

Downingtown Borough
The old center, and the only part of the ZIP where floodplain rules come up regularly. Well-kept 1930s twins near the middle, oil-heated Cape Cods off East Lancaster Avenue, and the usual older-house list waiting behind the plaster. If the parcel sits inside a mapped floodplain, a permit is required before any construction at all, interior work included.
East Caln Township
Wraps the eastern half of the borough. On the street you cannot tell where one stops and the other starts. Condominiums through to large single-family homes, plus the Brandywine Square shopping area. Scope varies house to house more than anywhere else in the ZIP.
Caln Township
East along Lancaster Avenue toward Coatesville. Older suburban housing and apartments. Small kitchens, original bathrooms.
East Brandywine Township
North of the borough, built out through the nineties and 2000s on what used to be farmland. A lot of tall unfinished basements sitting under those houses.
West Brandywine Township
More rural again. Bigger lots, more wells and septic, and a longer run between stops.
West Bradford Township
South toward Marshallton. Subdivisions mixed with open ground, and older stone houses scattered through the western end.
Uwchlan Township
Lionville and the Exton edge. Dense by local standards, mostly eighties and later, with townhouses and carriage homes alongside the colonials.
Upper Uwchlan Township
North toward Marsh Creek, and the newest housing in the ZIP. Applecross and the developments around the state park. Big houses, square framing, and basements left bare for whoever bought the place.
Permits

Permits, floodplain rules, and basements around Downingtown

Where your permit comes from
Downingtown Borough Code Enforcement inside borough limits. Addresses in East Caln, Caln, East Brandywine, West Brandywine, West Bradford, Uwchlan, or Upper Uwchlan go to that township, which is most of the housing in the ZIP.
If the parcel sits in a mapped floodplain
The borough requires a permit before any construction or development in an identified floodplain area, and that takes in interior renovations, not just new structures. Surrounding townships have their own ordinances along the same creek. Under those rules the basement counts as the lowest floor and the work has to keep water away from utilities and equipment, which can decide whether a basement gets finished at all.
Most wet basements here are nowhere near the flood zone
They are ordinary hydrostatic pressure coming through the floor-to-wall joint or a crack in a poured wall, made worse by ground that drains slowly. That is a waterproofing job, and it gets priced into a basement finish rather than added on afterward.

Rules and review times change. Confirm the current requirements with Downingtown Borough Code Enforcement, or ask us at the estimate and we will check it for your address.

Reviews from Chester County homeowners

Downingtown remodeling FAQs

Why does my Downingtown basement leak when it rains hard?

Heavy rain saturates the ground faster than it drains and pushes water through the weakest point in the foundation, usually the floor-to-wall joint or a crack in a poured wall. Ground near the East Branch of the Brandywine stays wet longer, which is why it is so common here. The right fix depends on the path the water is taking, so we inspect before pricing.

Can I finish a basement in a Downingtown floodplain?

Sometimes, but the floodplain permit comes first. The borough requires a permit before any construction in an identified floodplain area, interior renovations included, and the basement counts as the lowest floor. Most homes in the ZIP are not in the mapped zone, so we check the flood map before quoting either way.

How much does basement waterproofing cost in Downingtown, PA?

From about $600 for a single foundation crack repair to $8,000 to $18,000 for a full interior drain and sump system with battery backup. Exterior excavation runs $15,000 to $35,000. The inspection and the estimate are free.

Do you remodel the eighties and nineties colonials around Downingtown?

Yes, and they are our most common job here. Good bones, dated finishes: builder cabinets, laminate tops, and a kitchen half-closed off from the family room. Opening it up and replacing cabinetry and counters normally needs no structural work.
