The short version
- The 19342 ZIP is 62% Concord Township, then Thornbury (17%), Chester Heights (8%), Edgmont (5%), and Middletown and Chadds Ford (4% each). A small piece reaches into Chester County; this page covers the Delaware County, PA side.
- Concord Township's resale certification takes about 3 to 4 weeks and needs notarized affidavits for house numbers and for smoke and carbon monoxide alarms, plus a sewer or septic report.
- Concord inspects the outside only, but sidewalk, curb and driveway apron repairs in the public right-of-way must be done before settlement.
- Selling in an HOA or condo? The association must give you a resale certificate within 10 days of your request, and the buyer can back out until 5 days after getting it.
- We buy as-is for cash. If your house is updated and would sell well with an agent, we will tell you.
Where exactly is Glen Mills?
Glen Mills is a post office name, and the 19342 ZIP stretches across six townships and boroughs. Concord Township, the biggest piece, also includes the village of Concordville (which has its own P.O. box ZIP, 19331), and parts of Concord get Garnet Valley, Chadds Ford or Thornton addresses instead.
| Township or borough | Share of 19342 | Good to know |

| Thornbury Township | 17% | Also served by the Thornton and Cheyney post offices |
| Chester Heights Borough | 8% | Has a P.O. box ZIP of its own, 19017 |

The township or borough on your tax bill, not the Glen Mills address, decides which resale rules you follow.
What kind of homes are in Glen Mills?
Newer than most of Delco. Subdivisions of single homes, townhomes and carriage homes, many inside homeowners associations, sit beside older farmhouses, stone homes and houses on large lots, some still on septic systems.
What we see needing work: original roofs, windows, heating and air systems and water heaters reaching the end of their life in homes from the 1980s through the 2000s; stucco that has trapped moisture in some homes from that era; tired decks; finished basements with water problems; and septic systems, or a required hookup to public sewer at resale in Concord.
What does Concord Township require before you sell?
A resale certification. Concord's code office says use and occupancy inspections happen at every change of ownership, and its 2026 resale instructions list six forms:
- Resale certification application. Typed or printed in ink.
- Sewer or septic report. A short questionnaire about your sewer connection, sump pumps, downspouts and cleanouts. A house on its own septic system within 150 feet of a township sewer line must connect to public sewer before the resale certificate is issued.
- House number affidavit, notarized. Numbers on both sides of the mailbox or post, at least 36 inches above the ground, at least 4 inches tall, in a contrasting color. Mistakes mean a $100 re-inspection.
- Smoke and CO alarm affidavit, notarized. A smoke detector on every level and in every bedroom, and a carbon monoxide alarm on every level.
- In-ground pool affidavit, notarized. Even if you only check "no pool."
- Sewer certification ($20). For homes on township sewer, it shows the sewer fees due at settlement.
The township itself inspects only the outside. Sidewalks, curbing and driveway aprons in the public right-of-way must be in good condition, and the instructions say all needed repairs must be done before settlement. The 2026 fee schedule lists residential resale certification at $100 (on-site) or $200 (sewer, paid as two $100 checks).
Plan for 3 to 4 weeks. Concord wants original notarized forms, not copies, printed single-sided. If your curb or apron needs work, tell your buyer early, because it has to be fixed before closing.
What about Thornbury, Chester Heights and the rest of 19342?
Chester Heights handles sales through a use and occupancy inspection. Its application, revised in March 2026, asks for the buyer and the settlement date and lists a $120 fee. Middletown requires a sewer certificate from its sewer authority before a sale, including a camera inspection of your sewer line ($200; allow at least two weeks). For Thornbury, Edgmont and Chadds Ford, call the township office before you set a closing date and ask whether it requires a resale inspection or sewer certification.
Selling a house in an HOA or condo
Pennsylvania's planned community law (for HOAs) and its condominium law say the same thing about resales. Before the buyer signs, or at least before closing, you have to give them the declaration, bylaws, rules and a resale certificate from the association. That certificate shows:
- The monthly assessment and any unpaid dues or special assessments.
- Other fees, planned capital projects and the reserve fund.
- The budget, insurance, and any lawsuits against the association.
- Whether the board knows of violations on your unit.
The association has 10 days from your request to provide it. The buyer can cancel the contract until the certificate arrives and for 5 days after, or until closing, whichever comes first, and the buyer is not liable for unpaid dues beyond what the certificate shows. Ask for it the day you decide to sell. The rule covers resales by owners, including a cash sale to us.
Where do probate and sheriff sales happen?
In Media, at the county Government Center, 201 W. Front St. The Register of Wills handles probate there, and sheriff sales are held on the third Friday of each month at 11 a.m. See our Delaware County, PA page for details.
Why do Glen Mills owners sell to a cash buyer?
- A job move or a second mortgage payment once you have already bought the next house.
- An estate, where the heirs live elsewhere and nobody wants to manage a sale from a distance. Our inherited house guide is written for Philadelphia, but most Pennsylvania steps apply here too.
- A divorce, where both sides want a firm price and a set date.
- A house that needs updating, like a 1990s kitchen, stucco repairs or a failing septic system. See how selling as-is works.
- A townhome you have been renting out. Read about selling with tenants.
The honest part: many Glen Mills houses are in good shape and would bring more listed with an agent. If that is your house, we will say so.

Glen Mills questions
Is Glen Mills in Delaware County, PA, or Chester County?

How long does Concord Township's resale certification take?
The township says about 3 to 4 weeks. It needs original notarized affidavits, and any sidewalk, curb or driveway apron repairs in the right-of-way must be finished before settlement.
Do I need the HOA resale certificate if I sell to a cash buyer?
Yes. Pennsylvania's planned community and condominium laws cover resales by owners, whether the buyer pays cash or uses a loan. The association must provide the certificate within 10 days of your request.
My Concord house is on septic. Do I have to connect to public sewer to sell?
If the house is within 150 feet of a township sewer line, yes. Concord's resale instructions say it must connect before the resale certificate is issued. Otherwise, the sewer or septic report asks whether a septic inspection was done and how it came out.
