Ilchester sits directly across the Patapsco from us, close enough that we are usually there faster than our stated window. It is a genuinely beautiful place to live and a slightly awkward place to plumb, because the terrain does not do flat.
Steep grades mean drainage runs at unusual angles, storm water moves fast through properties, and where a house sits on the slope determines almost everything about how it handles water. Two houses on the same street can have completely different basement stories.
The housing runs from older properties near the valley to newer development up on the higher ground. We ask about both the build year and the position on the slope before quoting, because either one on its own is only half the picture.
What we find in Ilchester homes

Steep terrain and fast runoff
Storm water moves quickly downhill through properties here rather than soaking in. Where a house sits relative to its neighbours determines how much water arrives at the foundation, and it varies dramatically over short distances.
Valley-adjacent groundwater
Properties on the lower ground toward the Patapsco deal with persistent groundwater rather than occasional storm water. Sump systems there are working appliances and wear accordingly.
Mixed build eras
Older valley properties alongside newer hillside development. The same symptom points at different causes depending on the era, so we establish it before quoting.

What Ilchester customers tell us
Ilchester is close enough that our customers there tend to become long-term ones. Proximity earns a lot of goodwill when something goes wrong at midnight.
I had an outstanding experience with Collins & Sons LLC. Daniel has done several projects at my home over the last 4 years. He has helped me with small projects (replacing a garbage disposal), large projects (renovating my patio) and random projects. No mat…

Danny is a very professional and friendly person to work with. His work as a plumber and contractor is outstanding. He receives a high rating as he cleans up after he finishes working. I highly recommend this company and Danny to work on any project for you…
Plumbing questions from Ilchester
How quickly can you get to Ilchester?
Quickly — it is about six miles from our Westowne Road shop, straight across the valley. Same-day is usually workable for non-emergency work and emergencies get a real ETA on the phone.
My neighbour has no basement water and I do. Why?
On terrain this steep, position on the slope matters more than construction. Water moves downhill through the soil and arrives at whichever foundation is in its path. It is not unusual for adjacent properties to have completely different experiences.
Do I need a battery backup sump pump here?
On the lower ground toward the valley, if your basement is finished, yes. The storms that fill the pit are the same storms that take the power out — that is cause and effect rather than coincidence.
