Rowhomes Are Not Just Small Houses
A Baltimore rowhouse is a different animal from a suburban colonial, and its gutters are different too. The front gutter is short — sometimes just twenty feet — but it takes the whole front roof slope. The rear is where the action is: rear gutters, often with downspouts shared or awkwardly routed between neighbors, draining to alleys or rear yards with nowhere good for the water to go. Party walls mean your gutter decisions touch your neighbor's house. And plenty of Baltimore rowhomes — especially the older ones in Fells Point, Canton, and Federal Hill — have built-in box gutters hidden in the cornice, a whole separate system from the hanging gutters most companies know.
We work on rowhomes every week. We know the quirks, the access puzzles, and the neighbor diplomacy. This page is the playbook.
The Rear Gutter Problem
On most rowhomes, the rear gutter does more work than the front — the rear roof slope is often bigger, and the rear faces the trees in the alley or the yard. But the rear is also harder to reach, harder to see from the street, and easier to ignore. We find the worst neglect on rear gutters: years of compost, downspouts disconnected and draining against the foundation, gutters pitched the wrong way for a decade. If you have never actually looked at your rear gutter, you are not alone — but you should. That is where Baltimore rowhouse water damage starts.
How It Works: Our Rowhome Process
Step 1 — Free visit, front and rear. We look at both gutter runs, the downspout routing, the party-wall flashing, and the alley or yard drainage. Every project is different — contact us for a free written estimate.
Step 2 — Written estimate. Itemized by front and rear so you can see exactly what goes where.
Step 3 — Neighbor check. If the work touches a shared downspout or party wall, we will flag it so you can give the neighbor a heads-up. We have done this conversation a hundred times and can help you phrase it.
Step 4 — The work. Most rowhouse jobs take a day. Tight alleys, careful ladder placement, and full cleanup — your neighbor's yard included.
Shared Downspouts and Party Walls
On many blocks, two houses share a downspout at the party wall, or one home's downspout drains across the neighbor's rear. When that shared downspout clogs or breaks, whose problem is it? Practically speaking, it is both of yours — water does not respect property lines. We can often fix the shared section in a way that serves both houses, and splitting the cost with the neighbor is common. We will document what is shared and what is yours so the conversation is easy.
Guards on a Rowhouse: Worth It?
Usually yes, with one caveat. Rowhouse gutters are short, so guard installs are quick and affordable — some of the best value we offer. The caveat is access: if your rear gutter is only reachable through the neighbor's yard or a tight alley, even the occasional guard check is a hassle, which actually makes guards more valuable, not less. Fewer visits needed, fewer access headaches. Our guard installation page has the full story.
Flat Roofs and Built-In Box Gutters
Some older Baltimore rowhomes have flat or low-slope rear sections and built-in box gutters — wooden troughs lined with metal, hidden in the cornice. These are a specialty item: they rot from the inside, they are invisible from the ground, and most gutter companies will not touch them. We evaluate them honestly. Sometimes they can be relined; sometimes the right move is converting to a conventional hanging gutter. Either way, you need someone who has seen them before — we have.
Water Has Nowhere to Go: The Alley Drainage Puzzle
The rowhouse drainage puzzle is the rear: the downspout comes down, and then what? Alleys, tiny yards, concrete pads — nowhere for water to soak in. We route extensions to the best available exit, add splash blocks or short buried runs where they make sense, and make sure your water is not becoming your neighbor's basement problem (or vice versa). See our basement drainage guide for the full picture.
