Local Conditions
Why Do Longwood Row House Basements Get Wet?
The areaway is often the culprit. Row houses here have a sunken space between the stoop and the sidewalk, and rain collects in it. If its drain clogs or its floor pitches toward the house, water reaches the basement door and wall. Old foundation walls then let moisture through.
Longwood is an inland area with no flood exposure that we can confirm beyond heavy rain sewer backups. Most basement water here comes from rain, drains and wall condition.
Pre war apartment buildings have deep basements with boilers, laundry and storage. Water there damages equipment and belongings.
Sidewalks on tree lined blocks can pitch toward the building. Water runs along the walk, pools against the wall and works through old mortar joints.
How Do You Stop Areaway Water From Reaching the Basement?
We start with the areaway. We check the floor pitch, the drain and the walls, clear or repair the drain, correct the slope and seal cracks where the areaway meets the house. If water still enters, we add interior drainage or repair the basement wall itself.
A working areaway drain is simple but vital. Leaves and debris clog it, and a clogged drain turns the areaway into a small pool against your wall.
What about a sewer backup?
A sewer backup is a plumbing problem. Only a licensed plumber should handle it, and that plumber may advise a backwater valve. We tell you if water is coming from that source.
Do permits or the historic district apply?
Some basement work needs DOB permits, and LPC approval can apply to visible exterior changes inside the Longwood Historic District. Confirm current rules with the city.

Book an Inspection Call NowHow Can I Keep My Longwood Basement Drier Before Repairs?
Simple habits help while you wait for a repair. Keep the areaway drain clear, point downspouts away from the wall, and lift stored goods off the floor. These steps do not replace waterproofing, but they reduce the water your basement has to handle.
Sweep leaves and trash from the areaway after every storm, and check that the drain runs when you pour a bucket of water over it. A slow drain will fail in a heavy rain.
Look at the sidewalk beside your building. If it tilts toward the wall, tell us, because a sidewalk fix may be part of the answer.
A dehumidifier can keep the air drier, but it only treats the symptom. The wall or drain still needs repair once we find the source.
