Yes. A perimeter drain is built to collect water around the foundation and move it away before it keeps saturating the soil against basement walls.
If water repeatedly gathers around the same side of the house, the bigger question is whether the problem is coming from surface runoff, groundwater, or both.
How do I know if water around my basement needs a perimeter drain?
Look for consistently wet soil near the foundation, water appearing along basement walls, damp areas after storms, or puddles that keep forming beside the house.
If the same problem returns every time it rains, the water needs a reliable path away from the foundation rather than another temporary fix.
Is a perimeter drain different from a French drain?
Yes. A French drain usually redirects water from a wet section of the yard or another problem area.
A perimeter drain focuses specifically on water around the foundation. The two systems work on the same basic idea, but where they are installed and what they are protecting are different.
Should the drain go inside or outside the foundation?
That depends on where the water is coming from.
If water is building up in the soil outside the house, exterior drainage addresses the problem before it reaches the basement wall. Interior systems deal with water after it has already reached the foundation area, so understanding the source matters before choosing a system.
Will a perimeter drain solve every basement water problem?
No. If gutters are dumping water beside the house, the grade slopes toward the foundation, or runoff is pouring down from higher ground, those issues may also need to be corrected.
A perimeter drain works best as part of a drainage plan that deals with the actual path the water is taking.
Can a perimeter drain be added to an existing home?
Yes. Perimeter drainage can be installed around an existing house, although the work usually involves excavation near the foundation.
On properties in White Plains and other parts of Westchester County, access, landscaping, patios, walkways, and existing masonry can all affect how the work is approached.
Should I fix the drainage before repairing basement walls?
Usually, yes.
Repairing cracks, finishes, or damaged areas without controlling the water outside can leave the original problem in place. The drainage issue should be addressed first so the repair is not fighting the same moisture again.
Do I need another drainage system along with a perimeter drain?
Sometimes. A perimeter drain may protect the foundation while a curtain drain intercepts water farther uphill or a dry well handles collected runoff.
Larger properties often need more than one step because water can be coming from several directions at once.
Who should I call if water keeps collecting around my basement?
A drainage contractor should look at the grade, runoff, soil conditions, foundation area, and where the water can safely be redirected.
F. La Rocca & Sons installs perimeter drains, French drains, curtain drains, and dry wells throughout Westchester County and surrounding areas. If water keeps collecting around the basement, the next step is figuring out where it is coming from and stopping it before it reaches the foundation.
