Sump pumps & drainage in Trenton, NJ

The best way to keep water out of a basement is to never let it reach the foundation. We install and replace sump pumps, add battery backups for storm outages, and fix the drainage that carries water away from the house.

Manage the water first

Keep it away from the foundation.

Most foundation trouble around Trenton comes back to water. It pools against the house, soaks the soil, and pushes on the walls and floor until it finds a way in. A good sump pump and honest drainage take that pressure off before it ever becomes a crack or a flood.

We handle both ends of it. Inside, we install and replace sump pumps and add battery backups so the system keeps working when a storm takes the power out. Outside, we fix the grading, extend the downspouts, and add yard drains so the water heads away from the house instead of toward it.

Sump & drainage questions

How often should a sump pump be replaced?
Most sump pumps last several years of regular use, and the harder they run the sooner they wear out. If yours is old, runs constantly, or has failed once already, it's worth replacing before the next big storm rather than after. We'll test what you have and tell you honestly where it stands.
Is a battery backup sump pump worth it?
For most Trenton-area basements, yes. The storms that dump the most water are the same ones that knock the power out, which is exactly when a plain pump quits. A battery backup keeps pumping through an outage, and that's often the difference between a dry basement and a flooded one.
Do I need interior drainage or yard drainage?
Often both play a part. Interior drainage and a sump handle water that reaches the basement; exterior drainage — regrading, downspout extensions, and yard drains — keeps water from ever reaching the foundation. We look at where your water starts and fix it there.
Is the work guaranteed?
Yes. Sump and drainage work is backed by a written warranty, and we go over the terms with your estimate.
