📞 +1-866-476-1348Most New London customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
Odor is often the first sign New London customers notice, well before any visible water shows up.
Stair-step cracks in block foundations are a common early warning sign we see across New London-area homes.
Efflorescence is a clear sign that water is actively passing through your New London foundation wall, even if you've never seen standing water.
A pump under constant strain tends to fail at the worst possible time — usually during the next big New London storm.

Storm season in New London, MN means our emergency line gets busy fast — we triage calls by severity so active flooding at your New London address jumps the queue ahead of routine inspections.
Call for Emergency Service →Hairline cracks are how most New London basements start leaking. We use epoxy injection to seal the crack from the inside out, stopping the leak at the source instead of just painting over the symptom.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your New London lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →An interior drain tile system channels water to a sump pump before it ever reaches your New London basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →Older New London homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
Get a Crawl Space Quote →We can phase larger New London commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.

Once the repair is done, you get documentation of the work and a written warranty — not just a handshake.
We quote the job in writing after inspecting it in person, so what you agree to on the phone or at your door is what shows up on the final invoice.
Our trucks stage locally around New London, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
If a covered repair fails, we come back and make it right. That's written into every contract, not just promised on the phone.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
