Do You Have Any of These Basement Problems?
White Chalky Residue on Walls
Chalky white stains mean water is pushing through your walls from outside. Small today, major leak tomorrow.
Cracks in Walls or Floors
Every crack is a path for water. Cracks only get worse with every heavy rain and every freeze.
Visible Water or Puddles
Standing water means your waterproofing has failed. Mold follows within 24 to 48 hours.
Basement water problems never fix themselves. They get worse with every spring storm and every heavy rain. A $2,000 fix today can turn into a $20,000 mold job next year. Caught early, most water problems are fixable quickly and for good.

Jermaine and his crew completely waterproofed my basement after bad flooding. Water was even coming through the walls. They installed a second sump pump, a second dehumidifier, and a French drain. I've had lots of heavy rain since and not a sign of any flooding.

We hired Jeffries to investigate a persistent leak into our basement. The team exposed the source from the outside, repaired it, and even handled some mold inside. These guys work hard and do it all. They will be my go to guys in the future.
Verified Google Review
We hired Jeffries to install a French drain and sump pump in our nearly 200 year old stone foundation basement. The price was very reasonable. They completed the job as promised and were flexible moving up the schedule for us.
