Common Causes of your Basement Problems in New Haven

Foundation Cracks

Cracks in foundation walls or floors can let water seep into your basement, especially during heavy rain.

Poor Drainage Systems

Ineffective drainage, such as clogged gutters, downspouts, or poorly graded yards, directs water toward your foundation.

Hydrostatic Pressure

Water in the soil builds pressure against basement walls, filling the clay bowl, and forcing water through cracks and joints.

High Water Table

Rising groundwater during heavy rain or snowmelt can seep into your basement through cracks or porous concrete.

Faulty or Missing Sump Pump

Water from heavy rainfall or flooding can accumulate in your basement without a working sump pump.

Plumbing Leaks

Leaking pipes or fixtures near your foundation can saturate the soil, causing water to seep into your basement and cause moisture related problems.
