Question 1

How do I know if my drainage problem needs professional excavation or just a simple fix?

Accepted Answer

If water pools near your foundation, your basement shows signs of water intrusion, or erosion is actively damaging your landscape, you need professional excavation. Simple fixes like extending a downspout work for minor issues, but persistent drainage problems require regrading, pipe installation, or both.

Question 2

How long does a drainage project take?

Accepted Answer

Most residential drainage projects in Somerset and Hunterdon County take 2 to 5 days of active work. Permitting, if required by your township, can add 1 to 3 weeks. Weather delays are common in spring, especially on clay soil.

Question 3

Will fixing drainage require tearing up my whole yard?

Accepted Answer

Not necessarily. An experienced contractor plans the work to minimize disruption. Trenching for pipe is typically 12 to 24 inches wide. Regrading focuses on specific problem areas. Some lawn restoration is usually needed, but a good contractor restores affected areas as part of the project.

Question 4

Does my township require a permit for drainage work?

Accepted Answer

It depends on the scope. Minor grading and downspout extensions typically don't. Larger projects involving significant excavation, new pipe systems, or changes to stormwater flow patterns usually do. Hillsborough, Bridgewater, Branchburg, and Flemington each have different requirements. Your contractor should handle the permitting process.

Question 5

Can drainage problems cause foundation damage?

Accepted Answer

Yes. Sustained water pressure on foundation walls can cause cracking, bowing, and water infiltration. Over time, this can lead to serious structural issues that are far more expensive to repair than the drainage problem that caused them. Fixing drainage early prevents foundation damage.
