Most calls from Andover homeowners come down to a handful of problems: a sump pump that can't keep up, seepage at the base of the wall, cracked block, or damp air. Here's what's common locally and what it costs.
About basements in Andover
Andover has large lots, mostly newer construction and plenty of wetlands. A high spring water table is the main pressure on basements here, so pump capacity and a backup matter.
Common problems in newer homes
- A sump pump that runs every few minutes from March through May
- Settling cracks in poured walls
- Builder-grade pumps that fail during storms or power outages
- Damp, humid air in an unfinished basement
In newer homes the fix is usually about capacity and reliability: a stronger pump, a battery backup, sealed cracks and good humidity control. Drain tile upgrades come in when water still reaches the floor.

Questions from Andover homeowners
How much does it cost to waterproof a basement in Andover?
Many Andover homeowners spend somewhere between $2,000 and $11,000. A new pump, backup or crack repair costs less; a full drain tile system costs more. The contractor prices it after seeing the basement.
My sump pump runs all spring. Is that normal in Andover?
In high water table areas it often is. Constant running wears pumps out faster, so a quality pump and a backup are worth it.
Does Andover require a permit?
Structural repairs, and sometimes changes to where your sump discharges, may need a permit from the City of Andover. Your contractor should handle it.
Is the estimate free in Andover?
Yes. Our referral service is free, and the contractors we work with give free estimates.
