If you live in Northumberland County, PA, you know how unpredictable the weather can be. From heavy summer storms to winter snowmelt, basements in the area often face water intrusion, damp air, and foundation cracks. Older homes with stone or block foundations are especially vulnerable, while newer homes can also experience flooding if drainage systems aren’t properly maintained. Left untreated, these problems can lead to mold and mildew growth, structural damage, and decreased home value. That’s why professional basement waterproofing in Northumberland County is essential for protecting your home, keeping your family safe, and maintaining a healthy indoor environment year-round.

Why Basements Leak in Northumberland County
Basements in Sunbury, Shamokin, and surrounding Northumberland County towns face unique water challenges. In many cases, these issues are caused by a combination of soil conditions, weather patterns, and aging construction. Common causes of basement leaks include:
Hydrostatic pressure: When water builds up in the soil, it pushes against basement walls and floors.
Freeze-thaw cycles: As temperatures rise and fall, expanding and contracting cracks weaken older foundations.
Poor drainage: Gutters and grading that direct water toward the home instead of away from it.
Aging walls: Block or stone foundations commonly found in older Northumberland County homes.
If these problems are left unaddressed, they can lead to basement flooding, mold growth, and even structural damage over time.
Our Permanent Waterproofing System will Keep Your Basement Dry… For Good…
We don’t rely on quick fixes like paints or surface sealants. Instead, we design custom waterproofing systems tailored to your home’s specific conditions. As a result, you get long-term protection—not temporary relief.
Our solutions may include:
First, interior French drains that collect groundwater beneath the slab to prevent pooling and mold
Next, high-capacity sump pumps with optional battery backup to ensure continuous protection
In addition, patented crack repair that permanently seals cracks and prevents them from spreading
When accessible, exterior waterproofing and grading improvements to divert water away from the foundation
Finally, vapor barriers and dehumidification systems for long-term moisture control and healthier indoor air
Because every system is custom-designed, homeowners can enjoy a dry, safe basement year-round.
