What are you seeing?
A symptom points to where water or stress concentrates. An on-site diagnostic assessment confirms the root cause and permanent fix.
Water on the floor
Pools or wet tracking along the cove joint floor seam after heavy rain or snowmelt.
Wet or stained walls
Damp patches, powdery white efflorescence mineral salts, or peeling masonry paint.
Musty odor & damp
Persistent humidity, mold concerns, or heavy air without standing water pools.
Foundation cracks
Stair-step cracks in cinderblock walls, leaking concrete fissures, or wall deflection.
Ready to remodel
Planning finished living space, ensuring foundation moisture is permanently sealed first.
Not sure which applies? and we'll sort it out on site.
Services
Waterproofing &
foundation solutions.
Four core services that keep water out and stop foundation movement — plus remodeling once the basement is dry.
Exterior Barrier
Exterior Waterproofing
Excavation and membrane barrier to block groundwater before it touches your foundation.
- Deep foundation wall excavation
- Elastomeric rubber + dimple board
- Perforated footing French drain
Subfloor Drainage
Interior Waterproofing
Sub-floor perimeter drainage that relieves hydrostatic pressure and keeps floors bone dry.
- Sub-slab perimeter French drain
- Cast-iron sump + battery backup
- Heavy-duty vapor wall barrier
Yard & Downspout
French Drains & Drainage
Surface water routing that channels roof runoff and pooling yard water safely away.
- Buried solid PVC downspout lines
- Catch basins & lawn curtain drains
- Daylight / dry well compliant discharge
Structural Repair
Foundation Repair
Structural reinforcement and leak sealing for cracked or shifting masonry walls.
- Pressure epoxy & urethane injection
- Carbon fiber reinforcement straps
- Masonry mortar repointing & tiebacks

Explore basement remodelingThe Process
One assessment.
A clear plan.
Education first. We tell you what we found and what the options involve before any work is scoped.
Inspect the site
Visible entry points, exterior yard grading, downspout paths, cove joint floor conditions, sump pits, and wall alignment.
Explain options & scope
What we found, the realistic options (interior, exterior, or drainage), what each involves, trade-offs, and exact pricing — in writing.
Complete agreed work
Water and foundation issues are properly engineered, installed, tested, and warrantied before any space is closed up or remodeled.
Side-By-Side Comparison
Interior vs. Exterior Waterproofing
Neither method is universally “better.” We evaluate exterior yard grading, wall composition, and discharge legality before recommending a system.
Interior Drainage System
Zero Yard Digging- How it works: Continuous sub-floor trench collects perimeter seepage and directs it to a sealed sump basin.
- Disruption: Confined strictly to basement perimeter; zero disturbance to porches, patios, or landscaping.
- Best for: High hydrostatic water tables and homes with tight lot lines or paved perimeter walks.
Exterior Barrier & Drain
Stops Water Outside- How it works: Excavation to foundation footings, elastomeric membrane coating, dimple board, and footing drain tile.
- Disruption: Requires exterior excavation trench along foundation wall and subsequent ground restoration.
- Best for: Porous cinderblock or masonry walls where water needs to be blocked before penetrating mortar joints.
Homeowner Protection
Diagnosis Before Prescription.
Advice, never upselling.
The biggest fear in waterproofing is being pressured into a $20,000 excavation when a targeted repair solves the problem. Our engineering standard protects your home and your wallet.
Right-Sized Engineering
If a $600 polyurethane crack injection or exterior gutter discharge extension solves your water intrusion, that is exactly what we quote. We will never sell you a full perimeter trench if your home does not need one.
The Price Before the Shovel
Itemized, line-by-line written estimates before any work starts. We detail pump horsepower, drain pipe diameter, barrier membrane gauge, and exact labor. No open-ended hourly billing; no surprise change orders.
UCC Code & Transferable Warranty
Installed to New Jersey Uniform Construction Code guidelines with legal exterior discharge. All permanent perimeter systems include a written warranty that transfers directly to future buyers when you sell your home.
Local Coverage

Verified Local Feedback
Trusted by Bergen County Homeowners
Honest diagnostic scopes, contract-backed workmanship, and bone-dry basements across our service area.
“Water used to seep along our foundation floor seam after every major rain. They accurately diagnosed the hydrostatic pressure and installed an interior perimeter drain with a dual sump backup. Bone dry through three Nor'easters.”
David M.
Ridgewood, NJ
“Other contractors gave us massive blind quotes without even checking our exterior grading. Bergen Basement did a real assessment, showed us how surface runoff was causing our basement wall dampness, and solved it with targeted drainage. No high-pressure sales.”
Elena S.
Tenafly, NJ
“Noticeable stair-step cracks appeared along our cinderblock wall. The assessment explained exactly what was settling versus active water pressure. Repaired the wall structurally and backed it in writing.”

Diagnosis First
What your site assessment includes
We don't sell generic packages. Every visit follows a 4-point diagnostic protocol before recommending work.
1. Moisture Source Tracing
Pinpoint whether moisture is hydrostatic ground pressure, wall seepage, cold-joint leakage, or condensation.
2. Foundation Check
Assess wall alignment, stair-step cracks, efflorescence, and horizontal displacement to separate cosmetic from structural.
3. Exterior & Discharge
Inspect yard grading, roof downspout drainage routes, and local discharge legality before proposing interior vs exterior.
4. Written Itemized Scope
A transparent written summary of realistic options, scope limits, and exact pricing with no high-pressure sales pitch.
