Stop Fighting Mold. Fix What Causes It.
Basement waterproofing and mold remediation for New Jersey homes built on moisture-prone foundations.
What you see in your basement is rarely the full story. In this short video, we explain how moisture enters foundations and why mold keeps returning when the source isn’t addressed.

Clearly, your problem runs deeper than your eyes can see.
And that's exactly what's happening.
When moisture seeps into foundations or crawl spaces, it creates the perfect breeding ground for hidden pocikets of mold that are notoriously difficut to get rid of.
Sure, you can bleach the walls, open the windows, and think that some fresh air will solve the problem...
But Mold spores are tricky.
And unless you handle them with care, they almost always come back.

🔦 SPOTLIGHT
Recent Project | East Orange, NJ
This multi-unit basement presented with visible fungal growth, standing water along the perimeter, and persistent moisture intrusion. On-site measurements recorded relative humidity exceeding 74 percent, confirming an active moisture condition rather than a surface issue.
Heritage installed a full interior drainage system paired with a sealed sump basin to manage groundwater entry and relieve hydrostatic pressure. Following installation, basement humidity stabilized below 55 percent, removing the environmental conditions required for mold regrowth.
Which is Where Heritage Waterproofing & Mold Remediation Makes a Difference.
We eliminate the conditions that allow mold to grow by controlling moisture at its source. Our process follows a phased system designed to stabilize basement environments and prevent regrowth.
Phase 1: Moisture Diagnosis
We identify groundwater entry points, humidity drivers, and foundation vulnerabilities.
Phase 2: Water Control and Waterproofing
Interior French drain systems and foundation waterproofing manage hydrostatic pressure and active water intrusion.
Phase 3: Air-Safe Mold Remediation
Targeted removal, treatment, and air quality stabilization restore healthy indoor conditions.

The Heritage Approach
Fix the Source, Not the Symptom
You probably think that our mission when visiting your home is to dig up and destroy every mold spore in your home; however, that's only a part of the equation.
Yes, we'll ensure that every mold spore is dealt with thoroghly .
But Really, mold is just a symptom of a deeper issue.
One that sneaks its way behind your drywall, beneath your floors, and into your ceiling, and will continue to bring mold to life in your home, no matter how many times we kill it --
MOISTURE.
That's why every project starts with a full indoor envirmeonment assessment, including moisture mapping, air sampling, and structural inspection.
Once we understand where the moisture is coming from, we buildid a long-term plan to remove, treat, and prevent mold from every returning.
Our focus is on solving this problem permanentely, so every system we install is built using professional-grade materials rated for durability and is backed by a lifetime warranty.

Why Home & Business Owners Choose Heritage
Solving your mold problem does a lot more than just getting rid of that 'musty' smell in the basement.
It makes your home a happier, healthier, and more comfortable place to live.
According to the CDC, mold irritages the lining of our lungs and throat, causing coughing, wheezing, and sneezing.
And the reactions are even more severe for this with asthma, allergies, or a compromised immune system.
(Plus! It boosts your long-term home value and the quality of the aire you breathe from day to day.)
Why Mold and Water Problems Are Common in New Jersey Homes
Basement moisture issues in New Jersey are strongly influenced by regional soil composition and subsurface water behavior. Different areas of the state contain distinct soil types that affect how groundwater moves and how pressure builds against foundations.
Northern New Jersey and the Piedmont Region
Areas such as Montclair, Bloomfield, West Orange, and Maplewood sit within the Piedmont physiographic province. Soils in this region are dominated by clay-rich silts and weathered shale, including Brunswick Formation-derived soils.
These soils have:
-Low permeability
-High water retention
-Slow drainage characteristics
During rainfall, water accumulates in the soil matrix rather than draining downward. This causes sustained hydrostatic pressure against foundation walls, particularly below grade. Concrete block foundations are vulnerable because moisture migrates through porous block cores and mortar joints.
Central New Jersey and Glacial Till Zones
Communities such as Edison, Bridgewater, and Somerville contain mixed soils influenced by glacial deposits. These soils often consist of compact till with embedded clay lenses.
This creates uneven water movement:
-Water drains quickly through sandy layers
-Water becomes trapped when it encounters clay strata
The result is lateral water movement toward foundation walls, especially at the wall to floor joint, leading to seepage and chronic dampness.
Coastal Plain and Southern New Jersey
Southern and coastal areas such as Toms River and Cherry Hill are built on sandy Coastal Plain soils. These soils drain more freely but present a different challenge.
High groundwater tables combined with poor stormwater management can cause:
-Rapid water table rise during storms
-Saturation below slab level
-Moisture vapor transmission through concrete floors
This results in elevated humidity rather than visible flooding, which still creates favorable conditions for mold growth.
Why Soil Type Matters for Mold Prevention
Soil composition determines how water behaves below grade. When drainage is slow or groundwater levels fluctuate, moisture remains in contact with foundation materials for extended periods. This leads to:
-Persistent basement humidity
-Efflorescence and moisture staining
-Conditions that support mold colonization
Effective waterproofing systems are designed to manage these soil-specific behaviors by relieving pressure, intercepting water entry, and stabilizing indoor humidity.

What our customers say
Markus Thiele
Livingston
"We'd had three companies 'remove" the mold before calling Heritage. They were the only ones who actually determined where the moisture was coming from. Very happy with the outcome. Hightly recommend."
Elena Moreno
Roselle Park
"Worked with Heritage Renovations of New Jersey to install a french drain in our basement. The team walked me through every step, sent photos during the installation process, and left the basement clean The aire even smells a lot better now."
Daniel Koch
Montclair
“We hired Heritage Renovations to address ongoing moisture and mold concerns in our restaurant’s lower level in Montclair. From the initial inspection through completion, their team was thorough, organized, and clearly experienced with commercial environments. They installed a permanent waterproofing solution and performed mold remediation without disrupting daily operations. The space is now dry, odor-free, and fully compliant. We would confidently recommend them to any restaurant or commercial property owner.”
