Waterproofing experts to the rescue

Laura Briedis • May 12, 2026

Minor leaks and musty smells may seem harmless, but they’re often the first warning signs of serious basement trouble. It’s time to protect your home from costly damage.

A stack of books sits on a wooden table, next to a lit candle and a warm cup of coffee or tea.

Olivieri & Son has built its reputation as the waterproofing experts by helping homeowners keep their basements dry and foundations strong for nearly half a century.


A basement should be a place for storage, movie nights, a home gym, or anything you need more space for—not surprise puddles and musty smells.


Water in your basement, no matter how minor it seems, is never just a cosmetic issue. It’s often an early warning sign that your home is under stress.


“Most serious basement water problems don’t start with a flood—they start with small, easily overlooked warning signs,” says Mark Olivieri, the “son” in Olivieri & Son. 


When to Call a Waterproofing Expert

Even a minor amount of water intrusion can lead to mold growth, musty odors, cracks in foundation walls, flooded basements during heavy rains, and water pooling around the exterior of the house.


If caught early, however, homeowners can often minimize damage from water seepage before it leads to costly structural repairs. Knowing when to call a basement waterproofing professional is key to protecting your home.


You should contact a waterproofing expert for an inspection:

  • If you notice any water in your basement.
  • If you see any mold or a white chalky residue known as efflorescence.
  • When cracks or leaks are visible in foundation walls.
  • During the rainy season to proactively inspect and improve drainage systems.
  • If you are planning to finish your basement and want to ensure it is properly waterproofed before remodeling begins.


In business since 1981, Olivieri & Son has built its reputation as the waterproofing experts by helping homeowners keep their basements dry and foundations strong for nearly half a century. Locally owned and family operated, the company specializes in basement waterproofing, foundation repair and sewer services.


“We have decades of experience, along with a fleet of trucks and specialized equipment, to manage everything from small repairs to large-scale projects,” Mark says.


Adding Egress Basement Windows

Olivieri & Son can also add egress windows to a basement—either as part of a waterproofing project or as a stand-alone improvement. These specialized windows can transform a basement from dark and limited into a safe, functional and inviting living space.


“Egress windows provide a critical emergency exit in case of fire and significantly improve safety for anyone using the basement as living space,” Mark says. “They also allow natural light and fresh air to flood in, making the basement feel brighter, larger and more comfortable for everyday use.”

“Beyond safety, egress windows can increase a home’s usable square footage and overall value,” Mark adds. “Basements with proper egress can legally be counted as living space, making them ideal for bedrooms, offices or guest suites.”


Pinpointing Sewer Blockages

Olivieri & Son handles all things underground, including sewer inspections and repairs. Sewer problems often develop gradually and identifying them early can save homeowners from major disruption and expense.


Using advanced camera inspection technology, technicians can assess sewer lines without digging up yards or driveways.


“We identify cracks, tree root intrusion, blockages and corrosion,” Mark says. “By sending a camera into the sewer line, we can see exactly what’s causing the problem. In many cases, a simple cleaning or jetting clears the blockage. If a repair is needed, we know precisely where to dig so we don’t have to tear up the entire yard.”


After the inspection, homeowners receive a detailed video report along with recommended solutions. Whether the fix is simple or more involved, Olivieri & Son helps homeowners clearly understand their options so they can make confident, informed decisions about protecting their home.
